WOW!!! I can't say enough good things about these guys. From start to finish they are the best. I started out my journey a bit skeptical do to all the things I've seen my friends try that never worked. I looked at several different gutter protection products before MasterShield. MasterShield was my last bid. Jim came out and showed me the system. Jim is highly knowledgeable and very professional. I ultimately chose MasterShield because rather than sitting on top of the gutter, if follows the same pitch as my roof. Because it follows the roof pitch, any debris would be more apt to roll off rather than get trapped on top of the gutter. When the work started the guys were great. The quality of work is amazing. While they were up there they even added some additional flashings to my roof that were missing at no charge. The system has now been up for about a month. I have a really steep roof plus I have a couple big valleys that dump tons of water right on the filter. I was a little concerned the system wouldn't be able to take all the water in a heavy downpour. Well, even with all the melting snow and the tons of rain, the system worked perfect. I couldn't be happier. Finally, no more cleaning out my gutters.
