While there are no definitive guidelines for identifying a good contractor from a bad one, you can use the estimates provided to learn a good deal about their practices. This information may be just the differentiation you need to separate the good from the bad. A good contractor’s estimate should include all of the following:
- Type, color & manufacturer of roofing material
- All materials to be included in the project (underlayment, protective membranes, etc.)
- Scope of work to be completed
- Plan for existing roof – removal or replacement
- Plan for flashing – reuse, new, type of material
- Ventilation work to be completed
- Identifies party responsible for repairing or replacing exterior landscaping or interior finishing damaged during roof work
- Specific installation method
- Targeted start & completion dates
- Payment methods accepted
- Warranty specifications
