UI am attaching some cedar shingles to an old railway station (from half way up the wall to the roof line). I have been using 16 gauge 1&1/4" galvanized staples, I think I should switch to stainless steel or aluminium. Any suggestions? There is an 8 ft. overhang on the sides and 40 ft overhang at each end so the siding isn't totally esposed.
Part two is where do I look for a supplier? The Home Depots don't carry and weren't much help.
