Getting ready to put the roof on my new 12 by 16 sugar house. My question is about the cupola build. I see some that look like they are just dropped onto the roof with the rafters still in place, and some that appear to be built into the roof. Is one way right ? I feel like it should be built on shortened rafters with a framed sill , like a mini house. Also my evaporator pan is 2 foot by 4. with a 3 by 2 syrup pan. So I planned to make a 3 by 4 copula with drop down doors. Does that sound right. Oh and if your have any framing pics I would love to see them

Thanks
