Flashing: The Small Part That Stops Big Leaks
Shingles protect the open field of a roof, but every roof also has joints and openings: a chimney, a wall where a second story or dormer rises, plumbing vents, skylights, and valleys. Flashing is the metal or rubber detail that seals those spots and turns water back onto the shingles. When it fails, water goes straight into the joint.
In Baton Rouge, flashing works hard. Daily heat makes metal expand and contract, rubber pipe boots dry out and split in the sun, and sealant that was used in place of proper flashing tends to crack within a few years. Heavy, wind-driven rain then finds the gap. Many leaks that seem to come from nowhere start at a flashing detail.
Our roof flashing repair service in Baton Rouge focuses on the joint itself. We look at how the flashing was installed, whether it is the right type for the location, and whether the wood behind it has taken on water, then explain the repair before work begins.
Flashing Areas We Repair
Each location on a roof uses its own flashing method. A repair that suits a vent pipe will not suit a brick chimney, so the fix depends on where the leak is and how that joint was built.
Chimney flashing
Chimneys need step flashing along the sides, a front apron, a back piece or cricket on wider chimneys, and counterflashing set into the masonry. Common problems include counterflashing pulling out of the mortar joints and sealant used where metal should be. Repairs range from resetting counterflashing to replacing the full set.
Wall and step flashing
Where a roof meets a vertical wall, individual pieces of step flashing are woven in with each shingle course and tucked behind the siding. Missing pieces, rusted metal, or siding installed too tight to the roof can let water run down inside the wall, often showing up as stains on an interior wall.
Pipe boots and vent flashing
Plumbing vents usually have a rubber collar that seals around the pipe. In strong Louisiana sun these collars can crack and split, letting water run down the pipe into the attic. Replacing a failed boot is one of the most common and least expensive flashing repairs.
Skylight flashing
Skylights need flashing on all four sides, with water directed around the frame and back onto the roof. Leaks can come from the flashing, the seal between glass and frame, or condensation, and telling these apart is part of the repair.
Valley flashing
Some valleys use a metal liner under the shingles. Rust, debris that holds moisture, or nails driven too close to the valley center can let water through. Because valleys carry so much runoff, these leaks can become serious quickly.

How it works
How Flashing Repair Works
- 1
Call with the leak location
Tell us where the water shows up inside and which roof features sit above it, such as a chimney, skylight, or vent pipe.
- 2
Inspect the joint
We check the flashing, the shingles around it, and the attic below where accessible, looking for rust, gaps, failed sealant, and water trails.
- 3
Explain and estimate
You get a plain explanation of what failed and a written estimate covering the flashing, any shingles or siding to remove, and possible wood repair.
- 4
Repair the flashing
Surrounding materials are removed as needed, damaged wood is addressed once you approve it, new flashing is installed, and the roofing is put back in place.
Why Baton Rouge Homeowners Call Us
Proper flashing, not just sealant
Sealant has its place, but it is not a substitute for correctly installed metal. We aim to repair the flashing so it sheds water on its own rather than relying on caulk.
Wood behind the joint checked
Flashing leaks often soak the decking or wall framing for months before they show inside. We check what is behind the flashing and tell you what we find.
The right method for each location
Chimneys, walls, vents, skylights, and valleys each need their own detail. The repair is matched to the joint rather than handled with a one-size patch.
Clear scope and price
If siding, masonry, or other trades are involved, we explain that up front so the estimate reflects the real job.
Questions
Common Questions
My chimney leak was caulked last year and is leaking again. Why?
Caulk applied over failed flashing often cracks or pulls away after a season or two of heat and rain. The lasting fix is usually to repair or replace the flashing so water is turned away by the metal, not held back by sealant.
How can I tell if a leak is from flashing?
Leaks that appear near a chimney, along an interior wall below a roof-to-wall joint, around a skylight, or around a vent pipe in the attic often point to flashing. An inspection on the roof is the most reliable way to confirm it.
Can flashing be repaired without replacing the roof?
Yes. Flashing is usually repaired as a localized job by lifting the surrounding shingles, replacing or resetting the flashing, and reinstalling the roofing. It is one of the most common repairs on roofs that are otherwise in fair shape.
Do pipe boots really fail that often?
Cracked pipe boots are a very common source of roof leaks. The rubber is exposed to strong sun year-round, and once it cracks, water runs straight down the pipe. A quick look at your pipe boots is worthwhile if your roof is more than several years old.
