How does a wall-mounted gazebo like the Sojag Pompano attach to the house?

The Pompano is a wall-mounted (mural) gazebo: the back edge of the roof is fixed to your exterior wall and the front is carried by two aluminum posts anchored to a deck, patio or concrete pad. Check that the wall section is solid framing or masonry able to carry the roof load, and leave clearance above doors and windows. Anchoring hardware for the wall varies with the wall type and is not always included.
