Are you considering a new flat roof? They’re a popular choice for both commercial and domestic projects, from porches and garages to dormer windows and home extensions.
However, before you decide to install a flat roof system, it’s essential to weigh up the pros and cons, and the best modern materials to use.

Here’s everything you need to know.

Is it a good idea to have a flat roof?

Flat roofs can be a great solution for many projects, but it’s important to consider your property needs, budget and what you want to achieve. Flat roofs tend to be more cost-effective to install and maintain compared to pitched roofs, requiring fewer materials and labour, making them an attractive option for many households and businesses.

Maintenance is often simpler due to the accessibility of flat roofs, with contractors reaching the entire surface to perform efficient inspections and repairs. Some modern flat roofs even provide additional usable space, which can be transformed into a rooftop garden or solar panel installation.

However, you must use a reputable roofing company, as proper drainage is crucial for flat roof installations. Inadequate drainage can lead to water pooling, leaks and structural issues.

What are the pros and cons of flat roofing?

Depending on where they’re installed, flat roofs have a sleek and modern look that complements contemporary architectural designs. They can also be used as functional spaces, providing additional value to your property.

Regular upkeep is crucial to prevent issues like leaks, ponding and membrane damage, and you’ll need to carefully consider the material you want to ensure the cost-effective benefits aren’t outweighed by maintenance needs.

What’s the best value flat roof system?

When considering flat roofing systems, choose a material offering the best value for your specific needs. Popular options include EPDM, GRP and felt flat roofs, depending on your budget and aims for the roof.

If leaks have become a costly problem you want to avoid, selecting a high-quality material that lasts for decades, like GRP fibreglass or EPDM rubber, can offer better long-term solutions. GRP fibreglass is also perfect for high-traffic areas. However, if you’re looking for a more affordable option for replacing old flat roofing, bitumen felt should be considered.

When should you replace your flat roof?

Knowing when to replace your flat roof will help prevent costly damage and ensure your property remains watertight.

If you have frequent leaks that repairs can’t fix, it may be time for a replacement. Water ingress is often caused by damaged membranes, blisters or cracks that compromise the roof’s integrity. You may have also spotted pooling on your flat roof, indicating rainwater isn’t draining properly.

If your roof looks worn with visible damage, it’s time to consider a replacement.
