Area alone does not describe a roof
Capture measured roof area or squares, pitch, stories, layers to remove, valleys, hips and ridges, penetrations, decking condition, flashing, ventilation, access, disposal, and local code requirements.
A voice script you can use
“Estimate a 2,000 square foot asphalt shingle roof with ten percent waste. One layer tear-off, synthetic underlayment, new drip edge, ridge vent, and replacement pipe boots. Decking repairs are excluded and priced after inspection. Lump sum is 14,800 dollars.”
Worked example
2,000 SQ FT · 10% WASTE
22 SQUARES
Use the result to plan shingles, then verify bundle rounding, starter, ridge cap, underlayment, fasteners, flashing, and accessories.
