We specialize in all the structural analysis, architectural layouts and drawings, and engineering stamp you need for your home renovation project.


What is the average cost of vaulted ceilings

The cost of engineering design when vaulting your ceilings depends on several key factors such as the type of existing roof and the span of the home. The fees start from

  • Site Visits by a Professional Engineer from $400+hst
  • Engineering Design for reinforcing of the roof and removal of the walls from $1200+hst
  • Architectural Drawings for building permit from $1350+hst
How long does this project take?

There are three main steps to the process:

  • Engineering Design – The typical turnaround time for engineering design once the measure-up has been completed is 8-15 business days.
  • Permit Approval – If you are applying for a building permit, the response time from the building department is mandated to be 10 business days. Given the extremely high level of renovation work in Ontario, this ranges widely from 3 weeks to 8 weeks.
  • Construction – Depending on the experience of the contractors, vaulting of a ceiling can be done in 4 weeks
Can my home have cathedral/vaulted ceilings?

The easiest way to check if you can create a vaulted ceiling (cathedral ceiling) is to determine what type of roof you have.

  • If you have a newer style truss roof, a vaulted ceiling is possible, but will require replacement of most of the framing.
  • If you have a conventional gable style roof, you should be able to vault your ceilings.
  • If your HVAC ducts are in the attic, it will be difficult to vault your ceilings, without replacing the entire system
What are the typical steps to vaulting a ceiling?

Due to the complexity of the project, the most important step is to hire a skilled framer. The general steps are:

  1. Remove the insulation in the attic & ceiling drywall
  2. Reinforce existing roof rafters and collar ties as per engineer specification
  3. Remove the existing ceiling joists
  4. Install new insulation between the roof rafters
  5. Install new drywall on the roof rafters
Is a permit needed for this?

For most vaulted ceiling projects, a building permit is required. We can provide a complete package to clients including architectural drawings for the permit application, or only work on the engineering design component, depending on your needs.

We provide both the engineering and structural know-how to transform your space.

Our team will generate architectural layouts, deliver structural analysis and beam selection, as well as acquire the required municipal permits to vault your existing ceiling.
