The most often asked questions about roof trusses . . .
and why trusses are used in 8 of 10 houses
built in the U.S. today.

What Is A Roof Truss?
A roof truss is a rigid, strong framework made up of wood members, such as 2" x 4"s, fastened and held together by metal connector plates. This framework accounts for the shape of your roof and supports the roofing materials. Roof trusses are designed according to ancient geometric principles. Many of the bridges you drive over were designed using the same principles.

Is Wood Roof Truss Systems Superior To Conventionally framed Systems?
All roof systems are adequate if properly designed, constructed and installed. Unfortunately, not all roof systems meet those criteria.

In our opinion, wood trussed roofs are superior due to professional design, high quality materials, uniformity of size and pitch, and the fabrication techniques used. 

Why Is A Wood Trussed Roof Better?

Lumber used by quality truss manufacturers conforms to strict state, local, and national building design criteria.

Lumber for trusses are cut by machines that are mathematically calibrated and set to produce highly accurate cuts. This helps eliminate gaps when truss members are joined.

Because trusses are manufactured with great precision in jigs, multiples of the same trusses are identical in size, assuring uniformity throughout your roof system.

In conventional building most carpenters can cut and build a roof. But, much is left to chance and the builder's opinion. However, most trussed roof systems are designed by engineers or architects to fit your specific roof system and conform to applicable building codes.

Most trusses are fabricated under ideal shop conditions and therefore, are not usually subjected to a great deal of exposure to inclement weather until delivered to the site.

Your house is closed in more rapidly with roof trusses thus reducing the time interior walls and floors are exposed to the weather.

If installed properly roof trusses are designed to eliminate deflections. You get even, level ceilings and less chance of plaster or drywall cracks.

What Holds The Wood Truss Members Together?
High quality metal connector plates. Their holding values and strength have been determined through years of intensive laboratory testing.

How Long Will Our Roof Truss Systems Last?
With normal maintenance and repair -- such as replacement of shingles, flashing, etc.-- your roof system should maintain its structural integrity for the lifetime of the house, barring fire or some other disaster.

How Safe Is A Wood Trussed Roof System In Case Of Fire?
Fire is a hazard that can never be ignored regardless of the kind of building system. Immediate safety precautions should be taken upon discovery of any fire.

In most instances, trusses are considered separate, independent structures designed to support certain defined conditions. The structural integrity of most wood roof trusses is not dependent on other trusses. As a result, one truss may burn and even collapse while other portions of the roof remain standing. In many cases this allows additional time to evacuate the building.

Following Installation, Are Wood Truss Systems Inspected For Quality, Conformity, And Design Integrity?
Where building code departments exist, enforcement officers normally inspect all phases and parts of a building. This, of course, would include your wood roof trusses. We support and help determine interpretation of the codes for that area.
