How does SPF roofing hold up to tornado winds?
Memorial Day kickstarted tornado season across the Midwest and this year looks to be a doozy!

No home can fully withstand the force of a tornado, but high storm winds leading to tornadoes can cause roof damage. Pre-tornado winds can gust up to 40 m.p.h. and cause wind lift on building roofs that leave substantial damage. With Missouri parked inside Tornado Alley, there’s no debate that it’s a matter of when, not if, a twister tails its way down to the Show Me state. Weather bracing for roofing structures are excellent solutions, but how can SPF roofing help secure your roof against severe winds?
When SPF roofing is installed, it’s applied through a dual-compound chemical bonding process. Two large drums feed isocyanate and polyol fiber into an applicator. The installer sprays the foam into place and that’s the first time the two compounds come into contact. This causes an immediate chemical reaction that starts the foam’s expansion process. SPF spreads as it expands up to thirty times in density and adheres to all surfaces that it contacts.
SPF roofing is designed to create a monolithic covering over any commercial roof surface. This bonds and strengthens the roofing substrate to the building structure. The end result is a reinforced roofing bond that helps reduce wind lift and creates a cohesive force against severe weather.
Again, no roof can be guaranteed against tornado damage or even extreme wind speeds, but SPF gives your commercial roof a fighting chance against the wild Midwestern storms. SPF roofing can help reduce your energy costs and comes with an unmatched life-cycle to protect your roof for years to come.
