Metal Roof On Concrete Block

Concrete block reinforced masonry tilt up concrete load bearing walls may be combined with some heavy steel framing.

Metal roof on concrete block.

U value has an inverse relationship to r value. For example a building with material with an r value of r 11 converts to an u value of 0 09 1 r or 1 11 0 09. 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.

The blocks come in several sizes but this guide will assume you are using a 16 3 4 inch wide concrete slab. Floors commonly concrete on steel deck for multi story buildings. Reference table for u values u value is the coefficient of transmission i e the transmission of heat through the materials which compose the building s envelope or outer shell.

A ledger is a horizontal board that is attached to the top of the the wall. Standard hollow blocks laid on their face and supported between steel joists make a structurally sound roof and far surpasse any code requirements. The only known roof systems that have consistently survived high category hurricane and tornado velocity winds have been built with structural reinforced concrete decks securely and sufficiently connected to structural reinforced concrete or reinforced concrete block walls. The concrete blocks are supported by steel joists that make concrete floors and roofs simple and affordable.

Roof deck and roof cover systems. The steel joists will provide a strong foundation for the flat concrete roofing. Walls that are constructed of concrete block that need to be covered with a roof will require the use of a ledger.
