Start with a complete assessment
Roof size is only one part of the picture. Existing layers, deck condition, slopes, penetrations, access, and local requirements all shape a replacement project.
Specify the assembly
Ask for the roof covering, underlayment, flashing, ventilation, fasteners, and drainage details to be identified. Compare products and methods, not just generic material labels.
Clarify uncertain conditions
Some conditions may only become visible after removal. Discuss how decking or other additional work will be documented, priced, and approved.
Plan the finish
Confirm cleanup, material disposal, final review, and delivery of relevant documents. Ask for the written warranty terms that apply to the exact project.
Make it specific to your home.
This is general planning information, not a diagnosis, quotation, insurance determination, or promise of product performance. A property-specific assessment and written scope are the next steps.
