Planning for the slope in which the gutter guard will be installed is an important first step. First, determine the pitch of the roof. If the roof is mildly to moderately pitched (between a 1 and 6 pitch), you can install LeafBlaster Pro at the same slope (5 to 25 degrees). If the roof is steeply pitched (7 or greater) the recommend slope of the gutter guard once installed is 5 to 10 degrees or 1 to 2 pitch. You will need to use one of the bending methods to achieve this.
