Most residential awnings are not truly waterproof, in the strictest sense of the word. Metal awnings can provide shelter from rain and snow, but they may be susceptible to corrosion. Canvas awnings can become saturated with water and susceptible to mold and mildew.

Is awning good for rain?

Retractable awnings will provide shade and protection from UV rays; some will even act as rain awnings too. However, most awnings that retract won’t stand up to heavy or torrential rains or snow loads.

How do I waterproof my awning?

Applying the waterproof solution Our favorite method of applying the waterproofing solution is through a spray bottle on the mist setting. We normally do three coats allowing each one to dry for 4 hours. This makes it a great weekend project as it only takes about 15 minutes to spray a 6’x8′ awning.
