SPF Among Top 5 Best Sustainable Roofing Materials

Posted by Nicole Gale on Tue, Jan 17, 2023 @ 12:07 PM

SPF Graphic3Spray Polyurethane Foam or SPF is not new to the roofing industry. SPF has been around for 60 plus years with excellent long-term performance capabilities. Building Enclosure Magazine named SPF one of the top 5 best sustainable roofing materials to consider for your roof. The article states, "No other roofing material has the combination of strength, formability, seamlessness and insulating value provided by spray polyurethane foam."

National Coatings agrees with this statement 100%. Studies have shown the AcryShield® SPF Roofing System has performance properties in year 15 that are equivalent to the initial installation - 15 years later the roof is still providing the same amount of strength, durability, insulation and waterproofing capabilities as it did on day 1! How's that for long-term performance!

Polyurethane Foam

For flat roofs, spray polyurethane foam is an excellent option to consider. It consists of two components (resin and polyisocyanurate) joined together with heat and pressure, which react to rise and form a solid surface. Foam has a number of distinct advantages. It is an insulating material, serves as soundproofing, adds rigidity to a structure, is lightweight and very durable. Foam has been used in roofing applications since the 1960s.

Since it is a seamless product, maintenance is fairly simple. A utility knife and a tube of caulk will serve to address most issues that might arise with a foam roof.

Polyurethane foam has one distinct disadvantage-it will break down over time when exposed to the sun. This is overcome by coating the roof with an elastomeric acrylic, silicone or polyurea, all of which block ultraviolet rays from getting at the foam. The coatings can be used to add a variety of colors to the roof system, although the lighter colors tend to add the most to the insulating value of the roof system.

Polyurethane foam can be installed to any thickness in a series of passes called "lifts." This puts insulation on the outside of the building, blocking heat or cold from passing through to the structure beneath, and vice-versa. No other roofing material has the combination of strength, formability, seamlessness and insulating value provided by spray polyurethane foam.

As society becomes more environmentally-conscious, architects and developers are converting to more "green" products for construction purposes. For more information about "green" roofing materials, be sure to reach out to your local roofing expert.
