When it comes to low-slope roofing systems, the use of Sprayed Polyurethane Foam (SPF) can be the most robust solution for your commercial or home’s roofing. In the following section, we’ll cover what SPF roofing entails and its features. Here’s what you need to know about spray foam roofing:
Sprayed polyurethane foam in a nutshell
As mentioned, sprayed polyurethane foam is ideal for low-slope roofing systems. Also known as spray foam roofing, SPF is a two-part liquid sprayed so that it can form into a foam. When applied, it expands 30 times its volume to create a seamless, lightweight roof surface. It has stable, robust adhesion to a variety of substrates, which include built-up roofing (BUR), clay and concrete tile, shingles, metal, wood, and concrete. It serves to add weight and slope, which is used to recover existing roof systems.
Use of SPF for the roofing system
SPF roofing system can be used for various solutions to your building’s or home’s toughest challenges. You can use SPF for the following purposes:
• When additional insulation is desired.
• When the roof is exposed to severe weather environment.
• When the roof deck has an unusual shape or configuration.
• When the roof substrate has many penetrations.
• When a slope is required to provide positive drainage.
• When lightweight materials are required.
• When it is desired to keep the existing roof covering.
Features of spray foam roofing
• Surface application: During the surface application, it is required to have a clean surface for proper application. This means that the area must be dry and free of contaminants.
• Life span: SPF is expected to last for up to 50 years, provided that it receives constant repair and maintenance. It has been utilized as a roofing and insulation material over the years. In fact, various studies confirm and uphold the SPF’s dependability, durability, and cost-efficiency.
• R-value: SPF has an R-value of 6.1 per one-inch thickness. This allows you to provide more thermal resistance using less material, unlike other types of roofing insulation. It is also energy-efficient, saving up to 30 percent as compared to other roofing solutions.
• Energy Reduction: This is one great feature of the SPF roofing. It can significantly reduce energy consumption because:
• It has a high R-value per inch.
• It gets rid of air infiltration by providing a continuous air barrier.
• It prevents moisture infiltration.
• It reduces convective currents in walls and attics.
• It prevents wind washing.
• It creates the ideal environment for a proper ventilation system.
• It minimizes dew point problems and condensation.
• It avoids thermal bridging.
• It resists heat movement in all directions.
• Maintenance: Maintenance is required for the SPF system to increase its durability. It needs to be inspected twice a year to examine for possible dents, cracks, punctures from dropped tools, and wind-driven debris. When discovered, they can be repaired with an elastomeric sealant compatible with the SPF and coating system. In most cases, recoating is done every 10 to 15 years to extend the service life of the SPF roof system.
