Gutter Guard Video

I have a one-story home, walkable roof.
I installed the MasterShield product on my roof. In a heavy rain water pours over the gutter from the copper valleys. The system just cannot handle a heavy rain.

Am awaiting gutter installation solution (they have been here twice) and perhaps the manufacturer or their rep.

when you tested the micro screen types, did you evaluate minimum assembly strength.

i.e. I did that with samples of your 3 finalists and gutterglove wsa 3 times stronger than the other two - the test was to place assemblies of each across supports and load them with small sand bags adding one each 24 hours. gutterguard being stronger and with higher grade stainless screen. How did you grade mastershield higher????

What's the mfg. of the black plastic gutter gaurd you displayed at the end of your video? how does it hold from the hot sun?

what's the mfg. of the black plastic gutter guard you dispayed at the end of your video?how long was this tested?

Like many others here, I would like to know what the manufacturer of the black plastic mesh you show at the end of this video is and where I can purchase it. Did it tend to clog over time? Thank you.

Where do I fine the plastic gutter guard shown above.
