Torch-Down & Silicone Systems for North Jersey Flat Roofs

Flat roofing is where we built our name. For North Jersey's row houses, multi-family buildings, and low-slope commercial roofs, we install two proven systems engineered for our freeze-thaw cycles, summer rain, and ponding water.

Firestone · Modified Bitumen

Torch-Down Roofing

A multi-ply SBS modified bitumen system heat-welded directly to the substrate. Creates a fully bonded, monolithic membrane that resists tearing, punctures, and foot traffic — ideal for urban roofs that double as access surfaces.

  • 20+ year service life
  • Multi-ply puncture resistance
  • Walkable surface
  • Heat-welded watertight seams
Torch-Down Details →

Tri-Built 985 · Silicone Coating

Silicone Roof Coating

High-solids silicone seals leaks, reflects heat, and adds a decade of waterproof service life — with renewable surface technology. Holds up where acrylics fail: doesn't wash off in standing water, doesn't chalk in UV.

  • Renewable surface system
  • Reflective Energy Star finish
  • Ponding-water resistant
  • Restores roofs without tear-off

Shingle Roofing

Architectural Shingle Replacement Done Right

On pitched roofs, we install premium architectural shingles from the manufacturers homeowners know. Every shingle replacement is full tear-off — no overlays, no shortcuts, no nail-gun cheats.

Service Life

Every replacement includes the full system — not just the visible shingles:

  • Full tear-off to decking
  • Rotted sheathing replacement
  • Ice and water shield (eaves & valleys)
  • Synthetic underlayment
  • New drip edge & ridge ventilation
  • Matching ridge cap shingles

A shingle roof installed properly should last 25–30 years — and ours do. Every install includes a written workmanship warranty on top of the manufacturer’s coverage, plus a final inspection Damian walks personally.

Where We Work

Serving Hudson County, NJ

We serve homeowners, landlords, and business owners across Hudson County and the surrounding North Jersey area. We know these neighborhoods — the row-house flat roofs, the older shingled two-families, the mixed-use commercial buildings — and we price every project honestly based on what the roof actually needs.

Free Roof Evaluation · No Pressure, No Obligation

Every roofing project starts with a free, no-pressure evaluation. We climb the roof, photograph what we see, and walk you through options in plain English.

  • Torch-down vs. silicone recoat — which makes sense for your roof
  • Full shingle replacement vs. targeted repair
  • What your insurance should or should not cover
  • Written estimate with scope, materials, and warranty spelled out
