The Variety of Truss Types Can Be Staggering…
Here Are The Most Common Trusses

You’ve been sitting down with your potential house plans and are trying to decide if framing your roof by hand is better than ordering trusses for your house. Building your own stick-framed roof could save you some time and money.

Taking your plans to a home building supply store that specializes in building truss types will quickly tell you if doing pre-built trusses for your house is feasible.

Here are the more common truss types available:
