Under Shingle Method:
When installing, carefully lift the shingle and slide the back edge of the gutter guard under while screwing the front edge of the gutter guard to the top front edge of the gutter.
In Gutter Methods:
Optional install methods can be used when installing under the shingle is not an option. If the roof is steeply pitched or if you have a low hanging gutter, it is recommended to drop the slope of the gutter guard to between 5 and 10 degrees and install the guard within the gutter. Measure and mark the gutters to determine how much you will need to trim off the back edge of the gutter guard to fit the width of the gutter.
There are two options for in-gutter installations:
Option one is to secure 4 screws in the back of the gutter and into the fascia board allowing the back edge of each piece of Gutterglove Pro to rest atop the screws.
Option two is to slide the back edge of each piece of Gutterglove Pro into a Channel which is secured to the back of the gutter and into the fascia board.
In Gutter Methods: Can be used for Metal Roofs, Low Hanging Gutters, and when under the shingle is not an option.
