Shingle granules coat asphalt shingles to protect your roofing from harmful UV rays, keeping your home cooler while also expanding the life span of your materials. While it’s normal to lose some granules over time—eventually, resulting in the need for roof replacement—several external conditions can cause premature loss. The guide below explains some of these driving factors so you can take preventive measures.

Why Do Asphalt Shingles Lose Granules?

1. New Roofing

Don’t be alarmed if you spot some shingle granules in your gutters or on your lawn following a roof replacement. Between packing, shipping, and installation, some loss is natural. However, if you have cleared the gutters of this residue only to see it return within the coming weeks or months, your roofing may have been installed improperly. Hire a different contractor to investigate.

2. Foot Traffic

Walking along the surface of the roof can cause the asphalt to wear. Therefore, avoid going on your roof yourself—either to perform DIY repair work or to put up holiday decorations. Professionals have the tools and experience to perform these tasks unobtrusively to help you avoid roof damage.

3. Cosmetic Blistering

Blisters can form on your shingles as a result of gas bubbles forming in the material from exposure to high temperatures. If left untreated, blisters will eventually turn into weathered pits and expose the shingle mat. Higher-quality asphalt shingles are less likely to have this problem; however, you can also reduce the risk of issues by ensuring your attic has good ventilation so that hot air can escape instead of rising through the roof.

4. Severe Storms

Hazardous weather conditions also cause your shingles to shed granules. Hail and debris from strong winds, in particular, can leave pitting that exposes the bare shingle underneath. Therefore, after weather incidents, have an inspector come and replace any damaged shingles before water can leak underneath your roof. Moisture intrusion can lead to damage ranging from mold and mildew growth to wood rot.
