Installing Zinc Roofing Yourself? Here Are Tips to Prevent Leaks!

Zinc roofing is often chosen because of its affordability and relatively easy installation. However, without proper techniques, zinc installation can actually cause problems such as leaks or premature damage.

If you plan to install zinc yourself on your home or warehouse, here are some important tips to ensure a long-lasting, leak-free roof.

1. Choose the Right Type of Zinc
Before you begin, make sure you choose the right quality zinc for your needs. Some types of zinc roofing on the market include:

Corrugated zinc: Commonly used for homes and warehouses.

Galvalume zinc: Rust-resistant, suitable for humid areas or coastal areas.

Color-coated zinc: More aesthetically pleasing and weather-resistant.

2. Pay Attention to the Roof Slope
Ideally, a zinc roof should have a minimum slope of 15 degrees to allow rainwater to drain smoothly. A slope that is too shallow can cause water to pool, which over time can lead to leaks.

3. Use Special Roofing Screws
Avoid using regular nails. Use roofing screws equipped with rubber washers. This washer serves to close the gaps in the screws to prevent water from seeping in.

4. Overlapping Installation
Ensure each sheet of zinc is installed with sufficient overlap—at least one wave to the side and 15–20 cm down. This is important to prevent water from entering through the gaps between the sheets.

5. Avoid Drilling Holes in Low Areas of the Zinc
When drilling or screwing, do so at the top of the wave, not the bottom. This prevents water from pooling and entering through the screw holes.

6. Check the Supporting Frame
Ensure the roof frame (such as a CNP frame or lightweight steel frame) is sturdy and level, so the zinc doesn't shift or warp easily when exposed to wind and rain.

7. Add Gutters & Fascias
To prevent rainwater from overflowing onto walls or terraces, don't forget to add gutters and fascias. This also helps extend the roof's lifespan and maintains the building's appearance.

Conclusion
Installing a zinc roof yourself can be a cost-effective solution, as long as it's done carefully and follows technical guidelines. With proper preparation, your zinc roof can be durable, strong, and leak-free.
