Once temperatures drop below 40°F, conditions become too cold to install asphalt shingles effectively. Materials lose flexibility, become brittle and cannot be sealed properly. It's really too cold for roofing in cold climates when temperatures drop below 40° F (4° C). Many roofing materials have adhesive properties that require heat from the sun to be activated.
You can end up with a faulty roof installation if you don't pay attention to the outside temperature. When the temperature drops below 40°F, the chance that the warranty will be canceled increases.

The best temperature range for roof installations is between 21 and 27 degrees Celsius (70 and 80 degrees Fahrenheit), but when is it too cold to roof? It's really too cold when temperatures drop below 40°F (4 °C).
Many roofing products have adhesive properties that require the sun's heat to activate. If you don't pay attention to the outside temperature, you run the risk that the roof installation will be faulty. The possibility of voiding the warranty also increases when the temperature drops below 40°F. The temperature too cold for a roof is 30 degrees Fahrenheit.
Most roofing companies will tell you that they don't install roofs below 40 degrees. This is because asphalt shingles tend to crack below that temperature. Another problem is when the temperature rises. A particular problem faced by contractors is the rapid drying of the adhesive.
It can be difficult to position the tile precisely piece by piece if the joint dries quickly. Shingles can soften and lose their original shape depending on the material you have chosen. It may be more difficult to install if such a thing happens. In addition, heat can alter the shape and edges. This change can cause difficulties in installing them side by side with accuracy and precision.
The best way to avoid this problem is to install roofs at a temperature between 40 and 80 degrees Fahrenheit. The minimum temperature for installing shingles is 40°F. Subzero temperatures prevent roofing materials and adhesive properties from working properly. Herpes zoster loses its elasticity and cutting or nailing nails through it becomes a challenge.
That's why most licensed professionals recommend 40°F as the limit for installing asphalt shingles. Since temperature directly influences the performance of roofing materials, such as asphalt and fiberglass shingles, it is imperative to plan strategically when undertaking a roofing project. To seal eaves, valleys, skylights, ventilation grilles, and plumbing pipes, use membranes for winter weather, instead of using roll-up covers for warm climates, which can be folded or wrinkle when it's cold. Roofing in cold temperatures creates some problems that would not otherwise arise at other times of the year.
Some roofers prefer polymer-modified shingles, which tend to be more flexible in most temperature ranges; however, at some point, cold weather affects even these shingles. People who live in areas with cold winters know that it's best to roof their homes in spring, summer, and early fall. These low temperatures present unique challenges, affecting materials, the safety of the work equipment and, ultimately, the integrity of the roof. So now you might be wondering, what are the reasons why temperature strongly influences the outcome of a roofing project? The short answer is that the properties of roofing materials make them susceptible to physical changes during installation and repair if the ambient temperature is too high or too cold. Ideally, the optimal temperature and conditions for working on a roofing project or installation should be around 55 degrees, with moderate humidity, low speed winds and no rain.
Roofing companies are used to installing roofs during the winter months, especially in colder climates, where temperatures tend to fall below freezing. Installing roofs in cold climates comes with some challenges, but it's still a perfectly suitable season to replace a roof. It is possible to install roofs during the winter, but it is extremely difficult due to low temperatures. According to Roofing Construction & Estimating by Daniel Benn Atcheson, the best temperature for installing asphalt shingles is between 40 and 85 degrees F (4 and 26 degrees C).
Most experienced roofers are comfortable working in very cold temperatures and should have no problem adjusting to winter weather. Roofing materials with EPDM (rubber) membrane are even more sensitive to temperature than asphalt shingles (composite). When it comes to roofing materials, keep in mind that shingles are less flexible in cooler temperatures, so don't store them in places where the beams bend or warp.
