Repointing Ridge Caps Process

Repointing ridge caps are an important process that in sum, repairs and restores the mortar joint between the ridge tiles of a roof.

Over time, the mortar in the ridge cap can become damaged or worn, which can lead to leaks, cracks, and other issues. In fact, ridge cap issues are the usual suspects when it comes to most roof leaking issues that we see in Perth.

Repointing the ridge cap helps to prevent these problems by restoring the integrity of the mortar joint to ensure that the roof is secure and watertight – or in other words – leakproof.

Below is a step-by-step guide to the repointing ridge cap process:

1. Inspection: Before starting the repointing process, our team takes a detailed inspection of the suspected ridge cap and the surrounding area, to determine the extent of the damage alongside detecting any other issues that may need to be addressed.
   
2. Preparation: Next, we ensure the area around the ridge cap is cleared and cleaned. With any loose or damaged mortar being removed safely and professionally. The ridge cap itself, is also cleaned and any cracks we find are filled with a suitable filler.
   
3. Mixing the mortar: We then start mixing the appropriate according to the manufacturer’s instructions. It is important to use the right type of mortar, as some mortars are designed specifically for use on roofing materials, whilst others are not.
   
4. Repointing the ridge cap: Once the mortar is mixed, we use a pointing trowel to apply the mortar into the joint between the ridge tiles. The joint should be shaped to match the original joint, and the surface of the mortar should be smoothed out. With all excess being removed and cleaned.
   
5. Curing: After the repointing process is complete, the mortar should be left to cure for the recommended amount of time, which is typically 24 to 48 hours. During this time, the mortar should be protected from moisture and the elements.
   
6. Final inspection: Once the mortar has cured, our team will give the ridge cap a final inspection to ensure that the repointing process went smoothly with no leaks or cracks in the joint. In the unlikely event where issues should arise, we will then continue the repointing process until the ridge cap is secure and watertight.

It is important to note that repointing a ridge cap is a complex and technical process that should only be carried out by professional roofers.
