Brownstone Roofing explained
Most brownstones have a nearly flat roof sloped to a rear or interior drain, a front parapet, and a decorative cornice that often hides built-in gutters. Water problems usually start at the transitions: the roof-to-parapet flashing, the cornice gutter, and cracked coping. Restoration means repairing the pieces together, not just recoating the roof. It may include a new roof membrane, rebuilt flashings, repointing, coping and cornice repair, and restored drainage. Landmark districts may add review requirements for visible exterior work.
Options and materials
Flat roof membrane replacement
A new modified bitumen, EPDM or similar system with proper tapered slope, drains and raised flashings suited to a rowhouse roof and its narrow, tightly built-in footprint.
Parapet and coping repair
Repointing, rebuilding failed masonry, resetting or replacing coping stones, and flashing the top, so that water stops getting into the wall and traveling down through it.
Cornice restoration
Repairing or rebuilding the front cornice, including its built-in gutter lining and supports, and matching the original profile where possible to preserve the look of the facade.
Built-in gutter relining
Relining or replacing box gutters hidden in the cornice, which are a leading cause of leaks and facade staining on older buildings when the lining wears through.
Rear and extension roofs
Replacing lower rear roofs and bulkheads that tie into the main roof and masonry, with continuous flashing so the whole roof works as one connected waterproof system.
Our process
- Whole-roof inspectionWe inspect the roof, parapets, cornice, gutters and drains together, since a leak showing up in one place often traces back to a problem in another.
- Written restoration scopeYou receive a clear scope that separates urgent work from items that can be scheduled later, with options for the roof system and for the masonry repairs.
- Approvals and coordinationWe tell you what filings or landmarks review may apply, and coordinate with your co-op board or neighbors where roofs, walls or access are shared.
- Masonry and cornice repairParapet, coping and cornice repairs are done first, so the new roof can be flashed to sound surfaces and the whole assembly lasts as long as possible.
- Roof system and flashingThe membrane is installed with tapered insulation as needed, new drains or gutter liners are set, and flashings are carried up the parapet and sealed at the top.
- Inspection and warrantyWe check every detail, clean up, and provide photos and a written warranty. A full roof replacement carries our 10-year warranty, as spelled out in your paperwork.
What affects the price
Roof area and layout
Narrow brownstone roofs are small, but extensions, bulkheads and multiple levels add detail work that raises the cost compared with a simple single-level roof.
Parapet and cornice condition
Extensive masonry or cornice repair adds scope. Often the full extent is only visible once the work is opened up, and we explain any changes in writing.
Roof system chosen
Different membranes and insulation configurations vary in material cost and installation approach, as well as in how long they are expected to perform on this kind of roof.
Matching historic details
Reproducing cornice profiles or matching period materials requires fabrication time and skilled labor, which adds to the cost of the restoration work involved.
Access and staging
Tall narrow buildings with no side access need hoisting and careful material handling through interiors or from the street, adding time and protection requirements.
Approvals and shared conditions
Work in a landmark district or on a shared party wall can add review steps and coordination time, which we plan for in the schedule.
Getting a price
Because these factors change from roof to roof, we don't publish one-size-fits-all prices. We inspect your roof for free and give you a written, itemized estimate before any work starts.
