Granule Loss and What You Need to Know

Asphalt shingles are one of the most popular roofing materials found in many modern homes across the country. They’re affordable and easy to maintain, but if there’s one issue that’s unique to this material, it’s that it slowly loses its mineral granules over time. Also known as granule loss, it’s usually expected right after a new install. But depending on the damage, the granules may still shed due to several reasons which can often lead to a full replacement to prevent future issues. 

If you think you’re having granule loss, it’s important to know what’s causing it so that you’ll know if you need to take immediate action to prevent further damage. Howard Roofing & Home Improvements shares more insight:

How Are Asphalt Shingles Made?

Asphalt shingles are typically made by having asphalt granules adhered to a shingle substrate. A layer of granular material is created which acts as a barrier protecting the shingle material against sunlight, UV rays and other natural elements. But like every other roofing material, the mineral granule layer slowly ‘sheds’ over time due to natural wear and tear. This means the protection slowly loses its effectiveness as your roof ages, it will shed a little granule loss from time to time. 

How Does Granule Loss Affect Your Roof?

Normally, granule loss can happen when your shingles were recently installed. It can stop after a certain amount of time, but if it still sheds after about a year and there’s a significant amount of granule loss, you might need to have it inspected by your shingle installer. Continued granule loss can compromise your roof’s protection against the weather and other natural elements. This can also happen more often toward the end of a roof’s lifespan, so if this is the case with your roof, then it’s time to get it fully replaced by a professional roofing contractor!

What Are the Usual Causes Behind Granule Loss?

The granules coming from your roof can be caused by several factors, but not all are immediately problematic to your roof. You can expect some granule loss as part of your roof’s normal wear and tear, but they can also come from excess granules that got loose after a few rain showers. They can also come loose during the manufacturing, shipping or installation process.
