When a Baton Rouge downpour hits, water finds the weakest point on any roof first: the flashing. Flashing, Chimney & Skylight Repair in Baton Rouge is the work that stops leaks at chimneys, skylights, valleys, and wall transitions before they rot decking and stain ceilings. We have been bending and installing metal flashing here since 2009, through Gustav, Ida, and every spring hail event in between. From Spanish Town Creole cottages to slab homes in Shenandoah and the Country Club of Louisiana, we fabricate flashing on site so it fits the actual roof, not a generic piece from a box. If a leak is already inside, start with our metal roof leak repair page and we will trace it to the source. Call (225) 465-0909 and we will get eyes on it.
Why Flashing Fails So Fast in Baton Rouge Heat and Downpours
Baton Rouge sits on the first bluff above the Mississippi, with bayous and bottomland close by, and the summer pattern is brutal: weeks of heat followed by heavy downpours that dump an inch in under an hour. That cycle works flashing loose at every seam. Add hurricane-driven wind and spring hail, and the weakest joints go first.
- Chimney counterflashing pulls away from brick as the masonry and metal expand at different rates in the heat.
- Skylight curbs crack at the sealant line, and water tracks under the frame instead of over it.
- Valley metal rusts through on older homes in the Garden District and Capital Heights where original flashing is past its life.
- Wall step flashing separates from siding on 1950s brick ranches in Southdowns and Kenilworth after repeated wind events.
- Fastener heads and panel laps on exposed-fastener roofs back out and open a path for water at penetrations.
Every one of these shows up as a ceiling stain far from the actual leak, which is why we probe and water-test before we quote.
Key info: After Ida in 2021, we repaired chimney flashing on dozens of homes in Broadmoor and Sherwood Forest where wind had lifted the counterflashing but the panels held. The roof was fine. The flashing was not.

How We Repair and Fabricate Flashing on Baton Rouge Roofs
We do not patch flashing with a tube of caulk and call it done. We measure the penetration, bend new metal to match the roof pitch and profile, and install it so water sheds over the joint instead of sitting in it. On standing seam roofs we use compatible clips and sealant, and on corrugated panels we match the rib profile so the flashing seats flat.
- We inspect the leak from inside the attic and on the roof, then water-test to confirm the entry point.
- We remove the failed flashing, old sealant, and any rotted decking or curb material underneath.
- We fabricate new flashing in our shop or on site from coil stock sized to the chimney, skylight, or wall.
- We install it with proper laps, fasteners, and sealant rated for Louisiana heat and UV.
- We water-test again and photograph the finished work for your records.
That sequence matters most on historic homes in Beauregard Town and Spanish Town, where a chimney is often original masonry and the flashing has to move with it.
Key info: A homeowner in Oak Hills Place had a skylight leaking into a closet for two summers. Two prior contractors resealed the frame. We found the curb itself was built too low and water was backing under it in heavy rain. New curb, new flashing, leak gone.
If the leak traces back to loose fasteners rather than flashing, see our screw replacement and re-fastening service.
Flashing Repair Approaches We Use in Baton Rouge
Not every leak needs the same fix. We match the approach to the roof type, the age of the home, and how much of the original flashing is still sound.
| Approach | Description | Best for |
|---|---|---|
| Targeted flashing replacement | Remove and replace one failed section with new bent metal. | Isolated leaks at a chimney or wall on a sound roof. |
| Full chimney re-flash | New base, step, and counterflashing cut into the masonry. | Older brick chimneys with failed original flashing. |
| Skylight curb rebuild | Rebuild the curb to proper height and install new flashing. | Skylights that leak at the frame or back up in heavy rain. |
| Valley metal replacement | New formed valley metal under the panel or shingle course. | Rusted or split valleys on 1920s to 1970s homes. |
| Custom on-site fabrication | Bent from coil stock to match unusual pitch or profile. | Historic homes and non-standard penetrations. |
We confirm the right approach with a water test before and after, so you know the repair holds before we leave.
Flashing, Chimney & Skylight Repair Cost in Baton Rouge: What to Expect
Most flashing repairs in Baton Rouge start at $600 and go up from there. That starting figure covers a straightforward single-penetration repair: one chimney, one skylight, or one wall section, with new metal and sealant. The price climbs with access difficulty, roof pitch, how much decking or masonry is damaged, and whether we are working on a historic home where the flashing has to be custom-bent.
Two-story homes in the Garden District and around the University Lakes cost more because of ladder and staging time. A full chimney re-flash on a tall brick chimney runs well above the base. Skylight curb rebuilds sit in the middle. Getting two or three written estimates is smart, and any contractor who will not put the scope in writing is one to skip. Our full pricing overview breaks down the ranges by job type.
What to Look for When Hiring a Metal Roofing Contractor Near Baton Rouge
Flashing work is small in square footage but high in consequence. A bad repair lets water into the structure for years before you see it. Ask hard questions before you sign.
- Confirm the contractor is licensed and carries general liability and workers comp insurance, and ask for a certificate.
- Get at least two or three written estimates that spell out the scope, materials, and warranty.
- Ask for references from jobs in your part of Baton Rouge, ideally on the same roof type and age.
- Understand the permit rules: work on a chimney or structural skylight curb may require a permit, and historic districts like Spanish Town and Beauregard Town may restrict visible metal and color.
- Check HOA design rules in subdivisions like Shenandoah before any visible flashing or skylight work.
