Roofing & Gutter Calculators
Estimate roofing and gutter costs before you ask contractors for quotes.
Roof and gutter work is one of the larger outside expenses a homeowner faces, and quotes can vary a lot from one contractor to the next. Knowing a realistic range for your home makes it easier to spot a quote that is far too high, or one that is so low that something important has been left out.
The calculators in this section estimate roof area from your house footprint and pitch, then apply 2026 installed price ranges for each material. The gutter calculator adds downspouts, guards and removal of the old system. Every cost page lists its sources and the date the prices were last reviewed. These are planning estimates, not quotes, so always get written prices from licensed local contractors.
Before you hire a roofer or gutter installer
- Get at least three written quotes that list the same materials, so you can compare them fairly.
- Ask what is included: tear-off, underlayment, flashing, downspouts, cleanup and permits.
- Check licensing and insurance requirements with your state or local building department.
