Oak Porch Installation
Each project is different and therefore, the following advice is subject to change depending on your individual circumstances.
Your oak porch is manufactured and built in the workshop before despatch. There are normally 4 main components and installed in order.
1. The 2 Side Returns
Whether you have chosen 2 or 4 uprights, these are pre-jointed to the horizontal (or ‘return’ beam) with traditional mortise and tenon joints and dowelled with kiln dried oak pegs. These side returns are a 2 to 3 man lift to get in to place. When in place, secure frame fixing bolts should be used to attach these uprights to your property. These are normally placed through the face of the back leg by drilling a 19mm pilot hole (drill bit supplied). The head of the frame fixing is then hidden with an oak dowel (supplied)
Your oak brackets are then located in to the uprights and secured with oak dowels. The other end of the bracket is used to locate the base of the truss. See below.
3. The Main Truss
Again, the truss is fully jointed and ready to place on top of the Side Returns. This will need lifting equipment or sufficient people on site to handle this. An alternative would be to have the components making the truss as individual pieces. The advantage is that they are easier to lift in to position. The disadvantages are that more time and skill are needed to assemble it in place.
The truss is held in place with galvanised coach bolts (supplied) screwed at an angle in to the top of the side supports. Underneath the truss will be location slots for the opposite end of the supported oak brackets.
4. Roof Components
The roof components of your oak porch consist of a ridge board and common rafters. The ridge board is designed to sit from the top of the truss back to the wall of your home. The common rafters are all pre-cut and angled ready to screw into place. The top of the rafter through into the ridge and the base into the top of the side supports.
