Why Does Your Asphalt Shingle Roof Crack and Split?

June 4, 2023

Asphalt shingle cracks and splits can be a common issue in roofing systems usually because they've aged quite a lot, the weather in your area isn't too good, it was poorly installed, or they lack any kind of regular maintenance. It's quite easy to prevent cracks and splits from causing your roof an untimely demise – read more about it here.

Why Does Cracking Happen?

There are several reasons why cracks and splits occur:

Too Old

Over time, asphalt shingles become more susceptible to cracking and splitting due to aging and exposure to the elements. Ultraviolet (UV) radiation from the sun, temperature fluctuations, and moisture can all contribute to the degradation of the shingles.

Changes in Size

It's not just you who feels chilly or hot when winter or summer arrives. Changes in temperature cause the shingles to expand and contract, changing their size gradually. Over time, this repetitive movement can lead to stress on the shingle material, its adhesive, and joints, resulting in cracks, splits, or both.

It Wasn't Well-Installed

Did you skimp by paying an unlicensed roofer or just really bad material? If the shingles were not properly installed or if there were errors in the application process, your shingles would get damaged sooner. One example of why this happens is the changes in size – manufacturers have a proper guidelines on proper nailing and nail spacing to minimize the damage of these size changes.

Hail Damage

Hailstorms cause both rackets and expensive roofing problems. This dreaded weather condition can cause significant damage to asphalt shingles. When large hailstones or other objects strike the roof, they can create cracks and splits in the shingles.

How Do I Prevent Asphalt Shingle Cracks and Splits?

Fortunately, you can keep your roof healthier and functioning properly for longer with these steps.

Regular Inspections

When was the last time your roofer checked your roof for hidden damage? Perform routine inspections of your roof to identify any signs of damage or wear. Your roofer will look for cracks, splits, or curling shingles. Catching problems early can prevent them from worsening and potentially causing leaks.

Proper Installation

Don't sweat it if a run-by-night roofer previously installed your roof. When something happens, ensure that your asphalt shingles are reinstalled correctly by hiring a professional roofing contractor. Certified roofers, like SJ Winn Construction, follow the manufacturer's guidelines and best practices for installation to minimize the risk of future issues and ensure you have full warranty coverage.

High-Quality Shingles

Poor material quality leads to substandard durability and dependability. That's the reason why you should invest in high-quality asphalt shingles that are designed to withstand the climate and weather conditions in your area. Cheaper or lower-quality shingles may be more prone to damage and deterioration.

Ventilation and Insulation

When your attic gets too hot and stuffy, it's going to pop and suffer from long-term damage sooner or later. Proper attic ventilation and insulation play a crucial role in maintaining the temperature and moisture levels of your roof. Adequate ventilation helps prevent excessive heat buildup and reduces the risk of thermal expansion and contraction, preventing significant asphalt shingle and roof structure damage.
