DETAILED DESCRIPTION

[0017] As discussed above, embodiments of the present disclosure relate to flashing and more particularly to a metal roof flashing system as used to improve the flashing of roofs.

[0018] Generally, the present invention provides users with a residential or commercial pipe flashing used suitably for providing an effectively watertight seal around virtually all plumbing vent stacks on a roof or sidewall. It preferably includes a triangular base with a rubber conical vent support and lower flashing seal capable of being applied to the roof or sidewall in order to prevent water backup or flow beneath the surface. It prevents leaks and costly repairs within a home, office, etc. As designed, it reduces the visibility of flashing vent stacks and thus functionally improves the look and durability of a home or other building. The present invention can be made in numerous sizes and configurations to accommodate virtually any roof (slope) or sidewall area. The triangular base can be laid over the surface and traced for modular installation. After suitable cuts are made, the system can be installed over the hole and sealed. The system is intended to form a watertight seal around all plumbing vent stacks. The system can be constructed using rubber, metal, and other suitable materials. The flashings can be available in various sizes in order to accommodate all user needs and preferences. Exact size, measurement, construction, and design specifications may vary upon manufacturing.

[0019] Referring now more specifically to the drawings by numerals of reference, there is shown in FIGS. 1-5, various views of a metal roof flashing system 100.
