Felt roofing remains one of the most popular flat roofing options in the UK due to its affordability, durability, and ease of installation. It’s commonly found on garages, extensions, garden buildings, and commercial properties, offering a strong, watertight surface that can perform well for many years when properly maintained. At Bognor Regis Roofing Repairs, we frequently work on felt roofs across Bognor Regis and West Sussex, helping homeowners and businesses extend the life of their roofs through expert repairs and maintenance.
Understanding Felt Roofing
Felt roofing consists of bituminous sheets that are layered and sealed together to create a waterproof barrier. Modern systems often use torch-on felt or self-adhesive materials, both designed for long-lasting protection against the unpredictable British weather.
When installed correctly and maintained regularly, felt roofing can provide a lifespan of 15–25 years, depending on the material quality and environmental conditions. However, like any roofing system, its longevity depends heavily on regular inspections and prompt attention to any damage.
The Lifespan of a Felt Roof
Several factors determine how long a felt roof will last, including the quality of the materials used, the skill of the installer, and the level of ongoing maintenance.
Key Factors Affecting Durability:
- Installation quality: Poor workmanship can lead to early failure due to poor adhesion, weak seams, or trapped moisture.
- Weather exposure: Constant UV radiation, rain, and frost can gradually cause the felt to dry out or crack.
- Foot traffic: Regular walking or placing heavy objects on the roof can wear away the surface coating and compromise the layers beneath.
- Drainage design: Flat roofs that don’t drain water efficiently are more prone to ponding, which accelerates deterioration.
Regular inspections, especially after severe weather, help to identify early signs of wear and tear, extending the roof’s lifespan considerably.
Common Felt Roofing Problems
While felt roofs are robust, they are not immune to damage. At Bognor Regis Roofing Repairs, we often find similar issues across properties in Bognor Regis and surrounding areas.
1. Blistering and Bubbling
Trapped moisture or air beneath the surface layer can cause blisters or bubbles to form. These weak points can burst over time, allowing water to penetrate the roof structure.
2. Cracking and Splitting
Over time, exposure to sun and temperature changes causes the felt to dry and become brittle. This can lead to cracks that compromise the waterproof seal.
3. Ponding Water
Flat roofs should have a slight fall to direct water towards drainage outlets. When this is missing or obstructed, water collects in pools, placing pressure on the felt and seams, leading to leaks.
4. Lifted Seams or Edges
Poor adhesion or weather damage can cause the edges of the felt to lift, creating openings for wind and water to enter. Once moisture gets underneath, the problem can quickly spread.
5. Moss and Algae Growth
Organic growth retains moisture and makes the roof surface slippery, increasing the likelihood of deterioration. Keeping the roof clean prevents long-term decay.
Maintaining a Felt Roof for Long-Term Performance
Regular maintenance is the key to extending the lifespan of a felt roof and avoiding costly repairs. Preventative care ensures the roof remains watertight and structurally sound throughout the year.
Maintenance Tips:
- Inspect regularly: Check for cracks, blisters, or loose edges every few months.
- Clear debris: Remove leaves, branches, and dirt that can trap moisture or block drainage.
- Check for ponding: After rainfall, ensure water isn’t collecting on the surface.
- Maintain gutters and outlets: Clean gutters and downpipes to ensure proper drainage.
- Repair minor damage promptly: Small cracks or lifted seams should be sealed immediately before they worsen.
By scheduling professional inspections through Bognor Regis Roofing Repairs, homeowners can catch early signs of deterioration before they lead to leaks or structural issues.
Advantages of Felt Roofing
Despite newer roofing materials available, felt continues to be a reliable and practical option for many properties in Bognor Regis.
Benefits Include:
- Cost-effective: Provides strong waterproof protection at a reasonable investment.
- Ease of repair: Damaged areas can often be patched or resealed without replacing the entire roof.
- Versatile use: Suitable for garages, sheds, porches, and commercial units.
- Improved modern performance: Torch-on felt systems are now more durable and UV-resistant than older types.
