Despite the marketing claims that a homeowner would never have to clean their gutters again, the promises turned out to be what remained empty, not homeowner’s gutters.
Without Innovation: Every Gutter Protection System had a Major Flaw
Reverse curve gutter protection was the “new” system of the 1980s (although they were invented back in 1908). The theory was that water would flow around their curves and through a small opening into the gutter while debris would conveniently fall off. But in reality, a lot of debris would follow the water into the opening, quickly clogging the curve or the gutter. Given the expense of most reverse curve systems, that was not the result any homeowner or installer was looking for.
Sponges, the brainchild of the 1970s, gained popularity in the 1990s. This form of gutter protection filled a gutter with a porous material, were simple to install and instantly successful at keeping out debris. Most also trapped debris and hardened into a brick like object that kept water out of a gutter, too.
