You’re running out of space. The kids need separate rooms, you need a home office, or you just want somewhere that doesn’t feel like a storage closet. Moving isn’t realistic right now—not with home prices in Nassau County hitting $800,000 and mortgage rates sitting in the mid-6% range when you’re locked into 3%.
A dormer gives you the square footage you need without the chaos of moving. You get an actual bedroom with headroom and windows. Natural light floods in where it used to be dark and stuffy. Your home’s value goes up—dormers return 40-50% of what you invest, so a $20,000 project could add $8,000 to $10,000 in equity.
You stay in the neighborhood you love. Your kids stay in their schools. And you finally have the space your family actually needs.
We handle large-scale residential projects across Long Island, and dormers are one of our specialties. We’re not the guys who ghost you after the estimate or leave your house looking like a construction zone for weeks.
When you call, we answer. When you text, we respond. If something urgent comes up—frozen pipes, weather damage, anything—we’re there. Our crews keep job sites clean, show up when they say they will, and treat your home like it matters.
We’ve built our reputation in Island Park and surrounding Nassau County towns by doing what most contractors won’t: staying in touch, staying professional, and getting the job done right. If you’re looking for a dormer contractor who actually communicates, you’re in the right place.
First, we come out to look at your attic and roof structure. We measure everything, talk through what you’re trying to accomplish, and figure out what type of dormer makes sense—shed, gable, hipped, whatever fits your home’s architecture and your goals.
Then we give you a clear estimate. No surprises, no vague line items. We walk you through the timeline, the materials, and whether permits are needed. A lot of our dormer projects don’t require permits, which speeds things up, but if yours does, we handle it.
Once you’re ready to move forward, we schedule the work and get started. We open up the roof carefully, frame out the dormer structure, install windows, insulate properly for Long Island winters, and finish the interior so it matches the rest of your home. Throughout the job, we keep the site clean and keep you updated.
When we’re done, you’ve got a finished room with real ceiling height, plenty of light, and space you can actually use. No mess left behind, no half-finished details.

A dormer isn’t just a roof bump—it’s a full transformation of unusable attic space into livable square footage. You get proper headroom, real windows for natural light and ventilation, and a room that feels like part of your house, not an afterthought.
In Island Park and across Long Island, homeowners are choosing dormers because they’re cost-effective compared to full additions. Where a ground-level addition might run $100,000 or more, a quality dormer typically costs between $15,000 and $40,000 depending on size and complexity. You’re adding a bedroom, office, playroom, or whatever you need without the massive expense of building out.
We handle everything: structural framing, roofing, windows, insulation rated for cold Long Island winters, drywall, and finishing. If you want the interior painted or flooring installed, we do that too. The goal is a turnkey space that’s ready to use the day we finish.
And because we specialize in projects that often don’t require permits, we can move faster than competitors who get bogged down in bureaucracy. You get your space sooner, with less hassle.
Dormer costs in Long Island typically range from $8,000 for a small dormer to $40,000 for a larger, more complex project. Most homeowners spend around $20,000 for a standard dormer that adds meaningful square footage.
The final price depends on size, dormer style, how much structural work is needed, and what finishes you want inside. A shed dormer that runs along most of your roofline will cost more than a small gable dormer over one window. If we need to reinforce floor joists or add significant insulation, that affects the price too.
We give you a detailed estimate upfront so you know exactly what you’re paying for. No hidden fees, no vague “we’ll figure it out later” pricing. And because dormers add 40-50% ROI, you’re not just spending money—you’re investing in your home’s value.
It depends on the scope of the project. Many dormer installations do require permits, especially if you’re adding significant square footage or changing the roofline substantially. But some smaller dormers or specific types of roof work don’t trigger permit requirements.
This is one of our specialties—we know which projects need permits and which don’t. If your dormer does require a permit, we handle the paperwork and make sure everything is filed correctly with the town. Open permits can show up on title searches and block home sales down the road, so we make sure it’s done right from the start.
If your project doesn’t need a permit, we can move faster and save you the hassle and fees. Either way, we’re upfront about what’s required before we start any work.
A shed dormer has a single sloping roof that extends out from your existing roofline. It’s the most common type because it maximizes interior space—you get the most headroom and square footage. Shed dormers often run along a large section of the roof, sometimes the entire length.
A gable dormer has a peaked roof, like a little house sitting on top of your main roof. It’s smaller than a shed dormer and adds less interior space, but it can look more traditional and match certain architectural styles better. Gable dormers are great for adding light and some extra room without changing the entire roofline.
We’ll walk you through which style makes sense for your home based on what you’re trying to accomplish, your budget, and what looks right with your existing architecture. Both types work well in Island Park homes—it just depends on your specific situation.
Most dormer projects take two to four weeks from start to finish, depending on size and complexity. A small gable dormer might be done in two weeks. A large shed dormer that runs the length of your roof could take a month.
Weather can affect the timeline, especially during Long Island winters when we need to work around snow, ice, and freezing temperatures. We plan for that and make sure your home stays protected throughout the process—no leaks, no exposure to the elements.
We give you a realistic timeline upfront and keep you updated if anything changes. You won’t be left wondering when we’re coming back or how much longer the job will take. We show up when we say we will, work efficiently, and finish the job right.
Most homes can accommodate a dormer, but it depends on your roof structure, pitch, and attic space. We need enough roof slope to build the dormer without it looking awkward or creating structural issues. We also need adequate attic floor joists to support the additional weight and living space.
During the initial consultation, we assess your roof framing, measure the attic, and figure out what’s feasible. If your attic floor needs reinforcement, we handle that as part of the project. If your roof pitch is too shallow, we’ll tell you upfront—we’re not going to sell you something that won’t work.
Most Island Park homes were built with enough roof pitch to support dormers, especially the Cape Cod and Colonial styles common in Nassau County. But every house is different, and we make sure the dormer fits your home structurally and aesthetically before we start.
Absolutely. Proper insulation is critical for any dormer, especially with Long Island’s cold winters. We insulate the walls, ceiling, and floor of the dormer to the same standards as the rest of your home—often better, since we’re building new.
Poor insulation leads to frozen pipes, ice dams on the roof, and sky-high heating bills. We’ve seen it happen with other contractors who rush the job or skip steps. We don’t. We use quality insulation materials, seal everything properly, and make sure your new space stays warm in winter and cool in summer.
If something does go wrong—a pipe freezes, a leak develops—we offer emergency response. We’re not the kind of contractor who disappears after the check clears. You call, we answer, and we fix it. That’s how we do business.
