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 "roof-work" 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.
Special note :
Any contractor who hires
				  employees or elects owner coverage is required to report in the applicable
				  construction classification.
