Large gap under ridge cap
I have installed Galvalume metal roof and apparently the ridge opening is too wide with a very heavy, windy rain. I only have about 1 1/2" inches of roofing under the edge of ridge cap. I don't recall what size ridge cap I used.

Are larger ridge caps available? If not, I was planning on putting an "L" shaped piece of metal under the roofing, with an edge sticking up towards the crest of the ridge cap, to keep rain from blowing into the ridge opening.

Any suggestions

Thanks

Most ridge caps are designed for use with a closure of some sort. A metal "L" is one type of closure. There are also foam closures available, as well as profiled closures which allow for venting too.

I strongly suggest going back to your metal roofing manufacturer for their recommendation.

I do not think that a larger ridge cap (at least not by itself) is the answer to your problems.
Thanks for the reply. I did talk to my vendor and he said he did have larger ridge caps. But I also don't think that would be the answer after thinking about it. The vendor told me about the foam strips I could put under the cap. I was not aware of that. Nor was the person I had put the roof on (not a professional roofer obviously).


I am going with the larger ridge caps because I think it would look better because what I have now does not lie well on the ridge. I am also going to try the foam strips and I think that will do it.

Thanks again.
