Metal roofing is a popular choice for both modern and traditional buildings due to its durability, aesthetic appearance and low weight. One of the key factors that plays a role when choosing a roofing material is its durability. How long your metal roof will last depends on a number of aspects - from the quality of the material to the method of installation and maintenance.
How long does a metal roof last?
Modern metal roofs have a lifespan of 30 to 70 years, in some cases even longer. This wide range depends on several factors:
1. Type of metal
- Galvanized metal: The usual lifespan is 30-50 years, provided that the surface is of high quality.
- Aluminum metal: It can last 50 years or more due to the natural resistance of aluminum to corrosion.
- Copper metal: It is one of the most durable materials, its lifespan can exceed 100 years.
2. Surface treatment
- High-quality protective layers such as polyester, polyurethane or PVDF significantly increase resistance to weathering, UV radiation and corrosion.
3. Climatic conditions
- In areas with extreme weather conditions such as strong winds, hail or high humidity, the lifespan of the sheet metal may be slightly shorter if it is not treated properly.
4. Installation and maintenance
- Professional installation minimizes the risk of mechanical damage and ensures that the joints are tight. Regular maintenance such as cleaning the roof and checking the seals extends its lifespan.
What affects the lifespan of a sheet metal roof?
1. Material quality
- Cheaper coverings with a smaller thickness or lower quality surface treatment have a shorter lifespan and may be more susceptible to damage.
2. Installation method
- Incorrect installation, such as unsuitable screws or poor joint sealing, can lead to water leaks and premature corrosion.
3. Roof maintenance
Although metal roofing requires minimal maintenance, it is recommended to:
- Regularly clean the roof from dirt and leaves.
- Check the surface of the roofing for damage, scratches and peeling coating.
- Remove snow if necessary, especially on flat or less sloping roofs.
How to extend the life of metal roofing?
- The right choice of material: Invest in a quality roofing with sufficient sheet thickness (ideally 0.50 mm or more).
- Professional installation: Ensure that the installation is carried out by an experienced professional.
- Regular inspection: Carry out visual inspections of the roof at least once a year.
- Surface renewal: If the surface of the roofing shows signs of wear, have it treated or repainted.
Conclusion
Metal roofing is a long-term and reliable investment. Their lifespan can easily exceed several decades if you choose quality material, ensure professional installation and give them basic care.
