The word roofing is derived from Latin – “roof,” and “house” – “a roof.” A roof is actually the covering most people think of when they think of houses, but a roofing job can also consist of other structures like a gable roof, pitched roof, flat roof, sloped roof, and many others. A roof isn’t simply a frame around a structure – it’s usually comprised of shingles, insulation, a roof covering, a vapor barrier, and more. Roofing is one of those things that’s usually easiest to understand and describe, but there are several layers and subtleties that make roofs very complicated and difficult to manage.
Roofing – How to Prevent Leaks and Sealcoats
Roofing refers to the action of driving or pushing materials such as slate, gypsum, bitumen, cement, and metal into a slot made to accept the materials. The slot then fills with mortar and the roofing is created, which consists of several layers. The first layer of a new roof needs to be tightly packed with gravel and silt, which prevent water from penetrating and leaking onto the next layers. The layers themselves keep moisture in, so that rainwater can’t seep between. The third layer, a re-roofing layer, is added to strengthen the roof and provide additional protection.
Although there are three layers of materials, not all roofs have them. Flat roofs, such as clay tiles or asphalt shingles, typically only have two layers. Single ply roofs have three layers. In order to get an earth roof, you need to add additional insulation and, often, metal flashing. Lastly, there are a number of other materials that can be used for roofing. The three layers are pretty much the basics, but there are many other options as well.
