Roofing specifications and per-square price ledger

Unit rates, material compositions, and wind tolerances for residential and commercial roofs across Phoenix and Maricopa County. Inquiry estimates only; written quotes follow on-site measurement.

Direct unit pricing disclosed before physical inspection

Contract pricing avoids vague lump-sum totals with hidden allowances, breaking down clearly by square feet and roofing squares (100 sq ft).

The final price on any roof in Phoenix depends strictly on verified variables: total surface square footage, roof pitch factor, material dead load, tear-off layers, accessibility, and the condition of the structural plywood decking. Below is our transparent unit pricing ledger across all core trades.

Full roof replacement and structural deck tear-off

Verified Rate: $4.00–$11.00 / sq ft • $475–$1,050 / square

Every roof replacement begins with the absolute removal of all existing roofing materials down to the structural plywood sheathing. In the Phoenix desert, standard asphalt shingles and underlayment disintegrate when trapped beneath additional layers. Contractors who nail second layers over aged shingles void factory warranties and conceal severe structural rot.

Our crews strip old shingles or tiles, pull every stray nail, and inspect each 4×8 sheet of CDX plywood or OSB decking. Any sheet showing water delamination or dry rot is cut back and replaced. We install 26-gauge galvanized drip edge along all eaves and rakes with sealed seams before any waterproofing goes down.

Removal Depth Bare structural timber decking (no overlays permitted)
Decking Standard 1/2-inch or 5/8-inch CDX / OSB structural sheathing
Perimeter Metal 26-gauge galvanized eave and rake drip edge
Site Protocol Heavy tarps, ground shielding, daily continuous magnetic nail sweep
Clean structural CDX plywood decking exposed after complete roof tear-off
Residential roof tear-off in progress showing clean structural sheathing ready for nail inspection.

Architectural dimensional asphalt shingles

Verified Rate: $4.50–$7.00 / sq ft • $399–$580 / square

Standard 3-tab shingles fail prematurely in the Salt River Valley due to severe thermal baking and 50 to 70 mph monsoon gusts. We install heavyweight architectural dimensional composite shingles built with dual fiberglass reinforcement mats and ceramic granules formulated to resist ultraviolet degradation and copper-banded algae discoloration.

Every shingle course is fastened using a 6-nail high-wind pattern rather than standard 4-nail residential minimums. We place self-sealing SBS-modified starter shingles along all eaves and rakes so summer deck heat bonds the factory adhesive strips against monsoon gusts.

Shingle Class Heavyweight fiberglass architectural dimensional
Fastener Spec 6-nail high-wind mechanical fastening pattern
Adhesive System Thermally activated SBS starter and course sealant strips
Dead Load Weight 240 lbs per roofing square
Architectural dimensional shingles installed in staggered courses with high-wind fastening line

Concrete and clay tile systems with underlayment reset

Verified Rate: New Tile: $7.00–$12.00 / sq ft • Lift & Reset: $4.00–$7.00 / sq ft

Concrete tiles outlast the underlayment underneath them by decades. Attic heat exceeding 165°F bakes standard 30-pound organic felt until it cracks and turns into dry dust. When monsoon rain drives past the tile laps, water runs straight through the split felt into the attic.

Our tile lift-and-reset procedure preserves sound concrete tiles and skips unnecessary material replacement. Crews lift existing tiles, inspect each piece for cracks, and stack sound tiles in pallets on the roof. We strip dried felt down to bare plywood decking, replace damaged sheets, and roll dual-layer SBS-modified self-adhering synthetic membrane rated to 250°F before resetting the original tiles with corrosion-resistant fasteners and fresh mortar bird-stops.

Underlayment Dual-layer self-adhering SBS synthetic membrane (rated to 250°F)
Fastening Spec Hot-dip galvanized or stainless steel screws with neoprene washers
Eave Enclosure Custom galvanized eave risers and vented mortar bird-stops
Structural Load 950 lbs per roofing square (requires verified truss integrity)
High-temperature self-adhering SBS synthetic underlayment smoothed onto bare roof decking
Roofer rolling dual-layer SBS-modified underlayment rated to withstand 250°F continuous desert heat.

Standing seam structural metal roofing systems

Verified Rate: $8.00–$16.00 / sq ft • $800–$1,600 / square

Standing seam metal roofing is the premier long-term defense against extreme desert thermal cycles. In Phoenix, ambient temperatures shift up to 45°F between midday sunshine and desert nights, causing metal panels to expand and contract constantly. Exposed-fastener metal roofs fail because screw holes wallow out and rubber washers dry-rot under intense UV radiation.

Heavy 24-gauge structural steel standing seam panels feature concealed expansion clips and mechanical double-lock seams. The panels float naturally over the roof deck during thermal expansion without fatiguing fasteners or stressing the substrate, finished in factory fluoropolymer resin coatings built for desert UV exposure.

Steel Specification 24-gauge structural steel or heavy-gauge aluminum
Fastener System Concealed floating thermal expansion clips (zero exposed screws)
Seam Profile 1.5-inch or 2.0-inch mechanically seamed double-lock ribs
Dead Load Weight 120 lbs per roofing square
Parallel standing seam metal roof panels with clean vertical ribs reflecting desert sunlight
Precision mechanical seam locking tool folding 24-gauge steel ribs into a watertight seal.

Commercial single-ply TPO and EPDM flat roof membranes

Verified Rate: $5.00–$12.00 / sq ft • $500–$1,200 / square

Flat and low-slope roof transitions (slopes under 2:12) cannot shed water via gravity like steep roofs. In the Phoenix area, ponding water from monsoon downpours dissolves organic asphalt emulsions and degrades unreinforced single-ply membranes.

Commercial 60-mil Thermoplastic Polyolefin (TPO) and Ethylene Propylene Diene Monomer (EPDM) systems lay over high-density polyiso insulation boards, alongside closed-cell roof foam transitions where sloped parapets meet low-slope decks. TPO laps are hot-air welded and tested to 1,200 psi shear resistance so the seams fuse into one continuous waterproof sheet.

Membrane Gauge 60-mil scrim-reinforced TPO or EPDM single-ply membrane
Seam Welding Automated hot-air fusion welds tested to 1,200 psi shear
Insulation Substrate High-density polyisocyanurate (polyiso) board and roof foam
Dead Load Weight 45 lbs per roofing square
Hot-air heat welding of commercial single-ply TPO roof membrane lap seam

How our on-site inspection and contract process works

From initial inspection to magnetic perimeter sweep, every replacement job follows six fixed field steps.

  1. Physical Roof Inspection: Our roofer climbs the roof to check tile condition, valley flashings, chimney saddles, eave drip edges, and attic ventilation flow.
  2. Unit Price Scope: You receive a written estimate stating roof area, square count, pitch multiplier, material spec, and per-sheet decking replacement rates.
  3. Complete Material Tear-Off: Old materials are stripped down to the structural sheathing and hauled away in our dedicated debris containers.
  4. Substrate Rehabilitation: Any water-damaged or dry-rotted plywood decking is cut back to truss centers and replaced with fresh CDX sheets.
  5. Barrier & Flashing Installation: High-temperature SBS underlayment is rolled out, drip edges are secured, and 26-gauge metal valleys are fabricated.
  6. Final Installation & Cleanup: Shingles, tiles, or metal panels are fastened per high-wind specifications, followed by continuous magnetic property sweeps.
