Quick Answer
Yes, it is possible to put beams on a vaulted ceiling. Beams can provide aesthetic appeal and can also help reinforce the structural integrity of a vaulted ceiling. Proper planning and execution are needed when installing beams on a vaulted ceiling to ensure the beams are securely attached and do not compromise the strength of the ceiling.
Explaining Vaulted Ceilings
A vaulted ceiling, also known as an arched or curved ceiling, has a ceiling that is arched or rounded up rather than flat. Vaulted ceilings create a feeling of spaciousness and openness in a room. There are several types of vaulted ceilings:
- Barrel vault: Ceiling has a continuous semicircular or pointed arch shape.
- Groin vault: Ceiling has intersecting arches that create a grid-like pattern.
- Fan vault: Ceiling has intricate radial patterns resembling an open fan.
- Dome vault: Ceiling has a circular dome shape.
Vaulted ceilings are commonly made using various materials like wood, concrete, brick or drywall. The framing requires angled rafters around the arched shape. Vaulted ceiling frames need to be properly engineered to handle the weight and forces involved.
Purpose of Adding Beams
There are a few reasons why beams may be installed on a vaulted ceiling:
- Decoration – Beams can add visual interest and architectural flair. Exposed beams contrast nicely with the angles and shapes of a vaulted ceiling.
- Reinforcement – Beams can provide extra structural support. The angled shape of a vaulted ceiling can lead to weaknesses, so beams help shore up the frame.
- Tie-ins – If the vaulted ceiling is one part of an open floor plan, beams can provide anchoring points to tie the ceiling into adjacent walls or structures.
Decorative beams are often made of wood and left exposed as an accent. Structural beams may be made of stronger materials like metal and concealed above the ceiling finish.
Considerations for Installation
When installing beams on an existing vaulted ceiling, proper planning and execution are critical:
- Inspect the ceiling structure thoroughly. Look for signs of weakness or damage that need repair.
- Determine if additional framing like sister joists or supplementary rafters need to be added to support new beams.
- Make sure the ceiling finish and insulation allow for access to install and attach the beam ends correctly.
- Account for any HVAC, electrical or plumbing that may obstruct beam installation.
- Choose beam dimensions that do not overload the ceiling but provide adequate strength.
- Allow for a small gap between the beam and ceiling for expansion and contraction of materials.
- Use metal joist hangers specifically rated for angled ceilings to tie in the beam ends.
- Secure beams with additional framing anchors placed correctly according to beam span.
- Conceal gaps with cover trim for a clean finish.
For new construction, the vaulted ceiling can be designed and framed accordingly to accommodate beams during the initial building phase.
Beam Installation Techniques
There are a few different techniques to install beams on an existing vaulted ceiling:
Sistering Rafters
Sistering involves adding new rafters next to existing ones to double up the framing. The beam can then be mounted to the new sister rafters. This helps transfer the load through the beam down into the strengthened rafters.
Supplementary Rafters
Supplementary rafters are added between existing rafters that are spread apart. This fills in the framing and creates new anchoring points for the beam.
ledger Boards
Ledger boards work as support platforms installed horizontally onto the angled rafters. The beam can then be attached to the ledger board which helps transfer the weight.
Backer Boards
Backer boards are installed flat against the vaulted ceiling surface. They provide a flat vertical surface behind the ceiling finish to mount the beam ends against.
Ceiling Access
Access holes cut into the ceiling finish allow the beam ends to be bolted directly to the rafters. Patches conceal the access points once the beam is installed.
Beam Design Considerations
The design of the beams used on a vaulted ceiling affects the installation complexity and overall visual appeal:
- Beam Dimensions – Deeper beams around 6-12″ provide more dramatic contrast. Shallower beams around 3-4″ offer subtle detailing.
- Beam Length – Full-length beams running the span of the ceiling make a bold statement. Shorter disjointed beams provide a more understated look.
- Number of Beams – 1 or 2 beams maintains a clean look. Several beams create a busy, structural appearance.
- Beam Profile – Square beams have a more rustic vibe. Beams with rounded or notched bottoms introduce interesting shapes.
- Beam Material – Wood beams have a natural, warm aesthetic. Metal beams take on an industrial, utilitarian look.
Beam Placement
Proper placement of beams on a vaulted ceiling depends on the desired appearance:
- For a symmetrical look, center beams across the peak of the arch or place equidistant across the ceiling span.
- A single off-center beam can create visual interest. Place it around 1/3 of the way across the angled ceiling.
- Align beams relative to windows, lighting or adjacent architectural details.
- Keep safety in mind when positioning beams over walkways or seating areas in case of unexpected loosening and detachment.

Conclusion
Installing beams on vaulted ceilings can provide decorative accent and reinforce the structural integrity. With careful planning and proper installation techniques, beams can be incorporated into existing vaulted ceilings or designed into new construction. The beam dimensions, layout patterns and finishes should be selected to suit the desired architectural style and visual appeal. But in general, thoughtful beam design and placement can allow you to safely add beautiful beams to enhance your vaulted ceiling.
