leaf guard and solid gutter cover ia an option that many of our customers and future customers are interested in . in fact many counties in our area require this if you are re roofing or doing a remodleing project and have a building permit. one type of leaf guard is known as solid gutter cover and this product works by providing a solid top and a rounded front edge so that the water rolls over the front of the cover and into the gutter and leafs and debris fall on the outside of the gutter and not in the gutter .When combined with 3x4 downspouts the chances of the gutter plugging up and over flowing are virtually zero . And this is how we are able to include a no clog guarantee with this product . One local company in our area advertizes on local radio and tv stations and this is why so many people are familiar with this type of cover .
