Hi Everyone,
I've just purchased a new home with a mansard roof which is pretty ugly. I'm looking for an economical way of creating a gable roof over the top of the mansard roof without removing the old roofing. Can I build a new rafter system over the top of this one. At the same time, I will remove the side part(the mansard) and replace with siding. If this is feasible, how do I tie the new ridge board and rafters securely to the new roof.
