Background on Storm Events and Effects

  • Severe Weather Facts
  • Roofs are primary contributor to disaster-related losses
  • Roofs are primary contributor to disaster-related losses
  • NOAA reports more than 800 tropical storms in past 100 years
  • Roofs, followed by windows and doors are most susceptible

Other vulnerable areas foundation framing and wall

  • Other vulnerable areas, foundation, framing and wall

connections in commercial building

  • U S annual claims for Hail damage average $1 94 Billion
  • U.S. annual claims for Hail damage average $1.94 Billion

Membrane vs. SPF Weather Effects

  • SPF compressive strength 45-50 lbs vs. 20-25 lbs for board stock insulation
  • SPF adds very little weight and adheres well to a variety of substrates
  • SPF is a thermal air moisture barrier all in one material

  • SPF roofs resist progressive peeling failure due to being

monolithic and fully adhered monolithic and fully adhered

  • SPF roofs improve deck attachment and reduce deck failures

in high wind events

  • SPF roofs reduce missile impact damage and leakage

SPF Performance in Adverse Weather

  • SPF is the only roofing system described by NIST officials as

having “sustained the winds [of hurricanes Katrina and Rita] extremely well without blow-off of the SPF or damage to the KEY FINDINGS SOURCE

  • SPF roofing wind uplift resistance exceeded the capacity of UL’s

test equipment over concrete I-990

  • UL also observed that SPF re-roofs applied over traditional roof

  • Factory Mutual Global roof wind testing showed similar results
  • ver concrete, metal, and wood decks
  • SPF offers increased resistance to hail flying debris or

Factory Mutual

  • SPF offers increased resistance to hail, flying debris or

“missiles” [wind-blown projectiles] during high wind events

  • Gouged spray foam roofs can remain without repairs for months

without leaking both during and after severe storms

  • SPF roof systems have a proven track record for protecting

Roofing Industry Educational Institute

SPF roof systems have a proven track record for protecting buildings against severe storms, tornados, and hurricanes

  • SPF is one of the best ways to temporarily repair damaged

roofs – adheres to a broad range of substrates, seals against water inflow, and is easy to transport into storm damaged areas
