What Is Roof Flashing (And Why It Matters)?
Roof flashing is the protective metal (and related waterproof detailing) installed at roof joints and penetrations to direct water away. When flashing fails, water can get beneath roofing materials and cause interior leaks or hidden damage.
Flashing is commonly found at:
-

Chimneys -

Roof valleys -

Plumbing vent pipes -

Skylights -

Dormers and roof-to-wall connections -

Step flashing at sidewalls
Signs You Need Roof Flashing Repair
Flashing issues can cause leaks that appear far from the source. A small flashing gap can lead to big problems.
Common warning signs include:
-

Ceiling stains or water spots near chimneys or exterior walls -

Leaks during wind-driven rain -

Rusted, loose, or visibly lifted flashing -

Cracked or failing sealant around flashing areas -

Damp attic insulation near roof transitions -

Repeated leaks that return after “patch” work -

Water staining on brick near the chimney (sometimes flashing-related)
