Flashing prevents water intrusion at vulnerable points like valleys, chimneys, and vents. Quality flashing is essential for a leak-free roof system.

Why Quality Flashing Matters

90% of leaks occur at flashing points

Longevity

Quality flashing lasts 25-50+ years

Damage Prevention

Prevents costly water damage

Warranty Protection

Flashing Critical Points

Flashing must be installed at: chimneys, skylights, vent pipes, valleys, dormers, wall intersections, and roof edges. Missing or damaged flashing is the #1 cause of roof leaks.
