The Difference Between Shingle Cracking and Splitting

Your asphalt shingle roofing sustains damage over time due to its constant exposure to the elements. High winds, for example, can lift up the shingles or blow them off, while hailstones can damage them upon impact, leaving dents or knocking off their mineral granules. In some cases, the damage is represented by cracking and splitting–which may look similar but actually has a few differences. The roof replacement experts from ARCH Exteriors, LLC share what you need to know.

Shingle Cracking

Asphalt shingles come with volatiles–chemicals with a low boiling point–which are added to the asphalt mix to make the material more flexible and waterproof. But because of evaporation, moisture, or just plain old age, the shingles gradually lose their volatiles. This causes drying and shrinking in the material. Eventually, the shingles will crack, making them more susceptible to water infiltration.

Another reason shingles crack is because of excess filler in the asphalt mix. You’ll know because the material will start randomly cracking even if they’re still relatively new. That’s why–if you’re investing in a roof replacement this season–you should choose only high-quality asphalt shingles from a trusted roofing company like ARCH Exteriors, LLC. We are an Owens Corning® Platinum Preferred Contractor, so you know the options we offer are always top-tier.

Shingle Splitting

This can occur when the asphalt shingles continuously expand and contract due to fluctuating temperatures. Called ‘thermal splitting’, it puts unnecessary stress on the adhesive strips of the material, not only causing them to lose their effectiveness, but making them more vulnerable to leaks and wind damage. When overlooked, split shingles can compromise your roof’s weather performance–enough so that roof replacement becomes more than a possibility.
