Classification 0507.

0507-05 Roofwork construction and repair
Applies to contractors engaged in the installation or repair of roofing material on all types of new or existing buildings or structures. Roofing materials include, but are not limited to, felt roofing paper, rolled composition, wood, fiberglass or composition shingles or shakes, aluminum or sheet metal, masonry or ceramic tile, tar, and polyurethane foam. Installation of roofing materials varies with the product. Wood, fiberglass and composition shingles are nailed; masonry, slate or ceramic tiles require drilling, nailing or cementing; polyurethane foam is applied by spray then coated with a protective layer of paint-like material; hot tar requires melting in tanks, usually at ground level, then it is pumped or raised by bucket to the roof top and applied by spray or mop; cold apply uses an adhesive to bond roofing membranes to form a roofing system; cold tar is applied by brush, spray or mop; single ply involves large sheets of roofing material which are unrolled on the roof with edges overlapping and seamed; and metal roofing is seam welded or nailed. For purposes of this classification the term "roofwork" includes repairs to the subroof such as the replacement of trusses, rafters, supports, and sheathing, but excludes the placement of trusses, rafters, supports or sheathing on new building construction. Essentially, when removing the existing roof material from an existing building or structure it is not uncommon to find dry rot or deterioration to parts of the subroof. The repair of the subroof is part of the roof repair or replacement project and is included in this classification. By contrast, when a subroof is constructed on new buildings or structures, this activity is to be reported separately in the classification applicable to the work being performed such as 0510 for wood frame construction or 0518 for nonwood frame construction. This classification includes the installation or on-site maintenance of roofing materials composed of impermeable barriers, sod, soil, and plants, sometimes termed landscape roofing, living roofing, garden roofing, green/environmentally beneficial roofing, brown/biodiverse roofing, or vegetative roofing; and any installation or maintenance of a landscape roofing irrigation system.
This classification excludes roof cleaning, moss or snow removal on single story buildings not incidental to, or part of, a roofing contract which is to be reported separately in classification 6602; roof cleaning or moss removal of multiple story buildings not incidental to, or part of, a roofing contract which is to be reported separately in classification 0504; the installation of gutters and downspouts which is to be reported separately in classification 0519; waterproofing parts of buildings other than roofs which is to be reported separately in classification 0504 and/or 0101; placing roof trusses, rafters, supports and sheathing on new wood frame buildings which is to be reported separately in classification 0510; the application of polystyrene strips used as insulation on mobile homes which is to be reported separately in classification 0512; and placing roof trusses, rafters, supports and sheathing on new buildings, N.O.C. which is to be reported separately in classification 0518.
0507-99 Roofwork construction and repair (only to be assigned by the roofing specialist)
Applies to roofing contractors who consider themselves to be independent contractors, have no employees, and have not elected owner coverage for themselves.
The purpose of assigning this classification is to allow the independent contractor the opportunity to be checked for "account in good standing" for prime contractor liability.
Special note: Any contractor who hires employees or elects owner coverage is required to report in the applicable construction classification.
