Barbara Goldman is no garden-variety environmentalist. When she rehabbed her luxury ocean-front Marblehead home recently, she insisted that it be eco-sensitive from the basement to the rooftop.
That's not an easy assignment when green supplies typically cost more and can be harder to find. But Goldman was not deterred.
For starters, her roof is made of recycled rubber.
