I am building a two story garage/storage area, and I am making brackets for the rake overhang to match the house.  Overhang is just 12 inches.  My question concerns mounting the brackets.  As I see it, there are two choices:

A)  Mount the brackets to the gable wall over the house wrap and side around them or

B)  Mount the brackets over the siding (Hardi-plank with 5″ exposure) after cutting a “saw tooth” pattern in the back of the brackets to accomodate the siding.

Any suggestions on the best technique?  I plan on bolting the brackets through studs in the wall with carriage bolts.
