If SPF Is So Good, Why Is Adoption Slow?
Spray polyurethane foam is a groundbreaking material because it’s the evolution of existing plastics. While it isn’t without its flaws, it’s still a much-capable material with many applications.
Many property owners ask about the sluggish pace of SPF adoption in Canada and other countries. We can attribute them to the following factors, which we base on our experience as applicators.
Fallacy: SPF Is Expensive
It’s true: you can spend much less on modified bitumen or single-ply roofing for commercial roofs than SPF. It costs about $4-$7 per square foot of flat SPF roofing, which means you’re investing.
However, in 5-10 years, you’ll see enormous utility and maintenance savings, allowing your roof to pay for itself in a short period. On the other hand, a little more than a decade is enough for modified bitumen and single-ply roofing materials to fail.
Fallacy: SPF Is a Weak Roofing Material
Both open and closed-cell spray polyurethane foam has the best resilience against high-velocity, sharp missiles, such as hailstones, stones, and branches. On the other hand, EPDM, TPO, and PVC are weak against these same elements. Additionally, wrong-footing can cause bruises and cracks against single-ply membranes.
SPF adoption is slow because most property owners perceive single-ply roofs to have the best durability. However, with an increasing SPF applicator population, many see the better and much more cost-effective alternative.
Fact: SPF is Toxic
Property owners who refuse SPF roofing and exterior cladding often mention toxicity and lung disorders SPF causes. While SPF’s toxicity is a fact, a professional applicator with proper safety equipment is never in peril.
Additionally, tenants and employees won’t have to worry about SPF roofing because roofers test and observe the newly-applied roof after 24-48 hours for use viability. While it’s true stray airborne SPF can damage the lungs, dried SPF is completely harmless and capable of exceptional protection and durability.
Fact: Spray Polyurethane Foam Applicators Are Few
Many professional roofers across Canada and the world have expertise in traditional commercial single-ply and rolled roofing. However, the SPF applicator population will likely increase as property owner demand increases.
With the material’s superior-level capability and dependability, it’s likely to gain traction from numerous property owners with aging roofs. In doing so, the population of SPF applicators will increase in proportion.
Fact: You Can Spray Over Existing Roofs
Your SPF consultant wasn’t kidding after saying you won’t need to tear down your aged low-slope roofing, and their SPF applicators can just spray over it. However, some caveats must exist to make this possible, such as your roofing structure having ample support structures that guarantee top-level performance.
While SPF isn’t heavy, it will still exert some stress against your existing roofing joists, trusses, and support structures. Thankfully, your reliable SPF applicator can advise property owners about repairs and upgrades.
