What Can Cause Premature Wear of Concrete Roof Tiles?
Understanding Premature Wear of Concrete Roof Tiles
Concrete roof tiles have become a popular choice for many Auckland homeowners because of their durability and aesthetic appeal. However, like any roofing material, they can show signs of premature wear if not correctly installed, maintained, or when exposed to particular environmental conditions.
Causes of Premature Wear
- Improper Installation: One of the chief culprits behind the premature wear of concrete tiles is incorrect installation. Ensuring tiles are securely fastened and adequately spaced prevents issues down the road.
- Environmental Factors: In suburbs like Parnell, which might experience more exposure to sea salt from the nearby coast, concrete roof tiles
- can corrode faster. The combination of sea salt and rain can slowly erode the tile’s surface.
- Organic Growth: Moss, lichen, and algae love the damp Auckland climate, especially in areas like Henderson. Their growth on tiles can trap moisture, leading to damage over time.
- Foot Traffic: Walking on tiles can cause breakage or micro-cracks, which, over time, can result in tile failure.
- Underlying Material Degradation: If the underlayment or battens supporting the concrete tiles deteriorate, the tiles can become unstable and get damaged.
Environmental Considerations
Concrete tiles, generally speaking, have an environmentally friendly profile. They’re energy-efficient and can be recycled. However, if they wear out prematurely, their eco-friendly advantages diminish, as replacing them often incurs additional energy and resources.
Pricing and Installation Costs
- Standard Concrete Tiles: These cost around NZD 84 per square meter. They are sturdy and have a basic design.
- High-end or Customised Tiles: With a price tag of NZD 168 per square meter, these tiles often come with enhanced designs, textures, or colours.
- Installation: On average, you can expect to pay NZD 112-154 per square meter for installation, depending on the complexity of the roof and any additional requirements.
Health and Safety Requirements
When installing concrete tiles, specific health and safety measures must be taken. Falling hazards are a primary concern, and workers are often required to use harnesses or other fall-protection devices. Proper scaffolding is also essential, especially in houses that have multiple stories.
Auckland Council Bylaw Requirements
Auckland has specific building codes that pertain to roofing materials and their installation. For instance, certain suburbs, due to their historical significance or environmental sensitivity, may have restrictions on roofing alterations or materials. Regional councils like the Waitematā Local Board or the Whau Local Board might have specific codes, especially concerning stormwater management. Always ensure you’re up-to-date with the latest regulations and get the necessary consents before starting any major roofing project.
Cost Breakdown Summary Table
| Item | Cost (per square meter) |
| Standard Concrete Tiles | NZD 84 |
| High-end/Customised Tiles | NZD 168 |
| Installation | NZD 112-154 |
In conclusion, while concrete roof tiles are a fantastic choice for many Auckland homes, understanding the potential causes of premature wear can help homeowners make informed decisions about installation, maintenance, and care. Ensure that you are abreast of all local regulations and safety requirements before undertaking any significant roofing project.
Frequently Asked Questions
What are the main factors leading to premature wear of concrete roof tiles? Improper installation, environmental factors like sea salt and rain, organic growth such as moss and algae, foot traffic, and degradation of underlying materials are key contributors.
How do environmental conditions in Auckland impact concrete roof tiles? The damp Auckland climate, particularly in areas like Henderson, can encourage the growth of moss, lichen, and algae. Suburbs closer to the coast, like Parnell, might see faster tile erosion due to sea salt exposure.
How do concrete roof tiles fare in terms of environmental friendliness? Concrete tiles are energy-efficient and recyclable. However, their environmental benefits diminish if they undergo premature wear, necessitating frequent replacements.
What’s the average cost for standard and high-end concrete roof tiles in Auckland? Standard tiles cost around NZD 84 per square meter, while high-end or customised tiles are about NZD 168 per square meter.
Are there specific Auckland council regulations I should be aware of before installing concrete roof tiles? Yes, Auckland has building codes related to roofing materials and their installation. Some suburbs might have material restrictions due to their historical or environmental significance. Always check with local boards, such as the Waitematā or Whau Local Board, for specific guidelines and obtain the necessary consents.
