In addition to the extreme temperatures in a given season, the surface must also withstand all forms of precipitation, including wind, rain, ice, snow, sleet and hail. During hurricane season especially, sometimes a combination of these elements can cause significant damage.
Under such conditions, any given roof may be subject to failure if it is not receiving the proper maintenance on a regular basis.
For roofers, working on a roof can also be highly dependent on the weather. If the temperature is too hot, certain repairs such as coatings, slate and shingle repairs cannot effectively be performed because the roof surface will not respond well under the high temperatures. Likewise, some roofing materials can be extremely brittle and easily damaged when cold.
