A roof leak doesn’t stay small. What starts as a ceiling stain after a storm can turn into mold, rotted decking, and a much bigger bill by the time spring arrives. North Great River homeowners deal with this more than they should not because their roofs are poorly built, but because the South Shore weather is genuinely hard on them. Wind off the Great South Bay, salt air year-round, and nor’easters from October through March put real stress on every shingle tab, every flashing joint, and every ridge cap on your home.
Most homes in North Great River were built between the 1950s and 1970s. That means the flashing around your chimney or dormer might be original, or close to it. The underlayment underneath your current shingles could be decades old. When a roof that age meets South Shore weather, the failure points are predictable and a contractor who only addresses what’s visible on the surface is setting you up for the same call next season.
When the repair is done right, you stop thinking about your roof. No more checking the ceiling after every storm. No more wondering if that stain is getting bigger. That’s the actual outcome not just a fixed shingle, but the confidence that comes with knowing the cause was addressed, not just covered up.
Home Team Construction is a family-owned exterior contractor based in Suffolk County, and we’ve been working on Long Island roofs for over ten years. We carry a valid Suffolk County Home Improvement Contractor license one that requires passing a county exam, not just filing paperwork and every person who shows up to your home is a trained employee, not a subcontractor brought in for the day.
We serve North Great River, East Islip, Great River, and the entire Town of Islip. We know how the weather behaves down here near the bay. We know what the Town of Islip Building Department requires for permitted work. And we know what’s typically hiding underneath the shingles on a 1960s ranch-style home that’s been re-roofed once or twice already.
Alban, the owner, is personally involved in the jobs we take on. That’s not a talking point it’s how the business has operated since day one, and it’s why customers in North Great River and the surrounding area keep calling us back.
It starts with a real inspection, not a quote from the driveway. We get on the roof, document what we find with photos and video before we touch anything, and walk you through what’s actually causing the problem. You’ll see the failed flashing, the lifted shingles, the soft spot in the decking whatever is there. No vague descriptions, no mystery. Just a clear explanation of what needs to happen and why.
From there, you get an itemized estimate with everything included materials, labor, and debris removal. No line items that appear after we’ve already started. If we find something additional once we’re into the work, we show you the photos, explain the situation, and give you a revised number before we proceed. Your decision, always.
If the scope of work requires a permit through the Town of Islip Building Department, we handle that process. Once the job is complete, you get final documentation showing the finished repair. For homeowners dealing with storm damage, we assist with insurance documentation as part of the job not as an add-on. By the time we’re done, you know exactly what was done, why it was done, and what it cost.

Roof repair in North Great River isn’t one-size-fits-all. Salt air off Nicoll’s Bay corrodes metal flashing faster than it would on a home ten miles inland. Ice dams form more frequently in the older ranch-style and hi-ranch homes that make up most of this neighborhood, because the attic insulation and ventilation in homes built before 1975 often doesn’t meet modern standards. These aren’t edge cases they’re common, and they affect what a proper repair actually involves here.
The repairs we handle include roof leak diagnosis and repair, missing or damaged shingle replacement, flashing repair and replacement at chimneys, dormers, and skylights, flat roof repair, ice dam damage repair, and emergency weatherproofing after storm events. Every repair includes a full inspection of the surrounding area not just the obvious damage point because in a home this age, one failure is rarely the only one.
We also offer 24/7 emergency roof repair response throughout North Great River and the surrounding Islip area. If a storm comes through and you’ve got active water intrusion, you don’t have to wait until Monday. We respond fast, stop the immediate damage, and schedule the permanent fix. That’s the whole job not half of it.
The honest answer is that it depends on what’s actually causing the problem. A straightforward shingle repair or minor flashing fix might run a few hundred dollars. A repair that involves replacing damaged decking, addressing ice dam damage, or re-flashing a chimney on an older home can run $1,500 to $3,500 or more depending on the scope. Most homeowners in North Great River are dealing with homes built in the 1960s or 1970s, and those properties often have layered repair histories that affect what a proper fix actually requires.
What we can tell you is that the estimate you get from us is the number you pay. We don’t quote low to get the job and then discover problems once we’re already on your roof. If we find something during the inspection that changes the scope, we show you the photos and give you a new number before any additional work begins. There are no fees for materials like underlayment or plywood that suddenly appear on the final invoice.
For a full roof replacement, yes a building permit through the Town of Islip Building Department is required. For repairs, it depends on the scope. Minor repairs like replacing a few shingles or fixing a small flashing section typically don’t require a permit. Work that involves replacing structural deck boards, making changes to the roofline, or installing a skylight will require one.
This is worth paying attention to, because unpermitted work can create real problems when you go to sell your home or file an insurance claim. A licensed contractor handles the permit process for you it’s part of the job. If you’ve had work done in the past and you’re not sure whether it was permitted, that’s worth looking into before the next project. The Town of Islip’s building department is accessible and the permit history on your property is a matter of public record.
The most common culprits in North Great River’s housing stock are flashing failures and aging underlayment. Flashing the metal that seals the joints around chimneys, dormers, vents, and skylights is the first thing to fail in a coastal environment. Salt air accelerates corrosion, and flashing that might last 20 years inland can start failing in 10 to 15 years in a bay-adjacent community like North Great River. If your home is more than 20 years old and the flashing has never been replaced, it’s worth having it assessed.
Underlayment is the second major factor. Most homes in this area that were re-roofed in the 1980s or 1990s have underlayment that is now 30 to 40 years old. It becomes brittle, develops cracks, and stops functioning as a water barrier well before the shingles above it show obvious wear. That’s why a roof can look okay from the street and still be letting water in the failure is happening underneath the surface layer, not on top of it.
An ice dam forms when heat escapes through your roof deck, melts the snow sitting on your roof, and that water refreezes when it hits the cold overhang at your eaves. The ice builds up and creates a barrier that forces water backward under your shingles. From there, it works its way into the structure showing up as ceiling stains, peeling paint, or mold, often weeks after the original storm.
This is a recurring issue in North Great River specifically because the ranch-style and hi-ranch homes that dominate this neighborhood were built before modern energy codes required adequate attic insulation and ventilation. Poor attic ventilation means heat escapes through the roof deck, which is the root cause of the problem. Removing the ice is a temporary fix. The permanent solution involves addressing the attic conditions that allowed the dam to form in the first place better insulation, proper ventilation, and ice and water shield at the eaves. We diagnose the full picture, not just the visible damage.
The general rule is that if the damage is isolated a section of failed flashing, a few missing shingles, a single leak point repair is usually the right call. If the damage is widespread, if the shingles are losing significant granule coverage across most of the roof, or if the decking has widespread soft spots or rot, replacement makes more financial sense than patching multiple areas over multiple seasons.
For homes in North Great River that were built in the 1950s through 1970s and have already been re-roofed once, the honest answer is that a thorough inspection is the only way to know for sure. We don’t quote replacement when repair will do the job. But we also won’t patch a roof that’s at the end of its useful life and tell you it’s fine because it’s not, and you’ll be calling again within a year. The inspection we do before any work starts is specifically designed to give you an accurate picture of what you’re actually dealing with.
Start with the Suffolk County contractor license database it’s publicly accessible and takes about two minutes to check. Suffolk County requires Home Improvement Contractors to pass a county-administered exam to get licensed, which is a higher bar than most New York counties set. If a contractor can’t give you a Suffolk County HIC license number, that’s a real problem, and it’s worth walking away regardless of how low the quote is. Unlicensed work can void your homeowners insurance coverage and create serious complications when you sell your home.
Beyond licensing, ask who is actually doing the work. A lot of contractors in this area especially after a major storm brings out-of-area operators into the market use subcontractors who have no direct accountability to the company you hired. Ask specifically whether the crew is employed by them or subcontracted. Ask for a written, itemized estimate before any work starts. And if a contractor won’t get on the roof to inspect before quoting, that’s a sign the estimate isn’t based on what’s actually there. North Great River homeowners have been in their homes long enough to know when something doesn’t add up trust that instinct.
