4W scl 40 SOUTHERNCOATINGSINC ROOFING Moisture Detection Tools In determining the soundness and dryness of a roof surface and underlying insulation, a device such as a Delmhorst meter is indispensable. These meters measure the moisture content of roofing materials. Moisture Meter FUR MR160 Imaging Roof Cleaning Equipment The commercial roofing tools and equipment listed below are needed for proper preparation: Stiff bristled hand broom — used for sweeping gravel and loose debris from the roof surface. Power broom — large motorized rotary brush used for thorough sweeping of large commercial roof areas. It weighs 400 to 500 pounds and requires use of a roof hoist. Spud bar (hand) — a long -handled, flat -bladed device used in much the same manner as an ice scraper for chip- ping and loosening embedded gravel. Power spudded — a motorized device which looks like a rotary lawn mower with steel blades. It removes embed- ded gravel quickly and completely. It weighs 300 to 400 pounds and requires use of a roof hoist. Garden hose with nozzle — used in conjunction with a hand or power broom for washing and scrubbing the sub- strate to remove all adhered or embedded dirt and contaminants. Shovel — used for removing aggregate and debris from the roof surface. Choose a sturdy industrial model. High pressure washer — machine to disperse water at very high pressure; used for water -blasting embedded dirt and poorly -adhered material from the roof surface. Vacuum/Hydrovac — Vacuum is a large truck or trailer mounted vacuum cleaner utilizing long, flexible hoses to vacuum loose aggregate from the roof surface. Note: Due to .high equipment cost, this procedure .is usually subcontracted. Hydrovac is an advanced vacuum which simultaneously vacuums loose material while washing and scrubbing the commercial roof with a rotating steel power broom and water spray attachment. The power broom and water serve to scrub the surface and flush out embedded dirt, which is then vacuumed away. This is a superior cleaning system, which does not introduce an excessive amount of water onto the roof, thereby avoiding delays due to a damp substrate. Backpack blower — a lightweight, motorized air blower which is strapped to the worker's back, freeing the hands to use the flexible hose to blow loose debris from the roof surface. 1 Air compressor — a large air compressor usually powered by a gasoline/diesel engine capable of producing a minimum air pressure of 100 psi with a minimum volume of 1.00 cfm. This high air pressure is used to blast loose material and debris from the roof surface. Trash chute — can be purchased or constructed from plywood and 2"x4" lumber. It is used to safely lower trash and debris from the rooftop to the truck or dumpster. Dumpster or truck — a dumpster, which can be rented, or a truck, which can be rented or purchased, is required when removing a significant amount of material from a roof.
