East New York’s Reliable Roof Repair Company

Most of my roof leak repair calls in East New York start the same way: someone calls Dennis Roofing after water’s already dripping through a bedroom ceiling or flooding into a storefront, panicking about what it’ll cost. When I climb onto the roof, I’ll find the problem-usually a small crack in the parapet flashing, a tiny puncture in the EPDM membrane, or a couple of missing shingles-that’s been there for months. The actual leak? Maybe $300-$800 to fix. The damage inside from waiting? Easily $2,000-$5,000 in drywall, mold remediation, and ruined belongings. A simple roof inspection twice a year-something we do for $150-$225 depending on building size-catches these problems when they’re still cheap and easy.

I’m Renee, and I’ve been doing roof repair and replacement in East New York for 14 years now. Started as a super on a six-unit walk-up off New Lots Avenue, spent half my time chasing leaks with buckets and caulk tubes, and finally got tired of watching the same contractors come back every spring with temporary fixes. Joined a professional crew, learned flat roofing systems the right way, and came to Dennis Roofing to bring honest, no-surprises service to the neighborhood I grew up in. What I do now is pretty straightforward: I show up, take photos of your roof, explain what’s wrong in plain language, and give you real options-repair vs. replacement, how long each will last, and what it’ll actually cost.

When You Need Roof Repair vs. Full Replacement

The biggest question property owners ask me: can this roof be repaired, or do I need to replace the whole thing? Here’s how I walk through it on every job.

For flat roofs-which cover most of the brick walk-ups along Pitkin, Pennsylvania Avenue, and Sutter-I’m looking at the membrane condition and how many layers are already up there. An EPDM rubber roof that’s 12-15 years old with one or two small punctures or seam failures? That’s a repair, usually $400-$950 depending on access and materials. I clean the area, patch or re-seam it properly, and you’re good for another 3-5 years. Same roof but with widespread cracking, multiple ponding areas that stay wet for days, or three old layers underneath? That’s replacement territory-$6,800-$12,500 for a typical 20×40-foot flat roof on a two- or three-story building, fully stripped and done right with new EPDM, TPO, or modified bitumen.

On a three-story over on Pitkin last year, the owner had patched the same corner four times in two years. When I pulled back the rubber, I found the insulation underneath was soaked through and the deck had soft spots. No amount of patching was going to fix that-the moisture had compromised the structure. We did a full tear-off, replaced damaged decking, added proper tapered insulation for drainage, and installed a new 60-mil EPDM system with a 15-year warranty. Cost was $9,200, but that roof won’t leak again, and his heating bills dropped because the insulation actually works now.

Shingle roofs on East New York’s single- and two-family homes are easier to evaluate. If you’ve lost a few shingles after a storm or have localized damage around a chimney or valley, that’s a $350-$750 repair-we replace the damaged section, match the shingles as close as possible, and seal it up. But if your asphalt shingles are 20+ years old, curling across the whole roof, or you’re seeing granules washing into the gutters, it’s time for a new roof. A full shingle replacement on a typical 1,200-square-foot home runs $7,500-$11,000 including tear-off, new underlayment, architectural shingles, and updated flashing. That gives you another 25-30 years with minimal maintenance.

What a Real Roof Inspection Should Include

Too many “inspections” in East New York are a guy spending five minutes on the roof, snapping a couple phone photos, and telling you it’s fine or needs total replacement-nothing in between. When I do a roof inspection, here’s what you’re paying for:

• Membrane or shingle condition: I’m checking for cracks, blisters, punctures, missing or damaged shingles, and how much life is left in the material itself.
• Flashing and penetrations: Chimneys, vents, skylights, and parapet walls-these are where 80% of leaks start. I check every seal, every piece of metal flashing, and every roof-to-wall transition.
• Drainage: On flat roofs, I’m looking for ponding water (anything that sits more than 48 hours after rain), clogged drains, and whether the roof slopes properly to the drain points. On pitched roofs, I check gutters and downspouts.
• Interior signs: If I can access the top floor or attic, I look for water stains, mold, daylight coming through, and insulation damage-these tell me where water’s been getting in even if the roof looks okay from above.
• Structure: Soft spots, sagging areas, or visible deck damage that needs immediate attention.

After the inspection, you get a detailed report with photos, a condition rating (good / fair / poor / failing), and specific recommendations: do nothing, repair these three areas, plan for replacement in 2-3 years, or replace now. No pressure, just information so you can budget and plan.

Common Roof Repairs We Handle in East New York

Most of my work involves fixing problems before they become emergencies. Here’s what that looks like day-to-day:

Roof leak repair starts with roof leak detection-finding where water’s actually getting in, which isn’t always directly above the interior stain. Water travels along beams, pipes, and between layers before it drips through your ceiling. I use a combination of visual inspection, water testing, and sometimes infrared scanning on larger commercial buildings to pinpoint the entry point. Once I find it, the repair depends on the roof type: patching and sealing EPDM or TPO membranes, replacing damaged shingles and underlayment, or rebuilding failed flashing. Cost: $300-$1,200 for most leak repairs, completed same-day or next-day in non-emergency situations.

Chimney flashing repair is huge in East New York’s older housing stock. Those brick chimneys on two-family homes and small apartment buildings develop gaps between the masonry and the metal flashing, especially after years of freeze-thaw cycles. Water gets in, runs down inside the walls, and shows up as stains on the top floor or even the floor below. We remove the old flashing, re-point any damaged brick, install new step flashing and counter-flashing properly embedded in the mortar joints, and seal everything with high-grade roof sealant. Typical cost: $650-$1,400 depending on chimney size and accessibility.

On a corner store with apartments above near Pennsylvania Avenue, the owner kept repairing interior water damage every winter. Turned out the chimney flashing had failed five years earlier, and water was running down inside the brick, soaking the framing and insulation. We rebuilt the flashing correctly, treated the mold inside, and installed a new chimney cap. No leaks in three years since. One proper repair instead of five bad patches.

Flat Roofing Systems: What Works in East New York

Let’s talk about the roofs on most of our multifamily and commercial buildings. East New York has thousands of flat roofs-or more accurately, low-slope roofs-on brick walk-ups, row houses, small stores, and light industrial buildings. The right system depends on your building, your budget, and how long you plan to own the property.

EPDM roofing (rubber roof) is what I install most often on residential buildings. It’s durable, relatively affordable, and handles our weather well-winter cold, summer heat, and the ponding water that’s inevitable on older buildings without perfect drainage. A fully-adhered or mechanically-attached EPDM system costs $6.50-$9.50 per square foot installed, lasts 20-25 years with minimal maintenance, and repairs are straightforward when needed. The seams are the weak point-they need proper prep and sealing-but done right, EPDM is bulletproof.

TPO roofing has become popular on commercial buildings and newer construction because the seams are heat-welded instead of glued, making them stronger and more reliable long-term. TPO is also highly reflective (bright white), which reduces cooling costs in summer-a real benefit on a building with tenants running AC units all season. Cost is similar to EPDM, $7-$10 per square foot, with a 20-25 year lifespan. If you’re doing a full flat roof installation on a commercial building or larger apartment building, TPO is worth considering.

Modified bitumen roofing is the modern version of old tar and gravel roofs-a rubberized asphalt membrane applied in layers, usually with a torch or hot mop. It’s tough, handles foot traffic well, and is less likely to puncture than single-ply membranes. I see it most often on buildings with roof equipment (HVAC units, water tanks) or regular rooftop access. Cost: $7-$11 per square foot. Lifespan: 15-20 years. The seams are strong because they’re melted together, but installation requires more skill and care than peel-and-stick systems.

Tar and gravel roofs (built-up roofing) are the old-school system on buildings from the 1950s-1980s-layers of tar paper and hot asphalt topped with gravel. They work, but they’re heavy, messy to install, and when they fail, they often fail catastrophically because you can’t see problems developing under the gravel. If you have one that’s nearing the end of its life (20-25 years), I usually recommend switching to EPDM or modified bitumen on the replacement. If it’s still in decent shape, we can extend its life with a roof coating-more on that below.

Shingle, Metal, and Other Roof Types

While flat roofs dominate the apartment buildings and commercial strips, East New York’s residential blocks near Linden Boulevard and along the numbered streets have plenty of pitched roofs on single-family homes, two-families, and smaller row houses.

Asphalt shingle roofing is the most common and cost-effective option for these homes. Standard three-tab shingles are inexpensive but only last 15-18 years in our climate. I steer clients toward architectural (dimensional) shingles-they cost about 20% more upfront but last 25-30 years, look better, and handle wind better. A complete shingle roof replacement on a typical 1,200-1,500 square foot home costs $7,500-$11,000 including tear-off, disposal, new underlayment (we use synthetic underlayment now, not the old felt paper), ice-and-water shield on eaves and valleys, and proper ridge venting. Color choice matters more than people think-lighter colors reflect heat and can drop your cooling costs; darker colors absorb heat, which helps melt snow in winter but makes your top floor hotter in summer.

Metal roofing has gained popularity because it lasts 40-50 years, sheds snow and rain quickly, and is virtually maintenance-free once installed. Standing-seam metal roofs look clean and modern; they’re popular on contemporary renovations and new construction. Corrugated metal panels are more industrial but work well on garages, sheds, and mixed-use buildings. Cost: $11-$16 per square foot installed, so a 1,200-square-foot metal roof runs $13,000-$19,000. That’s roughly double the cost of architectural shingles, but you’ll never replace it again, and insurance companies sometimes offer discounts because metal roofs are fire-resistant and wind-resistant up to 120+ mph.

Emergency Roof Repair and Storm Damage

East New York gets hit hard by nor’easters, summer thunderstorms with straight-line winds, and occasional remnants of hurricanes pushing up the coast. When a storm tears shingles off, collapses a section of flat roof, or drives rain through a compromised area, you need emergency roof repair fast-not next week when the contractor has an opening.

Dennis Roofing offers 24/7 emergency response for active leaks and storm damage. When you call, here’s what happens: I assess the situation over the phone (where’s the leak, how bad, is water actively coming in), give you a realistic ETA (usually 2-4 hours for true emergencies), and explain what we’ll do. Emergency work focuses on stopping the water and securing the building-tarping damaged areas, sealing active leaks, removing standing water from flat roofs, and making temporary but effective repairs to get you through until permanent work can be scheduled. Cost: $450-$1,200 for most emergency calls depending on time of day, severity, and materials needed.

After the storm passes, we come back to assess the full damage, document everything with photos for your insurance claim roofing process, and provide a detailed written estimate for permanent repairs. I’ve worked with dozens of homeowners and building owners through insurance claims-I know what adjusters need to see, how to document wind damage and storm damage properly, and what repairs are likely to be covered vs. what you’ll pay out of pocket. We can bill your insurance company directly in many cases, or work with you on payment plans if you have a large deductible.

Gutters, Skylights, and Roof Accessories

Your roof doesn’t work in isolation. Gutters, downspouts, skylights, and other components all affect how well your roof protects the building.

Gutter installation and gutter repair are critical on both flat and pitched roofs. Clogged or damaged gutters cause water to back up under shingles, overflow onto walls and foundations, and contribute to basement flooding. On flat roofs, internal drains and scuppers do the same job-they have to stay clear or water ponds on the roof, accelerating membrane deterioration. We install seamless aluminum gutters ($8-$12 per linear foot installed), repair sagging or separated sections, and clear blockages. For buildings with chronic clogging problems-especially those with lots of trees nearby-I recommend gutter guards or more frequent cleaning service (we offer seasonal maintenance contracts).

Skylight installation can transform a dark top-floor apartment or attic space, but only if it’s done right. Cheap skylights or improper flashing are leak factories. We use quality skylights from Velux or similar manufacturers, install them with proper curb mounting and multi-layer flashing, and integrate them seamlessly with your roof system. Cost: $1,200-$2,400 per skylight installed including materials, flashing, and interior finishing trim. Skylight repair-replacing cracked glass, rebuilding failed flashing, or fixing condensation issues-runs $350-$800 depending on the problem.

Extending Your Roof’s Life: Maintenance, Coating, and Waterproofing

Not every roof problem requires replacement or even major repair. Sometimes the smartest move-especially if your roof is halfway through its expected lifespan-is preventive maintenance and protective treatments.

Roof maintenance should happen twice a year: spring and fall. For flat roofs, that means clearing drains and gutters, checking seams and flashing, removing debris, and addressing small issues before they become leaks. For shingle roofs, it means checking for damaged or missing shingles, clearing moss and algae, inspecting flashing, and ensuring proper attic ventilation. We offer maintenance contracts-$400-$650 per year for residential buildings, $800-$1,500 for larger commercial properties-that include two inspections, minor repairs up to a set limit, and priority emergency service.

Roof coating is one of the best-value services we provide. A high-quality elastomeric or silicone roof coating adds 5-10 years of life to an aging flat roof for a fraction of the cost of replacement. We clean the roof thoroughly, make necessary repairs to seams and punctures, then apply the coating-it seals the entire surface, reflects UV rays, and provides a new waterproof layer. Cost: $2.50-$4.50 per square foot, so a 1,000-square-foot flat roof gets coated for $2,500-$4,500. It’s not magic-if your roof is structurally failing or has widespread damage, coating won’t save it-but for a roof that’s 12-15 years old with surface wear but solid underlying structure, it’s a game-changer.

Roof waterproofing goes beyond basic coatings to address persistent moisture issues. On buildings with parapet walls, we apply waterproof membranes to the wall caps and transitions. On buildings with chronic leaks around penetrations, we rebuild those areas with modern waterproofing details-layered flashing, sealants, and membranes that work together. On buildings with interior moisture problems, we improve ventilation and insulation to prevent condensation from forming on the underside of the roof deck.

Commercial Roofing in East New York

East New York’s commercial corridors-Atlantic Avenue, Pennsylvania, Pitkin, and New Lots-have everything from small retail storefronts to auto repair shops, warehouses, light manufacturing, and mixed-use buildings with businesses on the ground floor and apartments above. Commercial roofing requirements are different from residential: more foot traffic, rooftop equipment (HVAC, exhaust fans), higher wind and code requirements, and often the need to maintain business operations during roof work.

For commercial roof repair, speed and minimal disruption are key. We schedule work during off-hours when possible, section off work areas to keep parts of the roof accessible, and complete projects in phases if needed. Common commercial repairs include resealing around rooftop units, rebuilding membrane sections damaged by foot traffic or equipment installation, upgrading inadequate drainage systems, and addressing leaks that affect inventory, equipment, or tenant spaces.

For roof replacement on commercial buildings, TPO and modified bitumen are the most popular choices. Both handle the demands of commercial use, meet code requirements, and offer good warranties. We work with building owners to minimize downtime-often we can complete a 3,000-5,000 square foot commercial roof replacement in 3-5 days depending on weather and complexity. Cost: $18,000-$40,000+ depending on size, system chosen, and existing conditions.

Working With Dennis Roofing

When you call us, here’s how the process works. You describe what’s going on-leak, visible damage, old roof, whatever-and we schedule an inspection at a time that works for you, usually within 24-48 hours (same-day for emergencies). I come out, spend 30-45 minutes evaluating your roof inside and out, take photos, and sit down with you to explain what I found. You get a written estimate that breaks down the work, materials, timeline, and cost. No pressure, no rush. If you want to think about it, talk to your family, or get other quotes, that’s fine-I’ll email you everything so you have it in writing.

If you decide to move forward, we schedule the work based on your timeline and our availability, usually 1-3 weeks out for non-emergency jobs. We pull necessary permits, order materials, and confirm everything a few days before we start. On job day, we show up on time, protect your property, complete the work efficiently, clean up thoroughly, and do a final walkthrough with you to make sure you’re satisfied. You get warranty information, maintenance recommendations, and our contact info for any questions down the road.

I’ve been doing this in East New York long enough to know what works and what doesn’t, what’s a fair price and what’s a rip-off, and which shortcuts come back to bite you in three years. My goal is simple: fix your roof right the first time, give you realistic expectations on how long it’ll last, and be here when you need maintenance or repairs down the road. East New York’s buildings-the walk-ups my grandmother lived in, the corner stores my neighbors run, the homes families have owned for generations-they deserve roofs that work, contractors who show up, and repairs that last. That’s what we do at Dennis Roofing.
