Flashing Failure
Flashing seals the joints between your roof and chimneys, vents, skylights, and walls. When it fails, water finds its way in. Flashing issues cause a significant percentage of all roof leaks.
Where Flashing is Used on Your Roof
Chimney Flashing
Where chimney meets roof—one of the most common leak sources.
Vent Pipe Flashing
Rubber boots around plumbing vents crack from UV exposure.
Skylight Flashing
Complex geometry makes skylights vulnerable to leaks.
Valley Flashing
Metal channels where two roof planes meet handle heavy water flow.
Drip Edge
Metal along roof edges directing water into gutters.
Step Flashing
L-shaped pieces where roof meets walls (dormers, sidewalls).

Frequently Asked Questions
How do I know if my flashing is failing?
Look for visible rust, cracks, lifted edges, or gaps in caulking. Inside, water stains near chimneys, vents, or walls often indicate flashing problems. Leaks that appear only during heavy rain or wind-driven rain are classic flashing failure signs.
Can flashing be repaired or does it need replacement?
Minor issues like cracked sealant can be repaired. However, rusted, corroded, or improperly installed flashing usually needs replacement. We assess each situation and recommend the most cost-effective long-term solution.
Why does coastal salt air affect flashing?
Salt accelerates corrosion of metal flashing, especially galvanized steel. We recommend aluminum or copper flashing for oceanfront properties. Stainless steel fasteners also prevent rust bleeding.
