Abstract
Abstract Disclosed is an improved mansard type roof and a method of installing same. Roofing panels, made of expanded clay, foam, waterproofing, and wire mesh are provided in a form and shape that permits the panels to be assembled in horizontal rows with the upper and lower edges of adjacent panels overlapping to provide a watertight joint. Special vertical connection members are provided to assure watertight sealing between the vertical edges of adjacent panels and special means are provided to join the top row of roofing panels to the flat portion of the roof that overlies the majority of the building or house. The construction and installation of the roofing panels according to the disclosed method eliminates the need for separate waterproofing membranes and insulating layers and provides a fire resistant, waterproof roof of any desired color and surface configuration.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
183 words
A roof construction comprising a plurality of roofing panels arranged in horizontal rows upon a supporting frame structure, vertical joints between adjacent panels being sealed with an element provided with an upstanding flange having a height less than the thickness of the panels, said element being located between said supporting frame structure and the back surface of said panels so as to contact a portion of both of said adjacent panels, the vertical edges of said adjacent panels having a recessed portion extending from the back surface to a position spaced from the front surface for accommodating said upstanding flange and, at the same time, allowing the front surface of said adjacent panels to contact each other in their assembled position, said element having a coat of plastic roofing cement to form a resilient layer between said element and the back surface of said panels, and horizontal joints between adjacent panel rows being sealed with sealing means integrally formed with said panels, said roof construction being characterized by the absence of an additional water-proofing membrane between said panels and said supporting frame structure.
Claim 2
Dependent Claim
183 words
A roof construction comprising a plurality of roofing panels arranged in horizontal rows upon a supporting frame structure, vertical joints between adjacent panels being sealed with an element provided with an upstanding flange having a height less than the thickness of the panels, said element being located between said supporting frame structure and the back surface of said panels so as to contact a portion of both of said adjacent panels, the vertical edges of said adjacent panels having a recessed portion extending from the back surface to a position spaced from the front surface for accommodating said upstanding flange and, at the same time, allowing the front surface of said adjacent panels to contact each other in their assembled position, said element having a coat of plastic roofing cement to form a resilient layer between said element and the back surface of said panels, and horizontal joints between adjacent panel rows being sealed with sealing means integrally formed with said panels, said roof construction being characterized by the absence of an additional water-proofing membrane between said panels and said supporting frame structure.
Claim 3
Dependent Claim
53 words
The roof construction of claim 1, wherein said sealing means integrally formed with said panels comprises a lap joint surface formed along the upper edge of said panel of a shape complementary to the bottom edge of said panel in said adjacent row whereby said upper edge is positioned over said bottom edge.
Claim 4
Dependent Claim
22 words
The roof construction of claim 2, wherein a layer of plastic roofing cement is positioned between the overlapped portion of said panels.
Claim 5
Dependent Claim
47 words
The roof construction of claim 2, wherein the lower edge of said panels has an irregular appearing but periodically repeating shape, and a portion of said lap joint surface on said panels has a complementary irregular appearing, periodically repeating shape offset from that of the lower edge.
Claim 6
Dependent Claim
66 words
The roof construction of claim 1, wherein said supporting frame structure slopes downwardly and forwardly towards the eaves of the roof and said upper edge of said supporting frame structure is attached to a flat, horizontal roof portion that is of a size to overlie the majority of the building to be covered by said roof whereby only said roof construction is visable from ground level.
