还有下面这些，有分就加上点吧~~
Colorbond屋顶，咱叫彩光板吧。很多人会说是铁皮屋顶，其实是有别的。现在很多新房子都选用它，价钱也会高些。买房之前没注意屋顶是什么材料的，等买了之后发现是coloebond材质的，在坛子里看很多人说下雨会很吵啊，白天会很热啥的。搬进来之前给我愁的呀，还听说之前的房主特意掀了瓦顶换成了colorbond顶。我想这房主怎么这么想不开呀。后来settle了搬了进来凑巧就碰上了雨季。第一宿晚上就大雨，我完全不知道，一点声都没听到，我想自己怎么睡得这么死？第二天白天又开始下雨，我沏了杯茶在客厅竖着耳头听，一点声没有，外面雨声能有，家里一片宁静。自此我彻底放心了。从搬进来到现在有过几次30度以上的天气，家里并不很热，跟我以前住过的瓦顶房没区别。当然还没遇到40度高温的检验。目前并不觉得需要安空调，再热些冷风机应该能搞定。我想这种房顶应该是会做很好的隔音隔热层吧？这个有木有我也不得而知。汇报完毕，总之大家以后看房遇到这种屋顶不用被困扰住了。
对大部分人来说，COLORBOND就是彩钢瓦，这是一个误解。COLORBOND是BLUESCOPE STEEL的专利涂层。只有是用BLUESCOPE出的彩钢板做出来的产品才能挂COLORBOND的品牌。不然的话，产品描述上只会说是PAINTED STEEL。大家如果买的是有COLORBOND标志的产品是记住要供应商提供由BLUESCOPE提供的10年 COLORBOND WARRANTY。如果提供不了，那就证明不是COLORBOND产品。
不是所有的钢瓦都是用COLORBOND涂层的。
metroll有一部分是用COLORBOND钢卷的，有些便宜的产品不是，要问明白供应商究竟是不是。
Stramit是不用COLORBOND钢卷的。
Lysaght是用的，因为Bluescope是它的母公司。（也是最贵的）
希望能让大家对COLORBOND有进一步的了解，LZ用不用钢瓦就见人见智了，得看户型和环境了。
我是专业做屋顶的，也简单来说说吧,COLORBOND 就是冷压喷塑的铁板，这是近些年用的比较普遍的一种屋顶，水槽，和有些室外的围墙的普遍用料。优点是美观，轻巧，外形多样，不用维护。前些年的铁皮屋顶和水槽用的都是镀锌铁板的（就是没有颜色，国内叫做白铁皮的那种），一般情况下寿命在30年以上。厂家给的guarantee一般是15年。这里就统称铁皮屋顶吧，铁皮屋顶一般在铁皮下面要铺一层，银色的纸，也就相当于保温棉。目的是防紫外线和防雨。
瓦顶，分为陶瓦和水泥瓦两种，现在有新出的塑料瓦，很薄是固定在框架上的，用的不是很普遍。陶瓦正常来说寿命要50年左右吧，（当然我说的是瓦不是说不需要重做水泥和清洗，）也要看具体情况。水泥瓦一般15年左右要考虑维护一下了，就是屋顶重做，目的是防止瓦风化。
从框架来说铁皮屋顶要比瓦顶的要轻，也就是说瓦顶可以改铁皮的，铁皮的不可以改成瓦顶的，当然非要改也可以，不过要花大价钱的。还要申请。两种的价格基本谈不到那个更贵，基本差不多吧。铁皮的下雨很响倒是事实，不知道大家注意过没有，如果开车去自驾游，就可以发现，小镇上的房子基本上铁皮的居多。就是为了减少维护。
再多的一时也想不出，有问题大家可以来问。谢谢了。
不要人云亦云。在现代技术突破的今天，必须接受新事物。colorbond不是一般的铁皮，也不是一般的彩钢，而是博思格钢铁具有最先进技术含量的涂层钢板。具有抗腐蚀高寿命，具有红外线反射冬暖夏凉特性，具有抗尘粘附功能，具有防噪音技术，是水泥瓦陶瓦所不能比拟的现代材料。其材料成本高于水泥瓦陶瓦，但人工铺设成本低。总体造价高于水泥瓦，低于陶瓦。
Over the years I've owned both and I'll never go back to tiles.
The reasons are :-
At house design stage there are far more options with a colorbond roof when you are not tied into a high pitch design, particularly multi level designs.
During construction there are big savings with the wall framing, lintel sizes, truss costs, purlin spacing and what you get is a solid braced roof structure.
Post construction, with colorbond you have a maintenance free roof (other than gutter cleaning). With a tiled roof, the maintenance is ongoing, particularly after large storms. You need to keep a good supply of spare tiles for such occasions.
Noise for me is not a problem. I have the blanket installed under the colorbond and quite like the muffled sound of the rain. During heavy storms, I much prefer the sound of the rain to the sound of broken tiles being thrown around the roof or the worry of not having checked the ridge cap pointing for some time.
Then there are other considerations like whether the roof is suppling your drinking water or if you are in a bush fire prone area.
I concur. Yes I am biased too. To me nothing better than a colorbond roof.
I would also add this challenge to supporters of tiled roofs. If you can safely climb a ladder to view each external corner and internal corner of guttering. On a fair proportion of tiled roofs you may likely find mortar blobs and tiles stuck in the guttering left behind by the roof tilers. Sadly a lot of guttering and downpipe systems have never worked from the day they were first built. I know what I think but would be interested to hear from those who have never looked before but are capable and can do it safely.
Straw poll result?
When choosing a roof for your new home, you’ll most likely be faced with a choice between the two most popular Australian roofing methods – traditional concrete tiles or corrugated metal roofing with a bonded paint finish, otherwise known as Colorbond or CB.
While concrete tiles have been used throughout Australia for over 75 years and remain the first choice for many homeowners, installations of Colorbond roofs has increased significantly in recent years. Originally developed in the USA, the technique of bonding paint to a galvanised base has undergone extensive refinements here in Australia to create a non-combustible roofing material. It also not only has outstanding resistance to corrosion, chipping, peeling, and cracking, but also offers an aesthetically pleasing solution for all kinds of roofs.
Concrete tiles and Colorbond both have their merits, and although sometimes it just comes down to personal preference, it’s important to understand the qualities of both materials in order to make an informed decision suitable for your particular home.
Taking a look at the aesthetics
There’s no doubt that concrete tile roofs continue to be a popular and cost-effective way of recreating the appearance of more expensive terracotta tiles. They’re available in a variety of colours to contrast or complement the rest of the building, and with the advent of new production techniques, you can either opt for a traditional look for your roof or something more modern.
Colorbond roofs are characterised by their clean lines, providing a crisp, modern look. Colorbond comes in a wide range of colours, suiting all kinds of locations and tastes, so aesthetically speaking, it’s all down to personal preference when it comes to choosing between the two roofing options.
A more lightweight option
One major advantage of using Colorbond over concrete tiles is the difference in weight. Colorbond is extremely lightweight, meaning that much lighter roof framing can be utilised and rafters can be spaced wider apart. Unlike concrete tiles, which tend to absorb a percentage of rainwater before it runs off, Colorbond roofing weighs the same whether it’s wet or dry. If you’re considering adding a traditional Australian verandah to your property, it’s advised that you choose Colorbond roofing, as it’s suitable for use with flat roofs, minor pitches, and steep pitches.
Resilience, weathering and thermal insulation
The Colorbond manufacturing process produces a material that is far more resilient and weather-resistant than traditional concrete tiles, thus requiring less money on maintenance. Colorbond can withstand pretty much anything the Australian weather can throw at it, and it’s also non-combustible. However, this resilience can be a disadvantage if you need to add a vent, flue, or air conditioning after the roof has been installed, as it’s extremely difficult to penetrate.
You’ll also find that Colorbond has exceptional thermal insulation qualities, meaning a possible reduction in energy costs, but you must ensure that there is adequate ventilation in the roof space to minimise the effects of condensation.
Looking at maintenance costs
It’s worth taking maintenance costs into account before making your decision. Concrete tiles are more fragile than corrugated metal, making them more prone to cracking and leakages. It’s also more common to experience ridge capping problems and leaf blockages with concrete tiles.
You should also factor in colour oxidation and deterioration, as concrete tiles can fade significantly within five years of installation. A Colorbond roof makes these problems practically disappear, with minimal maintenance required and colours staying true for many years.
Noise abatement
In the past, traditional corrugated metal roofing has meant that the sound of rainfall was amplified throughout the home. While this is true to some extent with Colorbond roofs, it’s possible to minimise the noise with the use of acoustic blankets, foil, and insulation. Many people enjoy listening to the pitter-patter of raindrops on their roof, and prefer to choose Colorbond for this very reason! However, if you feel this would be an issue for you, you may prefer a concrete tiled roof instead.
Benefits of metal roofs
Metal roofing provides plenty of advantages and is a popular choice – particularly for its longevity and curb appeal. Here are the top benefits of metal roofs:
Longevity: Metal roofs can last from anywhere between 40-70 years, depending on the type of material.
Durability: Metal roofs are able to withstand nearly any type of weather conditions including rain, wind, snow, hail, and heat. There are types of metal roofing that even come with fire resistance. Because of their sun reflective coatings, metal roofs also have improved insulation.
Easy to maintain: Metal roofs, especially Colorbond roofing material, comes with a 25-year warranty, as well as a flaking and chipping warranty of 12 years. In this time, you won’t need any maintenance at all, aside from the removal of any heavy dirt or grime which can be done with a hose and soap solution.
Energy-efficient: Metal roofs reflect solar heat, which can reduce cooling costs by 10-25%.
Environmentally friendly: Metal roofs have a recyclable content depending on the material used, and are also 100% recyclable at the end of their lifecycle.
The challenges of metal roofs
One of the biggest and only disadvantages of metal roofs is the cost. Although it’s off-set by its durability, metal roofing can be expensive to install, which may make it out of reach for some homeowners. Generally, metal roofing is as much as two to three times more expensive than other roofing materials. Other disadvantages include:
Noisiness: Although metal roofs are durable in all types of weather conditions, it can be very noisy during rain or hailstorms. To fix this, it’s possible to install soundproofing insulation, however, this is another added cost.
Performance: Sometimes metal roofing can trap rising moisture and turn to liquid as the roof cools during the night. This can result in damage and is more common if the roof or installation was installed improperly.
Colour matching: If in need of repair or in the case of a home extension, it may be difficult to find an exact colour match to the existing roof.
Benefits of tile roofs
The most common roof tiles used in Australia are cement/concrete tiles and terracotta. Both options provide a great, classic aesthetic to the home and come in a range of shapes and finishes. They are also ideal for the hotter Australian climate, or homes that have exposure to salt air. Other benefits of tile roofs include:
Longevity: A tile roof can last for up to 100 years and are known to withstand hail, high winds, and even fire. Most manufacturers provide a 50-year warranty with tile roofing. Tiles are also impervious to rot, rust and insect damage and will never decay.
Soundproofing: Unlike metal roofs, tile roofing has great sound insulation and acoustic performance.
Environmentally friendly: Tiles are derived from earth minerals and can be pulverized or recycled once removed or at the end of their lifecycle.
Energy-efficient: The heavy thermal mass of roof tiles helps to regulate temperatures indoors, providing excellent thermal insulation.
Disadvantages of tile roofs
While tile roofing has a reputation for being durable and long-lasting, there is a chance of breaking upon installation, as well as structural damage due to their heavy weight. Other challenges one might face with tile roofs include:
Difficult installation: Installing roof tiles requires professional roofers to measure, lay and check for any gaps or inconsistencies.
Need for ongoing maintenance: Although durable in the right conditions, tiles are brittle. Clay, slate and concrete tiles can break if they suffer a heavy impact such as a falling tree, or being walked on. Extreme weather and shifts in a home’s foundation may even cause tiles to shift, resulting in roof leaks. Because of this, tile roofing will need regular maintenance and repairs.
High costs: Depending on the material of tile used, installation can be costly. Usually, concrete tiles are the most cost-effective, with slate tiles the more expensive option.
Taking cost into consideration
Finally, if the cost is the most important factor in your decision, then you’ll find that concrete tiles can be more cost-effective to install. However, when factoring in the costs of future maintenance, it will be higher for concrete tiles than Colorbond roofing. So again, while the roofing materials have their own similarities and differences, it all comes down to personal preference when choosing between the two.
Doing your research before making a decision
It is important to seek out a quote from an experienced home building specialist and provide details of your project for the best possible solution for your renovation project.
