Metal Building Roof Types

Your Most Important Decision

Understand the Difference Between Regular, A-Frame, and Vertical to Protect Your Investment.

When designing your metal buildings, you can customize the size, doors, and colors, but no choice is as crucial as the metal building roof type. The roof style not only defines your structure's appearance but also determines its ability to withstand the elements, its long-term durability, and its overall performance. It's the first and most important line of defense for everything you store inside.

At Steel Building Stores, we want you to make an informed decision. This guide breaks down the different types of steel roof so you can clearly understand the advantages of each steel roof type. We'll help you choose the perfect option that fits your climate, your budget, and the needs of your steel buildings, ensuring decades of worry-free protection.

The Right Roof for Your Climate: A U.S. Geographic Guide

Not all roofs are created equal because not all climates are equal. A building in sunny Southern California faces very different challenges than one in snowy Maine. At Steel Building Stores, we help you choose a steel roof type not just for its looks, but for its performance right where you live.

  • Heavy Snowfall Zones (The Snow Belt - Northeast, Midwest, Rockies)

    In these regions, heavy snow accumulation is a roof's greatest enemy. For these areas, the Vertical Roof is not just a recommendation—it's a necessity. Its vertical panels allow snow to slide to the ground with gravity, preventing dangerous weight build-up that can compromise the structure. Horizontal-paneled roofs can trap snow, creating ice dams and increasing risk.

  • Heavy Rain & Debris Zones (Southeast, Pacific Northwest)

    In areas with torrential rainfall, hurricanes, or a lot of leaves and pine needles, efficient drainage is key to the longevity of your metal buildings. A Vertical Roof's channel design ensures water and debris flow unobstructed from the peak to the eaves, preventing pooling, leaks, and long-term corrosion.

  • Moderate & Dry Climate Zones (Southwest, parts of the South)

    In regions where the main concern is intense sun and rainfall is light or infrequent, you have more flexibility. Here, types of steel roof like the Regular Roof (the most economical option) and the A-Frame Roof (with an upgraded aesthetic) are excellent, cost-effective solutions. They provide all the necessary protection from the sun and light rain at a more accessible price point.

Good, Better, & Best: The Steel Building Stores Guide

Each metal building roof type we offer is designed for a different level of performance and budget. At Steel Building Stores, our priority is for you to understand the key differences so you can make a smart, long-lasting investment in your metal buildings.

Regular Roof (Economical & Functional)

Regular Roof (Economical & Functional)

This is the original and most economical roof style in the industry. It's easily recognized by its rounded, barn-like corners and its horizontal roof panels that run the length of the building. At Steel Building Stores, we recommend this option for smaller carports and buildings in areas with very mild weather, where heavy rain or snow is not a concern. It's an excellent, cost-effective solution for providing shade and protection from light rain.

Its main advantage is the cost, offering a protective cover at the lowest possible price point. It's a testament to the simplicity and efficiency that made steel buildings popular in the first place.

A-Frame / Boxed-Eave Roof (Traditional Aesthetics, Better Strength)

A-Frame / Boxed-Eave Roof (Traditional Aesthetics, Better Strength)

The A-Frame roof, also known as a "Boxed-Eave," was designed for customers who want a more conventional appearance, similar to a traditional house roof. It features a peaked 'A' shape with straight eaves and a cleaner, finished trim, allowing it to blend in better aesthetically with existing homes. Although its panels also run horizontally, its A-frame design gives it greater structural strength than the regular roof.

This style is the most popular choice at Steel Building Stores for garages and workshops, as it offers a perfect balance between an upgraded look and a moderate cost. It's a steel roof type that performs exceptionally well in areas with moderate rainfall and wind.

Vertical Roof (Superior Performance & Durability - The Best Option)

Vertical Roof (Superior Performance & Durability - The Best Option)

This is, without question, the best and strongest of all types of steel roof available. While it shares the attractive A-Frame appearance, its crucial technical superiority lies in the orientation of its panels: they run vertically, from the roof's peak down to the eaves. To accomplish this, an additional framework of purlins is installed underneath, adding a significant layer of strength and rigidity to the entire structure.

The primary advantage of the vertical roof is its flawless performance against the elements. The vertical orientation acts like a slide, allowing heavy rain, snow, and debris to shed directly off the roof. At Steel Building Stores, we strongly recommend the vertical roof for any building longer than 36 feet and for any customer in areas with severe weather. It is the smartest investment for maximum longevity and peace of mind.
