Lifespan of Asphalt Roofs: All You Need To Know
If you have a new asphalt roof, you may wonder how long it will last and when it needs replacement. The guide below will help you predict your roof's lifespan, what elements affect longevity, and how to make an asphalt roof last long.
How Long Does an Asphalt Roof Last?
Asphalt shingles are dependable and inexpensive and dominate the residential roofing market. The material's expected lifespan is 15 to 30 years and typically comes with a 25-year warranty.
However, the lifespan of your asphalt roofs primarily depends on the type of shingles. The 3-tab asphalt shingle is the cheapest and most popular, which features cutouts at its lower edge to give the appearance of three shingles. This shingle is on the lower end of the lifespan spectrum, with a shorter lifespan compared to the architectural shingle.
Architectural shingles feature a thicker base mat than 3-tab products, making them sturdier and heavier. The shingles also have more granules on their coating and stronger adhesives. As a result, architectural shingles last longer than 3-tab asphalt roofs.
The average lifespan of architectural shingles is 25 to 30 years. Some architectural products last over 30 years, although warranties depend on the manufacturer.
Factors Affecting an Asphalt Roof's Lifespan
Your asphalt shingle may last longer than its lifespan or fail prematurely, depending on many factors, including:
Installation Quality
The installation quality sets the tone for the roof's durability since installation errors cause many roof problems like seam failure and leaks. A certified and seasoned roofer only uses high-quality materials that stand the test of time. Moreover, reputable contractors offer warranties to cover installation errors.
Weather Conditions
Weather exposure is another factor that affects an asphalt roof's lifespan. For instance, intense heat accelerates roof damage, while strong winds can loosen or blow off shingles, leaving the roof vulnerable to water damage.
If your region experiences heavy rainfall, professional installation is the only way to discourage leaks on your asphalt roof. A licensed roofer slopes your roof correctly and designs an effective drainage system to prevent water from pooling on your roof.
Ventilation
Heat and moisture weaken asphalt shingles, reducing your roof's lifespan. A poorly-ventilated attic is especially destructive because it traps hot and cold air, leading to mold, rot, and ice dam formation. You must properly ventilate an asphalt roof if you want it to last long.
Roof Maintenance
Neglected roofs are more likely to have leaks, pest activity, and mold, which affect their lifespans. You must schedule regular inspections to ensure your roofer catches leaks, cracks, and missing shingles early before they cause extensive damage. Inspections are especially critical after extreme conditions like storms and hurricanes so your roofer can repair damaged areas.
How to Extend Your Asphalt Roof's Lifespan
You can extend your asphalt roof's lifespan with a few strategies. First, don't pressure wash shingles since pressurized water loosens the granules coating the roof. These granules prevent the roof from being exposed to the elements to extend its lifespan. If your roof has mold, mildew, or dirt, have a roofing professional clean it and repair the deteriorated sections.
You should also clean your gutters regularly since pooled water can damage your roof. Over time, gutters accumulate tree branches, leaves, and debris, preventing water from flowing properly. The longer water stands in clogged gutters, the quicker it deteriorates the roof, resulting in expensive repairs.
While trees add a natural charm to any property, they can damage your roof if they are too close to your roof. Stray branches can scratch shingles and falling limbs can puncture the roof. Be sure to trim trees regularly to keep branches away from the roof.
