Reinforced Concrete Flat Roof Construction

The steel joists will provide a strong foundation for the flat concrete roofing.

Reinforced concrete flat roof construction.

A concrete slab flat roof is normally made up of a structural layer of concrete finished with a smooth screed onto which a water proof layer such as a membrane is laid. Depending on the designed strength density and installation techniques the number of pores can vary. The blocks come in several sizes but this guide will assume you are using a 16 3 4 inch wide concrete slab. Step 3 placing the steel joists.

These pores are interconnected within the concrete. One of the most crucial step in building a flat concrete roof is to figure out the size of the concrete block you will need. Interior support beams can help but the construction works best when concrete walls floor and roof form a solid shell. Types of flat roof coverings flat roofs can be made of a number of materials of which lead is the longest lasting.

Other metals can be used and you will often find asphalt or bitumen coverings. If a concrete roof isn t properly supported it can collapse especially if subjected to additional stresses such as earthquakes and snow buildup. For this reason adding a concrete roof onto a wood framed house requires a great deal of structural adjustment. The roof should incorporate insulation and usually a vapour control layer to protect from interstitial condensation.
