How To Build A Roof Deck On A Flat Roof

One issue that many people question me about is how to create a deck that is functional without compromising the waterproof roof surface.

How to build a roof deck on a flat roof. Hi thanks for the interesting blog. Flat roofs are more susceptible to leaking than pitched roofs. Building a deck over a flat roof is very similar to building a deck over a concrete patio. Shed roofs project as a single plane roof pitched away from the house.

Inspect the roof to make sure it is in good condition and acquire any permits that may be required by the local zoning board. 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. If you are tying the roof directly to a house wall you can install a ledger board with flashing and install rafter ties to attach the rafters at the appropriate angles or use engineered trusses.

These decks are often referred to as floating as they are not secured in place as a stand alone structure. Frame up a box the size of the outer dimensions of your deck using 2 by 4 inch lumber. Flat roofs with easy access are great for creating an outdoor living space. The thing is that the roof draining is through a hole in the center of the roof.

Two people can install a brand new deck in a weekend with little or no previous construction experience. Then run joists connecting the front of your roof with the rear every two feet along the length of your roof. Before beginning however it is important to do two things. But here it s a little bit more of a challenge.

Build the frame of the roof on the ground. Now unlike your backyard that may be unlevel when you re building a deck you can set your post and adjust your framing nice and level. First you must make sure the roof is strong enough to support 55 lbs per square foot. Building a deck on a flat roof is neither difficult nor time consuming.

One of the challenges in building a deck on a roof like this that s unlevel is the deck needs to be level.
