Professional roofing contractors are licensed, insured, technically competent, experienced and knowledgeable.
The following checklist will help you make an informed decision:
1. The contractor should furnish a copy of their contractors license. Call the local building department to make sure the license is still active.
2. The contractor should furnish proof of liability insurance. The insurance certificate should be sent directly to you from the insurer. Do not accept a copy.
3. Ask the contractor for references.
4. Ask the contractor to give you addresses of projects where they have installed the product or material that interests you.
5. The contractor should supply you with a written proposal that clearly details the work to be performed, materials to be used, workmanship and material warranty information and the full cost of the job. Remember to include orally agreed upon 'extras' in the written contract for documentation if a problem arises.
6. Ask the contractor for a start and completion time for the project and make sure scheduling meets your needs. You don't want your job put on the back burner, especially if you have roof leaks.
7. It is not unreasonable for a contractor to require a down payment, but never issue full payment until your roofing project is completed.
8. The contractor should obtain the required roofing permits. Be leery of a contractor who asks you to obtain these permits.
