Frequently asked questions
The stain is on my ceiling but the roof above it is my neighbor's. Is that likely?
On a continuous rowhouse block, yes. The roof plane and the party wall are shared or adjoining, and water entering at one address travels along the structure before it appears. The visible damage and the actual defect are frequently in different ownerships, which is why scoping has to look past the property line.
What is a fall line and does it affect drainage?
It is where higher, harder ground drops to the coastal plain, and it does affect drainage. Water arrives with energy from above and then meets flatter tidewater with limited capacity to accept it. Properties sitting on that transition can take upstream flow while having little gradient to discharge it.
Why do flat roofs here fail at the edges rather than the middle?
Because the edges are where the movement and the water concentrate. Parapets, coping and internal drain connections expand and contract differently from the field of the roof and are also where debris collects. The membrane in the middle usually outlives the details around its perimeter.
