Icy winter temperatures complicate roofing, paint, plaster/stucco, and masonry projects. The materials involved in these jobs are all sensitive to cold weather, and their integrity is critical for success in winter construction. Roofing season is too short to be hindered by the cold. In addition, the manpower you have is greatly affected by the cold. From cold weather roof repair to full jobs, take the time to prepare your site and keep roofing materials warm with a box heater to ensure smooth operations for all.
Almost all types of roofing material use adhesive during the installation process, and almost all adhesives need warm temperatures or a heat source to properly cure and fasten. Without proper fastening, the roof will fail. Added effort and expense are required to apply these materials in cold winter weather. In addition, tools used can be greatly affected by the cold temperatures. Air compressors and nail guns, when compressing and releasing the air in your system, humidity will turn into water and then ice. Ice will reduce/inhibit the airflow from device to roofer. Nails need to be installed flush with the shingle, and in the situation described here, it is likely that nails will be under driven—resulting in shoddy work. Cold weather roofing requires extra attention from the roofer in many aspects of the job.
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. 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 applied below 40 degrees without the specialized adhesive, the manufacturer will void any warranty.
Powerblanket Hot Boxes are not your typical construction heater. They save you money by keeping your products from freezing without the risk of overheating. Keeping roofing materials warm is easy with our industrial Hot Box pallet warmer. It is is easily assembled, taken apart, and moved from job to job. Hot boxes are ideal for cold weather storage, freeze protection, transporting, job site heating, remote location use, and winter roofing. Standard Hot Boxes hold product between 100°F and 120°F (38°C and 49°C) –optional adjustable thermostatic controllers allow precise temperature control.
