Adding a shed roof to a pole barn wall???

[towbar]

Hi everyone, I have a pole barn with 14ft walls, and I'm needing to add a small shed for my air compressor. The shed walls will be just slightly taller than the air compressor (say 7ft). The pole barn has the standard 36" ribbed metal running vertically. My question is how to attach the shed roofing metal to the existing wall without having a huge gap between the existing barn wall and shed roof due to the height of the ribs?

I have thought about it long and hard and the only thing I can come up with is to cut a slot horizontally in the existing barn wall metal, making it the width of the add on shed, and insert flashing metal that's been broken to the angle of the roof, and allow that flashing to sit flush on the ribs of the shed roof??

Any better ideas? Surely someone else has concurred this dilemma with success?

Maybe there is a simple solution I'm unaware of?

Thanks in advance for any help you can lend!

You got it. Be sure to put a steep pitch on your shed roof as water will blow under the flashing that is sitting down on the shed roof. The metal fabricators do make a foam like insert that fills in the corrugated "holes" when doing this also.jmo

Sounds like a plan. Have you looked at the metal manufactures site and all the different trim parts and extrusions that they offer for building situations like this? I'm sure they have an answer.

yup, and make the flashing long enough. and it counts as a post

Thanks for the replies guys!!

Well, that was about the only idea I could come up with.....seems like I'm on the right track though.

Anyone have any other tips or techniques??

Thanks, -Towbar

I just notched my roof panel of my shed to fit the ribs in the shop wall, and sealesd it with silicone, its been 3 years and theres 2 feet of snow on it right now, no problem,
cant really see that in this pic but here is my compressor shed

notch the roof piece around the ribs on the wall, like the picture shows, or you can also slip a piece of flashing in behind the wall, to cover the roof piece.

Thanks everybody, I appreciate the info!

ABADWILLYS....that's exactly the type of compressor shed I have in mind! Looks nice!

Remove the building wall panels where the shed roof span isto be installed. Frame the shed and install the roof and L flashing on the roof against the barn. Cut the siding you removed to fit the shed roof with 1/2" clearance on the bottom at the shed roofline to cover the flashing. Cut the lower portions of the removed siding to fit the wall again and seal. Finish the shed. Done

Steroblan has it figured out how to do it correctly.

I was planning on doing it the same way as in the picture.

J channel is what you are looking for. If you snip it just right, you can use one continuous piece to go all around the four sides of the cut out. You then run a few screws through the metal sheeting, into the back side of the j channel, and finally into your sheeting board.

There are a lot of good suggestions given already, but before you start cutting metal do as rburke65 suggests and check into the many specialty pre-formed finish trim pieces and foam seal strips available from the steel siding manufacturer. This is their bread & butter and they've been down this road many times before!!
