I have extended my chalet style house to two tradition story house by getting rid of the dormant windows. the back of the house has completed now and ready for the roof. because I am still living in the house I want to cut the roof for the back and move to the back of the house and do the front.
house can I calculate the size of the wood that is needed for the roof, i.e the rafters
