Adding Roof Ledger To Vinyl Siding

The complexity of the job will vary with the size of roof from a simple entryway covering to one over a large screened in area.

Adding roof ledger to vinyl siding.

Unless it will be protected from rain by the house s 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. That usually is done with a header or ledger board secured to the house. I want to attach the ledger board directly into the hardiboard siding of the garage with lag screws using washers as spacers for drainage between the ledger and the siding. Next slide drip flashing behind the vinyl so the lip fits over the top of the ledger as shown at right.

To tie the roof into the siding the tin roofing panels must first be installed to. Then lag screw the ledger to the house using the fastener pattern approved in your plan. Attach your ledger board to your vinyl siding properly to have a sturdy moisture proof deck support by following these steps. A common element in adding porch roofs is fastening one end to the house either to a wall or to a roof.

The ledger board is a horizontal framing member usually two by 10 or two by 12 lumber that supports one side of a deck and attaches flat to the wall of a house after removing a section of siding. Wood or concrete siding will have to be cut away using a circular saw. Make sure you have enough room to install flashing above the ledger board and allow for at least a space above the decking preventing water from wicking upwards into wood siding. Set the blade depth so you won t cut into the house sheathing below the siding.

Install undersill trim along the edge of the vinyl over the flashing at the top and bottom. Then tack the ledger into place with 16d nails. On lean to roofs where a sloping roof plane meets the siding endwall flashing is necessary to prevent leaks.
