Repair or replacing a flat roof on a Row House
My mother's house has a flat roof made of fiberglass paper and hot asphalt. The house is a 2 stories brick row house with a basement that's 1,120 sqft. It started to leak recently and needs to be repair.
There are now interesting roofing materials out there like EPDM rubber, PVC membrane and fiberglass. I was wondering if someone can point out the cost and life of each.
Keep in mind that she live in the Northeast where there's rain and snow, but not that much of it.
