Roof Replacement for Nassau Homeowners
If your Nassau County home needs a new roof — whether from storm damage, age, or years of wear from Long Island’s coastal weather — you need a contractor who can deliver quality work fast.

That’s why County Roofing Systems provides full roof replacement services to homeowners and businesses throughout Nassau County.
Our team handles every aspect of roof replacement, from minor residential capes in Levittown to large colonial homes along the North Shore.

Professional Roof Replacement Services in Nassau County
As a local roofing contractor serving Nassau County and the surrounding Long Island area, we understand the specific challenges roofs face here.
Salt air along the South Shore, freeze-thaw cycles, and Nassau County’s large stock of postwar homes all contribute to roof deterioration at a faster rate than many homeowners expect.

We work with all roof types, including:
- Asphalt shingle roofs
- Flat and low-slope roofing systems
- Residential and light commercial properties
- Cape Cod, colonial, ranch, and split-level home styles
Roof Replacement Services In Nassau County
We offer comprehensive replacement solutions tailored to your home’s specific conditions.
TEAR-OFF
Full Tear-Off and Replacement
We remove your existing roofing system down to the deck, inspect and repair any damaged sheathing, install proper underlayment and ice-and-water shield — critical for Nassau County’s freeze-thaw cycles — then lay a complete new roofing system from drip edge to ridge cap.
This is the right approach for roofs at or near the end of their service life, which describes a significant portion of Nassau County’s postwar housing stock.
ROOF OVERS
Roof-Over Installation
In situations where the existing layer is structurally sound and local code allows, a roof-over can be a faster, more cost-effective option.
We assess your specific situation honestly and recommend only what your home actually needs.
FLAT AND LOW-SLOPE
Flat and Low-Slope Roof Replacement
Many Nassau County homes — particularly capes with garage additions and ranches with rear extensions — include flat or low-slope roof sections.
We replace these using membrane systems designed for Long Island’s temperature swings and precipitation levels.
EMERGENCY SERVICES
Emergency Roof Replacement
When a roof has failed to the point of active water intrusion or structural compromise, we respond promptly- stabilizing the situation immediately and completing the permanent replacement as quickly as scheduling allows.

Signs Your Nassau County Roof Needs Replacement
Many homeowners don’t realize their roof is failing until the problem is already serious. Here are the most common indicators:
- Roof age exceeding 20–25 years: especially relevant given Nassau County’s large concentration of homes built between the 1940s and 1970s
- Multiple shingle layers already installed, common in older Nassau homes where previous contractors skipped tear-offs
- Widespread granule loss visible in gutters or at downspout bases
- Sagging or soft spots on the roof surface indicating damaged decking below
- Persistent leaks that return after repairs, suggesting systemic failure rather than isolated damage
- Visible daylight through attic boards when viewed from inside
- Curling, buckling, or missing shingles across large sections of the roof
- Increased energy bills caused by compromised attic ventilation: a common symptom in Nassau County’s older cape-style homes
If you notice any of these issues, act quickly. Deferred replacement typically means water damage to decking, rafters, and interior finishes that significantly raises the total cost of the project.

County Roofing replaced my aging roof and all of the gutters. Keith was truly professional, performing the estimate, supervising the work, and keeping me informed at every step. The results were beautiful. I would not hesitate to recommend County Roofing Systems to anyone.
Our roof was a bit of a tricky project, but Keith’s crew handled every nuance flawlessly—right down to protecting the gutters and surrounding landscaping. The workmanship is top-tier; you can see and feel the quality in every shingle. Equally impressive, Keith was completely transparent about costs and timelines, and his quote was the most competitive we received by a mile.
I had County Roofing Systems install new vinyl siding and gutters and leaders. Keith was very professional as well as personable and really knew his craft. Keith was on site the entire time with his crew. The house came out perfect. Just want to say thanks to Keith and I would give 5 stars plus! Thanks again Keith for all your good work.
Had a fantastic experience with County Roofing! Keith was extremely thorough. He walked through every detail, explained all the color options, and offered thoughtful recommendations that made a big difference. His crew did an outstanding job, and our new roof looks absolutely amazing.
Highly recommend County Roofing to anyone looking for a reliable, skilled roofing team!
Recently had a new roof done by County Roofing, and am so thankful for having met Keith. He is fair with the price, knowledgeable about his work, patient, responsive and professional. It really was a pleasure, and I will definitely be recommending Keith and his crew to anyone I know looking to do roof work.
