It’s essential to consult with a professional roofing contractor to determine the best choice for your specific needs.
The Importance of Choosing the Best Type of Flat Deck Roofing
Flat deck roofing is a type of roofing that, as the name suggests, is flat or nearly flat. It’s commonly used on commercial and industrial buildings but can also be found on some residential properties. Unlike sloped roofs, which allow water to run off easily, flat deck roofs require special attention and care to ensure proper drainage.
Without proper drainage, water can pool on the roof which can lead to leaks, mold growth, and other costly repair issues. Choosing the best type of flat deck roofing for your property is crucial to ensure that it remains in good condition for years to come.
With so many different types of flat deck roofing available on the market today, it can be challenging to know which one is best suited for your needs. The right type of flat deck roofing will depend on several factors, such as your budget, climate conditions in your area, and maintenance requirements.
Brief Explanation of What Flat Deck Roofing Is
Flat deck roofing systems are typically composed of a few different layers that work together to protect your building from the elements. The layers may include insulation materials like foam board or fiberglass batts; a vapor barrier layer that prevents moisture from seeping into the insulation; a protective layer like asphalt or modified bitumen that provides waterproofing; and finally, a top layer that may consist of gravel ballast or reflective coating. One common misconception about flat deck roofing is that it needs to be completely level – this isn’t necessarily true!
In fact, most building codes require some slope (typically 1/4 inch per foot) for drainage purposes. Other important considerations when designing a flat roof include wind uplift pressure (since there’s no slope for wind gusts to slide off), local climate conditions (e.g., heavy snowfall requires extra support), and building use (e.g., a rooftop garden may require additional structural support).

What is the Best Type of Flat Deck Roofing?
Flat deck roofing is a popular roofing option for commercial and residential buildings with flat or low-sloped roofs. Understanding the different types of flat deck roofing can help you make an informed decision when it comes to choosing the right type for your building. Built-Up Roofing (BUR)
Built-up roofing, also known as BUR, is a traditional flat roof system that has been around for over 100 years. BUR systems consist of several layers of asphalt and ply sheets applied directly to the roof deck. These layers are then topped with a layer of gravel or reflective coating to provide additional protection against the elements.
One advantage of BUR systems is their durability. They have been proven to last up to 30 years or more if properly maintained.
However, BUR systems can be heavy and require significant structural support. They also require regular maintenance and repair, which can be costly over time. Modified Bitumen Roofing (MBR)
Modified bitumen roofing, also known as MBR, is a hybrid between BUR and single-ply roofing systems. MBR systems consist of reinforced ply sheets that are modified with polymer additives to increase their durability and resistance to damage from UV rays. One advantage of MBR systems is their ease of installation compared to BUR systems.
They are lightweight and do not require as much structural support as other types of flat roof systems. However, they may not be as durable in harsh weather conditions compared to other flat roof systems. Single-Ply Membrane Roofing (SPR)
Single-ply membrane roofing, also known as SPR, is a relatively new type of flat roof system that has gained popularity in recent years due to its energy efficiency and ease of installation. SPR consists of a single layer of synthetic materials such as PVC or TPO placed directly onto the roof deck. One advantage of SPR systems is their energy efficiency.
They reflect sunlight, reducing the amount of heat absorbed by the building and lowering cooling costs. However, they may not be as durable as other types of flat roof systems and can be prone to damage from hail or debris.
There are several types of flat deck roofing systems available, each with its own advantages and disadvantages. When choosing a flat deck roofing system, it is important to consider factors such as durability, ease of installation, cost-effectiveness, energy efficiency, and maintenance requirements.
Built-Up Roofing (BUR)
The O.G. of Flat Deck Roofing
Built-Up Roofing (BUR) is the original gangster of flat deck roofing. It’s been around for over a century, and for good reason. BUR is made up of multiple layers of felt or fabric sheets that are saturated in bitumen and topped with a layer of gravel or other protective material.
This layered approach results in a thicker, more durable roof that can withstand harsh weather conditions and heavy foot traffic. One major advantage of BUR is its longevity.
A well-installed BUR roof can last up to 30 years with proper maintenance. That’s longer than most other types of flat deck roofing out there.
Additionally, BUR is fire-resistant, which adds an extra layer of safety to your building. However, all good things come with a catch.
The installation process for BUR can be time-consuming and messy since it requires heating up large amounts of bitumen on-site. Plus, the added weight from the layers can be problematic for older buildings that may not have been constructed to support such added weight.
Modified Bitumen Roofing (MBR)
The Middle Child
Modified Bitumen Roofing (MBR) is like the middle child – often overlooked but still worthy of attention and praise. This type of flat deck roofing combines traditional asphalt with modern materials like rubber or plastic modifiers to create a more flexible and stable product. MBR shares many similarities with BUR in terms of installation process and durability but has the added advantage of being less messy during installation due to its pre-manufactured nature.
Another benefit? MBR has superior resistance to punctures and tears compared to other types, thanks to the modifiers used in its creation.
However, MBR does have some downsides, too – namely, its limited lifespan compared to BUR and other types. MBR roofs typically last around 20 years and are more prone to cracking in extreme temperatures.
Single-Ply Membrane Roofing (SPR)
The New Kid on the Block
Single-Ply Membrane Roofing (SPR) is the new kid on the block when it comes to flat deck roofing types. Instead of multiple layers, SPR uses one single layer of material – usually made from PVC or TPO – that is heat-welded together at the seams.
One major advantage of SPR is its energy efficiency. The white surface reflects sunlight and reduces cooling costs during hot summer months.
Plus, SPR installation is relatively quick and clean compared to other types. However, there are some downsides to consider as well.
SPR can be prone to punctures and tears if not installed properly or if exposed to sharp objects like tree branches or debris. Additionally, since it’s a newer type of flat deck roofing, its long-term durability hasn’t been fully tested yet – so it may not be the best choice for those looking for a long-term investment in their building’s roof.
Rarely Known Small Details about Flat Deck Roofing Types
BUR’s Lifespan Compared to Other Types
Let’s get one thing straight: Built-Up Roofing (BUR) is not the best option for flat deck roofing. Sure, it may be cheaper in the short term, but do you really want to be replacing your roof every ten years? That’s right, BUR has a lifespan of just 10-15 years.
Compare that to Modified Bitumen Roofing (MBR) with a lifespan of 20-30 years and Single-Ply Membrane Roofing (SPR) with a lifespan of 25-35 years. But it’s not just about longevity.
BUR is also incredibly heavy and requires multiple layers to create a waterproof barrier. This means more labor costs and potential issues with structural integrity down the line.
And let’s not forget the environmental impact of having to replace your roof more frequently. In short, while BUR may seem like an attractive option due to its lower upfront cost, it ultimately ends up being more expensive and less sustainable in the long run.
MBR’s Resistance to Punctures and Tears Compared to Other Types
Modified Bitumen Roofing (MBR) is often overlooked when compared to newer options like Single-Ply Membrane Roofing (SPR). But MBR has one major advantage that makes it worth considering: its resistance to punctures and tears.
While SPR may have better energy efficiency ratings, it falls short in terms of durability. In areas with high foot traffic or falling debris, SPR can easily puncture or tear.
MBR, on the other hand, is designed with multiple layers that make it incredibly resistant to damage. So while SPR may be the trendy choice for eco-conscious homeowners, MBR shouldn’t be discounted for those who prioritize durability and longevity.
SPR’s Energy Efficiency Compared to Other Types
Single-Ply Membrane Roofing (SPR) is the darling of environmentally conscious homeowners. And for a good reason – it has some of the highest energy efficiency ratings of any flat deck roofing option.
But is it really worth the hype? While SPR certainly has its benefits, it’s important to consider the bigger picture.
Yes, SPR may save you money on energy bills in the short term. But what about in the long term?
What about the environmental impact of producing and installing SPR? When compared to options like Modified Bitumen Roofing (MBR), which has a longer lifespan and requires less maintenance, SPR may not be as sustainable as we’re led to believe.
In fact, MBR can even be recycled at the end of its lifespan. While Single-Ply Membrane Roofing (SPR) may seem like a no-brainer for eco-conscious homeowners, it’s important to consider all factors before making a decision on flat deck roofing.

The Best Type of Flat Deck Roofing: A Recap
After examining the different types of flat deck roofing, it’s clear that Single-Ply Membrane Roofing (SPR) is the best option for a number of reasons. While Built-Up Roofing (BUR) and Modified Bitumen Roofing (MBR) are popular options, they fall short in comparison to SPR when it comes to energy efficiency, lifespan, and overall durability.
SPR Reigns Supreme in Energy Efficiency
One of the most important factors to consider when choosing a flat deck roofing type is energy efficiency. In this aspect, SPR stands out as the clear winner. Unlike BUR and MBR, SPR is designed with reflective materials that effectively reduce heat absorption.
This means that your building will stay cooler in hot weather and require less air conditioning to maintain a comfortable temperature. Not only does this save you money on your energy bills, but it also reduces your carbon footprint.
Lifespan: Why BUR & MBR Fall Short
Another key factor to consider when selecting a flat deck roofing type is lifespan. After all, you don’t want to be replacing your roof every few years! Unfortunately for BUR and MBR supporters, these options simply can’t compete with SPR in terms of longevity.
While BUR can last up to 20 years with proper maintenance, it requires frequent upkeep which can add up over time. MBR has a similar lifespan but falls short when it comes to puncture resistance- meaning that it may need replacing even sooner if damaged by external factors.
Durability: The Final Factor
When it comes down to durability- an essential consideration for any investment like a roof- SPR emerges as the clear choice once again. Unlike BUR and MBR which both require routine maintenance upkeep just for basic protection against the elements, SPR is designed for long-term durability. It’s resistant to punctures and tears, and it has a reinforced structure that can withstand harsh weather conditions.
While BUR and MBR may be more affordable options upfront, they can end up costing more in repairs and replacements in the long run. Single-Ply Membrane Roofing (SPR) is undoubtedly the best option when it comes to flat deck roofing.
It’s energy-efficient, has an impressively long lifespan, and its durable structure guarantees protection against harsh weather conditions. While choosing SPR may come with a higher initial cost than other types of flat deck roofing- ultimately, it will save you money over time while providing superior quality and peace of mind knowing your roof is built to last.
