Roofing Projects in Hot Weather

Scarring

• A common type of roofing material is the basic asphalt shingle. These shingles do not always respond well to hot temperatures. Specifically, the granules on the surface of the shingles may lose their bonding qualities under intense heat. Walking on the shingles or handling them roughly can then result in lost or shifted granules, a problem known as scarring. This is one reason that hot climates are more suitable for alternative materials, such as concrete or clay tile.

Rain

• Rain may not be a problem you associate with hot weather, but in many climates the two are closely connected. Summer heat is often a precursor to thunderstorms in many parts of the United States. Installing roofing in this heat can lead to problems with rain several hours later, even if you manage to cover the roof with tarps. The weight of the water, the effects of the moisture and problems with wind can all damage a vulnerable roof. It is best to wait until the weather forecast is clear and the heat has died down rather than rush a roofing project.

Heat Exhaustion

• When it comes to labor, heat exhaustion can be a real issue on roofing projects in high temperatures. There is no shade on a roof or a reliable source of drinking water, and to compound the problem, many roofing materials reflect heat directly back onto the workers. These factors combine to make heat exhaustion a dangerous side effect of rushed roofing projects. Proper safety procedures, breaks and hydration are all necessary for roofing projects in hot weather.

Hot Weather Roofing

• If you live in an area that experiences high temperatures frequently, you should choose your roofing to match the climate. Clay tiles are used because they are not easily damaged by fire, let alone heat from the sun, but they also lack reflective capabilities. Metal roofing is more expensive but comes with coatings that reflect light back and keep buildings cool. Fiber cement or concrete tiles may be a feasible compromise between the two materials.
