Question on R panel closure/trim

[RodinaRanč]

I'm extending the R panel roof of an existing (shorter walled) shop so that it connects to an existing (taller walled) shop, to roof in an uncovered skinning rack area between the 2 buildings. The small shop roof extension will meet the vertical wall of the taller shop.

Other than using corner trim on the edge of the last roof panel (to give a flat edge) & foam outside closure strips (to fill the spaces where the last roof panel/trim butts up to the vertical wall, is there a better way to connect the roof R panel to the vertical R panel of the taller shop?

For a weatherproof connection, you need to cut the vertical wall panel and slip flashing in that your new roof panel will be below. Probably not what you wanted to hear but that's what it will take to stop all water from encroaching the joint.

I hear ya & thought about that too...just not sure i want to cut into the vertical wall for a space to skin critters & park a tractor...if i were storing feed/hay, i would do it. I'm covering simply to get out of the sun/rain when skinning more than anything. The slab there has a drain in it as well

When you say extending, I picture you adding length to existing roof sheets. If that's the case, isn't water running down the sheets?

[RodinaRanč]

Just the opposite...adding width (adding add'l sheets to the RH side of existing sheets, not to the ends of existing sheets). Once the skinning rack roof is added the 2 shops will basically "butt" together.

Yes they have a transition piece for R panel...Let me see if I can find a pic...You can have it broke on whatever angle...You can put r panel side up against vertical wall and flat side on top of small roof part...You will still need enclosures on that part...Hang on a minute for pic...

What will be the distance from the roof line of the taller shop to the junction with the new roof? How much lower is the new roof going to be?

Perfect...thanks! I'm no roofing expert, but it's hard to imagine there isn't a vertical to "pitched" transition/flashing

You will have to caulk the top of the r panel piece to help keep from leaking....Hopefully I am understanding you correctly and this is what you're looking for...

Peak of roof on smaller 8' walled shop is 14'....peak on taller 14' walled shop is 26', both shops are "engineered" not kit built so they match the house nearby

Perfect, Thank you! Exactly what i was imagining but couldn't seem to find

You'll have to call around and ask if they have it...Not all steel places will have it.....


Mueller shows to have it...Rib-Die formed transition is what they are calling it...

Well believe it. Here's the problem. As your roof sheet slopes down your wall, the highs on your wall sheets will not be 1' on center, due to the "run" down your wall. The steeper the pitch, the longer the run between wall sheet highs. You can put rubber closure between your flat trim and wall panels, but it wouldn't be totally waterproof, but that doesn't sound like an issue. How are you going to support your additional roof sheets between the buildings?

That won't work. That's a high end roof to wall transition.
