Brooklyn House Types: A Homeowner's Guide to Building Styles and Roofing Needs

Brooklyn is one of the most architecturally diverse boroughs in New York City. Its housing stock tells the story of two centuries of development -- from Federal-style row houses to modern condo buildings. For homeowners, understanding your building type is the first step to maintaining your roof properly.

Each Brooklyn house type has specific roofing needs, common problems, and maintenance requirements. Here is what you need to know.

Brownstones

Brownstones are Brooklyn's most iconic buildings -- three-to-four story row houses with sandstone facades, typically built between 1850 and 1890. Found throughout Park Slope, Bed-Stuy, Fort Greene, and Cobble Hill.

Roofing characteristics. Most brownstones have pitched or low-slope roofs, often with a rear extension that has a flat or very low-slope section. The original roof was typically slate or tin, though most have been re-roofed with asphalt shingles or modified bitumen.

Common roofing issues. Parapet wall deterioration is the number one problem -- the decorative stone or brick parapets crack and separate from the roof membrane, creating leak paths. The junction between the pitched main roof and flat rear extension is another frequent leak source. Chimney flashing around the original masonry chimney often fails.

Row Houses (Non-Brownstone)

Row houses without brownstone facades are found throughout Brooklyn -- in Bay Ridge, Sunset Park, Bensonhurst, and many other neighborhoods. They share structural similarities with brownstones but often have simpler facades.

Roofing characteristics. Typically pitched roofs with asphalt shingles, though some have flat rear sections. Party walls (shared walls between adjacent buildings) mean that roof problems can affect your neighbor's building too.

Common roofing issues. Party wall parapet leaks, aging shingle systems, and inadequate attic ventilation are common. Many row houses in southern Brooklyn were built with minimal roof ventilation, causing moisture problems in summer.

Walk-Up Apartments (Multi-Family)

Walk-up apartment buildings are Brooklyn's most common multi-family housing -- typically 3-5 stories with flat roofs, found in virtually every neighborhood. These buildings house the majority of Brooklyn's renters.

Roofing characteristics. Almost always flat or very low-slope roofs using EPDM, TPO, modified bitumen, or built-up roofing. Internal roof drains are standard in older buildings, with overflow scuppers as backup.

Common roofing issues. Ponding water from clogged internal drains is the top problem. Membrane deterioration from UV exposure and age. Parapet wall failures. Multiple previous re-roofing layers trapping moisture. Skylight and vent penetration leaks.

Three-Family Homes (Triple Deckers)

Three-family homes -- sometimes called triple deckers -- are common in Flatbush, East Flatbush, and Marine Park. They typically have three separate units stacked vertically with a flat or very low-slope roof.

Roofing characteristics. Usually flat roofs with modified bitumen or EPDM membranes. Some have been converted with rear extensions that create complex drainage scenarios.

Common roofing issues. Similar to walk-up apartments -- drainage, membrane aging, and parapet issues. The challenge is that three separate tenants may report leaks at different times, making it harder to pinpoint the source.

Detached and Semi-Detached Homes

Detached homes are less common in Brooklyn but found in areas like Dyker Heights, Bergen Beach, Mill Basin, and parts of Flatlands. These are typically larger, more suburban-style homes.

Roofing characteristics. Usually pitched roofs with asphalt shingles, sometimes with multiple roof planes, dormers, and valleys. Larger roof surface area means more potential leak points.

Common roofing issues. Valley flashing failures, ice dam formation in winter (especially on north-facing slopes), and multiple roof-plane junctions that require careful flashing detail.
