How do I cut the pre-formed metal ridge caps to join them without leaking? (New Midwest Mfg. Pro-rib roofing, 5/12) Thanks	Guest User 3/26/2009	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/13021/find/
I am not familiar with that company. Can they not provide instructions?	Todd Miller Isaiah Industries, Inc. 3/28/2009	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/13022/find/
It's a generic question - how do you cut in order to join any inverted V-shaped pieces of sheet metal together at the point where the ridges meet? Thanks p.s. Midwest supplies the metal roofs for Menards.	Guest User 3/29/2009	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/13023/find/
Del, I hate to disagree but I do not see this as a generic question. Some ridge caps need to be trimmed in order to telescope together. Additionally, the exact detail of how things are handled beneath the cap can make a difference. And in any event it is important to adhere to manufacturer instructions so that the system performs as intended. Based upon your description though I assume the ridge is a through-fastened product and it is just a simple V shape. Most manufacturers would say to overlap the pieces at least 6" and seal in between the two pieces. If the lap falls over the rib, screw the pieces down as normal. I hope this helps. I am not trying to be difficult but every system and manufacturer can be different. As a general rule, if a manufacturer cannot provide detailed instructions on such things, it may be an indicator that you're working with the wrong manufacturer.

I've got the same issue - TWO ridges at equal height intersecting at 90 degrees (from your answer, it didn't sound like you heard the original question correctly). One is the main ridge of the house, the other is a gable dormer. There must be a best practice for assembling the intersection, but I haven't been able to find it. I'm at the point of squashing the dormer ridge and cutting a v out of the main ridge to saddle over it. Not very pretty... Any advice?

to deranger, basically that is the way you do it. You don't just squash the dormer ridge, you make it form to the valley and turn up under the main ridge. Sometimes you have to slit the middle of the ridge for an inch or two and sometimes you don't. The main ridge will have to have a "V" cut out of it to fit the dormer ridge and you will have to use some sealant where the center of the two ridges meet. Where the "V" is cut out, you will have your dormer ridge under it, nothing to worry about there. This can be done tidily and neatly if you use some seamers and make neat, clean folds in your dormer ridge.

Thanks, Wade. You made it sound much nicer than the way I said it... ;-) PS Really - thanks!	Guest User 7/26/2009	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/13027/find/
