Chimney Flashing Repair

If you've noticed a ceiling stain that only shows up near where the chimney passes through the roof, flashing is almost always the cause — not the roof shingles themselves.

Why Flashing Fails First

Flashing is the metal seal where the chimney meets the roofline. It moves slightly with temperature changes and settles differently than the roof deck, so the seal degrades faster than the shingles around it.

Diagnosing the Leak

We check both the step flashing along the sides and the counter-flashing set into the mortar joints — a leak can come from either, and they're repaired differently.

Repair Approach

Most flashing repairs involve resealing or replacing sections without disturbing the surrounding roofing, so it's typically a faster, less invasive fix than people expect.
