Scissor Truss Over Existing Roof

These types of trusses are often used to create multilevel roof lines or construct additions to an existing building.

Scissor truss over existing roof.

For a 2 000 square foot home roof truss installation typically costs between 7 200 and 12 000 you ll spend anywhere from 1 50 to 4 50 per square foot for materials alone or between 35 and 150 though extremely long and complex types can reach 400 each labor runs anywhere from 20 to 75 per hour ranges in both materials and labor are due to location size and roof complexity. If you modify the existing trusses i have one suggestion. These steel joints are needed to support the overall truss. The likely design option may involve removal of the existing trusses and replacing them with a scissors truss system which uses about 50 percent of the pitch of the existing roof.

This is the distance between trusses. A cantilever truss allows for level coverage past the exterior wall such as patios porches entryways and other offsets in the building elevation by moving one or both bearings inward from the end of the bottom chord up to 1. Replacing a roof can be expensive but if a roof contains only a small slope it s possible to raise the roof pitch of a house by building a roof over the old one. The more complex the truss framework is the greater quantity of these joints will be required.

The engineer must compute the roof load such as snow accumulation roofing materials and other factors. The steeper the roof the more expensive the trusses get because the longer the boards get and the more roof area increases. If the house is new enough that you know how built the trusses give them a call. This new roof with a higher pitch can be accomplished with premade roof trusses and typical asphalt shingles.

Rather than trying to make a scissor truss do a raised center. The standard roof truss spacing is 2. A mono truss is a one sloped truss that forms a right angle triangle. Finally the truss calculator will compute the best dimensional method to connect the pieces of the truss with steel joints and a bridge.
