I would not be with out them They do help keeping the slide cooler in the summer (not much) and a little warmer in the winter. Biggest thing is they keep the rain and snow off of the slide. Here in Mississippi They keep tons of pine straw off and acorns of. When it is raining you do not have to get out the ladder and wipe off the top of the slide just my .02 worth
