Sotto - On your large one what did you do for the top edge of the roof to prevent water from going under the shingles? I don't see any caps up there just what appears to be the start of shingles.
Did you just put tar under that last row and call it good or what ?
I have a similar structure and that is what I`m trying to figure out now.
Also, how come you did not do any eves?
More pictures of that inside/out during construction would be awesome if you have them... maybe a new POST or PM me ??
