How Do You Build A Deck On A Flat Roof

Then run joists connecting the front of your roof with the rear every two feet along the length of your roof.

How do you build a deck on a flat roof. However i would highly recommend that you consider a that the epdm is lying flat on the roof subfloor without any sharp objects that can puncture the edpm once sleepers are laid over top and placed under load. A deck on a sloped roof requires a different approach to the framing underneath the joists. That will make laying deck boards on top tricky as they ll run parallel to the sleepers in spots. The next step is to get a tufdek certified contractor to come and take a look at your flat roof to see if a vinyl roof deck is in your future.

If you are designing or building a flat roof at home you need to do a little more research to show you how and where to incorporate a vapour barrier into your roof and whether or not you need in the case of an externally insulated roof to add a further layer of roof decking timber to the top of the insulation. That said a lot of people subcontract the roofing work and build the deck themselves. The last thing you want to do is stop that water from flowing off the roof deck so your sleepers must run parallel to the slope of your roof which will mean setting the sleepers in a radial pattern like spokes on a wheel. Building a deck over a flat roof is very similar to building a deck over a concrete patio.

We hope you enjoy it never mind we know you will. You can use 2x material laid flat or 4x material also as sleepers. Build the frame of the roof on the ground. This will provide the surface for you to attach the decking.

It s reliable it s fairly easy to work with and it requires no special tools. Instead a pair of beams rest on supports called sill plates to create a frame for the deck. The specific requirements will vary from one location to another. A roof deck is almost certainly going to be required by law to have handrails.

Once you have your beams in place everything above them joists deck boards balusters and handrails is the same as for any other deck. When you know the requirements use 2x2 lumber for the rail posts and connect a 2x6 to their tops edgewise for the handrail. You can do a floating deck and is really your only option. Strips of 4 in wide epdm provide a layer of protection between the sleepers and the roof.

Roof deck framing unlike for decks at ground level doesn t entail a ledger attached to the rim joist of a house. Then you will install sleepers or flat 2x6s laid flat every 16 on top of the roof surface. Either way the roofing has to be right.
