Roof leaks are a serious issue for homeowners and building managers. Left untreated, they can lead to water damage, mould growth, structural problems, and costly repairs. Understanding the common causes of roof leaks for different roof types—tiled pitched roofs, metal pitched roofs, and concrete flat roofs—can help you detect problems early and protect your property.
1. Tiled Pitched Roof
Tiled pitched roofs are popular for their aesthetics and durability. However, they are not immune to leaks.
Common Causes
- Broken or Cracked Tiles: Severe weather, falling branches, or natural wear and tear can crack or displace tiles, allowing water to penetrate
- Damaged Waterproofing Layer: The waterproof layer beneath the tiles can deteriorate over time, causing leaks even when the tiles appear intact
- Blocked Gutters: Accumulated debris can cause water to overflow, seeping under tiles and into the roof structure.
2. Metal Pitched Roof
Metal roofs are durable, lightweight, and low-maintenance but still susceptible to leaks if not maintained properly.
Common Causes
- Loose Fasteners: Screws or bolts that hold metal panels can loosen over time, creating gaps for water entry
- Seam and Joint Failures: Improper sealing of seams or worn-out sealants can allow water to penetrate
- Corrosion and Rust: Moisture can cause rust on older metal roofs, weakening the structure.
- Improper Installation: Poor installation or flashing errors can compromise waterproofing
3. Concrete Flat Roof
Concrete flat roofs are common in modern architecture but have their own unique challenges when it comes to leaks.
Common Causes
- Ponding Water: Flat roofs that are poorly sloped or blocked drains can accumulate water, causing cracks and leaks
- Cracks in Concrete: Thermal expansion, heavy loads, or settling can create cracks for water to seep through
- Degraded Waterproof Membrane: Many flat roofs rely on membranes that can blister, peel, or deteriorate over time
- Blocked Drains and Scuppers: Debris or leaves can prevent proper drainage, increasing the risk of water damage
Signs of a Roof Leak
Recognising a roof leak early is crucial. Common signs include:
- Water stains or discoloration on ceilings and walls
- Damp insulation in the attic or ceiling void
- Mould or mildew growth indoors
- Dripping water during rainfall or after storms
Tip: Even small leaks can escalate quickly, so address them promptly.
