If your roof seems to be aging faster than you expected, you are not imagining it. Southern Utah is one of the harder places in the country on a roof. Here is what is working against it — and what you can do about it.
Relentless UV and heat
With more than 300 sunny days a year and summer highs well over 100°F, our roofs absorb enormous UV and heat. That dries out asphalt shingles, breaks down sealants, and degrades the underlayment under tile.
Big daily temperature swings
Desert days are hot and nights cool off sharply. That constant expansion and contraction works fasteners loose, cracks brittle materials, and opens gaps at flashing over time.
Monsoon storms and wind
Late-summer monsoons add wind, heavy rain, and hail to the mix, finding any weak point the sun has already created.
How to extend your roof’s life
- Make sure your attic is properly ventilated — trapped heat ages a roof from underneath
- Get a professional inspection once a year and after major storms
- Fix small issues (lifted shingles, failing flashing) before they become leaks
- Choose materials rated for high-UV, high-heat environments when you replace
