Standing seam roof valleys?

[Dave Buckley]

I'm looking at roofing a bit more in-depth than I have before and I'm currently working onna standing seam type metal roof.

 

I've been following the 3dats books as a guide to the different types of roofs as I have no architectural background.

 

However, After i've created the standing seam, i want to add ridge and valley caps.

 

The ridges are ok, but I'm struggling to get the valley caps looking as though they have been finished off correctly.

 

How do you guys normally go about this? Any special techniques. The 3DATS book just says, "do the same for the valleys as you did for the ridge." but it's not that simple.

 

I need to make sure the standing seams aren't overlapping and look like they have been finished off properly.

 

Can anybody guide me a little?

 

Here's what I have currently.

 

I was hoping I could use a sweep with custom profile and then somehow use that sweep to cut the standing seams back to its edge

A valley detail would usually have a u-shaped channel running underneath the standing seam, with the sheeting overhanging a little to allow rainwater to run-off into the channel. You could do this by either creating a box then booleaning the roofing out, or by selecting all the vertices along the edge and moving them up, with the edge constraint activated, to form the gap.

[Dave Buckley]

so if i create the valley using a sweep along the line representing where the valley would go, then select the vertices of the roof and move them back to the edges of the sweep with edge snaps on?

 

Thats kind of how I understood what you were saying

[Stephen Thomas]

More or less. I meant turn on the edge constraint under your edit poly modifier to allow you to move the vertices along the edge of the profile rather than using snaps though. And thinking about it, a v-shaped section is probably better for the valley.

[Dave Buckley]

ah right ok, so using what you've said I'm currently at this point.

 

I'm just trying to get it finished off properly. especially this lover part of the image at the corner/joint

That's looking about right. I'm not sure about the lower part, it really depends how your gutter is working. You can download typical details from Kalzip that might explain things better than I can http://www.kalzip.co.uk/kalzip/uk/technical/technical_drawings.aspx
