Flat roofs on plexes
On the Plateau, most roofs are flat roofs on duplexes and triplexes, tucked behind a brick parapet. From the sidewalk you only see the cornice, and the slate or shingle front of a false mansard.
Most leaks we trace here don’t come from the middle of the roof. They come from the edges: where the membrane turns up the parapet, around the drain, or at an old skylight or roof hatch.
We repair and replace flat roofs, rebuild parapet flashings and caps, clear and reset drains, and repair the slate fronts and sheet-metal cornices that give these streets their look.
Many boroughs now ask for a white or highly reflective membrane when a flat roof is replaced. We’ll confirm what yours requires before we quote.
No. We work from the roof and close the building up watertight at the end of every day.
If the problem is at the edges and the membrane is sound, a repair is usually enough. If it’s blistered and soft all over, it’s time for a new one. We’ll show you what we find.
Usually the drain is clogged, sits too high, or the roof has sagged around it. We clear and reset drains, and we can correct the slope when the roof is redone.
Yes. We replace broken or slipped slates by hand and redo the flashing where the mansard meets the roof and the cornice.
Often, yes. We repair or remake the sheet metal and fix the flashing above it, so water stops running into the wall behind.
