If you have a low-slop or flat roof, you may be using spray foam for its roofing material. Consumers love spray foam because it is energy efficient, which will save them money on their energy bills. A concern about this material is if it will be able to withstand extreme weather conditions, or if the energy savings will be offset by the cost to repair the roof down the road. Here is what you need to know about spray foam and 3 weather conditions.
High Winds
Spray foam roofing has a huge advantage in situations where it experiences high winds. This is because the material cures as one large piece of foam. It does not have any seams or edges. It's very important when dealing with high winds.
You may not realize that a building that uses spray foam roofing will become more structurally sound, because the roofing material is an additional piece that holds the structure together. It will give the building additional resistance to extreme winds. The roofing material is also less susceptible to damage, because it will be difficult for wind to get under a portion of the material and lift it away. It will be resistant to uplift from the wind, making it capable of resisting wind damage.
Storms
Many people have a misconception about spray foam roofing, since they think the material is absorbent and soft. It may cause people to think that it won't stay dry in wet conditions.
Spray foam roofing is waterproof, all thanks to the closed-cells that make up the material. The outside is completely sealed, and water won't be able to get into it. The cells are also a little flexible, which is what will give spray foam a resistance to impact damage. It will bend just enough so that it doesn't fracture due to stress. The coating on the top layer also helps with impact resistance to provide protection to the foam.
Hurricanes
A hurricane combines many aspects of extreme weather. This includes high winds, heavy rain, and impact damage. The additional factor is that a hurricane can bring with it an extreme amount of water, and the spray foam must withstand it without causing a leak.
Spray foam won't have an issue with pooling water, mainly due to the material not having those seams. Water won't be able to get past the foam, so it will stay there until the water evaporates or you clear it out yourself.
