SPF and elastomeric roof coatings can be installed in all geographic areas of the United States. Most applications occur when the target temperatures are 45°F to a very warm 120°F. Considering that solar gain on a dark surface will raise the temperature by as much as 35 degrees during a sunny day, this provides a wide temperature range for installations. Although it is true that moisture— such as rain, frost, dew, and snow— on the substrate will prohibit the application of foam or coatings; still, there are ways around this application barrier. The SPF industry has established guidelines stating that spray foam is not to be applied when the temperature is within five degrees of the current dew point. Applicators typically monitor the weather conditions through weather data and by using handheld electronic measurement tools.
SPF roofs can only be installed during very limited conditions.
