Granules in Gutters
Sand-like particles accumulating in your gutters or at downspout bases indicate your shingles are losing their protective coating. This is often a sign of aging or damage.
While not immediately critical, this should be addressed within a few weeks.
How to Identify This Problem
Look for these warning signs:
- Sand-like particles in gutters when cleaning
- Granules piling up at downspout outlets
- Bare or dark patches visible on shingles
- Inconsistent shingle coloration from ground view
- Granules washing onto driveway or walkways
- Shingles looking thin or worn
Common Causes
Normal Aging
All asphalt shingles gradually lose granules over their 15-25 year lifespan as weather exposure breaks down the adhesive.
Hail Damage
Hail impact knocks granules off in concentrated spots, leaving the shingle exposed and vulnerable.
Foot Traffic
Walking on the roof for maintenance or repairs can dislodge granules, especially on older or hot shingles.
Manufacturing Excess
New roofs may shed loose granules for the first year - this is normal and not a concern.
Poor Attic Ventilation
Excessive heat buildup bakes shingles from below, accelerating granule loss and overall deterioration.
Low-Quality Shingles
Cheaper shingles with less granule adhesion lose their coating faster than premium products.
Solutions & Repairs
Professional Inspection
Professional RequiredAn inspection determines whether granule loss is normal aging, localized damage, or widespread deterioration requiring action.
Spot Repairs
Professional RequiredIf damage is localized (such as from hail), affected shingles can be replaced individually.
Ventilation Improvement
Professional RequiredAdding ridge vents or improving soffit intake can reduce heat buildup and slow further deterioration.
Roof Replacement Planning
Professional RequiredIf the roof is aging and granule loss is widespread, begin planning for replacement before leaks develop.
When to Call a Professional
Contact WeatherShield Roofing immediately if you notice:
- You notice a sudden increase in granule accumulation
- Large bare patches are visible on shingles
- Your roof is over 15 years old with consistent granule loss
- Granule loss occurred after a hail storm
- You are seeing other signs of roof aging
- You want a professional assessment of remaining roof life
Prevention Tips
- Choose quality shingles with strong granule adhesion ratings
- Ensure proper attic ventilation to reduce heat stress
- Minimize unnecessary foot traffic on the roof
- Schedule regular inspections to monitor shingle condition
- Address ventilation and insulation issues promptly
- Consider impact-resistant shingles in hail-prone areas
Frequently Asked Questions
How much granule loss is too much?
Some granule loss is normal over time. Concern is warranted when you see visible bare spots on shingles, consistent heavy accumulation in gutters, or when the shingles appear significantly darker or shinier than when installed. A professional can assess whether the level of loss indicates the need for action.
Can I add granules back to my shingles?
No, there is no practical way to restore lost granules to existing shingles. Once granules are gone, that protection is lost. The shingle will continue to deteriorate faster in those areas. Replacement of affected shingles or the entire roof is the only lasting solution.
Does granule loss cause leaks?
Granule loss itself does not immediately cause leaks. However, exposed asphalt deteriorates much faster when unprotected from UV rays, leading to cracking, curling, and eventual water intrusion. Granule loss is an early warning sign of problems to come.
