Content
Roof trusses are pre-assembled trussed rafters. The structure is fixed with toothed steel plate connectors pressed on the wood mechanically. Any roof can be customized and then ordered to an assembly plant. They will cut the wood at the specific measures and then deliver it ready for installation. Some of the disadvantages of using roof trusses is that they provide small spaces in the attic and also they need to be installed on top of flat ceilings. Tools and materials structural members framing hammer circular saw steel plate connectors nails, bolts measuring square plywood Structural members You will need to lay a pair of rafters in position on the ground. Full length joists are needed to span the entire width of the building. Now divide the bottom chords into thirds and mark it on the board. You will need to measure from the 1/3 point on each side of the bottom chord up to the midpoint of each rafter. After his measure from the 1/3 point up to the peak connection. Now join the bottom chord and the top chord with diagonal braces. Cut the ends of the braces on an angle. Connections Tooth plate connectors can be hammered onto each of the connections so that they grip the end member of the joint. You can also use plywood gusset plates. Cut the plywood so that it covers at least a foot of each member. Glue the gusset plates in place, and also use some nails for a better fixation. Installing the trusses

WHAT IS A ROOF TRUSS?
Roof trusses are frames made up of timber that is nailed, bolted or pegged together to form structurally interdependent shapes of great strength. Never remove, modify or cut into a roof truss without consulting a Structural Engineer: your roof could fall down!
Roof trusses have to withstand the weight of the roof timbers and coverings (the µDead Load¶), plus a factor for your local Wind Load, plus a factor for your local Snow Load, plus a Safety Factor. A Structural Engineer can check these figures - Property Repair Systems offers an independent, qualified Structural Calculation service, if you need to modify or repair your roof. Roof trusses come in all shapes and sizes to suit almost every single design of roof. If you cannot find the truss you need below you may need to find a good carpenter to build a traditional µcut¶ roof. This means that your roof is made up from timbers on site. If your existing r oof trusses are damaged in any way it is possible to repair them without taking your roof to pieces.
WHAT MAKES A TRUSS STAND UP?
The truss depends on three main characteristics, which can be given µnumbers¶ so that a Structural Engineercan calculate a safe load;
y
The strength of the timbers ± modern trusses are very lightweight, so only structural kiln dried timber is used and it is usually pre-treated, to prevent insect and rot attack. You can specify the TRADA Strength Grade when you buy timber ± for example, C16 or C24 ± if an Engineer supplies the Design information. The distribution of the load through the parts ± the design is critical ± if you take one component out, or weaken it (say by cutting notches for pipes) it will be seriously weakened

Conventional Roof Frames Conventional roof frames can shift the weight of the roof system to the perimeter walls and other load bearing interior walls. Load bearing capacities are determined by the size and spans of the lumber used to frame the roof system and the floor system. Conventional roof systems can be modified to accommodate living space, skylights, dormers and other structural changes with relatively little modification.

Types of Roof Trusses
A roof truss is a building material used to frame and support the roof structure of a home. While traditional roof framing was built on-site using lumber or steel, the majority of new homes today are built with premanufactured truss systems. There are many different types of roof trusses available to accommodate different home designs and roof loads.
Types
1. While many different trusses are available for roof construction, they can usually be broken down into one of two basic categories. Flat trusses, known as parallel-chord or girders, are used to construct flat roofs. Pitched, or common, trusses are used to build sloped-roof structures. Hip, gambrel or bowstring designs are popular examples of common trusses.
Identification
2. All types of trusses have the same basic components and structure. The name "truss" describes a triangular design, which may range from a simple individual triangle to alarge number of interconnected units. The outside framing members are known as chords, while the smaller connecting members are called webs. A point where the truss rests on a load-bearing wall is known as a bearing point, and a king post is a vertical support that divides the bottom chord on many types of trusses.
Function
3. Roof trusses are used to carry and support the weight of the roof deck and any finish material used to cover the roof. This weight can be quite significant if clay or slate roof tiles are used, or it may be very light when used to support asphalt shingles or rolled roofing. The chords support the roof while the webs brace and stabilize the chords, helping to distribute the load across the entire truss to the bearing walls on either side.
Benefits
4. One of the primary benefits to truss construction is the ability to span much longer areas than with traditional stick framing. Because trusses are designed by engineers, they are also safer and more reliable
than alternative materials. Truss roof systems can be erected much more quickly and efficiently than framed roofs, and a variety of different truss designs are available offer versatility to builders and homeowners.
Drawbacks
5. Because of the triangular shape of a truss, homeowners will find that roof trusses can greatly reduce the amount of usable space in the attic. This can cause problems with storage, or may even cut into potential living space. Trusses are also generally more expensive than stick framing in terms of upfront cost, though the associated labor savings may offset this higher material cost.

Roof trusses serve a pair of critical functions for a building. There are many different types of roof trusses. Which truss design to use depends on a number of factors and that decision is best left to a professional engineer.
What Is a Roof Truss?
1. A roof truss is a frame, typically made out of wood. The frame is composed of a series of connected triangles as that particular shape has great structural stability.
What Does a Roof Truss Do?
2. A roof truss does a couple of different things. Primarily, it supports the components of a home's roof, including roof sheathing, felt paper and shingles. Secondarily, a roof truss adds structural integrity to the home's envelope by helping tie it together from the top.
Why Are Roof Trusses Important
3. Without roof trusses a building would have no platform for a roof. Further, the building envelope would be significantly weaker.
