Professional roof waterproofing for Mendham property owners. Lapolla Industries delivers lasting results with industry-leading SPF technology.
For Mendham property owners dealing with chronic roof moisture problems, our waterproofing approach starts with diagnosis — we identify where water enters and why it ponds — then we apply a seamless SPF membrane that solves both problems permanently.
Property owners in Mendham trust Lapolla Industries for professional roof waterproofing because we combine industry-leading spray foam technology with the local expertise needed to address New Jersey climate challenges. Every project begins with a thorough assessment of your property and ends with a warranted solution engineered to last.
Our Mendham 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.
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.

Honest reviews from property owners who chose Lapolla Industries for their roofing and insulation needs.
"Had spray foam applied to our crawl space walls and rim joists. The difference in floor temperature upstairs is dramatic. Our furnace cycles less and the energy savings paid for the project faster than they estimated."
"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 restored the roof on our distribution warehouse without any disruption to our operations. The crew worked in sections and we never had to shut down. The new reflective coating has already reduced our cooling load."
