Homeowner roof guide

What changes the cost of a replacement roof?

Roof size matters, but material, stories, roof shape, removal, repairs, access, and local pricing all affect the final project.

Quick answerStart with measured roof surface—not just indoor living area—then compare materials and account for the actual installation conditions.

Start with the roof, not the living area

Garages, porches, overhangs, slope, and multiple roof sections can all change the surface that needs material. One roofing square equals 100 square feet of roof surface.

The address calculator measures the property first, then shows the roof squares used in the planning range.

Material is the biggest visible choice

Architectural shingles are a common baseline. Premium shingles, standing-seam metal, and tile carry different material, accessory, labor, handling, and structural considerations.

  • Architectural and premium shingles
  • Standing-seam metal
  • Tile where appropriate
  • Complete accessory, flashing, ventilation, and warranty system

What an onsite visit still verifies

Imagery and records cannot confirm every condition. A final proposal should verify the deck, tear-off layers, access, flashing, ventilation, permits, protection, disposal, exact products, and written scope.

Frequently asked questions

What is a roofing square?

A roofing square is 100 square feet of roof surface. The material order also includes a project-specific waste allowance.

Why is an instant estimate a range?

Decking, tear-off, access, flashing, ventilation, permits, and final products still require onsite verification.

Can an address estimate replace a roof inspection?

No. It is useful for planning and comparison, while the final scope requires an onsite inspection.
