As more homeowners recognise the importance of insulating walls and floors, it’s easy to forget the area under your roof tiles. Yes, that often-overlooked space deserves just as much attention.
Wondering why you should insulate under your roof tiles? This guide reveals the pros of roof insulation and the best material for your tiled roof.
Benefits of Insulation Under Roof Tiles
So, why should you insulate under your roof tiles? Let’s count the reasons:
Lower Energy Bills
Uninsulated roofs can leach heat in winter like a leaky tap meaning that you probably have to overly rely on your heating to stay comfortable, burning a hole in your finances
Insulating under your roof tiles traps the energy within your home instead of letting it escape through the roof. As a result, you’ll be able to lower your energy consumption and experience lower heating bills.
Enhanced Comfort All Year Round
Say goodbye to biting winters and stifling summers. With proper roof insulation, your home becomes a cosy haven no matter the season, especially if you’re using your loft as a living space.
During chilly winters, roof insulation traps heat and creates a consistent indoor temperature. In the summer, roof insulation blocks the intense sun and prevents excessive heat from invading your living spaces. In both cases, your heating and air conditioning (if you have any) won’t have to work as hard.
What’s even better? A recent study shows that better insulation is a lifesaver. Proper roof insulation keeps homes warmer, which reduces exposure to indoor pollution, particularly when you have good ventilation. Meanwhile, a poorly insulated home exposes you to indoor pollution, which can worsen chronic heart and lung issues.
Prolonged Roof Lifespan
Your roof takes a beating from rain, snow, wind, and the harsh rays of the sun, and without insulation, it ages faster than it should. Why is this?
The constant assault by nature gradually weakens your roof’s defences. Sudden changes in temperature cause your roof to expand and contract rapidly. Over time, this can lead to cracks, fading, warping, and deterioration.
In short, insulation prevents unnecessary stress on your roof, extending its lifespan. You won’t have to fork out hefty sums for premature repairs or replacement.
Moisture is no friend to your home. Along with an adequate ventilation system, roof insulation regulates temperature and ensures the roof surface doesn’t hit the dew point, where condensation occurs.Reflective foil insulation, for instance, has a breathable membrane that can double as a vapour barrier.
Properly insulating under your roof tiles wards off moisture-related issues like dampness, rot, mould, and microbial growth. If left unchecked, these issues can eventually impact indoor air quality.
Positive Environmental Impact
We all want to do our bit for the environment, right? Investing in roof insulation isn’t just a win for your wallet in the long run; it’s also a positive stride towards a greener planet.
Keeping the energy inside your home contributes to energy conservation and reduces the overall power demand. It’s a simple way to make your home more energy-efficient, comfortable, and eco-friendly.
Choosing sustainable insulation materials takes your green efforts a step further. So, look for recycled options — they’re good for your home and the earth.
Better Property Value
Eco-conscious homebuyers are increasingly attracted to energy-efficient features. A well-insulated roof is a great sign that the home is designed for comfort without over-reliance on heating or cooling systems.
It’s a selling point that assures buyers that they’ll continue to benefit from lower utility expenses.
How to Insulate a Tiled Roof
Here’s a detailed guide to help you through the process of insulating your roof tiles:
Assess Your Roof Space
Look for signs of leaks or damage and clear your roof space of any stored items or debris. Ensure there’s a safe and secure area to work and repair damaged roof tiles before installing your insulation.
Choose the Right Insulation Material
Several insulation materials work well for tiled roofs. Consider these options:
- Mineral Wool: Excellent for thermal and acoustic insulation, mineral wool is easy to handle and install. It’s a cost-effective choice for many homeowners.
- Fibreglass: Lightweight and widely used, fibreglass is a good thermal insulator. It comes in rolls or batts, making it easy to fit between joists.
- Rigid Foam Boards: These boards are a solid option for insulating pitched roofs. Rigid foam insulation provides high thermal and moisture resistance.
- Spray Foam: It has the best R-value of all materials, meaning it’s most effective in resisting heat flow. Spray foam is applied as a liquid and expands to fill all gaps and crevices, creating a seamless and airtight barrier.
Each insulation material has its advantages, so choose based on factors like cost, ease of installation, and performance.
Measure the distance between your roof joists to determine the thickness of the insulation. The recommended depth for pitched roof insulation is typically around 270mm.
Then, calculate the total area to ensure you buy enough material to cover the entire space.
Install the Insulation
Start by rolling or placing the insulation material between the joists, and ensure a snug fit to prevent heat loss. Pay special attention to areas around chimneys, pipes, and electrical wiring.
Use offcuts of insulation material to fill voids and ensure a continuous layer of insulation. You can also apply expanding foam to seal cracks and tackle hard-to-reach gaps.
And don’t forget to maintain enough ventilation in your roof space to prevent condensation. Lastly, ensure that existing vents are not blocked by insulation.
Roof Insulation Conclusions
Roof insulation is a practical investment that pays off in numerous ways. It’s a long-lasting solution to those sky-high energy bills. Plus, it prevents your home from getting too cold in winter or overly hot in summer.
And while enjoying your cosy home, you’re also doing the planet a favour by leaving a smaller carbon footprint.
Frequently Asked Questions
How Much Does Tiled Roof Insulation Cost?
It’s not a one-size-fits-all answer. The expenses depend on factors such as the insulation material you choose and the size of your roof. Keep in mind that different materials and installation methods come with varying price points.
Fortunately, there are various energy grants and incentives available for home insulation. We can connect you with trusted installers in your area to get the most accurate costs for your roof insulation project, including the availability of any funding grants. This way, you can compare costs and choose the option that best fits your budget.
Can I Install the Roof Insulation Myself?
Of course, you can take on roof insulation by yourself if you have easy access to your roof space. But let’s be real, DIY projects can be a real time and energy drain, especially if you’re not exactly a pro at roof insulation.
Areas under the roof can be tricky to deal with, with beams, vents, wiring, and the height to think about. Proper roof installation also involves consideration for ventilation to avoid moisture buildup and mould growth.
Negotiating these challenging spaces requires expertise, particularly for spray foam insulation. Professional installation ensures the job gets done efficiently and saves you from potential headaches later on. It also frees you from the stress of potential DIY mishaps or oversights.
Rest assured, this upgrade guarantees solid results and lasting benefits for your home.
Does Tiled Roof Insulation Require Maintenance?
Like other parts of your roof, insulation isn’t immune to wear and tear. You should regularly check the condition of the insulation under your tiled roof to ensure your home stays comfortable and energy-efficient.
We recommend doing this check at least once a year to catch any potential damage or wear in your insulation early on.
If you have spray foam insulation, pay extra attention to ensure there are no signs of moisture. The nature of spray foam can sometimes hide visible signs of leaks, so routine inspections are an absolute must.
