Don’t be fooled!

Hardly anyone would deliberately choose to build or renovate a roof for their house that wouldn’t last. However, a lack of knowledge or cutting corners in the wrong places means that repairs to the roof are required after just a few years.

Roofing sheets have long come with a guarantee against corrosion, but single-coat painted roofing screws that have been in use have had to be replaced due to rust and roof leaks, even though the roof itself was otherwise in good condition. Now, however, a durable roofing screw has been successfully developed for which a guarantee equivalent to that of the roofing sheet itself can be provided. The innovative design and patented three-layer coating of the Finnish-made KINGI® roofing screw ensure that the roofing screw is no longer the weak point of a metal roof.

Kingi Oy’s automated coating line enables cost-effective production. This means that everyone has the opportunity to install a durable roof on their home whilst saving both the environment and financial resources.

By investing just 100 euros* more in durable roofing screws during installation, the homeowner gets a metal roof where even the screws are guaranteed not to rust for the next 20 years. In other words, for a very small additional cost, you can completely avoid the hassle of cheap, rust-prone screws and the repair work they cause, which ends up costing many times more. The extra cost for years of peace of mind is really small compared to the total cost of a metal roof, which, taking materials and installation into account, is around 12,000 euros.

The best roof is also the most trouble-free.

*The price calculation is based on an average roof size of 150 m². For the installation of roof sheets, including valley and ridge sheets, 8–10 screws per square metre are used. This equates to 1,200–1,500 roofing screws. Based on the recommended retail price of the KINGI® roofing screw at €43.42 per 250 pieces, the cost of the screws for the example roof comes to €178.80 – 223.50, which is on average only 100 euros more than single-coat painted screws
