Hi Everyone..I have a two year old granulated flat roof in Florida. My house is getting extremely hot inside. I have no attic for the air to flow. My central air conditioner unit is only two years old. I know it's my flat roof. My question is, can I apply a white elastomeric roof coating on my granulated flat roof without doing any damage to my new roof? In hopes of reflecting the sun light so my house will stay cooler. Thank you so much for any help.
