A Scottsdale roofing permit question has one reliable answer
Whether you need a Scottsdale roofing permit depends on the specific work, and the only reliable way to settle it is to ask the city about your job. That is not evasion: the city’s own published homeowner guide on re-roofing cites the 2003 International Residential Code, while Scottsdale now works to the 2021 edition.
We are not willing to restate a decade-old document as current rule, and you should be wary of any website that does. What follows is what can actually be established from sources, clearly separated from what cannot, so you know which questions you still need to ask.
This article covers the current code position, what the city’s older guidance says and how much weight to give it, what Phoenix publishes for comparison, who carries the responsibility, and the specific questions worth asking when you call.
The current code edition is established
One part of this is settled and current rather than inferred. Scottsdale adopted the 2021 International Residential Code, along with the 2021 International Building Code and the 2021 International Energy Conservation Code, plus the 2020 National Electrical Code and a set of 2021 fire, plumbing, mechanical and gas codes.
Those took effect on January 1 and January 7, 2023 (City of Scottsdale). That much is current and sourced from the city’s own codes page rather than from a secondary account of it.
What the page we fetched did not say is whether an adoption of the 2024 code editions is pending. If you are planning work some months out, that is worth confirming, because code editions change what is required rather than merely renumbering it.
The city’s homeowner guide is useful but dated
Scottsdale publishes a “Citizen’s Guide to Re-Roofing Your Home”, and it is genuinely informative about how roofing works and what the city expects. It also cites the 2003 IRC and gives a contractor regulator web address that has since changed, so it is plainly an old document still hosted by the city.
What it says about permits is that a building permit is required if any part of the roof sheathing or structural framing is either repaired or replaced. It lists the inspection stages for a reroof as roof sheathing, flashing and felt, and final.
It also sets out covering-specific positions: tile may go over an existing covering only with plan review approval, structural data, and a slope of 4:12 or greater; built-up roofs are generally fully removed; and a maximum of one asphalt shingle overlay is permitted over one existing shingle roof.
Treat all of that as the city’s published guidance rather than as the rule governing your job. It tells you the shape of what the city cares about, which is useful when you call, and it does not tell you the current requirement.
One widely repeated claim is not in the document
You will find it stated across the internet that a re-roof using the same material needs no permit in Scottsdale. That claim appeared to us only in a search-engine summary. It is not in the text of the city’s handout, and we have found no city page that says it.
We are therefore not repeating it, in either direction. We do not say it is true and we do not say it is false, because we have no source either way, and a permit question answered wrongly is expensive in a way that an article cannot make good.
If someone tells you your job is exempt, ask them to point at the city document that says so. That request is reasonable, and the answer to it is informative regardless of which way it goes.
Phoenix publishes an exemption list, with its own caveat
For comparison, the City of Phoenix publishes a “Work Exempt from Permit” document whose item 16 exempts re-roofing with the same type of material as the original roofing, provided not more than two layers of asphalt shingles are applied over an existing asphalt shingle roof.
The caveat is the revision date. That document is marked rev. 07/14, so it is a 2014 revision, and it should be confirmed against current Phoenix requirements before anyone relies on it (City of Phoenix).
More importantly, Phoenix is not Scottsdale. Each municipality adopts and amends codes separately, so a Phoenix exemption tells you nothing about a Scottsdale requirement. It is included here because people search for both, not because one answers the other.
We have not fetched the reroof permit rules for Mesa, Chandler, Gilbert or Tempe, so we say nothing about them. If your property is in one of those cities, ask that city.
The underlayment-only question is genuinely unresolved
A common and reasonable question here is whether replacing tile underlayment, with no work to sheathing or framing, requires a permit in Scottsdale. We have not been able to resolve it from a current city source, and we are not going to guess.
The older handout ties the permit trigger to sheathing and structural framing work, which on its face suggests underlayment-only work might sit outside it, but that document predates the current code and the inference is ours rather than the city’s.
Because underlayment replacement is one of the most common substantial roof jobs in this area, this is exactly the question to put to permit services directly before work starts. Replacing tile underlayment covers what that job involves and what drives its cost.
The property owner carries the responsibility
The city’s guide is clear on one point that does not depend on code edition: reroof permits may be obtained by the homeowner or by a licensed contractor, and the property owner is ultimately responsible for ensuring that a permit is issued.
That responsibility does not transfer with the job. If a contractor says a permit is unnecessary and the city later disagrees, the owner is the one holding the problem, which is a good reason to verify rather than delegate the question.
Ask any contractor, in writing, whether a permit is being pulled for your job and who is pulling it. Put the answer in the contract alongside the scope. How to check a roofing contractor in Arizona covers what else that written agreement should carry.
Inspections are part of the process, not an obstacle
Where a permit applies, the inspection stages are the mechanism by which the work gets checked at the points where it can still be seen. The city’s guide lists sheathing, flashing and felt, and final, which maps onto the moments when the layers that matter are exposed.
The flashing and felt stage is the useful one for a homeowner to know about, because it is the only point at which the underlayment and the flashing details are visible to anyone other than the roofer. After that they are covered for twenty years or more.
Ask when each inspection is scheduled and whether you can be present for it. A contractor who welcomes that question is telling you something useful about how they work, and so, rather more loudly, is one who does not.
Permit fees are not published here
We have not retrieved a current fee schedule from the city, so no figure appears anywhere in this article and none should be inferred from it. Anyone quoting you a specific permit cost from a website rather than from the city is working from exactly the same position we are, which is to say without a source.
Fees are also only part of the timing question. Processing time, whether plan review is triggered, and inspection scheduling all affect how long the work takes, and those are worth asking about at the same time as the cost.
If your project involves a rebate with a deadline attached, that interaction matters. Cool roofs in Scottsdale and the SRP rebate covers a programme with both an installation deadline and a submission window, and a permit delay eats into both.
Documentation outlasts the job
Keep the permit, the inspection records and the final sign-off together with the rest of your roof paperwork rather than filing them separately. That record matters at resale, it matters for warranty claims, and it matters a great deal if a dispute with a contractor develops later.
Arizona law allows a complaint against a licensed contractor to be filed with the Registrar of Contractors within two years after the project is completed (Arizona Revised Statutes 32-1162). Permit and inspection records are part of what makes such a complaint evidenced rather than asserted.
A roof with a documented permit history is also simpler to sell, because a buyer’s questions have answers rather than gaps.
That is worth bearing in mind if the temptation arises to skip the process on a job nobody would notice. Unpermitted work has a way of surfacing at the least convenient moment, usually during a sale or a claim, and resolving it retrospectively is considerably harder than doing it in order the first time.
Where to start
Call Scottsdale’s permit services and describe your actual job: the roof type, exactly what is being replaced, and whether any sheathing or framing work is anticipated. Ask whether a permit is required, whether plan review applies, and what inspections will be scheduled.
Do that before signing a contract rather than after, because the answer can change the scope and the programme. Ask the contractor the same questions separately, and note any disagreement between the two answers, because that disagreement is itself useful information.

Frequently asked questions
These are the questions homeowners here ask most often about roofing permits, and several of them are answered below by telling you who to ask rather than by guessing at something we cannot source. Each one should be confirmed with the city for your own specific job.
Do I need a permit to replace a roof in Scottsdale?
It depends on the work. The city’s published homeowner guide ties the permit trigger to repair or replacement of roof sheathing or structural framing, but that guide cites the 2003 code while Scottsdale now works to the 2021 edition. Confirm your job with permit services.
Does replacing tile underlayment alone need a permit?
We could not resolve this from a current city source, so we do not answer it. The older guidance points at sheathing and framing as the trigger, but that is an inference from a dated document. This is the question to put to the city directly.
Which building code does Scottsdale use?
Scottsdale adopted the 2021 International Residential Code, the 2021 IBC and IECC, the 2020 National Electrical Code and a set of 2021 fire, plumbing, mechanical and gas codes, effective in January 2023. Whether a 2024 adoption is pending was not stated on the page we read.
Can a homeowner pull the roofing permit themselves?
The city’s guide says reroof permits may be obtained by the homeowner or a licensed contractor, and that the owner is ultimately responsible for making sure a permit is issued. That responsibility stays with the owner regardless of who applies.
Is Phoenix the same as Scottsdale for roofing permits?
No. Each municipality adopts and amends codes separately, so a Phoenix exemption says nothing about a Scottsdale requirement. Phoenix publishes its own exempt-work list, but the version we read is a 2014 revision and should be confirmed as current.
What inspections happen on a permitted reroof?
The city’s guide lists roof sheathing, flashing and felt, and final. The middle one is worth knowing about, since it is the only point at which the underlayment and flashing details are visible before being covered for decades.
