What Factors Affect The Aging of Your Asphalt Shingle Roof?

Jun 15, 2020Repairing

Your asphalt shingles are one of the most important components of your home as it protects you and your family from nature’s elements. During the rainy season, their water shedding layer prevents water from seeping into your home and damaging your interior. Asphalt shingles are also one of the most common and preferred roofing materials by homeowners for roof replacement projects due to its inherent versatility, reliability, and energy efficiency.

However, asphalt shingle roofs can be affected by various elements. All of these can affect the way your asphalt roof looks over time. No matter how resilient or durable your roofing system is, weathering will eventually catch up to them. Weathering refers to the long-term effects of the elements to your asphalt shingle roof. In this blog, Home Remedy USA, the leading roofing company in your area, shares the factors that affect the aging of your asphalt shingle roof.

  1. Shingle Quality
  2. If your shingles’ quality isn’t up to par to the industry standard, it will most certainly fail faster than high-quality shingles. The quality of an asphalt shingle roof can vary from manufacturer to manufacturer, and even within their own product lines. Aside from getting a top-grade asphalt shingle roof, make sure that you hire a reputable roofing contractor to install them so that you can get the most out of your investment.

  3. Roof Color
  4. A subtle, yet critical factor that dictates the weathering of your roof is its color. A darker-colored roof tends to absorb more heat. In turn, this shortens your asphalt shingles’ lifespan by accelerating its wear and tear, moisture buildup, and thermal cycling. To address this problem, we recommend using lighter colors or shades to absorb less heat, and increase your asphalt shingles’ service life.

  5. Thermal Cycling
  6. According to roof replacement experts, thermal cycling is one of the primary causes of asphalt shingle weathering. This is especially true for areas where climate changes are frequent and extreme weather conditions deteriorate the shingles’ condition even further. This happens due to the hot and cold weather causing the shingles to expand and contract frequently, thus, wearing them down quicker.

  7. Elevation
  8. Homeowners who are situated at higher elevations may notice that their asphalt shingles will weather quickly. This is because at a higher elevation, your home is exposed to more UV radiation, which in turn, will expose your shingles to more sunlight that will deteriorate roof-covering materials and the shingles.

  9. Roofing Ventilation
  10. If your attic has poor ventilation, excessive heat and moisture won’t be able to escape from the inside. This, in turn causes the roof sheathing to warp, and your asphalt shingles to weather down quickly. During the cold months, humidity buildup from the attic can encourage mold growth which can spread to your roofing system and other parts of your home. To prevent this from occurring, your certified roofer recommends insulating your attic floor so that heat can be distributed evenly.

  11. Climate
  12. Your home’s climate is a significant factor to your asphalt shingle’s aging. If you live in a tropical area where storms and rains are a regular occurrence, this puts your shingles at risk of pooling water or water infiltration. In a hot and humid climate, your roof coverings and shingles could age quickly due to sustained exposure to extreme sunlight.

  13. Home Orientation
  14. An expert roofer would agree that south-facing roof slopes have shorter lifespans because of higher thermal cycling and UV exposure. Other parts of the roof are more affected by strong gusts of wind, compared to the others. In turn, your asphalt shingles could appear worn down on one side, but fine on the other.

  15. Degree of Roof Slope
  16. A flat roof would have a shorter lifespan since they shed away pooling water and moisture slower and have more surface area exposed to searing UV radiation compared to roofs with a steeper pitch. As such, if you’re having your roof’s internal and structural materials replaced, consider transitioning over a sloped roof to let your shingles age beautifully.

  17. Maintenance Quality and Frequency
  18. If a homeowner fails to contact their roofing contractor whenever their roof is damaged or in need of maintenance, this could lead to shingle damage and deterioration brought about by moisture intrusion and strong gusts of wind.

Asphalt Shingle Lifespan

The lifespan of an asphalt shingle roof is correlated to the rate at which they deteriorate. Their long term deterioration can be broken into three parts, namely; incipient deterioration, accelerating deterioration, and decelerating deterioration.

During the incipient phase, deterioration starts as soon as they are packaged and sent off to the homeowners. Deterioration starts very slowly and mostly progresses due to oxidation taking place within the asphalt shingles, coupled with the heat, pressure, storage, and transportation conditions. Aging accelerates quickly once your shingles are installed and exposed to the elements. It will rapidly age since it doesn’t have a chance to cure.

Once your shingles age, deterioration starts to worsen and it enters the accelerating deterioration phase. During this period, surface cracking can expose your shingles to UV radiation. For cold climates, damage could be increased since moisture expansion can turn them into ice. After the accelerating period has ended, your roof will reach the point of functional failure at which it no longer protects your roof and is starting to crumble. Every component becomes brittle and cracked, resulting in an increase in your shingles’ granule loss. At this point, your asphalt shingles are in the decelerating phase where it’s approaching the end of its service life.
