Yes, they will definitely be easier to clean. As long as the roost is flat, they should be fine.

I agree with one of the previous posters, I wouldn't use anything cloth, fabric, or carpet-like in my coop. Especially on the roosts as they will get pooped on the most. It will become reeaaally smelly and really dirty very quickly. The fabric will hold in the bacteria and the smell and you might never get it out. I don't think there would be anything wrong with having bare wood for a roost. I have only ever seen that used.
