Condensation should be a primary concern with any type of roofing, including tile since it can occur with any style of roof, home or building, especially during the colder months of the year, unless proper measures are taken. Moisture is the main cause of this issue, and it happens when the heated air inside the building rises up into the attic or roof area. This is where the warm air comes into contact with the cooler exterior air to form the condensation. When the roof is not designed correctly, the moisture has no escape route and can cause major issues. We provide further facts about the problem of condensation, and how to avoid it in the following.
Damage That Roof Condensation Causes
• Excessive condensation in your roof’s structure encourages mould growth. Mould can spread throughout the area rapidly since it prefers a moist environment to a dry one. When you do not address this issue fast enough, it can affect other parts of your home or building, and the health of everyone who frequents it. In addition, mould has been known to feed on the organic materials in homes and buildings.
• In addition to mould growth, roof condensation can cause the structural components of the roof to rot. Wood beams and other parts can start to decay while steel or metal parts can corrode and weaken. As a result, the integrity of your house’s or building’s framework will decrease drastically.
How to Prevent Roof Condensation
• The first way to prevent moisture from accumulating enough to cause condensation is to hire a reputable, experienced roofing company to install your tile roofing. It will know the specific setup that your roof requires to prevent this issue.
• Adequate roof ventilation is a must to allow the moisture a route to escape from your home and building. An experienced roofing crew knows how to add just the right amount of ventilation without going overboard. Excessive venting can cause heat loss, which increases your heating costs.
• While insulating your house or building in a quality fashion can cut down on condensation, go one step further and have the roofing crew install a vapour barrier. A vapour barrier is a waterproof membrane that moisture cannot penetrate.
As you can see, roof condensation can be a major concern with of roofing materials, including tile roofing, since it is a structural and design issue more than it has to do with the nature of the roofing.

Roof sarking is a flexible laminated membrane for use under roofing for tiles for added protection to the roof’s structural components. It is applied at the time of the roof installation prior to setting the tiles into place. It depends upon the size of your roof as to whether Australian building codes mandate the use of sarking. We provide you further explanation of what sarking is, when to install it and the benefits of having it as part of your roofing system in the following details.
What Is Sarking?
Sarking is a flexible membrane that contains various materials, such as polystyrene, reflective foil or felt, depending upon the brand of it. If it contains foil, though, it can reflect heat as well as perform its other functions. Sarking acts as a second, protective skin for the roof under the roofing tiles and helps prevent rain and other elements from penetrating into the sheathing and beyond. Also, it can shield the interior of the building from dust invasion during draught. On top of this, it can increase the thermal performance of the roof.
When to Use Sarking?
The Building Code of Australia or BCA mandates that sarking is necessary for any new residential roofs that contain rafters longer than six metres. Also, it is recommended that any tile roof with a pitch lower than 20 degrees should contain sarking. Today, though, many roofers offer sarking with all of their roofs, regardless of the size of it for extra moisture protection and other benefits. Refer to the next section for more information on the benefits of using roof sarking with your roofing tiles.
The Benefits of Installing Sarking
• Sarking provides storm protection for roofs and even can help channel rain runoff into the gutters
• Roof sarking will act as a dust barrier, especially in times of draught
• A layer of sarking protects the roof cavity
• Roof sarking offers superior moisture resistance to roofs since it prevents water from seeping into the sheathing
• Increase your tile roof’s thermal performance by adding sarking to it
• Roof sarking provides protection from bushfires, and therefore, is ideal for homes in bushfire-prone areas
