Compatibility Information
GutterFlow is precision cut in different sizes to fit virtually all of the gutter styles and sizes common in the Pacific Northwest. Being an insert versus a cover or cap, GutterFlow installs under any existing gutter spikes.
GutterFlow is compatible with roofs of all pitches. Since it does not require any attachment to the rooftop or under the shingles, it is also compatible with all roofing materials. Finally, being impenetrable, GutterFlow is appropriate for all environmental settings regardless of whether the trees are predominately deciduous, evergreen or a combination.
