uh oh! hurricane clips go on the INside?! ha! I just built my roof yesterday and put them on the outside. Sigh. Ah well, I'm sure it's fine because i'm NOT doing it again. Hey, I love your coop!! You did a really great job and it's just so cute! Great colors- the trim is really pretty too!!
About the rafter ties, from the instructions I found online from strong tie, it shows them placed on the outside and on the inside. So I don't think it really matters. If everyone put them on the outside... I might be the wrong one! Think the important part is that you make sure you don't substitute rafter ties for birds mouth cuts.
