Roof shingles are fundamentally the roof casing that consists of individual overlapping elements. These elements are usually plane rectangular shapes that are placed in rows with no overlapping of side edges. There are various types of shingles available in the market and made by different materials like, cement, asphalt, wood or slate. Asphalt roof shingles are one of the most generally demanded roofing covers for the reason that they are comparatively low-priced and practically simple to set up.

There are two types of asphalt roof shingles commonly used, one is organic and the second is fiberglass or glass fiber. The firstly mentioned type is organic and these are made through waste paper flooded using asphalt with it and are water defiant. Although these are water resistant but still moss could develop on these but at slow pace. Moss likes to survive on any garbage on the roof, normally five (5) to (10) years warranty is offered by many manufactures in opposition to algae growth.

Another characteristic of organic shingles is that these can grasp forty percent (40%) extra asphalt in a hundred square feet as compared to the fiberglass shingles. Another truth is that these become less environment friendly due to having extra asphalt in them. Organic shingles also have another hazard of being explosive due to their nature of construction which is paper based. Therefore shingle durability should also be ranked by its warranted life.

Fiberglass shingles contain a base covering of glass fiber reinforcing mat and after this it is covered with asphalt which helps the fiberglass shingle to become waterproof. Fiberglass mat is improved flame-retardant to a large extent if compared with the organic or paper mats. Another aspect of these asphalt shingles also needed to be noted that these gets a longer life in cooler climate as compared to the hotter environments. Thermal shock is something that is more destructive to shingles, destruction to shingles starts when the temperature changes significantly in a very little era of time. One more factor that affects asphalt shingle is roofs exposure to air. Proper exposure to air has been acknowledged to make longer the service life of a roof.
