After you determine the clearance height, here’s what you should do next:
- If you plan to place the additional roof on the existing roof, then you should consider whether to remove the eaves or not. If you plan to place it under the existing roof, you can skip this procedure.
- Pick and determine how many beams, roofing planks, and rafters you will need for your roof.
- If needed, you can stain your wood pieces with protective paints before installing them.
- If you plan to place a pillar on your patio roof, work on it first after considering the patio’s height. Make sure to make it perpendicular to the ground.
- Install the roofing. Starting from the joist, rafter, and later the beams and planks. Consider adding eaves while installing it.
- Now, it’s time to apply the roofing felt to protect the roof’s inner side from moisture and such.
- Lastly, shingles on top of the underlayment – the outer side of the roof is done.
- Cover the inner roof side (the ceiling’s side) with plywood, plasterboard, or anything. Apply some paint to beautify.
How to Join Two Roofs Together?

- Measure the joint area. Make sure to include the 6 inches edge into the counting.
- Prepare the flashing joint. Then, according to the size you have obtained, cut the flashing material with metal snips.
- Place the flashing material at the meeting point. Start by placing it from the higher joint area first. Remember to slip the flashing material to the roof pitch as well.
- Bend the joint with the help of lumber to make the shape suitable for the slope. Take away the lumber after you finish making the bend.
- Seal the flashing edges afterward. Prepare two pieces of 1×1 inch lumber and cut it with the length of the flashing itself. Then, slip each lumber piece under the roof pitch to align well to the roof edge. Apply a bead of sealant material along the top and bottom of the lumber piece.
- Next, secure the flashing with metal screws with 6-inch spacing between each screw.
- Make the flashing cut-edge neat. Then, cover the flashing with shingles similarly looking with the surrounding shingles.
