Professional roof waterproofing for Manchester property owners. Lapolla Industries delivers lasting results with industry-leading SPF technology.
Ponding water destroys conventional roof waterproofing because standing water attacks seams and coating adhesion. Our SPF-based waterproofing systems in Manchester are engineered to handle indefinite ponding — the silicone topcoat does not re-emulsify, soften, or deteriorate in standing water.
Property owners in Manchester trust Lapolla Industries for professional roof waterproofing because we combine industry-leading spray foam technology with the local expertise needed to address New Hampshire climate challenges. Every project begins with a thorough assessment of your property and ends with a warranted solution engineered to last.
Our Manchester roof waterproofing crews arrive fully equipped with the latest SPF application systems, safety equipment, and premium materials. We handle every step — from surface preparation and substrate evaluation to final coating and cleanup — so you get a turnkey result with zero hassle and complete confidence in the finished product.
A systematic approach to roof waterproofing that ensures lasting performance.
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.

"Had a few spots where birds had pecked through the coating on our foam roof. The repair crew patched every spot and applied a fresh topcoat over the entire section. Looks brand new and no more leaks."
"We needed our concrete roof deck waterproofed before installing new equipment on it. The crew applied a monolithic membrane that handles foot traffic and ponding water. Two years in and zero issues. Money well spent."
"Lapolla Industries has been maintaining our spray foam roof for three years now. Every visit they document the condition, clean debris from drains, and address any minor issues on the spot. Peace of mind is worth every dollar."
