Custom Roof Vents

Roof vents serve two main purposes: air intake and exhaust. They come in many different shapes and sizes. Intakes are usually placed in the soffit area, but sometimes are placed on the roof near the eave. The exhaust vent is found near the ridge of the roof and is sometimes integrated into the roof system on top of the ridge.

What Are Custom Roof Vents?

A custom roof vent is an extremely important part of any roofing system, designed to improve attic ventilation, regulate air flow and prevent moisture buildup. By allowing hot air to escape and fresh air to enter, roof vents help maintain a balanced temperature in your attic space, reducing the strain on your heating, ventilation and air conditioning (HVAC) system.

At Salvo Metal Works, we craft custom roof vents of various sizes and styles in our workshop in Naperville, IL, using a variety of materials. Customization ensures a perfect fit for any roof pitch or design. Whether you’re looking for metal gable vents, round exhaust vents or surface-mount ventilation solutions, we have the expertise to manufacture durable and efficient vents tailored to your specific project needs.

Our vents not only improve air flow but also enhance curb appeal, blending seamlessly with your home’s roofing and exterior design. Built from high-quality metals, our vents are designed to withstand extreme weather conditions, including wind-driven rain and UV exposure.

Benefits of Custom Roof Vents

Improved Attic Ventilation & Air Flow – A well-ventilated attic prevents heat buildup in warmer months and helps regulate indoor temperature year-round. Proper air circulation reduces strain on your HVAC system, leading to more efficient energy use and lower utility bills.
Prevention of Moisture, Mold & Mildew – Without proper ventilation, humidity and condensation can build up in your attic, leading to mold growth, mildew and structural damage. Vents allow moisture to escape, protecting your house, insulation and roofing materials from deterioration.
Enhanced Curb Appeal & Customization – Unlike standard off-the-shelf vents, custom metal roof vents are designed to complement any architectural style, from modern homes to historic renovations. Choose the material and design that matches your roof, siding and exterior details.
Durability & Weather Resistance – Crafted from high-quality metals, custom roof vents are built to withstand extreme weather, including wind-driven rain, snow and UV exposure. Whether installed on a flat roof, metal roof or steep-pitched structure, these vents are made to provide long-lasting performance.
Custom Sizes & Styles for Any Job – Custom roof vents are available in multiple configurations, including:
- Gable vents – Perfect for attic ventilation.
- Round vents – Ideal for exhausting hot air and improving air flow efficiency.
- Louvered vents – Designed for enhanced intake and exhaust ventilation, louvers prevent blockages from debris or pests.
- Custom decorative vents – Tailored to complement high-end homes, barns and commercial buildings.

Roof Vent Materials: Choosing the Right Option

At Salvo Metal Works, we manufacture custom roof vents using premium materials to ensure maximum durability and efficiency. Here are some of the most popular options:

Copper – A luxurious and long-lasting choice, copper develops a natural patina over time, blending beautifully with traditional and modern architecture.
Aluminum – Lightweight, rust-resistant and available in painted finishes, aluminum vents provide a sleek, durable solution for ventilation needs.
Galvanized Steel – Built for strength and weather resistance, galvanized roof vents are ideal for industrial, agricultural and residential applications.
Powder-Coated Metal Finishes – Available in a range of colors and textures, powder-coated vents offer customization options while adding extra protection against moisture and UV exposure.

Custom Roof Vents

What are custom roof vents and when are they needed?

Custom roof vents are specially fabricated ventilation systems designed to meet unique architectural requirements or performance specifications. They're needed when standard vents don't fit roof dimensions, match aesthetic requirements, or provide adequate airflow for specific applications like complex roof designs, historic restorations, or buildings with unusual ventilation requirements.

How do I determine the right size and number of custom roof vents?

Proper sizing follows the 1:150 or 1:300 rule—one square foot of vent area per 150‑300 square feet of attic space, depending on vapor barriers. Custom vents allow precise calculations for complex roof geometries. Split ventilation evenly between intake and exhaust, with intake vents at eaves and exhaust near the ridge for optimal airflow.

What materials are used for custom roof vents?

Custom roof vents are fabricated from copper, stainless steel, galvanized steel, aluminum, or specialized alloys. Copper provides longevity and attractive patina; stainless steel offers corrosion resistance; aluminum is lightweight and cost‑effective. Material selection depends on climate exposure, architectural style, and budget considerations.

Can custom roof vents improve energy efficiency and prevent damage?

Yes—properly designed custom vents regulate attic temperatures, reducing HVAC strain and energy costs. They prevent moisture buildup that causes mold, rot, and premature shingle deterioration. In winter, they help prevent ice dams by maintaining consistent roof temperatures and reducing condensation issues.

What types of custom roof vents are available?

Options include custom ridge vents, box vents, gooseneck vents, turbine vents, and powered exhaust systems. Each can be tailored for specific roof styles—hip roofs, complex geometries, or buildings requiring specialized airflow patterns. Design features like screens, baffles, and weather protection can be integrated based on local climate needs.
