Felt roofing has long been a trusted solution for flat roofs across the UK, offering excellent weather protection and a smooth, practical finish. Over time, however, even the most durable felt systems begin to show signs of wear and ageing. When that happens, property owners often face an important question — should you upgrade the existing felt roof or replace it entirely?
For homeowners and businesses in Burnham, Buckinghamshire, LS Roofing Burnham provides expert advice and professional installation for all types of felt roofing. Understanding when to upgrade and when to replace can help you make the most cost-effective decision for the long-term protection of your property.
Understanding the Lifespan of Felt Roofing
Traditional felt roofing systems are known for their resilience, but like all materials, they degrade with time. Factors such as UV exposure, temperature fluctuations, and general wear can cause the felt surface to crack, blister, or lift at the edges.
A typical felt roof can last anywhere from 10 to 20 years, depending on the quality of materials and installation. Regular maintenance can extend this lifespan, but once deterioration sets in, a decision needs to be made: is upgrading sufficient, or does a full replacement offer better value?
The Case for Upgrading Your Felt Roof
Upgrading is often a practical choice when the existing structure is still sound. It involves adding new layers or reinforcing sections of the roof to extend its performance and improve weather resistance without completely removing the old system.
Benefits of Upgrading
- Less disruption – Since the existing base remains in place, work can often be completed more quickly and with minimal impact.
- Enhanced durability – Adding modern waterproof membranes or overlay systems can significantly improve protection against leaks.
- Improved energy performance – Some upgrades include insulation enhancements that reduce heat loss.
- Environmentally conscious – Overlay systems can reduce waste by reusing parts of the existing roof rather than disposing of old materials.
When Upgrading Works Best
An upgrade from LS Roofing Burnham is typically suitable when:
- The roof deck and structure are in good condition.
- There are no widespread leaks or water damage beneath the surface.
- The felt surface has minor cracks, blisters, or ageing signs, but remains largely intact.
In such cases, an upgrade offers a cost-effective way to rejuvenate your roof without a full replacement.
When Replacement Is the Smarter Option
A full replacement becomes necessary when the existing felt system has reached the end of its serviceable life. Prolonged exposure to the elements, poor drainage, or underlying structural damage can make upgrading impractical or short-lived.
Signs That a Replacement Is Needed
- Persistent leaks or visible water ingress.
- Noticeable sagging or soft spots in the roof deck.
- Extensive cracking, lifting, or bubbling of the felt.
- Dampness inside the property linked to roof failure.
- Multiple repairs made over the years with limited improvement.
In these circumstances, replacing the roof entirely ensures long-term stability and prevents recurring issues.
Advantages of Full Replacement
- A fresh start – A new installation eliminates old material weaknesses, ensuring a watertight and reliable surface.
- Modern materials – Today’s felt systems include advanced polymers and bitumen that offer superior flexibility and longevity.
- Opportunity for improvement – Replacement allows for added insulation, improved drainage, and a cleaner appearance.
- Long-term protection – A professionally installed new felt roof by LS Roofing Burnham offers years of dependable performance.
Comparing Upgrade vs Replacement
When deciding whether to upgrade or replace, it’s important to weigh several key factors.
| Consideration | Upgrade | Replacement |
| Condition of existing roof | Good structure with minor wear | Significant damage or leaks |
| Disruption | Minimal | Moderate |
| Longevity | Extends lifespan by several years | Provides a completely new lifespan |
| Environmental impact | Reuses materials | Generates more waste |
| Best for | Roofs with minor defects or surface wear | Roofs with major water or structural damage |
A detailed inspection by LS Roofing Burnham can determine which option offers the best value for your specific property.
