Williamsburg is four different buildings pretending to be one neighborhood, and each one leaks differently. On the Northside you have converted warehouses and glass condos built after the 2005 rezoning. On the Southside you have 1800s frame houses and brick tenements that have never had a full tear off. Near the water you have amenity roofs with pavers, planters and decking sitting on top of the membrane. In East Williamsburg you have low industrial buildings with roofs the size of a city block. We do all four, and the first question we ask is which one you have, because it decides how we find the leak.
The hardest calls we get here are the roof decks. When somebody builds a pedestal paver deck or a wood platform over a membrane, water that gets through does not come out below the hole. It travels sideways under the pavers, sometimes twenty or thirty feet, and shows up in an apartment nowhere near the actual failure. Anybody who quotes you a repair on that without lifting pavers is guessing. We lift, we flood test, we find the real entry point, and then we tell you what it costs.
The other pattern we see constantly on the Northside is a building that is only eight or twelve years old and already leaking. That is not bad luck. A lot of what went up here between 2006 and 2015 was built fast, and the details that fail first are the same ones every time: the flashing at the bulkhead, the terminations around the elevator overrun, and the seams where the membrane meets a parapet that moved.
On the Southside the problem is the opposite. Frame houses on the streets off Bedford and Lee where the deck is original, the layers have piled up, and nobody has looked underneath in forty years. We work Bedford Avenue, Wythe, Kent, Metropolitan, Grand and the streets running down to the waterfront.
What we actually see in 11211 and 11249: leaks under paver decks that travel far from the entry point, failed bulkhead and elevator overrun flashing on buildings under fifteen years old, wind lifted membrane edges on the exposed waterfront blocks, and Southside frame houses carrying three layers on an original deck.

Q: There is a deck over my roof. How do you even find the leak?
A: Not by guessing from the ceiling below. Water under a paver or wood deck travels sideways, and we have traced entry points twenty and thirty feet from where the stain showed up. We lift a section of the deck, flood test in stages to isolate the area, and only then open the membrane. It takes longer than a caulk and pray repair and it is the only way you get a fix that holds.
Q: Our building is only ten years old and it already leaks. Is that normal?
A: It is common here, which is not the same as normal. A lot of the Northside stock went up quickly after the 2005 rezoning, and the same details fail first every time: flashing at the bulkhead, terminations around the elevator overrun, and the seam where the membrane meets a parapet that has moved. The field of the roof is usually fine. It is the edges and the penetrations that were rushed.
Q: We are a condo board. What do you give us to compare bids?
A: A scope written line by line, with photographs of the conditions and the areas measured, so your board and your managing agent can put three proposals side by side and see where they actually differ. Most of the bids buildings get here are a lump sum and a paragraph, which makes them impossible to compare. We can also phase the work across two budget years if the reserve is not there yet.
Q: My Southside frame house has three layers on it. Can you add one more?
A: We would not, and on most of these the code will not let you either. Three layers on an original 1800s deck is already more weight than it was built for, and it means nobody has seen the sheathing in decades. On a frame house the deck is usually where the real damage is. A tear off costs more on the day and it is the only way to find out what you are standing on.
Q: Do you work on the converted warehouse lofts?
A: Yes, and they are their own animal. Big single ply fields, heavy mechanical equipment sitting on curbs, skylight banks, and often a roof that has had four different contractors patch four different sections. We map what is up there before we price it, because on a loft roof the equipment and the curbs are usually where the money goes, not the membrane.
Q: How much does a flat roof cost in Williamsburg?
A: For a typical Southside row house or small building, a tear off and new membrane usually runs about $11,000 to $22,000 depending on size, layers and deck condition. Loft conversions, amenity decks and larger commercial roofs are priced per square with the equipment and the details counted separately, because that is where the real cost sits. We measure before we quote.
