What a full roof replacement involves, step by step
Replacement begins with a tear-off, not an overlay. We strip the old asphalt shingle, roofing felt, and tar paper down to the sheathing, then inspect the roof deck before anything new goes on top.
- A tear-off crew removes every layer down to the deck, and all debris goes into a dumpster parked at the curb.
- Soft or delaminated plywood and OSB sheathing gets replaced, because new shingles laid over rotten decking telegraph every low spot.
- We fasten synthetic underlayment with a nail gun and set a self-adhered ice-and-water shield along valleys, eaves, and pipe boots.
- Drip edge goes on at the eave and rake, then step flashing, counter-flashing, chimney flashing, and pipe flashing seal walls and penetrations.
- Field course shingles go down in staggered courses over a starter course, with a cut valley and a capped ridge topped by a ridge vent.
- Fascia, soffit, gutter, and downspout work finishes the job, and we register the manufacturer warranty in your name.
Materials we quote, and why we quote them
Material choice drives both the cost and how long the roof lasts under Phoenix sun. We quote what fits your pitch, your budget, and the structure underneath.
- Architectural shingles from GAF Timberline, Owens Corning Duration, or CertainTeed Landmark are the standard for sloped residential roofing, with a heavier mat and better wind uplift than a three-tab shingle.
- Concrete tile and clay tile suit Spanish-style rooftops, but they are heavy, so we check the truss and rafter load before we bid.
- Standing-seam metal panel and corrugated panel shed heat and rain well on low-slope sections and hold up for decades with minimal upkeep.
- TPO, EPDM, PVC membrane, modified bitumen, and built-up roof systems cover flat roofing where ponding water is the real enemy.
- Wood shake and cedar shake still sit on older homes; we match what we can and say plainly when replacement beats repair.
What our roof inspection actually looks for
We walk the rooftop, check the attic, and photograph what we find. Water rarely announces itself; it wicks along the decking and shows up as a ceiling stain three rooms away.
- Granule loss and bare asphalt on south-facing slopes, where UV breaks down the bitumen first.
- Curled, split, or missing shingles, plus bruised shingles from hail that dent the mat without tearing it.
- Rotted sheathing and fascia, cracked caulk and mastic at flashing beads, and rusted or overdriven fasteners.
- Sagging rooflines, ponding water on flat sections, and gutter seams that peel apart during monsoon season.
- Failed pipe boots and vent boots, worn ice dam protection at the eave, and daylight showing through soffit vents.
Phoenix conditions that change the work
Phoenix averages about 111 days a year at or above 100 F. Sustained heat oxidizes asphalt shingles and dries tile underlayment from below, which is why we replace it even when the tile itself looks fine.
Hail is a recurring monsoon risk here. The 2025 season damaged more than 500 homes in Tempe alone, so we tarp and document before we ever quote storm damage.
Timeline, cost drivers, and insurance
A typical single-family tear-off and re-roof runs one to three days for shingle and longer for tile. Cost moves with square footage, pitch, how many layers come off, and how much decking needs replacing.
Building code in Maricopa County governs underlayment and fastener schedules, and we pull the permit where one is required. When a storm did the damage, we document the roof and stay with your insurance claim from the adjuster inspection through the final scope.
