Replacing a roof in cold climates is possible, but it requires some changes to common practices. If the temperature drops below freezing, frost, ice and snow become a safety factor that must be taken into account. Homeowners in New England often ask if they can replace their roof in winter, and the answer is yes. However, it's important to use the right technique from start to finish to ensure that the roof works optimally.
When installing asphalt shingles in winter, most manufacturers require a specialized adhesive that is manually applied to each tile for temperatures below 40°F (4°C). If the tiles are placed below 40° without the specialized adhesive, the warranty may be voided. To ensure that your roof lasts for many years, it's best to work with a company that takes the time to hand-seal each tile. Emergency repair services such as flood and water damage in the basement, emergency roof repair, emergency plumbing repair, damage from fallen trees, installation of new roofs, repair and installation of cladding, restoration of smoke and fire damage, repair of storm damage, and repair of water and ice dams can all be done in winter.
The Asphalt Roof Manufacturers Association (ARMA) warns that even on a freshly cleaned roof there can be an almost invisible accumulation of ice or frost on the surface of the roof or shingles which can make work extremely dangerous. An experienced roofing contractor will work with you to install your roof and protect your home as soon as possible. When done correctly by experienced professionals, it can be successfully roofed in winter. It's important to note that roof activity can break the shingles' sealant bond, so be prepared to hand seal shingles that are coming off the roof.
During the winter, a professional roofing contractor may choose to hand-seal shingles with approved roofing asphalt cement or other adhesives provided by the manufacturer. It's also important to work with a roofing contractor that only uses experienced professionals.
