Sloped Roofs Less Than 10/12 Pitch Installation Instructions

Install just before heavy snowfall or severe freezing winter weather.

  1. Place bricks as shown in illustration, 3-4 rows above gutter. If bricks slide when released, the roof is too steep for proper installation. Bricks cannot be installed onto roofs with a pitch steeper/greater than 10/12 pitch.
  2. Install 4-8 ft. apart. In areas of persistent or heavy snowfall place bricks 2-3 ft. apart. Bricks placed in gutters will aid in water flow but will not prevent ice dams. Replace as needed. White coloring beneath brick is dried brine. It will wash away as soon as brick is removed or dissolved.

Flat Roof Installation Instructions

Install just before heavy snowfall or severe freezing winter weather.

  1. For very small roofs with minimal drainage, place 1-2 bricks about 1 ft. from drain. Larger roofs require stacked pairs of bricks to effectively deice larger amounts of water. Place about 1 ft. from drain or scupper opening in area where water flows. Replace bricks as needed.
