Main Causes of Roof Deterioration in Perth

Main Causes of Roof Deterioration in Perth

The primary purpose of roofs is to protect everything within your home. Hence, they are made sturdy since they are exposed to all sorts of harsh elements. However, no matter how strong roofings nowadays are, they will still deteriorate due to different factors such as weather, debris buildup, and nesting animals, among others.

It’s good that Perth Roof Restoration & Repair is one call away if you ever have any issues with your roofs. They provide various roofing services within Perth and nearby suburbs.

Top Enemies of Australian Roofs

Mould and Mildew

Mould and mildew are not only unsightly and unhealthy. Their proliferating spores can eventually destroy roofs by gradually rotting their core. If left untreated, prolonged exposure can weaken the materials, eventually leading to more serious problems and significant expenditures in the offing.

Another concern is they can also potentially attract rodents like rats, mice, and squirrels. Without regular inspection, you might eventually have a pest-infested household as they discover the nooks and crannies of the entire building.

Nesting Animals

What is Australia without all sorts of animals? Perth, in particular, has been dealing with pests and even insects. However, roofs’ enemies include birds, possums, and rodents. No matter how adorable some of them can be, they might feel so comfortable getting near people that they take shelter in your home through your roof.

These can eventually lead to damage as they collect debris that clogs the gutters, creates holes in the roof, or even wrecks the insulation system. Another possibility is that they can start to munch on roof materials or just take away parts to create their nests. If any or all of these happen, expect to deal with roof leaks, if not significant damages that lead to unnecessary massive spending.

Overgrown Trees

Overgrown Trees

Plants and trees add to the overall aesthetics of your property, not to mention the pleasant atmosphere they create with all the shades and breezes they bring. However, if you have overgrown trees that touch parts of your home, particularly the roof, you might want to trim the leaves and branches.

Leaving these sitting on the roof for longer can create damage as they create moisture buildup where moss and mould thrive. This eventually leads to deterioration and eventually damaging your roofing system altogether.

Poor Roof Installation

No high-quality materials can ensure a lasting roofing system if not correctly installed. Poor repairs are the same situation. Surprisingly, improper installation is quite commonplace in the roofing industry.  

Poor installation and repairs often lead to leaks that not only bring so much stress as they happen but, unfortunately, also the start of your roof’s deterioration if not resolved immediately. Hence, it is essential to always choose to get the services of reputable roof installers and repair professionals such as Perth Roof Restoration & Repair if you live within the city or the surrounding areas. They employ highly qualified and fully trained roof installers, roof carpenters, roof plumbers, and roof tilers so you can have peace of mind.

Poor Roof Ventilation

Another often overlooked factor in a sound roofing system is the ventilation. State-of-the-art materials, proper installation, and regular maintenance are often not enough. Adequate air circulation is crucial in keeping the roof moisture-free, as humidity can stimulate mould and mildew growth, leading to premature deterioration.

The thing with damage caused by lousy ventilation is that it can get so severe when not discovered on time. More often than not, repair is not enough, and you might need a more expensive remedy like roof restoration or even replacing the entire roof system.


Even the sturdiest roofs out there don’t stand a chance against the might of a raging storm, particularly if you live in areas where tropical cyclones are a regular occurrence. Not only do you worry about the damage caused by the strong winds to your roofs, but also the water accumulation in some parts of the structure.

Structural damage left by the storm is very obvious and often necessitates immediate remedies. However, pooling and puddling often go unnoticed if not thoroughly checked. If these go on for some time and are not drained immediately, expect severe damage, such as an unwelcome load that can cause sagging and creates an environment for mould and mildew to grow.

Wear and Tear Due to Age

All roofs have an expected lifespan, depending on their materials’ composition and quality. However, the issues listed above can cut this much shorter. In a perfect world where all of these do not exist, all structural materials go through a natural phase of wear and tear due to the roof’s age.

As they are nearing the end of their service life, you’ll notice overall structural weakening and other signs of ageing such as bald spots, brittle, curling, shingles and granule loss, or worse, sagging.

Roof Maintenance

If you own a property in Perth, Australia, whether residential or commercial, professionals in the industry cannot stress enough how important regular roof maintenance is. Since your roof is your first line of defence against the harmful elements in the environment, such as the sun and all kinds of precipitation, it is important to ensure that it is well-maintained to continue enjoying comfort.

At the very least, have your roof inspected once a year. The most ideal would be twice a year. However, you don’t have to wait that long or observe that interval if you experience a heavy downpour. Inspect your roof right away to see whether rain has caused damage or if it has collected water somewhere in the system.

By doing roof inspection and maintenance regularly, you will be able to catch any issues at their earliest signs and be able to make repairs that will not cost much. If you notice damage to your roof too late, you will have to deal with major repairs or, worse, replacement, which not only would cost an arm and a leg but would also cause inconvenience to your entire household or your business.
