Why Roofing Costs Are Rising in 2026
If you have been considering a roof replacement, you have probably noticed that quotes are higher than they were a year ago. This is not normal inflation — it is a direct result of new and expanded trade tariffs that are rippling through the entire roofing supply chain.
The core issue is straightforward: the United States imports significant quantities of the raw materials and chemical inputs used to manufacture roofing products. When tariffs of 50% are applied to imported steel and aluminum (doubled from 25% in June 2025), copper tariffs hit 50% driving prices to a record $5.69/lb, and anti-dumping duties of 60% on MDI and 272.7% on TCPP are imposed on critical chemical inputs from China, those costs flow directly to manufacturers, then to distributors, then to contractors, and ultimately to homeowners. Building material costs are now 34% above December 2020 levels, with construction input prices rising 0.7% month-over-month.
Unlike seasonal price fluctuations or temporary supply disruptions, tariff-driven price increases tend to be permanent. Historical data from the 2018-2019 steel and aluminum tariffs shows that roofing material prices never returned to pre-tariff levels, even after exemptions were granted. The 2026 tariff environment is broader and more severe, affecting not just metals but the chemical building blocks of shingles, membranes, and underlayment products.
Key Takeaway
Every roofing material category is affected. Metal roofing faces the most severe impact (~60% increase due to 50% steel/aluminum tariffs), followed by TPO/single-ply membranes (12-18%), tile (8-15%), and asphalt shingles (6-10% with another 4-8% from April manufacturer hikes). The national average project is now projected at $20,500-$21,500. These increases are cumulative and accelerating — four major manufacturers have announced April 2026 price increases on top of their January 2026 round.

How Tariffs Affect Each Roofing Material
Not all roofing materials are equally affected. The tariff impact depends on where raw materials are sourced, how much of the manufacturing supply chain crosses international borders, and whether specific duties target the finished product or just its inputs. Here is the material-by-material breakdown.
Asphalt Shingles (Architectural)
Tariff source: Chemical inputs (MDI at 60%, TCPP at 272.7%), fiberglass mat, petroleum derivatives
While shingles are manufactured domestically by GAF, Owens Corning, CertainTeed, and Atlas, their raw material supply chain is globally sourced. MDI (methylene diphenyl diisocyanate), a critical adhesive and sealant component, faces 60% anti-dumping duties on imports from China. TCPP flame retardants face tariffs of 272.7%. Fiberglass mat inputs and petroleum-based asphalt are all subject to new or expanded tariffs. All four major manufacturers have announced April 2026 price increases: GAF (5-8% effective April 15), Owens Corning (4-8% effective April 1), CertainTeed (4-8% effective April 15), and Atlas (4-8% effective April 1). Building material costs are now up 34% since December 2020.
Pre-Tariff Cost
$4.50-$8.00/sqft installed
Post-Tariff Cost
$5.10-$9.20/sqft installed
Standing Seam Metal Roofing
Tariff source: 50% Section 232 tariffs on steel/aluminum (doubled June 2025), 50% copper tariffs
Metal roofing bears the most direct and severe tariff impact. Section 232 tariffs on imported steel and aluminum doubled from 25% to 50% in June 2025, and copper tariffs hit 50% with prices reaching a record $5.69/lb. Metal roofing prices are up approximately 60% as a result. Standing seam panels, metal shingles, exposed-fastener panels, aluminum roofing, and copper flashing are all affected. Even domestically produced metal has increased in price as US mills match the tariff-adjusted market. Zinc and Galvalume coatings add additional tariff exposure. For homeowners choosing metal for its 40-70 year lifespan and energy efficiency, the tariff premium is partially offset by the longer replacement cycle — but the upfront cost increase is substantial.
Pre-Tariff Cost
$9.00-$16.00/sqft installed
Post-Tariff Cost
$14.40-$25.60/sqft installed
TPO and Single-Ply Membranes
Tariff source: Chemical feedstock tariffs, polymer resin tariffs, imported membrane rolls
TPO (thermoplastic polyolefin) and PVC single-ply membranes are manufactured from petrochemical-derived polymers that face multiple tariff exposures. Polypropylene and polyethylene resins, plasticizers, UV stabilizers, and fire-retardant additives are all subject to tariffs on chemical imports. Some membrane rolls are imported directly from overseas manufacturing facilities and face finished-goods tariffs. The flat roofing market is particularly sensitive because commercial property owners often compare re-roofing costs against lease terms and operating budgets.
Pre-Tariff Cost
$5.50-$9.00/sqft installed
Post-Tariff Cost
$6.15-$10.60/sqft installed
Clay and Concrete Tile
Tariff source: Import tariffs on finished tile, tariffs on kiln fuel and colorant chemicals
Domestically produced clay and concrete tile faces moderate tariff impact through kiln fuel costs and imported colorant chemicals. However, a significant portion of the US tile market relies on imports from Mexico, Spain, Italy, and China — all of which face varying tariff rates. Concrete tile is somewhat less affected because cement and aggregate are primarily domestic, but reinforcing fiber, sealants, and colorants are tariff-exposed. The weight of tile means freight costs — already high — are amplified by fuel surcharges linked to energy tariffs.
Pre-Tariff Cost
$8.00-$14.00/sqft installed
Post-Tariff Cost
$8.65-$16.10/sqft installed
Price Increase Timeline: What Has Happened and What Is Coming
Tariff-driven price increases do not happen all at once. They roll through the supply chain in waves — first hitting raw material suppliers, then manufacturers, then distributors, and finally contractor pricing. Here is the timeline of what has already occurred and what industry analysts project for the remainder of 2026.
Section 232 Steel/Aluminum Tariffs Expanded
The 25% tariff on imported steel and aluminum was expanded to close previous exemptions for certain product categories, including finished steel roofing panels and aluminum trim components. Metal roofing manufacturers began adjusting distributor pricing within 30-60 days.
Section 232 Tariffs DOUBLED to 50%
Section 232 tariffs on steel and aluminum were doubled from 25% to 50%, the single most impactful tariff escalation for roofing materials. Copper tariffs also hit 50%, driving copper prices to a record $5.69/lb. Metal roofing prices jumped approximately 60% as a direct result. This affected standing seam panels, metal shingles, aluminum gutters, copper flashing, and every metal component in a roofing system.
Anti-Dumping Duties on MDI from China (60-272%)
The Department of Commerce finalized anti-dumping and countervailing duty orders on MDI (methylene diphenyl diisocyanate) imports from China, with combined duty rates of 60% to 272% depending on the producer. MDI is a critical input for roofing adhesives, sealants, and spray-foam insulation.
Manufacturer Price Increases: Round 1
GAF, Owens Corning, and CertainTeed announced 5-7% price increases on asphalt shingle product lines, citing raw material cost pressures. Metal roofing manufacturers including ATAS, Firestone, and Sheffield Metals raised prices 12-18%. Most increases took effect August-September 2025.
Manufacturer Price Increases: Round 2
A second round of price increases hit the market, with shingle manufacturers adding another 3-5% and metal producers adding 5-8%. TPO and PVC membrane manufacturers raised prices 10-14%. Distributors reported significant forward-buying by contractors trying to lock in lower pricing. Construction input prices were rising 0.7% month-over-month. Building material costs had climbed 34% since December 2020.
Reciprocal Tariffs on Canadian Lumber
New reciprocal tariffs announced in early 2026 are affecting Canadian softwood lumber imports, directly impacting roof decking and sheathing costs. OSB and plywood used for roof decking are seeing 8-12% price increases. Since decking replacement is required on many re-roofing projects (especially older homes), this adds another $500-$1,500 to total project costs on top of the material tariffs.
Manufacturer Price Increases: Round 3
Four major manufacturers announced another round of price hikes: GAF (5-8% effective April 15), Owens Corning (4-8% effective April 1), CertainTeed (4-8% effective April 15), and Atlas (4-8% effective April 1). These increases are driven by the compounding effects of 50% steel/aluminum tariffs, 50% copper tariffs, MDI duties at 60%, and TCPP tariffs at 272.7%. The national average roof replacement project is now projected at $20,500-$21,500.
Manufacturer Sourcing Shifts Continue
Some major shingle manufacturers have begun shifting chemical sourcing away from tariff-affected countries, partially offsetting input cost increases on asphalt shingles. GAF and Owens Corning have announced expanded domestic MDI procurement partnerships. While this has modestly tempered shingle price increases, it has not reversed them — the industry-wide price floor has already been set at the higher level.
Potential Additional Chemical Tariffs
Proposed tariffs on additional chemical inputs used in roofing manufacturing are under review by the US International Trade Commission. If implemented, these could add another 3-5% to shingle and membrane costs by late 2026. Section 232 steel/aluminum tariffs remain at 50% with no relief expected. Copper tariffs remain at 50%.
Projected Stabilization
Industry analysts expect material prices to stabilize at their new, higher levels by late 2026 as supply chains adjust and domestic production capacity expands. However, stabilization means prices plateau — not that they return to pre-tariff levels.
State-by-State Tariff Impact Across Our 12-State Network
Tariffs hit differently depending on where you live. Regional material preferences, proximity to ports and distribution hubs, local labor markets, and state-specific building code requirements all influence how much extra you will pay. Here is how each of our 12 service states is being affected.
High-performance architectural and impact-resistant shingles dominate the MA market, and these products rely heavily on tariff-affected chemical inputs (MDI adhesives, TCPP flame retardants). Ice-and-water shield underlayment costs are up 12-15%. Boston metro labor costs are already the highest in the region, compounding the material increases. Expect 8-12% total project cost increases for shingle roofs and 18-25% for metal.
Connecticut mirrors Massachusetts in material preferences but with slightly lower labor rates. The state's coastal exposure along Long Island Sound drives demand for impact-resistant and wind-rated products, which carry higher tariff sensitivity. Flat/TPO roofing on commercial properties in Hartford and New Haven is seeing 15-20% material increases.
Texas
Texas has the most diverse material mix of any state in our network. Metal roofing, which accounts for a growing share of the Texas market due to hail resistance, faces the steepest tariff impact (~60% increase from 50% steel tariffs). Asphalt shingles face another 4-8% from April manufacturer hikes. The Dallas-Fort Worth and Houston metro areas are seeing aggressive contractor pricing as firms pass through costs. One advantage: Texas's proximity to Gulf Coast refineries partially offsets petroleum-based input cost increases.
Maine
Maine's harsh winters drive demand for premium underlayment and ice-protection systems, all of which face tariff-driven cost increases. Metal roofing is increasingly popular in Maine for snow-shedding performance, putting homeowners directly in the path of steel tariff impacts. Remote delivery to rural Maine communities adds freight cost sensitivity. Expect 10-15% total increases on typical projects.
New Hampshire shares Maine's winter-performance material requirements and sees similar tariff impacts. The state's lack of sales tax on building materials provides a modest buffer, but cannot offset a ~60% metal roofing increase. Standing seam metal roofing, popular in NH for snow management, is facing the full 50% steel tariff markup (doubled from 25% in June 2025).
New Jersey's proximity to major East Coast ports means tariff-affected imported materials arrive first — but price adjustments also hit sooner. The state's mix of asphalt shingle homes in suburban areas and flat TPO/EPDM on commercial properties means broad exposure to both chemical-input and membrane tariffs. Hurricane-rated coastal requirements in Shore communities add premium costs on top of tariff increases.
New York
New York City and Long Island face the highest combined labor-plus-tariff cost pressures in the northeast. Flat roofing materials (TPO, EPDM, modified bitumen) for the city's dense building stock are up 15-20%. Upstate NY's snow belt demands premium ice-protection products with tariff-sensitive chemical components. Across the state, expect 10-18% total project increases depending on material choice.
Pennsylvania has significant domestic steel production, but the 50% tariff on imported steel (doubled from 25% in June 2025) has raised domestic prices industry-wide. Metal roofing in PA is up ~60%. The state's historic architecture in Philadelphia and Pittsburgh often requires slate or specialized materials that are less tariff-sensitive but face higher labor costs. Asphalt shingle projects in suburban PA face another 4-8% from April manufacturer hikes.
Rhode Island's coastal location and dense historic housing stock create a unique tariff exposure. Wind-rated and impact-resistant products for coastal communities face both direct material tariffs and chemical-input tariffs. Newport's historic district requirements for natural slate provide some insulation from tariffs, but specialized flashing and fastener costs are still climbing. Overall project increases of 9-14% are typical.
Vermont
Vermont's local slate quarries provide one of the few tariff-insulated material options in our coverage area. Homeowners choosing Vermont slate benefit from a fully domestic supply chain. However, the majority of VT replacements use architectural shingles or metal, both of which face full tariff exposure. Remote delivery costs to rural Vermont amplify the per-project impact. Energy-efficiency requirements for roofing assemblies add tariff-sensitive insulation costs.
Florida
Hurricane-rated materials face compounding cost pressure from both tariffs AND Florida Building Code (FBC) requirements. Metal roofing — now up ~60% due to 50% steel tariffs — is also the most hurricane-resistant option, creating a painful cost squeeze for FL homeowners. Impact-resistant shingles required in High-Velocity Hurricane Zones use tariff-affected MDI (60% duties) and TCPP (272.7% tariff), adding 10-14% to material costs. Tile roofing, dominant in South Florida, faces 8-15% tariff increases on imported clay and concrete tile from Mexico and the Caribbean.
Title 24 cool roof requirements limit material options, and the tariff-affected materials — metal and specialty tile — are disproportionately used to meet California's energy efficiency mandates. Wildland-Urban Interface (WUI) fire zone requirements further constrain material choices to tariff-impacted products like Class A metal panels and fire-rated tile. Cool-roof coated metal panels face the 50% steel tariff (doubled from 25%) and additional costs for reflective coating chemicals. With metal roofing up ~60% and building materials up 34% since 2020, expect 15-25% total project cost increases in CA, with the highest impacts in WUI zones where fire-rated metal or tile is effectively mandatory.
Should You Replace Your Roof Now or Wait?
This is the most common question homeowners are asking right now, and the answer depends on your specific situation. Here is a decision framework based on roof condition, financial readiness, and market timing.
Replace Now If...
- 1.Your roof is actively leaking or showing failure signs. Water damage to your home's structure, insulation, and interior costs far more to repair than the tariff premium on roofing materials. A $2,000-$4,000 tariff increase on your roof is minor compared to $10,000-$30,000 in water damage remediation.
- 2.Your roof is within 3-5 years of its expected lifespan. An asphalt shingle roof that is 22-25 years old or a metal roof approaching 45-50 years is on borrowed time. Replacing proactively at current tariff-adjusted prices is almost certainly cheaper than replacing reactively at future prices.
- 3.You are planning to sell your home within 2-3 years. A new roof increases resale value and eliminates buyer inspection concerns. Waiting means higher replacement costs and potentially reduced sale price due to an aging roof.
- 4.Your insurance premiums are rising due to roof age. Some insurers charge $300-$800 more annually for roofs over 20 years old, or may refuse to renew coverage entirely. A new roof can reduce your annual premium by 10-25%.
You Can Wait If...
- 1.Your roof is less than 15 years old and in good condition. A sound roof with no active issues has significant remaining life. The tariff premium on a premature replacement would be wasted money. Focus instead on regular maintenance to maximize your current roof's lifespan.
- 2.You only need a localized repair, not a full replacement. If your issue is limited to a few missing shingles, minor flashing repair, or a small leak, a targeted repair at $300-$1,500 is far more cost-effective than a $10,000-$25,000 full replacement at tariff-inflated prices.
- 3.You are unable to fund the project responsibly. Tariff urgency should not push you into predatory financing or drain your emergency fund. If the financial timing is wrong, a well-maintained existing roof is a better financial position than a new roof you cannot afford. See our financing guide for responsible options.
Either Way: Get Your Numbers First
Whether you decide to act now or wait, knowing your current replacement cost is the foundation of an informed decision. An instant satellite estimate from RoofVista gives you an accurate cost baseline using your actual roof dimensions, local material pricing, and current tariff-adjusted rates — without a single phone call or home visit. Compare standardized quotes from pre-vetted local contractors and understand exactly what your project would cost today.
How to Lock In Current Pricing Before the Next Increase
If you have decided to move forward, there are specific steps you can take to protect yourself from additional price increases between now and your installation date.
Get Quotes Now, Even If You Are Not Ready to Start Immediately
Quotes establish a pricing baseline and often include material price guarantees for 30-90 days. Getting quotes from multiple pre-vetted contractors through RoofVista costs nothing and gives you the data you need to make a decision. If prices go up 10% while you are still deciding, you will wish you had a locked-in quote from today.
Ask About Material Hold Agreements
A material hold agreement is a commitment from your contractor (or their distributor) to lock in current material pricing for a set period. In the current tariff environment, many reputable contractors are proactively offering this — purchasing materials in advance or securing distributor price commitments. Ask specifically: "Is the material pricing in this quote guaranteed? For how long? What happens if prices change before my installation date?"
Consider Scheduling for Off-Peak Months
Tariff premiums compound on top of seasonal demand pricing. If you schedule your replacement during a contractor's slower months (typically late fall or early spring, depending on your state), you may save 5-10% on labor even while absorbing the tariff-driven material increase. See our best time to replace your roof guide for state-specific scheduling advice.
Evaluate Material Alternatives
Not all materials are equally tariff-exposed. If you were considering standing seam metal roofing (up ~60% due to 50% steel tariffs), architectural shingles (6-10% increase plus the April 4-8% hike) may offer a better near-term value proposition. Conversely, if you are in a region with domestic slate quarries like Vermont, natural slate's fully domestic supply chain provides relative tariff insulation despite its higher base cost. A side-by-side cost comparison can help you weigh the options.
Get Price Escalation Clauses in Your Contract
If your project has a long lead time (more than 60 days between signing and installation), ensure your contract addresses material price changes. A well-written contract should specify either a fixed total price or a clearly defined escalation clause that limits how much the price can increase and under what circumstances. Avoid open-ended "prices subject to change" language without a defined cap.
What Homeowners Should Do Now
The tariff environment is not going to improve in 2026. Here are the four most impactful steps you can take right now to protect yourself from further cost increases.
Lock in pricing before April 15 manufacturer increases take effect
GAF and CertainTeed increases hit April 15. Owens Corning and Atlas are effective April 1. Contracts signed before these dates with material price guarantees protect you from the increase. Once a quote is locked, your price is your price — even if tariffs escalate further. A fourth round of increases is projected for Q3 2026.
Get an instant satellite estimate now to benchmark your cost
Even if you are not ready to replace today, knowing your current cost is critical. An instant estimate from RoofVista uses your actual roof dimensions and current tariff-adjusted material pricing. This becomes your baseline — if costs rise another 10% by fall, you will know exactly what you missed and can act before the next round.
Compare multiple quotes — tariff pass-through varies by contractor
Not every contractor passes tariff costs to homeowners the same way. Some have forward-bought materials at pre-increase prices. Others have negotiated distributor deals. Some are absorbing part of the increase to stay competitive. The only way to know who is offering the best tariff-adjusted value is to compare standardized quotes side-by-side — which is exactly what RoofVista provides.
Consider materials with lower tariff exposure
Domestically-sourced architectural shingles carry the lowest tariff exposure (6-10% plus the April 4-8% manufacturer hike) of any mainstream roofing material. If you were planning a metal roof (~60% increase from 50% steel tariffs) or imported tile (8-15%), it is worth running the numbers on architectural shingles as an alternative. The tariff savings alone could be $3,000-$8,000 on a typical project. Use our cost comparison tool to see the material-by-material difference for your roof.

The Hidden Tariff: Chemical Supply Chain Impact on Shingles
Most homeowners think of tariffs as affecting finished products — steel panels or aluminum trim. But the most consequential tariff impact on the average homeowner is happening deeper in the supply chain, in the chemical inputs that go into manufacturing asphalt shingles, underlayment, sealants, and adhesives.
MDI (Methylene Diphenyl Diisocyanate) is the chemical backbone of polyurethane adhesives and sealants used in virtually every roofing system. It is also a key component of spray-foam insulation, which is increasingly used in attic insulation during roof replacements. In March 2025, the Department of Commerce finalized anti-dumping and countervailing duty orders on MDI imports from China, with combined rates ranging from 60% depending on the specific Chinese producer. Since China was a major MDI supplier, this has tightened global supply and raised prices for all buyers, regardless of sourcing country.
TCPP (Tris(1-chloro-2-propyl) phosphate) is a flame retardant used in roofing foam products, insulation boards, and some membrane formulations. TCPP now faces tariffs of 272.7%, dramatically raising costs for manufacturers who rely on it to meet fire-resistance building code requirements — which is effectively every manufacturer.
Fiberglass mat, the reinforcing layer inside asphalt shingles, uses glass fibers that are subject to 10-15% tariffs on certain import categories. While major shingle manufacturers have domestic fiberglass supply, specialty mats and higher-performance formulations still draw from global sources.
The result: even a "domestically manufactured" asphalt shingle is exposed to tariffs at multiple points in its raw material supply chain. This is why shingle prices have risen 6-10% despite being made in American factories — the ingredients are global, even when the assembly is local.
How Reputable Contractors Are Responding to Tariff Increases
The tariff environment is testing contractor quality. The best contractors are responding with transparency and proactive pricing strategies. Here is what we are seeing from the pre-vetted contractors in the RoofVista network.
Forward-Buying Materials
Some contractors are purchasing materials months ahead at current prices and storing them, absorbing the carrying cost to offer price stability to homeowners.
Transparent Cost Breakdowns
Quality contractors are itemizing tariff-related material increases separately from labor and overhead, so homeowners can see exactly what is tariff-driven vs. other costs.
Price Lock Guarantees
Many are offering 60-90 day material price locks as part of their proposals, giving homeowners time to make decisions without fear of additional increases.
Material Substitution Guidance
Experienced contractors are advising homeowners on material alternatives that offer better value in the current tariff environment without sacrificing performance.
Red Flag: Tariff Scare Tactics
Be cautious of contractors who use tariffs as a high-pressure sales tactic, claiming "prices double next week" or "this is your last chance." While tariff-driven increases are real, they occur in predictable waves over months, not overnight. Legitimate urgency is measured in weeks and months, not hours. Any contractor who refuses to put pricing in writing or pressures you to sign without time to compare quotes is not operating in your best interest.
Frequently Asked Questions: Roofing Tariffs in 2026
What are the April 2026 roofing manufacturer price increases?
Four major manufacturers have announced April 2026 price increases: GAF is raising prices 5-8% effective April 15, Owens Corning is increasing 4-8% effective April 1, CertainTeed is adding 4-8% effective April 15, and Atlas is implementing a 4-8% increase effective April 1. These increases come on top of the January 2026 round and are driven by 50% steel/aluminum tariffs (doubled from 25% in June 2025), copper tariffs at 50% with record $5.69/lb prices, MDI duties at 60%, and TCPP tariffs at 272.7%. Building material costs are now up 34% since December 2020.
How much are roofing tariffs increasing material costs in 2026?
The impact varies by material. Asphalt shingles are seeing 6-10% price increases due to tariffs on petroleum-derived chemical inputs (MDI at 60%, TCPP at 272.7%) and fiberglass mat components. Metal roofing faces the steepest impact — prices are up approximately 60% due to Section 232 tariffs that doubled from 25% to 50% in June 2025. TPO and single-ply membranes are up 12-18% due to chemical feedstock tariffs. Clay and concrete tile are seeing 8-15% increases where imported from countries subject to tariffs. Construction input prices are rising 0.7% month-over-month as of January 2026. These increases compound on top of normal inflation, making the total year-over-year price jump the steepest in over a decade. The national average roof replacement project is now projected at $20,500-$21,500 after the April increases take effect.
Are asphalt shingle prices going up because of tariffs?
Yes. While asphalt shingles are primarily manufactured domestically, their raw material supply chain is heavily affected by tariffs. The key inputs impacted include: MDI (methylene diphenyl diisocyanate) used in roofing adhesives and sealants, facing 60% anti-dumping duties on imports from China; TCPP flame retardants subject to 272.7% tariffs; fiberglass mat components with 10-15% tariffs; and petroleum-based asphalt affected by broader energy market disruptions. All four major manufacturers — GAF (5-8%), Owens Corning (4-8%), CertainTeed (4-8%), and Atlas (4-8%) — have announced April 2026 price increases on top of their January 2026 increases, citing compounding raw material cost pressures.
Will roofing prices go back down after tariffs are removed?
Historically, roofing material prices have not returned to pre-tariff levels even when tariffs are reduced or removed. The 2018-2019 steel and aluminum tariffs demonstrated this pattern: prices spiked when tariffs were imposed, partially corrected when exemptions were granted, but never returned to baseline. Manufacturers adjust their pricing structures, supply chains reorganize, and the new price floor becomes permanent. The current 2026 tariff environment suggests prices will stabilize at a higher level rather than revert, making the case for locking in current pricing before additional increases take effect.
Should I replace my roof now before tariff prices increase further?
If your roof is within 3-5 years of its expected end of life, or showing signs of failure (leaks, missing shingles, granule loss, sagging), acting sooner rather than later makes strong financial sense. Current pricing, while already elevated, is likely the lowest you will see for the next 2-3 years as additional tariff rounds take effect and manufacturers fully pass through costs. However, if your roof is in good condition with 10+ years of remaining life, premature replacement is not cost-effective regardless of tariff trends. Get an instant estimate now to understand your current cost baseline, then make an informed decision based on your specific roof condition.
How do steel and aluminum tariffs affect metal roofing prices?
Metal roofing is the most directly impacted category. Section 232 steel and aluminum tariffs doubled from 25% to 50% in June 2025, and copper tariffs hit 50% with prices reaching a record $5.69/lb. Metal roofing prices are up approximately 60% as a result. For a typical 2,000 sqft standing seam metal roof that previously cost $18,000-$30,000, tariff-driven material increases add approximately $5,000-$10,000+ to the total project cost. Domestic metal producers have also raised prices to match the tariff-adjusted market, meaning even domestically sourced metal costs more. Some contractors are locking in material pricing 60-90 days ahead of projects to protect homeowners from mid-project price jumps.
What is a material hold agreement and should I get one?
A material hold agreement is a commitment from a contractor or distributor to lock in current material pricing for a specified period, typically 30-90 days. In the current tariff environment, this is an important protection. When you receive a quote, ask your contractor whether the price is guaranteed and for how long. Many reputable contractors are now offering material price locks as part of their proposals, purchasing materials in advance or securing distributor commitments. On a $15,000 project, a 10% price increase during the contract period would add $1,500 — making a material hold agreement well worth requesting.
Are there any roofing materials not affected by tariffs?
No roofing material is completely insulated from tariff impacts, but some are less affected than others. Domestically quarried natural slate is the least tariff-sensitive, as both the raw material and manufacturing are US-based. However, installation tools and fasteners still face tariff pressures. Wood shakes sourced from domestic or Canadian mills face minimal direct tariffs, though Canadian lumber tariffs fluctuate. Recycled-content roofing materials have a partially insulated supply chain. Asphalt shingles, while domestically manufactured, are significantly affected through their chemical input supply chain. Metal and TPO/PVC membranes face the most direct and substantial tariff impacts.
How do tariffs affect roofing costs differently by state?
Tariff impacts vary by state based on several factors: proximity to ports and distribution centers (coastal states see faster price transmission), dominant roofing materials in the regional market (states with high metal roofing adoption like Texas feel steel tariffs more acutely), local labor market conditions (tight labor markets amplify material cost increases as contractors protect margins), and state-level regulations that may require specific tariff-affected materials. For example, Texas and Pennsylvania see larger metal roofing impacts, while northeastern states like Massachusetts and Connecticut feel disproportionate effects on chemical-input tariffs due to their reliance on high-performance shingle products rated for ice dam prevention. Florida faces compounding pressure where hurricane-code requirements push homeowners toward the most tariff-impacted materials (metal and impact-rated shingles). California's Title 24 cool roof mandates and WUI fire zone requirements similarly constrain homeowners to tariff-affected metal and specialty tile products.
