US 4,498,267 A · Simulated clay tile roof construction and method of making same

Abstract

A simulated clay tile roof construction is provided which includes a plurality of roof panel members which are each formed to simulate the appearance of a plurality of clay roof tiles. To minimize the weight and ease the assembly of the roof panel members, they are provided with cut-out sections at diagonally opposite corners. To optimize the strength and minimize the weight and cost of the panel members, they are constructed by molding with an upward facing weather resistant gellayer over the entire surface, with an underlayer of fiberglass reinforced gypsum over a majority of the surface thereover, and with a high strength underlayer of fiberglass reinforced plastic along the lateral edges thereof. A method of making the roof panel members is also proposed, including applying the fiberglass for the gypsum layer while the underlayer is still wet, applying the gypsum to the fiberglass layer, and then rolling the layers to mechanically bond the same together.

Dependent claims

A simulated clay tile roof construction comprising at least one unitary roof panel member formed to simulate a plurality of clay tiles;

said roof panel member being generally rectangular and having a series of raised partial cylindrical portions joined by flat portions;
the longitudinal edges of said roof panel member being located at raised partial cylindrical portions, for overlapping or underlapping raised partial cylindrical portions of longitudinal edges of adjacent roof panel members when in an in-use position forming a roof;
edge regions located at lateral edges of said roof panel member for overlapping or underlapping by engaging corresponding edge regions of adjacent roof panel member when in an in-use position forming a roof;
diagonally opposite cut-out corner sections on raised partial cylindrical portion edge regions for abuttingly engaging corresponding cut-out sections of diagonally adjacent roof panel members when in an in-use position forming a roof;
and
diagonally opposite non cut-out corner sections being solid for overlapping or underlapping the abutting cut-out sections of adjacent roof panel members when in an in-use position forming a roof.
