These complains are not about GutterDome, it looks like is more about the installers.I have used different type of gutter guards and this is the best on the market.
Is GutterDome a maintenance free product?
There is no such thing as a maintenance free gutter guard. If a representative from any gutter guard company in the world makes such a claim, RUN FAST. Your gutters are the defense against extensive water damage.
Mostly, the product will self shed with the wind, but on some homes the debris might have to be easily removed from the surface.
Reason of review: Good quality.
