Pitched roofs are designed to direct water away efficiently, yet leaks can still develop over time. In many cases, the cause is not immediately obvious and may originate from small defects that gradually worsen. For property owners in Cotgrave, Nottingham, understanding what typically causes pitched roofs to leak can help identify problems early and protect the roof’s overall condition.
Below are five of the most common causes of leaks in pitched roofing systems.
1. Slipped, Cracked, or Missing Roof Tiles
Roof tiles form the first line of defence against the weather. When tiles slip, crack, or go missing, gaps are created that allow rainwater to penetrate beneath the roof covering. Even a single displaced tile can lead to moisture entering the roof structure, particularly during prolonged or wind-driven rainfall.
2. Worn or Damaged Roof Underlay
Beneath the tiles sits the roof underlay, which provides secondary protection against moisture. Over time, underlay can deteriorate due to age, UV exposure, or previous water ingress. Once compromised, it becomes less effective at channelling water away, increasing the risk of leaks reaching internal areas.
3. Faulty Flashing Around Roof Features
Flashing is used to seal vulnerable points where the roof meets chimneys, walls, or other structural features. If flashing becomes loose, cracked, or poorly fitted, water can seep through these junctions. Flashing defects are a common source of leaks, particularly where movement or weather exposure has taken its toll.
4. Blocked Valleys and Guttering
Roof valleys and gutters play a vital role in directing rainwater away from the roof. When debris such as leaves, moss, or silt builds up, water can back up and overflow beneath tiles or into roof edges. Persistent pooling increases the likelihood of leaks forming over time.
5. Deterioration of Ridge or Hip Tiles
Ridge and hip tiles protect the highest points of a pitched roof and help secure the overall structure. As mortar or fixings degrade, gaps can form that allow water to enter. Because these areas are fully exposed to the elements, even minor deterioration can lead to leaks if not addressed promptly.
Why Early Attention Is Important
Roof leaks rarely resolve on their own. Left unchecked, even small amounts of water ingress can cause damage to timbers, insulation, and ceilings. Identifying the cause early allows repairs to be targeted and effective, helping prevent wider issues from developing.
