Use this roof calculator to estimate asphalt shingles, metal roofing, roof pitch, tear-off layers, decking repair, and installed labor before comparing contractor bids.
Enter roof size, material, pitch, complexity, and removal assumptions to estimate a planning range before requesting bids.
Use the same roof size, layers, access, and material assumptions across every quote so cheap bids do not hide missing scope.
For per-square shingle pricing, compare 3-tab, architectural, premium, tear-off, and decking allowances.

Budget planning
Use this as a quote review checklist after you calculate your range.
Asphalt shingles are lowest cost; metal, tile, and slate raise the range.
Pitch, height, access, tear-off, and decking repair drive labor.
Keep room for permits, underlayment upgrades, flashing, and damaged decking.
Cost drivers
The same project can price very differently depending on scope, material grade, local labor, access, and timing. Use these factors to understand why two quotes may not match.
| Factor | Lower-cost version | Higher-cost version |
|---|---|---|
| Roof size | Standard roof size or simple scope | Premium roof size, difficult access, or complex project requirements |
| Material type | Standard material type or simple scope | Premium material type, difficult access, or complex project requirements |
| Pitch | Standard pitch or simple scope | Premium pitch, difficult access, or complex project requirements |
| Complexity | Standard complexity or simple scope | Premium complexity, difficult access, or complex project requirements |
Budget control
These steps help reduce bid spread, avoid surprise charges, and keep the final invoice close to your calculator result.
Compare at least three quotes using the same measurements, material grade, and project scope.
Schedule during slower contractor seasons when possible, especially for non-urgent projects.
Separate must-have work from nice-to-have upgrades before requesting bids.
Ask whether buying materials yourself helps or hurts warranty and labor pricing.
Common project sizes
Write down exact measurements and project scope.
Save your calculator result and share the same scope with each contractor.
Ask whether permits, disposal, delivery, and prep work are included.
Compare at least 3 quotes using the same material grade and timeline.
Material Cost = Roof Area x Material Cost per Sq Ft Pitch Adjustment = Material Cost x Pitch Factor Total = Material + Labor + Removal
