A deck built on top of an existing roof might be a lovely addition to your home. The challenge is that it will require some form of supporting structure, as well as waterproofing and any penetrations. We’ll go through how to build a deck over an existing roof in this guide. Because installing a deck on top of an existing roof might be difficult, it’s important to do your homework before getting started. As a result, we will go over a few key points.
Professional Inspection Needed
So, if you’re considering installing a roof deck on an old flat roof, be sure it’s been professionally assessed before you start. The roof you intend to build a deck on must be capable of supporting 55 pounds per square foot of weight. It’s usually preferable to consult an engineer if you’re unsure.
A professional builder would typically do this by erecting two columns – one at each end – beneath the new deck and laying beams across the top. If you’re doing this on your own, you’ll need to figure out how to support these columns with post-tension cables or pier blocks.
Then you will need a platform made of right-angled planks that can support the weight of your deck, as well as enough space between each board for water to run off and a layer of insulation.
To avoid water infiltration, a water-tight EPDM rubber membrane should be put on top of the roof deck. Before dealing with the decking, make sure you’ve installed “sleepers,” or flat 2x6s laid flat on the roof. This will provide you a flat platform on which to install the decking.
Adding a deck to your existing roof expands your living area and provides a great place for family get-togethers and barbecues. It not only boosts the value of your property but also expands your outdoor living space, allowing you to enjoy your deck for three to four seasons, depending on where you live. A roofed deck allows you to enjoy an outdoor lifestyle away from the elements when the sun is blazing down relentlessly or the rain is driving you in from the yard.
