So maybe an ambient temperature of about 80 degrees is a rough estimate. Multi-plot pedestrian Roofer in Hanahan SC Roof pitch for walking or not walkingMore results from forum, nachi, org. A cold tile is quite brittle. If you have to lift a corner, do it gently, as while it is cold it could easily break. Room-temperature tile has reasonable flexibility, but you can go too far and fracture the fiber even if you don't break it, permanently weakening it.
When it's very hot, asphalt shingles are extremely flexible and can be handled safely. 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. There is no doubt that there is a point where, in general, the roof should not be built when temperatures drop below above 40°F. It's best to do the roofing project in spring, summer, or early fall, when the days are long and the temperatures range from 70°F to 80°F.
So now you might be wondering, what are the reasons why temperature greatly 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. With that said, let's take a closer look at how and why roof temperature can affect the overall quality of roofing work.
Roofing contractors recommend scheduling roof installations, repairs, or replacements during seasons when average temperatures exceed 50°F and conditions are generally mild and dry.
It is possible to install roofs during the winter, but it is extremely difficult due to low temperatures. Professional roofing contractors generally agree that while roofing projects can be done at any temperature, most experts advise against roofing when the temperature drops below 40 degrees or rises above 85 degrees. Ideally, the temperature and best conditions for working on a roofing project or installation should be around 55 degrees, with moderate humidity, low speed winds and no rain.Anyway, people climb onto roofs and walk everywhere, regardless of the damage they cause, until they're going to sell and I arrive. Once temperatures fall below 40°F, asphalt roof tiles begin to lose their flexibility and become more brittle.
