Roofing "expert" couldn't find the hooked blade utility knife to cut shingles with... and the tool "expert" did not know what a manual impact driver was. LOL
I too did drip edges all around, but I have a shed roof. For ventilation I left a gap between the roof and the siding all the way around the entire coop. That gap is probably 2-3 inches tall all the way around the structure. We have average summer days around 70F and winter average nights of around 35F.... so mild year round and I'd venture to say that I could probably go with even more ventilation with just 8 birds inside a 6x8 structure all night. However, I am used to birds living in tractors where a tarp was their roof. Gable end vents might be a good idea just becuase chickens give off lots of humidity.
