Vaulted/cathedral ceilings

by Howard
(Nova Scotia Canada)

We want to make our story and a half bathroom to have a vaulted ceiling. The current ceiling is 6 1/2 feet high so really not practical. The house is about 90 years old and the room is 18 feet long (running with the peek of the roof) and 13 feet wide ( running with the joists), the roof is a 12/12 pitch.

What is the best way to turn the ceiling into a vaulted ceiling?

Thank you

P.S. we are getting a carpenter to do the work, just looking to see if this is even something we should attempt before getting someone to come out to the house for a look.

Vaulted Ceiling

Hi Howard,

Thanks for getting in touch.

In order for you to change your ceiling to a vaulted one you will need to get in touch with somebody that can design/draft this up for you and ensure everything is carried out well enough structurally.
That will depend on lots of things such as the footings, walls and roof materials already in place.

If your home is brickwork I would imagine a steel ridge would need to be installed to take the weight of the gable roof and potentially the rafters doubling up or reinforcing in some other way to take the extra load when the ceiling joists and purlins are removed.

Only after the roof has been sufficiently reinforced could you go ahead and remove any of the timbers below leaving your vaulted ceiling safely above.

Then you would insulate between the rafters and plasterboard over (or inbetween if hoping to leave the rafters exposed).

I hope that helps,
