Protect Your Home with Gutter Helmet . Keep leaves, pine needles, and other debris out of your gutters. Ensure that your home's gutters remain free-flowing. Deter rodents, birds, and mosquitoes, and help prevent other animal infestations. Stay off that shaky ladder!. Gutter Helmet has been saving homeowners time,work and trouble since 1963,when its unique gutter protection design patent was first made available to homeowners. Many imitators have since come and gone,but none of them can offer you the same protection from clogged rain gutters. That's why Gutter Helmet is recommended by Dean Johnson of Hometime and has also been featured on the PBS series This Old House.
