But what exactly are asphalt shingles? Asphalt shingles are asphalt-saturated bases made from either organic materials or fiberglass. Organic shingles combine waste paper, asphalt, salt coatings, and ceramic granules. In contrast, the fiberglass shingles are made from glass fiber coated in asphalt and minerals such as mica, schist, quartz, slate, ceramic, or stone. The asphalt and mineral coatings are responsible for the shingles’ waterproof and fireproof features.
Asphalt shingles are commonly cut in the “three-tab” pattern, but they can also be found in many different shapes, styles, and colors.
Asphalt shingles are a popular roofing material for many reasons but are they the best option for you and your home? We unpack some of the advantages and disadvantages of asphalt shingle roofing.
Advantages
Asphalt shingles are by far the most affordable roofing material on the market. They’re quick and easy to install, and when installed correctly and properly maintained, they can last for about 25-30 years.
The shingles are also easy to tear down, repair, or replace if necessary. One thing that makes them affordable is that they don’t require any special tools or accessories to install them, such as roof edges, vent flashings, or wall terminations.
Their versatility opens them up to various shapes, styles, and colors, allowing you to style them as you please for your desired aesthetic. The shingles are water and fireproof, adding extra protection to your home in case of emergencies. They also work well on homes with steep, sloping structures and are compatible with most roof types. Another great feature is that the mineral granules on the shingles help to deflect harmful, roof-damaging UV rays.
Disadvantages
Due to the asphalt shingles being pretty lightweight, they can sometimes be susceptible to wind damage. Strong winds have been known to lift or tear these shingles off easily.
Excess moisture and heat can shorten the lifespan of the asphalt shingles. Damaged shingles can expose your roof structure to the elements, thus further damaging it. Excess moisture can also lead to the growth of moss and vegetation on your roof, which may block water from running off your roof.
