- Roofing for Putnam's lake country and Hudson Highlands
Roofing Contractor in Putnam County, NY
Roofing services across Putnam County, from the lakes to the Highlands.
Putnam is mostly trees, hills, and water, and the roofs here take a beating because of it. We have roofed the county’s lake communities and Highlands villages for years as part of our tri-state work, so we know what a wooded acre in Putnam Valley, a cottage on Lake Mahopac, or a 19th-century home in Cold Spring actually needs overhead. Whether you are replacing an aging asphalt roof, putting durable standing-seam metal on a home tucked into the woods, or restoring slate on a historic Highlands house, we help you choose the system that fits the home, the setting, and a climate that runs colder and snowier than the counties to the south. From architectural asphalt and metal to cedar, copper, and slate, every roof we install is built to last.

- Why A&J Reliable
Built for Putnam's Woods, Lakes, and Hudson Highlands

Putnam is not subdivisions and sidewalks. It is forest, ridgelines, reservoirs, and lakes, and the roof that survives here is not the same one you would put on a house in the open.
Drive the county and you pass wooded contemporaries on long gravel drives in Putnam Valley and Kent, lake cottages around Mahopac and Lake Carmel that were never built for year-round weather, and the 19th-century homes of Cold Spring, Nelsonville, and Garrison sitting in the Hudson Highlands. Each one sits under different trees, on a different slope, taking a different kind of winter.
A contractor who only roofs flat, open suburban lots will miss what a Putnam home is up against.
We work the other way. A lakefront cottage on Lake Mahopac is not a 19th-century home in Cold Spring. A wooded contemporary in Garrison is not a colonial in Brewster. The right roof starts with the home and the land around it, and we have spent decades roofing exactly these kinds of houses.
That is what Putnam asks for. That is A&J Reliable.
What Putnam does to a roof
- Heavy forest canopy. More than anywhere else we work, Putnam homes sit under mature trees. That means constant shade on north slopes, moss and algae that hold moisture against the roof, gutters and valleys packed with debris, and the occasional limb that comes down hard. Half of what shortens a roof here is the woods around it.
- Snow load and ice dams at elevation. Putnam runs higher and colder than the counties to the south and takes more snow. On older lake homes and rural houses with weak attic ventilation, that snow melts, refreezes, and backs up under the shingles into the ceiling. The cause is almost always ventilation, not the shingle.
- Lake humidity. Homes ringing Lake Mahopac, Lake Carmel, and Lake Peekskill stay damp, and many were built as seasonal cottages and later lived in year-round without the ventilation to match. That moisture finds its way into decking and rafters.
- Wind over the Highlands. Exposed hilltop and ridge homes in Philipstown and Putnam Valley catch wind that lifts shingle edges and drives rain under flashing on the windward face.

What this means for your estimate
We do not price a roof off a photo. On a Putnam home we look at the attic ventilation, the decking under an old roof that may have been on since the house was seasonal, the flashing around additions, dormers, and chimneys, and how the surrounding trees and slope move water and debris across the roof. Permitting runs through your town building department, Carmel, Kent, Patterson, Philipstown, Putnam Valley, or Southeast, and the villages of Brewster, Cold Spring, and Nelsonville. If your home is in the Cold Spring historic district, the review board may weigh in on material and color, and we will tell you what is allowed before you choose. We handle the permitting as part of the job.
- Why A&J Reliable
Four reasons Putnam homeowners trust us with their biggest investment.
More than forty-five years of roofing across New York, New Jersey, and Connecticut, including the wooded and Highlands homes that make Putnam its own kind of job.
- 01 / Expertise
We know the hard sites.
Steep Highlands roofs, lake cottages built for summers and now lived in all year, and homes set deep in the woods. We know the ventilation fixes, the snow-shedding systems, and the durable materials these settings actually call for.
- 02 / Philosophy
We build relationships, not transactions.
In a county this tight-knit, word travels. Much of our work comes from homeowners we roofed before and the neighbors who saw it done right. That is the standard we hold to.
- 03 / Legacy
More than four decades of proof.
Thousands of tri-state homes since 1979. Read the testimonials, check the reviews, or look up at a roof you pass on the way into town. The record says more than any pitch.
- 04 / Materials
Premium products, built to endure.
On remote and wooded homes, durability matters even more. We install only what we would put on our own homes: leading asphalt, metal, copper, and slate systems, chosen for looks, performance, and a long life with little fuss.
- Roofing Materials
ROOFING MATERIALS — Five Systems, One Built for Your Home.
No two Putnam homes are the same. A lakefront cottage on Lake Mahopac, a 19th-century home in Cold Spring, and a wooded contemporary in Garrison ask for very different roofs, budgets, and upkeep. So we help you choose the system that fits both the home and the way you live in it.
- Putnam's Most Popular Roof
Asphalt Roofing Shingles
20-30 Year Lifespan
Architectural asphalt shingles cover most Putnam homes, and for good reason. They handle cold, snowy winters well, come in a wide range of colors and profiles, and offer the best long-term value for most homeowners. Algae-resistant shingles are worth a serious look here, where shade and moisture invite the green streaks you see on so many wooded-lot roofs.
- Built for Snow Country
Metal Roofing
50+ Year Lifespan
Standing-seam metal is a natural fit for Putnam. It sheds snow instead of holding it, stands up to wind on exposed ridges, and lasts for decades with little maintenance, which matters on a home set back in the woods. It also suits the contemporary and lake homes scattered across the county.
- Heritage Appearance
Slate & Synthetic Slate
Exceptional Longevity
The historic homes of Cold Spring and Garrison hold some genuinely fine 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 maintenance. Both reward the right home with decades of beauty.
- Architectural Landmark
Copper Roofing
100+ Year Lifespan
Nothing makes a statement like copper. Favored on historic homes and architectural accents in the Highlands villages, it weathers into a rich patina that only improves with age. Homeowners choose copper for character and craftsmanship as much as protection.
- Authentic Beauty
Cedar Roofing
Naturally Insulating
Cedar suits Putnam’s rustic and wooded homes like little else, weathering into a soft silver-gray that belongs among the trees. For homeowners who want warmth, texture, and real curb appeal, it remains one of the most beautiful roofs available.
- Not sure?

- Recent Roofing Work
See the work, then call us.
My house is surrounded by trees and the roof is always mossy and covered in debris. Can you help?
Yes, and it is the most common issue we see in Putnam. Shade and constant moisture on wooded lots grow moss and algae and pack the valleys with debris. We clean it properly, can install algae-resistant shingles or metal, and set up the roof and gutters to shed what the trees drop.
I keep getting ice dams every winter. Why?
Almost always attic ventilation and insulation, not the shingles, and Putnam’s higher elevation and heavier snow make it worse than down-county. We fix the cause, not just the leak it leaves behind.
My lake house was built as a summer cottage. Is its roof a problem year-round?
Often, yes. Many homes around Lake Mahopac, Lake Carmel, and Lake Peekskill were built seasonally and later lived in all year without the ventilation or insulation to handle winter. We assess what is actually up there and bring it up to a four-season standard.
Do you service homes way out on rural or wooded lots?
Yes. We have roofed Putnam’s rural homes, lake communities, and Highlands villages for years as part of our tri-state work. A long driveway or a wooded acre is not a problem.
My home is in Cold Spring or Garrison and may be historic. Does that limit my options?
It can. The Cold Spring historic district has a review board that can weigh in on roofing material and color, and slate or metal is often the right call on these older Highlands homes. We will tell you what is allowed before you settle on a product.
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 Putnam’s cold, snowy winters, and with so much shade and moisture from the trees, proper installation and ventilation drive 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.
