Commercial Roof Types

The 9 Types of Commercial Roofs Explained

Selecting an appropriate roofing system for a commercial building is crucial in ensuring the structure's performance and longevity. With the Midwest's hot, humid summers, heavy storms, and cold winters, the choice of roofing material becomes even more significant. Here, we explore nine common commercial roofing types, along with their strengths and weaknesses.

1. Single-Ply

The Pros of Single-Ply Roofing

Energy Efficiency: Single-ply roofing materials often come in reflective or white surfaces that can significantly reduce a building's cooling costs. These materials reflect sunlight, helping to maintain a more stable indoor temperature, which can result in energy savings.

Single-ply roofing is a popular choice for commercial and industrial buildings, and for good reason. This roofing type offers several advantages that make it a practical and cost-effective option. Let's explore some of the key benefits of single-ply roofing.

Ease of Maintenance: Maintaining single-ply roofing is relatively simple. Regular inspections and minor repairs can extend the roof's lifespan, ensuring it continues to perform effectively.

Lightweight: Single-ply roofing is lightweight compared to many other roofing systems. This feature reduces the load on the building's structure, making it ideal for designs that can't support heavier roofing materials.

Installation Speed: Installing single-ply roofing is generally faster compared to other roofing systems. The sheets come in large rolls or sheets, which can be quickly and easily applied, reducing labor costs and minimizing disruption to building occupants.

Waterproofing: Single-ply roofing materials are excellent waterproofing agents. They create a seamless, watertight barrier over the roof that effectively prevents leaks and water damage.

Durability: These roofing materials are designed to withstand the elements and last for many years. They can resist UV radiation, ozone exposure, and extreme weather conditions, making them a long-lasting choice.

2. PVC

Benefits of PVC Roofing

Durability and Longevity

PVC roofing is renowned for its robust nature, capable of withstanding harsh weather conditions, including heavy rain, strong winds, and extreme temperatures. With proper maintenance, a PVC roof can last over 20 years.

Energy Efficiency

The reflective properties of PVC membranes reduce heat absorption, making them an energy-efficient option. This can lead to significant savings on cooling costs, especially in warmer climates.

Chemical Resistance

PVC roofing is resistant to various chemicals, making it an ideal choice for commercial facilities that may encounter chemical exposure, such as airports, restaurants, and manufacturing plants.

Fire Resistance

PVC membranes are naturally fire-resistant, providing an additional layer of safety for your building.

Eco-Friendly Options

Many PVC roofing systems are recyclable and can contribute to LEED credits, supporting environmentally conscious building practices.

3. TPO

Key Benefits of a TPO Roof

Affordability

One of the most compelling advantages of TPO roofing is its cost-effectiveness. Compared to other roofing materials, TPO offers a lower initial investment, making it an attractive option for those who need a budget-friendly solution without compromising on quality or performance.

Heat Reflection

TPO roofing is known for its excellent heat-reflective properties. The reflective surface of TPO membranes helps to reduce the building's heat gain, which can lead to significant energy savings, especially during hot summer months. This characteristic not only reduces cooling costs but also contributes to the overall comfort of the building's interior environment.

Damage Resistance

Durability is a hallmark of TPO roofing. The membrane is crafted to withstand a variety of environmental challenges, including wind, rain, and UV radiation. Its resistance to punctures, tears, and impacts ensures that it remains intact and effective over time, minimizing repair and maintenance costs.

Long Service Life

With proper installation and maintenance, TPO roofing can deliver a long service life, lasting up to 20-30 years. This longevity is a testament to its robust design and resilience, providing building owners with peace of mind and a reliable roofing solution.

4. EPDM

EPDM (Ethylene Propylene Diene Terpolymer) is often referred to as the “original” single-ply membrane and is known to last up to 40 years. Like TPO, EPDM is manufactured in rolls of various widths and thicknesses.

EPDM is constructed from a rubbery material and has been considered a trustworthy option for years. EPDM roofing membrane has a proven track record of being a cost-effective, long-lasting, environmentally friendly option (100% recyclable).

Durability: EPDM roofs are known for their long lifespan and ability to withstand extreme weather conditions.

Flexibility: This material remains flexible even in low temperatures, reducing the risk of cracks and leaks.

Why Choose EPDM?

Energy Efficiency: EPDM roofing reflects heat, helping to maintain a comfortable temperature inside your building and potentially reducing energy costs.

Environmentally Friendly: Made from recycled materials, EPDM is an eco-friendly option for environmentally conscious businesses.

5. Built-Up Roof

Pros of Built-Up Roofing:

Built-Up Roofing (often called “tar and gravel roofs”) has been used in the U.S. for over 100 years, making it one of the oldest and most proven commercial roofing systems.

A Built-Up Roof consists of multiple layers of asphalt (bitumen) alternated with reinforcing plies, finished with a gravel or mineral cap sheet. A common hybrid variation includes a modified bitumen cap sheet for additional flexibility and performance.

• Excellent waterproofing protection

• Multiple layers provide redundancy and durability

• Fire-resistant assemblies available

• UV protection from gravel or mineral surface

• Handles heavy foot traffic better than many membranes

• Withstands harsh weather when installed and maintained properly

• Expected lifespan: 20–30 years with proper installation and maintenance

6. Spray Foam

Whether you're embarking on a new construction project or dealing with a leaky roof that has troubled you for years, Adviser1 offers a revolutionary solution to meet your needs. Our spray foam roofing system provides a long-term, cost-effective answer that not only resolves existing issues but also saves you money in the long run.

What Is a Spray Foam Roof?

A spray foam roof is a unique roofing system that involves applying a mixture of liquid chemicals that expand into a foam once sprayed onto your roof. This foam hardens to form a solid, seamless surface that offers exceptional protection and insulation.

Leak Prevention: The seamless application of spray foam prevents water from seeping through joints or seams, effectively putting an end to persistent leaks.

Key Benefits of a Spray Foam Room

Durability: Spray foam roofs are known for their resilience and longevity. They can withstand harsh weather conditions and maintain their integrity for decades when properly maintained.

Energy Efficiency: By providing excellent insulation, spray foam roofs help regulate the temperature inside your building, reducing the need for excessive heating or cooling and thus lowering energy bills.

Environmentally Friendly: The insulation properties of spray foam reduce energy consumption, contributing to a smaller carbon footprint.

Cost Savings: Although the initial cost may be higher than traditional roofing materials, the long-term savings on energy and maintenance make it a wise investment.
