Design options to suit your every need

From trusses to exterior finish, UFA buildings offers a number of design options to help ensure your structure matches your vision.


All Truss Design in Alberta for farm buildings must meet the requirements of the National Farm Building Code 1995. Trusses are a more complicated issue than one might imagine. That’s because the 1995 National Farm Building Code of Canada has a loophole in its wording that allows for a significant reduction in snow load (to less than 60%!) under certain vague conditions. It’s a loophole that can lead to many potentially under-designed structures that may not be able to handle normal climactic loads, but allow any builder to say they’ve met minimum requirements for the roof system.

To that end, UFA Buildings has four hard and fast rules for the trusses we use in our projects.

1. Build for actual weather

UFA requires all farm trusses be designed to meet the current climatic data set out by the building codes of each province, not 1995 climatic loads allowed by National Farm Building Code . So whether you’re building in Alberta, British Columbia, Saskatchewan – or wherever you are – we will ensure that the truss design is built to current loadings.

2. Build for safety

We require that all trusses 4/12 slope and less, whether for farm, residential or commercial purposes, are designed for non-slippery finish. Allowing the truss designer to use slippery roof material reduction (Metal Cladding) means that snow must slide from your roof and if for any reason it does not then you must physically see that it is removed and not allow any buildup to occur.

Also requires that the roof have no obstructions such as chimneys, valleys, intersecting ridge lines, different roof slopes, snow stops or other such obstructions that will in any impede the slide of snow. This rule eliminates the need for someone to physically clear snow from any roof we build unless we are subjected to an extreme snow event.

3. Build for the future

The 1995 National Farm Building Code say that snow load design can be reduced if the building can be windswept – that is, if there are no obstructions allowing wind to blow snow clearly off the roof.

It’s a nice idea, but it fails to account for a nearby shelterbelt, for example, which can cause major drifting of blown snow, or a taller neighboring building going up in later years, or the simple fact that roofs are much wider now than they were in 1995, when the code was written. Roof must be free of any obstructions that are taller than the building roof by a distance equal to 10 times the building ridge height and wind must be fully capable of seeing that all blown snow is clearly deposited on the ground around building not another portion of the roof.

UFA requires all trusses to be constructed to “non-windswept” design.

UFA will only permit Windswept and Slippery Roof design Roof Trusses to be supplied for your building if you the customer fully understand the risk involved and accept such reductions in writing and in so doing also understand the impact on our 5 year materials and labour warranty. Buildings constructed under the Seal and Inspection of an engineer can have these reductions permitted if such reduction is stated in writing on the Building Construction Drawings.

4. Build for load

UFA Buildings ensures that all permanent roof bracing, including that not shown on truss drawings, is installed to properly transfer all loads from the roof system to the wall system and, ultimately, to the building’s foundations. We also ensure that the truss to wall system is built as required to meet the uplift loads that wind can generate on a building.
