Overview

Roofing Estimates From Accurate Roof Measurements

Quick answer: Roofing estimating is the takeoff and pricing of roof systems. The estimator measures roof area by plane and pitch, converts it to roofing squares of 100 square feet, measures ridges, hips, valleys, rakes and eaves in linear feet, counts penetrations, vents and drains, and prices the roofing material, underlayment, insulation, flashings, accessories, tear-off where needed and labor for the specified system.

Arizona roofs work hard. Intense sun, extreme surface temperatures, monsoon winds and hail all test roofing materials. That is why Arizona roofs look different from those in many other states: concrete tile on sloped residential roofs, spray polyurethane foam and single-ply on flat roofs, and reflective coatings on commercial buildings.

Our roofing estimators measure every roof plane from the roof plan, elevations and sections, accounting for pitch, overhangs and complex geometry. Linear items such as ridges, hips, valleys and rakes are measured separately because they use special materials and labor. Commercial roofs include insulation, tapered systems, drains, curbs and flashings.

Roofing packages pair with our Insulation Estimating Services, Solar Estimating Services and, for storm damage, our Xactimate Estimating Services.

Metal roof panels, trims and clips for homes and commercial buildings.

Asphalt Shingles

Shingle roofs with underlayment, ridge caps and ventilation.

Roof Coatings

Acrylic and silicone coatings for restoration and cool-roof performance.

Solar-Ready Roofs

Roofing coordinated with solar mounts and penetrations. See Solar Estimating Services.

Storm Damage and Re-Roofs

Tear-off, replacement and repair after wind and hail. See Xactimate Estimating Services.

In Depth

How We Estimate Roofing

Roof area and pitch

Each roof plane is measured in plan and adjusted for pitch to get true surface area. A 4/12 pitch adds about 5 percent to the plan area, and a 6/12 pitch adds about 12 percent. Areas are converted to squares (100 square feet).

Linear elements

Ridges, hips, valleys, rakes, eaves, walls and transitions are measured in linear feet because they require trim pieces, flashings and extra labor.

Penetrations and details

Vents, pipes, skylights, curbs, drains, scuppers and equipment supports are counted from the roof plan and MEP drawings.

System components

Underlayment layers, battens, insulation, cover board, tapered insulation, membrane, coatings and fasteners are priced according to the specified system.

Tear-off and equipment

For re-roofs, we include tear-off, disposal, deck repairs and protection. Equipment such as roof hoists, conveyors and cranes is added where needed.

Expert Guide

Arizona Roofing Systems Compared

Concrete tile

Concrete tile is the most common roof on Arizona homes. The tile itself can last for decades, but the underlayment beneath it wears out from heat and UV over time and is often the reason for roof replacement. Tile is heavy, so roof framing must be designed for its weight.

Spray polyurethane foam

SPF is widely used on flat and low-slope roofs in Arizona. It insulates, seals around penetrations and sheds water when applied with proper slope. It needs periodic re-coating to protect the foam from UV.

Single-ply membranes

TPO and PVC are common on commercial and industrial buildings. White membranes reflect sunlight and help reduce cooling loads.

Metal and shingles

Standing-seam metal is popular on modern custom homes and in northern Arizona. Asphalt shingles are used on some homes, particularly in higher-elevation communities.

Arizona Factors

Arizona Roofing Cost Factors

Heat and UV Exposure

Roof surfaces get extremely hot, aging underlayment and coatings faster and limiting midday work.

Hail and Wind

Monsoon storms can break tile, puncture foam and lift membranes, driving repair and replacement work.

Underlayment Replacement

Many tile roofs need underlayment replacement with tile removed and reset.

Northern Arizona Snow Loads

Flagstaff and other high-elevation areas need roofs designed for snow and freeze-thaw.

Cool Roof Requirements

Reflective roofing and coatings are often specified to reduce cooling loads.

Solar Coordination

Detaching and resetting solar arrays is a common re-roofing scope.

FAQs

Roofing Estimating Services FAQs

How do you measure a roof?

We measure each roof plane from the roof plan, adjust for pitch to get true area, convert to squares, and measure ridges, hips, valleys, rakes and eaves in linear feet.

Do you estimate tile roof underlayment replacement?

Yes. We price tile removal and stacking, underlayment replacement, broken tile replacement and tile reset.

Do you estimate foam roofs?

Yes. SPF roofs are priced by area and thickness with coatings, along with tear-off or preparation and flashings.

Can you estimate roofing from aerial reports?

Yes. Aerial roof measurement reports can be used along with photos for re-roof and insurance estimates.

Do you include gutters and downspouts?

Yes, when part of your scope. Gutters, downspouts, scuppers and leaders are measured by length and count.

How long does a roofing estimate take?

Residential roofing estimates are typically delivered within 24 hours. Commercial roofs usually take 1 to 3 business days.
