How Long Does a Roof Last in Arizona?
Your roof is a critical investment, and Arizona's intense sun and climate present a unique challenge. Knowing the lifespan of your roofing material is the first step in planning for its care and eventual replacement.
Most tile roofs in Arizona last 25–35 years. Asphalt shingle roofs last 15–20 years depending on maintenance and sun exposure. Flat foam roofs typically last 5–7 years before recoating is needed.
This guide will break down these lifespans and the signs that indicate your roof may need professional attention.
Understanding the Lifespan of Common Arizona Roofs
Tile Roofs: 25-35 Years
A tile roof is a durable choice for Arizona homes. The tiles themselves are long-lasting, but the waterproofing system beneath them has a definitive service life. The underlayment and sealants that keep water out typically last 25 to 35 years before they need to be replaced in a process called reroofing.
Shingle Roofs: 15-20 Years
Asphalt shingle roofs are a popular option, but they face a constant battle against the sun. Their lifespan of 15 to 20 years depends heavily on the quality of installation, the materials used—such as a complete GAF roof system—and consistent maintenance. Proper care can help them reach the upper end of their expected life.
Flat Foam Roofs: 5-7 Years Before Recoating
Spray foam roofing provides excellent insulation but requires a protective coating to seal it from the elements. This coating faces constant UV exposure and will degrade. Recoating every 5 to 7 years is essential to maintain the roof’s integrity and prevent leaks. A full silicone roof coating can restore protection and extend the roof's life significantly.

Roof Lifespan FAQ
Q: Does homeowners insurance cover a roof replacement?
A: Insurance typically covers damage from specific events like a major storm, but not general wear and tear over time.
Q: What is the benefit of a reroof versus a full replacement?
A: Reroofing reuses your existing tiles by replacing the worn underlayment. It is a cheaper and easier way to restore your roof's function and aesthetic without the cost of all-new materials.
Q: How long does a roof coating last?
A: A roof coating application can protect your flat foam roof for 5-7 years before another recoating is needed to maintain a watertight seal against the Arizona sun.
