Look for a contractor who is properly licensed (where required), carries liability and workers' compensation insurance, has positive customer reviews, provides written estimates, and clearly explains the scope of work. A reputable contractor should also be willing to answer questions and provide references upon request.

Yes. Comparing estimates from several qualified contractors helps you understand differences in pricing, materials, warranties, and the proposed scope of work. Be sure you're comparing similar services—not just the total cost.

Ask about the materials being installed, project timeline, cleanup procedures, warranty coverage, payment schedule, insurance, and who will supervise the work. A detailed written contract helps set clear expectations for everyone involved.

A lower estimate may exclude important materials, ventilation upgrades, flashing replacement, or warranty coverage. Instead of focusing only on price, compare the quality of materials, workmanship, experience, and long-term value offered by each contractor.
