In Mankato, MN, the difference between a spray foam job that lasts and one that fails comes down to the contractor.

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.
Every project begins with a thorough inspection of your property. We evaluate the existing condition, identify problem areas, and use infrared moisture scanning when needed to reveal hidden issues. You receive a detailed report with photos and honest recommendations.
Our preparation process includes substrate inspection, cleaning, moisture testing, and priming. We mask all areas not receiving foam, set up containment where needed, and verify that temperature and humidity conditions are within specification for application.
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.
After the foam cures, we apply a UV-protective coating — silicone, acrylic, or elastomeric — selected for your specific application and climate. We then remove all masking, clean up the work area, and conduct a final walkthrough with you to verify satisfaction.

Honest reviews from property owners who chose Lapolla Industries for their roofing and insulation needs.
"Had spray foam applied to our flat commercial roof and the difference is night and day. No more ponding water, energy bills dropped noticeably, and the seamless membrane means zero leak points. Should have done this years ago."
"Our corrugated metal roof was rusting at every fastener and seam. They cleaned the entire surface, treated the rust, and applied a thick elastomeric coating. The roof looks brand new and is completely sealed now."
"Called about a ceiling stain that kept growing. They got on the roof, found the leak source at a HVAC curb penetration, and had it sealed within hours. Professional, fast, and the price was exactly what they quoted."
