When the need arises for a roof replacement, there’s a lot to consider and the decision can easily overwhelm homeowners given all the available options out there. Asphalt shingle roofs have grown in popularity, especially for residential homes, particularly because it presents a cost-effective alternative that doesn’t skimp on quality and durability.
1. It is derived from petroleum
Also known as bitumen, asphalt can appear in liquid or semi-solid form, and is found in natural deposits and or in refined products. The material is largely used for road construction but its waterproofing properties have become particularly sought after in roofing. The black, sticky, potent substance in its natural form is the perfect base to adapt for durability.
2. Two types
The two forms of asphalt shingles is organic and fiberglass. Organic asphalt shingles is made with a base of natural materials like cellulose, wood fibers and waste paper, which is then soaked in asphalt for its waterproofing capabilities, after which a top coat of asphalt is applied. Fiberglass asphalt shingles in turn is made of glass fibers instead of natural materials, following the same process as the organic version. The key difference here is fiberglass’ increased resistance to fire, which organic doesn’t fair well in because of the presence of paper and wood.
Homeowners are spoilt for choice with asphalt shingle roofing. Some of these options include 3-tab, jet, signature cut, Art-Loc, t-lock, tie lock and architectural shingles. Your choice will be determined by the style you’re hoping to achieve for your home as well as that all-important budget factor.
4. The importance of ventilation
One important thing to note is that adequate roof ventilation is a must when installing asphalt shingle roofing. Aside from the fact that good ventilation will increase the lifespan of the shingle roofing, if ventilation is not up to standard, the roof will forfeit its warranty. So be sure to give that a thorough assessment before moving ahead with your asphalt shingle roofing installation.
5. Kind to the environment
Asphalt shingle roofing is kind to the environment on two fronts. First, its ability to reflect heat from the sun, means the materials help regulate internal temperatures of the home, foregoing the need for cooling systems. Second, asphalt shingles can extend their lifetime by being recycled as raw material for new roads, contributing to a circular economy.
