Felt roofing remains one of the most popular and practical choices for flat roofs, sheds, garages, and extensions. It’s affordable, effective, and easy to maintain when installed correctly. However, over time, felt roofs naturally deteriorate due to exposure to the elements. Knowing when to replace your felt roof is crucial for maintaining proper protection and preventing further issues. At Clifton Roofing Repairs, we help homeowners across Clifton, Nottingham identify the right time for replacement to ensure lasting performance and safety.
Understanding Felt Roofing
Felt roofing is made up of bitumen layers, reinforced with fibreglass or polyester and topped with a protective mineral surface. Its layered design provides excellent waterproofing and resilience, but like all materials, it has a finite lifespan. Constant exposure to UV rays, rain, frost, and fluctuating temperatures gradually wears it down, which can compromise the roof’s effectiveness.
Signs It’s Time to Replace Your Felt Roof
1. Visible Cracking and Blistering
One of the earliest signs of felt deterioration is the appearance of cracks or blisters on the surface. These form when moisture becomes trapped beneath the felt, causing it to expand under heat. Once this happens, the roof can no longer maintain its waterproof seal.
2. Persistent Leaks or Damp Patches
If you notice water ingress, damp stains, or mould on ceilings or walls beneath a felt roof, it’s likely that the waterproof membrane has failed. Even small leaks can escalate quickly, leading to significant structural problems if left unaddressed.
3. Lifting or Peeling Edges
Over time, the adhesive bond that keeps felt attached to the roof deck may weaken. This can cause the edges to curl, lift, or peel away. Once gaps form, water can easily penetrate underneath, accelerating damage.
4. Sagging or Uneven Areas
A sagging appearance often indicates that water has been pooling on the roof surface. Flat roofs must have proper drainage, and a sagging felt roof suggests that the substrate beneath is weakening due to moisture exposure.
5. Age of the Roof
Even if no obvious damage is visible, an ageing felt roof—typically more than 10–15 years old—should be inspected by a professional. Over time, the material loses flexibility and weather resistance, making it more susceptible to cracking and leaks.
Why Timely Replacement Matters
Delaying felt roof replacement can lead to far greater issues later on. The longer damaged felt remains in place, the more likely water will seep into the roof structure, leading to rot or insulation damage. Replacing the felt before major problems arise ensures your property stays protected and extends the lifespan of the underlying materials.
At Clifton Roofing Repairs, we recommend routine inspections, especially after extreme weather, to catch problems early. A timely replacement not only prevents damage but also improves the overall energy efficiency and appearance of your property.
Modern Felt Roofing Offers Improved Performance
Advancements in roofing materials mean modern felt systems are far more durable than older varieties. They often incorporate improved UV protection, enhanced flexibility, and multiple layers for added strength. When installed by experienced roofers, these systems deliver long-term waterproofing and require minimal maintenance.
The Benefits of Replacing an Old Felt Roof
Upgrading your felt roof offers several key advantages:
- Better waterproofing – prevents leaks and moisture intrusion.
- Improved appearance – gives your roof a clean, new look.
- Enhanced durability – withstands temperature fluctuations and harsh weather.
- Peace of mind – ensures the property is fully protected for years to come.
