Flashing A Patio Roof Ledger

How to attach a patio or verandah to a house

Unless it will be protected from rain by the houses eaves or a solid roof, a roof ledger that is fastened directly to a house with wood siding should be capped with galvanized metal Z-flashing that tucks up under siding to prevent water from seeping in behind it.

Where integral flashing isnt possible, such as on a stucco wall, use Z-flashing and caulk the top edge. This is a job you must do before fastening the overheads roof rafters in place.

You can buy L- or Z-shaped flashing or bend it yourself. To bend sheet-metal flashing, make a form by clamping two 2 by 4s together on each side of the metal, and then hammer the metal to create a sharp edge at each fold.

Fit the flashing in place, caulk the top edge, and nail it with galvanized nails long enough to penetrate at least 1 inch into the structural members. Then caulk the nail heads.

If the house is sided with shingles or lap siding, simply slip the metals top edge up under the bottom edge of the shingles or siding as far as possible.


How Do You Attach A Ledger To A House For A Patio Cover

Installing a patio cover that ties into the side of your home is a much simpler process than connecting a porch roof to the roof of your house. The rafters for the patio cover rest on the ledger board.

Heres a step-by-step guide to attaching a ledger board to your house:

  • Choose where to attach the ledger board: if you have a single-story home, attach it to the header beam just under the eaves of your roof. If you have a two-story house, attach the ledger board to the rim joist between the first and second floors.
  • Remove the siding where the ledger board will be located so you have a flat surface.
  • Attach the 2 x 6 ledger board to the rim joist or header beam using lag bolts. Where possible, bolt it into the wall studs, as well.
  • Attach washers to the lag bolts to increase their holding strength.
  • Install metal flashing along the top of the ledger board, with the top edge of the flashing under the siding just above the ledger board.
  • Carefully caulk the edges of the flashing and the nail heads.
  • Now youre ready to build your patio cover, using the ledger board as the main structural support!
  • Go To The Same Height As The Existing Roof

    If you want to have a clean look and make the patio cover flush with the existing roof, you need to strengthen the fascia and back channel by reinforcing the rafters inside the existing roof.

    Then, fix the back channel to the fascia boards underneath the gutter directly. This might be one of the common ways of attaching a patio cover to an existing home.

    It is simple and easy to do. However, by using this method, your patio cover cannot go high or low.

    Is It Acceptable To Attach Elevated Deck Joists To Rafter Tails

    I’m having an attached patio built by a contractor. I am concerned about the quality of the construction. In particular the attachment of the patio joists to the house rafters. Instead of using a ledger board, our contractor has simply attached the patio joists to the rafters using nails. Is this safe?

    • 3Reading between the lines, it sounds like you don’t have a building permit for this. If you did, the inspection would clear up this question. Please clarify, though, if this is roofed, open rafters, or floor for a second level. Aloysius DefenestrateDec 2 ’15 at 2:04
    • Is this a platform intended to support human weight? 2×6 joists at 24″ centers are not adequate, even with a ledger and steel hangers.

    If the building inspector stopped at your job he would put a stop order on it. You should have a 2×6 or 2×8 bolted to the house framing and then run your rafters or joists what every they may be from that using joist hangers.

    this doesn’t look like a patio. the patio is the area you stand on, not the roof overhead. this looks like a pergola. if it gets covered, then its a roof. either way, its not okay to build it that way

    Covering The Roof With Plywood And Shingles

    Now we have arrived at the final step, which is covering the roof. For you to know, there are two sub-steps here.

    The first is for covering all the surface of the roof frame with the first layer known as sheathing. Here we recommend you to use plywood with ½-inch thickness.

    The reason why we recommend you to choose plywood for the roof sheathing is that it has a better ability to hold moisture for quite a long time. Besides, this material is also quite strong when serving the function as roof covering.

    The second sub-step that you must do here is covering the sheathed roof with shingles by nailing these materials down to the plywood sheathing and rafters. In this case, we recommend you to choose something with the same appearance with your existing roof. The reason is none other but a coordinating look.
