Arizona Roof Replacement Cost Guide (2025 Update)

Introduction

In this article, I’ll give you the typical costs for installing a new roof in Arizona in 2025, for both residential and commercial buildings. I’ve spent years reviewing contractor bids and researching roofing costs for my clients around the country. The roof cost estimates I provide here were produced by analyzing current material prices, Arizona labor costs, and other relevant factors, including roofing project values from actual Arizona building permit data. The roof systems covered here include asphalt shingles, metal roofing, slate, tile, synthetic composite, cedar shakes, and all of the common types of low-slope commercial roofing.

Roof replacement costs in Arizona tend to be slightly below the national average. Labor rates are generally more affordable than in coastal states, and business operating expenses are somewhat lower, though material costs are in line with the rest of the country. (Compare with national average roof replacement costs.)

Actual roof prices will vary depending on location, roof size, roof slope, complexity, and, of course, the type of roof system installed. Asphalt shingles are by far the most popular residential roof covering in Arizona, but alternatives like standing seam metal, clay and concrete tile, and synthetic composites are also relatively common. Commercial “flat” (low-slope) roofs in Arizona most often use single-ply membranes (EPDM, TPO, and PVC roofing), modified bitumen, or spray-applied polyurethane foam systems.

On average, Arizona residential roof replacement prices in 2025 typically range from around $4.85 per square foot for basic asphalt shingles to around $30 per square foot for high-end copper roofing. This means a typical 1,700-square-foot pitched roof may cost between $8,200 and $51,000, depending on the material selected.

Commercial roofing generally costs less per square foot, with Arizona commercial roof replacement prices ranging, on average, from around $4 per square foot for a ballasted TPO overlay system with no insulation included to around $15 per square foot for a 2-ply modified bitumen system with enough insulation to meet the R-25 to R-30 energy code requirements followed by most Arizona jurisdictions for roofs with above-deck insulation.

The tables below provide cost information for all roof types and systems.

Climate Considerations for Arizona Roofs

Arizona’s climate is among the most diverse in the country, ranging from the hot, arid deserts of the south and west to the high plateaus and mountainous regions in the north and east. Much of the state, including Phoenix and Tucson, experiences a desert climate characterized by extremely hot summers, mild winters, and very low annual precipitation. In contrast, northern and higher-elevation areas such as Flagstaff have a much cooler climate with cold, snowy winters and summer thunderstorms associated with the North American monsoon. Annual precipitation varies widely, from less than 10 inches in the desert valleys to more than 25 inches in some mountain regions.

Cooling degree days far exceed heating degree days across most of Arizona. Reducing cooling energy expense is therefore a significant design factor for roofs in Arizona. White or light-colored reflective “cool roof” products are highly beneficial in the desert regions, lowering cooling costs by reflecting solar heat. In the cooler northern mountains, darker roofing materials can help retain heat during the winter months, although energy savings from this are usually modest compared to the importance of summer cooling performance.

Unlike in more humid environments, roof algae growth is not a widespread concern in Arizona. Instead, ultraviolet (UV) radiation and thermal cycling are the most significant environmental stressors. Roof coverings must be selected for resistance to intense sun exposure, large daily temperature swings, and in some areas, occasional high winds and hail. The annual monsoon season can also bring short periods of heavy rainfall, so proper drainage is essential.

Homeowners and property managers in Arizona should consider the following:

• Asphalt shingles are widely used and cost-effective, but they can degrade faster under Arizona’s high UV exposure than in other areas. Choosing shingles with enhanced UV resistance and manufacturer warranties suited for hot climates is a good idea.
• Ventilation and underlayment are critical in Arizona. Proper attic ventilation reduces heat buildup, helping to extend roof life and lower cooling bills. Quality underlayment is also important to resist heat damage and provide secondary moisture protection during monsoon rains.  Note that improper ventilation can void your roof warranty.
• Tile roofing (clay and concrete) is especially popular in Arizona. Tile performs exceptionally well in hot, dry climates, offers long lifespans, and provides natural ventilation between the tile and and roof deck that helps reduce heat transfer.
• Metal roofing is also an excellent choice in Arizona, particularly when finished with reflective “cool” coatings to reduce heat transfer.
• Slate, cedar, and synthetic composites are far less common but can be effective in northern Arizona’s cooler, wetter regions. In areas prone to wildfire, roofing systems should be Class A fire-rated.
• Insulation and air sealing are critical statewide. Although Arizona does not mandate a statewide R-value requirement, most major jurisdictions follow IECC standards requiring R-25 in climate zones 2–3 and R-30 in zones 4–5 for roofs with above-deck insulation.

Things to Keep in Mind

These roof cost estimates should be fairly accurate; I make an effort to update them regularly using current material prices and labor data specific to Arizona. Keep in mind that the costs listed below are averages, and actual costs can vary significantly depending on your specific location and the size, configuration, accessibility, and condition of your particular roof.

The residential roof cost estimates provided here are for roof replacements on roofs with a 6/12 pitch and include all standard roof components (underlayment, ice & water shield, batten systems, fasteners, flashing, etc.). Steeper roofs or roofs with complex designs can increase costs by as much as 30%.

Removal of an existing commercial or residential roof typically adds between $1 and $3 per square foot. For the estimates in the tables below, $1.50 per square foot for tear-off and disposal has been included in all pricing except for the “no additional insulation” commercial roof pricing, which generally indicates a roof recover project.

For energy code purposes, Arizona does not have a statewide mandated R-value requirement. Instead, requirements are set at the local level, with most major jurisdictions (such as Phoenix, Tucson, and surrounding municipalities) adopting the 2015 or 2018 versions of the IECC. Under these codes, insulation requirements for low-slope commercial roofs with insulation entirely above the deck are:

• Climate Zone 2: R-25 continuous insulation
• Climate Zone 3: R-25 continuous insulation
• Climate Zone 4: R-30 continuous insulation
• Climate Zone 5: R-30 continuous insulation

Because enforcement is local, you should always confirm the applicable requirements with your building department before starting a project.

When performing a roof recover (installing a new roof over an existing one), these insulation requirements typically do not apply. Roof recover projects generally involve installing a layer of cover board over the existing system to provide a suitable substrate, followed by the new membrane. Keep in mind that roof recovery is not always permitted or advisable.

Where the price estimates in the table include R-25 insulation, add $1.00 per square foot for roofs located in jurisdictions that require R-30.
