1. Introduction to Flat Roofing
Flat roofs have become increasingly popular in both modern architecture and practical building design. Unlike their sloped counterparts, types of flat roofing systems create a nearly horizontal surface that maximizes usable space and offers unique esthetic appeal. At first glance, flat roofs might appear simple, but they actually come in several distinct varieties, each with specific benefits and applications.
Flat roofs and where they’re commonly used (residential, commercial, industrial).
Flat roofing systems appear across virtually every category of building construction. In residential settings, flat roofs are commonly found on modern and contemporary homes, particularly in urban areas where they provide valuable outdoor living space as rooftop decks or gardens. Additionally, many residential extensions and garages utilize different flat roof types to maintain visual harmony with existing structures.
Meanwhile, commercial buildings overwhelmingly favor flat roofing systems. Shopping centers, office buildings, and warehouses benefit from the cost-effective installation and maintenance that various types of flat roofing systems provide. The large surface areas of commercial structures make flat roofs particularly economical compared to pitched alternatives.
Industrial facilities represent another major application for flat roof covering types. Factories, processing plants, and manufacturing centers typically incorporate flat roofing for practical reasons – these buildings often house heavy HVAC equipment that requires the stable platform that only a flat roof can provide. Furthermore, the expansive nature of industrial complexes makes different types of flat roofing systems the logical choice from both construction and budgetary perspectives.
Importance of choosing the right type of flat roofing.
Selecting among the different flat roof types might seem straightforward, but this decision significantly impacts your building’s longevity, maintenance requirements, and overall performance. Each of the various types of flat roofing materials responds differently to weather conditions, temperature fluctuations, and UV exposure. Making an informed choice means understanding how these factors interact with your specific building needs.
Moreover, the right flat roofing system affects energy efficiency and environmental impact. Some types of commercial flat roofing feature reflective surfaces that minimize heat absorption, potentially reducing cooling costs by 15-25% during summer months. Others offer superior insulation properties that help maintain consistent indoor temperatures year-round.

2. Built-Up Roofing (BUR) Systems
Built-Up Roofing (BUR) stands as one of the oldest and most established types of flat roofing systems in the construction industry, with a track record spanning over 100 years. Often referred to as “tar and gravel” roofs, these time-tested systems remain a popular choice for many property owners seeking durability and reliable protection.
BUR layers (asphalt, tar, gravel)
The name “built-up” perfectly describes how these roofing systems are constructed through multiple layers that work together to create a watertight seal. Essentially, a traditional BUR system consists of alternating layers of reinforcing fabrics and waterproofing materials, typically assembled on-site.
The foundation of most BUR systems begins with several plies of roofing felt or fiberglass mat. Each layer gets saturated and bonded together using hot bitumen (asphalt or coal tar pitch) that’s heated to become fluid during application. This creates a membrane of three to five layers, though some high-performance applications might use more.
The final touch on many different types of flat roofing BUR systems is the surface layer, usually smooth river gravel, slag, or mineral granules embedded in a flood coat of bitumen. This top layer serves multiple purposes: it protects the underlying materials from UV rays, provides fire resistance, and adds beneficial weight to the system.
Pros and cons
As with all flat roof types, BUR systems offer distinct advantages and limitations:
Advantages:
- Exceptional durability with life spans ranging from 15 to 30+ years
- Superior waterproofing thanks to multiple redundant layers
- Excellent resistance to foot traffic and mechanical damage
- Low maintenance requirements once properly installed
- Strong fire-resistant properties, especially with gravel surfacing
Limitations:
- Heavier than many alternative flat roof covering types
- Installation generates strong odors and requires specialized equipment
- More labor-intensive installation process
- Less flexible in cold temperatures compared to newer alternatives
- Not ideal for easy identification of leaks when they do occur
Ideal applications and maintenance considerations
BUR systems perform exceptionally well on commercial buildings with large, open roof areas where their installation efficiency can be maximized. Schools, hospitals, and retail structures frequently utilize these types of commercial flat roofing solutions. They’re also ideal for roofs that experience regular foot traffic or require equipment installation.
Regarding maintenance, while generally low-maintenance, BUR systems benefit from regular inspections – ideally twice yearly and after severe weather events. Common maintenance involves clearing debris, checking flashings, and repairing any blistering or cracking in the membrane.

3. Modified Bitumen Roofing
Modified Bitumen (MB) represents a significant advancement in flat roofing technology, combining traditional materials with modern polymer science. As one of the most trusted types of flat roofing systems, Modified Bitumen offers property owners an excellent balance of performance and value that makes it worth considering for virtually any flat roof application.
Composition and application (torch-down or cold adhesive)
Modified Bitumen roofing consists of asphalt that has been enhanced with either SBS (Styrene-Butadiene-Styrene) or APP (Atactic Polypropylene) polymers. These additions significantly improve the natural properties of asphalt, creating a more versatile flat roof covering type. SBS modifiers provide rubber-like characteristics, enhancing flexibility, whereas APP modifiers create a plastic-like quality that increases UV resistance.
Installation of different types of flat roofing systems like Modified Bitumen typically occurs through one of two primary methods:
- Torch-down application: This traditional technique involves heating the underside of the membrane with a propane torch, melting the bitumen to create a secure bond with the substrate. Although effective, torch-down applications require skilled professionals due to fire safety concerns.
- Cold adhesive application: Increasingly popular, this method eliminates open flames by using specially formulated adhesives to bond the membrane. Cold application is safer and produces fewer odors, making it ideal for sensitive environments.
Advantages like flexibility and durability
Modified Bitumen offers several compelling benefits among different flat roof types:
- Superior flexibility and elongation properties, especially in SBS-modified products
- Exceptional resistance to thermal splitting and cracking in extreme temperatures
- Strong tensile strength from reinforcement materials (fiberglass or polyester)
- Factory-controlled thickness ensuring consistent quality
- Easier repairs compared to other types of flat roof systems
How it compares to BUR
Unlike conventional BUR systems, Modified Bitumen roofing typically requires fewer layers while still providing comparable protection. Moreover, MB systems generally weigh less than traditional BUR, potentially reducing structural requirements for new construction projects.
Another key difference lies in installation efficiency. Most Modified Bitumen roofs can be installed more quickly than equivalent BUR systems, potentially reducing labor costs and minimizing building disruption.

4. EPDM (Ethylene Propylene Diene Monomer) Rubber Roofing
Among the versatile types of flat roofing systems available today, EPDM (Ethylene Propylene Diene Monomer) stands out as a synthetic rubber membrane that has changed the commercial roofing landscape since its introduction in the 1960s. This single-ply roofing solution offers property owners exceptional performance across various applications.
Characteristics of EPDM membrane roofing
EPDM is composed of a synthetic rubber compound derived from oil and natural gas. Available in two standard colors, black and white this flat roof covering type comes in various thicknesses ranging from 45 to 90 mils (0.045 to 0.090 inches). Most installations utilize sheets 10 to 50 feet wide, which significantly reduces the number of seams compared to other flat roof types.
Installation methods for EPDM include fully-adhered systems where the membrane is attached with adhesive across the entire surface, mechanically-fastened approaches using plates and fasteners, and ballasted systems where the membrane is held in place with stone or pavers. The material remains flexible even in extreme temperatures, maintaining its integrity between -40°F and 300°F.
Benefits: cost-effective, UV resistance, long lifespan
EPDM offers remarkable value among different types of flat roofing systems. Initially, property owners appreciate the relatively low material and installation costs. Additionally, EPDM’s simple maintenance requirements further enhance its lifecycle affordability.
Perhaps most impressive is EPDM’s outstanding weather resistance. The material contains carbon black (in black membranes), providing superior protection against ultraviolet radiation and ozone. Consequently, EPDM demonstrates exceptional durability in harsh climates.
Longevity stands as another major advantage, properly installed EPDM roofs regularly last 25-30 years, with many exceeding 40 years with appropriate maintenance. This impressive lifespan stems from EPDM’s remarkable resistance to:
- Thermal shock and cycling
- Hail damage
- Wind uplift
- Punctures and tears
Common uses and considerations
EPDM remains popular for both commercial types of flat roofing and residential applications. It performs exceptionally well on large commercial buildings, warehouses, and industrial facilities where cost-effectiveness at scale matters. Indeed, many property owners select EPDM for its proven performance record in buildings with extensive roof areas.
Nevertheless, considerations include proper installation of seams, typically the vulnerable points in any EPDM system. Furthermore, black EPDM absorbs heat, potentially increasing cooling costs in warmer climates, though white EPDM options address this concern.

5. TPO (Thermoplastic Olefin) Roofing
In recent years, Thermoplastic Olefin (TPO) has emerged as a frontrunner among types of flat roofing systems in the commercial building sector. This single-ply membrane combines the durability of rubber with advanced polymer technology, creating a roofing solution that addresses many modern building challenges.
Features of TPO (energy efficiency, white reflective surface)
TPO roofing stands out primarily for its remarkable energy efficiency. The bright white surface effectively reflects UV rays rather than absorbing them, significantly reducing heat transfer into buildings. This reflective capability can help lower cooling costs by up to 15% for commercial buildings. The membrane consists of three critical layers: a TPO polymer base providing flexibility, a polyester-reinforced fabric center (scrim) offering strength, and a thermoplastic olefin top layer containing UV inhibitors and fire retardants.
Notably, TPO roofs typically come in white, light gray, or tan colors, all of which reflect sunlight rather than absorb it. This reflectivity not only reduces energy consumption but also helps combat the urban heat island effect, making TPO an environmentally responsible choice.
Why it’s growing in popularity
The National Roofing Contractors Association reports that TPO now claims approximately 40% of the commercial roofing market share. This dramatic growth stems from several advantages. TPO offers excellent value through its balance of performance and affordability. As a result, many property owners find TPO delivers comparable benefits to more expensive flat roof types at a more accessible price point.
The environmental benefits further boost TPO’s appeal. These roofing membranes are recyclable and often chlorine-free, supporting sustainable building practices and potentially contributing to LEED certification credits. Their energy-saving properties also translate into a smaller environmental footprint.
Installation and durability
Despite its relatively recent introduction to the roofing industry, TPO demonstrates impressive durability characteristics. A properly installed and maintained TPO roof typically lasts between 20-30 years. The installation process involves preparing the existing roof, adding insulation (commonly polyisocyanurate), applying a cover board, and then installing the TPO membrane itself.
TPO installation methods include mechanically fastened systems using fasteners and plates, fully adhered systems using adhesives, or self-adhered TPO roofing materials. The seams are heat-welded to create watertight seals that are three times stronger than conventional rubber roofs using tape systems.

6. PVC (Polyvinyl Chloride) Roofing
PVC (Polyvinyl Chloride) roofing has established itself as a premier option among types of flat roofing systems for property owners seeking exceptional chemical resistance and durability. This thermoplastic single-ply membrane offers unique performance characteristics that make it worth considering for many commercial applications.
What makes PVC roofing stand out (chemical resistance, seam strength)
PVC roofing earns its reputation primarily through outstanding chemical resistance. Unlike other flat roof types, PVC membranes remain unaffected by most oils, greases, and industrial chemicals that would deteriorate alternative materials. This resistance makes it ideal for restaurant roofs, manufacturing facilities, and other buildings where chemical exposure is common.
Alongside chemical resistance, PVC’s hot-air welded seams provide remarkable strength, typically stronger than the membrane itself. The thermoplastic nature of PVC enables these welds to create essentially one continuous sheet across the entire roof, virtually eliminating the seam failures common with adhesive-based systems.
Additionally, PVC membranes typically contain plasticizers that deliver excellent flexibility and puncture resistance, ensuring the material can accommodate building movement without compromising waterproofing integrity.
Typical commercial applications
PVC flat roofing excels in several commercial scenarios, primarily:
- Restaurants and food service facilities where grease exposure occurs
- Hospitals and healthcare facilities requiring chemical resistance
- Manufacturing plants with industrial emissions
- Buildings in coastal areas exposed to saltwater
The material’s inherent fire resistance, even self-extinguishing properties, makes it particularly valuable for facilities with strict safety requirements. Many types of commercial flat roofing applications benefit from PVC’s ability to remain watertight even under prolonged standing water conditions.
Comparisons to TPO and EPDM
Compared to TPO, PVC typically offers superior chemical resistance and longer-established performance history, albeit usually at a higher price point. Conversely, PVC membranes demonstrate greater flexibility than most TPO products, particularly in colder temperatures.
Against EPDM, PVC provides better hot-air welded seams instead of tape or adhesive systems. However, EPDM generally costs less initially and offers simpler installation processes for certain flat roof covering types applications.
