How to Control Roof Moss With Copper Strips
- 1). Cut sheet copper into four long strips using tin snips. Make each copper strip 8 inches wide and 10 feet long.
- 2). Slide a putty knife underneath the row of shingles directly below the roof's ridge. Loosen the shingles' self-sealing tabs to make room for the copper strips.
- 3). Insert a copper strip underneath the row of shingles directly below the roof's ridge. Push the strip back until it touches the roofing nails attached to the shingles. Make sure at least 2 inches of the copper strip is exposed on the roof.
- 4). Hammer a copper roofing nail through the strip and into the roof every 4 feet. Install the nails an inch from the back of the copper strip, so that shingles cover the nails.
- 5). Align another copper strip next to the first one. Install the second strip using the same method as for the first strip.
- 6). Work lengthwise across the roof installing copper strips on both sides of the roof's ridge. You may need to cut more copper strips depending on the roof's size.
