The Best Roofing Contractors in Phoenix, AZ, Compared

It depends on the roof's size, pitch, number of layers to remove, decking condition and the material you choose. In Phoenix, concrete or clay tile over new underlayment are the most common replacement, with foam (SPF) and elastomeric coatings on flat roofs as the step-up option. Get at least two itemized written estimates from the contractors on this page; a serious estimate lists the underlayment, flashing, ventilation and decking price per sheet, not just a lump sum.

In most of Maricopa County a full replacement requires a building permit and at least one inspection; small repairs often do not. The contractor should pull the permit in their name. If a roofer asks you to pull it as the homeowner, treat that as a warning sign about their license or insurance.

Phoenix is tile and flat-roof country. Underlayment replacement under existing tile is the most common job, and monsoon leaks drive the repair calls. The region's usual problems are extreme heat and UV, monsoon downpours and wind and thermal cracking on flat roofs. Monsoon season (July through September) finds every weak point in a flat roof. Coatings and tile underlayment are the maintenance items; the tile itself usually outlasts the house.

Most roof work here is maintenance rather than a storm claim, so compare cash prices carefully and ask for the coating's warranty in writing. Document everything with photos before any work starts, and never sign an assignment of benefits or a contract contingent on an insurance approval without reading it.

Ask for the certificate of insurance directly from the insurer, not a copy from the contractor, and confirm it lists both general liability and workers' compensation. Look the license up on the Arizona contractor licensing board site, and check the local address matches what the board has on file.
