With years of industry experience, our team has expertly handled countless roof insulation projects across Launceston, Hobart, Devonport, and North-West Tasmania.

With the cost of energy constantly rising, insulating your home’s ceiling is crucial if you want to avoid paying excess on wasted energy bills. The Australian government estimates a huge portion of a home’s heat gains in summer (25% to 35%) and heat losses in winter occur through the ceiling. This range is higher than any other section of your home, making your home’s roof the biggest contributor to energy losses. Tasmania is one of the coldest regions in Australia, making proper insulation essential to prevent spikes in energy bills.

The Climate Council’s Smarter Energy Use report estimates that families in Tasmania could be losing over $400 annually in energy costs due to inadequate ceiling insulation. In addition to managing unnecessary financial pressure, living in a cold home can lead to health issues, making insulation not just a comfort matter, but an important health priority too.

Save on Energy, Keep Your Home Comfortable Year-Round

Insulation helps your living space maintain a comfortable, temperate environment year-round. It works by reducing the rate at which heat flows in and out of your house, giving you, as a homeowner, more control of your living space.

In winter, insulation traps heat generated inside your living space, keeping your home warm and cosy. Conversely, in the summer, it slows down the heat transfer from the outside environment to your home, helping you stay cool and temperate in the hotter months.

In addition, effective insulation can also dampen external noise, contributing to a quieter indoor environment. By installing proper insulation, you save money on energy bills and enhance your space’s overall comfort and livability.

Will Insulation Turn my Home Into a Hotbox in the Summer?

A common misconception about insulation is that it might make homes excessively hot during summer (the Hot Box myth). If installed correctly by an expert, quality insulation not only prevents heat from escaping in the winter but also slows down the rate of heat gain in the summer, maintaining a comfortable, moderate temperature inside your home year-round.

Insulation is a barrier to heat flow, making it effective in hot and cold conditions. This also means that quality insulation will help you maximise the cooling capacity of your air conditioning unit during the summer by keeping your home cool. Insulating your ceiling is one of the best places to start if you’re looking to achieve a balanced and pleasant indoor environment (regardless of the season).

Insulation Does More Than Just Lower Your Utility Bills

In addition to potentially hundreds of dollars in energy energy savings per year, insulating your ceiling has a range of important benefits:

Comfortable Living Environment

A constantly deviating internal temperature is a telltale sign your home’s insulation is not doing the job. Having a professional roofer install your insulation can help you maintain a stable indoor climate, keeping your home temperate and comfortable year-round. In addition, this also removes the inconvenience of continuous heating or cooling adjustments.

Noise Reduction

In select instances, insulation can minimise noise pollution and reverberation. If external sounds like traffic or internal echo are an irritation, roof and ceiling insulation can act as a sound buffer. By reducing the intrusion of outside noise and minimising echo, insulation helps create a quieter, more peaceful environment in your home.

Prevents Moisture Issues

Moisture and condensation in your home can lead to mould and mildew growth, posing health risks and eventually damaging your property. Roof and ceiling insulation can help prevent these issues by reducing condensation build-up. By maintaining a consistent internal temperature, insulation minimises the conditions that allow for moisture build-up, ensuring a healthier, mould-free living space.

Reduced Carbon Emissions

If you’re worried about your home’s environmental footprint, insulating your roof and ceiling can be a part of the solution. By minimising wasted heating and cooling costs, you can also reduce your energy consumption and ultimately reduce your home’s CO2 emissions. In addition, modern-day insulation products are eco-friendly, with manufacturing practices designed to minimise the environmental impact of production.

Improved Health

Living in a home that’s too cold in winter or hot in summer can negatively impact your health and well-being. Inadequate temperature control leads to discomfort and can exacerbate health issues like respiratory problems, allergies, and stress. Cold, damp conditions are particularly conducive to the growth of mould and mildew, which can have serious health implications, especially for those with asthma or weakened immune systems. Insulating your roof and ceiling creates a living environment with stable and comfortable temperatures, minimising stress and improving your overall health and well-being.

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.
