We have a 21 year old home with a typical FL barrel tile roof. Over the past few years we’ve had a number of leaks repaired and are starting to think about a replacement.
. One of the surprising aspects of the first estimate is the differential in roof sq. ft. vs. home total sq. ft. Apparently, the overhangs and roof shape / pitch add about 40% to the home total sq. ft. in our case. I expected a difference but was surprised at how much of a difference.
For anyone who has done this before, how did you get comfortable or self calculate the roof sq. ft.? Other than the obvious reference checks and getting multiple quotes, how did you get comfortable that the roofer you chose was competent?
