The five main types of roofing materials are asphalt shingles cedar shakes concrete or ceramic tiles metal sheets and rubber used for flat roofs. On the plus side bitumen does have one of the lowest price tags of all the flat roof materials. For roofs with a 3 in 12 pitch or less tar and gravel bitumen roll roofing or even metal sheet roofs work well. Flat or nearly flat roofs must be covered with built up roofs such as tar and gravel or more modern counterparts to keep water out.

These roofs are installed as thin sheet materials 0 030 30 mils to 0 060 inches 60 mils thick and are applied to the roof in a single layer. A two layer torch down roof consists of one base sheet and one smooth cap sheet. 3 tabs are less expensive but also less durable have lower wind resistance and have a flatter appearance. Ridge vents are at the top of your roof covered by roofing material but with a gap designed to allow warm moist air to escape from the attic.

A three layer torch down roof features the same base and cap sheets as well as an additional cap sheet with a granulated surface. Roof covering typically of flat and rectangular shapes and made of various materials such as slate wood flagstone plastic metal and composite materials. First on our list is modified bitumen which involves using an asphalt base that comes in multiple layers with each layer getting welded on to the roof.
