I'm hoping someone with roofing experience or know how can offer me some suggestions on what might work to weatherproof the roof of my round bin coop. I'm looking for something cost effective (hah) that will last a few years or more. I plan to put metal on eventually, just not in the already blown budget this year. The roof is 2 layers of old, weathered plywood and amazingly doesn't leak - yet. I don't want to get to the yet part. DH wants to paint it with tar, but there must be a better option...any ideas? Thank you.
