When choosing a new roof for your roof replacement project, it’s important to consider the durability and longevity of your roof. If you’re looking for a roofing system that is both reliable and long-lasting, an asphalt shingle roof is an ideal choice. Most roofing contractors say that it can last for about 25 to 30 years, but you can’t help but wonder if it will actually last that long.
Expert Contracting discusses how long your asphalt roof should last and the factors that may affect its aging.
How Long Should Your Asphalt Roof Last?
The two most common types of asphalt shingles are the three-tab and dimensional shingles. While three-tab shingles typically come with a 25-year manufacturer warranty, dimensional shingles come with a 30-year manufacturer warranty. If your asphalt roof is installed correctly, and if you have a good ventilation system, you can expect to benefit from about 80% to 85% of the life span of an asphalt roof. For a three-tab shingle roof, this means 20 to 22 years; for dimensional shingles, 25 to 28 years.
What Are the Factors That Affect the Aging of Your Roof?
Over time, your asphalt shingle roof may experience weathering. It’s a term used to describe the effects of shingles when exposed to the elements. It’s a natural process that will cause shingles to slowly deteriorate. Here are some factors to consider that may affect the weathering of your roof:
- Shingle quality. Quality will vary among manufacturers, so know that low-quality shingles are likely to fail earlier than high-quality shingles.
- Structure orientation. Due to increased thermal and UV exposure, south-facing roofs have shorter life spans.
- Roof slope. Since they shed moisture more slowly and are more directly exposed to UV radiation, flatter roofs have shorter life spans compared to roofs with steeper pitches.
- Roof color. If you have a dark roof, keep in mind that it may absorb more heat, shortening the shingles’ life span and increasing the thermal cycling.
- Roof ventilation. Without a good attic ventilation system, shingles and the entire roof structure won’t be kept as cool and healthy. This leads to an accelerated loss of volatiles, among other problems.
- Roof maintenance. For a longer life span, be sure to schedule regular roof inspections and follow proper maintenance so that roofing experts can repair any issues and prevent further damage.
