Below is some informational materials relevant to recent HOA Issues which have been discussed.
Roof Materials
It would seem the obvious answer to avoid reflective metal roofs is to ensure the metal material finish used is non-reflective coatings/colors.
Solar Panels
Some discussion suggested KRA rules prohibited roof solar arrays, but the above seems to indicate that isn’t true. My research of the KRA CC&Rs didn’t uncover restrictions regarding where solar arrays are place (ground or roof).
