A shed ceiling in a home is one-half of a vaulted ceiling. The identify comes from lean-to sheds which can be added onto taller buildings. The roof solely slopes a technique. Shed ceilings are sometimes present in attic areas transformed into dwelling areas.
They’re also referred to as a lean-to, catslide, outshot, skillion, or pent ceiling/roof. (Skillion is a time period utilized in Australia and New Zealand.) Shed ceilings usually comply with the roof strains.
Shed Ceiling Development
Lean-to-style roof building comes first. Then the ceiling needs to be completed. The best ending technique is to insulate and drywall the roof rafters. Shed ceilings are very versatile.

The primary photograph reveals a 4/12 ceiling pitch. In a 12’ broad room, the excessive facet might be 4’ increased than the low facet. The second photograph is of two/12 roof pitches. Which means that the excessive facet might be 2’ increased than the low facet in a 12’ broad room.
Mono Truss Shed Ceilings
Some shed ceilings don’t mirror the roof pitch. The roof is constructed utilizing a mono truss sitting on the surface wall. Contained in the ceiling might be flat. It may be completed the identical means another flat typical ceiling is.
Scissor Truss Shed Ceilings
Many shed ceiling seems are achieved by utilizing scissor trusses. One half of the truss is a traditional flat ceiling design. The opposite half creates a vault inside the home. Inside slopes and exterior slopes don’t match. (Inside has a decrease slope.)
Scissor trusses permit for regular constructing envelope building. Vapor barrier, blow-in or batt insulation, and vented air area all through the whole attic. Truss-designed vaults or shed ceilings are deep sufficient to simply accept rather more insulation than rafter-built shed ceilings–making for hotter houses. Inside truss slopes larger than 4/12 will not be appropriate for blow-in insulation.
Shed Ceiling Concepts
From drywall to wooden to glass, shed ceilings present a number of ending choices. Aside from structural issues, any kind of end is an effective one–if the homeowners prefer it.
Listed below are a couple of of the most well-liked.
Glass Shed Ceilings
Sunrooms and home additions usually use shed roofs and ceilings. Many sunrooms have all, or partial glass roofs to make for mild and ethereal areas. Many additions comparable to extensions of kitchens or bedrooms are designed with glass within the shed roof.
Within the image under, kitchen cabinets line the surface wall stopping any window installations in that location. The all-glass shed roof turns the area right into a cheerful lighted space.
Uncovered Beam Shed Ceilings
Shed ceiling trusses or rafters will virtually all the time run perpendicular to the home and room under. The lengthy wall will run parallel to the home. Because of this most uncovered beam ceilings on lean-to roofs might be ornamental. Fake beams are product of reclaimed wooden, purpose-manufactured wooden, and even extruded polystyrene of fiberglass.
No matter performance, heavy uncovered beams present a basic or rustic feel and look to rooms. Having skylights within the ceiling provides an additional contact of curiosity.
Wooden Shed Ceilings
Ending a shed ceiling with wooden will add extra versatility to your decisions. A couple of of the choices embrace:
- Tongue and Groove. Tongue and groove boards can be found in lots of species of wooden and in numerous widths and thicknesses.
- G1S Plywood. Set up Good One Aspect ½” plywood on the ceiling. Cowl the joints with 1 x 2 battens. Use a semi-gloss oil end.
- Reclaimed Barn Boards. Reclaimed boards not solely assist the surroundings however make for a really attention-grabbing ceiling end.
Shed Ceiling Insulation
Insulating shed ceilings/roofs presents a couple of difficulties. Rafter depths may be small–4” – 12’’–limiting the quantity of insulation and the ensuing R-Worth.
Air flow could be a downside. One college of thought believes that no air flow is critical. One other recommends a vented shed roof. Many shingle producers is not going to guarantee unventilated roofs.
Learn how to Insulate a Shed Ceiling
Making an attempt to vent a shed roof that meets a vertical wall virtually all the time results in leaking. Constructing aerodynamics create snow drifting and rain backing up towards the vertical wall. Any vent positioned in that space will leak–from rain or snow soften or each.
Moisture getting right into a shed ceiling soaks batt insulation making it ineffective or worse. Water can leak into the inside of the home. Framing members will rot, entice bugs, and mildew.
The next shed ceiling/roof assemblies are two of the simplest choices.
- Compact Shed Roof Meeting – Unvented
The compact roof meeting is the usual low-slope building technique. It is extremely efficient on steeper slopes as nicely. Set up roughly 2” of closed-cell spray foam insulation on the underside of the roof sheathing. Guarantee it adheres tightly to all rafters, roofing nails, and penetrations.
Fill the remainder of the rafter cavities with fiberglass batts. Set up drywall or wooden ending. All these ceilings don’t require a vapor barrier. The underside of the roof deck shouldn’t get chilly due to the spray foam.
Spray foam has an R-Worth of 5 to the inch, eliminates air leakage, creates a vapor barrier, and stops thermal bridging. Many builders and contractors will fill the whole cavity with foam and never hassle with batts. Foam is dearer than batts.
- Icehouse Shed Roof Meeting – Vented
Icehouse roof assemblies contain two layers of roof sheathing. Set up the primary layer on prime of the rafters and canopy it with a water-resistant membrane. Flash to the wall. Set up 2 x 2 on prime of and in keeping with the rafters. Add one other layer of sheathing that ends about 2” from the wall. Set up roofing and flashing.
Any water that will get beneath the flashing will simply drain out of the underside fringe of the roof. The shed ceiling wants a vapor barrier on the nice and cozy facet of the rafters and needs to be as hermetic as attainable as a result of the underside of the sheathing can get chilly. Heat moist air from under assembly chilly air will trigger condensation and moist insulation.
