Four-step plan
Define the project before you compare prices.
Start with the finished result you want. Then identify hidden conditions and permit requirements before every contractor prices the same work.
- 01
Describe the finished project
Write down the size, rooms or surfaces involved, product level, work included, and work excluded.
Leave with one written project description - 02
Inspect what could change the price
Ask what can be checked now and what will stay unknown until work begins. Put each unknown in writing.
Turn unknowns into written questions - 03
Confirm permits and inspections
Tell the municipality the exact work planned. Ask which applications, drawings, fees, and inspections apply.
Record who applies, pays, and schedules - 04
Compare the same written work
Give every contractor the same description. Compare products, allowances, exclusions, payment stages, warranty, and cleanup - not just the total.
Resolve differences before choosing
Collect final inspection approvals, warranties, manuals, lien documents, and the completed punch list.

How involved do you want to be?
Choose the route that matches your role today. Both paths use the same budget, permit questions, and written scope, so you can change direction without starting over.
I plan to hire a contractor
Good fit when: you want one or more contractors to price and complete the installed project.
- Give every bidder the same written scope.
- Compare roof area and pitch assumptions, tear-off layers and disposal, decking allowance per sheet.
- Check exclusions, allowances, payments, warranties, and final records.
I may coordinate parts of the roof project
Good fit when: you want to organize decisions, products, bids, or permit calls before assigning the work.
Compare products and bids, but assign measurement, safety, repairs, ventilation, flashing, and installation before assuming savings.
Safety boundary: licensed professionals should handle measurement, fall protection, repairs, flashing, ventilation, and installation.
Build the permit call list →HomeScope provides planning information, not construction instructions, structural design, code approval, or a decision that work is safe for an owner to perform. Confirm the project-specific steps with qualified professionals and the local office that handles permits.
Troy · 2200 roof sq. ft.
Based on 2200 roof sq. ft. (22.0 roof squares before waste), a broad local planning adjustment, architectural asphalt, 1 tear-off layer, and 5 decking sheets.
Compare contractor bids →This is not a quote, appraisal, or promise of market pricing. It excludes some design, permit, engineering, financing, concealed-condition, premium-finish, and temporary-living costs. Obtain written local bids.
The starting range is calculated from roof area - not house floor area - then adjusted for the selected Michigan community, material, pitch/access, height, tear-off layers, a visible decking allowance, and added roof-detail scope. It does not measure your roof or diagnose existing conditions.
- Confirm measured roof squares with each bidder.
- Ask for a per-sheet decking price and written approval before overruns.
- Require named shingle or metal products, underlayment, ice protection, flashing, ventilation, disposal, permits, cleanup, and warranties.
Roof cost by material
Compare three systems on the same roof.
These live planning ranges hold your current roof area, community, pitch, height, tear-off, decking allowance, and detail scope constant. Only the roofing material changes.
Architectural asphalt
$15,919–$30,425The common starting point for a complete tear-off and replacement comparison.
Use this material in the calculator ↑Designer / premium asphalt
$20,243–$38,741Higher-design shingles with product-specific installation and warranty requirements.
Use this material in the calculator ↑Standing-seam metal
$27,502–$52,700A different roof system whose panels, clips, trim, penetrations, and installer experience must be specified.
Use this material in the calculator ↑This comparison applies HomeScope planning factors to the same current scenario; it is not a product quote, lifespan claim, or promise of savings. Compare complete written systems, qualified installers, details, warranties, and exclusions.
How the cost works
Start with quantity - then add the work a unit price misses.
The calculator is transparent arithmetic, not a market quote. It multiplies the measured planning quantity by the published base range and selected community adjustment. A written proposal must then define the real products, labor, conditions, allowances, exclusions, and approvals.
Confirm how the quantity was measured and what waste or inaccessible areas are included.
Per roof square foot, before the selected community adjustment.
A broad planning adjustment for Troy, not a contractor quote or observed local bid.
Material, pitch/access, height, and tear-off form the multiplier; decking sheets and added-detail work form the dollar allowance.
Then verify the complete project with written local bids and add a separate contingency appropriate to the known risks.
Use current product prices to test a material allowance.
A bundle price omits underlayment, flashing, ventilation, waste, delivery, tear-off, labor, and warranties. A trustworthy snapshot names the exact product or dimensions, retailer or manufacturer, observation date, location limits, and everything excluded. It should not silently replace an installed-cost range.
Worked examples
See what the range means for a defined project.
These examples use the current base range and the Troy 1.08 local planning adjustment. They are arithmetic examples - not observed bids - and keep cost-changing choices visible.
1,600 roof sq. ft.
$11,200–$21,600Simple one-story roof area.
2,200 roof sq. ft.
$15,400–$29,700Moderate roof area before pitch and repair adjustments.
3,200 roof sq. ft.
$22,500–$43,200More roof area, still before complexity adjustments.
Do not add these examples to a contractor's quote without checking what that quote already includes. Use measured quantities, a written product specification, and local bids for the actual decision.
Roof cost questions
Answers for a more complete estimate.
How much does a roof replacement cost in Michigan?
Use measured roof area, not floor area. The architectural-asphalt base is $6.50-$12.50 per roof square foot before the local factor and calculator choices. Pitch, access, tear-off, decking, flashing, ventilation, and products change bids.
How do I estimate the size of my roof?
Use a prior proposal, aerial report, or contractor measurement that covers pitch, waste, hips, valleys, dormers, and overhangs. One roofing square equals 100 square feet of roof surface.
What should a roof replacement quote include?
Require measured area, tear-off, disposal, decking price, named products, underlayment, ice protection, flashing, ventilation, permits, cleanup, warranties, payments, and exclusions. Give bidders the same scope.
Should I budget for roof decking replacement?
Yes. Hidden damage may appear after tear-off. Require the included allowance, per-sheet price, documentation, and approval process. The calculator keeps this allowance visible.

Budget drivers
What moves the final price.
Tear-off and disposal
Existing layers, weight, access, and disposal requirements affect labor and hauling.
Decking condition
Soft or damaged sheathing is often priced as a per-sheet allowance until the roof is opened.
Roof geometry
Steep slopes, valleys, dormers, chimneys, and multiple levels increase setup and detail work.
Roofing system
Shingle line, underlayment, ice protection, ventilation, flashing, and warranty level should be named.
Permit planning
A checklist before work begins.
- Confirm whether a roofing permit is required for the exact scope.
- Ask whether tear-off, decking, and final inspections are required.
- Confirm contractor registration or licensing documentation the municipality expects.
- Ask who schedules inspections and how approved work is documented.
- Keep product approvals, contract, change orders, and inspection records together.
Better bids
Questions for every contractor.
- How many existing layers are included in the tear-off price?
- What is the unit price for decking replacement?
- Which shingle, underlayment, ice barrier, flashing, and ventilation products are specified?
- How will attic ventilation be evaluated and corrected?
- What workmanship and manufacturer warranties apply, and who registers them?
- How will landscaping, gutters, siding, and the driveway be protected?

From estimate to evidence
How to use this roof replacement cost range without mistaking it for a quote.
The calculator is most useful when it turns an early number into better project questions. Keep the quantity, local context, written scope, and contractor responses connected as the plan becomes more specific.
Confirm the measuring unit
This page begins with roof sq. ft.. Verify the quantity from drawings, field measurements, a contractor takeoff, or another appropriate project record before relying on the arithmetic. Record what the number includes so each bidder starts from the same boundary.
Replace assumptions with scope
The range cannot identify products, preparation, repairs, access, temporary protection, finish standards, or concealed conditions. Convert each cost driver above into a written inclusion, allowance, unit price, alternate, or exclusion before comparing totals.
Find the local permit office
Michigan requirements depend on the exact address and proposed work. Confirm the office that handles permits, application path, drawings, trade permits, inspections, fees, contractor documents, and final records through its official source.
Compare the same requested result
A lower proposal can reflect a different product, less preparation, missing work, larger allowances, earlier payment, or weaker closeout terms. Give every bidder the same description and compare written differences before selecting a price.
