Winter Roofing and Powerblanket Hot Boxes
Winter roofing is not at the top of anyone’s winter recreation list; however, it becomes essential when there is damage to a roof.
Almost all types of roofing material utilize adhesive that requires warm temperatures during the installation process. These adhesives require warm temperatures (heat source) to properly cure and fasten. Without proper fastening, a roof will often fail quickly, if not immediately. In the summer, the sun’s heat will properly adhere most roofing materials: asphalt shingle, EPDM (rubber) single-ply membrane, roll roofing, peel and stick roofing, and modified bitumen. Added effort and expense are required to apply these materials in cold winter weather.
The ideal temperature range to install asphalt shingles is between 70 and 80 degrees Fahrenheit (21 and 27 degrees Celsius). Colder than 70 degrees and the adhesive will not reach the ideal elasticity and will not create a perfect seal. When temperatures are warmer than 80 degrees, asphalt shingles can become overly pliable and are susceptible to damage during installation.
If winter installation is unavoidable, most asphalt shingle manufacturers require that a specialized adhesive is manually applied to each shingle for temperatures below 40 degrees Fahrenheit (4 degrees Celsius). If shingles are applied below 40 degrees without the specialized adhesive, you run the risk of voiding the warranty.
EPDM (rubber) membrane roofing is even more temperature sensitive than asphalt (composition) shingles. EPDM is joined together using an extensive amount of adhesive, and the adhesive must have high temperatures to be pliable enough to install and cure. Very thick and hard to work with even at high temperatures, manufacturers recommend temperatures be above 45 degrees Fahrenheit (7 degrees Celsius) for installation. That recommended temperature is not very practical unless you have a warm storage area available to keep the adhesive warm until the moment it is used.
Powerblanket Hot Boxes
