Roof Replacement in Phoenix, AZ
A new roof is one of the largest single expenses a homeowner takes on. Before you spend it, you should know whether you need it.
Many Phoenix homeowners who’ve been told they need a full replacement actually need an underlayment replacement — a job that keeps their existing tile and costs substantially less. We’ll tell you which category you’re in before we quote anything.
Get a Second Opinion Before You Commit
If another contractor has told you that you need a full roof replacement, get a second look before signing. It costs you nothing and takes about an hour.
We inspect, photograph, and give you a written assessment. If the first contractor was right, we’ll tell you so and quote it competitively. If the roof actually needs an underlayment replacement or a repair, we’ll tell you that instead — and quote that.
When You Genuinely Need a Full Replacement
- The roofing material itself has failed not just the layer beneath it. Widespread cracking, spalling, or delamination on concrete tile. Curling, blistering, and bare granule loss across a shingle roof.
- Extensive deck damage. Once sheathing replacement passes a certain share of the roof, a full replacement is usually the better value.
- Your shingle roof is past 20 years.** Asphalt shingle in Arizona UV rarely delivers its nominal rated life — a 30-year shingle here often performs like a 15-to-20-year product.
- A failing foam or built-up roof past recoating. Foam can be recoated several times, but there’s a point at which the base has taken too much water intrusion.
- You’re changing systems. converting a low-slope section to foam, or moving from shingle to tile or metal.

Roof Systems We Install
Tile
Concrete and clay. The Valley standard for good reason: 50+ year material life, strong UV and thermal performance, and it looks right on Southwest architecture. Highest upfront cost, best long-run value.
Shingle
Architectural asphalt shingle. Lowest upfront cost and fastest install. Realistic Arizona service life of 15 to 22 years — plan on the lower half of the manufacturer’s rating, because UV here is brutal on asphalt.
Foam (SPF)
Sprayed polyurethane foam for flat and low-slope roofs. Seamless, self-flashing, and adds meaningful R-value — which matters on a Phoenix cooling bill. Requires recoating roughly every 5 to 10 years, and with that maintenance it lasts decades.
Metal
Standing seam and exposed fastener panels. Excellent longevity, high wind resistance, minimal maintenance. Common on rural properties, shops, and outbuildings.
Our Replacement Process
- On-site measurement and inspection We measure the roof, assess the deck, check ventilation, and photograph existing conditions. No phone quotes.
- Written proposal with options: Where more than one system makes sense for your home, you get pricing on each with the tradeoffs explained plainly.
- Permitting: We pull the required permits. Included in the scope.
- Tear-off and deck inspection Old system removed to bare deck. Every square foot inspected; rotted sheathing replaced.
- Deck prep and underlayment. New underlayment, valley metal, drip edge, and all flashings. Flashings are always new — never reused.
- Roof system installation to manufacturer specification, so the material warranty stays valid.
- Ventilation check. Inadequate attic ventilation cooks a roof from underneath and shortens its life. If yours is undersized, we’ll say so and quote the correction.
- Cleanup, magnetic nail sweep, final walkthrough, and warranty documentation.
Typical timeline: 2 to 4 days for shingle, 4 to 8 days for tile, 2 to 5 days for foam.

Frequently Asked Questions
Two to four days for shingle, four to eight days for tile, two to five days for foam. Weather and roof complexity shift the range.
No. It’s loud, and there will be crews and equipment on site during working hours, but the interior of your home stays intact and habitable.
Tile: 50+ years for the tile itself, with underlayment replacement due at roughly 20 to 25 years. Architectural shingle: realistically 15 to 22 years here. Foam: decades, with recoating every 5 to 10 years. Metal: 40 to 70 years.
Only when a covered event — storm, fire, or similar sudden damage — caused the failure. Age-related wear is excluded under standard policies. We document conditions thoroughly, and that documentation supports a claim if one applies.
We don’t recommend it and generally won’t do it. Overlays hide deck damage you’d otherwise catch, add weight, trap heat, and void most manufacturer warranties.
Yes. Permitting is included in our scope and pricing.
Yes. See financing options.
