I am thinking of building a porch (approx 18ft x 7ft), I would like to put a flat concrete roof on it, with a view to also use it for a balcony. How do you manage to get a waterproof seal where the roof joins the house, and is it advisable to have a very slight 'fall' on the roof so the water runs of it? Do you have steel reinforcing mesh in the concrete, and how thick would the roof have to be. I would obviously use a architect to do plans, permission etc. Just interested in the views of the members of the forum before I contact an architect.
