A flat roof is a surprisingly versatile structure, suitable for sheds, extensions, or even small outbuildings. This guide outlines a straightforward method to build a basic flat roof, focusing on simplicity and affordability. Before starting, always check local building codes and obtain any necessary permits. Safety is paramount; wear appropriate personal protective equipment (PPE) throughout the project.
Step 1: Planning and Materials
First, accurately measure the area the roof will cover. This determines the required lumber lengths and roofing material quantity. Framing Lumber: Typically, 2x6 or 2x8 lumber is used for the joists, depending on the span and local snow load requirements. Consult a span table to determine the correct size. Sheathing: Oriented Strand Board (OSB) or plywood (at least ½ inch thick) is commonly used for sheathing. Roofing Membrane: Modified bitumen (torch-down) or EPDM (rubber roofing) are popular choices for flat roofs. Choose one based on your budget and comfort level with installation. Fascia Boards: Lumber for the fascia, which provides a finished edge around the roof. Fasteners: Nails or screws suitable for outdoor use. Tools: Saw, drill, level, measuring tape, hammer, roofing torch (if using modified bitumen), utility knife, and safety glasses.
Step 2: Building the Frame
The frame consists of joists spanning the width of the structure. Cut the Joists: Cut the joists to the required length. The number of joists needed depends on the joist spacing (typically 16 inches on center). Attach to Walls: Secure the joists to the existing walls or support beams using appropriate fasteners. Ensure the joists are level. A slight slope (around ¼ inch per foot) is recommended for drainage; this can be achieved by varying the height of the supporting walls or using tapered insulation later. Add Blocking (Optional): Install blocking between the joists for added stability, especially for longer spans.
Step 3: Installing the Sheathing
The sheathing provides a solid surface for the roofing membrane. Cut the Sheathing: Cut the OSB or plywood sheets to fit the frame. Attach the Sheathing: Attach the sheathing to the joists using nails or screws. Ensure the sheets are staggered to create a stronger surface. Leave a small gap between the sheets for expansion and contraction.
Step 4: Applying the Roofing Membrane
This is the most crucial step for waterproofing the roof. Modified Bitumen (Torch-Down): This requires a roofing torch and careful application. Roll out the bitumen, overlapping the seams as directed by the manufacturer. Use the torch to heat the bitumen until it melts and adheres to the sheathing. This method requires extreme caution and should only be attempted by experienced individuals. Follow all safety precautions. EPDM (Rubber Roofing): This is generally easier to install. Roll out the EPDM, allowing it to relax for a period. Adhere the EPDM to the sheathing using a special adhesive. Overlap the seams and seal them with seam tape.
Step 5: Adding the Fascia
The fascia provides a finished edge and protects the roof structure. Cut the Fascia Boards: Cut the fascia boards to the required length. Attach the Fascia Boards: Attach the fascia boards to the ends of the joists, covering the edges of the sheathing and roofing membrane. Use nails or screws.
Conclusion: Enjoying Your New Flat Roof
With careful planning and execution, you can successfully build a simple DIY flat roof. Remember to prioritize safety and follow all manufacturer instructions for the roofing materials. Regular inspection and maintenance will ensure the longevity of your new roof. While this guide provides a basic framework, consider consulting with a professional for complex projects or if you lack experience with construction.
