Creating Roofing Estimates That Convert
A roofing estimate is your sales tool. It tells the homeowner that you have thoroughly assessed their roof, understand the scope of work, and can deliver quality results at a fair price. The most successful roofing companies treat the estimate as a educational document that helps homeowners understand what they are buying — not just a number on a page.
Essential Components of a Roofing Estimate
A thorough roofing estimate accounts for every phase of the project:
- Roof measurements — total square footage, number of squares, pitch, and complexity factors
- Tear-off scope — number of existing layers, estimated disposal weight, and dumpster requirements
- Decking condition — estimated number of sheets needing replacement based on visible damage and age indicators
- Material specifications — shingle type, underlayment, ice barrier zones, drip edge, and ventilation components
- Flashing requirements — chimneys, skylights, walls, valleys, and pipe penetrations
- Labor estimate — based on roof size, pitch, complexity, and access difficulty
- Contingency allowance — for hidden decking damage only discoverable during tear-off
- Permit and inspection fees — required in most jurisdictions for full roof replacements
Estimating Best Practices for Roofing Contractors
Use aerial measurement technology (EagleView, GAF QuickMeasure, or drone surveys) for accurate roof dimensions. Supplement with a physical inspection to assess the condition of the existing roof, decking, and attic ventilation. Accurate measurements prevent costly material shortages and protect your profit margin.
Include a per-sheet price for decking replacement in your estimate with a note that the actual quantity will be confirmed during tear-off. This prepares homeowners for the possibility of additional cost without locking you into a fixed price for unknown conditions. Transparency about this contingency actually builds trust rather than creating concern.
Present your estimate within 48 hours of the inspection — faster is better. Include photos from the inspection, a clear scope of work, and a realistic project timeline. Speed and professionalism at the estimate stage strongly predict which contractor wins the job.
