GUTTER HANGER SELECTION
In deciding which hanger style is most acceptable, please consider such things as appearance, expected life, ice loading, size of a gutter or gutters, material and expansion. When fascia board is less than 2" thick, the hanger fasteners must be driven into the rafter ends.
In areas subject to snow slide, coordinate the front edge elevation of the gutter or gutters with the extended roof line.
Gutter hangers should be spaced at a maximum of 36" on center. In areas where ice and snow are long lasting, hanger spacing should be reduced to 18" on center.
