What does a shingle roof cost to replace in Phoenix?

What moves your number: the size and pitch of the roof, whether the old roof comes off or a new one goes over it, what the decking looks like once it is exposed, and whether the crew is employed or day-rate.

Start here: in this valley, you have the minority roof

Side by side on the two systems, what fails on each, and the mid-life option only tile roofs have: tile vs shingle in the Phoenix climate.

No cost page will tell you this, and it changes how you should read all of them.

There is no Valley-wide dataset of roof materials. The Maricopa County Assessor's residential master file does not publish roof material, and we could not find a tile-versus-shingle share for any Valley city except one. The City of Mesa publishes its building permit records as open data, and the descriptions in those records are searchable.

Tile appears roughly 6.4 times as often as shingle. The most repeated builder description in the file is "CONCRETE TILE ROOF OVER PRE-ENGINEERED WOOD ROOF TRUSSES," recurring across Blandford, Maracay, Woodside, KB Home and AV Homes master plans.

The caveat matters. These count permit records containing the term, and those records are overwhelmingly new construction. They evidence what was installed — they do not measure reroof volume, and they are Mesa only. Anyone quoting a Valley-wide tile percentage is quoting something we could not find published.

Two things follow for you. The cost pages ranking for your search are national pages, built for a shingle-dominated market's crew availability, material supply and competitive pressure — none of which is automatically true here. And a lot of local roofing expertise is pointed at tile, because that is what the Valley's builders installed. That is not a reason to worry. It is a reason to ask a bidder how much steep-slope asphalt work they actually do, and for recent addresses.

Every published shingle figure, side by side

Roof Cost Data's row is the only one in the set that says what job it is pricing — a stated roof size, a stated shingle grade, and tear-off included. Every other row is a number attached to the words "roof replacement" and nothing else.

Finding one: Angi's "Phoenix" per-square-foot range is its national range, unchanged

The per-square-foot range did not move. Not the floor, not the ceiling. At the number a homeowner actually multiplies by their roof size, the localization adds nothing at all. The averages differ, so something was applied to something — whatever it was, it stopped short of the figure most readers will use.

There is a second oddity. The national range spans nearly eight to one. The Phoenix range spans under two to one. A national figure should be wider than a metro figure, because it contains more markets, materials and roof sizes. Instead the metro page has quietly dropped the top of the distribution, and neither page explains the difference or names the other.

We set out the wider pattern — three Phoenix roofing sites reproducing Angi's Phoenix figures as their own, and two materials with different labor profiles priced identically to the dollar — on the Arizona roof replacement cost guide.

Finding two: one source in the whole set publishes a sample size

If a page tells you what the average roof costs, the fair question is: average of what?

Of every roofing cost source we checked, exactly one publishes a number of observations. Angi's national page says it surveyed over 30,000 real Angi customers. That deserves credit for existing.

The others: Angi's Phoenix page says it surveyed "thousands," vaguer than its own national page four months earlier. HomeGuide says it tracks "millions of estimates" — no count, no period, no geography. Fixr publishes nothing. This Old House attributes its Arizona figures to RSMeans/Gordian estimating data, which is construction cost modeling for the whole state, not measurements of Valley jobs. Roof Cost Data describes its own figure as a construction — a "1.05x local cost index for Phoenix" applied to a base — and says so on the page, to its credit. Instant Roofer's Phoenix page carries "Powered by AI" in its own title while the body attributes its figures to "contractor pricing inputs plus roof measurements," with the method itself never disclosed. And LookupCost says outright that its Phoenix figures are "estimates synthesized from public market data using AI research."

And one Phoenix cost source states it outright: its figures are "estimates synthesized from public market data using AI research," with a footer reading "Built with AI agents. Data updated weekly. All costs are estimates." We do not publish that site's dollar figures at all, because by its own description they are not observations of anything.

One sample size in the entire category, and at least two sources describing their own numbers as generated rather than gathered. None of this is fraudulent. It is just far thinner than the confident headline formatting suggests.

Tear-off or overlay — the question none of those pages answer

Tear-off. The existing shingles come off to the deck. The decking gets inspected and repaired, new underlayment goes down, new flashing goes in, new shingles go on. You find out what is under there, which is the point.

Overlay, or recover. New shingles go over the existing layer. Faster and cheaper, because removal, disposal and decking repair all disappear from the invoice.

Overlay is not fringe — it is written into Valley code. Surprise exempts from permit "Re-roofing with the same type of material as the original roofing and provided not more than two layers of asphalt shingles are applied over an existing asphalt shingle roof." A jurisdiction only writes a two-layer limit into an exemption list because the first layer is common.

Here is the problem with the pricing pages. Not one of the seven sources above states which of those two jobs its number describes, except Roof Cost Data, which says tear-off. So the $3 floor and the $11 ceiling may not be two ends of one market. They may be two different jobs, with a scope gap underneath the price gap.

Ask every bidder to write "tear-off" or "recover" on the quote, in those words. Then: how many layers are up there now, and what happens to the price if the decking is bad. A quote with no line for decking replacement has not priced the thing most likely to change your final number.

Heat, UV and how long asphalt lasts here — the honest version

You will see confident numbers on this. We are not going to give you one.

What is published about the climate. The Arizona State Climate Office gives normal maximum temperatures for Phoenix of 103.9 °F in June, 106.6 °F in July and 104.5 °F in August, and notes that sunshine "averages 86 percent of possible," reaching 94 percent in June. Two caveats we will not skip: that temperature record covers 1971–2000, which is stale, and the same source publishes no annual count of days over 100 or 110 °F — so we are not publishing one either.

What is published about roof color. DOE and Oak Ridge National Laboratory guidance on cool roofs states that light-colored roofs "typically reflect 55 to 90%" of sunlight against 5 to 20% for dark roofs, and that a cool roof "could stay more than 50 °F (28 °C) cooler." That document is from July 2010 — old, and worth flagging — but it is why shingle color is a specification decision here, not a taste decision.

What is not published anywhere we could find it: an Arizona-specific service life for asphalt shingle. Not from a manufacturer, not from a trade body, not from a state agency. Manufacturers publish warranties, and a warranty is a commercial term with conditions, not a measurement. GAF's synthetic underlayment data sheet offers "up to a Lifetime Limited Warranty" — conditional on GAF Lifetime shingles plus two qualifying GAF accessories. That is a system-purchase condition, not a statement about survival on a roof in Mesa.

So if someone tells you asphalt gets "about fifteen years in this sun," ask where that is published. There is no published answer, and a number nobody can source is a number somebody made up.

The related absence applies to every pitched roof here regardless of covering: no manufacturer publishes a service life for roofing underlayment either. We checked four. They publish a warranty, a maximum UV-exposure window and a temperature rating — three things routinely misread as a lifespan. Full documentation on the roof underlayment guide.

Permits: in most of the Valley, you probably do not need one

Seven of the eight Valley jurisdictions we checked exempt a same-material reroof from permit, each through an exemption list in their own adopted §105.2. Phoenix's reads: "Roof covering replacement or roof recover with the same type of material as the original roofing." Mesa allows "the same roof material type or better." Chandler's turns on the replacement covering's classification being "equal to or greater than the existing." Maricopa County, Gilbert and Surprise publish their own versions.

Scottsdale is the exception, and its trigger is structural. Scottsdale requires a permit "if any part of the roof sheathing or structural framing is either repaired and/or replaced," with three inspections: roof sheathing, flashing and felt, and final. On a shingle tear-off, finding bad decking is routine — so the same job can be exempt in Phoenix and permitted with three inspections in Scottsdale. Worth knowing when a bidder tells you no permit is needed anywhere in the Valley.

Full code language and .gov sources for every jurisdiction are on the Arizona roof replacement cost guide.

We do not publish a permit fee figure anywhere on this site. We could not verify a fee schedule against a primary city document, and the fee numbers on competitor pages carry no source at all. One aggregator lists an average "permit fee" for a roof project in a city that exempts most reroofs entirely.

When shingle is the right call, and when it is not

Shingle is often right when your roof is already shingle and the structure was built for it — a same-material reroof is the cheapest path through code and the least likely to surprise you. It is right when the pitch and geometry are straightforward, which is where asphalt is at its most economical. It is right when your horizon in the house is shorter and defined. And sometimes it is right because matching stock for an existing tile profile simply does not exist.

Tile tends to be right when your roof is tile now. Changing material is a replacement by definition, it takes you out of the same-material permit exemption in most Valley jurisdictions, and it discards a covering that may still have decades in it. It is especially right when the tile is intact and only the underlayment is finished — the most common tile situation here and the most commonly mispriced, because the correct job is often a lift-and-relay, and seven of nine published Phoenix tile sources do not price that separately. That is the subject of the tile roof cost guide. And if tile was original to the house, the structure already carries the weight; adding tile to a house that never had it is a question for an engineer, not a roofer.

If your roof is low-slope rather than pitched, neither of these is your page — and it is not our job either. We install tile and shingle. We do not do foam or other low-slope membrane systems, and we would rather tell you that here than at the end of an appointment. Someone else is the right phone call.

We install tile and shingle roofing. We do not install foam or metal, and we will tell you that on the phone rather than after a site visit.
