In this article, we will provide you with a step-by-step guide on how to seal roof valleys in Reading.

A roof valley is the area where two slopes of a roof meet, forming a "V" shape. This area is prone to water accumulation, making it a common spot for leaks and damage. Roof valleys can be open or closed, with open valleys being more common in modern roofing.

Sealing roof valleys is essential to prevent water from entering your home and causing damage. Water can seep into the valley and flow under the tiles, leading to leaks and structural damage. Sealing the valley ensures that water flows freely off the roof, reducing the risk of damage and costly repairs.

To seal a roof valley, you will need the following materials:

• Flashing (preferably lead or EPDM)
• Mortar
• Tile adhesive
• Tiles (if necessary)
• Sealant (such as silicone or polyurethane)

1. Inspect the Valley: Before starting the sealing process, inspect the valley for any debris, dirt, or damaged tiles. Clean the area thoroughly to ensure a smooth sealing process.
2. Cut the Flashing: Cut the flashing to the required length, leaving a 150mm overlap at each end. This will ensure a watertight seal.
3. Apply Mortar: Apply a layer of mortar to the valley, spreading it evenly to cover the entire area.
4. Lay the Flashing: Place the flashing in the valley, ensuring it is centered and the overlaps are secure.
5. Secure the Flashing: Use tile adhesive to secure the flashing to the tiles, ensuring a watertight seal.
6. Seal the Edges: Apply sealant to the edges of the flashing, ensuring a watertight seal.
7. Replace Damaged Tiles: If necessary, replace any damaged tiles to ensure a watertight seal.

• Always use high-quality materials to ensure a long-lasting seal.
• Ensure the valley is clean and free of debris before sealing.
• Use a minimum of 150mm overlap when laying flashing.
• Apply sealant to the edges of the flashing to prevent water ingress.
• Consider using lead flashing, which is more durable and long-lasting than other materials.
