About roof replacement

A roof replacement strips the old roof to the deck, repairs any rotten wood, and installs new underlayment, flashing, vents and shingles. It is the biggest job most homeowners ever buy for their house, so the written scope matters as much as the price: what comes off, what goes on, and who hauls the old roof away. Get more than one quote for the same scope.

What to ask a contractor

  • Does the price include tearing off the old roof and replacing rotten decking?
  • Which underlayment, flashing and ventilation are in the quote?
  • How long will the work take, and who cleans up the nails?
  • What does the warranty cover: the shingles, the work, or both?
