If a topper flaps excessively, the installer unrolled more the one complete turn off the roller when doing the assembly. I did that with the 13 footer on ours as my helper only had a very few minutes he could spend. The fix was to add that. in this case those 2 turns. Not difficult, but time consuming in that you need to remove the brackets AFTER pinning the roller. Once the brackets are loose, and one end at a time the pin is removed, the requiste number of turns are - carefully - wind the bracket against spring tension. Flapping gone in all but the worst winds. It will also help in keeping those gallons of water from pooling, but not a cure on a long awning,
