ABSTRACT:
Roofs like other portions of buildings expand and contract with temperature changes in various climates and seasons. Regardless of outside temperature conditions there is almost no contraction and expansion in the roof described. Means and methods are devised for excluding all moisture from roof joints, thus the freezing and thawing conditions which usually exist are here absent. Unlike other roofs there is no overall expansion and contraction to open cracks to receive dampness, or to require roof repair or replacement. This is a permanent non expanding and non contracting roof structure.
