Thanks guys, I still try, but getting harder all the time. This is the last one with cedar shakes, too many ways for them to get back in, I used 7 tubes of silicone caulk, and still have found them going back in this morning. Cedar shakes are definitely the hard ones NO MORE.. The height is a problem also, but the guy called and I answered (I know you can't fix stupid) at least that is what Si says on Duck Dynasty...
