Where Flashing Problems Happen
Flashing protects places where water could enter the roof system.
Chimneys
Chimney flashing can loosen, corrode, or separate over time.
Skylights
Improper sealing around skylights can create slow leaks.
Roof Valleys
Valleys move large amounts of water and need reliable flashing.
Pipe Boots and Vents
Rubber boots and seals can crack or fail with age.
Why Flashing Repairs Matter
Small flashing failures can cause damage beyond the roof surface.
Hidden Leaks
Water can travel behind walls or into attic spaces before stains appear.
Targeted Repairs
Flashing repairs may be less costly than replacing broader roof areas.
Material Matching
Metal type, sealants, and surrounding roof materials can affect cost.
Aging Seals
Older sealants and boots become brittle and less reliable.
Homeowner Checklist
- Check around chimneys, vents, skylights, and valleys after storms.
- Look for stains near fireplaces, attic vents, or upper walls.
- Avoid relying only on caulk for recurring flashing leaks.
- Estimate repair costs before deciding between patching and broader repair.
