Ornament, air flow and a hangout in your rooster
Step 1: Venture overview
Add authenticity to your barn2 cupola with a reside rooster!
Once I determined to construct a cupola to gown up my bland storage, I started by taking a stroll. A lot of the cupolas in my neighborhood are purely ornamental. However the actually previous ones—people who sit atop garages that have been as soon as carriage homes—have been constructed for each ornament and air flow. Within the days earlier than roof and ridge vents, a cupola was the simplest approach to ventilate a secure, barn and even a home.
Previous or new, a lot of the cupolas I noticed had some peeling paint or rotting wooden. There have been two typical hassle spots: the “saddle,” the a part of the cupola that sits immediately on the roof, and the “sill,” which rests on the saddle. To make my saddle maintenance-free, I wrapped it in aluminum flashing (Photograph 14). To keep away from issues on the sill, I beveled mine and left no flat areas the place water might stand (Photograph 1). I additionally used vinyl brick mould, quite than wooden, to body the vents.
This text will present you ways to construct and set up a cupola with these maintenance-saving options. The cupola’s construction is pretty easy, and all the size, curves and angles are offered. The curved “witch’s hat” roof might appear to be the work of a grasp carpenter, however your complete cupola is an intermediate-level undertaking. In truth, a novice with simply a little carpentry expertise can do a passable job. In any case, minor errors gained’t be seen from the bottom. However you’ll need a number of energy instruments (desk noticed, jigsaw, round noticed, drill and router) and at the least three full days to construct this cupola.
Word: A cupola mounted on a storage or shed will hold the constructing cooler in scorching climate and drier throughout damp seasons. However on your residence’s attic, a barn cupola alone doesn’t present enough air flow: By itself, it doesn’t let sufficient air escape, nor does it present a place for air to enter the attic. For efficient air flow, set up soffit vents together with roof or ridge vents.
Determine A: Cupola Particulars
Most house facilities and lumberyards carry every little thing you want to construct this cupola. Right here’s your buying listing:
- One Eight-ft. cedar Four×Four (precise measurement is Three-1/2 x Three-1/2 in.)
- Three 10-ft. cedar 2x6s
- One Eight-ft. 2×2 (1-1/2 x 1-1/2 in.)
- One Four×Eight sheet of three/Eight-in. plywood
- One Four×Eight sheet of three/Four-in. pressure-treated plywood
- 4 Eight-ft. items of brick mould. Vinyl brick mould is maintenance-free, nevertheless it holds paint poorly and is often obtainable solely in white. If you would like a totally different colour, you’ll have to use wooden brick mould.
- 4 12 x 12-in. vinyl or aluminum gable vents. The size refer to the louvered space, not the vent’s body. Our 12 x 12-in. vents measured 14-1/2 x 14-Three/Four in. Metallic vents, that are often white, could be spray painted. For a lasting paint job, calmly sand the vents with 220-grit sandpaper first.
- One bundle of shingles. Residence facilities often inventory a few widespread colours and may special-order many others.
- One 10-ft. lengthy roll of aluminum flashing. Painted flashing often comes with one aspect white, the opposite darkish brown. However you’ll be able to flippantly sand and spray paint it after it’s utilized to the saddle. The width of the flashing you want is determined by the pitch of your roof; the steeper your roof, the longer the edges of the saddle (Fig. A).
- Galvanized screws (1-1/Four, 2 and three in.), 1/2-in. self-tapping sheet metallic screws, 1-in. galvanized nails, Three/Four-in. roofing nails, development adhesive, acrylic caulk, roof cement (two tubes).

Step 2: Build the vent housing
Photograph 1: Bevel the sill and soffit items
Bevel 2x6s on a desk noticed. To chop the items that may type the sill of the barn cupola, bolt a 1×6 to the noticed’s fence (to hold the workpiece from tilting), set the blade at 19 levels and place the fence Three/Four in. from the blade. To bevel the soffit elements, set the blade at 45 levels and the fence Four-Three/Four in. from the blade. To make bevel chopping simpler, we first reduce 2x6s into 30-in. sections. When all eight items are beveled, sand them after which miter the ends at 45 levels. Save the beveled cut-offs from the sill and rip about 1/Four in. off them. You’ll use them later to full the slope of the sill (Photograph Four).
Photograph 2: Assemble the sill and soffit frames
Assemble the sill and soffit frames by screwing short-term plywood scraps to the undersides of the 2x6s. Don’t cowl up the corners—you’ll want to drive screws by means of them later. And make it possible for the sill and soffit frames are completely sq..
Photograph Three: Add the nook posts
Screw the sill to the nook posts. Drill pilot holes and drive 4 Three-in. screws into every submit, two on all sides of the miter joint. The internal edge of every publish ought to meet the within nook of the sill.
Photograph Four: Connect the brick mould frames
Assemble brick mould frames between the posts. Pre-drill and countersink the holes earlier than driving screws. You could have to draw the posts collectively or unfold them aside to make the highest piece of brick mould match. Screw the underside and sides of the frames to the posts and screw the highest piece to the edges. Keep in mind to fasten the beveled cut-offs to the sill with nails and development adhesive prior to installing the brick mould. Fig. A exhibits the small print.
Photograph 5: Add the vents to the frames
Screw the vents to the backsides of the brick mould frames with 1/2-in. self-tapping sheet metallic screws. Then connect the soffit to the nook posts simply as you hooked up the sill.
Fig. A provides all the size you’ll want to reduce the elements for the housing. Pictures 1 – 5 present the way it all goes collectively. Listed here are some pointers to assist you to alongside:
- Until you have got a sliding miter noticed, use a round noticed to miter the ends of the 2x6s that make up the sill and soffit. A round noticed isn’t the perfect device for making good miters, however small imperfections gained’t be seen from the bottom.
- We minimize coves into three corners of every Four×Four publish (Photograph Three) utilizing a 1/2-in. radius cove router bit.
- Use a couple of items of duct tape to maintain every vent in place as you drive screws by way of the vent’s body and into the brick mould. To save lots of your self the difficulty of drilling pilot holes, use self-tapping screws
- Fill the cracks within the sill and soffit and seal across the vents, brick mould and posts with acrylic latex caulk. Water that will get into the vent housing might lead to peeling paint. You can too use caulk and a putty knife to cowl the screwheads within the brick mould.
- Acrylic latex paint is one of the best end for the wooden elements. However all the time prime cedar with an oil-based primer designed to seal in “tannins,” pure chemical compounds that bleed by way of latex paint, leaving brownish stains.
Step Three: Build the ‘Witch’s Cap’ roof
Photograph 6: Reduce the curved rafters
Mark and minimize one rafter, then use it as a template to mark the opposite three. To mark the curve, we put a part of plastic door cease molding in a bar clamp and tightened the clamp till the curve was proper. Any skinny piece of wooden will work, however we used plastic as a result of it doesn’t have knots or another imperfections that lead to an inconsistent arch. Use a protractor to mark the right angles on the ends of the rafters.
Photograph 7: Fasten the rafters collectively
Be a part of the rafters utilizing a 6-1/2 in. piece of two×2 as a hub. Screw the hub to two of the rafters, and fasten the opposite two by driving Three-in. screws by way of the rafters into the hub. Middle the rafter meeting on a 26 x 26- in. piece of three/Eight-in. plywood and drive 1-1/Four in. screws from under by way of the plywood and into the decrease finish of every rafter. Minimize a gap within the plywood base so the roof can dry out if water will get in.
Photograph Eight: Screw the sheathing to the rafters
Fasten the three/Eight-in. plywood to the rafters with 1-1/Four in. screws. Start on the center, driving the screws at an angle. There ought to be a hole (about 1/2 in. vast) between the items of sheathing. When the sheathing is completed, middle the roof on the vent housing and drive 4 screws up by way of the soffit into the roof’s base. You possibly can take away the roof later to make it simpler to carry. Essential: Be certain to reduce the roof sheathing in order that the grain runs horizontally throughout each bit. Plywood bends extra simply throughout the grain than with the grain.
Photograph 9: Nail on the roof shingles
Shingle the roof starting with a “starter strip,” a full shingle nailed to the roof the wrong way up. The starter strip ought to overhang the plywood by about Three/Four in. With the starter strips in place, start nailing on the Four-in. extensive shingles. As with the plywood roof sheathing, depart a hole between the shingles on the ridges. Glue the decrease edge of every Four-in. tab down with a dab of roofing cement.
Photograph 10: Add the ridge cap
Nail the ridge cap shingles over the ridges. Lay heavy beads of roofing cement alongside each side of the ridge. To make the shingles conform to the curve of the ridge, we minimize them 5 in. lengthy. The primary shingle on every ridge have to be minimize to match the nook of the roof. The corners of the stiff shingles might rise up at first, however a few hours within the scorching solar will make them lie flat.
Photograph 11: Cap the roof with flashing
Cap the roof by folding a 9 x 14-in. piece of flashing across the peak (see Fig. A). Maintain the flashing in place when you mark it for chopping. When the cap is minimize, fold it again into its pyramid form, squeeze a giant blob of roofing cement into it, press it onto the height and drive one roofing nail by means of the aspect of the cap that has the overlapping seam.
The curved roof is probably the most time-consuming a part of this undertaking. Listed here are some ideas to make the job go easily:
- Use a jigsaw to reduce the curved rafters. Don’t fear about making the curves good. The roof sheathing will clean over bumps and dips.
- Mark the curves for the roof sheathing utilizing a piece of door cease and a bar clamp such as you did for the rafters (Photograph 6). The curve is gradual sufficient to be reduce with a round noticed set to a chopping depth of about 1/2 in.
- The gaps between the items of sheathing on the ridges (Photograph Eight) will permit the ridge cap shingles to curve gently over the ridges. Should you place the sheathing items tightly collectively, you’ll get a sharp ridge and the shingles will crack whenever you bend them.
- Minimize full-size shingles into Four-in. large strips with a utility knife, utilizing a framing sq. as a information. Every of the three tabs on a full shingle is about 12 in. extensive., so that you’ll get 9 small shingles from every full shingle.
Step Four: Customized-fit the saddle
Photograph 12: Measure the roof pitch
Assemble a roof pitch gauge by laying two boards over the ridge of your roof and screwing them collectively.
Photograph 13: Hint the reduce on the saddle
Mark two sides of the saddle utilizing your roof-pitch gauge. Place the purpose of the gauge on the middle line about Four in. from the highest of the saddle and align the legs of the gauge with the within edges of the saddle. Then reduce out the V-shaped notch that may straddle the ridge of the roof. For the saddle’s development, see Fig. A.
Photograph 14: Flash the saddle
Wrap flashing tightly across the saddle and fasten down the seam with self-tapping screws. To crease flashing round corners, use a hammer and wooden block. When the saddle is wrapped, fold down the overhanging flashing alongside the highest and backside edges. On the V-notch, reduce the flashing, fold the flaps into the saddle and safe every flap briefly with one screw. All of that is a lot simpler in case you have a helper. And ensure to put on gloves—or plan to go to the emergency room for stitches!
- Build the saddle from pressure-treated plywood, then mark two sides of the saddle with the slope of the roof utilizing your roof pitch gauge. After making the cutout, cowl the outside of the saddle with flashing.
Step 5: Screw the three elements collectively
Photograph 15: Screw the saddle to the roof
Fasten the saddle to the roof with 2×2 cleats. First lay a bead of roofing cement on the roof alongside every sloped aspect of the saddle. Then fold the 4 flaps down over the cement (reduce them again in the event that they prolong over the roof gap). Drive 2-in. screws via the 2x2s into the saddle and Three-in. screws into the roof. Seal the hole on the ridge with roofing cement and caulk across the higher fringe of the saddle. However depart the 2 low edges of the saddle unsealed so any water that will get in can drain out.
Photograph 16: Connect the vent housing to the saddle
Fasten the vent housing to the saddle by driving Three-in. screws by way of the sill into the two×2 rails contained in the saddle. Make sure the housing is centered on the saddle earlier than you drive any screws.
Photograph 17: Lastly, add the roof
Drive 2-in. screws by means of the soffit into the roof’s plywood base. Then caulk over the screwheads and contact them up with paint.
In case your roof is just too steep to comfortably stroll and stand on, you’ll need to use roof brackets (Photograph 17) and/or a security harness. And keep in mind that rooftop security additionally consists of holding away from energy strains.
In case you don’t need air flow, merely mount the saddle, as proven in Photograph 15, with out doing something to your roof. In case your barn cupola will probably be used for air flow, you’ll have to reduce a gap in your roof. The opening ought to be about 16 in. extensive on the ridge and prolong 10 to 14 in. down from the ridge, relying on the pitch of your roof.
You’ll be able to minimize the opening with a round noticed or jigsaw, however watch out to reduce solely via your roof’s sheathing and never into any of the structural lumber beneath. Chopping by means of asphalt shingles will damage a noticed blade. So both use an previous blade or first reduce away the shingles with a utility knife.
The barn cupola isn’t terribly heavy: The three elements weigh about 80 lbs. altogether. However they’re giant and clumsy. Should you’re not snug carrying them up a ladder, lease scaffolding. For a typical storage, you’ll want just one part of scaffolding. For a one-story home, you could want two sections.
As soon as the barn cupola is on the roof, all that’s left is screwing the three elements collectively, caulking and touching up the paint. Now there’s one thing to crow about!
