01
Start with the relevant experience
Ask what kind of roof the contractor worked on and whether the job involved repairs, replacement, or new installation. Find out how long ago the work was completed. A recent project can demonstrate communication and organization, while an older one may reveal how the contractor handled follow-up needs. Ask permission before requesting photographs or visiting a private property.
02
Listen for specific examples
Useful questions include how unexpected conditions were explained, whether changes were documented, and whether completion photographs were provided. Ask how the site was protected and how service requests were handled afterward. A reference is one part of due diligence, not proof that every crew or project will be identical. Compare what you hear with the proposed scope and the people assigned to your job.
