Frequently Asked Questions
Can I repair just one section of my roof?
Yes, if damage is localized and your roof is relatively young. However, mismatched shingles may be noticeable, and you'll need to ensure proper integration with existing roofing to prevent leaks.
Will insurance cover repairs or replacement?
Most insurance covers storm damage, but not wear and tear. Replacement is typically covered if damage is sudden and accidental. Age and maintenance history affect coverage.
How long can I wait before making a decision?
Active leaks require immediate attention to prevent structural damage. For other issues, you typically have weeks to months, but delays can turn small repairs into major replacements.
Should I get multiple quotes?
Always get 3-4 quotes for major work. Compare not just price but warranty terms, materials quality, and contractor reputation. Be wary of quotes significantly below others.
