We Had leaf filter installed on our gutters 6 years ago and now the installation screws are rusty and staining our white gutters. I emailed the LEAF FILTER company website and said that the mesh screen is stainless steel but the rusty screws I thought should have been aluminum or stainless in the northern part of the country.
Leaf filter rep did contact me later called after I emailed them and said they are steel painted screws and nothing they could do.
He said not cost effective to use aluminum. I used to praise them at the home shows, but not anymore!!
