Purchased home in Jan 2017 with gutter helmet already installed. Had a few issues with water runoff and icicles.
After reading the warranty and looking on line, found that the homeowner needs to keep the edges clean so that rain water will flow correctly. This was stated in their warranty. Icycles are not covered and does not affect the performance. Some damage caused by ladder being put up against the helmet.
This also is not covered. Took the piece down, straightened out the dimples caused by the ladder and is ok now. Removing a section of gutter helmet by an unauthorized installer is also grounds for voiding the warranty. Making small repairs to system where needed was important as some sections were popped up.
That also voids the warranty. That being said, I like the system very much. Reading the warranty though, too many loopholes and disclaimers. If I would have this installed brand new, which I would, I would reccomed that you find an installer that "really stands behind their work", for the items I listed above, sections popping up etc.
The warranty by the manufacturer is much to "lean" in my opinion and not valuable.
What is important is how it is installed and who does the installation. This is a great product in my opinion.
