The process of rebed and pointing will depend on whether or not you have cement or terracotta tiles. David Heeley from DJ Heeley Roof restoration will be able to determine which approach will be the most effective after an onsite inspection.
Cement tile process for a re bed and re point starts with the ridge caps being removed and all of the old sand and cement being chipped off and disposed of.
Once this is completed all the broken and chipped tiles are replaced and the ridge caps are re bedded back into position using sand and cement.
The re pointing is the final process and is done using a flexible pre mixed compound in a range of colours.
We do our best to match the roof colour to make it look as natural as possible.
The terracotta tile process is fairly simple beginning with an anti-fungal if needed, most dont as the high pressure cleaner gets most moss off easily in the case that the roof is full of moss we spray the product on and it kills the algae and fungi on the tiles. Pressure cleaning is the next step this removes all of the moss and cleans the surface of the tile which makes it look like new again.
Once the cleaning has been done then its time for the ridge caps to be removed, DJ Heeley dont do partial re beds and re points. We do all of the ridge caps because in most cases the cement is the same age and should all be removed at the same time.
The ridge caps are removed and all the sand and cement is chipped off the tiles, the broken and chipped tiles are replaced and then the ridge caps are placed back into a dry ridge position meaning without cement ready for the re bed.
The ridge caps are re bedded into position using sand and cement and then it is left to set.
Once set the re pointing process is completed, DJ Heeley Roof Restoration use a few different flexible compounds depending on weather and colour required they all have a 10 year guarantee.
Cement mortar used to be used for roof pointing but has been replace by flexible pointing compounds. Flexible pointing expands and contracts with changing weather conditions.
If your pointing has cracked or deteriorated, your roof is far more likely to start to leak which will cause damage to your home.
Flexible roof pointing has been used in Australia since 1995. If your house does not have flexible pointing, we strongly recommend your roof be re-pointed. Cement mortar pointing is far more likely to crack and allow water in your roof.
DJ Heeley Roof Restoration recommend that your ridge caps be re bedded and re pointed at least once every 10 years.
