Fixing a ridge cap or capping involves repairing or replacing the material that covers the ridge of a roof. Ridge capping is typically made of cement mortar, metal, or plastic and serves as a protective cover for the intersection of two sloping roof surfaces.

Here are the steps to fix ridge capping:

  1. Remove the old ridge capping material: This involves carefully removing the old ridge capping material, taking care not to damage the underlying roof structure.
  2. Inspect the roof structure: Once the old ridge capping material has been removed, inspect the underlying roof structure for any signs of damage or deterioration that may need to be repaired.
  3. Replace damaged roof tiles or slates: If any of the roof tiles or slates are damaged, they should be replaced before installing the new ridge capping.
  4. Install the new ridge capping material: The new ridge capping material should be installed using cement mortar or another appropriate adhesive. The material should be secured in place and pressed firmly onto the roof surface to ensure a secure bond.
  5. Point the new ridge capping: Once the new ridge capping material is installed, the gaps between the tiles or slates and the ridge capping should be filled with mortar or sealant to create a water-tight seal.
