- Rockland County's hometown roofer, based in Nanuet
Roofing Contractor in Rockland County, NY
Roofing services across Rockland County, run from our shop in Nanuet.
We are not a roofing company that drives into Rockland for the day. Our shop is here on Second Avenue in Nanuet, and the crews who roof these towns live in them. Whether you are replacing a tired asphalt roof, restoring a slate Victorian near the river, or topping a newer home, we help you choose the roof that fits your house, your budget, and the way Rockland weather actually behaves. From architectural asphalt and standing-seam metal to cedar, copper, and slate, every roof we install is built for Hudson Valley winters and made to last.

- Why A&J Reliable
A Rockland Roofer That Actually Lives Here

The houses in Rockland do not share one style, and they should not share one roof.
Drive from the riverfront Victorians of Nyack and Piermont, through the postwar colonials, ranches, and split-levels of New City, Pearl River, and Nanuet, and out to the wooded homes tucked against the Ramapos in Suffern and Sloatsburg, and you pass a century of building styles in twenty minutes. Each one wants something different overhead.
A contractor who puts the same system on all of them can quietly cost a homeowner curb appeal and years of roof life.
We work the other way. A riverfront Victorian in Nyack is not a raised ranch in New City. A 1960s split-level in Pearl River is not a new build in Montebello. The right roof starts with the house underneath it, and after more than four decades working out of Nanuet, we know these houses.
That is local. That is Rockland. That is A&J Reliable.
What Rockland does to a roof
- Snow load and ice dams. Rockland sits inland, and the western, higher-elevation towns near the Ramapos catch real snow. Pair that with older homes short on attic insulation and ventilation, and meltwater backs up under the shingles and into the ceiling below. More often than not the cause is ventilation, not the shingle.
- River-valley moisture. Homes along the Hudson and in the shaded hollows below Hook Mountain and the Palisades ridge stay damp. North-facing slopes grow moss and algae, and trapped moisture shortens the life of a roof that was not installed with it in mind.
- Heavy tree cover. The woodlands through Tallman, Montebello, and Suffern are part of why people love western Rockland, and also why limbs fall, gutters fill, and debris holds water against the roof and in the valleys.
- Wind and wind-driven rain. Storms tracking up the river corridor and over exposed ridges around Pomona and Mount Ivy push rain sideways, and it finds every loose flashing and tired seam.

What this means for your estimate
We do not price a roof off a photo. On a Rockland home we look at the attic ventilation, the condition of the decking under that twenty-year-old asphalt, the flashing around the additions, dormers, and chimneys these homes pick up over the years, and what your town will require before a single shingle is ordered. Permitting runs through Clarkstown, Ramapo, Orangetown, Haverstraw, or Stony Point depending on where you live, and we handle that paperwork as part of the job.
- Why A&J Reliable
Four reasons Rockland homeowners hand us their biggest investment.
More than forty-five years of residential roofing across New York, New Jersey, and Connecticut, run from a shop right here in Rockland, and built around the families living underneath.
- 01 / Expertise
Specialists, not generalists.
Decades on the exact houses Rockland is built from: the steep Victorian roofs along the river, the suburban re-roofs inland, and the ventilation corrections older homes here actually need.
- 02 / Philosophy
We build relationships, not transactions.
Most of our Rockland jobs are a short drive from the last one, earned from homeowners we roofed years ago and the neighbors who watched us work. That is the standard we hold to.
- 03 / Legacy
More than four decades of proof.
- 04 / Materials
Premium products, no compromises.
- Roofing Materials
ROOFING MATERIALS — Five Systems, One Built for Your Home.
No two Rockland homes are the same. A Victorian in Nyack, a raised ranch in New City, and a new build in Montebello carry different styles, budgets, and expectations. So we help you choose the system that fits both the house and the way you plan to live in it.
- Rockland's Most Common Roof
Asphalt Roofing Shingles
20-30 Year Lifespan
Architectural asphalt shingles cover more Rockland homes than anything else, and for good reason. They handle Hudson Valley weather well, come in a wide range of colors and profiles, and deliver the strongest long-term value for most homeowners. On a typical New City or Pearl River home, a premium asphalt roof hits the right balance of looks, performance, and price.
- Modern Performance
Metal Roofing
50+ Year Lifespan
Standing-seam metal brings clean lines, long life, and excellent snow-shedding, which earns its keep through a Rockland winter. It suits contemporary homes, farmhouses, and custom builds, standing up to hard weather while giving a home a distinct profile.
- Heritage Appearance
Slate & Synthetic Slate
Exceptional Longevity
Rockland’s river villages hold some of the area’s finest slate roofs. We restore natural slate where the history is worth keeping, and install premium synthetic slate where homeowners want the same look with less weight and upkeep. Both reward the right home with decades of beauty.
- Architectural Landmark
Copper Roofing
100+ Year Lifespan
Nothing makes a statement quite like copper. Chosen for historic homes, accents, and standout architecture, it weathers into a rich patina that only improves with age. Homeowners pick copper for character and craftsmanship as much as protection.
- Authentic Beauty
Cedar Roofing
Naturally Insulating
Cedar offers a warmth and texture no manufactured product copies, weathering into a soft silver-gray that suits Rockland’s older and period homes. For owners who want authenticity and curb appeal, it remains one of the most beautiful roofs available.
- Not sure?
Which Roofing Material Is Right for Your Home?

Do I need a permit to replace my roof in Rockland County?
Yes. A roof replacement needs a permit, and the rules vary by town: Clarkstown, Ramapo, Orangetown, Haverstraw, and Stony Point each run their own building department. We pull the permit as part of the job and know these offices well after decades working out of Nanuet.
I get ice dams every winter. Why?
Almost always attic ventilation and insulation, not the shingles, and the higher western towns near the Ramapos see it most because they catch the most snow. We fix the cause, not just the leak it leaves behind.
My house backs up to the woods and the roof always looks green. Can you fix that?
Yes. Shaded, north-facing slopes in Rockland’s wooded and river-valley neighborhoods grow moss and algae that hold moisture against the roof. We clean it properly and can install algae-resistant systems so it does not come back as fast.
My slate roof is leaking. Do I have to replace the whole thing?
Not necessarily. Slate on the older Nyack and Piermont homes can last a century, and targeted restoration is often the right call. We will tell you honestly whether it is worth saving or whether synthetic slate is the smarter long-term move.
Are you actually local, or do you just service the area?
We are based in Rockland. Our shop is at 50 Second Ave in Nanuet, and we have worked out of the county since 1979. When something goes wrong, you are not waiting on a crew driving up from out of the area.
How long will a new roof last here?
Architectural shingles run about 20 years, metal a century or more, and copper and slate longer still. In Rockland’s freeze-thaw winters, proper installation and ventilation matter as much as the material for how long you actually get.

We purchased the Gutter Topper in 2018, after my father recommended A&J Reliable as they installed Gutter Topper on his home. Matthew was very friendly and informative regarding the products, installation, & free future maintenance needs. I emailed A&J about some debris on the gutters. They called within a few days to schedule a maintenance cleaning. The men arrived as discussed and cleaned the debris in a timely manner. No cost for these cleanings. Thank you A&J Reliable and your team. Highly recommend.Posted on Patricia MerrittTrustindex verifies that the original source of the review is Google. We have been clients of A&J for decades. We were among the first to get leaf guards installed and were so glad we did. They come when they say they will and do great work. We now use them to blow off debris from our roof tops which get covered with needles in the fall. It continues to be a well-run operation.

Explained everything necessary and arrived when scheduled.
