Expert roof waterproofing in Somersworth, NH. Licensed spray foam contractors with manufacturer-backed warranties and free inspections.
Waterproofing a roof in Somersworth, NH requires more than paint-on products that peel and crack. Lapolla Industries applies spray foam and elastomeric membranes that create a true monolithic waterproof barrier — no seams, no joints, no weak points where New Hampshire rain can find a path inside.
When Somersworth, NH property owners need roof waterproofing, 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 Somersworth crews have seen every roof waterproofing 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 roof waterproofing results that hold up to Somersworth conditions year after year.
From inspection to completion, here is how we deliver professional roof waterproofing 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.

Our reputation is built on results. Here is what our customers have to say.
"Our 18-year-old roof was showing its age but still structurally sound. Lapolla Industries recommended restoration over replacement and it was the right call. New coating, sealed seams, and a 15-year warranty. Smart investment."
"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."
"Lapolla Industries repaired our flat roof after a section of the membrane started bubbling and lifting. They removed the damaged area, applied new substrate, and sealed everything tight. Solid repair at a fair price."
