Looking for some advice on building a lean-to porch roof (1 metre wide by 0.7 metres deep), cantilevered off the house using 4x2. In terms of keeping the elements out, is this right for how to layer the roof?:
1. Plywood or shiplap cladding onto the joists
2. Felt
3. Battens
4. Concrete tiles
5. Lead flashing at 'ridge' where the roof meets the house wall (this will be inserted inbetween the mortar).
Is the plywood/shiplap necessary? If so, which is best? (there will not be a plasterboard ceiling inside the porch)
