The 5 Possible Reasons For Your Roof’s Granule Loss

Overtime, you may notice that your roofing system is losing its shingle granules. Some homeowners get worked up over whether or not this is something to worry about. The short answer is that it actually depends on the root cause as to why the roof is shedding its granules in the first place. Once you learn that, you’ll know whether or not granule loss is something you should worry about.

Possible Reasons For Your Roof’s Granule Loss

In this post, window repair pros from High Performance Homes discuss the five possible reasons why your roofing system is losing its shingle granules.

  1. Blistering – Blistering is one of the common causes of granule loss in your roof and often occurs due to aging, wear and tear, or storms that allow moisture to get stuck in your shingles. If your shingles are blistering and causing the roof to lose its granules, then it’s something that you should worry about as your roofing system is in need of repairs.
  2. Defects – If your roofing system is showing bald patches or exposed shingle substrate early in its chronological rlife, it’s possible that there’s a defect on the shingle itself. To determine if this is indeed the case, hire a professional to inspect your roof immediately and replace the shingles if needed.
  3. Age – As your roof ages, you can expect it to start losing its granules since the bond between the granules and shingle becomes looser. If you know your roof has some years behind it and is already starting to shed its granules, consider replacing your roofing system as soon as you can.
  4. Hail Damage – Hailstones, especially large ones, can cause significant damage to your roofing system. One type of damage that your roofing system can sustain from hail is granule loss. If you notice your roof shedding granules after a hail storm, consider having it repaired or replaced as soon as possible as such roofing systems now have a reduced lifespan. To get experts in repairing and replacing your roof, turn to the exterior house contractors of High Performance Homes.
  5. New – If your roofing system is new and you notice that it’s shedding a few granules, you don’t have to worry too much. When your shingles are manufactured some excess granules may attach themselves to the embedded granules. These excess granules may fall off during packaging, shipping, installation or after a rainfall. However, if this continues after a set amount of time, it’s possible that the product may be defective and should be replaced as soon as possible.

“This contracting company recently replaced all the windows in my home. All of the associates I interacted with along the way were pleasant, knowledgeable, and professional. The way the windows were installed was done with precision and care for my home, and I did not have to pay any extra for trim around both the outside and inside of the windows. The end result is pleasing to look at, and I can already tell there’s a big difference in how insulated my home is.”
