What a complete roofing system includes
- Roof deck or structural substrate
- Underlayment or water-shedding layer
- Flashing at walls, valleys, edges, chimneys, and penetrations
- Ventilation components where applicable
- The finished roofing material and accessories
Questions to ask before installation
Ask the provider to identify the exact roofing system in writing, including product line, underlayment, flashing approach, ventilation, decking terms, cleanup, permits, and warranties.
New construction versus replacement
A new roof on new construction differs from a replacement because there may be no tear-off, but the same attention to roofing-system details and installation quality still matters.
Document the finished project
Keep the signed agreement, product information, warranty documents, invoices, permits, and any photographs or inspection records supplied after completion.
