Understanding Your Roof Valley: A Vital Water Channel

A roof valley is where two sloping roof sections meet, forming a V-shape. Its purpose is to efficiently channel rainwater and melting snow off your roof and down into your guttering system. Given the sheer volume of water it manages, the valley area experiences significant stress and wear over time. Traditionally lined with lead, or sometimes with felt or modern fibreglass, the integrity of this crucial junction is paramount. Over years, lead can crack or lift, felt can perish, or the mortar bedding can fail, leading to frustrating and potentially damaging water ingress into your property. Prompt repair is essential to prevent more costly structural issues down the line.

Who We Are

Key Signs Your Roof Valley Needs Attention

Catching a problem early can save you a great deal of money and hassle. Keep an eye out for these common indicators that your roof valley might be failing:

  • Visible Water Stains: Damp patches or discolouration on the ceiling or walls directly below the valley are a clear sign of water ingress.
  • Missing or Cracked Leadwork: If you can safely observe your roof, look for any displaced, cracked, or missing lead flashing in the valley.
  • Perished Felt or Gaps: For felt-lined valleys, look for bubbling, tearing, or general deterioration.
  • Moss or Debris Build-up: Accumulated moss, leaves, or other debris can block the valley, causing water to back up and find its way under tiles.
  • Dripping Sounds: Any persistent dripping sounds inside your attic or loft, especially during or after rain, warrant immediate investigation.
  • Broken or Displaced Tiles: While not directly the valley, slipped or broken tiles adjacent to the valley can lead to water bypassing the system.

Our Thorough Roof Valley Repair Process

When you call ST Builders, our experienced team will conduct a meticulous inspection of your roof valley, identifying the exact cause and extent of the damage. We pride ourselves on providing clear, no-obligation quotes before any work begins, so you understand the scope and cost involved. Depending on the issue, our repair process typically includes:

  • Safe Access: Utilising appropriate high-level access equipment to reach the affected area safely.
  • Removal of Damaged Materials: Carefully stripping back any failed lead, felt, or mortar to expose the underlying structure.
  • Preparation: Cleaning the area thoroughly, removing old debris, and preparing the underlying roofing battens and breather membrane if necessary.
  • Expert Re-Lining: We specialise in replacing old, worn-out valleys with durable, high-quality materials. This often involves new leadwork, laid and dressed with precision for a watertight seal, or installing modern, long-lasting fibreglass (GRP) valley systems which offer a seamless finish. We can also repair or re-bed dislodged interlocking tiles or plain tiles adjacent to the valley.
  • Finishing Touches: Reinstating roof tiles, ensuring proper overlap and water flow, and making certain the entire roofline, including any associated fascias and soffits, is secure.
