TessCon recently completed an extensive roof felt replacement and chimney repair project on Farrier Road in Great Barr, Birmingham.
The property was suffering from deteriorated felt beneath the roof tiles, causing water ingress and damage to the underlying battens. Left untreated, issues like this can lead to rotten timber, leaks, and costly structural repairs.
Identifying the Problem: Rotten or Perished Roof Felt
Rotten or perished roof felt is a serious issue that compromises the integrity of any roof.
In this case, the bottom metre of felt, along with several other sections, had become brittle and torn over time.
The damage allowed rainwater to penetrate the roofline, running behind the fascia and potentially damaging structural timbers. A thorough inspection confirmed that the existing felt had reached the end of its service life and required replacement rather than temporary patching.
Professional Roof Felt Replacement Process
Once scaffolding was safely erected, our experienced roofers carefully stripped back the damaged tiles, removed the old battens, and disposed of the deteriorated felt.
We then installed a modern breathable membrane to provide long-lasting weather protection and prevent condensation build-up beneath the tiles.
New treated timber battens were fitted to support the roof structure and ensure durability against future moisture exposure.
- Removed damaged tiles, battens, and felt across the affected roof area.
- Installed new breathable roofing felt membrane for improved weather resistance.
- Replaced all battens with high-quality treated timber.
- Supplied and managed scaffolding to maintain a safe working environment.
Addressing Previous Poor Repairs
During inspection, our team discovered that flash band tape had been used between the adjoining properties as a makeshift joint.
This is a temporary fix that can quickly fail, allowing water to penetrate between homes.
We removed the flash band and installed a bonding gutter system, creating a durable, watertight connection that allows proper rainwater drainage and long-term protection.
Chimney Repointing and Lead Flashing Repairs
As part of the works, the chimney was also repointed and the surrounding lead flashings corrected. These are critical elements for maintaining a watertight seal between the chimney stack and roof surface.
The repaired flashing now provides a proper barrier against water ingress, preventing leaks around the chimney area.
Key Considerations for Rotten Roof Felt
Rotten or perished felt can cause significant roof problems if left untreated. Here are some important points homeowners should be aware of:
- Signs of trouble: Felt appears brittle, torn, or hanging down inside the loft, particularly near the eaves.
- Immediate risks: Water running behind fascias can lead to timber decay and internal dampness.
- Repair options: Minor tears may be patched from the loft using felt tape, but widespread damage requires professional replacement.
- Full replacement: Aged felt (typically over 25 years old) should be fully replaced with a modern membrane and new battens.
- Cost factors: Prices depend on the extent of damage, labour rates, and the type of materials used.
Results and Lasting Protection
The completed project restored full protection and stability to the roof. With new breathable felt, treated battens, and properly sealed leadwork, the property is now fully weatherproof and structurally sound. These improvements not only prevent future leaks but also extend the life of the roof for many years to come.
