Having a roof deck on your roof is the most beautiful thing. And if you are going to build one on your pitched roof, you may want to know how to build a roof deck on a pitched roof.
Constructing a rooftop deck on your own, particularly on a pitched roof, might be difficult. But, you can do it perfectly by following the step-by-step guideline.
If you want to take the challenge of building a roof deck on your pitched roof, read the article to the end.
How To Build A Roof Deck On A Pitched Roof: Steps To Follow
Aside from the ease of walking out of your second-floor house onto your deck, the view is one of the finest reasons to install a deck. So, you can have a good time on your deck, if you build it correctly.
The construction beneath the joists on a deck with a pitched roof demands a different technique. Unlike decks on the ground level, roof deck construction does not require a ledger linked to the house’s rim joist.
Instead, a frame for the deck is created by a couple of beams resting on supports known as sill plates. Everything above the beams is the same as it is for any other deck.
We are explaining the step-by-step guideline in the rest of the article.
Gather All The Necessary Tools
Getting the appropriate materials is the first and most important step in creating a rooftop deck.
The deck framework, the support beams, and the deck material are the three most important components of a rooftop deck.
- Long-lasting lumber for the beams
- Sleepers, plastic number or wood for the deck framing
- Synthetic decking materials such as PVC or composite wood.
Obtain the required permissions and clearances
Before constructing a roof deck, be sure your area permits it. A roof deck may be prohibited in some locations or towns due to zoning restrictions and construction requirements.
Fulfill the criteria for a deck atop a pitched roof from the authority office in your region. Any unique setbacks should be communicated to your architect.
Work On Sill Plates And The Support Beams
Cut the support beams and necessary sill plates from the lumber you occupied. You’ll need about 4 pieces of 1-foot 2-by-6 timber for the sill plates.
The architect will supply specs for the support beam, although it will most likely be made from a 4-by-10 bit of timber.
Then, drill every 3 feet along the edge of the beams. And then install a galvanized lag nail on each.
At the rear face of the lumber, fasten with a washer and clamp. Use a ratchet wrench to firmly secure the nuts.
Joining The Beams With The Sill Plates
Place one beam straight on the front set of sill plates of the sloping deck. To find actual verticals, have an aide hold the beams in place using a spirit level.
Over one sill plate, add a hold-down, a sturdy metal angle bracket on each surface of the beam. Label the hole on the hold down on each sill plate. Then attach the beam aside.
To finish your roof deck’s framework, continue the cycle with a backset of sill plates and support beams.
Set The Threaded Rod
Drill trial holes with a 3/8-inch wooden drill bit through the sill plate and its wedge through your markings. Drill a small nick in the roof surface with the drill bit to mark the start of your pilot hole. Then, place a threaded rod through the holes to keep the sill plate in place.
Allow the threaded rod to cure according to the epoxy manufacturer’s recommendations. To attach the hold-downs, sill plates, and shims, screw a nut on the top of every threaded rod and secure it when the epoxy has cured. Apply this technique on every sill plate.
Installation Of Joist, Framing, And Deck Boards
Make sure all the beams are secured perfectly. Then, install the joists, framework, and deck boards according to the manufacturer’s instructions.
I think you’re ready to accept the challenge after knowing how to build a roof deck on a pitched roof. So, start to build your roof deck on your pitched roof with a proper plan.
Don’t overlook any step. Complete every step with caution. Remember that, any loose beam can create a big accident later.
Stay safe. All the best.
