Roof Blisters vs Hail Damage: How to Tell the Difference and What it Means for Your Roof

Hail, ice that forms in the upper atmosphere, can be massive, reaching the size of a softball. Large hailstones are capable of causing significant damage to cars, houses, and other surfaces.

Roof Blisters vs. Hail Damage – Understanding the Differences

1. What are Roof Blisters and How Do They Form?

Roof blisters occur when moisture becomes trapped within the layers of your roof. These blisters are typically formed due to improper installation methods, poor ventilation, or inadequate roof design. When moisture seeps into the roofing materials, it gets trapped, forming water or air pockets between the layers.

As temperatures fluctuate, especially under the sun’s heat, the trapped moisture expands, causing the roofing material to bulge or blister. Over time, these blisters can increase and eventually rupture, leading to severe leaks and water damage within your home.

Taking Appropriate Measures

Roofing blisters are widespread in areas with high humidity or where there is a lack of proper ventilation. The heat and moisture in these environments create the perfect conditions for blister formation. In addition, roof installation errors, such as an improper base layer or inadequate adhesion, can also contribute to the development of blisters.

To effectively address roof blisters, it is essential to identify the underlying cause and take appropriate measures. A professional roofing contractor will be able to assess the extent of the blistering and determine the best course of action. This may involve repairing the affected area by removing the blistered materials, addressing the moisture issue, and resealing or replacing the damaged roofing components.

2. Distinguishing Hail Damage from Roof Blisters

While both roof blisters and hail damage can cause visible marks on your roof, there are distinct differences that can help you accurately identify the issue.

What does hail damage look like?

  • Small dents on the surface of your roof
  • Circular or irregular shaped divots accompanied by cracked or missing shingles

The severity of hail damage can vary depending on the size and velocity of the hailstones. More giant hailstones, or ones that fall with greater force, can cause more significant damage to the roofing materials.

What do roof blisters look like?

  • Raised bubbles on the surface of your roof
  • Typically larger than hail dents and may have a soft or spongy feel when touched

Unlike hail damage, roof blisters are caused by trapped moisture within the roofing system. With roof blisters, you may also notice signs of water damage or leaks in the attic or interior of your home surrounding the blistered areas.

3. How Roof Blisters vs Hail Damage Can Hurt Your Roof’s Health

Understanding whether your roof has roof blisters or hail damage is crucial because it affects the overall health of your roof and the necessary repairs or maintenance required.

How Roof Blisters Can Harm Your Roof

If you have roof blisters, it indicates an underlying issue with moisture penetration. Over time, this can further deteriorate your roof’s structural integrity and compromise its ability to protect your home from the elements. The longer the blisters are left untreated, the more likely they are to burst, causing water leaks and potential interior damage.

To address roof blisters, a professional roofing expert will need to evaluate the extent of the damage and determine the best course of action. This may involve repairing or replacing the affected roofing materials, improving ventilation, and ensuring proper installation techniques to prevent future blister formation.

How Hail Damage Can Harm Your Roof

On the other hand, hail damage can compromise the protective layer of your roof, causing leaks and exposing the underlying structure to potential water damage. Hail-damaged shingles may become weakened and reduce their effectiveness in protecting your home.

Promptly addressing hail damage is crucial to prevent further issues, such as mold growth and further degradation of the roof’s integrity. Repairs for hail damage may involve replacing damaged shingles or, in severe cases, a complete roof replacement.

4. Signs of Hail Damage and Roof Blisters to Look for

In addition to understanding the differences between roof blisters and hail damage, one must be aware of the signs that indicate their presence. By being proactive and monitoring the condition of your roof, you can address these issues early on and minimize the potential for further damage.

Signs of hail damage to look for:

  • Noticeable dents or divots on your roof’s surface
  • Cracked, broken, or missing shingles
  • Granules from shingles collecting in gutters or downspouts
  • Soft spots or depressions on the top of the shingles
  • Water leaks in the attic or interior of your home

If you observe any of these signs after a hailstorm, contact a professional roofing contractor for a thorough inspection.

Understanding the differences between roof blisters vs hail damage is crucial for homeowners to address roofing issues promptly and effectively. By familiarizing yourself with the unique characteristics of each problem and their implications on your roof’s health, you can make informed decisions and take the necessary actions.
