Abstract
A ridge structure at a roof edge, having a base panel lying on a roof surface and a hollow ridge structure over the base panel. The hollow ridge structure is constructed in a flat spring form along the eaves, and therefore one slope of the ridge faces the roof and the other slope the opposite direction. The slope facing the roof can be lifted to receive and secure roofing materials between the slope and the base panel. When water flows down the roof surface, most water flows over the ridge structure and the rest flows into the hollow space inside the ridge structure and drains through drain holes on the base panel.
Claims5
A roof edge assembly, said assembly comprising:
- a drip edge that includes an upper edge, an inner edge and a lower edge, and a flange portion extending between the upper edge and the inner edge, wherein the flange portion is positioned under a roofing material along a roof edge;
- a base panel positioned over the drip edge but under the roofing material along the roof edge, the base panel having a plurality of drain holes and an extended flange portion that provides a multilateral surface with four or more sides for laying a first row of said roofing materials, wherein an outer side of the base panel is aligned with the roof edge;
- and
- a unitary extension of the base panel that forms a ridge structure over the base panel, said ridge structure comprising:
- an inner slope that is parallel to the roof edge and facing one side thereof wherein a narrow cut is located between a bottom of said inner slope and the base panel;
- and
- an outer slope that is parallel to the roof edge and facing an opposite side thereof wherein a bottom of said outer slope is attached to the outer side of the base panel;
- wherein a curvature of the inner and outer slopes of the ridge structure forms a flat form spring pressing down on the base panel so that the roofing material is secured between the ridge structure and the base panel.
