Install baffles providing a minimum of 1 inch of clear space between framing and or under roof sheathing at eaves to insure that ceiling or roof insulation does not block ventilation paths.

Roof truss ridge blocking.

The 200 pounds of uplift force allowed by the irc does not take into account the nailing between the trusses the blocking and the top plate when blocking is provided. A complex roof with more than four hips and with valleys due to wall jogs means that there are usually cases where trusses don t conveniently come to a hip and ridge line junction. Pitch for a gable roof the most common is generally 1 4 or 1 3. Each block is 2x4 or 2x6 depending on the size of the rafters and is secured to the top plate.

Blocking or boundary member. There is an unquantified load path resistance interaction present. Minus ridge thickness to allow for ridge becoming pole plate roof peak will be slightly higher ridge thick must be same. Pitch is the slope or angle from the wall plate to the roof ridge line.

Pitch can vary a great deal from a shallow slope up to a very steep pitch. Rafter blocking is an essential part of the roof framing process in that the blocks provide a stop for ceiling insulation and a continuous surface for the roof sheathing to be edge nailed to. In irc table r602 3 1 at right blocking between roof trusses is required to be fastened to the top plate with three 8d 2 long x 0 113 diameter toe nails. In my experience traveling across the country observing wood framed construction it was apparent that east of the rocky mountains structural wood members in line with supporting walls between roof framing cease to be installed.

Porch roof extensions for hip roof porch extensions from an existing building wall you can use half the calculator results. Where required by this section blocking between rafters or roof trusses shall be attached to top plates of braced wall panels and to rafters and roof trusses in accordance with table r602 3 1. For vaulted or cathedral roof construction provide free ventilation path from eaves to ridge between all rafters. Some may call these wood members blocking and deem them as optional.

Which is equal to 1 4 or 1 3 the total span of the building not counting any overhang. The pics show a view of such a roof a plan view of trusses and blocking at and near the intersect and a 3d model of the three pieces of 2x blocking that fills.
