Single Ply Roof (Everything You Need To Know)

Roofing decisions are some of the most crucial choices you will make as a property manager. The right roofing solution can help you:

• Save on maintenance costs
• Improve energy efficiency
• Extend the lifespan of your building

One of the most popular options in today’s commercial roofingmarket is the single ply roof. This guide will provide you with all the essential information you need to evaluate whether a single ply roof is the right choice for your property.

What is a Single Ply Roof?

A single ply roof is a flat roofing solution that consists of flexible sheets of synthetic polymer material. These membranes are installed in a single layer, providing a waterproof barrier to protect buildings from the elements. There are two main types of single ply roofing membranes:

• Thermoplastic – These include TPO (Thermoplastic Polyolefin) and PVC (Polyvinyl Chloride) membranes. They can be welded together with heat, creating a strong, seamless bond.
• Thermoset – The most common type is EPDM (Ethylene Propylene Diene Monomer), which is known for its durability and resistance to UV radiation and ozone.

Benefits of Single Ply Roofs

Single ply roofing systems are a great choice for homeowners looking for optimal protection.

💰 Cost-Effectiveness

One of the major advantages of single ply roofs is their cost-effectiveness. The installation process is relatively straightforward, which can lead to lower labor costs. Additionally, the materials themselves are often less expensive compared to traditional roofing options.

💪 Durability and Longevity

Single ply roofing membranes are designed to withstand harsh weather conditions, including extreme temperatures, high winds, and heavy rainfall. Many single ply roofs come with warranties that range from 20 to 30 years, ensuring long-term protection for your property.

⚡️ Energy Efficiency

Thermoplastic single ply membranes like TPO and PVC are highly reflective, meaning they can reflect a significant amount of solar radiation. This helps to keep your building cooler and reduces the need for air conditioning, leading to lower energy costs.

🧘‍♀️ Flexibility and Versatility

Single ply membranes are highly flexible, making them ideal for roofs with complex designs or multiple penetrations. Their versatility allows them to be installed over a variety of substrates, including concrete, metal, and wood.

3 Types of Single Ply Roofing Membranes

When it comes to single ply roofing systems, you have options! Here’s how to choose between them.

1) TPO (Thermoplastic Polyolefin)

TPO is one of the fastest-growing segments in the commercial roofing industry. It combines the durability of EPDM with the performance of PVC. TPO membranes are known for their:

• Energy Efficiency – TPO is highly reflective and helps to reduce cooling costs.
• Durability – It offers excellent resistance to UV radiation, punctures, and chemical exposure.
• Environmentally Friendly – TPO is recyclable and does not contain chlorine or other harmful chemicals.

2) PVC (Polyvinyl Chloride)

PVC has been used in roofing for over half a century and is known for its strength and longevity. Key benefits of PVC roofing membranes include:

• Chemical Resistance – PVC is highly resistant to chemicals, making it ideal for industrial and commercial applications.
• Fire Resistance – PVC membranes are inherently fire-resistant due to their chlorine content.
• Flexibility – PVC remains flexible in a wide range of temperatures, making it suitable for various climates.

3) EPDM (Ethylene Propylene Diene Monomer)

EPDM is a synthetic rubber membrane that has been a staple in the roofing industry for decades. Its key attributes include:

• Durability – EPDM is known for its exceptional resistance to UV radiation, ozone, and weathering.
• Ease of Installation – EPDM can be installed using adhesives, mechanical fasteners, or ballasted systems.
• Cost-Effective – EPDM is often less expensive than other single ply options, making it a popular choice for budget-conscious property managers.

Installation Methods for Single Ply Roofs

The installation method for a single ply roof can vary depending on the type of membrane and the specific requirements of the project. Common installation methods include:

• Fully Adhered: In a fully adhered system, the membrane is glued directly to the substrate using a specialized adhesive. This method provides a strong bond and is ideal for roofs with irregular shapes or numerous penetrations.
• Mechanically Attached: In a mechanically attached system, the membrane is fastened to the substrate using screws and plates. This method is quick and cost-effective, but it may be less suitable for areas with high wind loads.
• Ballasted: In a ballasted system, the membrane is laid loosely over the substrate and held in place by a layer of gravel or pavers. This method is quick to install and ideal for large, flat roofs. However, it may require additional structural support to handle the weight of the ballast.

Maintenance and Repair of Single Ply Roofs

Single ply roofs are relatively simple to care for. Follow these steps to keep your roofing system in good shape.

• Regular Inspections: Regular inspections are crucial for maintaining the integrity of a single ply roof. Property managers should schedule inspections at least twice a year and after any major weather events. Look for signs of damage, such as punctures, tears, or seams that have come apart.
• Cleaning: Keeping the roof clean is essential for maintaining its reflectivity and preventing the buildup of debris that can cause damage. Use a gentle cleaning solution and a soft brush to remove dirt and grime.
• Repairs: Minor repairs, such as patching small holes or tears, can often be handled in-house. For more significant damage, it’s best to hire a professional roofing contractor who has experience with single ply membranes.

Environmental Impact of Single Ply Roofs

Sustainability

Many single ply roofing membranes are designed with sustainability in mind. TPO and EPDM, for example, are often recyclable at the end of their lifespan. Additionally, the energy-saving benefits of reflective single ply membranes contribute to a reduction in greenhouse gas emissions.

LEED Certification

Installing a single ply roof can contribute to a building’s LEED (Leadership in Energy and Environmental Design) certification. Reflective membranes, in particular, can earn points under the LEED rating system for their contribution to energy efficiency.

Green Roofing Systems

Single ply membranes can also be integrated into green roofing systems, which involve the installation of vegetation on the roof surface. Green roofs provide additional insulation, reduce stormwater runoff, and create habitats for wildlife.

Choosing the Right Single Ply Roof for Your Property

If you’re still not sure what the right roofing systems for your building is, you’ve come to the right place. We’re breaking down all of the facts that you need to know.

Assessing Your Needs

Before selecting a single ply roofing system, it’s important to assess the specific needs of your property. Consider factors such as:

• Climate – Some membranes perform better in certain climates. For example, TPO and PVC are ideal for hot, sunny areas, while EPDM is well-suited for colder climates.
• Building Use – The type of building and its use can influence the choice of membrane. Industrial facilities may benefit from the chemical resistance of PVC, while office buildings may prioritize energy efficiency.
• Budget – Determine your budget for both installation and long-term maintenance. While some membranes may have a higher upfront cost, their durability and energy-saving benefits can provide long-term savings.

Consulting with Professionals

Working with a professional roofing contractor or consultant can help ensure you select the best single ply roofing system for your property. They can provide expert advice on the most suitable membrane, installation method, and maintenance plan.
