Professional flat roof repair for Sioux Falls property owners. Lapolla Industries delivers lasting results with industry-leading SPF technology.
If your flat roof in Sioux Falls has been repaired multiple times and still leaks, the problem is likely systemic — failed seam adhesive, deteriorated flashing, or inadequate drainage slope. Our SD crews identify these underlying issues and resolve them permanently using spray foam and liquid-applied membrane systems.
In Sioux Falls, SD, the difference between a spray foam job that lasts and one that fails comes down to the contractor. Lapolla Industries applies the same quality standards to every flat roof repair project that earned us a reputation as one of the nation's most trusted SPF specialists — proper surface prep, correct foam thickness, and factory-specified coating application.
Every flat roof repair project we complete in Sioux Falls is backed by both manufacturer material warranties and our own workmanship guarantee. We document every step with photos and measurements, provide you with a detailed project report, and remain available for warranty service and maintenance throughout the life of your SPF system.
Our proven process ensures quality results on every spray foam project.
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.
Proper surface preparation is critical for spray foam adhesion and long-term performance. Our crews clean, dry, and prime all surfaces, remove debris and loose material, and ensure the substrate meets manufacturer specifications before any foam is applied.
Using precision spray equipment, our crews apply the foam in controlled passes to achieve the specified thickness and density. The closed-cell foam expands 30 to 40 times its liquid volume, conforming to every detail of the surface and creating a seamless monolithic barrier.
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.

Honest reviews from property owners who chose Lapolla Industries for their roofing and insulation needs.
"Our old three-layer built-up roof was beyond saving. They stripped everything down to the deck, repaired the substrate, and installed a new spray foam roofing system. The building is better insulated now than it has ever been."
"Got a comprehensive inspection done on our warehouse roof. They found three areas of trapped moisture that were invisible from the surface. The early detection saved us from much more expensive structural repairs down the road."
"Our flat roof on a strip mall had been leaking for months. Two other companies just slapped tar on it. These guys actually found the real problem — failed flashing at a parapet wall — and fixed it permanently."
