  • 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.

    • Choose a roof pitch and roof structure

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.
