Commercial Types of Roofs

Your roof might not be the first thing on your mind, but it says a lot about your business and its image. What does your roof say about you?

Commercial roofs come in various shapes and sizes, each reflecting the unique character of the businesses they shelter. At The Roofing Center, we offer a range of roofing types and materials that cater to various budgets and styles, ensuring your roof matches your business’s identity.

Here are the three main categories defining your commercial roof type:

Commercial Roof Materials

Metal Roofs

To safeguard everything under your business’s roof, metal roofing is one of the most durable options. At The Roofing Center, we enhance its life with periodic elastomeric coatings that prevent rust and galvanization. The life of a metal roof is up to 50 years.


In the single-ply family, thermoplastic roofing (TPO) is perfect for flat roofs. TPO sheets are heat-welded, creating an impenetrable shield against the elements. It’s also resistant to most chemicals, with a lifespan of 20-30 years.

Single-ply Membrane

Our single-ply membrane is an excellent choice for a long-lasting, cost-effective, and low-maintenance roof. Torch-free installation ensures excellent performance under various weather conditions. Our white and tan options boast high reflectivity, earning them Energy Star approval. Standard color choices include black and grey, with a lifespan of 20-35 years.


Thermoplastic PVC roofing is incredibly robust, with heat-welded seams forming a permanent, watertight bond stronger than the membrane. PVC is often known as “Alfa Romeo” of single-ply membranes, boasting a lifespan of approximately 25-35 years.


This synthetic rubber is highly heat and water-resistant, making it ideal for flat roofs with an optimistic pitch to prevent water accumulation. EPDM offers a lifespan of 25-35 years.

At The Roofing Center, we make choosing the right commercial roof easy. Your roof will not only protect your business but also reflect its culture.

Commercial Roof Styles

Choosing the right roof style for your business is like finding the perfect suit – it should reflect your business’s identity and serve its needs. Let’s break down some common commercial roof styles to help you decide:


Gable Roofs

Gable roofs, shaped like an upside-down V, are more common in residential areas.


Shed Roofs

Imagine a flat roof with a slight pitch – that's a shed roof. Perfect for warehouses and small business additions, it balances simplicity and functionality.


Folded Plate Roofs

Think of folded plate roofs as a series of gable roofs nestled side by side, like an accordion. They're frequently seen in commercial buildings like warehouses, libraries, or convention centers.


Hip Roofs

Hip roofs have four sloping sides without vertical roof lines. While commonly found in homes, they also grace some commercial properties. Their design involves a more intricate truss and rafter structure.


A-Frame Roofs

A roof with steep angles forming the shape of the letter 'A.' This style is popular with churches, small businesses, and restaurants. It adds a touch of uniqueness to your business's appearance.

These are just a few roof styles, with more to explore. At Roofing Center, we’re here to guide you in making the best choice for your business’s roofing needs. Let’s find the perfect fit together.

Understand your Commercial Roof's Pitch

When planning additions, renovations, repairs, or replacements for your business’s roof, knowing its pitch or angle is crucial. Here’s how you can gauge it:


Roof Pitch Defined

Your roof's pitch measures the vertical rise for every 12 inches of horizontal extension. For instance, if your roof ascends 8 inches over 12 inches of flat run, it has an 8-in-12 pitch.


Flat Roof

Anything with a pitch below 2-in-12.


Low Slope Roof

Ranging from 2-in-12 to 4-in-12 pitch.


Steep Slope Roof

Anything above 4-in-12 pitch, typically up to 21-in-12.

Understanding your roof’s pitch helps you make informed decisions about maintenance and improvements. At The Roofing Center, we’re here to assist you in every aspect of your roofing needs in St. Louis, St. Charles, St. Peters, and surrounding areas.
