I'm somewhat familiar with isntalling cedar shingle siding, however there's one or two aspects that I've never quite been able to get good clear information about.
#1 On my cedar shake/shingle house, the shingles just butt right up to the sides of such things as door trim/ window trim and corner boards. There are no flashings and there is no caulk. I understand that caulk is not practical in this application because cedars shakes expand/contract so much. But is there some flashing that should be used? I was told by a roofer/sider guy that its not necessary because there's tar paper behind the shingles? I'm wondering because I am about the re-side another house with shakes, and was hoping to find out if there is a flashing for these situations...and if so how is it used?
#2--If I am residing a house with shingles....should I put the trime around the windows and doors on first? Or should I wait and put them on over the shingls?
