When it comes to protecting your commercial property, the roof you choose is one of the most critical decisions you’ll make. A commercial roof is not just about covering a building—it’s about safeguarding your assets, ensuring energy efficiency, and complying with local safety standards. Among the various roofing options available, some materials and systems are more widely used due to their cost-effectiveness, durability, and ease of installation. So, what is the most common type of commercial roof in Northampton?
In the UK and many parts of the world, flat and low-slope commercial buildings tend to use single-ply membrane systems. Among these, EPDM roofing, or Ethylene Propylene Diene Monomer, is currently one of the most commonly installed commercial roofing systems. Let’s explore why this type stands out, and how it compares with other popular options in the commercial roofing sector.
Why EPDM is the Go-To Commercial Roofing Choice
EPDM is a synthetic rubber roofing membrane that has gained popularity due to its excellent performance in various climates, including the wet and windy conditions often experienced in Northampton. It is typically installed on flat or low-slope roofs, which are the most common types found on commercial properties such as warehouses, office buildings, retail units, and schools.
One of the key reasons for the widespread use of EPDM is its impressive durability. When properly installed and maintained, an EPDM roof can last for 20 to 30 years or more. The material is resistant to UV radiation, ozone, and harsh weather conditions, making it a reliable choice for long-term protection.
Another reason for EPDM’s popularity is its ease of installation. The material is lightweight and available in large sheets, which reduces the number of seams. Fewer seams mean fewer potential points for water ingress, lowering the likelihood of leaks over time. Installation can be done using adhesives, mechanical fasteners, or ballast, depending on the building’s structure and requirements.
Cost-Effectiveness and Maintenance Benefits
Budget is always a major factor when selecting a roofing system. EPDM stands out as a cost-effective option, not only in terms of initial installation but also in its long-term maintenance requirements. Unlike some roofing materials that require regular sealing or specialised treatment, EPDM typically needs only periodic cleaning and inspections. This keeps maintenance costs low and reduces the likelihood of unexpected repair bills.
Additionally, the flexibility of the material allows it to accommodate structural movement, temperature shifts, and building settling without cracking or tearing. This characteristic further extends its lifespan and reliability, especially on buildings that experience vibration or slight movement.
Other Common Commercial Roofing Systems
While EPDM is often the most common choice, it’s important to understand that other roofing systems are also widely used, depending on building type, budget, and performance needs.
TPO (Thermoplastic Polyolefin) is another single-ply membrane that has seen increased use in recent years. It offers strong UV resistance and energy efficiency, making it popular in buildings with high cooling demands. However, it is still gaining ground and is less proven over long-term performance compared to EPDM.
PVC (Polyvinyl Chloride) roofing is used on buildings where chemical resistance is needed, such as restaurants or factories. PVC membranes are durable, resistant to fire and grease, and can last up to 30 years. However, they tend to be more expensive than EPDM or TPO.
Built-Up Roofing (BUR), also known as tar and gravel roofs, was once a standard in commercial roofing. This system involves layers of bitumen and reinforcing fabrics, creating a durable and waterproof surface. However, BUR is heavy and labour-intensive to install, which has led many contractors to favour lighter single-ply systems.
Modified Bitumen Roofing is another variation of asphalt roofing that offers added flexibility and strength. It is commonly used in areas where foot traffic on the roof is expected, but it also requires more maintenance and can be more expensive over time.
Metal Roofing is often used on commercial buildings with pitched roofs. Its lifespan can exceed 40 years and it offers excellent wind resistance. However, metal systems are less common on flat roofs and can be noisy or more difficult to repair when issues arise.
Choosing the Right Roof for Your Commercial Property
At Roofer Northampton, we know that there is no one-size-fits-all solution when it comes to commercial roofing. While EPDM may be the most common type, the right choice for your property will depend on factors like the size of your building, the slope of the roof, climate exposure, expected foot traffic, energy efficiency goals, and of course, budget.
For example, a warehouse with minimal roof traffic and basic insulation needs may benefit most from a standard EPDM installation. On the other hand, a food processing plant might require the chemical resistance and fire safety features of a PVC roof. Buildings located in areas with high solar exposure may lean toward TPO for its reflective qualities, which help reduce cooling costs.
Before making a final decision, it’s essential to conduct a full roof survey with a qualified contractor who understands both the structural and operational demands of your building. At Roofer Northampton, we provide expert consultation, detailed condition assessments, and tailored recommendations based on your specific roofing needs.
The Role of Regular Maintenance
Even the best roofing systems require routine inspections to perform well over time. An EPDM roof, for instance, should be inspected twice a year, especially before and after winter. These inspections help identify small tears, drainage problems, or sealant failures that could lead to bigger issues if left unattended. Scheduled maintenance not only extends the roof’s lifespan but also helps you comply with warranty conditions and insurance policies.
Relying on a trusted local roofer ensures consistency, familiarity with your building’s layout, and timely response to any problems that arise. Roofer Northampton offers bespoke maintenance plans that keep your commercial roofing system in optimal condition all year round.
Environmental Considerations and Sustainability
Sustainability is becoming a more important consideration for many businesses, and roofing plays a role in that effort. EPDM is often favoured for its recyclable qualities and minimal environmental impact during manufacturing. While not as energy-reflective as TPO or PVC, EPDM’s durability means less frequent replacements and reduced material waste over time.
For businesses focused on energy efficiency, reflective roof coatings can be added to EPDM membranes to increase their ability to deflect sunlight and reduce heat absorption. Green roofing options such as living roofs or solar panel integration can also be applied to certain membrane systems, offering long-term environmental and financial benefits.
Final Thoughts
When it comes to commercial roofing, EPDM has earned its place as the most common and trusted solution across a wide range of industries. Its durability, cost-effectiveness, and adaptability make it a smart choice for many property owners and facility managers. However, the best roofing system for your building should be selected based on careful assessment of your property’s needs, usage patterns, and long-term goals.
