Painting – Cleaning and Re pointing Roof Tiles

All roofing requires some maintenance and roof tiles are no different. Tiles are a long lasting roofing solution however they do require re pointing every 10 years or so.

Repointing is simply the re – bedding of ┬áthe ridge cap. Ridge capping is held down with mortar, and as roofs age the mortar will naturally weaken. This is the main cause of tile roof failure, and generally this is during high winds when capping can become dislodged and cause leaking.

Flexible pointing is available, and it does have its advantages although it can be difficult to remove. Regular re pointing of ridge capping is one way of maintaining roof tiles.

Many companies offer painting of roof tiles, in general terracotta roof tiles should not be painted, if they are they will require continual maintenance. Painting of roof tiles is generally a cosmetic, modern roof tiles are often guaranteed for 25 + years. So painting might make your roof ‘look good’ for a few years but will need to be redone every 3 – 4 years and in general will not have any structural advantages or prevent leaks.

The main maintenance for tiled roofs is keeping them clean and clear of leaves and other debris.

So in terms of maintenance

  • Ridge Capping checked and or replaced every 10 years
  • Cracked or broken Tiles replaced
  • Any tiles that ‘move’ are reseated
  • Valleys and gutters kept clear of debris
  • Lichen and moss are generally not a problem unless they block drainage.
