What is Rubber Roofing?

Rubber roofing is a durable, waterproof roofing system typically made from EPDM (ethylene propylene diene monomer), a flexible, synthetic rubber material designed for low-slope or flat roofs. It is widely used in commercial and industrial buildings, thanks to its ability to withstand extreme weather, UV exposure, and thermal expansion.

Unlike traditional asphalt or metal roofs, EPDM is installed in large seamless sheets, minimizing leak points and simplifying maintenance. Its flexibility makes it especially effective in climates with temperature fluctuations, such as North Iowa, where freezing winters and hot summers demand resilient materials.

Rubber roofing is favored for:

• Commercial buildings with flat or low-pitch roofs
• Warehouses, office complexes, and retail spaces
• Garages, sheds, and utility structures

With a lifespan of 30–50 years and minimal maintenance requirements, rubber roofing remains one of the most cost-effective solutions for protecting commercial properties.

Best Uses for Rubber Roofing

Rubber roofing is a smart, versatile solution, but it’s not ideal for every property type. It excels in specific use cases where its waterproofing capabilities, durability, and cost-efficiency make it a top choice. Below are the situations where rubber roofing performs best.

1. Flat and Low-Slope Roofs

Rubber membranes like EPDM and TPO are designed specifically for flat or low-pitch roofs, where water runoff is slower. Traditional shingles are not suitable for these roof types due to their tendency to trap moisture.

Rubber roofing provides a seamless, watertight barrier ideal for preventing leaks in flat roof systems.

2. Commercial and Industrial Buildings

Because of its long lifespan, ease of installation, and low maintenance, rubber roofing is widely used on:

• Office buildings
• Warehouses
• Retail centers
• Apartment complexes

For large roof surfaces, EPDM offers an affordable and durable solution.

3. Garages, Sheds, and Outbuildings

Smaller structures like detached garages and utility buildings often have flat or slightly pitched roofs, making them ideal candidates for rubber roofing.

This is an economical way to extend the life of an outbuilding without overspending on materials.

4. Green Roof Systems

EPDM and TPO membranes are often used as the base waterproofing layer in green roof systems, where plants and soil are placed over the structure.

Rubber provides an impermeable barrier that protects the building from root penetration and moisture intrusion.

5. Rooftop HVAC and Equipment Areas

Rubber roofs are ideal for commercial buildings that require rooftop mechanical systems. They can support heavy equipment, and protective pads can be added to reduce puncture risks from maintenance traffic.

This makes them a durable and functional solution for utility-heavy structures.

Benefits of Rubber Roofing for Commercial Properties

Rubber roofing, particularly EPDM (ethylene propylene diene monomer), is a widely used solution for commercial buildings due to its proven performance, low life-cycle cost, and environmental benefits. Below are the key advantages that make it a smart investment for flat and low-slope commercial roofs.

1. Durability That Stands the Test of Time

EPDM roofs are known for their exceptional longevity, lasting 30 to 50 years when properly installed and maintained. Unlike traditional roofing materials, rubber resists:

• Cracking and blistering from UV exposure
• Damage from hail, wind, and standing water
• Thermal expansion and contraction in extreme climates

For commercial properties in regions like North Iowa, where temperature swings and storm conditions are common, this resilience can reduce repair costs and downtime over the long term.

2. Cost-Effective Over the Roof’s Lifetime

Rubber roofing delivers value at every stage:

• Lower installation costs due to fewer seams and easier application
• Minimal maintenance requirements compared to metal or asphalt systems
• Reduced repair frequency thanks to puncture-resistant properties and long-term performance

Though upfront pricing may vary, EPDM often provides the best return on investment (ROI) over the life of the roof.

3. Environmentally Friendly and Fully Recyclable

Sustainability is a growing priority in commercial construction. EPDM meets that need with:

• Roofing material made from recycled rubber
• Fully recyclable membranes at the end of life
• Low manufacturing impact compared to synthetic or petroleum-based alternatives

This makes rubber roofing an excellent choice for companies pursuing green building certifications or looking to reduce their environmental footprint.

4. Energy-Efficient Options Available

White or light-colored EPDM and TPO membranes offer high solar reflectance, helping reduce heat absorption on sunny days. This can result in:

• Lower cooling costs in summer
• Improved insulation when paired with the right underlayment
• Support for LEED credits and energy efficiency benchmarks

In colder climates, traditional black EPDM can help retain heat during winter months, which is beneficial for North Iowa properties.

5. Quick and Simple Installation Process

Rubber roofing comes in large rolls, allowing for faster, cleaner installations than tile, built-up roofing, or metal panels. This means:

• Fewer seams, reducing the potential for leaks
• Less disruption to daily business operations
• Easier access for future inspections and maintenance

Professional installation ensures a watertight seal and maximizes the material’s performance.

Types of Rubber Roofing Systems

You have options, when it comes to installing a rubber roof! Here are the different styles of a rubber roofing system you can choose from:

Fully Adhered System

In a fully adhered system, the EPDM membrane is glued directly to the insulation or substrate using a special adhesive. This method offers a smooth appearance and excellent wind resistance, making it a popular choice for many commercial applications.

Mechanically Attached System

A mechanically attached system involves securing the EPDM membrane to the roof deck using fasteners and plates. This method is quicker and more cost-effective to install, but it may be more prone to wind uplift compared to fully adhered systems.

Ballasted System

In a ballasted system, the EPDM membrane is laid loosely over the roof structure and held in place by a layer of ballast, usually gravel or pavers. While this method is quick to install and allows for natural expansion and contraction, it requires a structurally sound building capable of supporting the additional weight.

Drawbacks of Rubber Roofing

Rubber roofing, particularly EPDM and TPO, offers notable benefits like durability and low maintenance. However, it’s not without its limitations. Understanding the potential drawbacks can help property owners make an informed decision, especially when evaluating roofing systems for commercial or flat-roof applications.

1. Aesthetic Limitations

Rubber roofing often lacks the visual appeal of other materials. Most EPDM roofs are black and flat in appearance, which works well for industrial and commercial properties but may not suit more prominent or decorative buildings.

• TPO and PVC are available in lighter colors, but they tend to come at a higher initial cost.

2. Risk of Punctures

While rubber membranes are generally durable, they can be vulnerable to punctures from sharp debris, hail, or foot traffic. Tools or equipment dropped during maintenance can also damage the surface.

• Installing walk pads and performing routine inspections can help reduce this risk.

3. Seams Can Be a Weak Point

Rubber roofing is typically installed in large rolls that are sealed at the seams. Over time, exposure to UV rays and fluctuating weather conditions can compromise these seams, leading to leaks if not properly maintained.

• Seam failure is one of the most common causes of leaks on aging rubber roofs.

4. Requires Skilled Installation

Installing a rubber roof is not a DIY friendly project. It requires specialized tools, adhesives, and proper surface preparation. Mistakes during installation, such as improper sealing or poor drainage design, can shorten the roof’s lifespan.

• Working with an experienced commercial roofer is required for long-term performance.

5. Higher Initial Costs (Compared to Asphalt)

Rubber roofing typically costs more upfront than asphalt shingles. However, it often lasts longer and has lower maintenance requirements, making it more cost-effective over time.

• This may be a consideration for budget-conscious property owners with smaller buildings.

6. Heat Absorption and Reflectivity

Black EPDM absorbs heat, which may increase cooling costs in warmer seasons. Although white TPO offers better solar reflectance, it is more rigid in colder climates and can be more expensive.

• In colder regions like North Iowa, EPDM remains a practical and proven solution due to its cold-weather flexibility.

The 5-Step EPDM Rubber Roofing Installation Process

Curious what to expect when installing an EPDM rubber roof? While every project may vary slightly, here’s a reliable breakdown of the process so you know what’s involved and why each step matters.

1. Surface Preparation

Before any rubber is rolled out, the roofing crew starts with a clean foundation. This includes:

• Removing old roofing materials (if needed)
• Inspecting and repairing the roof deck for rot or damage
• Installing insulation or a cover board to improve energy efficiency and membrane support

A properly prepped surface is key to a smooth, long-lasting install.

2. Laying Out the Membrane

Next, the EPDM membrane is rolled out across the surface. It’s allowed to “relax” for a short period so it can lay flat without tension. Proper alignment at this stage ensures:

• Tight seams
• Minimal waste
• Even coverage across the roof

3. Securing the Membrane

Depending on the system chosen, the membrane is attached using one of three methods:

• Fully adhered (glued down)
• Mechanically fastened (with screws and plates)
• Ballasted (held in place with stone or pavers)

Each method has its advantages, and your contractor will recommend the best option based on your building type and roof design.

4. Seaming the Sheets

Where two sheets meet, they’re joined using seam tape or specialized adhesive. This creates a waterproof bond that’s critical to keeping moisture out. Poor seam work is one of the most common causes of leaks, so this step is done with great care and precision.

5. Final Detailing and Flashing

To finish the job, installers seal around all the tricky spots, such as:

• HVAC units
• Drains and vents
• Skylights
• Roof edges and terminations

High-quality flashing ensures the system remains watertight and performs well under harsh weather conditions.

Maintenance and Repairs

Rubber roofing is low-maintenance, but regular inspections and minor repairs are necessary to ensure its longevity and performance.

• Regular Inspections: Conduct regular inspections, especially after severe weather events. Look for signs of damage, such as tears, punctures, and seam separation. Address any issues promptly to prevent further damage and costly repairs.
• Cleaning: Keep your rubber roof clean by removing debris, leaves, and dirt that can trap moisture and cause damage. Gently wash the surface with mild soap and water as needed to prevent algae and mold growth.
• Repairs: Most minor damage, such as small tears or punctures, can be repaired with a patch kit designed for EPDM roofing. Follow the manufacturer’s instructions carefully to ensure a seamless repair. For more extensive damage, consult a professional roofing contractor.

Cost Considerations

If you’re concerned about the cost of rubber roofing, it helps to look at both the upfront investment and the long-term value it provides.

Initial Installation Costs

Rubber roofing typically costs between $5 and $10 per square foot, including materials and labor. Pricing can vary depending on:

• The size and complexity of your roof
• The condition of the existing roof
• Your geographic location and labor rates

While the initial cost may be higher than asphalt shingles, it’s often lower than metal roofing and requires fewer materials and seams, especially for flat or low-slope commercial roofs.

Long-Term Value

What rubber roofing lacks in low upfront pricing, it makes up for in long-term savings:

• Fewer repairs due to strong weather resistance
• Lower maintenance costs over decades
• Energy savings from reflective or insulated membranes
• Lifespan of 30-50 years, reducing the need for early replacement

When you factor in these savings, rubber roofing becomes a cost-effective choice for commercial buildings looking to reduce total roofing expenses over time.
