One part of our house has a gutter nearly 30' above grade (a dry-laid brick patio outside a walkout basement), which never gets cleaned out because I don't enjoy being on a ladder that high, and that part of the roof is not accessible from the other side (it's a non-traditional contemporary house). Luckily, because of the height, this takes several years to clog completely with leaves, but it's now time to do something agin.
I'm considering Rainhandler "gutters" to replace the traditional gutter on this section. It's about a 28' run, and drains approximately 12' of roof (it's a shed roof Lthat butts into a wall). The eave is about 16" deep.
What should I consider before making this decision?
