May and June are the best two months of the year to do a full roof check in Brooklyn. The freeze-thaw damage from winter has already shown itself, hurricane season hasn't started, and rooftop temperatures are still cool enough to walk safely. Here's the 9-point summer maintenance checklist we run on every Brooklyn roof, and what each item actually costs to address.
This is item one for a reason. Most Brooklyn flat roofs have 1-2 interior drains plus side scuppers. Winter winds blow leaves, bagel wrappers, and pigeon nests onto the roof. By May the drain strainers are typically half clogged. Add one summer thunderstorm and water ponds 2-3 inches deep, which:
Clearing drains takes 15 minutes per drain. Wear a mask: there's a lot of bird debris.
Flashing is the metal that wraps the edge of the roof, the chimney base, vent pipes, and skylight curbs. The caulk sealing the flashing edges typically lasts 5-8 years. After that it cracks, water gets behind, and rot starts under the parapet cap. What to look for:
Recaulking with a polyurethane sealant (Sika, BASF MasterSeal, or NP1) is a 1-2 hour job and a typical service call cost of $350-650 for an average Brooklyn roof. It's the highest return preventive maintenance there is.
Surface condition tells you whether the roof has 5+ years of life or is approaching replacement. Look for:
⚠️ Never walk a Brooklyn flat roof in July to August midday. Surface temps on dark asphalt cap sheet hit 160-180°F in direct sun. You leave footprints in the membrane and you risk heat exhaustion. Walk roofs in the morning before 10am or after 5pm in summer.
If your Brooklyn flat roof is asphalt based (modified bitumen, BUR) and is 5+ years old, applying a white elastomeric or aluminum reflective coating in early summer is one of the highest ROI roof investments. It:
Best application window: late May through July, when 5 consecutive dry warm days are most likely.
If your Brooklyn home has any sloped sections (front cornice, rear extension, dormers), check the gutters. Specifically:
Brooklyn has a lot of mature street trees, and a lot of branches overhanging rear roofs from neighbor yards. Branches within 6 feet of the roof cause:
City trees on the sidewalk, only NYC Parks Department can trim. File a service request online. Yard trees on your property, any licensed arborist, typically $400-1,200 per significant tree.
The horizontal masonry surfaces, chimney crowns and parapet wall caps, are the most weather exposed parts of any Brooklyn roof. They crack, leak, and slowly destroy the wall below. Inspect:
Atlantic hurricane season is June 1, November 30. NYC's worst storms historically arrive August to October. Before August, make sure:
The roofs that survive a Brooklyn nor'easter best are the ones where summer maintenance was done. The ones that fail are usually 6-12 months overdue on flashing recaulk and have one clogged drain.
Even with great maintenance, a typical Brooklyn modified bitumen roof has a 15-20 year service life. If yours is 12+ years old, schedule a professional inspection now while contractors have summer availability, not in November when everyone needs roof work and pricing peaks. A pro inspection includes:
Cost: $250-650 depending on size. Money well spent before you put $2,000 into patching a roof that needs replacement.
💡 Insurance tip: Most NY homeowner policies require you to maintain the roof. If you skip annual maintenance and a leak claim arises, the carrier can deny on grounds of "lack of maintenance", even with a recent date of loss. Keep dated photos of every inspection and any work done. It's the cheapest insurance audit defense there is.
You can safely do yourself: clearing drains, removing leaves, photographing surface conditions, cleaning gutters. You should hire a pro for: flashing recaulk, coating application, parapet repairs, anything requiring you to walk near a roof edge without fall protection. Brooklyn flat roofs are unforgiving, and most have parapet walls only 18-24" tall, which is not a guardrail by OSHA standards. The fee for a pro service call is dramatically lower than an ER visit.
