A plain-English starting point for roofing contractors. This is general Arizona guidance — fees, forms, and timelines are set by each city.
Short answer
Re-roofing with the same material is exempt from permits in the Phoenix-area jurisdictions we've checked: Phoenix, Scottsdale, and unincorporated Maricopa County exempt same-material roofs, and Mesa exempts a new covering of equal or greater classification. Changing materials — like shingle to tile — or repairing roof sheathing or framing generally needs a permit. The work is done by an ROC-licensed roofing contractor.
The general picture
Roofing is where Phoenix-area jurisdictions mostly agree: replacing a roof with the same material doesn't need a permit. Phoenix, Scottsdale, and unincorporated Maricopa County exempt same-material re-roofs, and Mesa exempts a new covering of equal or greater classification. What changes the answer is weight and structure — moving from shingles to tile, replacing sheathing or framing, or adding overlays. Historic homes can need separate design approval. See the verified notes for Phoenix, Mesa, Scottsdale, and unincorporated Maricopa County.
Typically needs a permit
Switching roofing materials (for example, shingle to heavier tile), repairing or replacing roof sheathing or structural framing, adding overlays where the jurisdiction limits layers, and roofs on historic properties that may need design approval.
Usually doesn't (general norm)
- Replacing the roof covering with the same material — or, in Mesa, with a covering of equal or greater classification
- Minor repairs and patching
Documents & plans generally required
- Re-roof permit application where a permit is required
- ROC license number and class, plus city and state tax license numbers where the application asks
- Scope: tear-off or recover, existing and new materials, and roof slope
- Structural information when moving to a heavier material like tile
- Underlayment and fire classification of the new roof covering
- Any mechanical, plumbing, or gas penetrations the work affects
Common reasons reroof applications get bounced
Code-rooted patterns across Arizona — not a city-specific rejection rate.
- Heavier material such as tile proposed without structural information
- More overlay layers than the adopted code or local handout allows
- Roof covering classification lower than required
- Sheathing replacement left out of the scope
- Work on a historic property started without design approval
The inspection sequence
A typical order — the number of stops and exact sequence vary by jurisdiction and scope.
- 1Sheathing or in-progress inspection where decking is replaced and a permit is required
- 2Final inspection
Licensing — who can pull it
Re-roofing in Arizona is done by an ROC-licensed roofing contractor — R-42 (residential), CR-42 (dual), or C-42 (commercial). The roofing classification allows replacing up to 10% of the roof deck; duct changes must be subcontracted to the proper trade.

Frequently asked questions
Do I need a permit to re-roof in Arizona?
Not for a same-material replacement in the Phoenix-area jurisdictions we've checked. Changing materials generally needs a permit — Phoenix requires one when the roofing material changes — and structural repairs such as replacing sheathing or framing typically do too, so confirm with the city.
Can I roof over existing shingles?
Limits on overlays come from the adopted residential code and local handouts. Mesa's re-roofing guide calls for a tear-off when there are two or more layers, the covering is water-soaked, or the deck is unsafe. Check the local handout before quoting a recover.
Who can do a re-roof in Arizona?
An ROC-licensed roofing contractor (R-42, CR-42, or C-42).
