Rafter Roof Load Bearing Wall

I am about to do some wall removal where the homeowner does not want a header between the rooms after the wall comes out.

Rafter roof load bearing wall.

In this roof design the exterior walls on which the roof s sloping rafters rest are load bearing walls. In lower storey load bearing walls. The tables permit a bearing length of up to 3 5 inches but since 1 5 is probably the worst case that you ll encounter for joist or rafter bearing it s a safe value you can get the compression perpendicular to grain design value for various species selected from the addendum that comes with design values for joists and rafters. I cannot find any information pointing to the need for an interior load bearing wall with this design.

Rafters 12 ceiling joists 15 hanging beams member16 underpurlins 17 strutting beams 18 roof beams 20 verandah beams 22 garage roof. Additionally a wall parallel to and within 2 or 3 feet of the joist may also be load bearing. Any joist or wall with a wall directly above running parallel might be a load bearing wall. Just to be on the side of caution i would install an 8ft 4x4 directly centered under the splice with lag bolts and remove the vertical.

The homeowner insists it is not a load bearing wall because the roof is built with a frame type trusses. Visit the roof framing page for more information on cutting roof rafters and visit the roof pitch calculator for determining rafter lengths based on rise and run. Although they don t bear the full weight load of the roof the gable end walls are also typically load bearing and an interior wall running parallel to the roof ridge in the center of the building often bears a load from the ridge. This house is a side split house and the area we are talking about is the side with no upper floors.
