Yes, on many patio awnings the pitch can be adjusted so that the awning suits the position of the sun, the mounting height and the patio. How the adjustment is made and the range available depend on the model. On some, the pitch is set during installation; on others, it can be changed later.
A steeper angle provides better protection when the sun is low and helps rainwater run off the fabric. A flatter angle provides more clearance under the front edge of the awning. Determine the angle along with the mounting height and projection so that the awning does not end up too low. Follow the instructions for your model to ensure that both arms are adjusted equally.
