International ClassE04D 013/10AbstractA roofing panel construction with at least one upstanding projection which holds accumulating precipitation in the form of snow in stasis from movement. Each projection has a smoothly rounded contoured back body with a front wall having a generally flat front outer face to arrest or inhibit the downward motion of accumulated snow or ice. The body of each projection is generally triangularly shaped in cross section throughout its longitudinal dimension for strengthening the body and wall under snow or ice loading. The front wall of each projection is disposed at an acute angle relative to the transverse dimension of its associated panel for helping to prevent the accumulation of standing water as accumulated snow or ice melts gradually. Similar projections are staggered and angularly displaced relative to one another. In another form of the invention, different types of projections are spaced apart and aligned relative to one another.Field of SearchCOVER WITH EXTERIOR HOLDDOWNCOVER WITH PROJECTING RESTRAINER; E.G., SNOW STOP STREAMLINE CROSS-SECTION; I.E., AIRFOIL Face-to-face tongue and groove; e.g., dado Meshing corrugated sheet type Fastener or anchor at juncture Lapped multiplanar surfacing attached to substructure arrangement Folded, rolled, or indented in situ IMPERFORATE PANEL WITH INTEGRAL REINFORCING | |
