Flat Roofing
A flat roof is rarely dead level, because a slight fall toward a drain or an edge is what carries rain away; every low spot on the surface gets noticed by water sooner than by people.
Plenty of Pittsburgh homes carry a flat stretch over a rear kitchen, a sunroom or a porch, and water behaves there as it does on any large roof; a roofer should look at the flat parts as carefully as the pitched ones.
