Blistering shingles can be a sign of underlying problems with your roof. Recognizing the signs early can help prevent further damage and costly repairs. This article explains how to identify blistering shingles and what steps to take to fix them.
What Are Blistering Shingles?
Blistering shingles appear as raised, bubble-like formations on the surface of your roof. They are often caused by trapped moisture, poor installation, or manufacturing defects. These blisters can compromise the integrity of the shingles, leading to leaks and water damage if not addressed promptly.
How to Identify Blistering Shingles
Look for the following signs to identify blistering shingles:
- Raised bubbles or bumps on the shingle surface
- Cracking or splitting of shingles around the blisters
- Granules shedding more than usual during inspection
- Visible water stains or leaks inside the attic
Causes of Blistering Shingles
Understanding the causes can help prevent future issues. Common reasons include:
- Trapped moisture during installation or from leaks
- High heat and sun exposure causing expansion
- Manufacturing defects in the shingles
- Improper ventilation in the attic
How to Fix Blistering Shingles
Fixing blistered shingles often involves replacement. Follow these steps:
- Inspect your roof to assess the extent of damage
- Remove the damaged shingles carefully using a pry bar
- Replace with new, high-quality shingles matching your roof
- Ensure proper sealing and overlapping during installation
- Improve attic ventilation to reduce heat buildup
When to Call a Professional
If you’re unsure about the extent of damage or uncomfortable performing repairs yourself, it’s best to contact a professional roofing contractor. They can assess your roof, identify underlying issues, and ensure proper repair or replacement.
Regular roof inspections can help catch blistering shingles early and extend the lifespan of your roof. Don’t delay repairs to prevent costly water damage and structural issues.
