Signs of cracking and splitting in asphalt shingles necessitate immediate residential roof repair. They may look the same at first glance, but a thorough inspection reveals that they are actually quite different. Read on as we differentiate shingle cracks and splits. 

Cracks and Splits

Appearance

Cracks and splits are characterized by lines running along the surface of the asphalt shingles. A closer look, however, shows a stark difference between the two types of damage. Splits are deep gaps that go all the way through the roofing material while cracks are usually only superficial.

Reasons for Cracks and Splits

For residential roof installation contractors like us, the expansion and contraction of the asphalt shingles due to temperature fluctuations is the common denominator for asphalt shingle cracks and splits. Cracks are a result of gradual wear and tear, with thermal expansion creating smaller tears. Splits, meanwhile, happen due to different layers of the asphalt shingle pulling themselves apart from each other, especially when one side is securely attached to the underlayment and decking via nails or fasteners.

Extent of Damage

The depth of the gaps is what differentiates cracks and splits in asphalt shingles, which also means both issues pose varying degrees of danger to the roofing system. Cracks, for instance, weaken the shingles’ surface, causing them to buckle or dislodge from their attachments at a later time. Since splits have deep gaps, it is easy for water to penetrate through the roof’s inner layers, resulting in eventual leaks and moisture problems.

Repair and Prevention

Replacing the cracked or split shingles is the most obvious fix to the issue. Also, both problems can easily be prevented through proper maintenance. Your asphalt shingle roof will show signs of wear and tear eventually, but scheduling routine inspections with your roofer can help minimize the effects of aging and ensure its longevity and performance.
