Introduction
A leaking roof is more than just an inconvenience—it can lead to interior damage, mould growth, and costly structural problems if left unchecked. In the unpredictable British climate, homes in Thurmaston, Leicestershire are no strangers to heavy rain, frost, and strong winds, all of which put roofs under constant stress.
At Thurmaston Roofing Repairs, we’ve dealt with every type of roofing issue imaginable. To help homeowners stay one step ahead, we’ve compiled a list of the 10 most common causes of roof leaks in the UK—and how to spot them before they lead to bigger problems.
1. Broken or Slipped Tiles
Tile movement or breakage is a leading cause of water ingress, especially after storms or heavy winds.
- Cracked or missing tiles allow rain to enter
- Usually visible from the ground or attic
- Can lead to widespread damp patches indoors
2. Damaged Flashing
Flashing protects roof joints and edges, particularly around chimneys and skylights. If it lifts or corrodes, leaks follow quickly.
- Common in older properties with worn lead flashing
- Water tends to enter near chimneys, dormers or vents
- Often worsened by poor previous repairs
3. Clogged Gutters and Downpipes
When gutters are blocked with leaves or moss, water overflows onto the roof or seeps into walls.
- Causes water pooling along the roof edge
- Accelerates fascia and soffit deterioration
- May lead to internal leaks near ceiling edges
4. Cracked or Perished Roof Felt
Roofing felt acts as a waterproof barrier beneath tiles or slates. Over time, it can split or deteriorate.
- Often causes hidden leaks behind walls or ceilings
- Hard to detect without professional inspection
- Typically found in older installations
5. Faulty or Worn Sealant
Sealants around vents, solar panels, or joints can crack with age or temperature changes.
- Causes leaks near fixtures or roof penetrations
- May go unnoticed until damp appears
- Sealant should be checked and replaced regularly
6. Poor Roof Installation
Shoddy workmanship can compromise even the best materials. Incorrect tile overlap, underlay installation, or flashing placement are common culprits.
- Leaks may appear soon after installation
- Repairs often involve correcting multiple areas
- Important to use certified professionals for all roof work
7. Moss and Algae Build-Up
Moss traps moisture, which can lift tiles and damage underlayers over time.
- Particularly common in shaded or north-facing roofs
- Can block drainage paths or gutters
- Regular cleaning is essential
8. Condensation in the Loft
What appears to be a roof leak may actually be condensation forming inside your loft due to poor ventilation.
- Causes wet insulation and mould
- Often mistaken for roof penetration
- Insulation and airflow improvements are key
9. Ice Damming in Cold Weather
When heat from the house melts snow on the roof, it can refreeze at the eaves and create ice dams, allowing water to back up under the tiles.
- More common in colder parts of the UK
- Hard to detect until thaw causes leak
- Proper insulation helps prevent this issue
10. Ageing Roof Materials
Simply put, roofs don’t last forever. Over time, even quality materials degrade, leaving the roof vulnerable to leaks.
- Signs include sagging, loose materials, and discolouration
- Water may enter in multiple spots
- Complete reroofing may be necessary

Roof leaks can start small but escalate rapidly. Identifying the source early can save you significant expense and stress. Whether it’s a cracked tile, faulty flashing, or poor ventilation, addressing the issue promptly ensures your home stays dry and structurally sound.
