On the market today are two types of asphalt shingles used in residential and commercial roofing: organic and fiberglass. Organic shingles are typically made from paper, often waste paper that is saturated with asphalt. By saturating the paper with asphalt the shingle becomes waterproof. Then, a top coating consisting of adhesive asphalt is applied to the shingles, and the ceramic granules that we associate with asphalt roofing are embedded in the shingle.
In some areas of the country, algae-resistant shingles are needed. In this case, some of the granules contain leachable paint that is coated—this is designed to prevent discoloration rom algae.
Alternatively, fiberglass shingles are created with a base layer of glass fiber. Then, the base layer is coated with asphalt, making it waterproof. Many homeowners appreciate that fiberglass shingles have a high fire resistance rating because the fiberglass materials tend to resist fire better than some of the other materials that make up asphalt shingles.
Shingle durability is determined by warranted life
The life of shingles varies by materials. Shingle durability is determined by its warranted life. Warranted life typically ranges from 20 years to 50 years. Organic shingles are known for being very durable because they are difficult to tear.
Asphalt shingles are extremely durable, especially in colder climates
Residential roofing experts at Triad Installations in Greensboro, NC, say that asphalt shingles typically last longer in colder climates. Maintenance, as well as proper ventilation, is known to extend the life of an asphalt roof. Experts also say that it is important that asphalt shingles are not applied when the temperature is less than 50 degrees Fahrenheit. This is because each asphalt shingle has to seal to the layer below it—this cannot happen if the temperature is less than 50 degrees when the shingles are installed.
Know when you roof needs to be replaced
While asphalt roofing is known to be long lasting, it will not last forever. Over time, the sun in Greensboro NC can cause the shingles to weaken. As rain falls, the shingles continue to weaken; this is especially true along eves and complex rooflines because more water flows in these areas. Eventually, shingles may shrink, which exposes nail heads under each shingle flap. When this happens, the shingles can start to tear. It is best to let your trustworthy roofers at Triad Installations replace your residential roofing before it gets to this point; once the nail heads are exposed, moisture can seep into the building, rooting the structure. There can also be moisture damage inside the home.
