The roof is an important part of a home because it protects the structure from elements like heat, wind, rain, snow, and hail. Most roofs do not last forever and during the course of homeownership, many people must have their roofs replaced. It helps if they are aware of the different kinds of asphalt roofing shingles. This helps them make a more informed decision regarding which shingles to use.
Asphalt Shingles Are Not All the Same
Observe the shingles on roofs through a neighborhood and you will quickly realize that they are not all the same. Asphalt shinglees are the most common in the US and they are made from waste paper. Asphalt is used to saturate the paper, making it waterproof, and a coating of adhesive asphalt is added. Ceramic granules are embedded in this coating and if the shingle is algae-resistant, some of these granules feature ceramic coated leachable paint that prevents algae from discoloring the roof.
A fiberglass shingle is a type of asphalt shingle that features a fiberglass mat that increases durability. The mat contains wet fiberglass and a urea-formaldehyde resin. Its asphalt coating provides a waterproofing quality. A fiberglass mat is typically more fire resistant than the paper mat used to make traditional asphalt shingle.
Laminated dimensional shingles are fiberglass shingles with two layers bonded by an asphalt sealant. They are heavier, more durable, and more expensive than a traditional shingle. Their aesthetic quality is also appealing to homeowners. These shingles provide a roof with a contoured and varied visual quality and for this reason, they are often called architectural shingles.
Lifetimes of Asphalt Shingles
The warranty for an asphalt shingle typically spans from 20 to 50 years based on type and brand. Some newer styles feature a lifetime warranty. However, statistics reveal that an asphalt roof lasts between 15 and 20 years. The asphalt roofing industry lists the lifetime of an average shingleed roof as 17 to 19 years, much shorter in climates that are hot or regularly experience extreme weather.
Homeowners should be aware of the age of their roofing shingles and conduct regular inspections to identify whether repair or replacement is necessary. Keeping damaged or worn shingles on a roof may allow water to see into the home, damaging its structural integrity. An experienced roofer can help a homeowner determine when shingle replacement is needed and which type of shingle is the best choice.
