Asphalt shingles remain the most preferred residential roofing material in the US. It is because this option is cost-effective, attractive and durable. The shingles are embedded with granules during manufacturing for added protection against the sun and the elements.
Here’s when granule loss is a sign you need to get a new roof for your home.
When Shingle Granule Loss Is a Sign of Roof Aging
Granule loss is normal in aging roofing systems. Over the life of your roof, it gets exposed to different weather conditions and elements, reducing the material’s flexibility. When your roof is approaching the end of its life, you may notice significant granule loss or bald spots on the system.
The affected areas will show the black shingle substrate. Shingles that experienced granule loss have more porosity, meaning they may be already leaking even if water damage is not yet obvious inside your home. If your roof has bald spots, it is a sign it needs replacement.
Other Causes of Granule Loss
Another reason granule loss can occur is due to foot traffic. When someone walks on your roof, some of the granules may become detached from the shingles. Excessive foot traffic can also cause bald spots on your roof. Make sure to hire an experienced professional to perform work on your rooftop. A reliable contractor will take the necessary steps to protect your roof from damage.
Blisters can either be a manufacturing defect or a sign of natural wear. It’s one of the first indications of wear on the upper surface of your roof. When someone walks on these blisters, it can leave visible damage, such as granule loss.
