Complete Guide to Spray Foam Roofing

Spray foam roofing is a widely used roofing technology in Arizona and other hot-weather states due to its insulating properties and durability. The process of spray foam roofing involves spraying liquid polyurethane foam onto the roof surface, which then cures over a short period, leaving a solid material that fully adheres to the roofing.

Spray polyurethane foam (SPF) was first introduced in the 1940s, but it was primarily used for military purposes. Its widespread commercial use began in the 1970s because of its versatility. The rising costs of energy sources increase the need for effective solutions for heat management and, consequently, energy efficiency. 

Spray foam roofing systems provide good insulation, are durable, and easily applied. Read on to learn why spray foam roofing is a wise decision.

Why Consider Spray Foam Roofing

You can spray foam the roofing of your property, whether it’s new or an existing one. The high thermal resistance of polyurethanes sets it apart from other materials. Let’s see why spray foam roofing is the right choice for your Arizona property:

  • Heat resistant: Polyurethane is an insulation material with an exceptionally high R-value per inch, which means that your home will stay cool during heatwaves and extreme climate, which is especially important in the intense heat of Arizona summers. At the same time, it has an extremely low U-value because of its seamless design, preventing heat from penetrating the cracks. 
  • Water resistant: When applied, the foam fills out all cracks, seams, or other structural imperfections, meaning heavy rain cannot penetrate and cause damage. 
  • Durable: Once set, polyurethane becomes solid and thin with an average thickness of 1 inch. However, do not let looks deceive you because it can last for 20 years with proper maintenance. It is more flexible than concrete and metal, meaning it will not crack with the movement of the building. 
  • Sustainable: Spray foam roofing is cost-effective from two perspectives. In the short run, because it is installed on an existing roof, avoiding tear-off costs, and in the long run, because it is durable, renewable, and energy-saving.

The Process of Spray Foam Roofing

If you are interested in this roofing system, the next step is to learn how it’s applied. The procedure is straightforward and takes little time because the foam hardens very quickly. Still, a professional is needed to estimate the amount of foam needed and the right equipment for coating. 

  • Cleaning and repair: First, roofing specialists must thoroughly clean the existing roof structure using a sweeper, a vacuum cleaner, or a pressure washer. Any structural damage has to be repaired, and you may also need to prime the surface to ensure the foam adheres to it perfectly. 
  • Spraying: After the roof is clean and dry, a skilled roofer sprays the polyurethane foam using a specialized machine with a spray gun. During this step, the isocyanate and polyol liquid mix is sprayed using pressure and heat. It expands its size 25 – 30 times, covering the entire roof area, and hardens within a minute. That’s why it requires precision and skill. 
  • Coating: The cured foam is covered with acrylic, silicone, or polyurethane protective coating to ensure waterproofing, fire resistance, and UV protection.
