Every project begins with a thorough assessment of your property and ends with a warranted solution engineered to last.

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.
Our assessment process goes beyond a visual check. We examine substrate conditions, drainage patterns, existing insulation performance, and structural integrity. This data-driven approach ensures we recommend the right spray foam solution for your specific property.
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.
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.
The final step is applying a protective topcoat that shields the SPF from UV exposure and provides the weather surface. We select the coating type based on your roof slope, ponding conditions, and desired service life. After coating, we clean up completely and review the finished project with you.

"We had a persistent leak that three different contractors could not find. Their team used moisture scanning equipment and pinpointed it to a failed pipe boot in minutes. Fixed it the same day. Incredible diagnostic work."
"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."
"They waterproofed our entire flat roof with a seamless elastomeric membrane. Two years later and not a single drop of water has gotten through. The application was clean and fast — three days for 8,000 square feet."
