My mother got the kind that unroll and they are terrible. The problem is water runoff is not just water. It is bits of debris along with soot from your roof, basically the same junk that gets in your gutters. This sludge instantly clogs those roll out types and prevents them from rolling back

. And because they are made of a collapable material the stuff and moisure inside makes them stick together and what needs to be flushed away ends up getting clogged and creates a backup and pooor draninage from your gutters. To make them work properly you need to constantly clean them out. I vote no. too much work for me!
