Known roof surface area
Use a measurement that covers the actual roof slopes. The pitch control still checks whether the selected material is suitable, but it does not multiply an already measured surface area.

Understand the example before changing the inputs
A useful budget starts with roof area, not the living area printed in a real estate listing. A two-story house, a garage and an addition can change how much roof there is to cover.
Keep the example if you do not know your measurements. If you have a known roof surface area, enter that directly. The calculator shows how area and material change a national installation budget, then explains the additional work a replacement estimate needs.
Explore a roof installation budget
Change the example below. The range covers basic installation under the stated national model; removal, damaged decking and project-specific charges need a separate allowance.
Keep the 2,000 sq. ft. example, or enter an area you already know. Roof footprint means the area covered, not total living space.
Keep the 6:12 example unless you already know the pitch. Pitch helps check material suitability.
Planning budget example
Planning example for 2,000 sq. ft. of actual roof surface, using asphalt shingles. Removal and damaged decking need a property-specific allowance.
Basic installation under favorable site conditions. The whole replacement price also depends on removal, roof details, access and concealed damage.
Discuss your roof projectNational basic installation planning example. Roof removal, damaged decking, fees and tax need a separate property-specific allowance.

Sources and what the installation example includes
Asphalt installation uses Homewyse’s September 2026 national range of $5.21–$6.82 per sq. ft.; standing-seam metal uses its May 2026 range of $17.74–$23.95. These are basic midrange installation models for favorable site conditions, not a Farmington price survey.
The example includes the model’s basic labor, materials and listed installation supplies. Old-roof removal is an optional source item and is excluded here. Damaged deck or framing, permit/inspection fees, material sales tax, general-contractor supervision and unlisted work are excluded. Complex roof details and access need their own price.
Known surface area is used directly. A footprint is multiplied by a simplified pitch factor; the example does not measure overhangs, multiple pitches or project-specific waste. A roofing square is 100 sq. ft.
What the roof-area input tells you
The input basis changes the surface used in the calculation.
Roof footprint example
A footprint is the horizontal area the roof covers. The pitch adds slope length to that footprint in this simplified example. Multiple roof pitches, overhangs and waste need a project measurement; total living area is not a substitute.
From a planning range to a replacement estimate
A full replacement estimate also needs the old roofing layers, deck condition, flashing, drainage and access checked. The calculator does not inspect those parts or add an invented allowance for them.
Discuss the chosen material and the parts of the project with a roofer. A useful proposal sets out the included removal and disposal, the new assembly and how additional concealed damage will be approved.
The roofing cost guide explains those scope changes; the replacement service develops how the roof work is carried out.

Roof cost calculator FAQs
Are these Farmington installation prices?
The figures are national Homewyse installation examples, with the source dates and assumptions shown beside the tool. A Farmington estimate depends on the measured roof and the actual work.
Can I use my home’s living area?
Use the example unless you already know a useful roof measurement. Living area can include more than one floor and leave out garages or covered porches, so it can misstate roof size.
Why does the tool reject shingles below 2:12 pitch?
Asphalt shingles require a suitable roof slope and installation. A lower-slope roof needs a different system; discuss that section with a roofer rather than using a shingle budget.
Does the result include tearing off the old roof?
No. This installation model excludes removal and damaged decking, along with project-specific charges described in the method note. The replacement proposal needs those items priced.
