What are the climates and conditions where a sprayed polyurethane roof cannot/should not be applied?
Spray foam roofs are just like all other roof systems; they need to be applied to a clean and dry substrate. Spray foam roofs can be installed in most regions of the world.When applying spray foam to roofs, it is recommended for best results that the ambient air temperatures range between 40 – 100 degrees F and that wind conditions are less than 12 miles per hour (or 25 miles per hour when wind screens are being used). For best results, it is recommended that humidity levels are below 80% at the point of application. These general rules of thumb are true for most commercial roofing systems, regardless of their type, if you want to follow good, safe roofing practices.
