Cracking and Splitting Shingles: What’s the Difference?

Asphalt shingles are a popular roofing material known for their durability and cost-effectiveness. Over time, however, they can show signs of wear and tear, including cracking and splitting. While these terms may seem interchangeable, they actually refer to distinct types of damage with different causes and implications for your residential roofing system. In this post, local roofing expert Christian Brothers Roofing explains the difference between asphalt shingle cracking and splitting.

Asphalt Shingle Cracking

Cracking in asphalt shingles typically occurs due to age, exposure to the elements and thermal cycling. Shingles can become brittle and less flexible as they age, making them more prone to cracking. Prolonged exposure to UV rays, temperature fluctuations and moisture can accelerate this process.

These cracks often appear as linear or jagged lines across the shingle’s surface. These cracks may be small or extend across the entire shingle length, depending on the severity of the damage.

Shingles with cracks can compromise the integrity of your roof by allowing water to penetrate through the cracks. This can lead to leaks, water damage and even structural issues if left unaddressed.

Asphalt Shingle Splitting

Asphalt shingles can become brittle with age and when subjected to additional stress, such as from foot traffic or falling debris, they may split along their natural weaknesses.

Splits in asphalt shingles often manifest as a separation or gap along the edge of the shingle, resembling a tear or rupture. Unlike cracks, which may extend across the shingle’s surface, splits tend to occur at the edges.

Splits can be problematic because they create openings that allow water to infiltrate beneath the shingle. This can lead to water damage to the underlying roof structure and, ultimately, compromise the overall integrity of your roof.
