Shingle roofs typically last 20 to 30 years, but Tucson’s climate can shorten that lifespan considerably. Between the relentless sun and extreme summer heat, asphalt shingles and the underlayment beneath them break down faster here than almost anywhere else in the country. If your roof has not been replaced in the last two decades, it may already be on borrowed time.
Below are four clear signs it’s time to call a Tucson roofing contractor about a shingle roof replacement.
1. Your Roof Is More Than 20 Years Old
Roofs in Southern Arizona take far more sun exposure than roofs in cooler regions, and that exposure accelerates aging. While a shingle roof in the Northeast might last 25 to 30 years, the same roof in the Tucson area usually maxes out at 20 to 25 years. The extreme heat simply wears the materials out faster.
There is one exception to the 20-year guideline: if your home has multiple layers of shingles, expect a shorter lifespan. Stacked layers trap heat against the roof deck, which speeds up deterioration and can cut years off the expected life of the shingles.
2. Granules Are Coming Off the Shingles
Take a look at your roof. If the small colored granules that coat the asphalt shingles are loose or missing, that’s a strong sign you may need a replacement.
You can spot granule loss a few ways. Dark patches across the roof indicate spots where the black asphalt is now exposed. You might also notice a slight shine along the edges of the shingles, which usually means the granules have worn away and the underlying fibers are showing through. Either way, it’s worth having a roofing company near you take a closer look.
3. Shingles Are Loose or Blowing Off in the Wind
As asphalt shingles age, the tar strip along the front edge loses its grip. Once that adhesive fails, even moderate gusts can lift the shingles, and a strong storm can tear them off entirely.
For many Tucson homeowners, missing shingles after a windstorm is the first real sign that something is wrong with the roof. If enough shingles have blown off, most insurance companies will want the roof replaced rather than patched.
4. Your Three-Tab Shingle Roof Needs Repairs
If your home still has older three-tab asphalt shingles and you’re facing repairs, a full roof replacement might actually be your only option. Most major shingle manufacturers have stopped producing three-tab shingles for the Arizona market. A quick search through Owens Corning, for example, shows their Supreme three-tab line is not available in Arizona.
That makes finding matching shingles for repairs nearly impossible. Because the newer laminated (architectural) shingles cannot be blended with three-tab shingles, some insurance companies will agree to replace the entire roof, or at least the affected section. A qualified Tucson roofer can help you walk your insurance carrier through the issue and document why a full replacement is justified.
