We had Sierra Seamless Gutter Company install new gutters with Gutterglove Ultra covers and they work great. A few years later we added a deck on one side of the house and had Sierra install new gutters and Gutterglove Ninja covers on that area as well. They've all worked great and have withstood the test of time. They make the gutters maintenance free and the older we get the less we are on the roof the better. Great product!
