Scissor Truss Over Existing Roof

If you modify the existing trusses i have one suggestion.

Scissor truss over existing roof. 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. It s often used for sheds garages or extension of an existing roof. The engineer must compute the roof load such as snow accumulation roofing materials and other factors. Rather than trying to make a scissor truss do a raised center.

A mono truss roof allows for more sunlight and visual space proper drainage and relatively cheaper. The steeper the roof the more expensive the trusses get because the longer the boards get and the more roof area increases. This new roof with a higher pitch can be accomplished with premade roof trusses and typical asphalt shingles. 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.

These types of trusses are often used to create multilevel roof lines or construct additions to an existing building. Finally the truss calculator will compute the best dimensional method to connect the pieces of the truss with steel joints and a bridge. You will also incur additional costs because it is much harder to deck and shingle a roof that is 12 12 pitch versus a 4 12 roof. See more ideas about scissor truss pole barn homes barn house.

A mono truss is a one sloped truss that forms a right angle triangle. This is the distance between trusses. That way the last few feet at each end of the truss will not have to be modified and the changes should be less extensive.

If the house is new enough that you know how built the trusses give them a call. 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. The same thing is true for the bridge of the truss. The more complex the truss framework is the greater quantity of these joints will be required.

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.
