Roof sarking is a protective layer installed under the roof tiles or shingles of a building. It is designed to provide additional insulation, prevent heat loss, and protect the roof structure from damage. Not to be confused with roof insulation (please read this article for a quick comparison).
Despite its many benefits, roof sarking, like every other aspect of your roof, is subject to developing issues that can impact the overall performance of your roofing system. Here are some of the most common roof sarking issues to look out for:
- Moisture buildup: Moisture buildup can cause the sarking material to become damp and deteriorate over time. This can lead to mould growth, which is never a good thing – as it can impact the air quality of the building and cause structural damage. To prevent moisture buildup, it’s important to ensure that the roof is properly ventilated and that the roof sarking is installed correctly.
- Poor installation: If the material is not installed properly this can lead to an almost-unlimited amount of issues from the get-go (depending on how bad the installation is). However even in the least severe cases of improper installation, overtime your sarking can become damaged or start shifting leadings to gaps and holes. This allows moisture and heat to escape – and nullifies the impact of your sarking solution.
- Age-related wear and tear: Over time, roof sarking can become worn and brittle, which can cause it to become damaged or even in the worst case – break. This can lead to moisture and heat loss, as well as increased risk of damage to the roof structure. To counter this, annual inspection and maintenance is recommended to help identify and repair any signs of wear and tear before they become a major issue.
- Pests: Pests such as rodents and birds can cause damage to the roof sarking, especially if it is made from a soft material like fiberglass. This can put your sarking and roofing structural integrity at risk. To prevent pest damage, it’s important to install a barrier between the roof sarking and the roof deck, and to keep the roof free of debris that can provide a habitat for pests.
- Fire damage: Roof sarking can also be damaged by fire, which can cause it to become charred, brittle, and damaged. To prevent fire damage, it’s important to ensure that the roof is properly ventilated and that any fire hazards, such as electrical wiring and appliances, are properly installed and maintained.
- Chemical exposure: Some roof sarking materials can be damaged by exposure to chemicals, such as cleaning agents, solvents, and chemicals used for roof maintenance. It’s important to ensure that any chemicals used in the roofing area are compatible with the roof sarking material and to follow manufacturer guidelines for proper use and storage of chemicals.
Roof sarking, just like every other aspect of your roof, has its many benefits and issues that you must be on the lookout for. If you are suspicious your roof sarking could be facing any of the above issues, then please contact our team today for a custom quote & inspection.
