Our Attic Insulation Process

Our proven process ensures quality results on every spray foam project.

1

Inspection & Assessment

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.

2

Surface Preparation

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.

3

SPF Application

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.

4

Protective Coating & Cleanup

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.

"Our foam roof had some blistering and a couple of punctures from a maintenance crew walking on it. They repaired everything in one visit — cut out the damaged foam, re-sprayed, and recoated. Good as new."
