Construction contractors often use roof trusses because they can save a lot of time. In fact, the vast majority of homes built in the United States use trusses. When working with trusses, there are several things to keep in mind if you want to make the construction job easier.
Order the trusses as soon as possible. The more complicated the order, the longer it will take for the trusses to arrive. You can expect trusses to take as long as eight weeks to arrive. The larger your roof will be, the more lumber you'll need. Measure the square feet of the building to determine the dimensions you'll need for the trusses.
Have Set Plans
Make sure that your plans are firmly set before you order trusses. If you make changes to your plans, you'll need to send the trusses back to have them remanufactured so that they fit your new plans.
Decide Whether to Buy Prefabricated Trusses
Decide whether you want to build the trusses yourself or order prefabricated trusses. Building your own truss can save you money, but it is much easier to order a truss that has already been constructed, and that way, you don't have to worry about making a mistake when creating your truss.
Choose the Right Trusses
Reclaimed timber trusses are a better option than green wood trusses because they are more stable. Many property owners also prefer the character that reclaimed timber trusses add. The type of truss you'll need is also based on the type of home you have. If you have a Colonial-style home, you'll need a different truss than if you have a Cape Cod–style home. If you want a very high ceiling, you might need scissor trusses. The home will look different based on the type of trusses used.
Match Old Trusses with New
If you are adding new trusses to existing trusses, the new trusses need to match the old ones. When ordering, include the slope, span, and heel height. The heel height is often a characteristic that is not included.
Use Metal Connectors
The trusses always need to be connected using metal connectors. Do not simply screw the wood together because your trusses will not form the necessary triangular construction. Also, make sure to add perpendicular supports to distribute the weight load and add vertical support that angles from the bottom of the center support on each side. As long as you take the right steps, you'll be able to construct a stable roof.
