Our Roof Waterproofing Process

A systematic approach to roof waterproofing that ensures lasting performance.

1

Inspection & Assessment

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.

2

Surface Preparation

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.

3

SPF 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.

4

Protective Coating & Cleanup

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.

★★★★★

"They sprayed closed-cell foam in our attic and the difference was immediate. Our upstairs bedrooms are finally comfortable year-round and our heating bill dropped by about thirty percent. The crew was in and out in one day."

— Edward Yamamoto
★★★★★

"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."

— Mark Townsend
★★★★★

"Our flat roof on a strip mall had been leaking for months. Two other companies just slapped tar on it. These guys actually found the real problem — failed flashing at a parapet wall — and fixed it permanently."

— Robert Hargrove
