Memphis sits in a humid subtropical zone with summer heat indexes above 100 degrees and relative humidity over 70 percent. This combination accelerates asphalt shingle aging and creates ideal conditions for roof blisters. When morning dew settles on your roof and temperatures climb 30 degrees by noon, moisture trapped in the shingle turns to vapor. The expanding vapor pushes against the granule layer, forming bubbles. Poor attic ventilation traps additional heat against the underside of the roof deck, cooking the shingles from below. This dual heat source causes blistering faster than in drier climates. Memphis roofs also face freeze-thaw cycles in winter, which crack already weakened blisters and let water infiltrate the decking.
