Name the product, not just the category
“Architectural shingle” describes a category. Ask for the manufacturer, product line, color, and the compatible components proposed for the roof.
Look under the shingles
The deck, underlayment, flashing, roof edges, and penetrations all need a defined scope. Clarify how existing materials will be removed and concealed damage addressed.
Discuss ventilation as a system
Intake and exhaust arrangements need to suit the building. Adding vents without considering the existing assembly is not the same as a ventilation plan.
Compare the written installation scope
Fastening, applicable local requirements, cleanup, and warranty terms should be part of the discussion. A square-foot price does not explain these details on its own.
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.
