Well.... I have 2 10x10 dog kennels side by side for "runs". Here's my problem. I spend 2 days adding tarps to tops of runs to keep everyone drier. I used 2x4,s spanned across top for support, and then ziptied the tarp to the outside frames. Everything looked so nice, and I was so excited my girls would stay dry. (They always look like drowned rats after a rain). We have been drizzling rain off and on for days. Anyway... a good rain just went thru, and when I went out to tuck everyone in tonight, the "roof" has acquired "pools" of water in between supports! Is there anyway to solve this, without building a whole complicated structure? (I'm on my own here! Hubby has no interest in my feathered kids. I can cut and nail boards, thats about it!) Any thoughts?
