The Ultimate Guide to Long Island Dormers, Extensions, Porticos, & Residential Framing

Over 35 Years as a Roofer in Long Island

Transform Your Long Island Home
with Dormers, Extensions, and Porticos

Expanding your Long Island home with residential framing projects like dormers, extensions, or a new portico can add value, space, and curb appeal. Extensions offer the perfect solution for growing families needing more room without moving. By adding square footage, you can create a larger kitchen, extra bedrooms, or even a home office. With thoughtful planning, an extension integrates seamlessly with your home’s original design, maximizing both style and functionality.

Dormers, on the other hand, are an excellent way to transform an attic into a cozy loft apartment or extra bedroom. By bringing in natural light and headroom, dormers make formerly cramped attic spaces livable and inviting. And for those who want to enhance their home’s entrance, a portico offers instant curb appeal, giving a stylish and welcoming feel that also shields guests from the elements.

At County Roofing Systems, we bring over 35 years of expertise in residential framing and renovations. We understand the unique needs of Long Island homeowners and can guide you from planning through completion. Let’s explore how these additions can elevate your home and provide the space and style you’ve been dreaming of!

A Quick Explanation of Residential Framing

Residential framing forms the backbone of any home addition. It provides the structural support needed to ensure your new addition is safe, durable, and perfectly aligned with your existing home. Proper framing lets you expand your home’s footprint or add features like dormers and porticos.

When adding a dormer, framing creates the necessary headroom and stability to transform an attic into a comfortable, usable space. The framing process involves reinforcing your roof’s structure to support the dormer’s added weight and allow for proper insulation and weatherproofing.   For extensions, residential framing supports walls, floors, and ceilings, ensuring your new space blends well with your home’s current structure.

Porticos, though smaller, also rely on sturdy residential framing to connect securely to your home’s entryway. This framing step is vital, as it must support both the portico’s roof and any added features, like columns or decorative elements. 

Different Types of Residential Framing

Residential framing may not be visible, but it’s crucial for any home improvement project. Whether adding a dormer, extension, or portico, a solid frame ensures safety and durability. The most common type of residential framing for new builds is platform framing. It uses each floor as a base for the next. For tall continuous spaces, contractors use balloon framing. This method involves long studs that run from the ground to the roof. And for open floor plans without many interior walls, post and beam framing is used.

Strong framing guarantees the longevity and safety of your home additions. It protects your home from the elements and  allows for optimal insulation placement so your space stays comfortable year round. 

Dormer Installation:
Adding Height and Light
to Your Long Island Home

 

Adding dormers to your Long Island home offers both practical and aesthetic benefits. Dormers bring in natural light, brightening up previously dark attic spaces and making them more inviting. With extra headroom, you can transform your attic into a cozy loft, guest bedroom, or even a home office—perfect for growing families needing additional space without moving.  Windows in dormers also allow for better airflow, which can reduce humidity in your upper floors.

Dormers also enhance your home’s curb appeal, adding character and architectural interest to your roofline. Whether you choose a classic gable dormer or a unique eyebrow style, this upgrade can boost your property’s value and appearance.

Some Dormer Types We Install

Gable Dormer

Gable dormers feature a gabled roof with two sloping planes that meet at a central ridge, forming a triangle.

Hip Dormer

Hip dormers have a roof that slopes on all three sides, converging at the top.

Shed Dormer

Shed dormers have a single roof plane that slopes downward at an angle less steep than the main roof.

Eyebrow Dormer

This style is characterized by a low and wide curved roof, resembling an eyebrow.

Arched Dormer

Featuring an arched roof above the window, this type adds a classic and elegant touch to the home’s exterior.

Wall Dormer

A wall dormer extends upward from the wall, raising the roofline section where it's placed.

Nantucket Dormer

Combining two gable or shed dormers with a connecting roof in between, Nantucket dormers maximize the space and create a more substantial architectural feature.

Mansard Dormer

Set into a mansard roof, these dormers are often small and placed to punctuate the steep lower slope of the roof.

From Design to Finishing Touches: How We Install Dormers

1. Initial Consultation

We meet with you to  discuss design preferences, dormer type, and budget for a clear project vision. Our team has decades of experience working on all types of Long Island and traditional houses and can help you find the perfect dormers for your home.

2. Site Assessment and Measurements

Our dormers and framing specialist examines your attic space, roof structure, and measurements to ensure the dormer will fit seamlessly with your home. We give you a report of our findings and discuss any repairs required or issues that must be dealt with.

3. Design Approval and Permits

Once we finalize the dormer design, we take care of acquiring the required permits and ensure compliance with local building codes. This is a very important step in Long Island, where local laws and HOA rules must be followed stringently on every project.

4. Framing and Structural Reinforcement

Our team frames the dormer and reinforces the roof to support the new structure securely. Residential framing is the foundation for everything that comes afterwards. 

5. Roof and Wall Installation

Once framing is complete, the walls and roof are constructed, with care taken to match your home’s existing style. We make sure your new dormer is both soundly constructed and aesthetically pleasing. 

6. Window Installation

The contractor installs windows to allow natural light and proper ventilation, enhancing the dormer’s function and comfort. You can select from a wide variety of windows to meet your needs and your budget.

7. Insulation and Waterproofing

Insulation and weatherproofing keep the space comfortable and protected from the elements.  A poorly sealed dormer will lead to roof leaks and drafts, so we take pains to make sure that every step is completed properly. 

8. Interior and Exterior Finishing

Drywall, painting, and any other interior finishes transform the dormer into a usable living area. Finally, the contractor matches siding and roofing materials for a seamless exterior look.

Planning Your Home Extension:
Key Considerations for
Long Island Homeowners

Adding a home extension is a fantastic way to increase space and functionality without the hassle of moving. Long Island homeowners can create customized areas, from expanded kitchens to extra bedrooms or even a new home office. Extensions allow you to keep your existing property while making room for a growing family or changing needs.

Beyond adding valuable square footage, a well-designed extension also boosts curb appeal and property value. Whether you’re envisioning a single-story addition or a multi-level expansion, planning your extension with the right design and materials will make your Long Island house feel like a brand new home.

Types of Home Extensions

Single-Story Extensions are ideal for expanding your kitchen, living room, or dining area without impacting the second floor.  You can also add an additional room for use as a home offie, workout area, or entertainment room.

Multi-Story Extensions are a good choice for Long Island homeowners who have a smaller plot. We can add bedrooms, bathrooms, or even a home office with a second-story addition. You save lawn space and use your home’s space efficiently. 

Garage Conversions are popular with Long Islanders who want to transform their garage into a livable area, creating a bonus room or even a small apartment.

Step-by-Step Guide to Building a Home Extension on Long Island

1. Initial Consultation and Planning

We discuss your goals, design ideas, and budget. Together, we plan the extension’s layout, materials, and overall vision. This stage includes site assessments and discussing any specific needs or preferences. A clear initial plan sets the foundation for a smooth, efficient project that meets your family’s requirements.

2. Design and Blueprints

We work with an architect to create detailed design plans and blueprints. These drawings outline dimensions, structural details, and interior layouts. Well-prepared blueprints ensure accuracy, prevent issues, and align with your vision. With finalized blueprints, you’re ready to move into the permitting phase.

3. Design and Blueprints

Permits are essential for building an extension on Long Island. Your contractor helps secure permits, ensuring your extension meets local building codes. Permitting protects you from fines and ensures your project follows zoning and safety regulations. This step may take a few weeks, depending on local authorities.

4. Site Preparation and Foundation

Our team clears and prepares the building site, marking the extension’s outline. Next, they lay the foundation, which may include excavation, pouring concrete, and ensuring that it’s level. The foundation is crucial for stability, providing a solid base for your new space

5. Framing the Structure

Once the foundation is set, framing begins. This stage includes building walls, floors, and the roof structure. Framing shapes the extension’s layout, creating the skeleton that supports walls, windows, and doors. Quality framing ensures the addition integrates with your home and remains structurally sound in all weather.

6. Installing Roof and Exterior Walls

After framing, the contractor adds roofing and exterior walls, sealing the structure from the elements. This step includes installing roofing materials, siding, and weatherproofing. The exterior protects the extension from rain, wind, and snow, ensuring it’s ready for interior work.

7. Electrical and Plumbing Work

Licensed electricians and plumbers handle wiring, outlets, and any plumbing fixtures needed for your extension. This stage also includes HVAC setup if required. Properly installed systems ensure your new space is comfortable, functional, and safe. After inspections, the team can start closing walls with insulation and drywall.

8. Insulation and Drywall Installation

Insulating walls and ceilings improves energy efficiency, keeping the extension warm in winter and cool in summer. After insulation, the contractor installs drywall, smoothing and preparing it for painting. Insulation and drywall transform the extension’s interior into a comfortable, finished space ready for final touches.

9. Flooring, Painting, and Finishes

With walls prepped, floors, paint, and finishes are added. This step includes installing hardwood, tile, or carpet, painting walls, and adding trim or molding. These finishing touches create a polished, welcoming space. We work with you to match colors, textures, and designs with your style preferences.

10. Final Inspections

Once completed, the contractor arranges final inspections to ensure everything meets code. After passing, they conduct a walkthrough with you to review the work and address any final adjustments. Final inspections ensure safety, quality, and satisfaction. You’ll now have a beautiful, functional extension ready for your family to enjoy.

Why Add a Portico?
Top Benefits for Long Island Homes

Installing a portico on your Long Island home’s entryway brings both style and functionality. A portico creates a welcoming, attractive entrance that immediately boosts curb appeal. With various designs to choose from, you can customize a portico to match your home’s architectural style, adding a touch of elegance and enhancing visual interest.

Beyond appearance, a portico protects your entryway from rain, snow, and sun, helping keep your door and entry area in top shape. This added shelter reduces weather-related wear, which means less maintenance over time. With improved aesthetics and practical benefits, a portico adds real value to your Long Island property, making it more appealing to guests and potential buyers alike.

Types of Porticos

Azek Portico

There are several types of porticos that add unique style and functionality to your home’s entrance. Flat-roof porticos offer a simple, modern look, providing basic protection from the elements. Often supported by columns or decorative posts, flat-roof porticos work well with contemporary or minimalist architectural styles and are a popular choice for homeowners looking for a straightforward, sleek entry feature.

Gabled porticos, with their pitched rooflines, add height and character to an entrance. This style suits traditional and colonial-style homes, creating a grander, more inviting look. The angled roofline allows rain and snow to easily slide off, which is especially beneficial in regions with variable weather. Gabled porticos can range in design from simple to more elaborate, with options to add accent lighting, trim details, or custom columns.

For a touch of sophistication, arched porticos bring a rounded elegance that softens and elevates the home’s facade. This style complements a variety of architectural designs, adding a unique focal point to the entryway. Arched porticos require precise framing for the curved structure but offer an upscale look that’s highly appealing for those aiming to boost curb appeal. With these styles, you can find the perfect portico to match your home’s character and enhance its welcoming feel.

Your Portico Installation: A Step-by-Step Guide

1. Initial Consultation and Planning

We meet with you to discuss your vision, style preferences, and portico budget. You will determine the portico type—flat, gabled, or arched—and select materials. Your contractor will assess your home’s entrance for any specific requirements. Detailed planning ensures a portico design that suits both your home and needs.

2. Securing Permits and Approvals

County Roofing will handle the permit process, ensuring compliance with local building codes and homeowner association guidelines. Securing permits protects your investment and helps avoid any legal complications. Allow time for the approval process to avoid project delays.

3. Site Preparation and Demolition

Our crew prepares the work area, removing any existing structures or obstacles. They mark the layout and ensure the site is ready for a new foundation. Proper site preparation prevents issues and sets a clean base for construction. This stage includes protecting nearby landscaping and pathways from debris or damage.

4. Foundation and Footing Installation

The foundation provides stability for the portico’s structure. Contractors dig and pour concrete footings or posts, ensuring they’re level and securely anchored. A solid foundation is essential for supporting the portico’s weight and withstanding Long Island’s weather conditions. We also verify that the foundation is precisely aligned.

5. Framing and Structural Support

With the foundation ready, framing begins. This includes erecting posts, beams, and the portico’s roof frame.  We use durable materials and precise measurements to ensure structural stability. Quality framing provides long-lasting support for the portico, aligning it seamlessly with your home’s entrance.

6. Roofing and Siding Installation

Our team adds roofing material that matches or complements your home’s roof. This may include shingles, metal, or other weather-resistant materials. Siding, trim, or columns are also installed as part of the portico’s exterior. Proper roofing and siding ensure weather protection and a cohesive look with your existing structure.

7. Painting and Finishing Touches

Once the structure is complete, we add finishing touches like painting and decorative elements. Painting protects the materials from the elements while adding visual appeal. Trim, moldings, or decorative details give the portico a polished, customized look. Finishing touches add style and blend the portico with your home’s aesthetic.

8. Final Inspection and Quality Check

After completing construction, we perform a final inspection to confirm quality and compliance with building codes. We check structural integrity, finish details, and functionality. Any necessary adjustments are made to ensure the portico meets expectations. This thorough inspection guarantees a safe and attractive addition.

9. Project Cleanup and Walkthrough

Our team cleans the site, removing debris and protecting landscaping. Then we walk you through the finished portico, answering questions and providing maintenance tips. A clean, complete walkthrough ensures you’re satisfied with the results and understand how to care for your new portico.
