Spray Polyurethane Foam, or SPF, has been the choice roofing system in the country for a long time. This is because SPF Roofing offers an easier way of installing safer, more durable roofing than other systems on the market today.
Easier to Install and Replace than Metal Roofs
True to its name, SPF is installed by spraying the polyurethane foam onto the surface of a roof, whereas metal roofs require numerous metal sheets to be installed individually. The installation process of SPF is simpler and requires less time and manpower than traditional metal roofs.
If a metal roof sustains weather damage or other forms of destruction, it will require time and manpower to replace an entire section of the roof, even if the damage was minimal. With SPF roofing systems, however, the tear-off damage is minimal and only the affected part of the roof will require replacement.
More Flexible and Lightweight than Asphalt Shingles
Asphalt shingles weigh at about 250 pounds per square feet. This is in contrast to lightweight SPF roofing, which weighs only 60 pounds per square feet, almost 3/4ths lighter. Although SPF roofing is much lighter, once it hardens it can offer the same amount of protection as asphalt shingles.
SPF roofing is also much more flexible than asphalt. Shingles made from asphalt become brittle over time and will break if struck by tree branches or under high wind stress. SPF roofing, on the other hand, is flexible enough to withstand the normal contraction and expansion of structures, while being strong enough to withstand severe weather and other external conditions.
Eliminates Leaks Better Than BUR Systems
BUR, or built-up roofing, requires alternating layers of bitumen and a layer of insulating sheets. These sheets are mechanically attached to the roof structure. These mechanical attachments, or open joints, are susceptible to leaks and damages, as they create a seam for moisture to seep into.
SPF roofing systems, however, are seamless. The SPF molds itself to whatever shape of structure it’s applied onto, creating a single, unbroken layer that is more efficient at preventing leaks.
Unlike Single-Ply Roofs, SPF is Renewable
Once single-ply roofs reach the end of their usable life, the entire system must be taken down and replaced. Although single-ply roofing life expectancy can go up to 40 years, this period is significantly reduced when you consider weather damage, structural changes, or other external factors.
SPF roofing systems, on the other hand, can have an indefinite lifespan. Any damage that an SPF roofing system sustains can easily be repaired, and if an entire overhaul is necessary, the application process is much simpler and much cheaper than with other roofing systems. The cost of reapplying SPF roofing is much lower than single-ply or other roofing systems while being more efficient at insulation. This adds up to a more cost-beneficial system.
