What Causes Asphalt Shingle Deterioration?

What Causes Asphalt Shingle Roof Deterioration?Asphalt shingles are attractive and economical, and they can provide years of service. However, asphalt shingles sometimes deteriorate long before they reach the end of their expected life. There can be many causes of premature deterioration. Still, there are several commonly encountered roofing companies in Texas, including severe weather, exposure to the sun, the roof’s proximity to trees, and poor attic ventilation.

How Does Severe Weather Contribute to the Deterioration of Asphalt Shingles?

The weather in Central Texas can be unpredictable and harsh. Strong winds, hailstorms, and heavy rains can damage asphalt shingles in a single incident or incrementally over time. Wind can lift the edges of shingles, leading to cracks or breaks. Even if the shingles survive the uplift, the next strong wind can remove them and the surrounding shingles that are adhered to them. Hail can break shingles, but it can also remove the granules from the surface and leave the mat unprotected from the elements. Without protection, the mat can be damaged or lose its ability to remain waterproof. Heavy rains can gradually wash away granules, but rain can cause more severe problems if the water finds a way between or underneath the shingles. Fortunately, weather damage can sometimes be covered as an insurance restoration if the damage results from a severe storm.

How Does the Sun Cause Asphalt Shingles to Deteriorate Prematurely?

The heat from the sun causes objects to expand, including shingles and the nails that secure them. Over time, even small movements can add up to problems for your shingles. However, the sun also emits ultraviolet radiation, and UV rays are even more harmful to asphalt shingles. These rays can turn shingles dry and brittle, making them more easily damaged by the weather. If the granules are thin or missing, the asphalt coating that keeps the shingles waterproof can easily be cracked, allowing rain to enter and inflict more damage to the roof structure.

How Can Trees Inflict Damage to Asphalt Shingles?

Trees can pose problems for asphalt shingles in three ways. A heavy branch falling on your roof can cause extensive damage, but even a small one can be harmful. The second way that trees can contribute to roof damage is if their leaves clog the gutters and downspouts. The water can be forced under the edges of the shingles and start the rotting process. The third way is for low-hanging tree branches to scrape the granules from the shingles, exposing the asphalt mat.

How Does Poor Attic Ventilation Contribute to the Premature Deterioration of Asphalt Shingles?

Many people do not associate attic ventilation with a healthy roof, but roofing contractors know that poor ventilation can cause asphalt shingles to deteriorate prematurely. Heat builds up in the attic while the roof is heating up, so your shingles wind up getting baked from both the top and bottom. Some manufacturers will declare their warranties null and void if their shingles are installed over an attic with insufficient ventilation.
