With the help of a professional dormer contractor, you can take that unused attic space and turn it into a beautiful, functional room.

But only the best dormer contractors and designers can do it. And you need to be very vigilant while looking for one. 

However, in this blog we will explore how dormers can help, why you need the right contractor, how Long Island homeowners are using dormers to improve their homes, and why Selective Remodeling stands out as the trusted name for dormer additions

What is a Dormer?

A dormer is a structural extension that projects from the slope of a roof and usually includes a vertical window. This small addition can make a big difference in your home. By increasing the amount of usable interior space, adding more headroom, and allowing natural light to pour in, dormers completely change the feel and functionality of your upper floor or attic area.

Instead of leaving your attic dark, cramped, and unusable, a dormer allows you to turn that space into something valuable. Many homeowners choose to install dormers when they want to add extra bedrooms, upstairs bathrooms, quiet home offices, reading nooks, or even spacious walk-in closets. The beauty of a dormer addition is that it lets you expand your living space without having to increase your home’s overall footprint or break into your backyard. 

This makes dormers especially appealing for homes on Long Island, where zoning restrictions and lot sizes often limit outward expansion. When space is tight, building up with a dormer is a smart alternative. A qualified dormer contractor on Long Island, NY can help you explore the different types of dormers that best suit your home’s layout and your family’s lifestyle needs.

Hiring the best dormer contractors means you’ll get expert advice on how to integrate a dormer seamlessly with your roof structure and exterior design. The right contractor will also ensure your dormer meets local building codes and delivers long-term durability.

Why Long Island Homeowners Choose Dormers

If you are living in Long Island and want an open area at home. Then you should consider dorming or leaving this place. Why? Because here zoning rules and limited lot sizes don’t allow you to expand. 

That’s why most homeowners choose dormers at home and go up instead of outside.

However, the following are the benefits of adding a dormer:

  • Extra usable square footage
  • More natural sunlight in upper floors
  • Enhanced curb appeal and architectural character
  • Increased home value
  • Better ventilation and airflow

Dormers especially suit Cape Cod, ranch, and colonial-style homes that dominate Long Island neighbourhoods.

Common Types of Dormers

Best Dormer Contractors

Struggling with finding the right type of dormer for your home? A professional dormer contractor on Long Island, NY, can help you choose the best option based on your home’s structure and style.

However, the following are the main types of dormers that are famous in Long Island, NY: 

1. Gable Dormer

Gable dormers are among the most popular styles in Long Island. They feature a pitched roof with two sloping sides that form a triangle over the window. 

In addition to improving curb appeal, gable dormers create more headroom and usable space in upper levels. A skilled dormer contractor will make sure the dormer blends smoothly with your existing roofline.

2. Shed Dormer

Shed dormers have a single sloping roof and usually run along the length of the home. They provide the most interior space, making them ideal for large rooms like bedrooms or home offices.

This style is perfect if you want to turn your attic into a full, functional living area. A dormer contractor on Long Island, NY, can build shed dormers that are energy-efficient and designed to withstand local weather.

3. Hip Dormer

Hip dormers have three sloped sides and are often used on homes with existing hip-style roofs. While they provide slightly less interior space, they offer excellent stability and a balanced appearance.

This type of dormer is a good option for homes in windy or coastal areas. A top dormer contractor ensures proper construction to avoid leaks and structural issues.

4. Eyebrow Dormer

Eyebrow dormers have a curved roofline and are chosen for their visual appeal. They work well with cottage or shingle-style homes and add a unique, elegant touch to the roofline.

While they don’t create much extra space, they do add charm and character. Proper installation by a professional dormer contractor is essential to avoid issues with framing and waterproofing.

Each dormer type has its own benefits. A professional dormer contractor on Long Island, NY, like Selective Remodelling, will guide you in choosing the best option for your home.

Cost of a Dormer Addition on Long Island

  • Medium dormer (adds standing space): $8,000–$20,000
