Abstract

A flashing system and assembly for slate or tile roofs having a flashing and a flashing cap. The flashing is shaped to replace a plurality of removed slates or tiles. The flashing cap has an adjustable position such that the position of a mounting rail support system passing through the flashing can be adjusted with respect to the flashing while still maintaining a watertight seal with the flashing cap and optional sealing cap.

First claim

What is claimed is:

1. A flashing system for a photovoltaic (PV) mounting rail support assembly, comprising:
a mounting bracket with a plurality of mounting holes for attachment to a roof component;
a flashing having a body portion, at least one tab portion, and an opening with upwardly extending edges defining a first aperture passing through the flashing to reveal the mounting bracket, wherein the upwardly extending edges extend upward from the flashing;
a mounting rail support assembly affixed to the mounting bracket and passing through the first aperture, wherein the first aperture is substantially rectangular with rounded corners;
a flashing cap receivable to cover the upwardly extending edges defining the first aperture, wherein the flashing cap defines a second aperture for receiving an upwardly protruding support body of the mounting rail support assembly, and
a sealing cap for sealing against the second aperture of the flashing cap, the sealing cap defining a third aperture configured for sealing against the upwardly protruding support body of the mounting rail support assembly.

2. The flashing system of claim 1 , wherein the second aperture within the flashing cap is configured to match a shape of the support body.

3. The flashing system of claim 1 , wherein the flashing is a slate flashing and is configured to replace three roof slates in two adjacent courses, wherein tab portion has a width substantively equal to one roof slate and the body portion has a width substantively equal to two slates and is offset from the tab portion.

4. The flashing system of claim 1 , wherein the flashing is a tile flashing and is configured to replace four roof tiles, wherein the tile flashing has an first tab portion with a width substantively equal to one roof tile, a body portion with a width substantively equal to two roof tiles, and a second tab portion with a width substantively equal to one roof tile.

5. The flashing system of claim 1 , wherein the first aperture passing through the flashing is shaped to accommodate the mounting rail support assembly passing therethrough, and wherein a position of the mounting rail support assembly is laterally adjustable within the first aperture in the flashing.

6. The flashing system of claim 5 , wherein adjusting the position of the mounting rail support system adjusts the position of the flashing cap, but does not adjust the position of the flashing.

7. The flashing system of claim 6 , wherein the flashing cap covers and seals the first aperture in the flashing regardless of the position to which the flashing cap has been moved to adjust the position of the mounting rail support assembly.

8. The flashing system of claim 1 , wherein the main body of the mounting rail support assembly is cylindrical and a second aperture in the flashing cap is cylindrical.

9. The flashing system of claim 1 , wherein the upwardly extending edges of the first aperture in the flashing further comprise upwardly facing edges forming a base with a perimeter.

10. The flashing system of claim 9 , further comprising a gasket positioned around the perimeter of the base formed by the upwardly facing edges of the aperture in the flashing.

11. The flashing system of claim 10 , wherein the flashing cap is positioned on top of the gasket.

12. The flashing system of claim 1 , wherein the flashing is dimensioned to span two or more consecutive tile courses.

13. The flashing system of claim 1 , wherein the sealing cap is generally ring-shaped.

14. The flashing system of claim 1 , wherein the flashing cap is larger than the first aperture in the flashing and extends over a top of the first aperture in the flashing.

15. The flashing system of claim 9 , wherein the flashing cap has outer edges that pass downward around the base formed by the upwardly facing edges of the first aperture in the flashing.

16. The flashing system of claim 15 , wherein the flashing cap can be moved side-to-side to accommodate for positioning of the mounting rail support system.
