The Universal Roof Mount is designed to use with our #15 half round gutter hanger on angled fascias or crown molding. The roof mount is formed from heavy duty 3/16" bar stock material. The universal roof mount allows for 4.25" of total vertical pitch adjustments in 1/8" increments. Comes with 1/4" Stainless Steel bolt and locking nut.
Measuring the pitch
The pitch or the angle of a roof is calculated by how many inches it rises vertically for every 12 inches it extends horizontally. For example, a roof that rises 6 inches for every 12 inches of horizontal run is called a 6 pitch or a 6-12 pitch. If drawn on a piece of paper, this triangle would have a 26.57° angle off the horizontal line (the wall line). A different example is a 12-12 pitch, where the rise is 12" over a 12" span, creating a 45° angle. A flat roof would have a 0 pitch.
If you don't know the pitch
Its a better idea to order slightly over bent (higher pitch) then under bent. That is because although the material is not soft, it is much easier to unbend the material then to try to bend it more (unless you have a brake or hanger-bender / bar bender).
