Asphalt shingles are the most widely used roofing material today. That’s why they’re cheap, plentiful and simple to install. Despite their popularity, asphalt shingles have their own set of issues, including shingle breaking and splitting. But what is the distinction between the two?

StormROOF Systems, LLC, the region’s experts in disaster restoration, discuss the differences.

What is Asphalt Cracking?

Volatiles are low-boiling-point chemicals that are added to asphalt roofing shingles to make them more flexible and water-resistant. These volatiles, however, evaporate over time and cause your shingles to become brittle and crack. This is a common symptom of a deteriorating roof. This can hasten the evaporation process if you live in a hot climate. Cracking is also increased when there is too much filler in the asphalt mix or when using low-quality shingles.

What Is Asphalt Splitting?

Splitting, also known as thermal splitting, occurs as a result of constant temperature changes. This type of damage is especially common in climates where the temperature fluctuates between extremely hot and freezing cold. Shingles expand in hot weather and contract in cold weather. This puts a lot of strain on the adhesive strips that connect them, which can eventually lead to leaks and low wind resistance.

The Key Differences Between Asphalt Cracking and Splitting

1. Appearance

Split and cracked shingles according to a professional roofing contractor are distinguished by the lines on the surface of individual shingles. Splitting, however, is distinguished by deep gaps that run all the way through a shingle.

Shingle cracks, on the other hand, are usually only surface-deep.

2. Cause

The thermal expansion causes splitting and cracking in roofing and gutters, but how it happens is different. Splitting occurs when thermal expansion leads shingle layers to literally break apart due to a fastener in one of the layers.

On the other hand, cracking occurs gradually, with thermal expansion causing tiny tears at a time, resulting in shallower fissures.

3. Degree of Damage

Splitting and cracking vary in-depth, posing varying degrees of damage to the roof. Splitting opens up a direct path for water to the roof’s weaker areas.

However, cracking weakens the entire shingle surface, perhaps causing buckling or dislodgement.
