SERVING LONG ISLAND AND NY FOR 35 YEARS

Install Your New Roof Right In Suffolk

A properly installed roof is one of the most important investments a Suffolk County homeowner can make.

Whether you’re building new construction, replacing a failed system, or adding a roof to a home addition or dormer, the quality of the installation determines how long that roof performs.

County Roofing Systems — based right here in Melville — provides expert roof installation services to homeowners throughout Suffolk County’s diverse communities, from Huntington to Southampton and everywhere in between.

We’ve been installing roofs on Long Island for over 35 years. We understand the conditions Suffolk County roofs face: South Shore salt air, East End coastal exposure, heavy snowfall in northern communities, and the freeze-thaw cycles that test every component of a roofing system every winter.

A BEAUTIFUL NEW ROOF

New Construction Roof Installation

We work with homebuilders and homeowners on new construction projects throughout Suffolk County, installing complete roofing systems from decking preparation through final ridge cap. Every installation begins with proper underlayment and ice-and-water shield placement — essential in Suffolk County, where wind-driven rain and ice damming are consistent seasonal threats.

ADDITIONS

Home Addition and Dormer Roofing

Many Suffolk County homeowners expand their homes with second-story additions, dormers, or rear extensions. These projects require careful integration between new and existing roofing to prevent future leaks at transition points. We handle the full installation, ensuring flashing and valley details are done correctly the first time.

FLAT ROOF INSTALLATION

Flat and Low-Slope Roof Installation

Ranch-style homes are common throughout western and central Suffolk County, and many include flat garage roofs or rear additions. We install membrane roofing systems appropriate for Long Island’s climate, including TPO and modified bitumen systems designed for temperature fluctuations and standing water resistance.

STRUCTURAL REPAIRS

Structural Decking Repairs

Before laying any new roofing material, we inspect the decking for rot, water damage, or structural weakness — issues we find regularly in Suffolk County homes built in the 1960s and 1970s. Any compromised sections are replaced before installation proceeds.

Signs You Need a New Roof Installation

  • Your current roof is 20+ years old and showing widespread deterioration
  • You’ve had repeated repairs that aren’t holding — a sign the system itself has failed
  • You’re building an addition or dormer that requires new roofing
  • Your existing shingles are curling, buckling, or shedding granules heavily
  • There are soft spots or visible sagging on the roof plane
  • You’re seeing moisture stains on ceilings or attic sheathing
  • Storm damage has compromised enough of the roof that full installation is more practical than repair
  • You’re preparing to sell and the current roof’s condition will affect the transaction
  • Your energy bills are rising and poor attic ventilation is the suspected cause — common in Suffolk County’s older ranch-style homes

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.
