Roofing in Maricopa County, AZ
Maricopa County stretches from Buckeye to Fountain Hills and from the Gila River north past Anthem, and almost every roof in it faces the same sun, dust and summer storms. Our crews repair, recoat and replace roofs throughout the Valley.
Short answer
Across Maricopa County, the roof work homes need most is tile underlayment replacement on aging concrete and clay tile, foam and flat roof recoating, and storm repair during the monsoon. Older cores carry shingles and flat roofs, while newer suburbs carry HOA-governed tile. We work out of offices in Phoenix and Scottsdale, inspect with photos, and handle city permits for full re-roofs. Call any hour.
Maricopa County is one big metro, but its roofs come from very different eras. The older cores of Phoenix, Mesa, Tempe and Glendale hold postwar homes with shingles, flat roofs and decades of add-ons. The suburbs that filled in from the 1980s through the 2000s, from Chandler and Gilbert in the southeast to Peoria and Surprise in the northwest, are a sea of concrete tile, much of it now reaching the age when the felt underneath gives out.
Then there are the special cases. Sun City and Sun City West have their own retirement-community roofs, many low-slope or shingle, built in large phases. Scottsdale, Paradise Valley and Fountain Hills carry more clay tile, foam and complex custom roofs. The far West Valley around Buckeye and Goodyear is still adding brand-new subdivisions. Knowing the city and the era of a home tells us more about its roof than almost anything else before we climb a ladder.

A large share of Maricopa County homes went up between the late 1980s and the late 2000s, almost all with concrete tile. In cities like Chandler, Gilbert, Peoria and much of north Phoenix, those roofs are now crossing the 20 to 25 year mark where underlayment commonly fails in Valley heat. The tile looks fine, but the felt underneath cracks and lets water in during monsoon storms. We lift the tile, replace the underlayment and relay the original tile wherever it is sound.
Many of these suburbs also sit in HOAs with color and profile rules, so planning a re-roof often starts with paperwork rather than ladders. We help prepare submittals with tile samples and product sheets and schedule work around HOA limits on hours and staging. For homeowners, an underlayment replacement usually costs well under a full tile replacement while giving the roof a fresh waterproof layer for decades. Broken pieces get swapped for matching profiles, and new flashing goes in at walls, valleys and vents while the tile is off.
Downtown Phoenix, central Mesa, Tempe near the university and older Glendale hold the county's mid-century housing, plus apartments and commercial strips with large flat roofs. Here the work is mostly flat roof repair, foam recoating, parapet and scupper fixes, and shingle replacement. Many of these roofs carry multiple old layers, and tearing them off to a clean deck is often the only lasting fix. Underneath, we often find soft sheathing near old cooler curbs and at the low edges where water sat for years.
Commercial buildings across the county, from strip centers and offices to warehouses along the I-10 and Loop 303, need a different rhythm: regular inspections, coating programs, and repairs scheduled around business hours. We work on built-up, foam, TPO and modified bitumen systems. For property managers and associations with several buildings, our multifamily and HOA roofing work lays out a repair schedule by priority so budgets stretch across more than one year.

We run the work from two offices: East Washington Street in downtown Phoenix and East McDonald Drive in Scottsdale. Between them and the freeway loops, we reach the East Valley, the West Valley, and the north side up through Anthem and Cave Creek. Calls are answered 24/7 at (602) 878-3594, and visits are scheduled by urgency, with active leaks during storms handled first. Longer projects such as re-roofs are planned around weather, permits and HOA approvals.
Many Valley cities require a permit for a full re-roof, and the process differs from one city to another. We check the rules for your address and pull permits when the work calls for it. If you live near the county line toward Queen Creek or San Tan Valley, our Pinal County roofing page covers that side of the metro. Wherever you are in the county, a spring inspection before monsoon season is the best way to keep a roof ahead of the summer storms.

Homes with concrete or clay tile built in the 1990s and early 2000s across Maricopa County are the main group now reaching underlayment age, typically 20 to 25 years in Valley heat. Older tile roofs that were never re-felted are often past due. Lifting tiles in several spots tells us for certain.
