Professional roof waterproofing for St. Louis 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 St. Louis are engineered to handle indefinite ponding — the silicone topcoat does not re-emulsify, soften, or deteriorate in standing water.
Property owners in St. Louis trust Lapolla Industries for professional roof waterproofing because we combine industry-leading spray foam technology with the local expertise needed to address Missouri climate challenges. Every project begins with a thorough assessment of your property and ends with a warranted solution engineered to last.
Our St. Louis 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.
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.
Proper surface preparation is critical for spray foam adhesion and long-term performance. Our crews clean, dry, and prime all surfaces, remove debris and loose material, and ensure the substrate meets manufacturer specifications before any foam is applied.
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.
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.

Honest reviews from property owners who chose Lapolla Industries for their roofing and insulation needs.
"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."
"We manage a 40,000 square foot retail center and the roof was near end of life. Instead of tearing it off they restored it with a spray foam and coating system. Saved us over sixty percent versus replacement and added twenty years of life."
"Water was coming in around our skylight every time it rained. Lapolla Industries traced it to deteriorated sealant and improper flashing. They redid everything and we have been bone dry through two heavy storm seasons now."
