In the 18th century this area was home to farmers and small fishermen. Today Port Jefferson connects Long Islanders to the Bridgeport ferry and the Long Island Railroad. But it still maintains its small town charm, with many historical homes and buildings. 

But while the North Shore is beautiful, the sea climate can be hard on roofs. Gales and nor’easters tear at your roof. Asphalt shingles bake in the blistering sun.  Heavy snows strain your roof frames. When you live in Port Jefferson, you need a good roofing contractor. And that means you need County Roofing Systems. 

For over 35 years, County Roofing Systems has been taking care of roofs in Port Jefferson and Suffolk County.  Our team is experienced with all types of roofing material and with commercial and residential roof replacement and roof repair work. We can handle everything from roof leaks to a complete roof installation. 

A new roof can not only make you old house look like a brand new home. It can also save you money on your energy bills. Today’s roofing products offer better insulation, fire resistance, and durability. Because we’re a certified CertainTeed SELECT Shingle Master, we can offer the best warranties in the roofing industry.  And we can even help you with financing.  

0% Financing Available for Roof Replacement or Repair

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. We’ve worked with many local Suffolk County lenders who will be happy to finance your needed roof work.

We also have long relationships with many roofing product suppliers. We get special prices and bulk discounts on materials and pass that savings down to you. We use high-quality supplies, but our prices are reasonable. Your new roof may be more affordable than you expect, and that’s not even counting the savings on your utility bills.

Let County Roofing Systems Cover Your Port Jefferson Building


We can handle any roof repair large or small. Our team has worked on roofs across Long Island. We’ve handled steep slope roof projects for churches, flat roof jobs for multifamily buildings, and roof leak repairs for first-time homeowners. 

Some roofing contractors will fix the immediate issue without checking for underlying damage. We make sure that every problem is solved before we leave the job site. We know that a patched leak can cover up a soggy roof deck that might rot if simply covered over with sealant.

If we find underlying problems, we will give you an itemized list of every problem. We will also tell you how we plan to fix the issue, complete with all materials and labor involved. 

County Roofing Systems working on rainy day


You can expect minor repairs to your roof on occasion. But if you are constantly plugging leaks, it may be time to consider a roof replacement.

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.  

A Better Looking Designer Roof System

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 architectural shingles make your house stand out on the block. They’re the most beautiful and most durable shingles on the market. And the CertainTeed Integrity Roof System gives you a roof that will last for decades without giving you trouble. A CertainTeed roof is a great and cost-effective way to make your older Port Jefferson house look like a brand new home.

CertainTeed’s Belmont luxury roofing shingles mimic the classic charm of slate tile for timeless strength and beauty. But unlike traditional slate, Belmont requires minimal upkeep, giving it an effortless beauty.

CertainTeed’s Carriage House laminated shingles mimic the look of scalloped natural slate or wood shake roof tiles. But they offer the durability and easy maintenance of asphalt shingles, with a variety of vibrant shingle color options.

Presidential Shake Roof in Country Gray
