Steam, yeah, I know that double selvage stuff. I would have used it, but bear in mind I got into this when all the roofing places were closed for the holiday. Also, it takes more tar and twice as many rolls. They had the Grace Vycor type of underlayment at HD, but that's like $100 a roll. I would feel better with even that. I used a notched trowel to coat the selvage with an even layer of tar, I think that helped.
Amazing that with at least 6 layers the roof still found a way to leak. I guess rain water turns mountains into sand with enough time.
I just used 15lb tar paper, got that down Friday, then the next morning it was all bubbled up in places and I had to cut a few places to get it to lay flat again. I layed out the roll roofing and let it sit for a while in the remaining sun to relax. It will probably buckle itself when It gets hot next year.
I never heard of corrugated roofing in 4x8, you mean galvanized steel?
Smitty holy *censored* you gotta have a roofing party! You could serve Absynthe and use green roll roofing. You could say you went green.
I slept again today, WTF I'm too old to do consistent labor anymore?
Haven't heard from the landlady, talk about no good deed goes unpunished...
chris, they were out of 30lb, had to get er done. If it was my place, I would put prefab trusses all the way up and be done with it.
