You’re not imagining it. Your home feels smaller than it used to. Kids need their own rooms. You need a real office, not a corner of the dining room. Moving sounds exhausting, and building out isn’t an option thanks to lot size restrictions across Woodbury.
A dormer changes that. It opens up your attic, brings in natural light, and adds functional square footage—without touching your property line or dealing with the nightmare of relocating.
You stay in the neighborhood you love. Your kids stay in their schools. And you finally get the space you’ve been trying to carve out for years. That’s what a well-built dormer does. It solves the problem without creating ten new ones.
We’ve been handling large-scale residential projects across Nassau County for more than four decades. Dormers, kitchen remodels, first-floor renovations—we do the work that requires precision, experience, and someone who actually answers the phone.
We’re not a crew that shows up once a week. The owner is on-site daily. The job gets cleaned up every afternoon. And if your pipe freezes at 3 a.m. in January, we pick up.
Woodbury homeowners deal with tight zoning, expensive real estate, and contractors who ghost after the deposit clears. We’ve built a reputation here by doing the opposite—showing up, staying available, and finishing what we start.
First, we come out and look at your attic. Not every roof can support a dormer, and not every layout makes sense for one. We’ll tell you what’s possible, what’s not, and what it’ll cost before you commit to anything.
Once we’re moving forward, we handle the framing, roofing, insulation, windows, and interior finish work. The structure gets built, the roof gets tied in, and the inside gets turned into actual living space. We’re talking drywall, flooring, electrical—the whole build.
Most dormer projects take six to ten weeks depending on size and weather. We keep the site clean daily, and you’ll have direct contact the entire time. No project manager middleman. No wondering when someone’s coming back.
You’ll know what’s happening because we’ll be there to tell you.
Ready to get started?
A dormer isn’t just a bump-out on your roof. It’s a full structural addition that includes framing, roofing, siding to match your home, insulation that meets code, windows that actually open, and finished interior space ready for furniture.
In Woodbury, most homeowners go with shed dormers because they maximize headroom and usable square footage. Gable dormers work too, especially if you’re after curb appeal or trying to match existing architecture. We’ll walk you through both.
The cost typically runs between $8,000 and $50,000 depending on size, materials, and how much interior work you want done. That’s a fraction of what you’d spend moving to a bigger house in the same neighborhood—and your property value goes up in the process.
We also handle dormer repairs if you’ve got an older one that’s leaking or sagging. Roof extensions, structural reinforcement, window replacement—we’ve seen it all and fixed most of it.
Dormer costs in Woodbury generally range from $8,000 to $50,000. That’s a wide range because size matters. A small dormer that adds a closet or bathroom is cheaper than a full shed dormer that turns your entire attic into a master suite.
Nassau County pricing also runs higher than other parts of Long Island due to labor costs and material quality. You’re paying for skilled framers, licensed electricians, and contractors who know how to tie a dormer into your existing roof without creating a leak point.
We give you a fixed price after the initial visit. No surprises, no change orders unless you change the scope. You’ll know what it costs before we touch a board.
Most dormers require a building permit in Woodbury, especially if you’re adding square footage or altering the roofline. The Town of Oyster Bay handles permitting for this area, and yes, the process can take time.
That said, some smaller roof modifications or repairs don’t trigger permit requirements. We’ll tell you upfront whether your project needs one or not. If it does, we can handle the filing and inspections so you’re not stuck navigating town hall.
Permit backlogs are real on Long Island, and they can add weeks to a timeline. That’s why we focus on keeping everything code-compliant from the start—so inspections go smooth and you’re not dealing with correction notices halfway through the job.
Plan on six to ten weeks for most dormer projects. Smaller builds can finish faster. Larger ones—especially if we’re finishing the interior as a full bedroom or office—take longer.
Weather plays a role too. We’re not framing a roof in a rainstorm, and winter jobs can hit delays if we get hit with snow or frozen ground. We’ll give you a realistic timeline based on the season and scope.
You won’t be left guessing. We update you throughout, and the owner is on-site daily to keep things moving. Most contractors disappear for days at a time. We don’t operate that way.
Yes. Adding livable square footage almost always increases property value, and dormers can boost your home’s worth by up to 22% depending on the size and quality of the build.
In Woodbury, where home prices are among the highest in New York, that percentage translates to serious equity. You’re also making your home more competitive if you ever decide to sell. Buyers want space, light, and flexibility—dormers deliver all three.
Even if you’re not selling anytime soon, you’re still getting the benefit now. More room for your family. A home office that’s actually separate from the kitchen. A guest room that doesn’t double as storage. That’s value you use every day.
Not every house is a good candidate. Your roof pitch needs to be steep enough to create usable headroom, and your attic framing has to support the additional load. Some older homes also have roof structures that make dormer installation complicated or cost-prohibitive.
We assess all of that during the first visit. If your roof won’t work for a dormer, we’ll tell you. If it will, we’ll show you where it makes the most sense and what kind of dormer fits your layout.
Most homes in Woodbury were built with enough pitch and structure to handle a dormer, especially the colonials and capes common in the area. But we don’t guess—we measure, calculate, and give you an honest answer.
A shed dormer runs along the length of your roof and creates a long, wide space inside. It maximizes square footage and headroom, which is why most people choose it when they want a full bedroom, office, or bathroom upstairs.
A gable dormer is smaller and projects out from the roof like a little house. It adds light and some extra space, but it’s not as dramatic. Gable dormers are better for aesthetics or when you just need a window and a bit more headroom in one spot.
Both work. Both add value. It comes down to how much space you need and what your roof can handle. We’ll show you examples of both and help you decide which makes sense for your home and budget.
