Which Flat Roof System Is Right for Your Brooklyn Building?
Not all flat roofs are equal. We install three primary membrane systems — each with distinct trade-offs for lifespan, energy efficiency, cost, and suitability for Brooklyn's building stock. We'll recommend the right one for your specific roof.
Best for: New installations, commercial buildings, energy efficiency
- Highly reflective — reduces cooling costs significantly
- Heat-welded seams are the strongest available
- Resistant to UV, punctures, and chemical exposure
- Lightweight — ideal for roofs with load constraints
- White or light grey keeps building cooler in summer
- Roofs that need to be walked frequently (prone to surface scuffs)
- Very old structures with irregular deck surfaces
Best for: Brownstones, townhouses, long-term durability
- One of the longest-lasting flat roof membranes available
- Excellent flexibility — handles Brooklyn's temperature swings well
- Low maintenance once properly installed
- Proven 40+ year track record in NYC
- Cost-effective for mid-size residential roofs
- Buildings prioritizing energy efficiency (black absorbs heat)
- Situations where aesthetics are a primary concern
Best for: Replacements on existing built-up roofs, complex geometries
- Multi-ply system provides excellent redundancy
- Granulated cap sheet adds impact and UV resistance
- Familiar system for older Brooklyn buildings
- Good performance on roofs with many penetrations
- Can be installed over existing built-up roofing in some cases
- Situations requiring maximum energy efficiency
- Very low-slope roofs where drainage is poor
Prices are estimates for typical Brooklyn roofs. Final cost depends on roof size, condition, access, and removal requirements. We provide a firm written quote before any work begins.
Flat Roof Services We Provide in Brooklyn
From emergency repairs to full commercial replacements, we handle every aspect of flat roofing on Brooklyn's residential and commercial buildings.

- Deck inspection & repairs
- New membrane + insulation
- All flashings & drains

Flat Roof Repair
Targeted repairs for leaks, blisters, cracks, seam failures, and flashing problems. We diagnose the source accurately — not just where water appears — and fix it with compatible materials so the repair lasts.
- Leak detection & source finding
- Membrane patch & seam repair
- Flashing replacement
- Drain clearing & reseating

Comprehensive roof assessment for buyers, sellers, property managers, and owners who haven't had an inspection in the last 2 years. Delivered as a written report with photos, condition ratings, and maintenance recommendations.
- Full visual & probe inspection
- Drainage evaluation
- Flashing & penetration check

Drainage & Ponding Solutions
Standing water on a flat roof is a structural and waterproofing liability. We install additional drains, tapered insulation, and scuppers to direct water off the roof properly and prevent the most common cause of membrane failure.
- Drain addition & relocation
- Tapered insulation installation
- Scupper installation
- Internal drain reconstruction
- Flow testing post-installation
Coating & Restoration
For membranes that are aging but not yet failed, a reflective roof coating can extend lifespan 10–15 years and significantly reduce cooling costs. We apply silicone and acrylic coatings to eligible TPO, mod-bit, and built-up roofs.
- Membrane suitability assessment
- Surface cleaning & prep
- Coating application (2 coats)
- Flashing reinforcement
- 5–10 year coating warranty

How a Flat Roof Project Works From Start to Finish
Flat roof projects can feel overwhelming if you've never done one before. We make the process clear and predictable — from the first call to the final warranty document.
No work starts without your written approval.
We never begin installation until you've reviewed and signed the written proposal. No surprises, no scope creep, no upsells on the day of installation.
Free Consultation & Scheduling
Call or submit a request online. We schedule a free on-site estimate within 1–3 business days. No pressure, no commitment — just a straightforward look at your roof.
On-Site Assessment
We inspect the full roof from above — membrane condition, flashing, drains, penetrations, deck integrity, and insulation. We photograph everything and discuss what we find with you directly.
Written Proposal
You receive a written, line-item proposal within 24 hours of the assessment. It includes the recommended system, scope of work, material specifications, timeline, and firm pricing — no vague estimates.
Material Ordering & Scheduling
Once you approve, we order materials from the manufacturer and schedule the installation. Most Brooklyn flat roof projects are scheduled within 2–3 weeks of approval.
Installation
Our crew handles tear-off, deck preparation, insulation, membrane installation, and all flashing details. We keep the site clean, protect the building interior, and complete most residential roofs in 1–3 days.
Final Inspection & Warranty
We conduct a post-installation walkthrough with you, confirm all drains are clear and functional, and provide your written workmanship warranty and manufacturer warranty documentation.

Flat Roof Problems We See Every Week in Brooklyn
Brooklyn's flat roofs face specific challenges: wide temperature swings, heavy summer rain, winter freeze-thaw cycles, and decades of deferred maintenance on older buildings. Here are the problems we diagnose and fix most often.
Visible membrane degradation on a Brooklyn rowhouse
Surface cracking like this typically means replacement within 1–3 years
Standing / Ponding Water
The most common flat roof problem in Brooklyn. Water pooling for more than 48 hours accelerates membrane degradation, adds structural load, and will eventually find any weakness in the system. Caused by inadequate slope, blocked drains, or settled insulation.
Membrane Blistering
Bubbles or blisters in the membrane surface indicate moisture trapped between layers or between the membrane and insulation. Blisters weaken the membrane and will eventually rupture, causing leaks. Common on aging modified bitumen and built-up roofs.
Flashing Failures
The most common cause of leaks on flat roofs that look structurally sound. Flashings at parapets, chimneys, HVAC curbs, skylights, and pipe penetrations degrade faster than the membrane and are the first point of failure on most Brooklyn roofs.
Seam Separation
On EPDM roofs, seams bonded with adhesive can peel over time, especially where the roof flexes due to temperature changes. Separated seams are an open path for water entry and require immediate repair to prevent spreading.
Roof Deck Rot
When leaks go unaddressed, water saturates the insulation and eventually reaches the wood deck beneath. Soft spots when walking the roof, water stains on ceilings, and sagging sections indicate deck damage that must be repaired before re-roofing.
Crack & Split in Membrane
UV exposure and thermal cycling cause flat roof membranes to become brittle over time. Cracking and splitting — especially on mod-bit and older EPDM — indicates end-of-life degradation. Patching extends life temporarily but replacement is typically warranted.
