A residential asphalt roof has an estimated lifespan of between 20 and 30 years, depending on the type of shingles used for the installation. However, few structures end up attaining their projected lifespan. An asphalt roof can fail before the end of its usable life due to exposure to threats that cause premature wear and tear to the materials. Therefore, if you want your roof to last longer, pay attention to these top threats to the longevity of an asphalt roof.
Inclement Weather
Inclement weather can damage asphalt shingles and the fiberglass base mat underneath the surface. When this happens, the roof leaks and exposes the framing to moisture damage if there is no underlay. Below are the main weather elements that can damage an asphalt roof.
Hailstones
Hailstones are common in hail-prone areas, and they can cause severe damage to asphalt shingles. The stones hit the roof at high velocity, causing the shingles to crack, dent, or become misaligned. Cracks and dents act as entry points for moisture, which further degrades the shingles and causes them to become loose. If you live in a hail-prone area, inspect your roof after a hailstorm to locate damage early. Replace cracked or misaligned shingles to prevent leaks.
Strong winds
Strong winds can dislodge asphalt shingles, especially on older roofs, exposing the structure to moisture infiltration. They can also break off large branches of nearby trees, causing them to fall on the roof and damage the shingles. Conduct frequent roof inspections to locate loose shingles. If your area is prone to high winds, cut any branches overhanging your roof to protect the shingles from impact damage.
Roof Penetrations
Do you have a chimney, solar panels, or air conditioning equipment on your roof? If so, these penetrations can shorten the structure's lifespan. If you don't install and seal the equipment correctly, the seals can become compromised and cause the roof to leak. Also, if your roof isn't designed to handle the weight of the equipment, it will fail. Therefore, before installing any penetrations, make sure the shingles can withstand the additional weight. Also, seal the penetrations properly to prevent leaks.
Heavy Foot Traffic
Heavy foot traffic on asphalt roofing can damage shingles and shorten their lifespan. This is especially true where the people accessing the roof aren't careful when walking on the shingles. Therefore, avoid climbing on the roof for DIY cleaning, inspection, and repairs. Instead, leave these tasks to your roofer. The professionals have the right expertise and safety gear to access the structure without damaging the shingles.
Beware of the above issues if you want to extend the lifespan of your asphalt roofing. For professional roof inspection, maintenance, and repairs, contact a roofing contractor.
