Lifestyle awnings have their own internal box gutter system which collects the patio roof/awning’s water and it is drained by a downpipe that is placed where a slight fall has been created (you get to choose before installation where you want the down pipe to be situated, then a slight fall is created to that point). In some installations, more than one downpipe will be required (The size of the patio roof & if it is patio ceiling roof will determine the number of downpipes required).
The Lifestyle Awning system is designed to handle its own rainwater runoff, but not additional load that may fall (perhaps from some height and at some speed) from the house roof.
