What Is Degranulation
The Third Estimate
May 4, 2022
Asphalt shingles have granules on their surface to help the shingle retain its color and to prevent heat from permeating the house. Granule loss can be an important sign that your roof needs repair.
What is Roofing Degranulation?
There are several causes of roofing degranulation, including extreme weather and manufacturing defects. Another problem may be improper ventilation of the roof. If you notice spots on your roof with a shiny appearance, the fiberglass that holds shingles together has been exposed. You should consult a roofing professional to determine the cause of the shiny spots and take the necessary measures to restore the integrity of your roof. This article will explain the causes and signs of roofing granule loss.
Roofing granule loss
If you have noticed a large amount of granules in your eavestroughs, you may need to consult a roofing contractor. This can indicate balding shingles on your roof, which may signal the end of their life. Roofing granules are important components of asphalt shingles and are necessary to protect the roof from UV radiation. Granule loss can also indicate the need for a new roofing system.
Granule loss is a normal occurrence on shingles. However, if you notice to many granules missing, especially over a large area, you might consider replacing your roof. While it's normal for your shingles to lose granules over time, it can indicate a variety of problems. Roofing granule loss is most likely a result of improper installation. Installing shingles improperly (called laddering or stair-stepping) results in considerable granule loss.
Signs of premature granule loss
The first step in addressing premature granule loss is to determine where the problem lies. Consult a roofing contractor to determine if any part of the roof is susceptible to granule loss. If so, a contractor can help reinforce those areas during replacement. Otherwise, this problem can indicate a manufacturing defect.
Another common cause of granule loss is extreme weather events. Heavy winds and hail can loosen granules, and if this occurs, the granules may fall. Whether granule loss occurs due to the impact of heavy winds or by the weight of hail is difficult to determine. During an intense weather event, a professional roofing contractor should inspect the roof. The assessment should include estimating the extent of the damage and whether it can be repaired or replaced.
Causes of granule loss
Roofing granule loss is a normal part of the lifespan of an asphalt roof. Asphalt shingles are weather resistant and waterproof, but they are not immune to granule loss. In fact, granule loss is common and can signal the need for a new roof. Whether a roof is new or old, regular inspections are necessary to determine the cause and repair any flaws.
There are several causes of granule loss. These include age, airborne debris, and even walking on a roof. Although most roofs are meant to withstand a great deal of wear and tear, granule loss is usually uneven, and may occur in only one spot. This type of loss is not only annoying but also potentially dangerous. If you notice granule loss on your roof, consult a professional roofing contractor.
Signs of roof damage caused by granule loss
Asphalt shingles have granules on their surface to help the shingle retain its color and to prevent heat from permeating the house. Granule loss can be an important sign that your roof needs repair. However, granule loss is not always cause for concern. New asphalt roofs often have excess granules on their surfaces due to improper packing. These loose granules will wash away from your roof shortly after installation.
While granule loss is usually a normal process associated with weathering, excessive occurrences are a more pressing matter. This type of damage indicates that your asphalt shingles are beginning to age, are weakened, and need repair. Additionally, water leaks may also occur as a result of granule loss. Water leaks, meanwhile, are an obvious sign that your roof has been compromised. If you notice dark stains on the roof, the damage is likely caused by water.
