The roof line is the one most homeowners forget to ask about: equipment warranties come from manufacturers, while the holes in your roof are the installer’s. Get that coverage in writing, in the contract, not in a brochure.

How You Can Pay

  • Cash purchase
  • Financing (residential financing page)

Whichever route you take, ask for the cash price and the financed price side by side. The gap between them is where dealer fees hide, and it is the first number our quote guide tells you to find.
