SlimGuard Gutter Guard consists of a high-density polypropylene mesh installed over flexible ABS plastic support struts; it’s thin enough that the two legs can be overlapped at corners. The product installs inside the gutter without caulk or screws — all you need is some sharp scissors. Because it takes up virtually no space inside the gutter, it won’t slow the flow of water in a heavy downpour. It’s available from roofing and siding suppliers for around $2.25 per linear foot.
