Slopeless Roof?

[Zahboo]

I am planning a 40x8 pen/coop. It will have a back and 2 sides, the front being open. I am unsure if I'm going to make it divided for bantams and standards, but IDK. Is it okay for the roof to be flat? I was going to do Corrugated metal, 2.5x9 for 9 dollars

I love the price hehe.

How big of a problem is a slopeless roof The 1 foot overhang will help keep rain out of coop. The sides will be OSB plywood painted with exterior paint. Fence is Chainlink that will have chick wire over bottom 3 feet

Heavy rain, freak snow, flat could be flattened

would a small slope be okay? just a few inches? we get maybe 5 inches total snow a year, and there is thunder storms, but nothing too bad usually. I guess I should make it a little sloped to run off wind though ....

I would suggest around a 2-12 pitch....the more the better of course, but not enough will hold leaves and such which in return will cause the tin to rust and leak that will lead to rotting wood.

I will probably have it 4inches at the front then, just enough for a slope. I don't want too much. I'll play with angles.

You will not be happy with the results of a 4" drop over an 8' span. That is much too close to flat. Water and trash will accumulate, hatch mosquitos, and ruin the roofing. I would not do less than 18" over 8', and that is not a lot.

Remember that all flat roofs will leak. They still make buildings with flat roofs and they either have a rubber membrane covered with loads of tar an gravel or just the rubber membrane. They all will leak. Heck th building I work in now is a $100 million dollar building with a flat roof. Only been standing 10 years and leaks like a bucket with no bottom. You should really consider a greater pitch. Most flat roof buildings use a .25/12 pitch to allow for drainge but it will still leak. You are gonna regret the flat roof within a few years or so. My advice is go more then 2/12. 3/12 or 4/12 would be better.

Exactly precisely what Jeremy said, emphasis on "the you SO gonna regret it" concept.

It is not hard AT ALL to put a bit of pitch to the roof.

Flat metal roofs can be done, but the roofing is heavy corrugated steal with large overlaps. The frames for the roofs look like bridge trusses. This is what is commonly found in strip malls. There is a pitch, I don't remember what it is, but most have leaks that show up eventually. IMHO I would avoid a flat roof.

I would put a slop. Even it small, it will help keep water from sitting on the roof since puddling is going to happen on a flat roof. It will save you time and money later on.
