When discussing flat roofing, it’s easy to assume that newer materials such as EPDM rubber, GRP fibreglass, and single ply membranes have completely replaced traditional felt roofing. While these modern systems have certainly become popular, roof felting remains one of the most widely used and trusted flat roofing solutions throughout the UK.
The key is understanding that today’s felt roofing is very different from the felt roofs installed decades ago. Modern materials, improved manufacturing techniques, and professional installation methods have transformed felt into a durable, weather-resistant roofing system capable of protecting homes and commercial buildings for many years.
So, is traditional roof felting still worth considering in 2026?
For many property owners, the answer is yes.
At PW Flat Roofing, we install, repair, and replace felt roofing across Luton, Dunstable, Bedfordshire, Hertfordshire, and surrounding areas. In this guide, we’ll explain how roof felting works, how it has evolved, and why it continues to be a reliable choice for flat roofing projects.
What Is Roof Felting?
Roof felting is a waterproof roofing system designed primarily for flat and low-pitched roofs.
Rather than using a single waterproof sheet, felt roofing is built using several layers of reinforced bitumen membranes. Together, these layers create a strong barrier that protects the roof structure from rain, moisture, and everyday weather exposure.
Modern felt roofing systems are far more advanced than many homeowners realise. Today’s materials include reinforced polyester cores and modified bitumen, making them stronger, more flexible, and more resistant to cracking than earlier generations of roofing felt.
When installed correctly, roof felting offers dependable waterproof protection while remaining one of the most cost-effective flat roofing options available.
Is Today’s Felt the Same as Older Roofing Felt?
This is one of the biggest misconceptions surrounding felt roofing.
Older felt roofs installed many years ago often suffered from splitting, blistering, and premature wear because the materials available at the time were relatively basic.
Modern roof felting has benefited from decades of technological improvements.
Today’s systems feature:
- Stronger reinforcement materials
- Improved waterproof performance
- Better flexibility
- Increased UV resistance
- Longer expected lifespan
As a result, modern felt roofing performs far better than the traditional systems many people remember.
Where Is Roof Felting Commonly Used?
Roof felting remains an excellent solution for a wide variety of properties.
It is frequently installed on:
- Garages
- Home extensions
- Garden offices
- Porches
- Workshops
- Apartment buildings
- Commercial properties
- Storage buildings
Its versatility is one of the reasons it continues to be specified by roofing contractors across the UK.
Why Property Owners Still Choose Felt Roofing
Despite the availability of newer roofing materials, felt roofing continues to attract homeowners and businesses for several practical reasons.
Excellent Value for Money
One of the biggest advantages of felt roofing is affordability.
Compared with some alternative flat roofing systems, felt often provides excellent waterproof performance at a competitive installation cost.
For homeowners replacing an ageing garage roof or installing a new extension, this balance of quality and affordability is particularly appealing.
Reliable Waterproof Protection
Modern felt roofing uses multiple waterproof layers that work together to keep moisture out.
When installed by experienced roofing specialists, the finished roof provides dependable protection against heavy rainfall and the changing British weather.
Suitable for a Wide Range of Projects
Not every property requires the most expensive roofing system available.
Modern felt roofing performs well across many domestic and commercial applications, making it a flexible solution for different building types and budgets.
Straightforward Repairs
Although modern felt roofs are highly durable, occasional repairs may eventually become necessary.
One advantage of felt roofing is that localised damage can often be repaired without replacing the entire roof.
This can help reduce long-term maintenance costs while extending the roof’s overall lifespan.
How Long Does Roof Felting Last?
A common concern among homeowners is whether felt roofing lasts long enough to justify the investment.
The answer depends on several factors, including installation quality, maintenance, drainage, and weather exposure.
As a general guide, professionally installed modern felt roofing typically lasts:
15 to 25 years
Many systems continue performing beyond this timeframe when properly maintained.
Routine inspections, clean gutters, and prompt repairs all contribute to maximising roof lifespan.
How Does Felt Compare with Other Roofing Systems?
Every flat roofing material has its own strengths.
Rather than asking which system is universally better, it’s more useful to compare how each performs in different situations.
Felt vs EPDM Rubber
EPDM rubber roofing is known for its exceptional flexibility and long lifespan, often lasting up to 50 years.
Felt roofing generally offers a lower installation cost while still providing reliable weather protection.
For many residential projects, felt remains an excellent value option.
Felt vs GRP Fibreglass
GRP fibreglass creates a seamless, smooth finish that is particularly popular for visible roof areas.
Felt roofing provides similar waterproof protection while often representing a more affordable solution.
Felt vs Single Ply Membrane
Single ply membrane roofing is increasingly used on larger residential and commercial buildings due to its durability and modern appearance.
Felt roofing continues to compete well where affordability, versatility, and proven performance are priorities.
Is Felt Roofing Environmentally Friendly?
Modern roofing manufacturers have also made progress in improving sustainability.
Many felt roofing systems now offer improved durability, meaning roofs require replacement less frequently.
Longer-lasting roofing materials help reduce waste over the building’s lifetime.
In addition, replacing an ageing roof often provides an opportunity to improve insulation, reducing heat loss and improving overall energy efficiency.
How to Get the Best Performance from a Felt Roof
Even the best roofing material requires proper installation and basic maintenance.
To maximise the lifespan of a felt roof:
- Choose experienced roofing professionals.
- Ensure the roof has adequate drainage.
- Keep gutters and outlets free from debris.
- Arrange periodic roof inspections.
- Repair minor damage promptly.
These simple measures can significantly extend the roof’s service life.
Common Myths About Roof Felting
Some misconceptions continue to discourage homeowners from considering felt roofing.
One common myth is that felt roofs always leak.
In reality, leaks are far more likely to result from poor installation or neglected maintenance than the roofing material itself.
Another misconception is that felt roofs only last ten years.
Modern reinforced felt systems often provide well over two decades of reliable performance when professionally installed.
Finally, some people assume felt is outdated.
While newer materials continue to gain popularity, felt roofing remains widely used because it consistently delivers reliable performance and excellent value.
Why Professional Installation Matters
Regardless of the roofing material chosen, installation quality plays a major role in long-term performance.
Proper preparation, waterproof detailing, secure joints, correct drainage, and quality workmanship all contribute to how well the roof performs over time.
