Cold Weather Install
Winter Cold and Shingle Roof Installation Facts
Winter can seem like an unlikely time for construction work. Winter is often seen as too cold or too wet for any type of exterior installation. However, temperature has little effect on experienced crews who know how to protect the property from damaging snow and water. You may prefer to sit by a cozy fire and roast chestnuts, but the cold should not stop you from needed exterior work.
Experienced roofers can work through the winter
Most roofing contractors agree that cold weather installation of shingles is more difficult and time consuming than spring or summer, but they also agree that it can be done with the proper care and consideration. Many of our customers have brought up valid concerns about asphalt shingle installation in cold weather. While there are many known problems, but if you understand the issues and how to deal with them, then there will be no problems to deal with later.
Asphalt shingles become brittle when cold and can't be installed.
Shingles do get stiff and brittle at very cold temperatures. However, experts agree that temperatures would have to be below zero degrees Fahrenheit before there are handling concerns. Even at subzero temperatures, shingles can still be nailed through without cracking or breakage. However, care must be used in order to not pry or bend cold shingles.
Asphalt shingles can't bond properly in cold temperatures.
Shingles have adhesive strips on the back that bond it to the shingle below it. This bonding material needs heat to completely cure. Without a full bond, high winds can easily lift the shingles and cause damage that needs repair. However, even in the winter, the sun should have enough exposure to bond the shingles over several days. Also, beads of additional adhesive may be applied to each shingle by hand during installation to make sure the bond is made quickly. In Georgia, it is not usually necessary to use the additional adhesive because of the mild winters compared to the northern states. However, a good roofing company would have to make a judgment call based on the circumstances and back up their installation methods with a good roof warranty.
