All other data can be found in the 2012 International Residential Code Rafter Spans.Be sure to use rafter clips on every rafter not nailed into a ceiling joist. Roof snow load is defined as the weight of snow on the roof surface used in design of the building structure (IBC, 2012). Tables in the Span Book and the National Pilot Rock® is a registered trademark of RJ Thomas Mfg. It is defined in Eurocode 1 (NF EN 1991-1-3 Eurocode 1 â Actions on structures â Part 1-3: general actions â Snow loads (P06-113-1: 2004-04, NA: 2007-05, A1: 2015-10, NA / A1: 2011-07, NA / A2: 2012-09). The shapes and spans shown here represent only a fraction of the millions of designs produced by Alpine engineers. Selection Tables (Tables 1-4, 7- 10 and 15-18) have been sized using the Design Roof Snow Load shown in. Tables 1 and 2 are generated assuming dry conditions, normal duration of load and untreated, Exposure 1, structural pan- els. Many planning departments have tables that relate truss size, pitch and materials to the pressure from snow or other factors. Express the result in feet rather than inches.
