When combined withskylightsand windows, a vaulted ceiling introduces more natural light to the home.
So, the removed pieces must be replaced in other ways.
Sistering the rafters isnt enough, so collar ties, or collar beams, must also be added.

Essentially, the collar ties perform the same function as the removed joists, but on a smaller scale.
Two gable vents on each side of the peak will also assure proper airflow and keep your roof dry.
Both projects should always be tackled by a certified professional so that the end result functions properly and safely.
Additionally, a larger HVAC system may be needed to both heat and cool the larger open space.
An HVAC professional can advise you appropriately.
Existing Chimneys
In most cases, existing chimneys don’t pose a problem when vaulting a ceiling.
Just see to it the part of the chimney that was originally housed in the attic is finished.
If it was not, you’ll need to add this expense to the overall cost of the project.
The beam is jacked into place below the roof ridge.
Each end of the beam is supported by vertical posts.
The ceiling terminates in a peaked V-shape rather than a flat ceiling.
Or lay down 1/4-inch plywood to protect the floors.
Remove all of the ceiling drywall.
Usually, this is done by making a temporary wall out of two-by-fours that rests on floor.
This wall runs the length of the roof ridge.
If the floor is above a basement or crawlspace, additional support below the floor may be needed.
In some cases, the joists are not removed entirely.
Instead, they are cut away to leave a remaining 2 or 3 feet for the perimeter ceiling.
roll out the Collar Ties
Collar ties are added to the tops of the rafters.
The temporary support system can now be removed.
This perimeter ceiling can be built from the ends of the cut joists or can be constructed from scratch.
The lights are installed.
Insulate the Ceiling
Rigid foam, sprayed foam, or fiberglassinsulationis added between the rafters.
Tip
Consult local building codes for insulation requirements.
Install and Finish the Drywall

The fully cured mud is sanded down smooth.
Paint the Drywall
A paint crew willpaint the vaulted ceiling.
They may construct a scaffold and move the scaffold around, as needed.
Or they maypaint the ceilingwith paint rollers attached to long extension poles.
When to Hire a Professional
Vaulting the ceiling is nearly always a project for ageneral contractor.
The contractor can also work with your local permitting agency and help see the permits through to successful completion.
The exposed beams sometimes required in vaulted ceilings also add character to your space, giving it arustic appeal.
Always plan on having a higher electric bill in a home with vaulted ceilings.
Vaulted ceilings are muchmore expensivethan flat ceilings, but how much more varies by design.
