Philadelphia row home roof
I have a flat rubber roof installed 9/2015. Today, A contractor doing work on the house next door to me, told me I don’t have any ventilation on my roof. Why didn’t the roofer who installed roof tell me this or is it not needed? Can a silver coating do the same as ventilation? I live in a Philadelphia row home.
