Standard Homeowner Vetting Rules
Never execute written contracts based purely on the lowest price bid. Low bids are often the result of lacking General Liability insurance or using sub-component installers with minimal experience. To understand safe, standard averages, consult our new roof cost manual.
- Verify Active Licenses: Confirm licenses directly via state regulatory boards (e.g. California CSLB).
- Demand written Lien Waivers: Avoid getting locked into double-pay issues with material suppliers.
- Refuse 100% upfront pay requests: Limit upfront deposits to 10% or $1,000 (standard state capping guides).
