Matte finsih coatings

I believe this is a good place to publish my question. I am on the architectural committee for our HOA. One of our committee members was told from the initial developers when she purchased her lot that "reflective" roofs (metal) are not allowed in the CCRs. Now the discussion has been opened. Are there varying degrees of reflectivity? Some of us, believe their are metal roofs that would qualify for low reflectivity, but how will we know, if homeowners that are building in our development use such materials that would qualify for low reflectivity. Is there a rating system we should be aware of? Any information that you could provide would be greatly appreciated. I also saw from a previous question about a person complaining of his neighbors new roof and the glaring sheen. This is what we wish to avoid.

Margie, we just went through this scenario with an HOA that only allowed clay or concrete tile. They asked us to build a mock up display using the charcoal grey finish and locate it in different locations, including the golf course fairway and greens, to see if reflectivity was a factor. It was not. They approved the product for our customer and now we have others that want to follow and get away from concrete tiles. I would be happy to share the information with you for your committee.
