Why are trusses priced
as a package and not individually?
In order to price a truss, design, production
and delivery costs are calculated. When only one
truss of the same span and profile is required,
the price includes the total of those expenses.
When multiple trusses of the same design are required,
those expenses are divided among them with only
the cost of materials remaining the same.
Why do you need a project location to
calculate a price?
Aside from the logistical considerations of access
to site and delivery, there is also the matter
of snow fall. For any given area, a snow load
has been calculated consisting of the weight of
the snow which is expected to accumulate on a
roof during the winter season. The structure must
be designed to support that extra weight. These
loads are widely varied from one area to another.
What are farm trusses?
The designation or use of a building can make
a difference in how roof trusses are designed.
For instance, trusses used to build a barn roof
are often referred to as farm trusses and are
designed differently than those for the house
that is beside it. These requirements are set
out in the Building Code and/or by the local authorities.

• Maximum clear span of 40’ –
however, a truss can have a total length in excess
of 40’ with interior supports
• Building area of less than 6000 square
• Building Height of 3 storeys or less
• Maximum truss spacing of 2’ on centre
Low Human Occupancy
• Occupancy of no greater than one person
per 500 square feet
• Placement is generally 4’ on centre
Part 4 NBCC
• Used in all instances where residential
and small buildings or low human occupancy farm
situations do not apply.
Why use a ‘raised-heel’?
Raising the heel of a truss may be desired or
required for numerous reasons. On a standard truss
(with a standard heel) the overhang and soffit
will cover a portion of the wall. Raising the
heel of a truss can reduce or entirely eliminate
this overlap, allowing for exterior architectural
details such as key-stones, arched or floor to
ceiling windows. The heel may also be raised for
interior details such as increasing vault or tray
heights or even to allow for an increased amount
of insulation in the attic space.
What will my delivery
The cost of delivery has been included in the
package price provided unless otherwise noted.
In certain cases, a customer may wish to pick-up
their trusses or there may be accessibility issues
with the construction site. If this is the case
there will be a notation on the quotation sheet
that the cost of delivery has not been included.
