Flashing is one of the most important—and most overlooked—parts of a roofing system.
What Is Flashing?
Flashing is thin metal (usually aluminum or galvanized steel) installed around roof joints and penetrations to redirect water away from seams.
Where It’s Used:
-
Chimneys
-
Skylights
-
Valleys
-
Roof edges
-
Around vents and pipes
Common Flashing Issues:
-
Rust or corrosion
-
Improper installation
-
Cracked caulking or sealant
Pro Tip: Leaks near a chimney or vent are often flashing failures, not shingle problems.
