Call (866) 756-1978

Astoria’s housing stock is unlike anywhere else in the five boroughs. The dense blocks of attached and semi-detached brick buildings - most thrown up between 1910 and 1955 - were built with flat roof decks and brick parapet walls, not pitched shingles. That means the roofer you want is a membrane and flashing specialist, not a shingle crew that happens to work in Queens. Our Specialty Roofing team trains specifically on modified bitumen, built-up roofing, TPO, and the parapet masonry work that goes with them.

Our technicians are background-checked, uniformed, and trained to document every inspection with photos from your actual roof, not the driveway. We hire local crews and train apprentices into journeymen. We’ll be in town in thirty years. That’s the difference between a contractor who lives here and one who chases hailstorms.

A live person answers every call, 24/7. Nights, weekends, the middle of a February storm when your coping cap has cracked and water’s coming through the plaster. No voicemail trees. No callback windows. Call (866) 756-1978 and someone picks up.

We know the local logistics that out-of-area contractors underestimate. Party walls between attached buildings. Coordinating access with neighbors. NYC DOB permit requirements for two-family homes. The specific mortar mixes that hold up in Astoria’s salt-laden coastal air. This is not generic roofing knowledge. It’s Astoria roofing knowledge.

Our Specialty Roofing Services in Astoria

Modified Bitumen Roofing

Modified bitumen is the workhorse of Astoria’s flat roofs, and for good reason. The torch-applied or self-adhering membranes stand up to foot traffic, resist the punctures from HVAC maintenance crews, and flex with the building movement that comes with age. On a typical 20-by-30-foot rowhouse roof in the 11103 ZIP, a two-ply modified bitumen system runs $4,500-$7,200 including tear-off, parapet flashing, and new counter flashing. We install modified bitumen from CertainTeed and IKO, both rated for the temperature swings and UV exposure that Queens flat roofs endure.

We recently repaired a parapet on a 1920s attached rowhouse on 30th Road in Astoria where the homeowner had three previous roofers replace the membrane without fixing the cracked coping cap. Water was traveling down the inside face of the brick parapet and entering the second-floor bedroom two feet from the actual breach. We repointed the parapet, replaced the coping, and installed new modified bitumen with proper counter flashing. The leak stopped. It stayed stopped.

Built-Up Roofing (BUR)

Built-up roofing - the classic “tar and gravel” system - still has a place on Astoria’s older commercial and multi-family buildings, especially where roof traffic is heavy and budgets are tight. A four-ply BUR system with flood coat and gravel surfacing on a 1,500-square-foot Astoria walk-up typically costs $3,200-$5,800. The multiple layers provide redundancy; if one ply is compromised, the others hold. We use Atlas and Owens Corning felts and asphalts, installed hot to ensure proper adhesion between plies. BUR requires skilled labor, which is why we train our apprentices on proper mopping technique and seam staggering before they touch a customer’s roof.

TPO Roofing

TPO - thermoplastic polyolefin - is the fastest-growing flat roof system in Astoria for good reason. The white reflective surface cuts cooling costs on top-floor apartments, and the heat-welded seams create a monolithic membrane without the seams and adhesives that can fail. A TPO installation on a typical Astoria two-family flat roof runs $5,800-$9,400 for a fully adhered system with proper insulation recovery. We install TPO from GAF and CertainTeed, both with manufacturer warranties that require certified installer status - which we hold. TPO’s weakness is poor installation; welded seams done too hot or too cold will fail. Our crews are factory-trained and re-certified annually.

EPDM Roofing

EPDM rubber roofing remains a solid choice for Astoria’s low-slope applications, particularly on detached garages and rear additions where cost matters and aesthetics are secondary. A ballasted or mechanically attached EPDM system on a 400-square-foot garage roof typically runs $2,800-$4,500. The synthetic rubber membrane handles temperature extremes well and repairs easily. We use EPDM from Owens Corning with proper seam tape and primer systems, not the contact-cement shortcuts that fail in Astoria’s humidity.

Solar Ready Roofing

Solar ready roofing in Astoria means building a flat roof system that can handle the dead load of panels, the penetrations of racking systems, and the maintenance traffic that follows. We engineer the assembly from the deck up: proper insulation, a high-PSI membrane rated for foot traffic, and flashing details that accommodate conduit runs without compromising waterproofing. Solar ready installations run $6,500-$11,000 depending on structural reinforcement needs. We coordinate with your solar contractor’s drawings and ensure the roof warranty remains intact after panel installation.

Green Roof Systems

Green roofs are still uncommon in Astoria but growing, especially on new construction and gut renovations in the 11106 waterfront zone. The engineered soil profiles, drainage layers, and root barriers require specialized waterproofing beneath. We install the roofing substrate - typically a hot-applied rubberized asphalt or self-adhering modified bitumen from IKO - and coordinate with landscape contractors for the green roof assembly above. Green roof substrates start around $12 per square foot for the waterproofing layer alone, with full systems running $18-$28 per square foot installed.

Trusted Brands We Service in Astoria

We are authorized installers for seven manufacturer lines: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. For Astoria’s flat-roof market, we stock CertainTeed and IKO modified bitumen rolls, Atlas BUR felts, and Owens Corning TPO and EPDM membranes at our Queens warehouse. That means no waiting three weeks for a special order when your parapet is leaking into the bedroom. Most repairs, we complete in a single visit. The materials on your roof are the materials we specified - no substitutions, no “equivalent” products that don’t match the warranty paperwork.

Common Specialty Roofing Problems We See in Astoria Homes

• Parapet mortar failure misdiagnosed as membrane leaks. On Astoria’s attached rowhouse blocks, the most common misdiagnosis is a “roof leak” that is actually open or failed mortar in the brick parapet or a cracked coping cap. Water travels down the inside face of the parapet and enters the building feet away from the actual breach. Roofers who replace the membrane without addressing parapet masonry will be called back after the next rain. We check the parapet first.
• Freeze-thaw destruction of coping joints and counter flashing. The NYC freeze-thaw cycle - repeated sub-freezing nights followed by daytime thaw from November through March - is particularly destructive to parapet coping joints and roof-to-wall counter flashing. Late-winter leak calls are a predictable seasonal surge in Astoria. We inspect these transitions annually and repoint before the mortar turns to powder.
• Salt-air corrosion on flat-roof-access hardware. Astoria sits close enough to the East River and Upper Bay that elevated ambient humidity accelerates corrosion in metal roof components. Access hatches, ladder rungs, and HVAC platform fasteners rust years faster than inland. We specify stainless steel or hot-dip galvanized hardware for coastal exposures.
• Party-wall flashing complications. Shared party walls between attached buildings create complex flashing transitions that out-of-area roofers often botch. The step flashing must extend properly onto both properties, and the membrane must turn up the wall with a reglet or termination bar - not caulk, not hope. We coordinate with neighboring owners and document the condition of shared walls before we start.
