New roof for "New" garage.

This "New" Garage was built in about 1978 at a cost of about $4k.  "New" because it supplemented an older garage circa 1940.  Roof was poorly done and leaked at the juncture of the two slopes.  Now, it needs a new roof and the rotting wood replaced.  Cost?  ~$10k.  The new roof may be a candidate for a PV install.  The building has become of increasing interest to me because it is the electric connection point for all the new PV I've been installing.
