Do You Need a Permit to Replace a Roof in Phoenix?
Not if you put back what was there. The 2024 Phoenix Building Construction Code, in effect since August 1, 2025, exempts roof covering replacement or roof recover with the same type of material as the original roofing. The city's Residential Single-Family Construction Permit Guide says the same thing in homeowner terms, re-shingle or re-tile roof with same material needs no permit, and adds the one limit that matters for shingle roofs: no more than two layers of asphalt shingles may be placed over an existing asphalt shingle roof. The same guide lists what does need a permit: roofline extensions and replacing wood or asphalt shingles with a tile roof. Tile is several times heavier than shingle, which is why the city's valuation guide describes that job as a change to tile with structural upgrade; the framing has to be checked and usually strengthened, and that means plans and a plan review.

How Much Does a Roof Permit Cost in Phoenix?
Nothing for a same-material re-roof. When a permit is required, the 2026 Development Fee Schedule (Appendix A.2, effective January 20, 2026) prices it on valuation. The city's Miscellaneous Construction guide values residential roofing two ways: tear off and replace at $1.64 per square foot for shingles, and change asphalt to tile with structural upgrade at $9,200 plus. Take a 2,000-square-foot roof that is changing material without structural work: 2,000 x $1.64 = $3,280 of valuation. Table A charges $195 on the first $1,000 plus $12 per additional $1,000 or fraction, so the permit fee is $195 + 3 x $12 = $231, and because the valuation is under $5,000 a counter review of 15 minutes or less carries no plan review fee. A shingle-to-tile conversion starts at $9,200: the permit fee is $195 + 9 x $12 = $303, and since the valuation exceeds $5,000 and plans are reviewed, the residential plan review fee of 100% of the permit fee adds $303, about $606 in all. If your contract price is higher than the city's calculation, the higher number sets the fee.
What a Tile Conversion Requires
The city's plan submittal checklist wants an approved evaluation report number and manufacturer for all concrete or clay tile roofing, all roof slopes noted, and complete framing plans showing the size, spacing and span of trusses, rafters and beams, with truss calculations sealed by an Arizona-registered engineer. Because the structural upgrade is the point of the permit, expect the reviewer to ask for an engineer's evaluation of the existing framing. At inspection, a tile roof must be loaded, meaning tile installed or piled on the roof, before the pre-drywall or framing inspection is signed off, and the truss calculations must be on site.
Who Pulls a Roofing Permit
Residential permits go through the SHAPE PHX portal. Roofing contractors are licensed by the Arizona Registrar of Contractors, and the contractor's ROC number goes on the permit; an owner who will occupy the home may do the work under ARS 32-1121.A.5, the exemption printed on the city's application. Every permit expires 24 months after issuance. Re-roofing without a required permit costs an investigation fee of at least $250 plus double the permit fee.
