Need help with slope and angles? Any other suggestions

[luvzmybabz]

I am working to get some breeder pens done houses will be 4x4x4 in front need to know how much slope to give roof so that rain etc will drain away from pen. the run will be 4x8 and the house will sit on blocks so the pen will be a little shorter in front. I am also planning exterior nest and for one side of the house to be hinged for cleaning watering food etc. I can do these I plan on making about 5 or so so far I need to know the angle to put on the top 2x4 to get the best slope for drain off without losing to much head room. OK I can't explain it all that well here is a picture you will see what is missing. Any other suggestions please give them.

If your roof is strongly-framed and honest to gosh *flat (well, tilted of course, but I mean no sags or hollows or lumps) then even just 4-6" of slope over 4' should be ok. Personally I'd go more like 10" just to make sure, but that's just me.

The only real reason for higher pitch would be to resist snow load and encourage snow to slide off rather than piling up. Which depends on what if any snow your area gets.

p.s. you don't need to calculate angles. Once you decide on slope, lay the side wall lumber out on the ground (make sure you get the two bottom angles exactly 90 degrees!), then measure where front and back wall heights will be, lay out a piece of straight wood connectinng those two points, and just trace the angles from it onto the wall pieces to get your cutting lines.

p.p.s. make sure the roof overhangs the walls, esp. at the low edge, to keep runoff from creeping inside of that wall.

p.p.p.s. therefore if you will have doors on that 'shortest' side of the coop, make sure they will not jam on the roof overhang when you try to open them. With a shallow roof pitch you may be ok without any special measures but it depends how you're doing your framing so be aware of this and check as you go along.

hope this helps,

The rear of my pens are at 6' the front of the pens are 6'6". It has enough of a angle for rain run off and plenty of head room for me to walk around inside without bumping my head.

You don't need much. I usually end up with 10 degs is all. I like to work with a nice nominal number. Makes it easy to set up the miter saw.

Good luck.

OK, thanks I think I can do this may have to call my spare boyfriend over to help (my hubbie's joke, it's his friend) unless anyone has a hankering to come to OKlahoma and help out.

Who was the one that made the coop with th fold down front for cleaning I can't find it anywhere and wanted to show hubbie a picture. I think whoever it was was going to make some to sell also.
