Rockzen coordinates roof installation with building schedules. Our team works with your general contractor to keep the project on track. Every install matches architect drawings and DOB-approved plans.
Rockzen offers free consultations for new construction and building addition projects. Every consultation includes system recommendations, cost estimates, and timeline projections.
Rockzen provides ten roof installation services for NYC residential, commercial, and mixed-use new construction. Licensed contractors handle every install from deck preparation through final DOB inspection.
Rockzen installs new flat roofs using TPO, EPDM, or modified bitumen membranes. Commercial buildings often use white TPO for energy performance. Every install includes tapered insulation for proper drainage slope.
Rockzen installs sloped roofs using asphalt shingles, metal panels, or slate. Brownstones and single-family homes need proper ice and water shield installation. Attic ventilation prevents winter ice dam formation.
Rockzen installs commercial roofing for office buildings, retail, and industrial properties. Systems include single-ply EPDM, TPO membrane, and built-up roof assemblies. Commercial installs handle HVAC equipment loads and rooftop foot traffic.
Rockzen installs TPO using heat-welded seams for watertight joints. White TPO reflects summer heat and can reduce cooling costs measurably. Every install includes proper flashing at parapet walls and penetrations.
Rockzen installs EPDM rubber roofing for residential and commercial flat roofs. Systems use mechanical fasteners or fully-adhered methods. Ice dam prevention includes insulation upgrades and continuous air sealing.
Rockzen installs architectural asphalt shingles on NYC brownstones, rowhouses, and single-family homes. Every install includes underlayment, ice and water shield, and proper attic ventilation. Historic properties may need landmark approval.
Rockzen installs standing seam and corrugated metal roofs. Metal roofing sheds snow to help prevent ice dam formation. Snow retention systems protect pedestrians from sliding snow on steep roofs.
Rockzen installs green roofs and rooftop decks with full waterproofing. Every green roof needs structural load analysis to confirm capacity. Penthouse terrace waterproofing protects the occupied space below.
Rockzen installs skylights, roof hatches, and mechanical penetrations. Curb flashing details prevent water entry around openings. Copper flashing provides long-term durability on premium installs.
Rockzen installs interior drains, scuppers, and overflow protection. Every drainage design follows proper slope calculations. Systems help prevent standing water beyond 48 hours after rainfall.
Here’s how Rockzen runs the whole install from plan review to final DOB sign-off. Every step meets NYC Building Code and manufacturer specifications.
Rockzen reviews your building plans against NYC energy code. We analyze roof load capacity and drainage design. We check the parapet coping needs at the same time. We help you pick a system that fits your budget and lifespan needs.
Rockzen submits new building permits to NYC DOB using your architectural drawings via DOB NOW. Submissions cover insulation R-value (thermal resistance rating), membrane type, and flashing details. At this stage, we handle scaffolding and safety net approvals. This keeps your build on schedule.
Rockzen verifies the roof deck supports the full roof assembly. The contractor confirms the drainage slope before the insulation is installed. Low-slope insulation installs over the deck. A vapor retarder blocks moisture from moving through the assembly. Continuous insulation reduces thermal bridging. This means less heat escapes through structural parts. It also meets NYC energy code requirements. At this stage, the team designs proper roof ventilation.
Rockzen installs the vapor barrier to block interior moisture from reaching the insulation. Placement depends on your building’s cold roof or warm roof design. Membrane underlayment provides secondary waterproofing before the primary membrane goes on. Ice and water shield installs at eaves and valleys to help prevent ice dam damage.
Rockzen installs the membrane using the right method for your system. Workers heat-weld seams in TPO to create permanent watertight joints. EPDM installs fully-adhered (glued to substrate) or mechanically-fastened. Modified bitumen goes torch-applied or cold-applied based on fire safety needs. Asphalt shingles install with proper alignment and starter courses on sloped roofs.
Rockzen installs flashing at parapet walls, skylights, and every roof penetration. Copper flashing on premium installs for long-term durability. Scuppers, drains, and overflow protection help prevent ponding water. Installers place drip edge and gutters at the roof perimeter to direct water off the roof.
NYC DOB inspectors verify the install meets approved plans and Building Code. Rockzen coordinates the inspection and addresses any items the inspector flags. Certificate of Occupancy gets issued once the roof passes inspection. See our roof repair services for post-install maintenance and warranty coverage details.
New NYC buildings use seven main roofing systems. Each fits different building types and performance needs.
White single-ply membrane heat-welded at seams. Reflects heat and can reduce cooling costs. Meets NYC energy code reflectance requirements. Lasts 15 to 25 years.
Black rubber membrane mechanically fastened or fully adhered. Handles freeze-thaw cycles well. Absorbs more heat than TPO but costs less. Lasts 20 to 30 years.
Layered asphalt torch-applied or cold-adhered. Handles foot traffic and rooftop equipment better than single-ply. Two-ply systems last 15 to 20 years. Cold-applied removes torch safety concerns.
Architectural shingles on brownstones, rowhouses, and single-family homes. Better wind resistance than three-tab styles. Lasts 15 to 25 years with proper ventilation.
Standing seam panels or copper roofing on commercial and residential. Sheds snow to help prevent ice dams. Concealed fastener systems remove exposed screw weathering. Lasts 40 to 60 years.
Vegetation over waterproofing membrane. Manages stormwater runoff. Extensive systems support sedum with minimal maintenance. Intensive systems allow rooftop gardens with deeper soil.
Many asphalt layers with reinforcing fabric. Gravel ballast protects the top surface. Durable but heavy and needs strong structural support. Lasts 20 to 30 years.
Every install includes several components working together:
