The problem
Why roofing estimates eat your evenings
Measurement reports cost money every time
Paying for a report on every lead adds up fast, especially on jobs you do not win. Arez measures from satellite with no per-report fee.
Waste and accessories get guessed
Starter, ridge cap, drip edge, ice and water. Arez adds them with waste so the order and the quote match.
Storm season means volume
When the phone rings all day, the contractor who quotes first gets the job.
How Arez handles it
One sentence in, an itemized roofing estimate out
- Arez reads the job and tells you what it assumed: one layer tear-off; 10% waste on shingles; decking in good condition.
- It builds the estimate with your labor rate and your 20% markup. Labor is in hours, so it is easy to check.
- Change anything by saying it, then send it as a proposal the customer signs on their phone.
