Roll Roofing

Abstract

A roll roofing material is provided in the form of a cylindrical roll that may or may not have an exterior covering thereon, and with transverse members being provided, carried by the cylindrical roll, and which protrude generally outwardly of an exterior cylindrical surface of the roll. The transverse members inhibit rolling of the roll roofing either off a pitched roof, or relative to a flat roof. One or more inserts may be provided in a hollow core of the roll, and connectors may attach a strap to these inserts for transporting the same from ground to a rooftop, or otherwise. Protective covers may be provided at opposite ends of the roll roofing, and the protective covers may comprise the transverse members, as may be desired.

Description

BACKGROUND OF THE INVENTION[0001]It is known in the roofing art to provide roll roofing material, formed into cylindrical rolls. Such roll roofing material will generally comprise asphalt saturated felts, which may function as starter strips on a roof, or as underlayments on a roof over which shingles may be applied. Generally, when used as starter strips, or as underlayments, the roll roofing material will be applied on sloped roofs. However, roll roofing material with or without mineral surfaces applied on the outwardly-facing surface may be placed on flat or nearly flat roofs or on sloped roofs. Sometimes granules or other minerals are applied in an embedded form to the outwardly-facing surface of the roll roofing material during its manufacture. In other cases, the outwardly-facing surface of the roll roofing material may be smooth, and may be applied to a flat or sloped roof, to which loose granules or stones may later be applied.[0002]Typically, rolled roofing is sold in boxes...

AI Technical Summary

Benefits of technology

[0006]In accordance with this invention, roll roofing is provided with end or other treatment that addresses the problem of stabilizing rolls on a roof, addresses the problem of photodegradation of adhesive at ends of the rolls, and which eases the transportability of rolls from ground level to rooftop.

[0007]Accordingly, it is a primary object of this invention to provide a novel roll roofing material of cylindrical configuration, in which a transverse member is provided, with portions protruding outwardly of the cylindrical surface of the roll roofing, such that when the roll roofing material is disposed on a roof, the transverse member will resist rolling of the roofing material off the roof.

[0009]It is a further object of this invention to provide a protective cover for one or more ends of the roll of roofing material, and most preferably, with a protective cover providing a shield that inhibits photodegradation of any adhesive at the end of the roll roofing material.

[0011]It is yet another object of this invention to provide connectors at opposite ends of the roll roofing material, with a carrying strap connected thereto, to facilitate transporting the roll of roofing material.

[0012]It is a further object of this invention, to provide a band disposed about the roll roofing, with the band being openable for movement from a cylindrical configuration to a more flattened configuration, to prevent rolling of the roll roofing material off a roof.

Problems solved by technology

However, the boxing-up of roll roofing can be resource-intensive during production, requiring additional labor to box the material and to then palletize the boxes.

Such packaging, when it is done, can cause a reduction in the speed of production lines.

For example, some adhesives, such as can be used on self-adhering membranes (roll roofing type) can be susceptible to ultraviolet degradation.

Other adhesives can also be susceptible to ultraviolet degradation.

Sometimes roll roofing material is placed in an opaque liner that covers the outside of the rolled roofing products, but often, even when the outside or cylindrical surface of the roll roofing material is wrapped with an opaque liner, the ends of the rolls can be exposed to ultraviolet light, thereby leading to adhesive degradation and loss of adhesive tack at the outermost edges of the roll roofing product.

Furthermore, when roll roofing materials are applied on a sloped or pitched roof the roofing may roll off the roof, creating a hazardous working environment.

Such undesirable rolling off a roof can be a problem not only for sloped or pitched roofs, but also for flat roofs.

Additionally, due to the size and shape of roll roofing, such roofing can be unwieldy and difficult to transport from the ground to the rooftop at a construction site.

For example, typical sizes of roll roofing can be 36 inches wide and, when unrolled from their cylindrical form to a flat form, can be 36 feet long, 72 feet long, 144 feet long, etc., which, considering the materials from which roll roofing are created, including generally asphalt-impregnated webs, with particulate material applied thereto, such as granules, talc, etc., the weight involved in having to transport roll roofing from typically a ground level to a roofing level, up a ladder or the like, can create difficult labor situations.
