This could get interesting! Welcome Gutter Helmet. My house has/had [some removed] the old aluminum screens. From past experience, & now, Pen Oaks, Love these. If the leaves aren't stuck in them, the green wormy pollen, covers them. Best of all, with or with out covers/screens/guards/ect , my clog, is Always at the opening of the down spots! I had one company give me a quote, once. The other guys! Salesman, thought he was still selling used cars! Started with an outrageous price, & when I wouldn't bite, kept calling the Manager, to get a better deal, & discounts. By the time I got him to leave, he was down to 1/2 price! It was Still too much, & I wasn't going to deal with a car salesman! All these products seem to work the same, & each one has "the Best" advantage. Between what I've seen, & what owners have told me, None are Good. Fair, maybe. They overshoot the water, in hard rain, & still get small leaves, & pollen, inside, which creates clogs. I've had some advice, to switch to commercial gutters & downspouts. These are usually 4",instead of the 3" home style, & the down spouts, are funnel shaped, & resist clogging. I haven't checked this out. SO, Let the opinions Flow!
