When it comes to commercial premises, building requirements can differ greatly from domestic properties. And this includes the roofing. So, if you’re planning a commercial roofing project, it’s important to use the correct materials whilst taking into account the building size and any external fixtures and fittings.

To help you get better acquainted with the types of commercial roofing available, we’ve highlighted the key features of some of the most common commercial roofing options.

Read on to find out more…


Does the Shape of Your Commercial Roof Matter?


There’s only one answer to this question and it’s a resounding yes!

Quality commercial roofing should support both your building requirements and complement the style of architecture. 

For large, contemporary commercial buildings, flat roofing is a popular choice due to its cost-effectiveness, energy efficiency and easy maintenance. What’s more, the durability of flat roofing means that it can often withstand even the worst of weather conditions. 

If your commercial premises are housed within a period property with traditional building features and an existing pitched roof, then it’s best to stick with this style of roofing.

Converting a pitched roof to a flat roof can be costly, time-consuming and complex, particularly with listed buildings, as you will need to obtain consent in order to alter the character of the property. 

By replacing your existing pitched roof with a similar style, not only will you preserve the traditional aesthetic of the building but you’ll also benefit from the superior drainage and retention of space that can be lost when installing a flat roof. 


Popular Types of Commercial Roofing


Single Ply Commercial Roofing 

Single Ply sheeting is a flexible and durable commercial roofing solution that is most often used for flat or low-sloped roofs. It is made from a flexible synthetic polymer material which makes it hard-wearing and waterproof. 


PVC Single Ply Roofing 

The most popular type of single-ply roofing material is PVC (Poly Vinyl Chloride) which accounts for 80% of the market in the UK. Available in a variety of colour options, it is lightweight, great for corners and joints, and simple to install.

TPO Single Ply Roofing

Another example of a thermoplastic single-ply membrane is TPO, or Thermoplastic Polyolefin. This has very similar properties to PVC but is more environmentally friendly as it doesn’t contain plasticisers and can be partially recycled. One thing to note when using TPO is that it must be thoroughly cleaned before welding otherwise it may not bond efficiently.  

EPDM Single Ply Roofing

EPDM (Ethylene Propylene Diene Monomer) is more popular for domestic projects but can still be used for commercial roofing. It is elastic and cost-effective, however, it is only available in black and must be ballasted to ensure maximum fire resistance. 


Asphalt Shingles

Asphalt roof shingles are another popular roofing type more commonly found on domestic buildings, however, they can still work well for commercial use. Asphalt shingles are made from a blend of fibreglass or felt paper which are treated with a layer of asphalt before being coated with stone granules.

Because of the asphalt component, these roofing tabs offer a great level of waterproofing and are available in a number of colours and styles. 

Although a cheaper material in the short term, one of the downsides of using Asphalt shingles for commercial roofs is that they can require more repairs than other roof types. On average, you can expect to need a replacement after 15-20 years. 


Slate is an iconic roofing material that stands the test of time. When installed correctly and properly maintained, slate roof tiles can last up to 100 years!

With premium energy efficiency, optimal durability and a timeless aesthetic, slate is an excellent choice for homes and businesses in and around Bath. 

One thing to consider when investing in slate roofing is that it can be costlier than alternative roofing materials and requires expert installation. As the roofing tiles can be very fragile during the installation process, you need an experienced roofing specialist to carry out the job. 



Concrete commercial roofing is yet another option with excellent resilience and weather resistance. Although slightly more expensive than other roofing materials, it can be a worthwhile investment if you require something solid, reliable and low maintenance. 

When considering concrete roofing for your commercial project, it is important to note that your building must be structurally sound due to the weight of the material. If your concrete roof is not structurally supported, defects can occur and you run the risk of collapse. 


Green Roofing

As commercial businesses become more aware of their environmental impact, the need for more sustainable roofing options is increasing. 

This is where green roofing offers an excellent solution. 

Green roofing is roofing that can support the growth of plants and vegetation. When completely or partially covered in plants, your green roof can help to protect your building, produce oxygen, reduce energy consumption and provide sustainable drainage. 

So, what are the limitations?

When considering a green roof for your commercial building, it’s important to be aware that the installation can be more costly due to the additional load which requires greater support. 

Furthermore, you will need to maintain your new biosphere. Just like any garden, your green roof will need weeding, watering and fertilising to stay in tip-top condition!



Quality metal roofing can be costly, however, when properly installed, it can last from 50 to 75 years. 

A sturdy and safe option, metal standing seam roofing is perfect for commercial warehouse projects as it can handle the weight of heavy machinery and requires little maintenance.  

Another great benefit of metal roofing is that it is energy efficient. Metal roofs reflect harsh UV light rays that generate surface-level heat, allowing your staff to keep cool. 

If you’re considering a metal roof, you will need to keep up with regular inspections twice a year, to ensure that your roof is safe and secure.
