Whether you are replacing an ageing flat roof or starting a new build, this guide will help you understand your options and choose a roofing system that protects your investment for years to come.
Key Factors to Consider When Choosing a Commercial Roof
Choosing the right roofing system for a commercial property is not just about picking the cheapest option or going with what looks good. The best roofing system for your business will depend on a mix of practical and financial considerations, along with the unique demands of your building.
Before you make a decision, take time to think through the following factors:
- Budget: Start with what you can realistically spend. Keep in mind that the cheapest option upfront is not always the most cost-effective in the long run. Some systems last longer or require less maintenance, which can save you money over time.
- Roof design and structure: Is your roof flat, pitched or somewhere in between? Certain systems are better suited to flat roofs, while others are ideal for sloped or curved surfaces. The shape and structure of your building will often guide your options.
- Energy efficiency: A well-insulated roofing system can help lower heating and cooling bills. Some systems offer reflective surfaces or work well with solar panel installations, which can improve your energy performance and reduce long-term costs.
- Durability and weather resistance: In the UK, your roof needs to withstand wind, rain, frost and, occasionally, extreme heat. Choose a system that is built to handle our changing weather without constant repairs.
- Maintenance requirements: All roofs need upkeep, but some require more attention than others. If you want to minimise long-term maintenance costs, choose a system known for low upkeep and easy access for inspections.
- Usage: Will the roof be used to support equipment, foot traffic or green space? Some systems are better equipped for heavy use or added weight, so make sure the system you choose can handle how the roof will be used day to day.
By considering these factors early in the planning process, you can avoid costly surprises and make sure your investment adds real value to your property. In the next sections, we will take a closer look at some of the most popular commercial roofing systems available across the UK in 2025.
1. Single-Ply Membrane Roofing (EPDM, TPO, PVC)
Single-ply membrane roofing is one of the most popular choices for commercial buildings in the UK, especially those with flat or low-slope roofs. It is lightweight, cost-effective and quick to install, which makes it a great option for businesses that need minimal disruption during construction or refurbishment.
There are three main types of single-ply membranes commonly used:
- EPDM (Ethylene Propylene Diene Monomer): A rubber-based system known for its flexibility, durability and weather resistance. It performs well in cold UK climates and can last over 25 years when installed correctly.
- TPO (Thermoplastic Polyolefin): A more recent option that reflects heat, making it an energy-efficient choice. TPO is also resistant to UV, algae and chemical exposure, which is ideal for roofs exposed to external elements.
- PVC (Polyvinyl Chloride): Commonly used in areas with higher foot traffic. It is tough, fire-resistant and known for its long-term performance in a wide range of conditions.
One of the biggest advantages of single-ply systems is their waterproofing performance. Because the material is installed in large sheets with heat-welded seams, it creates a seamless barrier that protects the building from leaks. It also requires less structural support than heavier roofing systems, which can reduce installation time and costs.
These systems are also compatible with green technologies, such as rooftop solar panels and rainwater harvesting systems, making them a smart choice for environmentally conscious businesses looking to reduce their carbon footprint.
If your commercial property has a flat roof and you want a low-maintenance, long-lasting solution, single-ply membrane roofing is definitely worth considering.
2. Built-Up Roofing (BUR) Systems
Built-up roofing, often referred to as BUR, is one of the oldest and most reliable commercial roofing systems still in use today. It has been a go-to solution for flat and low-slope roofs for decades, and it continues to be a solid choice for UK businesses that prioritise durability and weather protection.
BUR systems are made up of multiple layers of bitumen (asphalt) alternated with reinforcing fabrics, typically topped off with a layer of gravel or a reflective coating. These layers work together to create a waterproof and weather-resistant surface that can handle heavy foot traffic, standing water and even harsh weather over long periods of time.
One of the key strengths of a BUR system is its thickness and strength. The multi-layer construction provides excellent protection against water ingress and physical damage, making it a great choice for buildings where the roof may be used for equipment or occasional access.
BUR roofs also offer good insulation properties and can help regulate temperature inside the building, especially when paired with additional insulation layers. This can be a plus for reducing heating and cooling costs throughout the year.
On the downside, installation can take longer compared to single-ply systems, and the process involves hot materials, which may not be suitable for all sites. However, once installed, a BUR system is built to last — many last between 20 and 30 years with proper maintenance.
For business owners who want a rugged, proven system that performs reliably in a range of conditions, built-up roofing remains a dependable option.
3. Metal Roofing Systems
Metal roofing is a popular choice for commercial buildings across the UK, particularly for those with pitched or slightly sloped roofs. It combines excellent durability with a sleek, modern appearance and is often chosen for warehouses, industrial buildings, retail units and even offices that want a professional finish with long-term value.
Materials used in metal roofing include steel, aluminium and zinc, each offering slightly different strengths. Most metal systems are installed in large panels or sheets, which are fastened and sealed to provide a tough, weather-resistant surface that performs well in all seasons.
One of the biggest advantages of a metal roof is its lifespan. With proper installation and maintenance, metal roofing can last 40 to 60 years or more. It is also highly resistant to fire, pests and mildew, which means fewer problems and lower repair costs over time.
In addition to being durable, metal roofs are known for their energy efficiency. Many systems have reflective coatings that help reduce heat absorption, keeping the building cooler in summer. This can make a noticeable difference in energy bills, especially when combined with modern insulation and ventilation.
Like any roofing system, metal requires maintenance to stay in good shape. Regular inspections, gutter cleaning and sealing any small gaps or corrosion spots can go a long way in extending the life of the roof.

If your commercial property needs a long-lasting, low-maintenance roof with strong weather performance and a modern look, metal roofing is a very smart choice.
4. Green Roofs (Sedum Roofs)
Green roofs, also known as sedum roofs or living roofs, have gained a lot of popularity in recent years — and it is easy to see why. These systems involve adding a layer of vegetation over a waterproof membrane, turning an ordinary roof into a functional green space. For UK businesses that want to boost their environmental credentials, improve insulation and even create usable outdoor areas, green roofs are a fantastic option.
There are two main types of green roofing systems:
- Extensive green roofs: These are lightweight and low-maintenance, typically using hardy plants like sedum. They are ideal for buildings that need the eco-benefits without the need for ongoing gardening or regular access.
- Intensive green roofs: These systems can support a wide range of plants, including grass, shrubs and small trees. They are heavier and require more care, but can be designed as full rooftop gardens or social spaces for staff and visitors.
Green roofs offer several key benefits. They provide natural insulation, helping to reduce heating and cooling costs. They also absorb rainwater, which helps with drainage and reduces pressure on local water systems — particularly useful in cities and built-up areas. On top of that, they can improve air quality, increase biodiversity and even extend the life of the roof membrane by protecting it from UV rays and temperature extremes.
While the upfront cost is higher than some other systems, many businesses see this as a long-term investment. It is especially appealing for environmentally conscious brands or organisations applying for sustainability certifications.
If your commercial building is structurally suitable and you want to combine function with sustainability, a green roof could be a great addition that offers both performance and positive brand impact.
5. Liquid-Applied Roofing Systems
Liquid-applied roofing systems have become a popular solution for both new installations and refurbishments, especially on flat and irregularly shaped commercial roofs. These systems are applied cold as a liquid, which then cures to form a seamless, waterproof membrane over the existing roof structure.
One of the main advantages of liquid roofing is its versatility. It can be applied to a wide range of surfaces, including metal, concrete, felt and asphalt. This makes it particularly useful for older roofs that need upgrading without the cost and disruption of a full replacement.
Because there are no seams or joints, liquid systems offer excellent waterproofing and are less prone to leaks. They are also ideal for detailing around awkward shapes, upstands, skylights and ventilation units — areas where other roofing systems might struggle to provide full coverage.
Another big benefit is speed. Since the system can be applied directly to an existing roof, installation is often faster and less disruptive, which is a major plus for businesses that need to stay open during the work. Many products are designed to cure quickly, even in damp UK conditions, allowing for year-round application.
Liquid-applied systems can also be part of a larger energy efficiency upgrade, especially when paired with added insulation. Some systems offer reflective coatings that help reduce heat absorption, supporting better temperature control inside the building.
If you are working with an older roof or need a fast, flexible solution with minimal disruption, liquid-applied roofing is well worth considering.
Cost Considerations for Commercial Roofing
When planning a new roof for a commercial building, cost is always one of the biggest concerns. But it is important to look beyond just the upfront price. A roofing system that costs more initially may offer better long-term value by lasting longer, reducing energy bills or lowering maintenance needs over time.
Here is a general breakdown of what to consider when budgeting for a commercial roofing project:
- Installation costs: This includes materials, labour, access equipment and any necessary removal of old roofing. Simpler systems like single-ply membranes tend to be quicker and cheaper to install, while more complex builds like green roofs or BUR systems take more time and resources.
- Roof size and shape: Larger roofs and those with unusual layouts or lots of detailing will naturally cost more to install and maintain.
- Lifespan and performance: A metal roof might cost more than a felt one, but if it lasts twice as long with fewer repairs, it could be the better investment. Always weigh the cost against the expected service life and performance benefits.
- Maintenance and repair: Consider how much it will cost to keep the roof in good condition. Some systems require frequent checks, resealing or cleaning, while others are much lower maintenance.
You should also think about the wider picture. A new roof might be part of a larger refurbishment project that includes guttering, painting or insulation work. To get a sense of average property upkeep costs, take a look at our guide on Average Costs of Exterior Painting and Repairs.
Ultimately, the right roofing system is one that fits your building, your budget and your long-term goals. Always get detailed quotes from experienced roofing professionals and make sure they include options for materials, warranties and projected maintenance needs.
Energy Efficiency and Insulation Benefits
Energy efficiency is no longer just a nice bonus — it is becoming a priority for businesses looking to reduce operating costs and meet environmental targets. Your roof plays a big role in how well your commercial building retains heat in winter and stays cool in summer, especially in the UK where weather conditions can vary widely throughout the year.
Modern roofing systems are designed with insulation and energy performance in mind. Many options, such as single-ply membranes and metal roofs with reflective coatings, help reduce heat absorption during warmer months. At the same time, green roofs and systems with added insulation layers can help retain warmth, cutting down on the need for constant heating.
These savings add up over time. Lower heating and cooling bills not only reduce strain on your budget, but also make your building more comfortable for employees, tenants or customers. Some roofing systems are also compatible with solar panels or heat pumps, making it easier to integrate other energy-saving technologies down the line.
If you are planning a full upgrade, it might also be worth reviewing your heating system at the same time. A well-insulated roof works best when paired with an efficient heating setup. You can learn more in our guide to Choosing the Right Heating System for Your Home, which also applies to business premises.
Choosing a roofing system that supports energy efficiency is not just a short-term win — it is an investment in your building’s performance, environmental impact and long-term operating costs.
Maintenance and Longevity
No matter how high-quality or well-installed your commercial roofing system is, regular maintenance is key to making it last. A proactive approach can help you spot small issues before they turn into costly repairs and will keep your roof performing at its best for years to come.
Different roofing systems come with different maintenance needs. For example, metal roofs may require checks for rust and resealing at joints, while green roofs need basic upkeep like weeding, drainage checks and occasional replanting. Single-ply membranes should be inspected for punctures or lifting seams, especially after storms or heavy winds.
At a minimum, your commercial roof should be inspected at least once a year, along with checks after any severe weather. Routine maintenance should include clearing debris from drains and gutters, checking flashing and seals, and inspecting the surface for cracks, splits or signs of wear.
We have put together a detailed guide on how to stay on top of this with practical, seasonal advice. Have a look at our article on Expert Tips on Maintaining Your Roof and Gutters to keep your building in great condition all year round.
Longevity depends not just on the type of system you choose, but how well you look after it. A well-maintained roof can easily exceed its expected lifespan, while neglected systems often fail much sooner than necessary. Keeping up with inspections and minor repairs protects your investment and helps avoid expensive surprises later on.
