The A-M Gutter Guard is a perforated aluminum panel that screws to the front lip of a 5-inch K-style gutter. This Old House found it effective against large debris such as oak leaves and twigs, but noted that dirt particles and pine needles can pass through the holes. Bob Vila liked that it cannot be seen from the ground and is easy to cut around brackets, and disliked that the self-tapping screws it needs are not in the box.

Waterlock Micromesh 5-Inch Gutter Guard
1 source$166.25as of Oct 11

Waterlock is a micro-mesh guard on an aluminum frame that tucks under the shingles and fastens to the front of the gutter. This Old House reports that it blocked the most debris of all the DIY brands it tested and did not bend or warp on its mock gutter. Bob Vila found that the mesh stopped everything from leaves and twigs to asphalt granules over two weeks of testing. Both outlets flag the price as the drawback.

  • — Micro-mesh stopped leaves, twigs and asphalt granules in Bob Vila's two-week test
  • — Needs only four or five screws per section, per Bob Vila

  • — Not compatible with half-round gutters, per This Old House
  • — The lip and back of the guard are visible from below, per Bob Vila
