Asphalt Roof Granule Loss: When to Take Action
Granules play a pivotal role in the longevity and performance of asphalt shingles. Their primary function is to shield the shingles from the harmful effects of ultraviolet (UV) rays. However, over time, it's natural for some granules to shed. The real question is, when does this shedding become a genuine concern for homeowners?
The Role of Granules in Asphalt Shingles
Granules are more than just decorative elements on your shingles. They are meticulously embedded in asphalt shingles to offer a protective barrier against UV rays. Manufacturers, understanding the inevitability of granule loss over time, often embed up to 40% more granules than required in their shingles. This ensures that the shingles remain protected for a more extended period.
Identifying Concerning Granule Loss
While minor granule loss is anticipated, there are instances when the shedding can be alarming. Homeowners should be on the lookout for:
Bald Patches: If large sections of your roof start showing bald patches where granules once were, it's a clear sign of extensive granule loss.
Granules in Gutters: Another telltale sign is when you begin to notice a significant accumulation of granules in your gutters.
Excessive granule loss exposes the shingles to UV rays, leading to premature aging and potentially reducing the roof's lifespan. In such cases, considering a roofing replacement might be the best course of action.
Common Causes of Granule Loss
Several factors can contribute to granule loss:
Aging: As the roof ages, the bond between the granules and the shingles weakens, leading to increased shedding. On average, a residential asphalt roof can last about 20 years. However, this lifespan can vary based on the type of shingle used. For instance, while 3-tab asphalt shingles might last between 15 to 18 years, architectural asphalt shingles can endure for 24 to 30 years.
Installation Errors: If you notice excessive granule loss on a newly installed roof, it might be due to installation errors. It underscores the importance of hiring experienced roofing companies in Louisville KY, like Unisource Roofing, to ensure the job is done right.
Importance of Regular Roof Maintenance
To maximize the lifespan of your asphalt roof, regular maintenance is crucial. Engaging a professional roofer in Louisville KY for routine inspections can help identify potential issues early on. This proactive approach can save homeowners from costly repairs or replacements in the long run.
