Abstract
An assemblage of sheet metal roof covering pieces is utilized in a novel process to recover and stiffen a deteriorated roof without the necessity for extensive removal of the original roof covering, the deteriorated roof structure further stiffened by spaced stiffening ribs that also serve to fix in interlocked engagement the sheet metal roof covering pieces. Included in the assemblage are interlocking valey pans that are sequentially compressed between the ribs and then fastened with the valley pans then bridged by curved sheet metal caps that are also interlocked. The resulting structure has the pleasing appearance of an Oriental tile roof.
Claims12
A method of repairing an existing roof covering comprising the steps of:
- covering said roof covering with a generally flexible sheet;
- affixing a plurality of generally vertically aligned elongate ribs to the exterior of said roof and on top of said sheet covering selected one of said ribs being aligned over beams supporting said roof;
- interlocking a plurality of sheet metal valley pans each of a generally rectangular planform of a width greater than the separation between said ribs, each said valley pan including opposedly folded transverse edges for effecting a stepped interlock progression thereof;
- compressing in sequence said valley pans into the space between the adjacent ones of said ribs and in the course of such compression bending the surface thereof so that the longitudinal edges of each sid valley pan overlie the sides of the adjacent ribs;
- fastening said longitudinal edges of each said compressed valley pan to the proximate lateral surfaces of said adjacent ones of said ribs;
- interlocking a plurality of sheet metal caps to each other in a longitudinal alignment, each said cap including opposedly folded transverse edges for said effecting a stepped interlock progression;
- and
- bridging each said rib and the valley pan edges attached thereto with said caps by bending each said cap in its interlocked alignment for attachment thereof to said ribs.

A method of repairing an existing roof comprising the steps of:
- covering said roof with a generally flexible sheet covering;
- affixing a plurality of generally vertically aligned elongate ribs to the exterior of said roof and on top of said sheet covering;
- interlocking a plurality of sheet metal valley pans each of a generally rectangular planform of a width greater than the separation between said ribs, each said valley pan including transverse edge folds for said interlocking step;
- compressing in sequence said valley pans into the space between the adjacent ones of said ribs and in the course of such compression bending the surface thereof so that the longitudinal edges of each said valley pan overlie the sides of the adjacent ribs;
- fastening said longitudinal edges of each said compressed valley pan to the proximate lateral surfaces of said adjacent ones of said ribs;
- interlocking a plurality of sheet metal caps to each other in a longitudinal alignment;
- and
- bridging each said rib and the valley pan edges attached thereto with said caps by bending each said cap in its interlocked alignment for attachment thereof to said ribs.

A method of re-covering an existing roof cover, comprising the steps of:
- covering said existing roof cover with a layer of generally flexible sheet covering;
- affixing a plurality of generally equally spaced vertically aligned elongate ribs selected from standard dimension construction lumber to the exterior of said roof and on top of said sheet covering, selected ones of said ribs being aligned with the beams subjacent said roof;
- interlocking a plurality of sheet metal valley pans each of a generally rectangular planform of a width greater than the separation between said ribs, each said valley pan including opposed transverse edge folds conformed for said interlocking with the corresponding fold in the next valley pan;
- compressing in sequence the interlocked edge of each said valley pan into the space between the adjacent ones of said ribs and in the course of such compression bending the interlocked transverse edge and the adjacent surface thereof so that the longitudinal edges of each said valley pan overlie the sides of the adjacent ribs;
- fastening said longitudinal edges of each said compressed valley pan to the proximate lateral surfaces of said adjacent ones of said ribs;
- interlocking a plurality of sheet metal caps to each other in a longitudinal alignment;
- and
- bridging each said rib and the valley pan edges attached thereto with said caps by bending each said cap in its interlocked alignment for attachment thereof to said ribs.
