We’ve been repairing roofs in Glendale since the 1980s. We know the 11385 ZIP code well: the attached brick row houses along Cooper Avenue, the semi-detached two-families near Myrtle Avenue, and the tight blocks between Cypress Hills Street and the Cemetery of the Evergreens. These aren’t suburban homes with pitched shingle roofs and wide setbacks. They’re 1920s-1940s masonry construction with flat or very low-slope roofs, parapet walls, and party walls shared with neighbors. That changes everything about how you diagnose a leak, how you price the repair, and what materials you carry on the truck.
Our Roof Repair crews are based in Queens and Brooklyn, which means we’re already nearby when a February freeze-thaw cycle pops a coping stone or pulls counter-flashing away from a party wall. We don’t chase storms from Pennsylvania or Florida. We’re the company that plans to be here in thirty years, because we’ve already been here for over forty-two.

Glendale homeowners call us because we’ve seen their exact roof before. The built-up gravel system from 1978.

When you call (866) 756-1978, a live person answers - nights, weekends, during a nor’easter, doesn’t matter. We don’t do voicemail trees. Our technicians are background-checked, uniformed, and trained to document every inspection with photos from your actual roof, not the driveway. You’ll see what we see. Then we’ll give you upfront pricing: the number on the estimate is the number on the invoice. A square deal, plain and simple.

Our Roof Repair Services in Glendale
Flat Roof Patch
This is the work we do most often in Glendale. Your 1920s-1940s brick row house almost certainly has a flat or low-slope roof finished in built-up roofing, torch-down modified bitumen, or EPDM rubber - not asphalt shingles. When these membrane systems age, they develop splits at seams, punctures from foot traffic or HVAC service, and deterioration where water ponds against parapet walls.
We cut out the failed section, inspect what’s underneath (often two or three previous layers), and install a proper patch using compatible materials. On a recent job on 69th Avenue, we found a 40-year-old built-up system beneath a failing torch-down layer. The coping stone sealant had cracked, and party-wall counter-flashing had pulled away. We stripped the damaged area, re-flashed the parapet with GAF membrane, and replaced the cracked coping stone. Both neighbors stayed dry. A typical flat roof patch in Glendale runs $450-$950.
Flashing Repair
Flashing is where most Glendale roofs actually fail. The counter-flashing where your roof meets a shared party wall. The step flashing around a chimney on a semi-detached home near Forest Park. The coping stone flashing that caps your parapet wall along Cooper Avenue. Queens winters bring freeze-thaw cycling that pries these metal and membrane joints apart, especially when water gets behind coping stones and expands as it freezes.
We don’t just caulk over the crack. We remove the failed flashing, inspect the substrate, install new counter-flashing or membrane-to-metal transitions, and seal with materials rated for the movement these flat roofs experience. Flashing repair in Glendale typically costs $350-$750.
Leak Repair
Leak calls spike every February and March in 11385. That’s freeze-thaw damage working on parapet details through January, then showing up as interior stains when the thaw comes. But not every leak is from the roof surface. We’ve traced leaks to failed vent boots, separated valley membranes on low-slope additions, and - very commonly in Glendale - gaps in party-wall counter-flashing that channel water from one attached unit into the next.
Our leak repair starts with a systematic inspection, not guesswork. We document with photos, identify the true source, and fix it. Most Glendale leak repairs run $400-$1,100, with emergency same-day service available when water is actively entering your home.
Shingle Replacement
Shingle work is less common in Glendale’s core row-house blocks, but we do see it on semi-detached homes near the Cemetery of the Evergreens and on additions or dormers where a previous owner installed pitched roofs. When shingles blow off in a Queens windstorm or curl from age, we match what exists or recommend an upgrade to Atlas or Tamko architectural shingles if the roof is near end of life. Spot shingle replacement in Glendale typically costs $300-$650; partial re-shingling runs $800-$1,800.

Trusted Brands We Service in Glendale
We carry membrane, flashing, and repair materials from IKO, Atlas, and Tamko on every Glendale service call, plus GAF, CertainTeed, Owens Corning, and Boral for larger repairs or full recoveries. Because we’re an authorized installer for all seven manufacturers, we don’t substitute generic materials when your warranty or building code calls for a specific product. For Glendale’s flat-roof housing stock, that means proper modified bitumen, EPDM, and built-up system components - not whatever was cheapest at the supply house last week. We stock for same-day completion because we know you don’t want a tarp on your roof any longer than necessary.
Common Roof Repair Problems We See in Glendale Homes
- Failed counter-flashing at shared party walls. Queens freeze-thaw cycling pulls metal flashing away from brick party walls, and because Glendale’s row houses share continuous walls, a gap on one side routinely channels water into a neighboring unit’s ceiling. We diagnose the full path and quote repairs that protect both properties.
- Ponding on low-slope roofs from deteriorated built-up or torch-down layers. Decades of Glendale’s 1920s-1940s construction have left stacked layers of aging material that no longer sheds water. We cut out failed sections and install proper tapered insulation or crickets where ponding has become chronic.
- Cracked coping stones on parapet walls trapping freeze-thaw water. Water gets behind coping stones, freezes, and pries apart mortar and flashing. Every February and March, we see the predictable surge of interior leak calls from this exact failure mode across 11385.
- Deteriorated vent boots and pipe flashing on aging flat roofs. Rubber boots around plumbing vents harden and crack after years of UV exposure on Glendale’s flat roofs, creating small but persistent leaks that show up as ceiling stains below bathrooms.

FAQs - Roof Repair in Glendale
Because your attached brick rowhouse shares continuous party walls with neighboring units, a gap in counter-flashing or a cracked coping stone on your roof can channel water horizontally into the adjacent property’s top-floor ceiling before it ever shows in yours. We frequently diagnose leaks that span two separately-owned properties and quote repairs that protect both sides. Call (866) 756-1978 - we’ll trace the full water path and give both owners a clear, upfront price.
Almost certainly a flat or very low-slope roof finished in built-up roofing, torch-down modified bitumen, or EPDM membrane - not asphalt shingles. The 1920s-1940s brick housing stock in 11385 was built with masonry parapet walls and roof decks designed for these systems. If you’re unsure what’s up there, our inspection includes photos from your actual roof surface. Call for a free look.
Water that gets behind coping stones or into flashing gaps freezes overnight, expands, and pries apart mortar and metal joints - then thaws the next day and leaks inward. This cycle repeats dozens of times each Queens winter, which is why parapet and flashing failures surge predictably every February and March in Glendale. Preventive inspection in fall can catch cracked coping stones before the cold sets in.
Many Glendale built-up roofs can be sectionally patched if the underlying substrate is sound and the damage is localized to one area or seam. We cut out the failed section, inspect what’s beneath, and tie the new membrane into existing material with proper overlap and seal. Full replacement becomes necessary when multiple layers are saturated, the deck is compromised, or patching would create more seams than a new membrane. We’ll show you photos and give you both options with honest pricing.
Yes - the NYC Department of Buildings requires a permit for most roof work, and shared party-wall repairs on attached row houses often need additional coordination since the roofline is physically continuous across separately-owned properties. We handle the DOB filing as part of our service. You won’t need to navigate the permit office yourself. Call (866) 756-1978 and we’ll explain what’s required for your specific repair.
