Granule erosion in asphalt shingles is a common issue, but understanding when it is a cause for concern is crucial. At Good Roofing Company LLC, we offer insights into this problem and how to address it effectively.
Causes of Granule Erosion
1. New Roof
- Excess Granules: New roofs may shed excess granules that were not embedded during manufacturing.
- Installation: Rough handling during installation can also cause initial granule loss.
- Inspection: If significant granule accumulation is noticed in gutters or downspouts, seek a professional inspection.
2. Old Roof
- Weather Exposure: Over time, weather conditions wear down shingles, causing granules to loosen.
- Regular Inspections: Conduct regular roof inspections to identify and address granule loss early.
3. Blistering
- Heat and Ventilation: Excessive heat or poor ventilation can cause bubbles (blisters) under shingles, leading to granule loss.
- Professional Evaluation: If blistering is observed, contact roofing professionals for an assessment and solution.
4. Mechanical Damage
- Impact: Heavy objects or storms can dislodge granules and cause cracks or holes.
- Damage Monitoring: Inspect the roof after storms and replace damaged shingles promptly.
5. Defective Product
- Manufacturing Issues: Poor-quality shingles may shed granules quickly.
- Contractor Consultation: Consult with a roofing contractor if defective shingles are suspected.
6. Shoddy Installation
- Improper Alignment: Poor installation can lead to shingles lifting and losing granules easily.
- Professional Corrections: If excessive granule loss occurs soon after installation, a reputable contractor should correct the issues.
