Project Inputs
Adjust the job details, then tune your pricing assumptions if needed.
Example: 28 squares = 2,800 sqft of roof area.
Estimator Logic
Material and labor rates change by roof type. Pitch increases labor intensity and adds a small
waste factor. Tear-off layers drive disposal and cleanup costs.
Use Case
This is a contractor-style base estimate. Add taxes, permit fees, overhead, and profit margin
separately if you want a final bid number.
Pricing Controls
Roof-type base rates auto-load when you switch systems. Override them if your market is different.
Detailed Breakdown
Every major line item rolls into labor, materials, disposal, and the total base estimate.

Assumptions

Calculation Notes
- Roof coverage is priced in squares. The tool never asks for raw sqft as the primary roofing unit.
- Pitch increases labor and waste because steeper systems install slower and cut more material.
- Tear-off layers add disposal per square per layer, plus a haul base whenever disposal is needed.
- Flashing, valleys, vents, and gutters are priced as combined scope add-ons to keep the total practical.
What To Add Separately
- Permits and inspection fees
- Taxes and supplier delivery surcharges
- Overhead and target profit margin
- Decking replacement, skylights, and specialty trim
