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.

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. 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. Walls that are constructed of concrete block that need to be covered with a roof will require the use of a ledger. U value has an inverse relationship to r value.
