You’re running out of space, but you’re not ready to leave Salisbury. The schools work for your kids. Your commute is manageable. Your neighbors are people you actually know.
A dormer gives you the square footage you need without the foundation work, the permit headaches, or the six-figure price tag of a full addition. You get a functional bedroom, a home office with actual windows, or a playroom that doesn’t eat into your first floor.
It’s not just about space. Dormers bring natural light into areas that used to feel like storage closets. They improve your roofline and curb appeal. And if you ever do sell, you’re looking at a return that makes the investment worthwhile—often 40% to 75% depending on the scope and style.
This is how you stay in the home and neighborhood you want without sacrificing the room your family actually needs.
First, we come out and look at your attic space and roofline. Not every home is set up the same way, and we need to see what’s actually possible given your structure, your roof pitch, and your goals for the space.
Once we know what we’re working with, we walk you through design options—gable, shed, hipped—and explain what each style does for your interior space, your exterior look, and your budget. We’re not trying to upsell you on features you don’t need. We’re showing you what makes sense for your home.
Then we handle permits, order materials, and schedule the work. Most dormer projects take four to eight weeks depending on size and complexity. We’ll cut into your roof, frame the dormer, install windows, insulate, and finish the interior so it matches the rest of your home.
You’ll have access to your house the whole time. We clean up daily. And when we’re done, you’ll have livable space where you used to have a dark, unusable attic.

A dormer project isn’t just carpentry. It’s structural work, roofing, windows, insulation, electrical, drywall, and finish work. We handle all of it.
That means we’re coordinating the roof extension, making sure your new structure is weathertight and properly flashed. We’re installing windows that meet Long Island’s energy codes and actually open when you need airflow. We’re running electrical if you’re turning this into a bedroom or office. And we’re finishing the interior so it doesn’t look like an add-on.
In Salisbury and across Nassau County, home prices are high and construction costs reflect that. You’re paying $531 per square foot on average when you buy. A dormer costs a fraction of that and gives you the space you’d otherwise be paying market rate to acquire.
We also know Long Island winters. Your dormer will be insulated correctly. It’ll handle snow load. And if something goes wrong down the line, we’re still here to fix it.
Dormer costs in Nassau County typically range from $20,000 to $50,000 for a full installation, depending on size, style, and interior finishes. A small shed dormer that adds a few feet of headroom might come in closer to $15,000. A larger gable dormer with multiple windows, electrical, and full interior build-out can push past $50,000.
Long Island labor rates run higher than other parts of New York—skilled contractors charge between $150 and $300 per hour here. Materials cost more. Permit fees add up. But you’re still spending far less than you would on a ground-level addition or buying a bigger home in the same neighborhood.
We give you a fixed-price estimate after we see your home. No surprises, no change orders unless you change the scope.
Yes, most dormer projects in Salisbury require a building permit because you’re altering your roofline and adding structural elements. The town wants to make sure the work meets code for safety, snow load, and energy efficiency.
We handle the permit process. That means we pull the permits, submit the drawings, and coordinate inspections. You don’t need to stand in line at the building department or figure out what forms to fill out.
Some smaller dormer repairs or roof extensions might not trigger a permit depending on scope, but full dormer installations almost always do. We’ll tell you upfront what’s required and build that timeline into the project schedule.
Most dormer projects take between four and eight weeks once we start. That includes framing, roofing, window installation, insulation, drywall, and interior finishes.
Weather can slow things down, especially in winter. Permit approval adds time on the front end—usually a few weeks depending on the town’s workload. And if you’re doing custom interior work or adding a bathroom up there, that extends the timeline.
We don’t rush the job to hit some arbitrary deadline. We’d rather do it right the first time than come back and fix problems later. You’ll know the schedule before we start, and we’ll update you if anything changes.
A shed dormer has a single sloped roof that extends from your existing roofline. It’s wide, cost-effective, and adds the most interior space for the money. You’ll see these on a lot of Cape Cod-style homes across Long Island because they maximize headroom without complicated framing.
A gable dormer has a peaked roof and usually includes a single window. It adds less interior space than a shed dormer, but it looks more traditional and works well if you’re trying to match your home’s existing architecture. Gable dormers also cost less because they’re smaller and require less roofing and framing.
Both styles work. It depends on whether you’re prioritizing space, budget, or curb appeal. We’ll show you what makes sense for your home during the estimate.
Yes, dormers typically return 40% to 75% of their cost when you sell, and they make your home more competitive in Salisbury’s market where buyers are looking for space and functionality.
Adding a bedroom increases your home’s appeal to families. Adding natural light and usable square footage makes your house feel bigger without expanding the footprint. And improving your roofline adds curb appeal, which matters in a neighborhood where homes sell for close to $1 million.
Even if you’re not selling anytime soon, a dormer gives you the space you need to stay in your home longer. That’s worth something when the alternative is uprooting your family and paying current market rates for a bigger house.
Yes, we can turn your new dormer space into a full bedroom, bathroom, or home office. That means running plumbing if you’re adding a bathroom, installing electrical outlets and lighting, and finishing the space with drywall, flooring, and trim that matches your home.
Adding a bathroom in a dormer is more complex because you need to tie into your existing plumbing and make sure the floor structure can handle the load. It’s doable, but it adds cost and time to the project.
Bedrooms are more straightforward—you need egress windows for code compliance, electrical, and climate control. We handle all of that. When we’re done, the space functions like any other room in your house.
