ROOFING AND RESTORATION BLOG

Property owners will always ask themselves, how long does a roof last on a house in the Southwest? The answer is dependent on what your local environment is. Construction materials are a challenge to endure Arizona's weather. Your roof is constantly under environmental pressure with summer heat setting records, and seasonal monsoons bringing heavy and strong winds.
Knowing the operational life of various materials in different climates can enable a property owner to make accurate budgeting decisions and be aware of when a system needs professional replacement.
Concrete and Clay Tiles: Designed for Durability
The communities of Arizona, ranging from Phoenix to Gilbert to Tucson, have many examples of tile roofs. Tiles are the top tier for long-lasting durability.
The Real Lifespan of Tile Systems
Clay or concrete tile systems can typically last for 50-100 years in the desert. The tiles are extremely durable, fire-resistant, and non-UV degrading. However, there is a catch that winemakers of the building trade wish you knew: the tile underlayment wears out much faster than the hard tiles.
The Critical Underlayment Factor
The waterproof underlayment membrane under the tiles will last for about 20-30 years. If this synthetic or felt layer breaks down, water may penetrate the structure's framing during monsoon rains. A tile roof needs a process known as a "tile roll-over" to maximize the lifespan of the roof; this involves removing the current tiles, replacing the old underlayment, and reinstalling the original tiles.

Standing Seam Metal Roofing: The Modern Durability Champion
Metal has gone from being a commercial design to being one of the best options for contemporary homes.
How Long Does a Metal Roof Last?
The typical lifespan of a metal roof in desert environments is 40 to 70 years. High-quality materials such as steel and aluminum will not dry out, split or rot during extreme heat exposure to the sun. They're extremely light in weight, which minimizes pressure on the frames of your house, and hold up well against strong winds.
Superior Thermal Performance
Metals have excellent reflectivity to the sun in addition to their durability. A metal system reflects radiant heat away from your attic space, rather than absorbing it, and can save you hundreds of dollars in cooling costs each month, and last for decades longer than traditional materials.
Asphalt Shingles: The Weakest of Materials
Asphalt shingles continue to be a popular roofing option because they are the cheapest to install, but they are the least durable in extreme Southwestern weather.
The Impact of Intense Desert Heat
An asphalt roof has a lifespan of 15-20 years in Arizona and up to 30 years on the West Coast in cooler climates. The natural oils in the asphalt matrix are cooked by the relentless UV rays, making the shingles brittle, lose their protective mineral granules, buckle or curl at the edges. When shingles become inflexible, they can be torn apart with a flick of the wind, leaving your roof deck open to leaks.
Spray Polyurethane Foam (SPF): Seamless Flat Roof Protection
Flat and low-slope roofs require special protection because the standing water is not adequately drained by regular tiles and shingles.
An Indefinite Lifespan with Proper Care
The typical lifespan of an SPF foam roof is 30 to 40 years, but it can last practically forever. The foam is applied in liquid form and expands to form a contiguous and very insulating layer. Foam is coated with a thick elastomeric white layer to prevent degradation by UV. An SPF roof will last for decades as long as its surface is cleaned and the protective UV coating reapplied in 5 to 10 years.

FAQs:
What is the life expectancy of an asphalt shingle roof in Arizona?
Asphalt shingles usually have a service life of 15 to 20 years, which is very short in Arizona because of the high levels of UV radiation and blistering summer heat.
What is the longest-lasting roofing material for Arizona's climate?
The Clay and Concrete tile systems have the longest life spans and will last for as long as 50 to 100 years. The waterproof underlayment, however, should be replaced by professionals every 20-30 years to keep a home dry.
When should I replace my roof on my home in Arizona?
These are clear indicators: cracked, broken, or missing tiles; buckling, curling, or bald asphalt shingles; recurring water leaks in the attic or ceilings; and mineral granules getting mildewy in gutters.
