Shed roof trusses are a cost-effective and straightforward way to frame a shed roof, providing the necessary support and pitch. This tutorial assumes basic carpentry skills and access to necessary tools.
Materials and Tools Needed: Lumber: Typically 2x4 or 2x6 lumber, depending on the span and load requirements. Consult local building codes. Plywood gussets (optional): For added strength at joints. Construction screws or nails: Exterior grade recommended. Measuring tape Pencil Saw (circular saw or hand saw) Square Safety glasses Gloves Clamps (optional but helpful)
Step 1: Determine the Truss Dimensions First, determine the span (width) of your shed and the desired roof pitch. The pitch is the vertical rise over the horizontal run (e.g., 4/12 pitch means a 4-inch rise for every 12 inches of run). This will dictate the length of your top and bottom chords, and the height of the truss. Create a drawing or use a truss calculator to determine the exact measurements.
Step 2: Cut the Bottom Chord The bottom chord is the horizontal base of the truss. Cut the lumber to the calculated length, ensuring it's straight and free of defects. This will determine the width of your shed.
Step 3: Cut the Top Chord The top chord forms the sloped roof section. Cut two pieces of lumber to the calculated length. Remember that the length needs to account for the overhang, if any, and the angle created by the roof pitch. The angle is typically cut at both ends. Use a speed square or protractor to accurately mark the angle before cutting.
Step 4: Assemble the Truss Lay the bottom chord on a flat surface. Position the two top chord pieces onto the bottom chord, forming the triangular truss shape. Ensure the angles are aligned correctly where the top chords meet the bottom chord. The joint where the two top chords meet is the peak.
Step 5: Secure the Joints Use construction screws or nails to fasten the top chords to the bottom chord at the angled connections. Drive screws/nails at an angle for better holding power. If using plywood gussets, apply construction adhesive to both sides of the gusset and then screw or nail the gusset over the joint, overlapping both the top and bottom chords. At the peak, ensure the two top chord pieces are tightly butted together before fastening them. Using a gusset plate here provides significant strength.
Step 6: Add Webbing (Optional, but Recommended) Adding webbing, which are additional pieces of lumber running diagonally between the top and bottom chords, significantly increases the truss's strength. Determine the placement of the webbing based on the span and load. Cut the webbing pieces to the appropriate length and angle (if necessary) and secure them to the top and bottom chords using screws or nails. Gussets can also be used to reinforce webbing connections.
Step 7: Repeat for Remaining Trusses Build the remaining trusses using the first truss as a template to ensure consistent dimensions and angles. This is crucial for a structurally sound roof. Pay close attention to detail and double-check measurements.
Conclusion: Installing the Trusses Once all the trusses are built, they can be installed on the shed walls. Space the trusses according to your local building codes, typically 16 or 24 inches on center. Secure the trusses to the top plates of the shed walls using metal hurricane ties or similar connectors. Remember to consult with local building codes and consider consulting with a professional if you have any concerns about the structural integrity of your shed roof.
