Insulating your roof space is one of the most cost-effective ways to improve comfort, reduce heating and cooling bills and manage indoor temperatures year-round. In Australian homes, insulation helps prevent unwanted heat in summer and retain warmth in cooler months. Oz-Roof+2YourHome+2
2. How do I know if my insulation needs replacing or upgrading?
Here are some clear signs:
Insulation is compressed, sagging, missing or damaged (for example by pests or moisture)
You constantly feel the roof space is too hot or too cold despite using air-conditioning or fans
Your energy bills are increasing without other obvious causes
Your home is older and may have insulation installed below current standards If you’re unsure, we offer a professional inspection to assess the condition and suitability of your insulation.
3. What R-value or insulation standard should I aim for?
In Western Australia, the effective insulation value depends on your roof type, house design and the local climate. As a general guide:
The higher the R-value, the better the insulation’s resistance to heat flow. YourHome
It’s not just the insulation product but the total roof/ceiling assembly and installation quality that matter.
We’ll inspect your roof space and make a recommendation tailored to your home, ensuring compliance with applicable standards.
4. How long does insulation last?
Quality roof-space insulation, when correctly installed and maintained, can last many years. However, its performance can decline due to:
Compaction from foot traffic or stored items
Moisture intrusion, pest/rodent damage or contamination
Improper installation (e.g., gaps, poor coverage) We include a condition check as part of our service to advise on whether a replacement or upgrade is needed.
5. Can I add insulation over existing insulation?
In many cases yes — but it depends on the current condition:
If the existing insulation is undamaged, dry, and correctly installed, topping up may be viable.
If the old insulation is contaminated, rodent-ridden, wet or compressed then full removal and replacement may deliver better performance and long-term value. We’ll inspect and provide the best recommendation for your specific roof space.
6. What materials do you use and are they safe?
We use high-performance insulation materials that are compliant with Australian standards (such as AS/NZS 4859) and selected for suitability in WA climate conditions. YourHome All materials are installed safely, following manufacturer guidelines and industry best practice.
7. How much does roof insulation cost?
Costs vary based on home size, roof complexity, access, insulation type, removal of existing insulation, and any remedial works (e.g., pest proofing). We give all clients a no-obligation written quote after the inspection, so you can see exactly what’s included.
8. Do you need to access my roof space / what preparations should I make?
Yes — we’ll need safe access to the roof space and clear any stored items if required. To prepare:
Ensure roof access hatch is unlocked and unobstructed for the quote process only
Remove or relocate items stored in the roof space (for safety and access)
Clear pets and children from roof-space access areas during work We’ll provide a work schedule and safety guidance ahead of time.
9. Will the work create a mess or disruption?
We aim to minimise disruption:
Old insulation removal (if required) is managed carefully and clean-up is included
We use protective sheets where needed and ensure work zones are safely secured
After installation, we leave the area clean, tidy and ready for your use Our goal is a seamless process from inspection to completion.
10. Do you offer warranties or performance guarantees?
Yes. We stand behind our workmanship and the materials we install. We’ll provide details of the product warranties and any workmanship guarantee as part of your quote. We also provide advice on maintaining performance (ventilation, pest prevention, avoiding compression of insulation etc).
11. How soon can you schedule the inspection and installation?
We aim to be responsive. After you contact us by phone (0410 252 282) or via our website, we’ll schedule an inspection at a convenient time, and then book installation once the quote is approved. Lead-times depend on current demand, roof complexity, and supply of materials — we’ll communicate clearly so you know what to expect.
12. Is there any benefit in doing insulation at the same time as other roof / ceiling upgrades?
Absolutely. If you’re considering roof maintenance, ventilation upgrades, pest proofing, or roof restoration, bundling these works can reduce overall disruption and help ensure systems (insulation, ventilation, roofing) work together optimally.

OUR CLIENT TESTIMONIALS
“I found these guys after reading a forum about insulation removal. They were the most recommended company on the forum because of there honesty, integrity and workmanship. I can now add that I 100% agree with what others said about Megatec roof insulation solutions.”
Frank - Yanchep
“My partner and I spend hours researching insulation removal companies that can also deal with possums and rodent issues and were 100% satisfied that we chose the right one. Thanks Chantal, Dan and the crew for your thorough service. We needed the 400 square meter soiled “blow in” insulation to be sucked out within a couple of days before roof renovations. Was no problem for these guys. They were quick and tidy leaving no mess. Even having Colin come over and have a business minded chat was great. All the best with the new venture” .
Gerry G.- Wanneroo
“Was very happy with the services I received from Megatec roof Insulation. They were fast, affordable and more importantly efficient. Dan and Tanner explained the process, including the possum proofing and gutter guard installation, what to expect from the new insulation and the performance is everything they said it would be. We will recommend MRIS to anyone”.
Rebecca R.- Dawesville
“I highly recommend Megatec Roof Insulation solutions, I had them remove the old messy batts, vacuum the attic and install new hypogenic batts, and they did an excellent job, they did everything in one day and were reasonably priced. From the booking with Chantal and Dan and his crew was easy to work with, if u want insulation ring them for a quote first. Great job mate.”
Julia M. - Inglewood
“The Best experience I’ve ever had with a tradesman. Honest, reliable, competitive pricing. Dan has helped me with my own personal issues regarding dodgy work from tradesmen in the past, even fixed a leaking roof section. His honesty and service was second to none and am more than willing to recommend MRIS as a fair dinkum business.”
Grace Davies - Westminster
“After a fantastic job and compliments from my ceiling fixer, electrician and air condition guy I had to jump on board and say that Megatec Insulation Solutions did a very professional job.”
David Watson - Merriwa
“Many thanks to Dan and his crew for the excellent and extremely cost-effective removal of old stinky formaldehyde insulation and installing new of Bradfords Gold batts R4.1 the other day. Definitely a lot better than the $7,500 quote I received from some other installer, which I promptly consigned to the rubbish bin. They were on time and done in a day as promised. The difference is not unnoticed. House feels cosy again. Im getting them back to do the same to my rental in Freo and I know that they will do another superb job. Peace of mind guaranteed. Thanks MRIS.”
Sue - Waikiki
“I was reluctant at first to remove my old blown-in insulation because I read on the Internet that some companies charge $6000+. These guys did the job much cheaper and overall I was happy with the end result.”
Angela - Mindarie
“Thanks to Tanner & crew, thanks for the efficient and no hassle job you did removing the old Wool and installing the new Bradfords batts. We liked that Dan is truly knowledgeable regarding the pest problem and the insulation. Thanks for spending the time going through all the pros and cons of all the different insulation types. Thanks for getting rid of the rats in the roof, my wife can sleep in peace now.”
Sylvan - Huntingdale
“Megatec roof insulation solutions was great to deal with. I recently had the cellulose vacuumed/ removed and new batts replaced in my roof. The house is already cooler! Dan was quick to respond, was on time, spend time assessing the roof work, quote and came in under half of the other ridiculous quotes I received! I work away however, organising the job was completely hassle free. Tanner the crew lead even went as far as to remove some extra insulation that was over the garage, free of charge. Highly recommend these guys. Reliable, efficient, tidy and reasonably priced. All the things we need and expect in a tradesman! ”
Claire, Parthi and family
“Employing the services of MRIS was the best thing we ever did. Not only has the new insulation made such a positive impact on our home, but I cannot speak highly enough of the service that they provided. They were punctual, reliable and honest which are qualities many companies lack these days. They gave us an excellent price, quality service and Dan and his staff worked extremely hard to finish the job in incredible heat. I can also say the possums has also not come back after the possum proofing they did. I cannot recommend them highly enough.”
Megan Bell- Tapping
“Megatec Insulation are an excellent example of a business which show true professionalism in the trade industry. Not only did MRIS show up on time, quote a competitive price, communicate the entire process of insulation removal & install works to me, but were also highly informative, honest and did a fantastic job. We had our old cellulose insulation removed and installed Bradfords insulation which was recommended. I noticed the difference straight away and have since avoided running our A/C all day. Initially we were running our a/c for 8 hrs during the day with the old blown in insulation but now only run it for 1hr. I have since climbed into my roof cavity to store a few household items and am always impressed at how neat the insulation was installed. can’t recommend these guys enough.”
