The High-Altitude UV Threat
In Utah, the sun is a major silent killer of roofs. High elevation means more intense UV radiation, which “bakes” the essential oils out of asphalt shingles. This leads to thermal shock, where shingles become brittle and crack during the rapid temperature swings common in the high desert.
Snow, Ice Dams, and Wind
- Ice Damming: When heat escapes your attic, it melts snow on the roof. That water then refreezes at the cold eaves, forcing water upward under your shingles.
- Wind Uplift: Utah’s canyon winds can catch the edges of aged shingles, peeling them back and exposing the underlayment to the elements.
Signs of Weather-Related Fatigue
- Bald Spots: Excessive granules in your gutters are a sign your shingles have lost their UV protection.
- Curling Edges: A sign of dry-out from years of heat exposure.
