Three quick questions

Only used to confirm Ohio or Michigan.

How big is it?

A rough estimate: we assume a 6/12 pitch and 10% for overhangs. Change the pitch under "Refine" below.

About the budget range

Roof prices depend on condition, materials, pitch, access and what's under the old roof. For early budgeting, the planner multiplies your roof area by our planning setting for the material you choose: $500–$1,000 per square for architectural shingles; $1,000–$1,800 per square for standing-seam metal; $500–$1,200 per square for exposed-fastener metal; $500–$1,000 per square for flat or low-slope roofs (EPDM or TPO) (a square is 100 sq ft of roof surface). We set this range for budgeting. It is not a verified Ohio or Michigan market average, it is not based on observed local job prices, and it is not a contractor quote.

The base range assumes one layer torn off, architectural shingles, standard underlayment, flashing and cleanup. It excludes deck replacement, major ventilation changes, difficult access, special materials, gutters and structural work. Those can change the price substantially.

We do not show dollar figures for metal, other shingle types, low-slope roofs, repairs, coatings or commercial roofs. Read the methodology.

How to use this tool

  1. Enter your ZIP code so we know whether Ohio or Michigan settings apply.
  2. Give the size the easiest way you can: house size, a measured area or the footprint.
  3. Pick the shingle type, then open “Refine” if you know the layers, pitch or damage.
  4. Use the scope list and contractor questions to compare proposals line by line.

Replacing a roof in northwest Ohio and southeast Michigan

Most replacements here happen from spring through late fall. Winter work is possible but slower, and shingles may not seal down until warm weather. Many cities in the Toledo and metro Detroit areas require a permit for a re-roof, and some require a mid-job inspection of the deck or ice barrier.

Michigan requires a state license for residential roofing contractors. Ohio has no statewide residential roofing license, but many cities require contractor registration. Ask every bidder which applies to your address.

Roof materials compared

MaterialBest fitWinter performanceTrade-offs
Architectural shinglesMost pitched roofs 4/12 and steeperProven with ice barrier at eaves and good attic ventilationWind and ice dams are the usual failure points
Standing-seam metalLong-term owners, low-maintenance goalsSheds snow well; needs snow guards over doors and walkwaysHigher first cost; specialized installers
Exposed-fastener metalBarns, garages, outbuildings, some homesSheds snow; screws need periodic checkingFastener washers age and can leak
Low-slope membrane (EPDM or TPO)Flat and nearly flat sections, porches, additionsPonding water that freezes is the main riskDrainage and seam quality decide the life

Each material uses its own provisional planning setting in this tool. Final price depends on condition, layers, deck and access.

Frequently asked questions

Where do the price ranges come from?

They are our provisional planning settings, set after reading published 2026 cost guides: $500–$1,000 per square for architectural shingles; $1,000–$1,800 per square for standing-seam metal; $500–$1,200 per square for exposed-fastener metal; $500–$1,000 per square for flat or low-slope roofs (EPDM or TPO). A square is 100 sq ft of roof. They are not a verified Ohio or Michigan average and not a contractor quote.

Why is there no price for metal or other materials?

We only show a dollar range where we have set one on purpose and labeled it. For metal, 3-tab, premium shingles and low-slope roofs we have no reviewed figure, so the planner builds your scope and points you to a quote.

What can make my price higher than the range?

Deck replacement, extra layers to remove, steep pitch, three or more stories, complex roof lines, chimney or skylight flashing work, ventilation changes and gutters are all outside the base range.

Can new shingles go over my old roof?

Sometimes, but model codes generally do not allow it over two or more existing layers or over wet or deteriorated roofing. Your local building department decides, and most proposals for older homes call for a full tear-off.

Do I need to give my contact details to see the plan?

No. The full scope summary and budget information appear first. The request form is optional.
