Thinking about installing an EPDM flat roof but unsure what it might cost? Unlike standard roofing options, EPDM pricing isn’t fixed—it depends on several factors, including your roof’s size, condition, and the quality of materials used. While we can’t give a one-size-fits-all price, understanding what influences cost can help you budget wisely and make a confident decision.
Naturally, larger roofs require more material and labour. Complex layouts with multiple edges, dormers, or parapets can increase installation time and cost.
Older roofs or those with damage may need additional preparation, such as removing old membranes or repairing the substrate. EPDM performs best when applied to a smooth, sound surface, so prep work is a key factor in total cost.
EPDM membranes come in different thicknesses and qualities. Thicker membranes provide better durability and longer lifespans but can slightly increase costs.
Adding insulation beneath an EPDM membrane can improve energy efficiency and comfort, but it will also add to the overall cost. The long-term benefits often outweigh the initial investment.
A professional, certified installer ensures the roof is watertight and long-lasting. Choosing experienced installers may cost more upfront but prevents expensive repairs down the line.
When planning a new EPDM (rubber) flat roof, it’s natural to ask what kind of budget you’ll need. While costs vary depending on roof size, condition, and the complexity of the job, most domestic projects fall within a fairly predictable range.
For reference, a typical EPDM flat roof installation in the UK may cost:
| Type of Job | Estimated Cost (Including Materials & Labour) |
|---|---|
| Small domestic roof (e.g. single garage) | £1,500 – £2,500 |
| Medium roof (e.g. extension or porch) | £2,500 – £4,000 |
| Large or double garage roof | £4,000 – £6,500+ |
| Per square metre (average) | £70 – £90 |
Estimated cost: £1,500 – £2,500
Estimated cost: £2,500 – £4,000
Estimated cost: £4,000 – £6,500+
Estimated cost: £70 – £90 per m²
These are guide figures only and can shift depending on your property, insulation needs, and roof preparation work.
It’s also worth noting that labour usually accounts for around half of the total cost, as proper EPDM installation requires expertise to ensure a watertight, durable finish.
While an EPDM roof may cost slightly more than basic felt, it’s an investment in long-term performance. A correctly installed system can last 30 years or more, providing excellent weather protection and minimal maintenance — which means fewer repair bills over time.

While the initial investment may seem higher than cheaper alternatives, EPDM roofs can last 30–50 years with minimal maintenance. This longevity, combined with low upkeep costs and resistance to harsh weather, often makes EPDM a cost-effective choice over the life of the roof.
When budgeting for an EPDM roof, consider the following factors:
When planning your EPDM rubber roof installation, it’s worth understanding what drives the overall price. Every project is different, so while a cost guide can give you an idea, your final cost estimate will depend on a few key factors.
The size and shape of your roof play the biggest role — larger, more complex areas require more materials and time to complete. Access also matters; roofs that are difficult to reach or require extra scaffolding can increase professional costs.
The type of insulation, edge trims, and drainage setup you choose will also influence your rubber roof cost. A straightforward replacement may be quicker and cheaper, while a full EPDM roof installation with new boarding and insulation will require more work but deliver superior performance and efficiency.
Beyond the initial price, EPDM rubber roofing offers some of the best long-term value on the market. Its low maintenance costs, exceptional durability, and resistance to UV and frost mean you spend less over time compared to other materials. Plus, it’s an environmentally friendly choice — EPDM is fully recyclable and helps improve thermal efficiency, reducing your property’s carbon footprint.
In short, while every roof is unique, investing in a quality rubber roof installation by experienced professionals ensures long-lasting protection and peace of mind.
This Chelmsford project was more than just a new roof—it was a much-needed fix after years of problems. The client had previously endured a poorly installed roof over her living space, with no insulation between the joists and repeated leak repairs. After several harsh winters, the roof’s weaknesses became increasingly apparent, prompting her to seek a long-term, reliable solution.
We removed the failed roof system, installed full insulation to improve thermal performance, and fitted a Firestone EPDM flat roof engineered for durability and excellent weather resistance. The new roof provides superior protection against frost, heavy rain, and fluctuating temperatures, ensuring the property remains warm, dry, and secure throughout winter. In addition, we built a fully boarded, neatly trimmed porch roof, finished with matching EPDM membrane for a clean, modern appearance that complements the home.
This recent project in Hitchin involved the installation of a high-performance EPDM flat roof system, providing long-lasting protection and a clean, modern finish. The client wanted a durable, low-maintenance solution for their rear extension—and we delivered just that with expertly laid Firestone EPDM and precision detailing throughout.
We handled every part of the job, from stripping off the old roof to professionally fitting the new single-ply membrane with neat, watertight edges and custom trim work. As always, our team prioritised both quality and appearance—resulting in a roof that not only performs in all weather but also looks sharp and built to last.
The homeowner was delighted with our work and left us a glowing 5-STAR REVIEW!
