It takes little time to unclip the cover, roll it off, and unlock the chain/wheel locks - probably not much longer than fannying about with a garage door.
Is there a technique for removing car covers that avoids coping with unwieldy bundles of fabric and ends with a neatly stowed cover?
The cover folds up nicely and has a neat bag to store in. However, that relies on having space to lay it out and fold nicely, and takes much more time. My 'rolling' method removes it quickly, and makes recovering quick and easy too.
