Regularly scheduled roof maintenance is one of the best investments a home or business owner can make. Your roof is your first line of defense against the elements and provides a protective barrier around what matters most. A roof left unmaintained will start to deteriorate and cause problems for your structure. For asphalt-shingle roofs, blistering is a common occurrence that can plague a neglected roof. While roof blistering can be considered harmful, the good news is that it is entirely preventable when you make one call to Ridgeline Construction Roofing & Exteriors. We’re your roofing experts, with decades of knowledge and experience about shingle blistering and how to prevent it.

What is Roof Blistering?

Left unattended, asphalt-shingle roofs will begin to bow, or blister, due to the trapped air beneath or within the different layers of your structure’s roof. As the outside temperature increases, the pressure from the trapped air or moisture expands, weakening the roof and causing a blister. When caught early, small or isolated shingle blisters are a quick fix. Roofs exposed to massive rainfall will eventually allow water to seep in, and over time create detrimental leaks and other water damages. Once this happens, a total roof replacement is usually the only option. 

What Causes a Blistered Roof?

While there are many factors that can contribute to a blistered roof, there are a few main suspects when it comes to determining the cause.

1. 1. Poor Installation — Whether it’s a total roof replacement or just a simple repair, you should always hire trusted and trained professionals for the job. At Ridgeline Construction Roofing & Exteriors, our installation experts never cut corners, but instead, create a comfortable a safe space for your building.
   2. Poor Attic Ventilation — One major issue you need to address to help prevent roof blisters is attic ventilation. You’d be surprised how many homes do not have proper attic ventilation. A properly ventilated roof has vents on its ridges as well as its eaves. Although blistered shingles can be replaced, if the main cause isn’t corrected, you’ll likely have the same problem again. If your attic does not have adequate ventilation, your home could also have damaged insulation, hot interior spaces, and high energy bills during the summer. Trapped heat and moisture may also lead to ice dam formation and structural damage. If you plan to replace your roof, make sure proper attic ventilation is included.
   3. Poor Roofing Materials — The quality of the materials you decide to use for your roof is equally as important as the contractor you hire. You always want the best possible, durable materials that are going to stand the test of time. While it may be pricier on the front end, it could eventually pay for itself.

Can Roof Blistering be Fixed or Prevented?

Depending on the size of the damaged area, a blistered roof can typically be repaired. Although roof blistering can cause severe harm to your home or business’s roof, it can be largely avoided with routine maintenance. Regularly scheduled roof check-ups are the best way to catch shingle blistering early, and they will prevent otherwise imminent roof blisters.
