Opinion on what type of roof for the Chicken Run

i have two covered runs.and dh used tin,we bought it at lowes.its shiny so will reflect the sun.it keeps the runs really dry and cooler on the chickens for summer.

First, don't worry about the grass. There will not be any left. They will eat it all, then scratch up the roots and eat those.

To keep those climbing things out, I'd suggest at kleast 2" x 4" welded wire. I'm not sure what you mean by screen, but you need something strong enough they can't rip it apart, especailly the raccoons. Domestic cats are not much of a threat to grown chickens, but they will sometuimes take chicks.

Other than cost, I cannot think of any downsides of a solid roof. You need to slope it so the rain runs off, otherwise any roof will leak. It will provide shade, which they will need in Florida. Rain and sunlight will still come in from the sides, but a roof can help a lot. A huge help in keeping it dry is to position the coop so rainwater does not run into it. Place it somewhere a little high so it will drain and use swales and berms to divert runoff.

Corrugated metal roofing (basic galvanized stuff) isn't too expensive, and pretty durable.  If used over a relatively small run, it will help provide shade for your birds and cut down on wet / mud / smells.  A larger run gets a lot harder to roof economically, although maybe you could just roof part of it, and using screening over top of the rest -- ??

 

The fiberglass / plastic corrugated roofing is even cheaper and easier to work with than the metal stuff, but may not hold up quite as well in the long run.  And it may not provide effective shade if translucent and you live in a hot & sunny area (in fact, may make it even hotter -- people often use the translucent stuff for greenhouses -- !!).

I use the plastic corrogated roofing.  The smoke color blocks some sun but lets enough through that they get enough and it keeps them nice and dry.  Make sure you do enough overhang so the runoff doesn't splash in and when the rain that angels in gets in less.

One nice benefit to a solid roof is being able to install a rain barrel to provide water for the chickens, as long as it's not shingles. We installed a metal roof on our coop that drains into a 55 gallon rain barrel. Makes it nice since the whole operation is about 100 yards from the house and we don't have to schlep water any distance.

My husband is in the process of building our outside area, it will be 12 x 20,  I am covering 12 x 14 of it with

Costly, yes, because I have to put plywood underneath it, but I figure it will last a good long while.

 

I'll post a pic as he progresses, just got the 'beams' up:)

We used metal roofing sheets. It is REALLY noisy when raining but I know it won't leak and they'll have a dry place to run. It survived the golf ball sized hail we had this past March 2nd with just dents. It's lightweight and easy to install, just be careful with the sharp edges!
