Asphalt shingles have a 20 to 30-year lifespan on average. However, long-term exposure to extreme heat and ultraviolet (UV) rays can cause cracking and splitting. To solve these problems effectively, it’s important to know the difference between asphalt shingle cracks and splits.
Asphalt Cracks vs. Splits
Asphalt shingle cracks occur when they lose flexibility and waterproofing ability due to diminishing volatiles. High humidity, evaporation and roof age contribute to the reduction of the volatiles, causing the roofing material to shrink and cracks to form on the surface. Low-quality shingles often suffer from premature cracks.
Meanwhile, splitting is a result of the constant expansion and contraction of the asphalt shingles over time. The heat during summer encourages expansion while the cold weather in winter causes contraction. This continuous cycle weakens the roof’s adhesive strips, causing diagonal splits on the shingles.
How to Prevent Asphalt Shingle Cracks and Splits
- Use High-Quality Shingles
Low-quality roof shingles are made with poor manufacturing standards. Often, they have thinner surface layers and a weaker base. You can consult your trusted roofing professionals about the best roof shingles to use based on your local weather pattern.
- Opt for Cool Roofs
Cool roofs prevent asphalt shingle damage by reflecting sunlight and avoiding heat and UV damage. For cool roofs, lighter colors are generally effective in reducing the temperature of the roof and the heat absorbed by the roof.
- Hire Qualified Contractors
Work with skilled and experienced roofers to ensure the proper installation of your asphalt shingles. Quality workmanship is a significant factor in your roof’s longevity. If your shingles aren’t properly installed, they become more prone to damage and have a shorter lifespan.
