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.
Claims6
A roof edge apparatus, said apparatus comprising:
- a drip edge that includes an upper edge and a lower edge wherein the lower edge sits under a roofing material along a roof edge;
- a base panel that sits over the drip edge but under the roofing material along the roof edge and provides a multilateral surface with four or more sides for laying a first row of roofing materials, wherein an outer side of the base panel is aligned with the roof edge;
- and
- an 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 wherein a narrow cut exists between the bottom of said inner slope and the base panel;
- and
- an outer slope that is parallel to the roof edge and facing the opposite side wherein the bottom of said outer slope is attached to the outer side of the base panel;
- wherein the 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 can be secured between the ridge structure and the base panel.
A method for constructing a ridge structure along a roof edge, said method comprising:
- screwing down a panel of metal on a roof edge wherein the panel projects beyond the roof edge;
- installing a roofing material on the roof, wherein the roofing material covers the screws on the panel but leave the portion of the panel projecting beyond the roof edge uncovered;
- making drain holes on the uncovered portion of the panel;
- and
- bending the uncovered portion of panel toward the roof surface.
