Criteria is as follows: 1. Existing roof framing: Conventional roof framing at R2 is 2x6 at 24 o.c.; existing rafter span= 12' 0" with an existing kneewall at approximately mid-rafter span; (horizontal projection) Conventional roof framing at R8 is 2x6 at 24 o.c.; existing rafter span= 5' 0"; (horizontal projection) 2. Roof Loading: • 3.0psf dead load (pounds per square foot - PV panels, mounting rails & hardware) • 5.7psf - existing roof loads (1.7 psf - 2x6 framing, 1.5psf roof sheathing, 2.5 psf shingles) • Ground Snow Load - 30psf - per ASCE Hazard Tool • Wind criteria - Exposure Category B, 140 mph wind 3. Existing Roof modification - none required; existing roof framing is acceptable for PV installation. This installation design is in general conformance with the manufacturers’ specifications and complies with all applicable laws, codes, and ordinances – specifically the International Building Code (2015 edition) and the International Residential Code (2015 edition), including all Massachusetts regulations and amendments. The spacing and fastening of the mounting brackets is a maximum of 48” o.c. between mounting brackets (staggered) and is secured using 5/16” diameter corrosive-resistant steel lag bolts. A minimum of 2½” of penetration (embedment) per lag bolt is required, which will resist all stated loads above – including wind shear. Per NDS Section 12.1.4, clearance holes - equal to the diameter of the shank - need to be bored into a primary framing member for the full-length of the threaded portion of the bolt to avoid splitting of the framing member.
