Roof flashing repair in Baltimore
Flashing is the metal that keeps water out where the roof meets a wall, chimney, vent, or skylight. When it fails, the roof leaks.
I'm often up on a roof, so a text usually reaches me fastest, but call anytime.
Roof flashing is the metal that seals the joints where a roof meets a chimney, wall, vent pipe or skylight. When it rusts, pulls loose, or was installed short, water runs behind it and the roof leaks even though the shingles look fine. Most flashing repairs are local and don't need a new roof.
Why does roof flashing fail?
Flashing fails when the metal rusts, pulls away, or was installed too short to shed water. It's one of the most common real causes of roof leaks I see. The shingles look fine, but the metal at the chimney or wall is open.
We replace flashing in those spots and tie it back into the shingles or the flat roof so water sheds the way it should.
If it only leaks in a hard or windy rain, here's why a roof leaks only in heavy rain.
What does a flashing repair include?
We remove the bad flashing, repair any soft wood under it, and install new metal tied into the shingles or flat roof.
Chimney flashing
Step and counter flashing. See also chimney flashing repair.
Wall and dormer flashing
Where a roof meets a vertical wall.
Vents and pipes
Boots and collars that have cracked. A stain near a bathroom is often the vent pipe. Here's how to tell if the vent pipe boot is leaking.
Skylights
Curbs and flashing around skylight frames. If the drip is around a skylight, here's why skylights leak and how to tell a leak from condensation.
Roof flashing questions
Can roof flashing be repaired without a new roof?
Yes. Most flashing repairs are local to the chimney, wall, vent or skylight. We take up the shingles around that spot, replace the flashing, and lay the roofing back down.
What are signs of bad roof flashing?
Stains on a ceiling or wall near a chimney or skylight, rust streaks or bent metal you can see from the ground, cracked caulk at the joints, and wet wood in the attic next to a chimney or wall. If you're not sure where the water is coming from, see roof leak detection and repair.
Caulk can also seal gaps around windows and trim, so here is our exterior caulking service.
Is roofing tar a good fix for leaking flashing?
No. Tar or caulk over flashing is a short-term patch that cracks within a few seasons. A lasting fix is new metal step and counter flashing tied into the roof.
How does flashing work on a rowhouse party wall?
On rowhouses the flashing runs along the parapet or the line where your roof meets your neighbor's. It's one of the most common city leaks. I explain access before we start if the work touches the shared wall.
