Re-Pointing

Flexible pointing compound was first introduced in Australia only a few decades ago. When a new tiled roof is installed, flexible pointing is applied over the top of fresh mortar that bed the ridge caps to the roof tiles. The flexible pointing compound seals this exposed mortar and, as the names suggests, dries into a flexible compound that is far less prone to cracking with any movement of the roof frame and house. Flexible pointing also complies to Australian Standards for mechanically securing ridge capping. Meaning, it eliminates the need for screws or brackets and clips to ensure ridge caps are not dislodged during storms. This applies for most wind rating categories in south Queensland.

Repointing is a very important maintenance task to ensure a watertight roof. Repointing of the ridge caps should occur when any cracks or deterioration is evident in the flexible pointing, which is generally around 10-15 years.

Here’s a general overview of the re-pointing process for roof tiles

Inspection: An assessment is conducted to determine areas and if repointing is the correct course of action. During an inspection we look for gaps, cracks, or signs of deteriorated ridge pointing and or mortar. It’s important to assess the overall condition of the roof and determine the extent of the re-pointing needed. 

Re-pointing: In preparation we drill through to clear out all weep holes, grind back the ridge cap edges and remove any loose mortar. We then blow off all remaining dirt, dust and smaller particles to provide a suitable surface and maximum adhesion for the new flexible pointing. Using a pointing trowel we then neatly apply the colour matched flexible pointing compound to all edges of the ridge caps including overlapping collars as well as any barge caps required. 

Finishing touches: Once the flexible pointing has partially dried, we clear though the new weep holes and meticulously check the continuity of the fresh pointing to ensure a neat, professional, and watertight finish is achieved.

Re-Pointing

Repointing a tiled roof is a vital maintenance process that involves applying fresh flexible pointing to ridge caps in order. to seal, secure and provide a watertight finish. in Australia, where varying weather conditions and exposure to elements will degrade pointing over time. repointing becomes necessary to ensure the structural integrity, water-tightness, and overall longevity of tiled roofs. This process typically involves removing damaged or deteriorated pointing by wire brush or wet grinding to prepare the surface and redrilling or cleaning the weep holes. New flexible pointing compound is then applied to secure the ridge caps in place and prevent water infiltration.

Benefits of Re-pointing a
Tiled Roof in Australia

RE-ROOFING

1. Leak Prevention

Over time, mortar and pointing can deteriorate due to exposure to rain, wind, and sunlight. Repointing helps maintain the watertight seal between the ridge caps and tiles, preventing water from seeping through and causing leaks and water damage to the underlying roof structure.

2. Structural Integrity

Securing and sealing ridge caps play a very crucial role in the functionality of tiled roofs. Repointing ensures that tiles remain properly anchored, minimising the risk of tiles becoming dislodged or loosened during extreme weather events.Extended Roof Lifespan: By addressing deteriorating mortar and pointing, repointing can help extend the overall lifespan of a tiled roof. Well-maintained ridge caps contribute to the long-term durability of the roofing system, reducing the need for more extensive and costly repairs down the line.

3. Aesthetic Enhancement

Repointing can enhance the visual appearance of the roof. Freshly repointed mortar can provide a clean and uniform look to the roof, improving the curb appeal and overall aesthetics of the property

4. Energy Efficiency

Properly repointed mortar joints contribute to better insulation and ventilation within the roof space. This can help regulate indoor temperatures, potentially leading to improved energy efficiency and reduced utility bills.

5. Prevention of Structural Damage

Damaged mortar can lead to water infiltration, which may compromise the underlying roof structure over time. Repointing helps prevent potential structural damage caused by moisture penetration.
