I bought a Dorema porch awning and during a wet spell the top section of the awning kept filling with water. I had to keep getting up during the night and push the awning roof up to get rid of the water. I hate to think of the weight of the water in the roof section, and the strain on the awning rail. Consequently, the roof now has a permanent "sag". Needless to say, I won't be buying another Dorema.
