5 Roof Repairs Your Pro Painters Shouldn’t Forget

For the unique weather patterns in Australia, the best roofing materials include four types: steel, terracotta, and concrete tile, zinc and copper cladding, or bluestone and synthetic slate. Each type has its range of pricing, heat transfer, beauty, and longevity.

With intermittent wind gusts, constant heat alternating with storms, and cold air, the roof is the first layer of protection and – because it’s out of sight for the most part – the last to be repaired or maintained, only it’s leaking, uncomfortable, or unsafe. But why wait?

Many homes and properties in Brisbane are now doing yearly maintenance checks before the weather intensifies. From top to bottom, tiled roofs should be closely checked for ridges and re-pointing.

If these are unfamiliar terms for you, this 5-minute read will practically make you an expert … and more.

1.What is ridge capping?

The term “ridge” refers to the peak or the highest point on a roof where two roof areas intersect. At the same time, “ridge” also refers to the beam or board that is used to build the ridge.
Ridge caps are the angled tiles that cover the ridge, or the highest points on a roof.
Ridge caps are fixed to the ridge in two ways: first by bedding, and then by pointing.
However, in the case of metal ridge caps, screws are used instead.

2.What is pointing & bedding?

The term “bedding” refers to the mix of sand & cement or mortar that is used to bond the tiles and the ridge caps to the ridge of the roof.

The term “pointing” is the process of creating a stronger seal by adding a second layer of mortar on top of the bedding.

Repointing is the process of removing loose or broken mortar and replacing it with new bedding. Often, repointing is done when the roof tiles are still good but the ridges have started to deteriorate.

3.When does a roof need re-pointing or re-bedding?

Re-pointing: Look at the condition of the mortar between the roof tiles. Pay close attention to the ridge caps. If you see any gaps or cracks where moisture, dust, or insects can enter, then the roof needs re-pointing.

If ignored, these breaks, cracks, or gaps in the mortar can only increase in size as heat, cold, and moisture continue to expand and contract the roof. Eventually, the tiles will loosen and may get blown away or fall off and cause damage or injury.

Re-bedding. It’s not that easy to check if the roof needs re-bedding. Typically, a roof should be inspected twice every ten years to see if the mortar is wearing out and allowing moisture or water to enter. Ask a qualified roofer to inspect the roof.

4.What is re-bedding and re-pointing?

Re-bedding means removing the existing bedding and pointing mortar, including all accumulated dust and debris. The area is then allowed to completely dry out.

A new mix of three (3) parts roofers’ loam and one (1) part cement is applied by trowel to the roof tiles, which are then covered by ridge capping.

After the bedding dries, the pointing is applied to the sides of the ridge as well as to the collars where the ridges overlap. This waterproofs the ridges and secures them from wind uplift.

5.What is dry ridge conversion?

Wet ridge systems using mortar bedded ridges are cheap, easy to install, and many a relatively competent roofer can quickly apply a wet ridge repair on a roof.

However, the guarantee period is shorter compared to a dry ridge roof. Over time, cement shrinks, chunks break away and fall. Future repairs are always expected.

The dry ridge method is more expensive but longer-lasting. The ridge tiles or hip ridge tiles are fixed to the roof with screws and clamps, not mortar. This system is stronger and adds extra ventilation to the entire roof. However, for a quick and cheap temporary fix, a wet ridge repair works.
