Spray Foam Roofing

What is (SPF) Spray Foam Roofing?

Spray foam roofing is a watertight roofing system that has three parts:

  • Spray polyurethane foam (SPF) is sprayed over existing roof or decking.
  • Silicone coating is installed in two coats: A base coat and a top coat.
  • Granules which can be optional.

The polyurethane foam is produced by combining and heating two chemicals. These chemicals are pumped from a truck, transferred through a heated hose, and then sprayed onto an existing roof. The foam increases in thickness by 30x, reaching an average height of around 1.5 inches. The spray foam’s height (or thickness) is customized to every roofing system to create a slope for water to run toward drains.

Spray foam gets damaged from UV rays, so a thin layer of silicone coating is installed over the foam to protect it. The thickness of the silicone coating is usually around 20 – 30 mils. The silicone coating is installed in two separate coats, where the topcoat can be embedded with granules. Granules are suggested for added strength, durability, UV resistance and also to create traction for safe walking. Granules can also be used to create a decorative finish

What we do

Step 1: Preparation and Cleaning
We thoroughly clean the roof surface to remove dirt, debris, and any existing coatings.

We then repair any damage to the roof structure, such as leaks or cracks.

 
Step 2: Primer Application
We apply a specialized roofing primer to the cleaned surface to ensure proper adhesion of the foam and create a uniform base.
 
We allow the primer to dry completely according to manufacturer instructions.
 
 
Step 3: Polyurethane Foam Application
We spray the polyurethane foam in a continuous, even layer onto the primed roof surface.
 
We will apply the foam in multiple passes to achieve the desired thickness, typically between 1 and 3 inches.
 
Insulation: If additional insulation is needed, consider incorporating a layer of insulation beneath the foam or within the foam itself.
 
 
Step 4: Base Acrylic Coat
We apply a base acrylic coating to protect the foam from UV rays, weathering, and foot traffic.
 
The base coat provides a durable foundation for the top coat and helps to ensure long-term performance.
 

Step 5: Top Acrylic Coat
 
We apply a top acrylic coat to provide additional protection and enhance the appearance of the roof.
 
The top coat can be customized with various colors and finishes to match your building’s aesthetic.
 
 
Step 6: Granules (Optional)
We can add roofing granules for a decorative finish or additional protection.
 

Benefits of SPF


Energy Efficiency: Reduces energy consumption by providing excellent insulation, leading to lower heating and cooling costs.
 
Durability: Offers long-lasting protection against harsh weather conditions, including wind, rain, and hail.
 
Waterproofing: Creates a seamless, waterproof barrier, preventing leaks and moisture damage.
 
Lightweight: Reduces the load on the building’s structure, potentially extending its lifespan.
 
Versatility: Can be customized with various coatings and finishes to match your building’s aesthetic.
 
Cost-Effective: Can provide long-term savings due to reduced maintenance and energy costs.
 
Environmental Benefits: May contribute to energy conservation
