As a leading roofing company in Kent, we have years of experience in providing top-notch roofing services, including valley sealing. In this article, we will guide you through the process of sealing roof valleys, highlighting the key materials and techniques used.

Roof valleys are the areas where two slopes of a roof meet, forming a V-shaped channel. These areas are prone to water accumulation, making them susceptible to leaks and damage. Proper sealing of roof valleys is crucial to ensure the integrity of your roof.

There are several materials used for sealing roof valleys, including:

• Lead: A popular choice for valley sealing, lead is a durable and long-lasting material that can withstand harsh weather conditions.
• Mortar: A mixture of cement, sand, and water, mortar is used to seal the valley and provide a watertight seal.
• Leadwork: Leadwork involves the use of lead sheets to cover the valley, providing a durable and long-lasting seal.

1. Inspect the Valley: Before starting the sealing process, inspect the valley for any signs of damage or wear. Check for loose or missing shingles, and ensure the underlay is intact.
2. Clean the Valley: Clean the valley of any debris, dirt, or old sealant. This will ensure a smooth and even application of the new sealant.
3. Apply a New Underlay: If the existing underlay is damaged, apply a new one to ensure a watertight seal.
4. Install Lead or Mortar: Install lead sheets or apply mortar to the valley, ensuring a smooth and even application.
5. Seal the Valley: Use a leadwork technique to seal the valley, ensuring a watertight seal.

• Use a minimum of 1.5mm lead: This will ensure a durable and long-lasting seal.
• Use a code-compliant underlay: Ensure the underlay meets the relevant building codes and regulations.
• Use a reputable roofing company: A reputable roofing company, such as A1 Roofing Canterbury, will ensure the job is done correctly and to a high standard.
