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

Hail Damage Susceptibility Factors


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 materialSPF is a thermal, air moisture barrier all in one material

- SPF easy to repair and sustainable


- SPF is classified by FIMA to be used in Flood zones

SPF and Hurricanes

• SPF Roof & Wall Performance Facts

- Closed-cell foam increases racking strength 300-400 percent g g paccording to NAHB in wall applications

- SPF roofs resist progressive peeling failure due to being monolithic and fully adheredmonolithic 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 f i i th t th t i i di t d- SPF roofs are unique in that they are not in immediate danger of leaking after severe weather damage according to a survey sponsored by the National Roofing Foundation

• Factory Mutual Global roof wind testing showed similar results over concrete, metal, and wood decks

• SPF offers increased resistance to hail flying debris orFactory 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
