Asphalt shingle roofs are widespread and this type of pavement is one of the oldest. Over time, the composition of an asphalt shingle has evolved significantly and has been enhanced through science and technology to become a product known for its longevity.
THE TWO ASPHALT SHINGLE VARIETIES
Asphalt shingle is available in two varieties that are the so-called traditional organic shingle and fiberglass shingle.
The oldest shingle is the organic shingle made of recycled paper reinforcement that has been dipped into hot asphalt. This technique allows the coating to have a certain flexibility which makes its installation easier and more feasible during cold weather. Thanks to its heavy weight, the organic shingle is also known to be very resistant to bad weather such as wind or rain and therefore also to rips. It is recommended by roofers to people who want a product resistant to changes in temperature and extreme climates.
More recently, the fiberglass shingle is lighter than the organic shingle because of its composition with less asphalt. Its frame consists of three layers, one in fiberglass that replaces cellulose, one in asphalt and one in superimposed granules. In addition to being lighter than its predecessor, it is also less expensive and is particularly appreciated for its increased heat resistance as well as the lifting of shingle legs in winter.
SPECIFIC CHARACTERISTICS OF ASPHALT SHINGLE
Asphalt shingles are composed of different layers that each has a specific role in the protection of a roof. We first find the surface layer of granules which is composed of rhyolite and basalt. It is primarily used to protect shingles from UV rays, to keep freshness on the roof and to prevent the installation of mold. Then comes the layer of asphalt that seals and waterproofs the shingle to protect the roof from bad weather such as wind and rain. This layer will determine the weight of the shingles. The third layer is the so-called reinforcing layer which can vary depending on the two available varieties and will determine the quality of the shingles. Because it serves as a frame, it is essential so that all layers hold together and must be as stable and resistant as possible. Finally, the last layer consists of an adhesive tape and a nailing tape. The first is activated by heat and it serves to adhere all shingles between them while the second can be nailed. It is this combination that makes the asphalt shingle resistant.
SUMMARY OF THE ADVANTAGES OF ASPHALT SHINGLE ROOF
Good value for money: asphalt roofing is appreciated and preferred by homeowners who want to protect their buildings from external elements at a lower cost. It is indeed of a lower cost than the other coatings.
High availability in the market: Both types of asphalt shingles are found in almost all retailers and roofers in different shapes and colors as needed.
Easy installation: By taking all the building’s features into account, a team of roofers can install asphalt shingles quickly and safely.
Simple maintenance: Asphalt shingle maintenance requires a visual inspection every two or three years except in severe weather where it is recommended to quickly check the condition of the roof.
