Aluminum Guy, the thirteen years experience has nothing to do with Mastershield as the product has not been around for 13 years. How long have you actually had the Mastershield? As a former dealer of Mastershield ( and that is a pretty long list) I can tell you that you know not of which you speak. Here is the whole scam behind Mastershield: Their money back warranty is impossible to ever have a claim on because it says absolutely not one thing about their filter itself clogging. They claim that they have a self cleaning filter, but when the filter itself clogs, no warranty. Their warranty is against the interior of the gutter clogging, but is is impossible. What good does that do though when no water is making it into the unclogged gutter because the Mastershield is clog. Mastershield has absolutely no warranty whatsoever against the Mastershield itself clogging. Don't take my word for it, read their warranty. Mastershield rips apart all the companies with the free cleaning warranty yet when their mastershield clogs they tell you to scrub it with a brush; nice warranty for $30.00/ft! I have seen Mastershield clog from roof oil, shingle grit, leaves, pine needles, moss, mold, lichen, snow, ice and much more but because the gutter is not clogged, you are out of luck. Some attorney general somewhere should force Mastershield to make claims that are not so tremendously misleading.
Bob Vila, do not be bullied again by Mastershield into pulling down the truth about their product. When they contact you, and you know they will just like last time someone told the truth on your fine website, don't be bullied, I would be happy to provide pictures of every one of the aforementioned conditions. It is time that people knew the truth about this overpriced scam.
By the way, I can also tell you as a former Mastershield dealer that Tim Carter is paid for his endorsement. Absolute fact. The one place on the internet that speaks highly of Mastershield gets paid for every lead he brings into Mastershield. You people who bought based on his word and are now experiencing problems should bombard askthebuilder.com and ask Tim how much he took to sell you down the river. The time has come for the Mastershield dealers and owners to stop visiting every homeowner site that caters to the honest homeowners, like this one, and posing as homeowners themselves so they can distort the truth. They should spend that time rewriting their warranty so that it actually covers their own product and not the gutter underneath it.
