Roof Concern: My Shingles are Fading
Roof Concern: My shingles are fading
Type of Concern: Moderate
Cause of Concern: Over time shingles can become discolored or faded. This can be due to a couple of reasons.
1- Sun bleaches out the shingles- This cause is pretty much self-explanatory. As your roof takes the beating of the sun during the summer months it eventually takes a toll on your roof. The sun can bleach out your shingles and leave them faded, brittle and dry. Brittle and dry shingles are also thin, and therefore are inefficient in protecting your home.
2- Granule loss- Granules are so important to your roof. They help protect the base of the shingle from the UV rays. When shingles lose their granules. Granule loss can be due to a variety of things. Close branches of trees that rub up on the shingles, Little critters that frequently travel across your roof from those branches can cause granule lost. The loss of granules thus leads to your shingles fading. Also, intense heat over time can cause granules to be lost from your roof due to improper ventilation.
3- Algae spots- Algae spots will contribute to the fading shingles. As algae appears on your roof it will oftentimes make it have darker or lighter areas.
Course of Action:
The first thing to do would be to determine what is causing your fading shingles. As you previously read, each of the causes of discoloration are different enough that their solutions vary greatly.
1. Sunlight- If sunlight is the cause, the shingles are brittle and thin. They are also more likely to cause a leak. The recommended action is call to a roofing contractor, for a roof inspection. The contractor will be able to determine if you need a new roof, or a repair to fix the sun damaged shingles.
2. Granule Loss- First, trim trees and make sure that other items are not touching or close to your roof. This will prevent greater granule loss. Granule loss is also a sign that your roof is getting past its lifetime warranty. Depending on how great the granule loss is, you may want to have a roofing contractor come out and inspect your home. This way you can make sure that the shingles are adequate enough to continue protecting your roof.
3. Algae Spots- While it is important to address the algae spots on your roof, this is a fairly easy solution with a couple ways to treat the algae. You can either purchase a roof algae/moss cleaner, or mix and spray your own with a bleach solution. More information about this process can be found in our Blog post: Roof Concern: Moss
