![]() It requires high temperatures to be pliable enough to install and cure. EPDM is joined together using an extensive amount of adhesive. If shingles are applied below 40° without the specialized adhesive, you risk a voided warranty.ĮPDM (rubber) membrane roofing materials are even more temperature sensitive than asphalt (composition) shingles. If winter installation is unavoidable, most asphalt shingle manufacturers require a specialized adhesive manually applied to each shingle for temperatures below 40° F (4° Celsius). While the installation of shingles in winter is possible with the right prep work and materials, it requires a little more attention. Contractors are more likely to overdrive nails, and foot traffic can erode the protective granular layer quite easily in extremely warm temperatures. Asphalt shingles can become overly pliable and are susceptible to damage during installation. Temperatures warmer than 80° can be problematic in the other direction. When working below 70° F, the adhesive may not reach the ideal elasticity and will not create a perfect seal. ![]() This may mean that your roof install won’t be up to standard and will fail sooner than it should.Ĭracked and broken shingles often lead to water damage, one of the more serious problems with roofs. When roofing in cold weather, you run the risk of materials becoming brittle and breaking. This type of damage may not always be obvious on the surface. The extra weight of snow on a roof may also make it more susceptible to collapses. Snow also makes it difficult to see other dangers like a sky light or damaged areas on the roof. Ice can be difficult to see, and injuries like a slip and fall can happen if extra safety precautions aren’t taken. Slick surfaces are a safety hazard for workers. The potential for voided warranty also increases when the temperature drops below 40° F. You risk a faulty roof install if you do not pay attention to the temperature outside. Many roofing products have adhesive properties that require the sun’s heat for activation. The best temperature range for roof installations is between 70 and 80 degrees Fahrenheit (21-27 degrees Celsius), but when is it too cold to roof? It really is too cold when temperatures drop below 40° F (4° C). Roofers must find solutions to continue their job even with problematic weather conditions. This is especially true during winter months, which brings even more challenges like freezing temperatures and snow. ![]() ![]() Unfortunately, perfect temperatures and clear skies aren’t the norm every day of the year for most states. When is it too cold to roof? An ideal day for roofing would be nice and warm, with no chance of rain or wind. ![]()
