Expert roof replacement in Gretna, LA. Licensed spray foam contractors with manufacturer-backed warranties and free inspections.
When a Gretna roof has reached the end of its serviceable life — saturated insulation, structural damage, or multiple failed repair attempts — Lapolla Industries performs complete tear-off and replacement with modern spray foam roofing systems that deliver superior performance for decades.
When Gretna, LA property owners need roof replacement, they turn to Lapolla Industries for the same reason thousands of customers nationwide do: we solve the root problem, not just the symptom. Our diagnostic approach uses infrared scanning, moisture mapping, and visual inspection to ensure the solution we recommend is the one your building actually needs.
With over two decades of spray foam experience, our Gretna crews have seen every roof replacement scenario Louisiana weather can create. We use that experience to select the right foam type, coating system, and application method for your specific property — delivering roof replacement results that hold up to Gretna conditions year after year.
From inspection to completion, here is how we deliver professional roof replacement results.
Before any work begins, our certified inspectors evaluate your property and provide a comprehensive assessment including current condition, repair needs, and recommended SPF solutions. You get a written estimate with no hidden fees.
We prepare every surface according to factory guidelines — cleaning contaminants, addressing moisture, repairing damaged substrate, and verifying adhesion conditions. This step is not glamorous, but it is the foundation of a spray foam system that lasts decades.
Our factory-trained crews apply spray polyurethane foam using calibrated equipment that ensures consistent thickness, proper density, and complete coverage. The foam expands on contact, fills every gap, and bonds permanently to the prepared substrate.
We finish every project with the appropriate protective coating, thorough cleanup, and a detailed walkthrough. You receive project documentation including photos, material specifications, warranty registration, and maintenance recommendations.

"Had a few spots where birds had pecked through the coating on our foam roof. The repair crew patched every spot and applied a fresh topcoat over the entire section. Looks brand new and no more leaks."
"Regular maintenance visits twice a year keep our flat roof in great shape. They clean drains, check seams, inspect all penetrations, and send a detailed report with photos. Good preventive program at a reasonable cost."
