re enforce garage to build loft


Hope someone can help me with this.

I have a very high garage roof but 3/4 of the way up the roof trusses start.
I think they are called Finch trusses made out of 2x4 and they have a w type re enforcemt to the bottom of the Joist.

I would like to remove the w Pattern and re enforce the top with 2x6 and frame the walls in 2x6 they are 2x4 now with a brick veneer.. once that is all done I would build the loft.

Does anyone know if this is possible or do I have to remove the whole roof and truss?

Never cut any truss for any reason.

You would need to have the truss evaluated for modification or replacement by the manufacturer.

You should have an engineer look at it.
Those trusses don't just hold up the roof, they keep the walls from spreading out.

The advice is the same. You can't just modify the trusses without knowing how, without possible dire consequences.

There is only one person qualified to tell you if you can modify your truss in any way, and that is the engineer at the truss manufacturer.

Look them up online and give a call -- the answer is probably a simple "no."

To do what you want, you probably need to tear off your roof and re-frame it.

good advice.

Engineered trusses are just that: "engineered." They are built so that they use the least amount of wood but are still strong enough to hold up the roof and transmit all the load to the exterior walls (typically). Plus they hold the tops of the walls in place. They do this by breaking up the framing into a series of triangles, which transmit loads in different directions. When they are connected these triangles form a unitary structure. Cutting any truss without a full recalculation of the loads and stresses involved is asking for truss failure.

Given that you want to build a loft, with associated live and dead loads, you may have to reinforce the walls as well, to take the extra loads.

Your best bet is to hire a structural engineer. But be prepared for him to tell you that it's going to be very expensive to do what you want to accomplish. As pyper said, you may have to remove the roof to reframe the whole thing.
