Maintenance for aluminum patio covers is as easy as a hose and some soap. Generally installed at a slight angle to aid water runoff, spraying the cover with a hose several times a year is usually all that’s needed. For more persistent dirt you simply use a push broom and some soap and it should come off easily. If the cover starts to look a bit ragged after a few years it can be repainted, but a specific process must be used.
One of the biggest concerns for aluminum patio covers is their attractiveness to birds and certain insects. The heat dispersing properties of aluminum make it a great place for birds who might build a nest in the corner where the patio cover meets the house. Debris from the nest can easily clog the gutters, creating drainage issues. Bees seem to like aluminum as well and are prone to building their nests on the underside against the house.
