We're still trying to figure out how to place the ridge cap on that barn roof. Thinking of putting a ladder spreader on a ladder section and hooking it over the roof in a way that the 10' cap can be slid under it. I told the guy it would be worth it to run 2x4 x12' straps across the back side, down about 3 feet, to get a foothold. They could be screwed right in to the existing metal roof screw holes if they were backed out first. Very tough pitch to work on. I learned to work with the guy after almost coming to fisticuffs with him last year
Sometime you have a fight with your friends or brothers I guess. He's a farmer, used to rigging things up economically.
You saw by my previous pics, even a metal roof can get peeled off by the wind. After the hell of Sandy, I got pretty good at weaving shingles. Only need two tools to do it right. Except for one roof I patched that had shingles glued down to themselves too well to loosen them. Those I cut the tabs and had to tar/glue in new tabs to make the patch look good. That roof was beat and was scheduled to be replaced by insurance. It seemed like all the standard roof nails were popping down through the old shingles; an example of why it's good practice to nail them down just tight enough, but not too tight. That's old school though, I guess everybody uses nail guns or staples these days. I like to have a caulk gun with tar caulk in it handy. With roof cement caulk tubes, no matter how hard I try to keep it off me, it always gets on me.
