Planning to attach a bb backboard to the eave of a garage. 2×8 fir rafters (~4/12 slope) on 24″ centers running perpendicular to backboard face. This will require two (1/4″x2″ steel flat bar) brackets (for 2×4 diagonal braces) lag-bolted through the comp shingles and 1/2″ plywood sheathing into the top surface of two rafters. Any thoughts on the following concerns/questions is appreciated:
1. Brackets placed directly onto existing shingles? – OR –
2. Cut away shingles for direct bracket contact with plywood sheating?
3. If method 1 is used, best method for permanent (weathertight) seal (e.g. silicone under and in penetration)?
4. If method 2 is used, same question as Q3?

Rather than answer your question I would ask why you would want to mount a hoop to the side of your building and let it incure all the pounding and possible damage, not to mention all the strain from dunks and hanging from the hoop as well as the limited room under the basket? I put a pole to the side of the drive and kept the teenagers away from the house. Of course, I destroyed my fathers garage door with our roof mounted backboard over it back in the day when the now available backboards were not around.
Thanks for your feedback, but the dunking, etc. will be minimal. That side of the garage is where a relatively flat area exists to serve as the court and there's also a generous overhang of the eave. So, that's the logical place for backboard to be installed.
