More than Just Aesthetics: The Toll of a Dirty Roof


A dirty roof is impossible to miss. With your roof covering up to 30% of the external view of your home, a grimy roof can convert a stunning, eye-catching home into an eye sore. Unfortunately, accumulated grime on the surface of your roof tiles is typically the first sign of a deeper underlying problem. A build-up of dirt and organic matter means a lack of maintenance, and a lack of maintenance means a higher likelihood of cracks and increased potential for underlying damage within the structural elements of your roof.

Getting your roof professionally inspected and cleaned by a licensed roofer is the absolute best way to ensure you’re maximising the longevity of your roof. Additionally, investing in expert cleaning will help you avoid paying tens of thousands of wasted dollars on reroofing.

We specialise in terracotta and concrete tile roof cleaning and have proudly serviced residential customers throughout Tasmania since 2013. Have peace of mind knowing you’re working with a fully licensed & insured team of roof cleaning experts. Our cleanup process involves:

  • A comprehensive pre-cleaning roof inspection
  • Completion of any required maintenance
  • Terracotta and concrete roof tile power washing
  • Clearing out your gutters of any excess plant matter
  • On-site roof repairs when needed
  • A double layer of biocide sterilising treatment to ensure lasting results

Here are the key reasons you should invest in a roof cleaning from our expert team of roofers:

Save Money on Unnecessary Roof Repairs

A dirty roof full of overgrown moss is a common sign it’s not maintained correctly. Moss especially loves to anchor itself onto the tiles’ surface and can contribute to dislodging your roofing elements, reducing the effectiveness of your roof in protecting your home from the elements. Overgrown moss can also be one of the first starting points for leaks and water intrusion, making routine roof cleaning a good way to preventing leaks.

Another common way moss and mould can damage your roof is via moisture retention. Moss and mould are excellent at trapping moisture against the roof’s surface. Unfortunately, prolonged moisture exposure can compromise the integrity of roofing materials (especially if it begins to seep into the underlying wooden structural elements). In addition, when left unchecked, accumulated moss and mould will continue to add weight to your roof, contributing to sagging. In the worst-case scenario, an unchecked roof can eventually lead to rotting, warping, and eventual degradation of the roof.

Repairing or even reroofing can cost a fortune. The enormous financial burden of roof repairs can add up to tens of thousands of dollars, so prevention through routine roof inspections and cleanings is the best way to safeguard your home and bank account. It will help you avoid hefty emergency repairs and callouts while keeping your maintenance costs minimal.

A Home You Can Take Pride In

A clean, well-maintained roof is striking and appealing, while a poorly maintained, dirty roof can stick out like a sore thumb. Accumulated growth and grime will create unsightly stains and discolouration, easily seen from a distance. This diminishes the overall appearance of your property, having a negative impact on curbside appeal.

Our expert roof cleaning services specialise in removing unsightly stains, moss, and debris to help restore your roof to its original pristine condition. Our team will help the visual appeal of your property stand out so you can own a home you can take pride in.

A Note: If your roof tiles are terracotta and made by Monier, it’s important to mention they will never fade and will continue to maintain their colour for decades. This is because the colour of the tiles is an attribute of the material from which it’s made. Any dull colour is due to the build-up of dirt, grime, and organic matter and is easily solved by a thorough roof cleaning.

Avoid Pest Infestations

Rodents, birds, and insects love to nest in mossy or mould-ridden roofs.Organic matter can attract insects that can seek refuge under your tiles or burrow into cement, decreasing the longevity of your roof. In addition, birds can also nest in your gutters, leading to a build-up of leaves and twigs, which increases the chance of leaks occurring and is also a bushfire hazard.

A regular roof cleaning is a great way to avoid forking out on unnecessary repairs caused by accumulated pest damage.

Work With the Best Roof Cleaners on the Market

A neglected roof with accumulated grime, mould, and moss is how pest infestations and costly repairs start. Working with our team of Roofers means peace of mind, knowing one of the most critical sections of your home will be left pristine and in 10/10 condition.

A common question you may be asking is if it’s worth investing in the expertise of a roofing expert to complete your cleaning. For example, consider hiring a pressure washing company without a background in roofing. Or you could even consider attempting your own cleaning?

We understand many of our clients may be looking for cost-effective ways to clean their roofs; unfortunately, there’s a range of ways the project can go south should the correct safety measures and training not come into play.

The Potential Risks to Avoid

When it comes to residential roofs, our team has seen it all. Any roof cleaning project has a range of complexities that must be adequately planned and accounted for. A clean not completed by a licensed Roofer or even a DIY cleaning can come with many risks that shouldn’t be overlooked

Here are some of the key reasons you should invest in a professional to clean your roof:

Avoid A Fall

Roof cleaning involves working at heights while standing on slippery tiles. This means inexperienced cleaners are, unfortunately, vulnerable to slips and falls (a substantial injury risk). As an added risk, your roof could be unsafe to bear weight without you realising it. For example, a sagging roof is a critical hazard that an untrained eye can often miss. Adding pressure to an already weak roof is a considerable hazard and should be addressed as an initial precaution.

Investing in an expert roof cleaner is the best way to protect yourself from slips and falls. Our trained Roofers employ the use of safety attire as well as fall protection gear to ensure the risk of falls is mitigated. Having received the necessary OHS training, combined with years of roofing experience, our team of roofers are highly comfortable working at heights and take every measure required to ensure they complete your roof cleaning safely.

Damage to Your Roof

Every roof clean we complete has a process and is ideal for your roof’s specific circumstances and needs. An inexperienced cleaner may risk substantially damaging the roof, potentially amounting to thousands of dollars in additional repairs. Using harsh chemicals, the wrong power washing methods, and incorrectly walking on your roof are all ways you can increase its rate of deterioration. This can increase the chance of tile damage, cracks, and, eventually, leaks occurring. The last thing you want is to take on your own roof cleaning only to require a costly restoration in the future to repair any previous damage.

Our trained roof cleaners know every section of your roof inside and out, knowing the appropriate cleaning methods for each. We use gentle (yet effective) cleaning tools and solutions that won’t compromise or damage your roof.

You May Miss Underlying Roof Issues

Unless you’re a roofing expert, you likely lack the knowledge to identify underlying issues with your roof, including cracks, worn cement, corroded flashing, structural problems, etc.

Often, before cleaning, we’ll find several critical issues that should first be addressed before we start a deep clean of our client’s roof. For example, pressure washing a roof with existing leaks can only exacerbate underlying issues and must be repaired as a first step. Should our team of roofers detect any problems, we’ll alert you and provide an appropriate and cost-effective solution.

Inadequate Results

The last thing you want is to fork out on a clean, only to find missed spots or a grime build-up soon into the future. In addition, the wrong chemicals and methods can accelerate deterioration and eventually lead to discolouration of your roof.

Working with our team means investing in the skills and expertise to ensure the best possible results for your roof. Our roof cleans focus on not only leaving it looking fantastic but also taking every measure we can to extend the longevity of your clean. For example, after every cleaning, we add two coats of gentle roof steriliser to deter future grime build-up and save you cash in the long term.

Injury From Tools and Equipment

If you’ve ever handled a pressure washer, you’ll know they’re extremely powerful and release water with substantial force! Operating cleaning tools, as well as chemical solutions, without the correct training, can lead to accidents or injuries.

Our roof cleaning experts know how to operate our industry-standard cleaning equipment safely and efficiently. They know exactly what tools and solutions to use and at what point of the cleaning process to ensure the risk of injury (and damage to your roof) is avoided.

Insurance Coverage and Liability

When getting a roof clean, make sure you read the fine print of your insurance. DIY cleaning, especially, could expose you to liability in the event of an accident, injury, or damage to your property.

In addition, working with a business without the appropriate liability insurance can be risky. Should your home be subject to any damage during the cleaning process, an inadequately insured business may lack the necessary funds to support the repairs, making the possibility of a lengthy, drawn-out legal process a consideration.

As insured roofers, both you and our team are protected. In the instance of a rare mishap, our insurance ensures that any accidental damage or injuries that occur during the cleaning process are appropriately addressed. Working with us guarantees a safer and more thorough cleaning process and provides you with peace of mind, knowing that any potential liabilities are adequately covered.

Make An Informed Decision for Your Roof
UV Protection

With high-quality tiles, a fresh new roof offers excellent reflective properties to prevent UV light from penetrating your home, keeping you comfortable and temperate.

Physical Protection

Your tiles are a physical barrier for falling trees, hail, or pests such as rats, possums, and birds from nesting in your attic. An uncompromised roof also protects your insulation.

Pollutant Barrier

Your roof is an essential barrier to the external environment, working in tangent with your ventilation to prevent pollutants and allergens from entering your living space.


With many residential building inspections failing on the roof, a new roof adds significant value to your home.

Foot Traffic

An immediate consideration is that foot traffic, including gutter cleaning, solar installations, etc., can cause roof tile cracks. A qualified roofer can immediately replace cracked tiles before any further damage starts.


Within as soon as ten years, the pointing of your roof can start showing signs of cracking (further worsened by foot traffic). A quick pointing touch-up is a simple way to prevent further damage.

Accumulated Grime

Within ten years, the first signs of moss and lichen will start to show (particularly in moist environments). A periodic powerwash is the best way to keep your roof looking fresh.

Dislodged End Cap

Usually one of the first things to go, your ridge cap end tile can start to feel the weight of gravity and begin to slide. This is an easy fix at this stage.

Cracked Pointing

More extensively cracked and peeling ridge pointing will start to show, exposing the mortar under your hip tiles (ridge caps). Should you address the issue soon enough, a qualified roofer could save the bedding with a cost-effective pointing touch-up.

Dislodged Flashings

Your roof’s flashings can become dislodged over time and may need replacement. A simple installation of a lead-free, adhesive flashing is a cost-effective way to prevent further damage.


At a minimum, we recommend a roofing inspection of your roof to have any routine maintenance complete and ensure your roof is in functional condition.

Accumulated Grime

Moss and lichen will continue to grow, making your roof look lacklustre and contributing to cracking of your pointing. A simple roof clean by an expert is a great way to nip this issue in the bud.

Dislodged Shell Cap

If your end ridge tile is not addressed soon, it can continue to slide and allow the tiles it sits on to begin to slide into your gutter.

Loose Ridge Caps

Ridge caps are likely loose at this point. When this occurs, complete cleaning and replacing bedding cement is required to ensure the ridges are refastened and stay in place.

Degraded Pointing

If left unattended, the pointing of your ridge caps (at a bare minimum) needs replacing to keep your ridge caps secure.

Faded Colour

With age, all roofs will lose their colour/glaze. Restoring this is for cosmetic purposes, but when all maintenance is completed, followed by re-sealing and painting, it will add a new lease of life to an old, bland roof.

Dislodged End Cap

By this stage, your end cap could have continued to slide off, leaving no weight on its under tiles. This not only looks terrible but also allows water ingress.

Replacement Required

At this point, your roof may be beyond repair. Moss could have penetrated under your tiles, unattended mechanical stress could leave your tiles riddled with cracks, and your ridge caps likely need complete repair. Unfortunately, complete reroofing may be the only solution.

Use our interactive tool to explore the long-term benefits of quality roofing:

Leak Protection

The roof tiles are designed to allow rain to run freely off your roof and into your gutter to prevent pooling on your roof’s surface.

Controlled Runoff

Your roof’s valleys act as a securely sealed, free-flowing channel to allow stormwater to run seamlessly into your gutters.

Leak Protection

The ridges of your roof are fastened with bedding cement and sealed with pointing mortar to prevent water ingress.

Leak Protection

Flashings are small pieces of metal placed around your roof’s joints to act as a tight and secure waterproofing barrier.

Weather Damage

Strong winds caused by storms can dislodge valley tiles. Having an expert roofer clip these back into place is an easy and cost-effective way to avoid further damage.

Accumulated Debris

Within ten years, debris and organic matter will start to fill in your gutter, increasing the chances of rust and water overflow. A simple, quick emptying of your gutter is the best way to avoid any issues.

Water Ingress

Any cracked and unattended pointing will start to make your roof vulnerable to water ingress, with a high chance of leaks beginning to move through your ceiling and into your attic.

Lost Flashings

Flashings aged 20 years are highly sensitive to wind gusts, proving a prime access point for water infiltration.

Dislodged Tiles

At the 20-year mark, multiple roof tiles are likely to become dislodged. Having an expert lock them in place is a simple way to prevent leaks.

Soaked Insulation

At this point, unattended leaks are already soaking your ceiling insulation, making it an excellent breeding ground for mould and rendering the insulation effectively useless.

Mouldy Insulation

If exposed to moisture, your ceiling insulation has heavily degraded and is likely full of mould. Degraded insulation is an excellent breeding ground for mould and could be promptly replaced to keep your indoor space healthy and comfortable.

Water Ingress

Unattended ridge caps with deteriorated pointing and bedding are a leading reason for water ingress and leaks coming through your ceiling.

Interior Damage

Any unattended leaks will show on your ceiling and walls as yellow stains and mould. An expert professionally treating your home for mould and water stains is costly…

Electrical Hazard

Unattended leaks are a significant electrical hazard and could be dripping onto electricals. If exposed to water, this poses a considerable fire risk and likely needs complete replacement.

Attic Damage

An unattended roof will likely allow multiple entry points for water ingress into your ceiling. Wood rot of your trusses could be a significant issue at this point, and the plaster of your ceiling may need complete replacement.
