Roofing Layer Materials

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.

Roofing layer materials.

A two layer torch down roof consists of one base sheet and one smooth cap sheet. You see them right at the roof s top. On the plus side bitumen does have one of the lowest price tags of all the flat roof materials. The roof is a system composed of layers of different materials that work together to keep wind and weather out of your home.

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. 3 tabs are less expensive but also less durable have lower wind resistance and have a flatter appearance. For roofs with a 3 in 12 pitch or less tar and gravel bitumen roll roofing or even metal sheet roofs work well. It is a waterproofing layer made of regular felt stacked above the solid decking board and then completely covered by the shingles or other roofing materials.

There are two different types of torch down roofing systems. We basically have 5 roofing materials types that are common at the moment. A three layer torch down roof features the same base and cap sheets as well as an additional cap sheet with a granulated surface. The five main types of roofing materials are asphalt shingles cedar shakes concrete or ceramic tiles metal sheets and rubber used for flat roofs.

This is where most of the homeowners will remain focused on materials colors and styles. Your roof type dictates what roofing material you can select. Decking wood sheathing the decking is the base on which everything else is laid. The asphalt then seals up to prevent any holes that stuff like water could get through.

Shingles are the element that most homeowners are familiar with as it is the layer you can see from the outside of your home and it is an important aesthetic aspect. Asphalt shingles come in two major types 3 tab and architectural. Being made of synthetic rubber or polymer they are flexible and elastic and can handle temperature changes and some impact types better than built up roofs. 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.

Each layer has a specific purpose that when combined with the other components provides protection to your home.
