There are many types of roofing materials available on the market. The main options for residential roofing materials are categorized into wood, metal, tile, slate or asphalt shingles. Each material has both advantages and disadvantages. The most widely used roofing materials are metal and asphalt, and it is because of the qualities and advantages they have and offer.
There are several types of materials used in metal roofs although they might look similar. The most frequently used metal roofing material is steel, because it is heavier and sturdier than other metals used in roofing. In order to avoid or prevent corrosion, steel is usually coated with tin; other coatings are applied to steel to enhance its durability and make it look nicer. Other metal roofing material types are aluminum, stainless steel, copper and some alloys, as well. Metal roofing materials are among the most expensive ones.
Asphalt roofing material is created by using composition shingles or fiberglass shingles. When the matrix is ready, it is dipped into asphalt and then the shingles are made. Asphalt roofing material is widespread and appears on many residential buildings. The reason for its popularity is the fact that asphalt roofing material combines low costs with a nice appearance.
Another aspect related to roofing material choice refers to the kind of roof to be built. Thus the inclination or flatness of the roof will have a say in deciding which roofing material to use. Thus asphalt and wood shingles, slate, tile and metal are convenient and suitable at slopes of four inches in twelve or steeper,while asphalt roll roofing or membrane roofs will go well with roofs with pitches below three inches per foot.
