In roof construction, it is necessary to know how to brace a gable roof in order to maintain the integrity of the structure. Security and durability are the main concerns when building a roof, regardless if it is a gable roof, hip roof, flat roof or any other type. In the case of the gable roof, having a higher pitch makes the supports more important during the construction process. At the same time, the height of the pitch makes it necessary to use a set of braces to sustain the gable ends and keep the roof in one piece, while working to mount the truss beams on the plate and on the ridge beam.
Materials and Tools
Step 1 – Safety Measures
Make sure there is another person around while working on the roof, to ensure there is help in case of accidents or falling. Also, use protection for your hands, eyes and face to avoid any injuries.
Step 1 – Attach Sloping Beams
Attach the first timber beam of the gable end of the roof by using three nails—two for the front side and one for back side of the timber beam. To ensure resistance and proper installation, use 16-penny nails.
Step 2 – Attach Sloping Beam to Roof Ridge
Use another two nails of the same type to attach the second sloping beam to the roof ridge. By connecting the sloping beams you have just attached you will obtain the pitch of your roof.
Step 3 – Strengthen the Sloping Beam
Use four studs of 1-by-6 lumber, two for each sloping beam, to temporarily strengthen your gable end. Nail them to the joist of the roof using two studs for each sloping beam, one stud on each side. This type of bracing is always useful in areas with strong winds.
Step 4 – Install the Vertical Post
Connect the point where the beams of the gable end meet with the ridge board. Use a vertical post and install it vertically, starting from the joist of the roof and going up to the meeting point of the sloping beams.
Step 5 – Attach Gable Studs
Use four vertical gable studs to add supplementary backing to the gable end, attaching them to the vertical post—two on the front side and two on the back side. By applying this strategy of strengthening the gable roofs, you fill in each gable end with gable studs and enhance the resistance level.
Step 6 – Install Braces
Install two brace studs, one of them on each end of your building. Use 2-by-6 braces, and mount each of them starting from the joist situated before the vertical post installed previously and going in a diagonal direction towards the ridge board. This will bring supplementary support to your roof.
Step 7 – Strengthen the Laterals of the Roof
Increase the lateral strength of your gable roof by attaching 1/2-inch plywood to the front of each gable end. This way, you cover every important aspect in ensuring the strength of the roof.
