Building a deck over a flat roof is very similar to building a deck over a concrete patio.
Putting a deck on a flat roof.
Place the deck planks every 6 inches which will leave a small gap between each plank.
That said a lot of people subcontract the roofing work and build the deck themselves.
A roof deck is almost certainly going to be required by law to have handrails.
Step 5 add handrails.
You can use 2x material laid flat or 4x material also as sleepers.
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.
These decks are often referred to as floating as they are not secured in place as a stand alone structure.
Choose what height timber batten to use paying close attention to the height of any existing door threshold.
Prior to installing a sleeper deck the roof should be inspected by a roofing contractor to ensure that the roof is in good enough shape to allow for a deck.
The specific requirements will vary from one location to another.
Hi thanks for the interesting blog.
Nail the planks in place.
I am also planning to make a deck on my flat roof but i have some questions.
So i will not be able to put the sleepers parallel to the slope.
First you must make sure the roof is strong enough to support 55 lbs per square foot.
This requires some shimming of the deck that is typically done using foam board insulation that will not harm the roof surface.
The thing is that the roof draining is through a hole in the center of the roof.
Strips of 4 in wide epdm provide a layer of protection between the sleepers and the roof.
Either way the roofing has to be right.
Push fit easyfix shoes at gaps of 400mm down the length of timber battens 8 per m2 recommended.
They are merely placed on top of another structure.
The tiles offer more cushion than concrete and even rubber decking and they re easy to install yourself by just snapping the tiles together and cutting to fit with either a power saw or a sharp utility knife.
Plastic flat roof deck flooring for smaller flat rooftop decks with lighter furniture plastic decking tiles are a great diy rooftop deck flooring option.
You can do a floating deck and is really your only option.
Installing deck on a flat roof tips.
It s reliable it s fairly easy to work with and it requires no special tools.
If you already have one of these types of roofs you could potentially cover the existing roof with pvc vinyl decking on top of a flat hard surface but you re much better off taking the roof down and starting over with a high quality vinyl decking material.
That means there are 4 slopes leading the rain or melted snow water to the drain.
