So you are considering a clog free gutter system. Congratulations and do your homework before making the investment.
Tricky thing about clog free gutters: Lots of systems are available to keep the leaves out of the gutters, but most of those systems have design flaws that don't show up until years later (usually in the form of rotted wood and roof issues). Get a clog free system designed to handle the leaves, and protect your home from water damage.
You should know that a
well-designed gutter system requires self-cleaning technology; this enables the maintenance free guttering to perform optimally long term.
You should be cautious of any system whose basic function is limited to top filtration like screens, or any hoods that rely on holes or slots; they will soon fail when debris quickly fills all the holes and prevents any water from entering the gutter. These systems are NOT maintenance free.
Beware of the outdated one-piece designs. Guard yourself from potential wood rot and gutter overflow. Take the time to Google search the problems associated with them including clogging and overflow issues.
Did you realize clog free systems must mount to your fascia board behind the roof drip edge. Never should they require any alterations to the existing roof like mounting under the shingles or installing any additional flashing/drip edge as either may void your roof’s manufacturer and installation warranties.
