Roofing Framing

There are many different types of roof shapes from the basic gable to a mansard that can define the style of a building. For all types of roofs, the proper support is necessary in order to keep them from sagging or caving under pressure. Roof framing can be simple, but adding overhangs, hips and dormers to the roof can make it more complex. Pitched roofs have a series of frames that support the roof and its covering. Two basic types of framing used in many of the homes constructed today are stick-framed, or cut roofs, and truss-framed roofs. Consult with the Middlesex county roofers to find out which style they use in their roof constructions.

Stick-framed roofs are very basic and cut on-site while a building is being constructed. To create the support necessary for the entire roof, rafters are built spanning from the top of the interior walls to the ridge of the roof. When a larger span needs to be supported, some of the weight may be transferred to internal load bearing walls using purlin beams to form what is called a double-cut roof. Traditionally, stick-frames were used in all homes constructed, and despite being labor-intensive, the single- and double-cut roofs continue to be built today on homes with cathedral ceilings, attic rooms or attic storage areas.

Truss-framed roofs are made from premade truss units in triangular shapes that are often referred to as A-frames. Modern trusses are made at off-site companies that build the A-frames by combining the rafters, joists and jacks. A roof is made up of several A-frames are placed side by side and spaced every 16 to 24 inches from center to center directly above the interior wall studs. A truss is just as strong as stick framing, but it is lighter weight and uses smaller-sized lumber. They are not a good choice for roofs that might need to be modified later since they cannot be cut.

A truss can be recognized by the triangular shape and makes up the bulk of many new home truss packages. All of the truss parts can be combined to develop many types of different shapes and sizes in order to suit the needs of the different roof types. A few of the common types of rafters are the scissor, room-in-attic, hip and tri-bearing. All types of trusses can also be built to accommodate many different ceiling styles such as cathedral, vaulted, inverted and flat.

Term from the roofers at Fortified Roofing, Middlesex County NJ:


The room-in-attic truss uses the bottom chord of the truss as the floor joist. The support web is designed to create the frame of the walls of the room. This gives the ability to have usable attic space for storage or an extra room in a home.

Middlesex County roofers FAQ:

Is a wood-trussed roofing system safe in case of fire?

No matter what the building system or construction, fire is a hazard that cannot be ignored and safety precautions should be taken as soon as the fire is discovered. In a roof, each truss is considered an independent structure and will provide support under certain defined circumstances. In the case of fire, one truss can burn while others continue to support the roof. This can give homeowners additional time for evacuation.
