What Is Roof Repointing?

Ridge tiles (also called Ridge Caps or capping tiles) are the most important tiles on the roof, providing the first line of defence against water damage. Pointing is cement applied to the exposed edges of ridge tiles to improve a roof’s integrity and seal it against water and moisture. This cement can wear down over time, making repointing necessary.

Traditionally, repointing a roof was done with a sand and cement mixture, but today, flexible repointing materials are used that minimise the problems of shrinkage and cracking that can happen with cement.

How to know if your roof needs to be re-pointed? 

Roof repointing may be needed if:

  • Your roof is leaking or there’s moisture in your roof cavity
  • You can see gaps in the mortar around tiles
  • Roof tiles are loose or missing
  • Fragments of roof tiles or cement are found in the gutters
  • Your home was built before 1995, as it may have cement mortar that can come loose
