Awnings can last a long time. The benefits of having an awning far exceed the costs involved. Frames can last as much as 10 to 15 years. The lifespan of awning covers depends on care, material, location, and usage. Annual cleaning, removal of water puddles to prevent stretching of the material, and retraction when not used help them last longer. Replacement covers can be purchased. Special tools and washes are not required. Polyester and vinyl covers are easily cleaned with soap and water.
