1. What Are Roof Blisters?
Roof blisters are raised areas or bubbles that form between the layers of roofing materials. They may look like small bubbles under the surface of shingles or roofing membranes, and can contain air or moisture. While common on flat and asphalt shingle roofs, blisters can occur on any roofing type under the right (or wrong) conditions.
2. Common Causes of Roof Blistering
Blisters are often caused by trapped moisture or air between roofing layers during installation or due to degradation over time. Heat exposure can cause the trapped elements to expand, forming raised bubbles.
3. Weather’s Role in Roof Blisters
Ohio’s hot summers and freezing winters create the perfect environment for roof blisters. UV radiation can heat roofing materials, causing expansion and vaporization of trapped moisture, while winter freeze-thaw cycles exacerbate the lifting.
4. Poor Ventilation and Moisture Traps
Attic and roof ventilation play a huge role in maintaining your roof’s integrity. Poor airflow allows heat and moisture to build up beneath the roof deck, which can lead to blisters, mold, and early shingle failure.
Ventilation issues include:
- Blocked soffit vents
- Undersized ridge vents
- Lack of intake/exhaust ventilation balance
5. Low-Quality Roofing Materials
Cheaper or off-brand roofing materials may not have the same protective coatings or adhesive strength as premium shingles. Over time, these materials can deteriorate faster and are more prone to blistering.
At S&K Construction and Remodeling, we only use trusted materials, like Owens Corning Duration Shingles, designed for durability and blister resistance.
6. Improper Roof Installation
Roofing is both an art and a science. If shingles are installed with moisture present or not pressed properly, air bubbles and moisture pockets can form. Roofing done in humid or rainy weather without proper drying time also increases the blister risk.
Bad installation practices include:
- Trapped moisture between shingle layers
- Lack of underlayment
- Improper sealing
7. How to Identify Roof Blisters
Signs of roof blisters include:
- Bubbled or raised shingle surfaces
- Popped blisters with exposed substrate
- Cracks or soft spots in blistered areas
- Discoloration or loss of granules
Inspect your roof periodically or after storms to catch early signs.
8. Are Roof Blisters Dangerous?
Blisters that remain unpopped may not immediately compromise roof performance. However, popped blisters can expose the underlayment or decking, leading to leaks, rot, and reduced energy efficiency.
Left untreated, roof blisters can:
- Shorten roof lifespan
- Increase utility bills
- Result in costly interior damage
9. The Difference Between Blisters and Hail Damage
It’s easy to mistake roof blisters for hail damage. Both can result in missing granules and raised spots, but:
- Hail damage has sharper edges and more uniform patterns
- Blisters appear more rounded and random
A trained roofer can help distinguish the two, especially for insurance purposes.
10. DIY Roof Inspection Tips
Want to safely inspect your roof?
- Use binoculars from the ground
- Check the attic for light spots or moisture
- Inspect after extreme heat or storms
Avoid walking on blistered shingles—they’re fragile and can worsen the problem.
11. Temporary Fixes vs. Permanent Solutions
Temporary patches (like roofing sealant or tar) may stop immediate leaks but don’t address the root cause. Permanent repairs involve:
- Replacing damaged shingles or membranes
- Improving ventilation
- Upgrading materials
12. When Is It Time to Replace the Roof?
If blisters are widespread, or your roof is over 20 years old, it may be more cost-effective to replace the entire roof. Replacing your roof also improves curb appeal and energy efficiency.
