Ridge cap question

[Solidoak]

Should I be concerned about snow backing under the ridge cap on a 7/12 pitch roof? I know they sell those foam sealants but I never used it and am wondering if having nothing under the ridge cap will cause potential problems..?

I assume you're talking about a metal roof, in which case yes I'd definitely seal the openings. There's been several threads where people have had much better and way cheaper solutions. If you don't seal it you'll get windblown rain and snow up there, also insects, birds and small critters. The best solution I've seen was a piece of angle positioned at the top of the roofing so it blocked the channels. The leg of the angle was the same height as the corrugations on the roofing. You can also do the expanding foam thing, but that can turn into a mess.

If you're talking 3-tab or architectural shingles, you should have nothing to worry about. If you have ridge venting, they have built in baffling so again, nothing to worry about.

Yes, it is a metal roof.

I just don't see how snow is able to backup inside there on a 7/12 pitch?? I also installed a wire mesh inside to prevent any critters from getting inside the shop. Are there a any simple push-in foam blocks since I've already done put the ridge cap on?

Do you have links to those threads or the thread title so I can search it? I've already capped 85% of my roof so installing angle iron is proabaly out of the question. Not to mention, a 7/12 pitch doesn't allow easy walking up there...

Mine came with a shaped foam strip,check with your roofing supplier.

Here's the thread.
Snow will blow in if the wind is right, doesn't matter what the pitch is. What's inside the building? If it's just tractors and horses it's not such a big deal.

Mine is a 4/12 pitch and we had a very small amount of snow blow in last winter, not really enough to worry about. Like Beez said, if there's nothing critical in there don't sweat it. We lost a couple bales of hay at the most.

Thanks for the link, this answers my question. I'll have more than just equipment in there so closing the ridge cap is crucial at this point.

I use a building for my equipment storage and shop that has a metal roof and about a 6 or 7 12 pitch. not only will snow blow under the ridge cap but rain will as well. It is a mess.
