What Causes A Blistering Roof

The most common cause of a blistering roof is trapped water or moisture beneath the roofing material.

A blistering roof is usually caused by trapped heat and moisture. The blistering process usually starts when there’s a warm, moist area on your roof. The trapped heat and moisture cause the asphalt to soften, and the pressure from the softening asphalt pushes against the roofing felt or shingles. This can cause the shingles to buckle or lift, and eventually, blisters form.

What Are The Most Common Causes Of Blistering Roofs?

The most common cause of blistering roofs is improper installation.

If you have a blistering roof, it’s important to figure out the cause so you can make the necessary repairs. Blistering roofs are most commonly caused by one of three things: improper installation, poor ventilation, or leaks.

Let’s take a closer look at each of these causes:

1. Improper installation

If your roof was not installed properly, it’s likely that the shingles are not lying flat against the roof deck. This can cause the shingles to blister and eventually fail.

2. Poor ventilation

If your attic is not properly ventilated, the heat from the sun can cause the shingles to blister. This is because the hot air is trapped under the shingles and can’t escape.

3. Leaks

Leaks in your roof can also cause the shingles to blister. This is because the water can get under the shingles and cause them to swell.

What Are The Consequences Of A Blistering Roof?

A blistering roof can cause the roof to fail and collapse.

A blistering roof is a serious problem that can lead to a number of consequences, including leaks, mold, and structural damage. Here’s a closer look at the potential consequences of a blistering roof:

Leaks: Blistering roofs are more susceptible to leaks, as the blisters can act as weak spots in the roofing material. Once a blister pops, water can seep in and cause serious damage to your home.

Mold: Moisture from leaks can also lead to the growth of mold and mildew, which can be dangerous to your health.

Structural damage: If left unaddressed, a blistering roof can eventually cause structural damage to your home. The weight of the blisters can put stress on the supporting beams and rafters, potentially leading to a collapse.

If you notice any signs of a blistering roof, it’s important to have it repaired as soon as possible to avoid these serious consequences.

How Can You Prevent A Blistering Roof?

You can prevent a blistering roof by keeping the roof clean and free of debris.
There are a few key things you can do to prevent a blistering roof. First, make sure the roof is properly ventilated. This will allow heat to escape and prevent the build-up of moisture, which can lead to blistering. Second, keep the roof clean and free of debris. This will help to keep the surface smooth, which will also prevent blistering. Finally, if you live in an area with intense sun exposure, consider installing a reflective barrier on the roof to reflect some of the heat away.

Example:

In the scorching summer heat, the last thing you want is for your roof to start blistering. Blistering can not only be a cosmetic issue, but it can also lead to more serious problems down the road. Luckily, there are a few simple things you can do to prevent your roof from blistering in the first place.

What Are The Signs That A Roof Is Blistering?

The signs that a roof is blistering are bumps or pimples on the surface of the roofing material.
It’s important to inspect your roof regularly to look for any signs of damage. Blistering is a common issue with roofs, and it can be caused by a number of different things. Here are some signs to look for that indicate your roof may be blistering:

1. Discoloration or staining on the roof surface: This is usually one of the first signs that something is wrong. If you notice any areas of your roof that look darker than the rest, it could be a sign of blistering.

2. Cracks or splits in the roof surface: Another early sign of blistering is cracks or splits in the roofing material. This can be caused by a number of things, but it’s often the result of thermal expansion and contraction.

3. Bubbling or blistering of the roof surface: This is the most obvious sign that your roof is blistering. You’ll notice raised areas on the roof that look like blisters. These are caused by trapped moisture that’s trying to escape.

4. Peeling or flaking of the roof surface: As the blisters on your roof burst, they’ll cause the roofing material to peel or flake off. This can leave your roof vulnerable to further damage.

5. leaks: One of the most serious consequences of roof blistering is leaks. If the blisters on your roof are big enough, they can create holes that allow water to enter your home. This can lead to expensive repairs and even structural damage.

If you notice any of these signs, it’s important to have your roof inspected by a professional. They’ll be able to determine the cause of the blistering and recommend the best course of action.
