Advice on Coop and Run Doors, Windows, and Braces

[saysfaa]

OK, design revised to 2x4 rafters, added the threatened overhang off the run end, fixed the length of the run itself. This is where we are now at.

Please Comment if you see anything that looks odd.

Will the ridge beam make a ridge vent difficult? And is it necessary for a small building like a coop?

I haven't noticed any issues because of not having one.

Also, a metal roof usually needs purlins. I realize this is a rafter plan so it may be intentional.

I didn't draft in the purlins because they just lay on top, and there was some discussion of plywood decking instead - based largely on price.

Due to the large amount of weather sheltered venting on the coop, and the plan to leave the triangle between coop and run open, we didn't think there was much benefit to a ridge vent, which moreover could be blocked by Ohio snows. and yes, a ridge beam does reduce the amount of air which can pass thru a ridge vent by about 1.5sq Inch per linear, or 18 sq inch per linear foot (about 1 sq ft per 8 linear feet) - but most ridge vents are limited by the metal roof profile, not the size of the gap in the decking

Both good comments!

I missed the discussion about possible plywood decking. Is that instead of metal roofing?

No, under the metal. and it was in mail, not a forum, so I'd be worried if you hadn't missed it!

Yes, the purlins would just make it harder to see the rest of the plan. - as long as people know they need to be added.

I didn't know much about metal roofing on plywood but had a faint memory of knowing someone who did it and needed to put the purlins (furring strips?) over the plywood.

So I did a bit of looking. The internet says (so it MUST be true, lol) that metal directly on plywood sheathing is problematic. I haven't seen enough about why it would be to tell if it would apply to this. Maybe if I look in the morning - I think much better in the morning.

Thanks for the comments @saysfaa ! I appreciate the help from everyone.

@U_Stormcrow - any reason the coop roof is higher than the run roof? Should we make it the same? The walls for the coop and run are even and the double top plate has it all tied in.

 

[saysfaa]

The coop roof is higher so its roof will cover the porch without having two slopes.

I think you will like the porch. It would be easier to build, easier to maintain, and probably look better to have them the same height. One way to do it is to make the run a bit wider so the whole roof is like the coop roof. Another way is to make all the walls/posts taller so you can have the whole roof be like the run except the part over the porch continue on the same angle until the porch is covered - you would need it taller to do that so you have enough height to walk on the porch without ducking.

It looks great to me. Well-suited to the needs of the flock and the location.

As @saysfaa says, its so we could keep identical roof slopes and still have a covered porch in front of the coop. If you would prefer, we could instead change the angle of the roof over the porch, like the picture you showed, with the constructed trusses.

Ah okay. That makes sense. Thank you.

No thanks! I believe you said it’s easier this way! I’m happy with it!
