Technical Questions Explained

1. Many gutter guards only come in one narrow width and depending on their front height are not
wide enough to reach the second course of shingle if need be. Most of the time installation under
the first course is preferred, but if existing gutters are too high in elevation, then you need a
cover wide enough to go under the second course of shingle. If you are installing new gutters this
question is mote.

2. Radius bend questions. The larger and smoother the radius bend, the higher the capacity to
collect water. A 5/16" radius bend is standard for most residential rafter lengths. For rafter
lengths of 30' or longer or roof areas that have a lot of water funneled onto them, larger radius
bends are required.

3. Clips can often work loose or break if poorly designed.

4. Products that are fastened or glued to roofing could either contribute to roof
leakage or ruin the roofing it they ever need be removed.

5. This question is for the "all-in-one" gutter guard that includes it's own gutter. For reference,
standard residential gutters are 5" and carry 25 sq. inches of water whereas some "all-in-one"
systems only handle 15 square inches requiring more and larger downspouts which may detract from
your home's appearance.

6. K style gutters are the general standard in the USA. If you have one of the other gutter types,
you'll want to be sure the gutter guard can be installed to it.

7. Most gutter covers can only handle a pitch of 12 on 12 (45 degrees) and are not recommended for
steeper roofs or for that matter some are not recommended for flat roofs.

8. Erase all except the type of roofing you have on your home.
