Nail through the joist hangers into the beams at the house to hold them in place. Then connect the opposite ends of the two beams at the front with a 2×10 cut to the same length as the ledger. Adjust the resulting frame until the diagonal measurements are equal.

Then brace the frame against stakes pounded into the ground to hold it square while you install the treated posts, joists and decking. Sight along the outside rim joist occasionally and adjust the length of the joists as needed to keep the front rim joist straight.

  • After that, determine the beam size youll want to use.
  • Then, choose a roof pitch and roof structure.
  • Because youre installing your roof on top of your existing roof, youll want to consider whether to remove the existing eave or keep it.
  • Next, determine how many beams, rafters, and roofing planks youll need for your design.
  • Stain your wood pieces to protect them from outdoor elements.
  • Then, fasten the post bases to the ground using lag bolts and a screwdriver and make sure they sit plumb.
  • Cut one side of the horizontal roof beam on an angle so that the rafters sit flush on it.
  • Using your nail gun, attach the horizontal beam and cut the two outer rafters to sit flush on top of the existing house roof.
  • Install the two outer rafters and attach a plain rafter beam to the very edge of the existing roof.
  • As you continue to install your rafters, cut the house end of each one so that it fits over top of the plain rafter beam.
  • Once all of the rafters are in place, attach your planks horizontally across the rafters to form your patio roof.
  • If youre covering the patio roof with shingles that match your existing roof, install black roofing felt and a layer of oriented strand board.
  • After that, you can attach your roofing shingles.

    Work from the view back, not from the house, out.

    • Calculate the sightline clearance height, about 6 feet, 2 inches, in this case.
    • Determine the beam size: 8 inches in this case.
    • Choose a roof pitch and roof structure

    This places the new roof on top of the existing roof. The next question is what to do with the existing eave under the new roof: kick it or keep it?

    To tie the design together, Peter chose to cut the rafter tails off the extend the exterior wall up to the underside of the new roof. As it turned out, the existing roof structure is a truss system, but they were able to contact the original truss manufacturer to verify that cutting the tails off would not jeopardize the structural integrity of the trusses.;

    From the we-hope-this-is-obvious desk: Never alter engineered trusses without the approval of a licensed professional engineer. Ever.
