What are roof trusses and why do I need them?

30 years ago, nearly every roof on every house was framed by hand. Now, with the growing complexity of designs and shapes of modern roof structures, most buildings take advantage of truss systems. A roof truss is a rigid, strong framework made up of wood members, such as 2x4’s, fastened and held together by metal connector plates. This framework determines the shape of your roof and supports the roofing materials. Roof trusses are designed to ancient geometric principles. Most of the bridges you drive over were designed using the same principles.

The advantage of trusses is that they offer a completely engineered solution to those complex roofs required by today’s home designs. Not only easier, faster and less labor-intensive to install, trusses offer additional benefits including dramatic vaulted ceilings, attractive roof lines, and even storage and attic space. Trusses also offer the peace of mind that the roof over your head was professionally engineered to withstand the forces of wind, water and snow loads that pressure your roof.

Why is a wood-trussed roof better?

Lumber used by Peninsula Truss conforms to strict local, state and national building design criteria. We cut lumber for trusses on machines that are mathematically calibrated and set to produce highly accurate cuts. This helps eliminate gaps when truss members are joined. Because our trusses are manufactured with great precision in jigs, multiples of the same truss are identical in size, assuring uniformity throughout your roof system. And, our plant is inspected quarterly by the Timber Products Inspection Bureau resulting in grade stamps which assure you that our roof systems are built to a high standard of integrity not available with conventional roof framing.

In conventional frame building, most carpenters can cut and build a roof. But, much is left to chance and the builder’s opinion. Trussed roof systems are designed by engineers or architects to fit your specific roof system and conform to applicable building codes. And, our trusses are fabricated under ideal, covered shop conditions and therefore are not subjected to a great deal of exposure to inclement weather until delivered to your site. Then, your building is closed in more rapidly with trusses, thus reducing the time that 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 drywall cracks.
