Chimney leak repair from the top down
Same-day leak visits in Longwood when the schedule allows, with a temporary cover if repair day must wait.
Base flashing along the roof
Base flashing is the metal that lies on the roof and turns up the chimney face. Along the sides it is often installed as step flashing, woven into each course of shingles so every piece sheds water onto the course below.
When base flashing has been bent, nailed through or covered with sealant instead of properly lapped, water runs under it. We replace failed sections to follow the roofing maker's details and the building code. If the shingles around the chimney are too brittle to lift, we explain how the roofing will be handled before work starts.
Counterflashing set into the masonry
Counterflashing covers the top edge of the base flashing. It is set into a mortar joint cut in the brick and laps down over the base flashing, so water on the chimney face cannot run behind it.
Counterflashing that was only glued to the face of the brick pulls away as the sealant ages. Our team cuts a proper slot into the joint, sets the new metal and seals it with mortar or a suitable sealant. The Brick Industry Association describes this detail for brick chimneys, and it outlasts a surface patch.
Tracing water in the attic
Where the attic can be entered safely, the framing around the chimney often shows the path water has taken. Stains on the decking, damp insulation and rust on nail tips mark where it has been running.
We compare those marks with the exterior conditions above them. That comparison narrows the entry point before any repair is proposed, and it shows you why the repair is aimed where it is. If the attic cannot be reached, the findings say so and rely on the exterior evidence.
Mixed metals on the chimney top
Galvanized steel gives up its zinc faster when it touches other metals in wet conditions, according to the American Galvanizers Association. Mixed fasteners and parts on a cap, a chase top or a run of flashing can rust through early.
Replacement metal parts go on with compatible fasteners and materials, so the new work does not start rusting at its joints. The estimate names the metal chosen for a cap or cover, so you know exactly what goes on the roof.
