About Us

Why Park Slope Homeowners Call Us First

Hiring a roofer in Park Slope, Brooklyn isn’t like hiring someone to mow a lawn. You want a crew that won’t cut corners on a building that’s survived a century of NYC winters — and that starts with proper licensing, insurance, and pricing you can actually see in writing before work begins.

That’s the bar we’ve held ourselves to in Brooklyn since 1998. Every roofing estimate is itemized. Every job is covered. And every crew member understands that a brownstone roof isn’t something you experiment on.

Built for Brownstones, Not Just Any Roof

A lot of companies treat every job the same. Park Slope doesn’t allow for that. Between landmarked facades, flat rear additions, and rooflines that were never meant to be standardized, this neighborhood demands a roofing company near Park Slope that actually understands pre-war construction, not one applying a generic playbook to a building it wasn’t designed for.

We work on:

Flat roof extensions and rear additions common on brownstones
Pitched and mansard roofs on historic homes
Flat commercial roofs on retail and mixed-use buildings along the avenues
Roof decks and outdoor living spaces built into older structures
Parapet walls, chimneys, and other rooftop masonry that flat and pitched roofs both tie into

We see the same rear-extension, parapet, and flashing issues on brownstones across Clinton Hill and Brooklyn Heights; pre-war construction doesn’t change much block to block.

For pitched and shingle roofs, we’re a certified installer of GAF roofing systems, one of the most trusted names in the industry for durability.

Brownstone Roof Restoration Done Right

A brownstone roof isn’t just a membrane, it’s parapet walls, cornices, chimneys, and drainage that all have to work together, often on a structure that’s 100+ years old. It’s the same story we deal with on roof restoration jobs in Prospect Heights, Our brownstone roof restoration work covers the whole system, not just the visible layer:

Parapet wall repair — repointing, flashing, and cap repair where water most often finds its way in on Brooklyn brownstones
Roof deck and drainage correction on rear extensions
Chimney and vent flashing tie-ins
Cornice and roofline assessment before any membrane work begins

When Something's Actually Wrong With Your Roof

Most calls we get aren’t proactive — they’re “there’s a stain on my ceiling” or “water’s coming in somewhere near the chimney.” Here’s what that usually turns out to be:

Flashing that’s pulled away from a chimney or vent
Water pooling on a flat roof extension after heavy rain
A membrane that’s cracked, punctured, or separated at the seams
Storm damage nobody noticed until the next rainfall
Shingles that are missing or cracked after a windy week
Gutters pulling away, overflowing, or backing up onto the roofline

If any of that sounds familiar, it starts with a proper roof inspection in Brooklyn, NY — not a guess from the sidewalk.

We can usually get someone out within a day or two of your call, and if it’s an active leak, we treat it like the emergency it is — not something that gets scheduled for “sometime next week.”

Gutter Repair in Park Slope

Gutters don’t get much attention until they fail — and on brownstones, a clogged or pulled gutter sends water straight down a facade that’s already dealing with a century of wear. Our gutter repair work covers reattachment, resealing seams, correcting pitch so water actually drains, and replacing sections that have rusted or rotted through. We’ll usually flag gutter issues during any roof inspection or repair call, since the two are almost always connected.

Full Roof Replacements, Done Right

Sometimes a repair isn’t enough — the roof’s past its useful life, or the damage is too extensive to patch piecemeal. When that’s the case, we walk you through a straightforward roof replacement in Park Slope, Brooklyn:

Flat Roofing Park in Park Slope Needs Different Expertise

If your roof is flat whether it’s a brownstone extension or a commercial building on 5th Avenue you’re dealing with a different set of problems than a sloped roof. Ponding water, failed seams, and worn membranes are common roofing problems that can quickly worsen when left unaddressed.

For flat roof repair in Park Slope, we work with several roofing systems and recommend the right solution based on your building’s structure, existing roof condition, drainage, and long-term performance needs.

TPO Roofing — A durable, energy-efficient membrane with a reflective surface that can help reduce heat absorption and is well suited for many residential and commercial flat roofs.
EPDM Roofing — A flexible rubber roofing membrane known for its durability and resistance to changing temperatures, making it a practical option for Brooklyn’s seasonal weather.
Modified Bitumen Roofing — A multi-layer roofing system that provides reliable waterproofing and is commonly used on older buildings, extensions, and properties with more traditional roof structures.
Roof Coatings — When a flat roof is still structurally sound but showing signs of wear, a protective roof coating can help extend its service life, improve water resistance, and protect the existing membrane from weather exposure.

We install the same flat roofing systems on commercial and mixed-use buildings in Williamsburg, where flat roofs are just as common as they are along Park Slope’s avenues.

All three systems can perform well through NYC’s humid summers and harsh winters, which is why we don’t recommend a one-size-fits-all roofing material. Instead, we select the system based on your roof’s condition, structure, drainage, and specific performance needs. A leak doesn’t check the clock before it starts. If you’ve got active water coming in, storm damage, or a ceiling that’s starting to sag, call us and we’ll prioritize getting someone out fast — whether that means a temporary tarp to stop the bleeding or a same-day repair, followed by a permanent fix once conditions cooperate.

Frequently Asked Questions

How much does a roof replacement cost in Park Slope, Brooklyn?

Cost depends on roof size, material choice (shingle, TPO, EPDM, modified bitumen), and the condition of the decking and flashing underneath. We provide a written, itemized estimate after an on-site inspection — never a phone quote.

Do you carry the licensing and insurance to work on older homes?

Yes — we’re fully licensed and insured for residential and commercial roofing work throughout Park Slope and the rest of Brooklyn.

How often should a brownstone roof be inspected?

We recommend it at least once a year, plus after any major storm. Flat roof extensions common on Park Slope brownstones are especially prone to slow leaks that don’t show up until there’s already interior damage.

What's the difference between EPDM,TPO and modified bitumen for flat roofs?

TPO, EPDM, and modified bitumen are all commonly used flat-roof systems, but they differ in their materials, installation methods, and performance characteristics. TPO is a reflective, energy-efficient membrane; EPDM is a flexible rubber membrane known for durability and weather resistance; and modified bitumen is a multi-layer system often used on older buildings and traditional roof structures.

The right option depends on factors such as your building’s structure, roof condition, drainage, usage, and long-term roofing needs

Have you worked on landmarked or older brownstones before?

Regularly. We understand the material and structural considerations that come with pre-war buildings, and we work within whatever landmark or building requirements apply to your property.
