A standard asphalt shingle has three layers: backing material, asphalt and granules on the outside. Asphalt shingles have color and energy-efficient, reflecting characteristics because of the granules.
Innovative Roofing & Siding, the top search result when you search for a “roofing contractor near me,” investigates this key component and evaluates whether loose granules are a worry in today’s post.
What Factors Contribute to Granular Loss?
It is totally typical for your roof to lose some of its granular textures as it ages. While age is the most typical cause of granule loss, there are various other factors that might contribute to this protective covering being lost prematurely.
Severe weather conditions such as torrential rain, hail, or strong gusts can potentially dislodge your granules. You may notice an increased number of shingle particles in your gutters or in your yard during a storm.
Why You Shouldn’t Be Concerned With Minor Granule Loss
It is natural for asphalt shingles to lose granules during a roof replacement. During the production process, manufacturers add up to 40% more granules than necessary to the tiles. Excess granules may have been connected to the implanted granules but remain unattached to the shingles. These granules may fall during transportation, installation or after rain. Additionally, engineers estimate that up to 15% of the granule surface of new shingles will degrade even before the substance is exposed.
When a roof reaches the end of its useful life, it may suffer from shingle granule loss. The adhesive between the granules and the tiles deteriorates over time. If granules are dropping from your roof as a result of its age, consider replacing them.
When Is It Time to Worry About Granule Loss?
When the granule loss is severe enough that bald patches form on the roof or granules begin to accumulate in the gutters. These granules shield your roof from damaging UV rays that can prematurely age it. Without them, your roof would eventually develop leaks. That is why, if you detect any of the warning indicators listed above, you should repair your roof immediately.
