Blistering vs. Hail Damage: How to Tell the Difference

There are many reasons for roof repair in Arkansas, but two particular issues stand out as more frequently occurring events: hail damage and shingle blistering.

💡 Blistering vs. Hail Damage: Why Is Diagnosis So Important?

It’s vital to be able to tell the difference between roof damage caused by blistering and that caused by hail. For starters, determining the root cause of the problem impacts the treatment plan. Blistering is typically the result of shoddy installation, low-quality manufacturing, or inadequate attic ventilation, while hail damage is caused by severe, uncontrollable weather conditions. Knowing what caused the damage will help your roofer determine the next steps. Plus, the cause of the damage can impact whether or not your insurance carrier agrees to reimburse you for any repairs — something that should definitely be on your radar! 

Signs of Hail Damage

There are a few simple ways to spot hail damage. Often, there are physical manifestations. A telltale sign is the presence of roofing granules in your gutters and downspouts. Additionally, hail makes large indents or divots in your roof. The area surrounding these spots will be flat with a lack of texture as the granules are often stripped off during a hail storm. You can also check the metal portions of your roof (like the flashing) for damage. Metal takes the brunt of hail damage, and you’ll notice dents and dings on the metal parts of your gutter system — often a sign of hail. 

Signs of Blistering

Blistering is a more prolonged process, as visible, concerning damage takes a while to develop. That said, partnering with a good roofing company will help you identify early signs and be proactive with your roofing care. Blistering results in raised dimples across your rooftop. They can look similar to hail marks to the untrained eye, but your roofer will be looking for a raised circle around the mark — an indication of residue from a rising blister. This contrasts with hail marks in which the surrounding area is relatively flat or indented. If you’re still within your warranty period and you notice any pock marks, you can assign the damage to poor manufacturing or installation. 

👉 3 Key Differences Between Blistering and Hail Damage

Understanding the key differences between blistering and hail damage is crucial for identifying and addressing these issues.

1. Appearance

Blistering appears as bubbles or raised areas on your roof’s surface, while hail damage presents as dents, cracks, or punctures. Blistering is typically caused by internal issues within the roofing materials, whereas hail damage is the result of external impact from hailstones.

2. Causes

Blistering is often due to poor installation, low-quality materials, or prolonged exposure to heat. In contrast, hail damage is caused by the impact of hailstones during a hailstorm. The underlying causes of these issues are different, requiring different approaches to prevention and repair.

3. Impact on Roof Integrity

Blistering can weaken your roof’s surface, making it more susceptible to further damage from the elements. Hail damage can compromise your roof’s ability to keep water out, leading to leaks and other issues. Both types of damage can affect your roof’s integrity, but they do so in different ways.

🤔 I’ve Spotted the Signs. Now What? 

If you’ve identified signs of hail damage or blistering on your roof, it’s important to act quickly to prevent further deterioration and ensure your home’s protection. Here’s a guide on the steps you should take:

Decide on Repairs or Replacement

Maintain Regular Checks
