6 Telltale Signs of Asphalt Shingle Aging

Asphalt shingles are among the most popular roofing materials for homes due to their durability, cost-effectiveness, and visual appeal. However, even the toughest shingles won’t last forever. Over time, exposure to the elements causes wear and deterioration that can compromise your roof’s performance. Recognizing the early signs of asphalt shingle aging can help you avoid leaks, structural issues, and costly repairs. Here are six telltale signs to watch out for.

1. Curling and Buckling

One of the first visible indicators of aging shingles is curling or buckling. As shingles lose flexibility with time, their edges begin to curl upward or the entire shingle starts to buckle. This not only affects the appearance of your roof but also increases the risk of shingle loss during strong winds and allows water to seep beneath the roofing layers, leading to potential leaks.

2. Loss of Granules

Granules protect shingles from harmful UV rays and provide additional durability. Over the years, these granules loosen and often collect in gutters or at the base of downspouts after rain. A noticeable loss of granules exposes the asphalt layer underneath, making shingles more vulnerable to cracking, weathering, and faster deterioration.

3. Cracking

Prolonged exposure to heat, sunlight, and fluctuating temperatures can cause asphalt shingles to dry out and crack. Cracked shingles are weak points in your roof where water can penetrate, leading to moisture damage inside your home. Addressing cracks early helps prevent further damage and extends the life of your roof.

4. Blistering

Blistering occurs when trapped moisture or gas within shingles expands due to heat, forming small bubbles on the surface. While minor blistering might not pose an immediate problem, popped blisters leave pits that expose the underlying layers. This speeds up the roof’s aging process and reduces its protective ability.

5. Algae Growth

In warm, humid areas, algae growth is a common sight on older asphalt roofs. While it may seem like a cosmetic issue, algae can retain moisture and contribute to the gradual decay of roofing materials, especially when granule loss is already present. If your roof shows dark streaks or discoloration, professional cleaning and treatment may be necessary.

6. Roof Sagging

Although sagging may stem from structural problems beneath the shingles, it often correlates with long-term roofing deterioration. A sagging roof may signal water damage, weakened decking, or compromised support beams. This is a serious warning sign that requires immediate professional assessment to prevent more extensive and expensive damage.
