Skylight flashing
A seamless skylight flashing has a frusto-conical curb defining an open top that can be covered by a skylight dome and an open bottom. A flat skirt extends radially away from the open bottom. Plural strengthening ribs are oriented radially on the skirt, and a peripheral rib is formed on the outer edge of the skirt. The skirt is preferably formed by die presses.
1. A tubular skylight comprising:
a seamless metal flashing;
a transparent dome engageable with the flashing;
at least one skylight tube depending downwardly from the flashing, wherein the flashing comprises:
a hollow frusto-conical shaped curb defining an open top, the open top being covered by the dome, the curb defining a bottom opposite the open top and not including a strengthening rib; and
a skirt extending radially away from the bottom of the curb, wherein the skirt defines a radial dimension, and the skirt is formed with plural ribs, each rib being oriented radially on the skirt, the skirt defining an outer periphery, a peripheral rib being formed along at least part of the periphery, the skirt not extending beyond the peripheral rib.
2. The skylight of claim 1 , wherein the curb defines a right regular conical frustum.
3. The skylight of claim 1 , wherein the curb defines an oblique pitch relative to the skirt.
4. The skylight of claim 1 , wherein the curb defines a vertical axis, the skirt blending into and extending outwardly away from the bottom in a radial dimension that is orthogonal to the axis.
5. The skylight of claim 1 , wherein at least the curb is seamless.
6. The skylight of claim 1 , wherein the skirt defines an upper surface and a lower surface, the peripheral rib rising above the upper surface.
7. The skylight of claim 1 , wherein the skirt defines an upper surface and a lower surface, the peripheral rib extending below die lower surface.
8. The skylight of claim 1 , wherein the peripheral rib is thicker than the skin.
9. The skylight of claim 1 , wherein the peripheral rib has the same thickness as the skirt.
10. The skylight of claim 1 , wherein at least one rib is trough-shaped.
11. The skylight of claim 1 , wherein the plural ribs are radial ribs, and at least one radial rib rises in a curve above an upper surface of the skirt.
12. The skylight of claim 1 , wherein the plural ribs are radial ribs, and at least one radial rib dips below a lower surface of the skirt.
13. The skylight of claim 1 , wherein the plural ribs are radial ribs, and each radial rib has a concave surface and an opposed convex surface, the concave surface being contiguous to an upper surface of the skirt and the convex surface being contiguous to a lower surface of the skirt.
14. The skylight of claim 1 , wherein the plural ribs are radial ribs, and each radial rib has a concave surface and an opposed convex surface, the concave surface being contiguous to a lower surface of the skirt and the convex surface being contiguous to an upper surface of the skirt.
15. The skylight of claim 1 , wherein the plural ribs are radial ribs, and the thickness of each radial rib Is equal to the thickness of the skirt.
