SAMPLE OVERVIEW

A structured breakdown of roofing scope, systems, and pricing.

Roofing estimating requires coordination between roof plans, sections, details, elevations, specifications, manufacturer requirements, drainage layouts, penetrations, and edge conditions.

Our estimates are organized so contractors can review roof areas, insulation build-ups, membrane quantities, flashings, accessories, labor requirements, measured quantities, and pricing assumptions before bid submission.

HOW WE WORK

From roof plans and details to a bid-ready roofing estimate.

Each estimate follows a consistent workflow designed to improve scope coverage, system accuracy, quantity clarity, and pricing reliability.

01

Document review

Roof plans, architectural details, sections, elevations, specifications, addenda, schedules, and bid instructions are reviewed together.

02

System classification

Work is separated by roof type, membrane system, insulation thickness, substrate, slope, flashing condition, edge detail, and accessory type.

03

Quantity takeoff

Roof areas, insulation, membranes, cover boards, flashings, copings, curbs, penetrations, accessories, and fasteners are measured and organized.

04

Cost development

Labor production, wage rates, material pricing, waste, equipment, access, hoisting, installation conditions, and project requirements are incorporated.

05

Quality review

Roof areas, system assignments, flashings, penetrations, waste, assumptions, formulas, and summary totals are checked before delivery.
