Synthetic Roofing Shingle

Abstract

A monolayer synthetic or artificial thatch shingle comprising a plurality of tapering extensions extending from a base flange member, the thatch shingle having been formed from a thin sheet of stiff plastic, and the extensions having been formed by removing material from the thin sheet. The base flange member presents a solid surface, such that when shingles are overlaid in successive rows advancing up the pitched roof, the combination of overlapping base flange members provides a water barrier such that all rain water is directed from the slanted roof.

Description

[0001]This application claims the benefit of U.S. Provisional patent Application Ser. No. 61 / 760,794, filed Feb. 5, 2013.BACKGROUND OF THE INVENTION[0002]This invention relates general to synthetic or artificial roofing shingles or similar products used as the external covering on a roof, wherein the synthetic shingles are manufactured to resemble and present the appearance of a natural roof covering once installed.[0003]Roof coverings composed of natural plant materials, such as reeds, grasses, palm leaves or the like, are well known in many parts of the world. Such roof coverings are often referred to generically as thatch roofing. A significant market for thatched roofing has developed, and in particular for synthetic or artificial thatched roofing, since the useful lifespan of the natural materials is relatively short when compared to the useful lifespan of synthetic thatch roof covering, which is made from one or more polymers, such as for example high density polyethylene (HDP...

AI Technical Summary

Benefits of technology

The invention is a type of roof shingle made from a thin, flexible plastic sheet. It has special features, like pointed or tapering extensions that give it a natural look. The base flange member is made from a solid sheet, which acts as a water barrier to prevent rain from leaking into the roof. The shingle is designed to have ridges or waves on its surface, which make it easier to install and provide a better appearance. Overall, this new type of roof shingle is biodegradable and more durable than traditional shingles.

Problems solved by technology

A waterproof underlayment is usually required, since this type of synthetic roofing shingle is not waterproof and primarily serves an aesthetic purpose.

The known synthetic thatch shingles also suffer from problems not inherent in the synthetic grass or reed shingles because of the broader width of the individual elements.

For example, in known synthetic thatch shingles, the finger-like extensions are susceptible being bent backwards and permanently crimped by strong winds.
