Can Your Deck Support A Roof
A deck alone can never support a roof. For instance, you cannot rely on your deck joists or beams to support your roof as well as your deck. Load tables for joists and beams consider 10 psf dead loads, which is the amount of lumber used on the deck alone not a deck and a roof. Therefore, adding a roofs weight onto a deck negates the structural integrity of the deck.
A deck roof will need to be supported by posts and a beam. The posts will need to be on concrete footings, deep enough to go beyond the frost line in your area. A beam will connect the posts and will be sized according to the local building code. The rafters will support the roof itself and connect the beam to the house.
If you already have appropriately sized posts supporting your deck, there is the possibility of integrating existing deck posts with the roof posts however, in most cases, the deck roof will require new footings.

Once in place, the ledger can support beams or joists that will support rafters or trusses for gable or hip roof construction.
When installing the ledger board, youll need to put flashing over the top edge of the board. This flashing should go up and under your siding. You should use an adhesive to affix it to the sheathing beneath the siding.
Youll need to bend the flashing to sit flush over the top ledger board edge. The flashing should cover the top half of the ledger board. Once the flashing is installed, the rafters will sit on top of the flashing.
