When you live in Port Jefferson Station, you’re never far from the LIRR stop. It’s a great town for people who need easy access to the city and the North Shore beaches. 

But Long Island weather can wear down asphalt shingle roofs. Gales and nor’easters damage shingles. Ice storms and heavy snows can tear down gutters and warp roof decks. The summer sun dries out shingles and fades their once-bright colors.

Port Jefferson homeowners need the best Nassau County roofing company they can find. And that means they need County Roofing Systems. 

Our expert team of professional roofers has experience on all types of roofs. We do the job right the first time and we work with the highest-quality roofing products. Whether you need a roof repair or a complete roof replacement, County Roofing Systems can help give you the roof of your dreams.

We know that financing a home improvement project can be enormously stressful. That’s why we work with you to find financing at the best possible rates. In over 35 years as a Long Island roofing contractor, we’ve worked with many local lenders who finance roof work. They will be happy to support your roofing project.

A County Roofing Systems roof replacement costs less than you might expect. We get bulk pricing deals from many of the best roofing manufacturers, then pass the savings down to you. Hiring the best roofing contractor saves you money in the long term.

County Roofing Systems working on rainy day


People delay roof work because they are worried about the cost. But ignoring a roof leak can magnify the final expense. A small roof leak can lead to water damage, damaged shingles or a rotted roof deck. What could have been a quick fix winds up an expensive roof replacement.

We can replace damaged shingles and patch leaks at the source. We check to see that your roof deck is intact and fix any tears to the roof membrane. We can also repair problems with gutters, fascias, and soffits.

We not only fix the immediate leak. We check to make sure that there are no underlying problems. If we find that your leak has led to seepage or wet roof insulation, we’ll tell you exactly what’s wrong. Then we’ll provide an itemized estimate of the work required.

We keep your gutters clear so water can flow from your roof through the downspout to the ground. Clogged gutters can cause ice dams in the winter and lead to roof deck damage after heavy rains.

We also check and repair damaged or poorly installed roof flashing on your roof. Flashing leaks are a major cause of roof leaks, and can be bent or damaged by windstorms or by careless roofers. We can save you costly water damage and spot damage inexperienced contractors might miss.

We can also wash your roof to remove algae stains. This prevents shingle damage and increases your home’s curb appeal. Regular roof maintenance can save you money in the long term.

Belmont Black Granite


If your roof is over 25 years old, it may be time for new roof. A full roof replacement gives you all the benefits of modern roofing technology. Modern roofing materials are not only more durable, they’re also more energy-efficient. Your new roof can save you money on utility bills and will hold its vibrant colors for decades.

A warped or rotted roof deck or extensive shingle damage may require a full roof replacement. We install new roofs using the CertainTeed Integrity Roof System. That means you get the most durable, energy-efficient, beautiful roof available for your home.

CertainTeed’s architectural shingles can make your house stand out on the block. They mimic the look of a wood shake or slate roof at a fraction of the cost per square foot, and offer easier maintenance. And because they offer better insulation than older shingles, you will save money on your utility bills.

A new roof is one of the most cost-effective home improvement projects and has one of the highest long term ROI values.  


Make Your Neighbors Jealous

Most residential roof installations in Long Island use GAF shingles or Owens Corning shingles. Both GAF and Owens Corning make excellent roofing materials. But at County Roofing Systems, we prefer CertainTeed designer shingles.

CertainTeed’s shingles are the most beautiful and most durable shingles on the market. A CertainTeed roof is a great and cost-effective way to make your older Manhasset house look like a brand new home.

We’re proud to be a certified CertainTeed SELECT Shingle Master. Only the top 1% of roofing contractors can qualify for that certification. We can get you the best warranties in the roofing business. And we can install the CertainTeed Integrity Roof System, the best roofing system available, to CertainTeed’s exacting standards.
