“How long does a roof on homes in North Scottsdale last?” asked my client from Minnesota. GREAT question! We have so many different roof types in this area and they all have different longevity, depending on materials used and quality of application. The most common roof types are:
- Concrete tile roofs
- Clay tile roofs
- Mud-set tile roofs
- Built-up flat roofs
- Foam flat roofs
I asked my favorite roofing expert Mario Gallegos, owner of Patriotic Roofing, for some specific information about these roof types. Mario has been in the business of building and fixing Arizona homeowners’ roofs for 43 years. Originally an architecture student, he decided he needed some more ready income to support a growing family and has been climbing roof tops ever since!
- Concrete tile roofs – with a quality underlayment of two layers of 40# felt will last 50-60 years. If a 30# felt is used expect 15-20 years. These tiles can be reused again when the underlayment needs replacing. You may want to watch for painted concrete tiles – the color can fade over time. In 2001 Arizona passed a new code restriction of at least a double layer of 30# felt. It’s this felt or membrane underlayment that prevents the water from getting in; the tiles direct the water off the roof.
- Clay tile roofs – red, natural clay with its high curvature allows better air-flow under the tile. The tiles can be reused when the underlayment needs to be replaced. The roof life depends on the quality of underlayment used.
- Mud-set tile roofs – more expensive for the labor and extra materials, but attractive and aesthetically pleasing on the Tuscan and Mediterranean-style homes. With its layer of concrete mud between the tiles and more brittle, sand-cast tile it’s very difficult to walk on these roofs for any needed maintenance.
- Built-up flat roofs – this roof type is built up using hot asphalt and 2 or 3 layers of felt, and either flood-coated with a mop of asphalt and gravel thrown in or a cap sheet impregnated with granules to deter the ultraviolet rays from breaking down the asphalt. Depending on the quality of the application, these roofs should last 15-25 years.
- Foam flat roofs – with no seams to go wrong, this foam roof is a seamless closed cell unit, also good at insulating the roof. Regular maintenance is necessary on these roofs on homes in North Scottsdale; the Elastomeric coating breaks down and these roofs need to be re-coated every 5 years with Elastomeric – or, if you do a double-coating with granules that reflect light the re-coat can last 10 years and costs only .50 more per square foot. When homeowners ignore the necessary maintenance on this type of roof problems abound. (For reference, a foam roof runs approximately $2.50 a square foot to apply without tear-off and only .80 to 1.00 a square foot to recoat with Elastomeric coating.)
I asked Mario what homeowners could do to make their roofs on homes in North Scottsdale last their longest and he said “if your home is over 10 years of age, have a roof inspection by a licensed and bonded roofer every couple of years.”
And the roof type of choice for roofer Mario Gallegos? “I built my own home in the mountains with a metal roof – it’s lightweight and lasts forever!”
