At RNC Roofing and Construction, we know that a well-maintained roof is crucial for the safety and security of your home. If you are a homeowner, it is vital to keep an eye out for potential issues that could damage your roof’s integrity. One of these issues is blistering shingles. In this article, we will explore what blistering shingles are, what causes them, and what steps you can take to prevent and fix them.

What are Blistering Shingles?

Blistering shingles are a common roofing problem that occurs when bubbles or blisters form on the surface of your shingles. These blisters can range in size and can appear on individual shingles or in larger patches. Although blistering shingles may not seem serious, they can damage your roof’s integrity and lead to more significant issues if left unaddressed.Asphalt shingles are the most common type of shingle used on residential roofs in North America. They are made of a base material (either organic or fiberglass) coated with asphalt and topped with a layer of ceramic granules. When the asphalt in the shingles is exposed to high temperatures, it can soften and expand, causing the shingles to blister.

What Causes Blistering Shingles?

Several factors can cause blistering shingles. One common cause is excessive heat. When shingles are exposed to high temperatures for extended periods, they can begin to blister and bubble. This is particularly true for roofs that are poorly ventilated or located in areas with intense sunlight.Moisture is another common cause of blistering . When water gets trapped between the layers of your shingles, it can cause them to bubble and blister. That’s why it is essential to ensure that your roof is correctly waterproofed, and any leaks are repaired promptly.

Why Are My Roof Shingles Blistering?

Blistering Shingles is a common issue with asphalt shingles. There are two main reasons for blistering on shingles

  • Trapped Moisture

The first cause of blistering on shingles is due to manufacturing errors that allow moisture to get trapped between the layers that comprise the shingle. Most asphalt roof shingles consist of three layers:

-The backing, composed of paper or fiberglass

-The asphalt

The granules

When the moisture stuck between these layers heats up from sun exposure or attic heat, it expands or turns to vapor, forming blisters.

  •  Poor Ventilation

Blistering on shingles may develop or worsen if your roof is poorly ventilated. A poorly ventilated roof allows heat and moisture to build up in the attic, leading to shingle deterioration and damage.

Preventing Blistering Shingles:

The best way to prevent blistering is to ensure that your roof is correctly ventilated and waterproofed. Regular inspections and maintenance by a professional roofing contractor can achieve this. Additionally, it’s important to keep your gutters clear of debris and to remove any overhanging tree limbs that could damage your roof.


Proper Roof Ventilation

Ventilation is crucial in preventing blistering shingles. Attic vents allow for the release of warm, moist air that can build up in your attic. This, in turn, prevents the shingles from overheating and blistering. Proper attic ventilation also helps reduce energy costs by allowing hot air to escape, making it easier to cool your home.

Waterproofing your roof is another critical step in preventing blistering shingles. Ensure that your roof is properly waterproofed by having a professional Roofing contractor install the right underlayment and ice and water shield. These materials help prevent moisture from getting trapped between the layers of your shingles and causing blisters. It’s essential to choose the right underlayment and ice and water shield for your roof type and climate, as different materials are designed to withstand different weather conditions.

A professional roofing contractor can identify potential issues before they become significant problems and recommend the necessary repairs or replacements.

  • Call a Professional

  • Identify the Cause

The first step is to identify the cause of the problem. If the issue is due to poor ventilation, it’s essential to improve your attic ventilation. If it’s due to trapped moisture, you’ll need to replace the affected shingles.

  • Replace Damaged Shingles

If the blistering is limited to a few shingles, it’s possible to replace them individually. However, if the problem is more widespread, it may be necessary to replace the entire roof.
