Blistering is a bubbling process across certain shingles. It is typically caused by moisture trying to evaporate through the material. The water molecules have nowhere to go but to press against the shingle and expand specific areas. If blistering is noted, Newport News roofers must visit the home and verify if the shingles must be replaced. In some cases, a roofing professional may simply ask the homeowner to periodically inspect blistering shingles, keeping an eye out for worsening conditions.

Roofers begin with a thorough evaluation of the rooftop. They'll note any blistering on their quote sheets, including the damage's severity. Some blistering is simply aesthetic in nature. Bubbles could be completely enclosed with no cracking or breaks to the material below. In these cases, contractors can leave the shingle intact and watch it for any deterioration, or homeowners may choose to replace the blistered shingles in order to keep their roof looking good.

Blistering can also indicate a larger problem, and older roofs are especially susceptible to small leaks beneath shingles. These leaks may not damage the roof sheathing, but moisture remains trapped behind the shingle.

The roofing experts from Jayhawk Exteriors of Newport News would be happy to answer any questions you have about windows or roofing.

In this case, isolated shingles in one area may succumb to blistering that breaks through the material. Contractors may be able to replace a shingle patch, making the overall cost relatively small compared to a full rooftop replacement.

If there are a few shingles with blistering problems that are brand new, a manufacturing defect may be in play. When shingles are constructed, moisture could become trapped among the many internal layers. If this moisture isn't released, it eventually bubbles up into blistering on a rooftop. Manufacturer's warranty coverage usually pays for repairs incurred due to defective roofing materials, so homeowners should review warranty documents before a roofing project begins.

Severely blistered rooftops that aren't under warranty will usually be estimated for a complete replacement. It is often more cost effective for homeowners to replace the rooftop entirely, but a roofing professional will discuss options with homeowners after an inspection is performed.

From a ground view, it's possible to mistake algae discoloration for blistering, which is another reason to turn to a roofing professional rather. Ideally, homeowners should call roofers to the property at least two times a year. Any slight blistering or algae growth can be discovered quickly and removed in a timely manner. Allowing issues to spread across the rooftop may lead to major damage in the future.
