Ridge Capping, Rebedding & Pointing

Ridge capping covers the ridge of the roof, or where two tiled roof surfaces meet. Ridge capping is necessary to seal the gap so the roof is watertight.

The condition of the ridge capping will determine its functionality. Over time the mortar bedding and flexible pointing (flexible cement type product) deteriorates, and can become loose, cracked and fall away. This leaves gaps in the roof where water can penetrate and will most likely result in costly water/moisture damage to the roof and possibly ceilings below. Loose tiles can also become dislodged in heavy storms creating a much larger opening to the roof where the risk of damage is much higher. Ridge capping that is in poor condition with misaligned ridge caps and cracked mortar can also make the building look old and poorly maintained.

Why ridge capping needs rebedding and pointing

Tiled roofs are a long lasting and durable roof covering. However, the effects of wind, rain, sun, and freezing cold causes the mortar to eventually break down to the point that it’s quite “chalky” and reduces to a crumbling mass. 

Fluctuations in temperature cause the timbers in the roof to expand and contract. These roof movements cause the mortar to crack and breaks the bond between the tiles and the ridge capping. Weight and gravity also cause movement. Tiled roofs are enormously heavy and can cause the timber to sag and eventually even break under load. We would fully inspect the roof to ensure it is okay in all aspects when carrying out a re bed and point, and would replace any broken battens and or tiles on the roof.

If left too long the ridge capping can become loose and very unstable. It is always better to get the maintenance done long before there is a risk of water damage to your home or building.

The process

Remove the ridge capping

All ridge cap tiles are removed and the old mortar is removed to create a nice clean surface. All old mortar and any other debris is removed from site and recycled. 

Rebedding

Using a bedding jig to ensure the ridge capping is perfectly aligned, we lay a fresh bed of mortar on the rop row of tiles, and lay the ridge tiles back onto this fresh bedding. 

Pointing

A flexible pointing is then used to point the ridge capping, we careful fill all gaps to ensure there is a strong bond between the ridge capping, new mortar and roof tile. The pointing also creates a neat finish with a professional look. We provide a 10 year guarantee on all ridge capping work

Gable ends

Some roofs have ends with an inclined surface (an incline from the gutter up to the ridge), these ends of the roof can be either bedded and pointed like the ridge capping, or in some cases they have a gable cover (a metal fascia to create the weather seal). If the ends have no covers, and the pointing is cracked and/or loose, then we would also quote to re bed and point these gable ends. In most instances, we would replace the cement sheeting (fibro) that is nailed to the fascia and we would then bed the tiles onto this fibro strip.
