Contractor quotes rarely line up neatly. The lowest number is often not the lowest project.
1. Scope of work
Is the quote a tear-off or an overlay? A retrofit insert or full-frame window?
2. Materials
Quotes should specify brand, product line, quantity, warranty terms, and allowances vs. fixed pricing.
3. Permits and inspections
Permits are not optional for most major work.
4. Site protection and cleanup
Is dumpster rental and magnet sweep included for roof work?
5. Payment schedule
Never pay more than 10% upfront on a residential project.
6. Timeline and crew
Who is on the crew — employees or subs?
7. Insurance and licensing
Ask for general liability and workers' comp certificates.
