How our certified crews deliver precision metal roof coating in Winona, MN.
Our assessment process goes beyond a visual check. We examine substrate conditions, drainage patterns, existing insulation performance, and structural integrity. This data-driven approach ensures we recommend the right spray foam solution for your specific property.
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.
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.
The final step is applying a protective topcoat that shields the SPF from UV exposure and provides the weather surface. We select the coating type based on your roof slope, ponding conditions, and desired service life. After coating, we clean up completely and review the finished project with you.

Real feedback from property owners who trusted Lapolla Industries with their spray foam projects.
"We manage a 40,000 square foot retail center and the roof was near end of life. Instead of tearing it off they restored it with a spray foam and coating system. Saved us over sixty percent versus replacement and added twenty years of life."
"Attic insulation upgrade from blown-in to spray foam. The crew masked everything off properly and the overspray was minimal. The temperature in our attic dropped dramatically and so did our energy bills. Worth the investment."
"Straight-line winds peeled back a section of our flat roof membrane during a severe thunderstorm. Lapolla Industries had a crew out the next morning to tarp and secure it. Full repair completed by end of week. Lifesavers when we needed them most."
