What is the layout order of starting three tab shingles rows?

try it, you'll like it.

No, I like doing things right.

And why would your way be better? Please explain your reasoning. Don't give me the line about it being on the shingle wrapper, because Owen Corning's instructions show "vertical racking" as the proper method, (Perhaps they are a bit more up on the way the vast majority of roofs are laid down in this country) In fact, they recommend against running shingles across and diagonally.

Well, I read those directions and it does say to NOT run the shingles across and diagonally up but there are no reasons given. Can anyone give me a reason why those shingles should not be run across?

That's the way I've always done them. Does anyone know why Owens Corning insists on NOT using this method with their Berkshire shingles?

Mike

I don't know, but if I was installing these shingles I'd follow the directions given. Shingles I've installed in the past recommended having the edges staggered diagonally up the roof. I can't for the life of me see how this is easier when you have to leave out the fastener on the end and then interleave every other shingle on the next column. I'd rather work horizontally and diagonally where I can fully nail every shingle as I go and just lay them down and not have to pick up the loose end of another shingle to slip a shingle underneath it.

I would guess it has something to do with the pattern of the shingles, but I've not seen Berkshire shingles up close so that is only a guess.

So, you think it has something to do with the cosmetic appearance of the shingles rather than it's intended purpose, which is to keep water from leaking through them?

Mike

That is my best guess. It would be interesting to see the reason from O-C though.

Matt, I'm not sure how else to say this. In my younger days, I did some roofs your way. Run em' accross and diagonally up. Then one day I did a roof with someone who showed my how to run em up the roof. It was like a revelation. This was obviously much faster, even if you have to pick up the corner of every other shingle. Never went back to the old way. Way outweighs the time it takes to scamper back and forth. Every single roofer I know runs em straight up the roof.

and

I don't doubt that. The roofers I know and the ones that installed my roof didn't do that. I also know a lot of plumbers who will notch 3" out of the bottom of the center third of a floor joist as well. That doesn't make it right.

Marson , your talking to a f****ng idiot, let it go !!!
