What temperature is too cold to install asphalt shingles?
The NRCA has not set any specific guidelines for the temperatures for installing asphalt shingles.
While there are not any regulations, it is recommended that your contractor use quarter-sized dabs of adhesive if the weather is not hot enough for the self-sealing strips to adhere to each other. He must also make sure that he is very careful with the shingles, as they can become quite brittle in the cold.
