Hi. We're re-roofing our home and will be installing new rain gutters soon. Does anyone have any opinions on the leaf guards or gutter helmet products that are meant to keep debris out of the gutters? Do they work well? We have a lot of trees in the yard and many maples that make a mess in the spring. The roofer wants $3.00 per foot extra to install the product. Is it worth it or is is something we can live without. I say no, but she says yes. If anyone has these on their gutters please let me know what your experience with this has been. Thanks. DAVE.
