Here’s the skinny kiddo’s.  The reverse curve system DOES NOT WORK!  I’ve been a gutter installer for six years now, the last three have been working with leaf protection systems, in particular, K-Guard and Leaf Slugger.

Since November of 2006 I have subcontracted all of the warranty/service work for a couple of the big leaf protection devils… er, dealers…yeah, dealers.  In less than a year, I have been to over 600 houses to service protected gutter systems… mostly K-Guard but also topper systems that install on existing ogee style gutters.  They all clog!

Yes Joe, K-Guard does let in debris, but it does not flush them out!  Have you ever taken the time to watch a gutter drain?  There is nowhere near enough velocity in the water to flush the gutter.  There is not enough room on a facia board to pitch a gutter enough to push debris out, most of it settles on the bottom of the gutter around the downspout outlet, starting the clogging process.

Most of the companies that sell these products are a bunch of crooks!  They are companies owned and operated by SALESMAN, NOT TRADESMEN!  They sell their systems for upwards of $40+ a foot!  They justify it with a bogus lifetime warranty. All they are doing is selling a lifetime cleanout contract.  Yeah, they will clean your gutters… when they feel like it!

Oh Yeah, reverse curve systems overshoot in a moderate heavy rain and do not work well on metal roofs or steep roofs.  I have tested several systems out there and there is only one style that works… stainless steel micro-mesh systems.  There are only four companies that I know of that produce these systems… they are Leaf Solution, Leaf Filter, Gutter Glove and Mastershield.

Leaf Solution, in my opinion has the smartest design.  The one thing that these companies have in common is that they will all refund your money if your gutters ever clog.  If these systems are installed properly, they will not clog.  You can pile leaves and debris on top of them and they still take in all of the water.  Take it from me, I have seen it all and tested it all, my mind really is in the gutter… week in and week out.
