Reinforced concrete flat roof construction.

Basic construction guide of reinforced concrete roof with construction mixer. The roof should incorporate insulation and usually a vapour control layer to protect from interstitial condensation. 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. If a concrete roof isn t properly supported it can collapse especially if subjected to additional stresses such as earthquakes and snow buildup.

Types of flat roof coverings flat roofs can be made of a number of materials of which lead is the longest lasting. The steel joists will provide a strong foundation for the flat concrete roofing. These pores are interconnected within the concrete. 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. 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.
