Roofing Contractor Interview & Quote Checklist

A lower number is not a lower price when the scope omits decking, flashing, ventilation, disposal, permits, protection, or closeout. Use this page to make every bidder price the same roof system.

Contractor interview

Eight conversations before you compare price.

01

Measured scope

What measured roof area, pitch, access, stories, and existing layers does this price assume?

02

Exact system

Name the covering, starter, underlayment, ice protection, flashing, ventilation, fasteners, and ridge/edge components.

03

Decking

What decking condition is included, what is the per-sheet replacement price, and who approves an overage?

04

Water details

How will valleys, sidewalls, chimneys, skylights, penetrations, and kick-out flashing be handled?

05

Ventilation

Who evaluates intake and exhaust ventilation, and what calculation or manufacturer requirement supports the plan?

06

Permit and inspections

Who confirms the enforcing agency, applies, pays, schedules inspections, corrects issues, and delivers final approval?

07

Protection and cleanup

How are landscaping, siding, gutters, windows, driveway, attic, and magnetic nail cleanup protected and documented?

08

Warranty and closeout

What workmanship and manufacturer coverage applies, who registers it, and what records do I receive before final payment?

Whole-system comparison

A roof is more than the visible shingle.

Project sequence

Plan milestones—not promised calendar days.

1

Measure and diagnose

Confirm roof area, slopes, layers, access, visible damage, attic ventilation, penetrations, and special details.

2

Normalize bids

Issue one written scope, compare exact systems, verify credentials, references, insurance, warranty terms, and exclusions.

3

Confirm permit path and products

Resolve the enforcing agency, application or inspection steps, material availability, colors, dumpster and delivery placement.

4

Tear off, inspect, and approve changes

Document concealed conditions. Require written quantity and price approval before decking or structural overages proceed.

5

Install the complete system

Coordinate water protection, covering, flashing, ventilation, edges, penetrations, and weather protection.

6

Inspect and close out

Complete required inspections, cleanup, attic and exterior review, punch list, warranties, photos, receipts, and final records.

Weather, inspection availability, concealed damage, product availability, roof complexity, crew size, and change orders can alter elapsed time. Obtain a written sequencing and communication plan instead of relying on a universal duration.
