Lafayette Roof Pros provides professional chimney flashing in Lafayette, LA for residential and commercial properties across Acadiana. A chimney is a hole cut through the roof plane with a masonry sponge sitting in it, which is why it draws more leak calls than its square footage deserves. In our humidity the masonry itself carries water, and a detail that would pass in a dry climate quietly fails.
The correct assembly has two independent layers. Step flashing woven into each shingle course against the brick, then counterflashing let into a reglet groove cut in the mortar, lapped down over those steps and sealed at the groove alone. Those layers move independently as the chimney and the roof expand at different rates through a Gulf Coast summer, and that independence is why the detail lasts.
What we find instead, on roof after roof, is a single piece of metal surface-mounted to the brick face and buried in sealant. It works for about three years. Then the sealant loses adhesion to a masonry surface that has been wetting and drying continuously, and water enters at the top edge with nothing behind it. Recaulking that joint is not a repair, it is a subscription.
On any chimney wider than about thirty inches we build a cricket on the upslope side, a small framed saddle that splits water around the stack instead of asking a flat pan to hold it back. Without one, debris packs behind the chimney, stays wet in this climate and holds moisture against both the flashing and the deck year-round.
Prefabricated chimneys get different attention. Their chase covers are frequently thin galvanized steel that rusts through from the inside, and the first sign is staining on the framing rather than the ceiling. We replace them in stainless or heavy-gauge aluminum with a cross break so water sheds, and we make sure the collar around the flue is sealed to the cover rather than to the flue pipe.
Where the masonry itself is the problem, flashing will not save it. Spalling brick and open mortar joints take on water directly, and in this humidity a chimney can stay damp inside for weeks after a rain, which is long enough to keep the surrounding framing wet. The correct order is repointing first, then flashing. We will say so and hold off scheduling the roof work rather than install good metal against brick that needs a mason.
Our licensed and insured team brings the right materials and equipment to every job — synthetic underlayment, 8d ring-shank sheathing nails, continuous ridge vent, net free ventilation area, Galvalume standing seam panels, closed-cell spray foam at the roof deck — and backs the work with a written workmanship warranty. We serve Lafayette and nearby communities including Broussard, Youngsville, Carencro, Scott.

Materials, equipment and how we do chimney flashing
The difference between chimney flashing that lasts and chimney flashing that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with synthetic underlayment, 8d ring-shank sheathing nails, continuous ridge vent, net free ventilation area, spec them to the job instead of to the invoice, and write the material grades into the free estimate so you know exactly what you are buying.
Every Lafayette job runs the same way: site walk and measurements, written scope and fixed price, protection of the surrounding area, then the work itself with a daily clean-up. Years of roofing work in Acadiana means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.
