Thanks for the questions.

My customer decided on wood.

The cover will go over a 10' X 20' slab.

I will use 6 x 6 treated lumber beams and the cover will be attached to
the house which has vinyl siding.

Shingled roof.

He has a whole house generator that can be hooked up upon a power loss.

He once lost power for a week.

What does a generator have to do with what type of roof will be used for
the patio cover?
