Glare from metal roof

I recently installed Galvalume off-white color roof on a backyard gazebo. The roof is great and serves the purpose, because I, being an old retired person, don't want to have any maintenance for a long period of time. Unfortunately, my neighbor has started complaining that it does create some glare in their living room at certain time of the day. They want me to take down the metal roof. Is there any paint that can be sprayed on the Galvalume that kills the sun rays reflection and glare? Does painting Galvalume cancels the manufacturer's warranty? I do not wish to take down the roof, but also wish to have a happy neighbor, but without costing me "arm and leg." Gazebo really does not have any rain or heat issues. California has very favorable laws for installing solar panels, which cause even larger glare. No shading laws also exist. Any cheap and compromise solution? Who has stronger legal case here? Thank you.

I am sorry to hear about this. Painting the roof will void any original warranty. So, does the roof have a colored (white) finish now or is it more silver in appearance? Over time the roof will build up some dirt and grime, killing any gloss or sheen.

The roof does not have a prominent white color. It is more like silver finish. On ridges, I installed galvanized steel flashing (to cover uneven joints at the ridges). The two almost match in color. Galvalume roof has periodic pattern (bumps). A manufacturer SOALACOAT from Australia claims to dull the shine. But their pair is to minimize absorption, which is not the issue for me. On the contrary, I want the solar rays to either get absorbed or diffuse (non-specularly), i.e., non-uniform reflection. So I am looking for minimizing the glare, i.e., reflection now rather than waiting for 2-3 years. Any solution?

I am not familiar with Solacoat. You could certainly just apply a quality paint system in a matte finish. I personally do not know of other options. The problem with applying anything is that it will likely void the warranty on the roof ... and it may have a shorter service life than the roof's initial finish / coating.
