Waterproofing a roof in Winthrop, ME 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 Maine rain can find a path inside.
When Winthrop, ME 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 Winthrop crews have seen every roof waterproofing scenario Maine 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 Winthrop conditions year after year.
How our certified crews deliver precision roof waterproofing in Winthrop, ME.
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.

"Lapolla Industries installed a spray foam roof on our warehouse last spring. Their crew was thorough, professional, and finished ahead of schedule. The building stays cooler in summer and the roof looks pristine a year later."
"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."
