Service area
Postwar homes, older downtown buildings and East Mesa communities have different roofs. Investigate cooling-equipment openings, low-slope additions and existing layers before choosing a system.
The roofing decision
On a Mesa home, an old cooler curb can remain part of the roof long after the equipment changes. The surrounding deck and flashing need assessment along with the main surface. Downtown masonry and East Mesa manufactured-home roofs introduce different structures and should be described separately in a proposal.
Discuss your Mesa roofIdentify cooler locations, patched openings and equipment curbs. Inspect accessible decking and the transition into the roofing system. The replacement plan should explain how unused penetrations will be closed and who handles any equipment that must move.
Explore roof replacementA manufactured-home roof or separate cover may have different load and installation requirements from a conventional house. Establish the existing construction before choosing materials or a roof-over. Include the connection to carports and patios in the inspection.

The roofs here
Mormon settlers from Utah and Idaho founded Mesa on the mesa in 1878 and reused the old Hohokam canals; the town incorporated in 1883. Downtown and the older neighborhoods around it have early twentieth-century houses and commercial buildings. Expect layered roofs, board sheathing and low-slope sections behind parapets.
Mesa’s central neighborhoods filled with postwar ranch houses: low-pitched shingle roofs, flat roofs over carports and additions, and evaporative coolers on the roof. Where a cooler sits or once sat, check the curb flashing and the deck beneath.
East Mesa grew later, with tile-roofed subdivisions and many manufactured-home and RV communities. Those communities have low-slope metal or membrane roofs and roof-overs, which call for lightweight coatings and careful drainage rather than heavier systems.
Local building patterns help guide an inspection. Your roof’s actual condition, materials and repair history determine the recommendation.
Conditions
Mesa’s summer is as long as Phoenix’s. Rooftop evaporative coolers add water to roofs that are already hot, and leaks at their drain lines and curbs are common. Inspect those points every season the cooler runs.
Monsoon storms that form over the mountains east of the valley often reach east Mesa first, with hail and gusts. Check tile, ridge caps and coatings on the east side of the city after a strong storm.
Canals still run through Mesa, and older neighborhoods are flood irrigated. Combined with roof runoff, that water can sit against walls. Downspouts and grading should carry roof water away.
Mesa’s 2024 International Codes apply to permit applications submitted on or after January 8, 2026. Work already submitted or under construction is not affected. Confirm the edition for a specific permit before specifying the roof assembly.

Mesa adopted the 2024 International Codes, which take effect for permit applications submitted on or after January 8, 2026. Projects already submitted, under review or under construction are not affected, and earlier design to the 2024 codes was allowed through the code modification process.
Mesa’s building code pageMaricopa County is in IECC climate zone 2B, hot and dry. Arizona has no statewide energy code like California’s Title 24: the energy rules for a roof are the ones in the IECC edition the city has adopted, applied in that zone. Building type and roof slope still decide which of them apply to a given project.
The county climate zone guideMaricopa County publishes no special wind region list, so there is no county figure to quote for Mesa; the design wind speed comes from the ASCE 7 maps for the individual site. Look the address up and confirm the figure with the building department. Wind load rises with the square of the speed, so a few miles an hour changes what the fastenings, the perimeter and the edge metal have to carry.

What we do
Ranch houses and coolers point toward shingle and flat-roof work, manufactured-home communities toward coatings, newer subdivisions toward tile.

Before you plan the work
The opening, curb or earlier patch may remain a vulnerable detail after equipment removal. Inspect the accessible deck and flashing, and ask how the area will be incorporated into the replacement assembly rather than simply covered again.
Yes, including the junction with the main roof. It may use a different material and slope. The estimate should identify which sections are included, how each drains and how new work connects to retained roofing.
Do not assume so. Establish the structure, existing assembly and proposed load before selecting materials. A conventional house’s roofing detail is not automatically suitable for a manufactured home or later roof-over.
Check earlier layers, deck condition, parapet caps, wall connections and outlets. The masonry interface and drainage should be included in the scope, alongside the open roof surface and any equipment penetrations.
