Spray Polyurethane Foam (SPF)

Spray Polyurethane Foam (SPF)

Spray Polyurethane Foam is a low-slope roofing option that insulates and waterproofs in a single application. Liquid components combine at the nozzle and expand into a continuous foam layer that seals across seams, penetrations, and odd geometry that flat roofs tend to collect. It is typically considered on aging built-up or modified bitumen roofs, or wherever a flat deck needs both a thermal boost and a fresh water barrier without a full tear-off.

Checking What's Underneath First

Foam only performs as well as the deck beneath it, so we look before we spray.

• Core Sampling Tools — A small test cut on a flat roof that shows every layer, so a recommendation is based on what is actually up there.
• Moisture Meters — Direct readings through decking and insulation that show how far water has traveled under the surface.
• Handheld Infrared Cameras — Thermal scanning inside and out that traces a leak back to where the water actually enters the assembly.
• Drones with Thermal & High-Res Cameras — Aerial thermal imaging that finds wet insulation and storm damage without anyone stepping on a fragile roof.

Applying and Documenting the Foam

• Airless Sprayers, Rollers & Squeegees — Coatings applied at the mil thickness the system calls for, over the foam once it has cured.
• Photo Documentation Apps (CompanyCam) — Time-stamped, location-tagged photos of every stage of your job, shared straight to you.
