Project Details
A homeowner contacted us after noticing ceiling stains and a damp smell in the loft. Investigation revealed that poorly installed vent detailing and deteriorated flashing had been allowing water ingress over time. We identified the source of the leak, replaced the affected sections, and restored the roof’s integrity without the need for a full replacement.
What we did
This project required careful investigation followed by targeted repair work.
Leak detection & inspection
We began with a detailed inspection to identify the source of the issue.
Investigated internal staining and moisture within the loft space
Identified deteriorated flashing around a roof vent
Checked surrounding tiles and underlay for signs of damage
Confirmed the source of water ingress through controlled testing
Repair & restoration
Focused repairs carried out with attention to detail.
Carefully removed tiles in the affected area
Replaced damaged flashing and sealed vent detailing
Installed new synthetic underlay to exposed sections
Re-tiled using colour-matched materials
Resealed surrounding areas to ensure a weather-tight finish
Challenges we faced
A minor defect with wider implications.
Localised mould growth in the loft due to prolonged moisture exposure
Sourcing matching tiles for an older roof profile
Restricted working space around vents and roof junctions
Why this project stands out
A targeted repair avoided unnecessary replacement work.
Cost-effective solution for a localised issue
No full strip-out required
Efficient turnaround (2 days including curing time)
Extended the life of the existing roof system by several years
Final result
The leak was fully resolved, the interior protected, and the repaired area blends seamlessly with the existing roof.
