House is around 3100 sq ft and is 2 stories. I am going to guess there is a little over 1800 sq feet roof because garage area (one with 1.6 kW) in top left is not included in sq footage. But I am not a home guy so it is a guess.
Assuming you have a System Price Sheet, the first Solar Roof lineitem should give the number of estimated square feet for your roof.
