When Portsmouth, NH property owners need spray foam roofing, 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 Portsmouth crews have seen every spray foam roofing scenario New Hampshire weather can create. We use that experience to select the right foam type, coating system, and application method for your specific property — delivering spray foam roofing results that hold up to Portsmouth conditions year after year.
From inspection to completion, here is how we deliver professional spray foam roofing results.
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.
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.
Application is performed by certified spray foam technicians using the latest proportioning equipment. We monitor foam temperature, pressure, and ratio throughout application to ensure every square foot meets manufacturer performance specifications.
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.
