Roof Repointing: Issues & Prevention

Roof repointing – a routine home maintenance task that involves the repairing of mortar joints between roof bricks or stones. Sound simple enough, right? However, if not executed correctly, it can result in various problems that jeopardize your roof’s integrity and compromise home safety. We’re going to go over some common issues arising from improper roof repointing and steps you can take to prevent them.

Insufficient Preparation

A primary cause of unsuccessful roof repointing is inadequate preparation. Thoroughly inspecting the roof for damage or wear-and-tear before commencing work is crucial.

Keep an eye out for loose or cracked tiles, damaged flashing, and other potential issues. Ignoring these problems prior to repointing may lead to escalated damage over time. Addressing these issues beforehand is essential to ensure the longevity of the repointed roof.

Incorrect Mortar Mix

Choosing an inappropriate mortar mix is another prevalent issue in roof repointing. The mortar used should match the original composition and strength of the existing mortar. Deviating from the correct type or ratio can result in structural problems and weaken the roof.

Consultation with a professional or doing extensive research is recommended to choose the correct mortar mix for your specific roof before getting started with any repointing work.

Inappropriate Tools & Techniques

Successful roof repointing requires the use of specific tools and techniques. Using the wrong tools or techniques may lead to uneven, weak, or incomplete joint filling.

For instance, substituting a power grinder for a chisel during old mortar removal can cause unnecessary damage to bricks or stones. So always make sure to use the right tools.

Hasty Work

Roof repointing is a task that should not be rushed. It demands time, patience, and attention to detail.

Rushed work can result in sloppy mortar application, uneven joint filling, or missed spots. Taking the proper time and care to complete the job will prevent the need for future repairs.

Insufficient Weather Protection

Weather protection is extremely important during roof repointing. Wet or damp conditions can impact mortar strength and durability, leading to cracks and damage over time. Especially after a heavy Perth storm season.

It’s recommended to schedule repointing during dry weather. If weather can’t be helped, you should cover newly repointed areas with plastic sheeting in case of rain, to avoid any potential damage during the curing process.

In conclusion, while roof repointing may initially seem quite straightforward at first, it’s far from easy. Meticulous preparation, use of appropriate tools and techniques, and patience are essential for successful execution. Proper research and preparation can save you from many headaches down the road.
