Dual pitched, square, low profile, galvanized metal roof flashing for rigid tubular daylighting systems.

Abstract

A galvanized metal flashing for the rooftop portion of a rigid tubular sunlight system, consisting of a flashing assembly (det. 12 ), with square walls, two of which are tilted at an angle of 5 degrees off vertical (det. 14 ), having an inner plate tilted at 15 degrees off horizontal (det. 16 ), and a center hole in said inner plate (det. 20 ), said hole providing a connection with a commercial rigid sunlight tube (det. 22 ).

1 . We claim a square, manufactured metal roof flashing with two pitches (angles) that allow the flashing to connect to a commercial metal tube to project sunlight down into a room below the roof.
 1) One pitch (angle) is in the form of a plate welded inside the flashing assembly, tilted at a 15 degree angle, which allows the commercial tube that connects to it, to go down in a straight vertical angle to the room below.   2) the second pitch (angle) is created in two vertical sides of the flashing box to allow the tube to clear or go past the sidewall of the flashing when it sits on the roof at an angle: These angled sides are situated at the “uphill” and “downhill” sides of the square box.   We also claim a low profile design which allows our flashing to be installed on roofs in areas that have “homeowner associations” which will not allow our competitors to install their high profile flashings on roofs in their areas.   A final claim is that we have a unique flashing that can be used on any roof, compatible with any roofing material, composition, tile, ceramic, shake, metal. There is no need to add extra skirting to our flashing to make it effective. All other competitors must add special skirts or other additions to their flashings to keep them from leaking, or having other problems with certain roofing materials.
