Flatbush covers a very wide range of housing, and the right assessment starts with establishing which part of it you are in. Victorian Flatbush, through Ditmas Park, Prospect Park South and Midwood proper, has large detached wood frame houses from the 1900s and 1910s with deep porches, complex rooflines and in many cases original slate. Those are specialist roofs, and a contractor treating them like a standard row house roof does real damage.
Much of the rest is attached and semi detached brick from the 1920s and 1930s with flat or low slope main roofs and parapet walls, plus a significant stock of pre war apartment buildings along the main corridors. On those the failures cluster at the parapet, at roof to wall transitions and at drains rather than in the field of the membrane.
On the Victorian houses the recurring problem is complexity. Multiple valleys, dormers, turrets and porch roofs mean far more flashing than a simple roof of the same area, and flashing is where water gets in. Slate itself commonly outlasts the fasteners and the flashing around it, so a slate roof that looks finished is very often a flashing and nail job rather than a replacement.
On the brick stock the parapet is the first thing we look at. Cracked coping lets water straight into the wall, where it runs down inside and appears on a ceiling two floors below, nowhere near the entry point. We treat coping, joints and the roof to wall transition as one detail rather than three small repairs.
The Victorian blocks have driveways and yards, so material stages on site and we can run a full crew. The attached blocks are the usual situation: hand carried material, dumpster permits, and scaffolding that may need a neighbor's agreement. On apartment buildings we issue a certificate of insurance naming the building and managing agent before anyone arrives and book service access in advance.
Yes, and they need a different approach from a standard row house roof. Multiple valleys, dormers, turrets and porch roofs mean far more flashing than the roof area suggests, and flashing is where the water gets in. Where there is original slate we repair rather than replace wherever the slate itself is sound.
Usually not. Slate commonly outlasts the nails and the flashing around it by decades, so a slate roof that looks finished is very often a flashing and fastener job rather than a replacement. We assess the slate itself separately from the metal and the nails, because the difference in cost between those two answers is very large.
On the attached brick stock in Flatbush it is usually the parapet rather than the roof. Cracked coping on top of the parapet wall lets water into the masonry, where it runs down inside and surfaces two floors below, well away from the entry point. A roof replacement that did not address the coping will not stop it.
Flat roof replacement runs $9 to $18 per square foot including tear off and new insulation. Shingle work runs $4.50 to $8 per square foot installed. Slate repair is quoted per job because it depends entirely on how much of the slate is sound. Victorian houses with complex rooflines sit above the simple per square foot figure because of the flashing involved.
