The best roofers in Park Slope, by what you need
A leak rarely announces itself politely. It shows up as a brown ring on a top-floor ceiling, usually after the first hard rain of the season, and on a Park Slope brownstone the culprit is almost always the flat roof or the masonry parapet that frames it. Roofing here is also one of the higher-ticket hires you'll make, with a full flat-roof replacement commonly landing between $8,000 and $25,000.
Three picks, by what you actually need. Each one is a flat-roof specialist holding a currently-active NYC Home Improvement Contractor (HIC) license, the consumer-protection license the city requires for residential roofing over $200. There is no separate roofing license in New York, so the HIC is the one to verify.
Best for flat-roof repair, re-coating, and the most-recommended option
Roofmaster
$$$ · flat-roof repair · re-coating & leak fixes
The single most-recommended roofer in our pool, and the pick when the job is a brownstone flat-roof leak or a worn membrane you'd rather re-coat than tear off. Neighbors on both Park Slope Parents and the Brownstoner forum keep coming back to Mike at Roofmaster: 'straightforward, awesome guy, great problem solver, fixed two of our roofs.' Quotes run pricier than some, but the work is the part people praise. The South Slope base on 19th Street keeps it genuinely local.

Best established family firm for responsiveness and full replacements
Premier Roofing Co., Inc.
$$$ · flat-roof replacement · skylights & waterproofing
The pick when you want a long-running family firm that picks up the phone and does the bigger jobs: full flat-roof replacement, leak detection, skylights, roof hatches, and waterproofing. Nine Park Slope Parents reviews back Premier, with the owner Anthony called 'a great guy and total straight shooter' and the firm 'very responsive and professional.' Based at 905 Atlantic Avenue in Clinton Hill, a short hop from the Slope. Its registry record matched cleanly on name, address, and phone, so there's no doubt who you're hiring.

Best for flat-roof maintenance and stubborn leaks others couldn't solve
Kamco Roofing
$$$ · flat-roof maintenance · tough leak repair
The pick for the leak nobody else could trace, and for keeping a flat roof in shape over time. A Park Slope Parents reviewer hired Kamco for flat-roof maintenance done to an inspector's spec and said they 'solved a problem no one else could fix.' Family-owned with a stated 70-plus years of combined experience, they also handle gutters. If you've already had one roofer out and the ceiling's still staining, this is the second opinion.

In short: Roofmaster for flat-roof repair and re-coating (and the most-recommended option), Premier for an established family firm and full replacements, Kamco for maintenance and the stubborn leak nobody else could trace.
What does a roof repair or replacement cost in Park Slope?
Roofing budgets here are driven by one thing first: repair versus replace. A small-to-medium flat-roof leak patch in Brooklyn runs roughly $400-$1,500, per NY Roofing Hub, while a full flat-roof replacement on a typical townhouse lands around $8,000-$25,000, per NY Roofing. The current Brooklyn ranges:
| Scope | Typical Brooklyn range |
|---|---|
| Minor flat-roof leak patch | ~$400-$1,500 |
| Larger leak / multi-spot repair | ~$1,000-$2,500 |
| Flat-roof replacement (per sq ft, installed) | ~$8-$18 |
| EPDM / TPO membrane (per sq ft) | ~$8-$14 |
| Full flat-roof replacement (typical townhouse) | ~$8,000-$25,000 |
Two Park Slope realities push these numbers up. First, NYC roof work runs roughly 20-35% above national averages because of licensing, permitting, and the logistics of getting crews and materials onto a narrow brownstone block, per AlterPhase Roofing. Second, the parapet walls that ring a brownstone roof can hide masonry and flashing problems that aren't visible until the roof is opened up. EPDM rubber membrane is the popular flat-roof choice here, durable enough to last decades with maintenance, per NY Roofing. Treat any number quoted before a site visit as a placeholder. The real figure comes from a line-item scope.
Frequently asked questions
- How much does a flat roof cost to repair or replace in Brooklyn?
- A small-to-medium flat-roof leak repair in Brooklyn typically runs about $400-$1,500, with more involved repairs commonly $1,000-$2,500 depending on access and severity, per NY Roofing Hub and AlterPhase Roofing. A full flat-roof replacement on a typical Brooklyn townhouse runs roughly $8,000-$25,000, about $8-$18 per square foot installed, per NY Roofing. NYC work tends to run 20-35% above national averages because of permitting, licensing, and building-access logistics. Get a written, line-item scope before you commit.
- Does a roofer in NYC need a special roofing license?
- No. New York has no separate residential roofing license. For roofing work on a 1-4 family home, the credential to verify is the NYC DCWP Home Improvement Contractor (HIC) license, the same consumer-protection license general contractors carry. Any home-improvement work over $200 on a small home requires it. The HIC is tied to a public complaint and disciplinary record and governs your contract, so hiring without it can void that protection. Every roofer on this list holds a currently-active HIC.
- How do I verify a roofer's HIC license?
- Look the business up in NYC's public license records. The DCWP license search, and the NYC Open Data 'Issued Licenses' dataset behind it, lists every Home Improvement Contractor by name and number, with current status and expiration. Confirm the license reads 'Active' with a future expiration, and that the name matches the exact company you're hiring, not a similar one. Every roofer here was checked this way, and each card's address comes from that same license record.
- What are the red flags when hiring a roofer?
- Watch for no verifiable HIC license, a demand for a large cash deposit up front, door-knocking storm-chasers, pressure to sign same-day, and refusal to put a line-item scope in writing. A vague 'we'll see when we open it up' with no contingency, or a price far below every other quote, are also warning signs. A legitimate roofer carries an active HIC plus liability and workers' comp insurance, and is happy to give references.
- Do I need permits to replace a Park Slope brownstone roof?
- Often, yes. A like-for-like flat-roof repair usually doesn't need a permit, but a full replacement, new roof structure, or work that changes the roofline typically requires a NYC Department of Buildings permit pulled by a licensed pro. Much of Park Slope sits in a landmarked historic district, so anything visible from the street, a roofline change, a deck, or a bulkhead, can need Landmarks Preservation Commission approval too. Ask your roofer who pulls the permits before work starts.
- What's the best flat-roof material for a Park Slope brownstone?
- EPDM rubber membrane is the popular choice on Brooklyn brownstones: durable, weather-resistant, and able to last decades with maintenance, per NY Roofing. TPO is another common single-ply membrane. Both run roughly $8-$14 per square foot installed in Brooklyn. The right pick depends on your roof's slope, drainage, and how it ties into the parapet walls, which is exactly the kind of call a flat-roof specialist should walk you through on a site visit before quoting.
How do you verify a roofer's HIC license?
Here's the part that protects your money, and it's simpler than for a full gut. There is no separate roofing license in New York. For roofing work on a 1-4 family home, the credential to check is the DCWP Home Improvement Contractor (HIC) license, the same consumer-protection license a general contractor carries. Any home-improvement work over $200 requires it, roofing included. The HIC governs your contract and ties the business to a public complaint and disciplinary record, so it's your recourse if a job goes wrong.
To check it: search the DCWP license lookup, or the NYC Open Data "Issued Licenses" dataset behind it, by business name or license number. Confirm the license reads Active with a future expiration, and that the name matches the exact company you're hiring.
That last part matters more than it sounds. Roofing has a lot of similarly-named firms and marketing umbrellas, and a license registered to a different company doesn't protect you. We confirmed all three picks against an active HIC in the city's public license records, each expiring February 2027, and we took each card's address from that same authoritative record. Where a marketed phone number differed from the registry's filing number, we flagged it and used the local business line rather than guessing.
What should you ask before hiring a roofer?
Five questions separate a real roofer from a storm-chaser:
- Do you hold a current NYC HIC license, and what's the number?
- Do you carry general liability and workers' comp insurance?
- Is this a repair or a replacement, and why? (A patch shouldn't be sold as a tear-off, or vice versa.)
- Will you check the parapet walls and flashing, not just the membrane?
- Can I see a line-item scope and a recent local reference?
Then put it in writing: a defined scope and a payment schedule tied to milestones, never a large cash deposit up front. Door-knocking after a storm, same-day pressure, and a price far below every other quote are the classic red flags.
How did we vet these roofers?
Two filters. Community signal: every roofer here turns up where Park Slope neighbors actually trade names for a leaking roof. That means Park Slope Parents reviews and the Brownstoner forum, where the same names recur with specifics rather than star ratings. The license: we matched every name, by exact business name, to a NYC DCWP Home Improvement Contractor (HIC) license reading currently active in the city's public license records, each expiring February 2027. Each card's address comes from that same record.
A note on what's not here. The three picks are all flat-roof specialists, which is the dominant roof type on a Park Slope brownstone, so the guide is coherent as a flat-roof guide. But it doesn't yet cover slate or pitched roofs, or a dedicated masonry-and-waterproofing combo. Several names neighbors mention were held back rather than listed on reputation alone: one had a lapsed HIC, and a few had no verifiable HIC under the brand they advertise with. We'd rather leave a slot empty than recommend a roofer we couldn't confirm.
