Lafayette Roof Pros provides professional flat & low-slope roofing in Lafayette, LA for residential and commercial properties across Acadiana. On a low-slope roof here the vapor drive runs inward most of the year, and that single fact overturns a lot of received wisdom. A vapor retarder placed the way a northern detail book shows it will trap moisture inside the assembly instead of keeping it out.
Sun heats a dark membrane, the moisture in the deck and in the humid air above it is driven downward toward the cool conditioned space, and it condenses at the first surface cold enough to catch it. If someone has installed a low-permeance sheet directly under the insulation, that is exactly where the water collects, and the insulation stays wet for years while the membrane above looks perfect.
So before we quote any low-slope work we find out whether the assembly is wet. That means an infrared scan on a clear evening while the roof gives back its heat, and then core cuts to confirm what the scan suggests, because infrared shows thermal anomalies rather than water and only a core proves it. We take cores at our own risk and patch them the same visit.
The result changes the recommendation completely. A dry assembly with a tired membrane is a recover: mechanically attach new insulation and a new TPO or modified bitumen sheet over what is there. A wet assembly is a tear-off, no matter how good the top looks, because wet insulation has almost no thermal value and quietly corrodes the deck beneath it. We do not recover over wet insulation, and we will decline the job rather than do it.
Slope and drainage still matter, and we correct them with tapered insulation where the structure will not be re-framed, so water clears within a couple of days rather than sitting in a low spot growing biology. On built-up and modified bitumen roofs we detail the terminations at parapets and curbs first, because on flat roofs the field is rarely the problem.
Residential low-slope sections, the back-porch additions and carport tie-ins that are everywhere in this parish, get the same treatment scaled down. A self-adhered modified bitumen cap sheet with properly flashed wall terminations lasts decades. Rolled asphalt nailed over a sagging deck lasts until the next wet season, and we will not install it. Where the tie-in meets a wall we run the base flashing up behind the siding rather than terminating it in a bead of sealant.
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 flat & low-slope roofing
The difference between flat & low-slope roofing that lasts and flat & low-slope roofing 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.
