How to Add a DIY Top to Your Deck

Planning and Measuring

• The first step in a do-it-yourself deck top is planning the project and taking measurements. The deck top can cover the entire deck area or only a portion of it. Some deck tops attach to the home, effectively extending its roof over the deck. Others are freestanding and independent from other structural elements of the home or deck. You may choose a seasonal deck cover that you can set up in the spring and remove before winter, sparing it from damage due to ice and snow.

Selecting Materials

• A homemade deck top can take many forms, beginning with the materials you want to use. A wooden top will likely be the best match for your existing deck, especially if you use the same type of wood. A much simpler deck top consists of a frame made from PVC piping and a fabric top that provides shade and some rain protection. Canopy kits come with fittings and tarps, allowing you to select the plastic piping and assemble the top yourself. A vinyl awning, which attaches to your home and offers partial shade, is yet another option.

Permits and Requirements

• In some localities you need a building permit to alter your deck by adding a top. Factors such as the deck's height above grade, its overall size and whether the top attaches to your home may all play roles in determining the type of permit you need. Check with your local building code office during the planning process and allow time for approval of your plans before you start a deck top building project.

Construction Process

• The construction process for your deck top will depend largely on the materials you select and the scope of the project. In general, you'll need to cut all vertical supports to length before anchoring them on or around the deck. Once this portion of the top is ready, you can attach the roof itself, either by stretching a fabric panel over the support beams or attaching roof boards and shingles one by one. Once the roof is in place, the final steps may involve painting or sealing it for protection and to enhance its appearance.
