Why Choose EPDM Rubber?
Long-lasting Performance
EPDM rubber roofing is built for longevity and holds up well in UK weather, making it a strong choice for long-term protection.
Seamless waterproof finish
Installed as a single membrane where possible, EPDM reduces weak points and helps prevent leaks caused by failed joints.
Low maintenance
EPDM resists cracking and splitting seen with older felt systems, and typically needs very little upkeep once installed.
Ideal for garages & extensions
A neat, modern finish that suits common domestic flat roofs, including garages, bay roofs, dormers and extensions.

Why We Use EPDM Rubber
Choosing the right flat roofing system is essential for long-term protection and peace of mind. That’s why we specialise exclusively in EPDM flat roof replacements rather than short-term repairs to older felt systems.
EPDM is a modern rubber roofing membrane designed to withstand the UK climate, offering excellent durability, flexibility and resistance to cracking or splitting over time. When installed correctly, it provides a clean, reliable waterproof finish with minimal ongoing maintenance.
By focusing solely on EPDM installations, we’re able to deliver consistent quality, proven performance and honest advice on whether a flat roof replacement is the right solution for your property.

Why EPDM?
EPDM offers a far longer lifespan than traditional felt flat roofing and is installed as a single membrane where possible, reducing weak points and the risk of leaks. It remains flexible in cold weather and performs well year-round, making it a reliable long-term solution.
Why We Don’t Repair Felt Roofs
Rather than offering temporary repairs, we specialise in felt to EPDM flat roof replacements, providing a modern, long-lasting solution that eliminates weak points and ongoing maintenance issues. By replacing failing felt roofs with EPDM, we’re able to deliver a clean, reliable waterproof finish with proven long-term performance.

Frequently asked questions
Replacing a flat roof is a significant investment, and it’s natural to have questions before deciding how to proceed.
Below you’ll find answers to some of the most common questions we’re asked about EPDM flat roof replacements, including suitability, timescales, guarantees and what to expect during the process.
How long does an EPDM flat roof replacement take?
Most EPDM flat roof replacements are completed within one to three days, depending on the size of the roof, access requirements and weather conditions. We’ll always confirm a clear timescale before work begins.
Do you repair felt flat roofs?
We don’t carry out felt flat roof repairs. In our experience, repairs to older felt systems are often short-term solutions. Instead, we specialise in replacing failed felt roofs with modern EPDM systems designed for long-term performance.
Is EPDM better than traditional felt roofing?
EPDM offers a significantly longer lifespan than traditional felt and is installed as a single membrane where possible, reducing weak points and the risk of leaks. It also remains flexible in cold weather and requires minimal maintenance.
Will scaffolding be required for a flat roof replacement?
Scaffolding isn’t always required for flat roof replacements, particularly for garages and single-storey extensions. Where access or safety requires it, we’ll advise you in advance as part of your survey.
How do I know if my flat roof needs replacing rather than repairing?
We don’t carry out temporary repairs to older felt flat roofs, as these systems are often near the end of their lifespan and prone to recurring leaks.
Instead, we specialise in felt to EPDM flat roof replacements, removing the failing felt system and installing a modern EPDM membrane designed for long-term waterproof protection. This approach eliminates weak points and provides a far more reliable, low-maintenance solution for homeowners.
Are EPDM flat roofs guaranteed?
Yes. All EPDM flat roof replacements are installed to a high professional standard and backed by clear workmanship guarantees, giving you peace of mind once the work is complete.
What types of flat roofs can you replace with EPDM?
We install EPDM flat roofing on a wide range of domestic flat roofs, including garages, extensions, bay roofs and dormer roofs.
Do you provide free flat roof surveys and quotes?
Yes. We offer free, no-obligation flat roof surveys and clear quotations, along with honest advice to help you decide whether an EPDM replacement is right for your property.
