The blistering that can occur on standard asphalt shingles and laminated asphalt shingles is not unusual, particularly when new shingles have recently been installed. A blistering roof can be a scary sight for any homeowner, but shingle blisters aren't necessarily a bad thing. The occurrence has to be considered in context, and any damage than can occur will be due to the blister popping or otherwise being disturbed.

When professional Union County roofers install a new asphalt roof, they usually prepare their customers for the blistering that may occur. It's important to note that newly manufactured shingles are not fully bonded. That final bonding phase takes place after the shingle is installed, and it's usually sunlight or ambient temperature that initiates the reaction. During the process, the asphalt heats up, becomes sticky and then resets. In some cases, the asphalt will get so hot that it bubbles, but those kinds of bubbles aren't actually a problem unless they break.

It's also important to note not all blistering that can occur after new shingles are installed is benign. A rare but serious defect that occurs is called shingle splicing.

Splicing is rare because quality control at the factories is quite good, and even if a splice makes it through QC, the roofer will usually catch it. If the roofer doesn't catch it, then the spliced shingle will blister, at best, or twist and deform, at worst. Keep an eye on any blistering that does occur, and homeowners should call their contractors if there's any concern.

When blisters occur either as shingle rash or in isolated locations after the setting in period, then it's an indication of shingles that have been compromised or an attic ventilation issue. If a shingle is damaged by hail, for instance, then exposure of its middle layers could make it susceptible to blistering when the weather gets warmer. Nevertheless, the vast majority of blistering issues that occur are due to inadequate attic ventilation, which causes the asphalt shingles to overheat.

Once blistering has stopped, the homeowner must determine how to proceed. If the granules remained intact when the asphalt reset, then the shingle should be fine. If the shingle has lost its granules, which may mean it looks smooth, or the blistering has left a pockmark, then the shingle should be replaced. Although patching the shingle with tar patch is an option, this option should only be used as a temporary fix.
