Cold weather roof installations
Is it acceptable to install a roof in cold weather? The quick answer is yes. However, the roof shingles need warm weather to seal. There is a “tar line” on all shingles that when heated will seal to the shingle below it. This means the roof essentially becomes a solid sealed surface. The only issue that may arise if the shingles do not seal due to cold weather is “shingle blow off.” High winds could potentially blow shingles off the roof. However, proper nailing will make this highly unlikely. One exception is that low slope roof materials generally require the temperature to be a minimum of 50 degrees. Theses materials are not nailed and need to seal in order to protect the roof and home from water infiltration.
