Cost
Aluminum and vinyl are two of the more popular patio awnings available. But because of the process required to mold thick aluminum into a reliable patio cover, aluminum awnings tend to be more expensive than vinyl, according to Solara, an adjustable patio cover manufacturer. Aluminum patio covers require strong foundations and additional installation expenses that make the installation costs of an aluminum awning more expensive as well.
Convenience
A vinyl awning can be installed as retractable, which extends the life of the awning by getting it out of the sun and elements. A retractable awning also allows you to enjoy things such as a sunrise or sunset without an obstructed view. An aluminum awning cannot be retracted and is left exposed to the sun and elements. An aluminum awning requires periodic cleaning and repainting.
High Winds
When an aluminum awning is exposed to high winds and stormy weather, the aluminum panels act like wind sails and can be ripped off in extreme winds. The dislodged panels can become a potential danger to your home and anything in your yard during a storm.
Noise
An aluminum patio cover can be the source of noises that vinyl awnings will not cause. The creaking and banging noise of an aluminum patio cover in a light wind storm can be persistent. Aluminum amplifies rain drops, tree debris, small animals running and anything else that makes a noise when it impacts the awning.
