When a nor’easter comes through and shuts down the LIE, your roof is dealing with 40–65 mph sustained winds, wet snow, and freeze-thaw cycling all at once. If the shingles are 20-plus years old, or if the flashing around your chimney or skylights was never done right to begin with, that storm isn’t just an inconvenience it’s the beginning of a water damage problem that gets more expensive the longer it sits.
Commack’s housing stock makes this more urgent than most people realize. The median construction year here is 1964, which means a huge portion of the homes on Burr Road, Kings Park Road, Vanderbilt Parkway, and throughout the Candy Section are on their second or even third roof and many of those replacements are now well past their useful life. On Long Island, asphalt shingles typically last 15 to 20 years, not the 25 to 30 you might see quoted for inland climates. The combination of nor’easters, summer convective storms, and ice dam conditions shortens that window significantly.
What changes after a proper replacement isn’t just the roof. It’s the water stains that stop spreading across your ceiling. It’s the heating bill that stabilizes because the attic is finally ventilated the way it should be. It’s the home inspection that doesn’t flag a failing roof when you’re ready to sell and in a school-district-driven market like Commack, that matters more than most people account for until it’s too late.
Home Team Construction is a family-owned exterior contractor based in Mastic, Suffolk County. For over 10 years, we’ve worked exclusively on Long Island no Nassau County, no Connecticut, no out-of-state crews learning the market as they go. Every job we’ve done has been in the same climate, on the same style of homes, under the same permit requirements you’re dealing with right now.
Commack sits across two town lines part of the Town of Huntington, part of the Town of Smithtown and that means your permit has to go to the right building department depending on your exact address. We know which one. We handle all of that as part of every full replacement, so you’re not left figuring out which municipal office to call or whether the job was pulled legally.
Alban, our owner, is mentioned by name in our reviews not because we ask customers to write that, but because he’s the one on the job. That kind of accountability is rare in this industry, and it’s the reason most of our Commack work comes from referrals.
It starts with a free estimate and not a vague ballpark number. We walk the roof, inspect the deck, check the attic ventilation, and look at every penetration point: chimney, skylights, plumbing stacks, anything that creates a flashing detail. From that, you get a fully itemized quote that breaks down tear-off and disposal, deck repairs if needed, underlayment, ice and water shield placement, flashing, ventilation, shingles, and cleanup. Line by line. No lump sums.
Once the job starts, the old roofing comes off completely no overlays, no shortcuts. If we find rotted or soft decking underneath, you’ll know exactly how it’s priced before we continue, not as a surprise on the final invoice. We install architectural shingles rated for 110–130 mph winds as standard on Long Island homes, along with synthetic underlayment and proper ice and water shield at the eaves and valleys the areas most vulnerable to ice dam damage in Commack’s winters. For homes built in the 1960s with original attic assemblies, we also evaluate ridge and soffit ventilation as part of the process, because replacing shingles on a poorly ventilated attic is just delaying the next problem.
When the job is done, we document it. You get photos and video of the completed work the deck condition, the underlayment, the flashing details so there’s a permanent record of what was done and how. Then the site gets cleaned up, including magnet sweeps for nails. You shouldn’t have to wonder what happened under those shingles.

A full roof replacement with Home Team Construction covers the complete scope: full tear-off of existing materials, deck inspection and repair of any damaged sheathing, synthetic underlayment across the entire field, ice and water shield at eaves, valleys, and penetrations, new step and counter flashing at chimneys and walls, ridge and soffit ventilation where needed, architectural shingles installed to manufacturer specs, and a thorough post-job cleanup with nail magnet sweeps. Permits are handled through whichever building department governs your Commack address Town of Huntington or Town of Smithtown and that’s included in the process, not an add-on.
For homes in the Hamlet or another part of Commack where tree canopy is dense and gutters tend to collect debris, we also assess the fascia and soffit condition during the estimate. These areas take a beating over time and are often overlooked until water is already getting in behind them. If your gutters need attention at the same time, we handle that too same crew, same job, no need to coordinate a second contractor.
Financing is available for qualifying projects at 18 months, interest-free. If you’d rather not liquidate savings for a $14,000 roof replacement on a home worth $800,000, that option is there. It’s not a gimmick it’s how a lot of Commack homeowners choose to handle it.
For most single-family homes in Commack the split-levels, hi-ranches, and colonials that make up the bulk of the housing stock here a full replacement typically runs between $10,000 and $20,000. The range depends on the square footage of your roof, the pitch, the material grade you choose, and what the deck looks like once the old shingles come off. Homes with steeper pitches or more complex rooflines with multiple valleys, dormers, or chimney penetrations will land toward the higher end.
The most common reason a job goes over the initial estimate is deck damage rotted or soft sheathing that wasn’t visible until tear-off. We price deck repairs separately and transparently, so if we find something, you’ll know the cost before we continue. Getting a fully itemized estimate upfront not a lump sum is the best way to protect yourself from that kind of surprise. That’s how we quote every job.
The honest answer is that it depends on the age of the roof and how widespread the damage is. If your roof is under 10 years old and you’ve got a few lifted shingles or a flashing failure at the chimney, a targeted repair makes sense. But if the roof is 20-plus years old which describes a large share of Commack homes given the median construction year of 1964 a repair is often just buying time. You’re putting money into a system that’s already at or past the end of its useful life in Long Island’s climate.
The signs that point toward replacement rather than repair include granule loss in the gutters, shingles that are curling or buckling at the edges, daylight visible in the attic, and water stains on ceilings that keep coming back after repairs. If you’ve had the same leak fixed twice and it’s still showing up, the issue usually isn’t the repair it’s the age and condition of the surrounding system. A proper inspection will tell you which situation you’re actually in.
Yes, a full roof replacement requires a building permit in Commack and this is where things get specific to your hamlet. Because Commack spans both the Town of Huntington and the Town of Smithtown, the permit has to be filed with whichever building department has jurisdiction over your specific address. That’s not always obvious, and it’s not something every contractor knows or manages correctly.
Skipping the permit is a real risk. If you sell the home and the buyer’s attorney or inspector discovers unpermitted work, it can delay or kill the sale. It can also create complications with an insurance claim if the adjuster determines the work wasn’t done to code. We handle all permit documentation and filing as part of every full replacement including knowing which of the two building departments to contact based on where your home sits. That’s not an extra step for us; it’s just part of doing the job right.
Ice dams form when heat escaping from the living space warms the upper portion of the roof deck, melting snow that then flows down and refreezes at the cold eave overhang. That ice barrier builds up and forces meltwater back under the shingles, where it gets into the structure causing water stains, damaged insulation, mold, and eventually rotted sheathing if it goes on long enough.
Commack homes built in the 1960s are at higher risk than most people realize. The attic assemblies in that era were built before modern insulation and ventilation codes, and many lack the continuous ridge-and-soffit ventilation that prevents the temperature differential that causes ice dams in the first place. A roof replacement on one of these homes is an opportunity to address that not just swap the shingles. We evaluate attic ventilation as part of every estimate and install the ice and water shield, ridge venting, and soffit ventilation that your home may have been missing since it was built.
Most single-family homes in Commack a standard split-level or colonial on a quarter-acre lot can be fully replaced in one to two days under normal conditions. Larger homes, steeper pitches, or roofs with significant deck damage that needs repair will take longer, but most jobs are done within a week from start to finish including cleanup.
Weather is the main variable on Long Island. We don’t rush jobs to beat an incoming storm, and we don’t start a tear-off if rain is forecast before we can get the new system dried in. Scheduling during spring and fall tends to give the most predictable windows, but we work year-round. If you’re dealing with active damage after a nor’easter or summer storm, we also offer emergency response and when you call, you reach someone who can actually dispatch a crew, not a voicemail.
For the vast majority of Commack homes, architectural asphalt shingles are the right call and not just because they’re the most common. They’re the most practical choice for Long Island’s specific conditions: nor’easters with sustained winds of 40–65 mph, freeze-thaw cycling through the winter, and summer convective storms that can bring higher peak gusts. Architectural shingles rated for 110–130 mph winds are a significant upgrade over the 3-tab shingles that many older Commack homes still have, which are only rated for 60–70 mph.
If you’re in the Hamlet or another part of Commack with a higher-value home and you want a longer-term solution, impact-resistant shingles or a metal roofing system are worth discussing. Metal in particular performs exceptionally well in ice dam conditions and carries a much longer service life than asphalt. The right answer depends on your home’s structure, your budget, and how long you plan to stay and that’s a conversation we have during the estimate, not a decision we make for you.
