If you take a look at this picture:
Which means I will have to find another way to route wires and ducts on top. The roof has very little room a few inches with insulation that's all. The second story on the left side actually has an exterior door where it opens and one can walk on top of the flat roof.
What I am wondering is how easy will it be to build a new flat roof on top of the existing flat roof (but elevated 24" or so higher) so we can use that room to route wires and ducts. Then I can cover the roof with flooring material (tiles or slates?) and put railings around it's perimeter so the roof becomes a sun deck.
Will this be a prohibitively expensive project to do? How would I determine if I can put new flooring on the roof - whether it was designed to take this added weight or for someone to walk on? Any other ideas?
I know this is probably more a question for a contractor, but this is a house I plan on putting an offer on and I need to get as much information as possible about what can and cannot be done.
Thanks in advance,
MC
