Single-ply roofing vs. built-up roofing: Which is Best for Commercial Properties?

Choosing the right roofing system can feel overwhelming, especially when comparing popular options like Single-Ply and Built-Up Roofing (BUR). Both are widely used for commercial buildings, but they offer different benefits in terms of durability, cost, and maintenance.

Are you looking for a quicker installation or a more time-tested, layered protection? Understanding the differences can help you make a smarter investment for your property. Let’s break down these Single-ply roofing vs. built-up roofing options to help you decide which one suits your needs best.

Importance of Choosing the Right Roofing System for Commercial Buildings

Selecting the right roofing system is crucial for commercial buildings as it impacts durability, energy efficiency, and maintenance costs. A well-suited roof can protect the building from weather damage and reduce long-term expenses.

Introduction to Single-ply roofing vs. built-up roofing(BUR)

Two common flat roofing options are Single-ply roofing vs. built-up roofing (BUR). Both offer unique benefits and are widely used for commercial structures.

Single-Ply Roofing

What is Single-Ply Roofing?

Single-ply roofing consists of flexible sheets of synthetic material designed for flat roofs. It provides a lightweight, cost-effective solution with good weather resistance.

Types of Single-Ply Membranes:

TPO (Thermoplastic Polyolefin): Known for energy efficiency and heat reflection.
EPDM (Ethylene Propylene Diene Monomer): A durable synthetic rubber with strong weather resistance.

Installation Methods:

Adhered: Fully bonded to the roof deck using adhesives.
Mechanically Fastened: Secured with screws and plates.
Ballasted: Held in place with gravel or pavers for weight.

Built-Up Roofing (BUR)

What is Built-Up Roofing?

BUR consists of multiple layers of bitumen and reinforcing fabrics, creating a thick, durable roof system.

Layers in a BUR System:

Base Layer: Applied directly on the roof deck.
Bitumen Layer: Alternating layers of asphalt or tar.
Reinforcing Fabric: Enhances strength and flexibility.

Final Surfacing Options:

Gravel: Provides UV protection and fire resistance.
Stone: Enhances durability and impact resistance.

Key Question: Which system suits your building’s climate and long-term goals best?

Comparative Analysis: Single-ply roofing vs. built-up roofing

When choosing a roofing system for your commercial property, it’s important to understand the key differences between Single-ply roofing vs. built-up roofing (BUR). Here’s a simple breakdown to help you decide.

Installation Process

Single-Ply Roofing:
This system is faster to install since it involves fewer layers. It’s a great choice when you need a quicker roofing solution.
Built-Up Roofing (BUR):
BUR takes longer to install because it involves multiple layers of materials, making the process more labor-intensive. However, the extra layers provide additional protection.

Which one suits your timeline better?

If you’re on a tight schedule, Single-Ply might be ideal. For a more durable, time-tested option, BUR could be worth the wait.

Durability and Lifespan

Single-Ply Roofing:
With proper maintenance, Single-Ply roofs can last up to 30 years. They’re durable but may not last as long as BUR.
Built-Up Roofing (BUR):
BUR can exceed 40 years of service, thanks to its multiple protective layers.

Looking for a long-term investment?
BUR tends to be a more durable choice if you prioritize longevity.

Cost Considerations

Single-Ply Roofing:
Generally, Single-Ply roofing has lower upfront costs, making it budget-friendly for initial installations.
Built-Up Roofing (BUR):
BUR requires a higher initial investment due to labor and materials but can save on maintenance costs over time.

What’s your budget like?
If you’re working with limited upfront funds, Single-Ply is a great choice. For long-term savings, BUR could pay off in the future.

Maintenance Requirements

Single-Ply Roofing:
Regular inspections are necessary to monitor seams and prevent leaks. Maintenance is simpler but more frequent.
Built-Up Roofing (BUR):
BUR needs periodic maintenance, mainly to keep the top gravel layer intact. Its multi-layer build makes it naturally more resistant to wear and tear.

How often do you want to worry about roof maintenance?
If you prefer minimal ongoing work, BUR might be a better choice despite its higher initial cost.

Performance in Different Conditions

Single-Ply Roofing:
Excellent at resisting UV radiation and chemicals, making it ideal for areas with high sun exposure or industrial settings.
Built-Up Roofing (BUR):
Superior for extreme weather conditions due to its extra layers, offering better protection in storms, hail, and heavy rain.

Does your area experience harsh weather?
BUR might be the better option if your region faces extreme weather patterns regularly.

Benefits of Built-Up Roofing (BUR)

Why choose BUR? Here are some standout advantages:

Proven Track Record: Over a century of reliable use in the U.S.
Waterproof Surface: The seamless design minimizes leak risks.
UV and Fire Protection: Excellent resistance against UV rays and fire hazards.
Low Maintenance: Once installed, it requires minimal upkeep compared to other systems.

Exploring Other Commercial Roofing Options

When it comes to commercial roofing, there are more choices beyond Single-Ply and Built-Up Roofing (BUR). Let’s explore two other reliable options that might be the right fit for your property.

1. Modified Bitumen Roofing

Modified Bitumen is like a modern upgrade of BUR, combining its durability with added flexibility.

Flexible Yet Strong: The materials used allow it to expand and contract, making it ideal for changing weather conditions.
Built for Foot Traffic: If your roof will experience regular foot traffic, this option holds up well under pressure.
Durability: Like BUR, it offers long-term protection with minimal maintenance.

Is your building in a high-traffic area?
If your roof needs to handle regular activity, Modified Bitumen could be a solid choice.

2. Metal Roofing

Metal roofing is another excellent choice for commercial properties, known for its strength and longevity.

Exceptional Lifespan: Metal roofs can last over 50 years with proper care.
Fire Resistance: Naturally resistant to fire, making it ideal for safety-focused properties.
Energy Efficient: The reflective surface helps reduce heat absorption, lowering cooling costs in summer.

Looking for a low-maintenance, energy-saving solution?
Metal roofing not only lasts long but also contributes to lower energy bills.

Factors Influencing Roofing Material Choice

Choosing the right roofing material involves more than just appearance or cost. Here are key factors to keep in mind:

Building Structure and Design

Is your roof flat or sloped?
Does the design support heavier materials like BUR, or do you need something lightweight like Single-Ply?

Climate and Environmental Conditions

Does your area face heavy rainfall, extreme heat, or frequent storms?
Some materials handle harsh weather better than others—BUR and Metal Roofing are great for extreme conditions.

Budget Constraints and Long-Term Costs

Can you invest more upfront for a durable system like BUR or Metal Roofing?
Or do you need a cost-effective, quicker solution like Single-Ply?

Maintenance and Facility Usage

Will the roof require regular maintenance?
Is it easy to access for inspections, or does it need to withstand heavy foot traffic?

Final Thought:

Its all about Single-ply roofing vs. built-up roofing. Every roofing material offers unique benefits. The right choice depends on your building’s needs, climate, and budget. If you’re unsure, consulting a professional can help you make the best long-term decision for your commercial space. Which roofing type fits your property best?

FAQs

What is the difference between a built-up roof system and a single-ply roof system?

A built-up roof (BUR) consists of multiple layers of bitumen and reinforcing fabric, making it thicker and more durable. Single-ply roofing uses a single membrane layer, making it lighter and faster to install but less layered than BUR.

What are the disadvantages of single-ply roofing?
Single-ply roofs can be more prone to punctures and damage from sharp objects due to their single-layer design. They may also require regular inspections to prevent seam issues and leaks.

What is single-ply roofing?
Single-ply roofing is a flat roof system made from a single synthetic membrane, such as TPO, PVC, or EPDM. It’s commonly used in commercial buildings for its ease of installation and flexibility.

Is single-ply roofing any good?

Yes, single-ply roofing is a reliable option due to its cost-effectiveness, flexibility, and UV resistance. However, it works best when installed correctly and maintained regularly.
