Roof Trusses & Pitch Changes

Designed to Carry Loads Such as Wind, Snow, Ceilings and the Weight of the Roof.

Trusses are a key structural component and most building jurisdictions will require that they meet design loads.

They also play a role in the function of your building as well as its overall appearance. Trusses include Common; also called Standard Gable, Scissor (cathedral ceilings), Mono, Gambrel, Loafing Shed, Attic (lofts), Dual pitch, and Monument style trusses.

Sizes of trusses range from 4 to 100 feet in length. All trusses are engineered to the appropriate snow and wind loading, as well as top and bottom cord, live and dead loading. We regularly provide trusses for 35+ pound 
snow loads and 120 mph wind loads.

Roof Pitch Adds Beauty to a Pole Building

Roof Pitch, commonly known as “slope”, is defined by how many inches the roof rises across 12 horizontal inches.

Also known as Rise over Run or Rise/Run. For an example a 8/12 pitch roof means that the roof rises 8” for every 12” it runs. Roof pitch can impact both the form and function of your pole building. Most standard sized pole buildings look and perform best with a 4/12 pitch.
A roof’s pitch also serves an important function. A high pitch allows snow and water to roll off better than a lower pitched roof. A roof needs to be designed and engineered to handle snow loads in the area where it is being built.

A roof with a low pitch looks flatter, and a roof with a higher pitch looks steeper. Some homeowner associations require that a pole building have the same pitch as the primary residence.

It is also important to know that if you want additional storage space or an upstairs loft, a steeper roof pitch will be required. If you are looking for light storage, heavy storage for a second room then your roof pitch should not be lower than 6/12. If you want to have walking room in your loft where most folks will be able to stand upright and have ample walking room, we recommend 8/12 and above.
