Just a thought, I have one of these prefab coops also. The first thing I did before introducing chickens to it was apply Thompsons water seal to the entire coop. I also got some silicone roof sealer and sprayed all of the cheap composite sheeting that was on it. Last but not least, I went back over and silicone caulked every gap I seen. This should help with making your coop last a little longer.
