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.
A roof deck is almost certainly going to be required by law to have handrails.
The deck frame is assembled so that the deck surface is level.
Step 5 add handrails.
I am also planning to make a deck on my flat roof but i have some questions.
They are merely placed on top of another structure.
Hi thanks for the interesting blog.
That said a lot of people subcontract the roofing work and build the deck themselves.
That means there are 4 slopes leading the rain or melted snow water to the drain.
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.
First you must make sure the roof is strong enough to support 55 lbs per square foot.
You can use 2x material laid flat or 4x material also as sleepers.
Either way the roofing has to be right.
Nail the planks in place.
Choose what height timber batten to use paying close attention to the height of any existing door threshold.
Push fit easyfix shoes at gaps of 400mm down the length of timber battens 8 per m2 recommended.
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.
It s reliable it s fairly easy to work with and it requires no special tools.
The specific requirements will vary from one location to another.
Install the 14 inch pieces as braces throughout the joists with a staggered row extending across the center of the deck.
Installing deck on a flat roof tips.
So i will not be able to put the sleepers parallel to the slope.
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.
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.
Place the deck planks every 6 inches which will leave a small gap between each plank.
These decks are often referred to as floating as they are not secured in place as a stand alone structure.
This requires some shimming of the deck that is typically done using foam board insulation that will not harm the roof surface.
Plastic flat roof deck flooring for smaller flat rooftop decks with lighter furniture plastic decking tiles are a great diy rooftop deck flooring option.
Framing the roof place the sleepers.
