Bureau of Development Services Program Guide - Solar Water Heating and Photovoltaic Electric Generators 4111/ Installed on One or Two Family Dwellings Page 14 of 14 December 1, 2010 J Yes j No Is the roofing material metal,single layer wood shingle.or not more than two layers of composi- tion shylgle? J Yes j No Is the weight of the modules and racking less than 4.5 pounds per square foot? J Yes J No Is the module height less than 18 inches above the roof In accordance with section 305.4? For Standing Seam Metal Roofs Only(If not applicable please skip this section) J Yes J No Is the metal gauge 26 or heavier? J yes j No Clamp design:Are damps designed to withstand uplift of at least 115 pounds for damps spaced at 80 inches on center or less of at least 75 pounds for damps spaced at 48 inches on center or less? J Yes j No Is the spacing of the clamps as measured along the seam greater than or equal to 24'o.c.and less than 80'o.c.AND the spacing perpendicular to the seam not greater than 24'o.c.? J Yes J No Is the roofing panel width 18-inches or greater? J Yes J No Is the roofing panel attached with at least e10 screws at 24'o.c.? J Yes j No Is the roofing panels installed over minimum 1/2-inch nominal wood structural panels attached to framing with 8d nails at 8'o.c.at panel edges and 12"o.c.field nailing? If you have indicated"No"on any of these requirements above,the project may not be submitted using the prescriptive path. Fire Fighter Access and Escape Arr.c non-occupiedand escape pathways are not required when the array is located on a accessorywuctures that 1.110 is separated from occupied structures by a 6 foot minimum separation distance or by a mnimum twolwur fire rated assembly. General Requirements:For all other roof mounted systems,a minimum 36"wide pathway is required along three sides of the solar roof.located over a structurally supported area. My roof with a slope greater than 2:12 cal not use the bottom roof edge as a pathway. Pathways and solar panels shall be located outside 12"of the low point of a valley. If the army is greater than 150 feet it length or width,additional 38"wide intermediate pathways and cutouts are required. See code for details. If the roof has smoke and/or heat vents,a 36'pathway shall be provided to and around each vent. Exceptions to General Requirements: J Yes :I No Is the roof slope greater than 2:12? Oyes NO Is the array area 1,000sq ft or less? J Yes JNo Is the anay 150 feet or less in length or width? If you have Indicated"No"to any of the items above,exceptions do not apply,provide a simple plan conforrning with the general requirements. If you have indicated"Yes"to all of the items above,see below for reduced access and escape pathway require- ments. Is the army 25%or less of the roof area? J Yes J No • If Yes,a 12'pathway along each side of any horizontal ridge is required. • If No,a 12"pathway along each side of any honantal ridge is required and a minimum of one 36'pathway is re- quired from ridge to cave over a structurally supported area. Provide a simple plan showing conformance to the reduced access pathway requirements. As the property owner or authorized representative of the above listed property,I certify that I have verified the information provided above and that the roof rafters(if applicable to the project),meet the span requirements of Table 305A.1(Appendix 0)of the Oregon Solar Installation Specialty Code.
