Frequently asked questions+
Does this price rafters or trusses?
No. Roof structure is excluded.
Is the roof area exact?
No. It is a physical-area proxy; future project data can replace the proxy.
Are windows priced only by square footage?
No. Windows use package rates based on count, frame, and level.
Is this a contractor quote?
No. It is a planning budget, not a commercial quote.
This is not a construction estimate or contractor quote. Confirm scope, dimensions, and installation conditions before ordering.
