Why You Should Consider a Foam Roofing System

Foam Roofing System

What’s durable, lightweight and provides seamless protection? A foam roof, of course. Among its benefits, foam offers durability, weatherproofing, and improved energy efficiency in the home. Spray polyurethane foam (SPF), starts as a liquid that is sprayed onto roof base and quickly grows to many times the size of its original thickness. As it spreads, it fills cracks and crevices and creates an airtight and watertight seal around vents, pipes, and edges. This wonderfully waterproof roof protects against many elements, including high winds.

How It Works

The foam is created when the spray gun trigger is depressed and two liquids, stored separately, are combined as they leave the gun. The chemical reaction of the liquids to each other creates the foam. The foam expands to a size that is 20 times bigger than its liquid size and creates a dense surface that instantly sticks to the roof. The new foam surface provides a continuous, no-gap insulation rating of R6.5 to R7.

By limiting heat penetration, the foam roof increases the building’s overall energy efficiency by up to 30 percent or more. With savings like that, your foam roof will pay for itself in just a few years by offsetting your heating and cooling bills. In regions with extreme heat or cold, you’ll save even more.

Benefits of an SPF Roof System

If you’re tired of repairing the roof, consider the many benefits of a foam roof, including:

  •  Creates a solid, leak-proof seal that covers the entire roof
  •  It’s a self-flashing system with no joints, fasteners, cracks or transitions that     can begin to leak
  •  High insulation value of R6.5 to R7, resulting in considerable energy savings
  •  Strong adhesion with existing roof and great resistance to wind uplift

Low-Maintenance Foam Roofs

A spray foam roof requires little maintenance and stands up to all types of weather. Harsh UV rays can damage the foam over time and cause it to deteriorate. This problem is easily solved, however, with an application of a silicon top coat that lasts 15-20 year.

You should clean the roof occasionally, which gives you a chance to inspect the roof for any damage. Cracks are easy to fill with a silicone caulk. When needed, a new silicon top coat can be applied to the foam and your roof should be good for another 15-20 years. The foam itself typically lasts the entire life of the building itself.

Foam Offers Flexibility

Need to replace your roof? Spray polyurethane foam is a great alternative to other roofing materials, particularly for those that are more complicated than your roof. Due to its flexibility, foam is especially handy for use on odd-shaped or multi-level roofs.

It also mitigates; thermal shock, which can damage roofing systems through rapid expansion and contraction. For example, on a sweltering hot day in the Sonoran desert, a large and quick-moving storm can cause sudden and large drops in the outside temperature, which creates stress on a roofing system.

Adaptable to almost all types of roofs, foam has been growing in popularity as a roofing material over the past decade. For homeowners and business owners too, low maintenance, energy savings, and durability make foam a definite contender when you’re ready for a new foam roofing system.
