Flat Roofs are fabricated essentially with joists spanning the area between two walls, covered by high quality sheet timber or other material. If timber is used a further, waterproof covering is required. The weight of these last two coverings, together with the width of the span, form the basis of the calculation for the size of joists needed.

It is therefore important, that before building your structure you have the desired building regulation approval.
