The cost of the Decra® roof depends on location and the complexity of your roof’s design. But remember you will always need to calculate the pricetag of a roof as a whole. Including accessories, installation etc., and make your calculations based on the long term service life of your roof. You may pay a bit more now, but you will reap the benefits later. You will not need to replace your Decra® roof after only one or two decades, as in the case of some other, cheap rooftiles.
Re-roofing has additional costs, such as the reinforcing or removal and disposal of the old roof in case you purchase heavy clay or concrete tiles. Since Decra® can even be up to 7-times lighter than those, you may be able to use your current roof structure. If you live in a coastal or high-wind location, a Decra® roof is likely to be less expensive than any other type of roof, because it won’t require special materials or fastenings to cope with extreme conditions.
Given that all products are anchored together in place, and they are also mechanically nailed into place in the support structure with 8 (!) nails per tile, the system will definitely not be blown away. The Decra® roofing systems have been specially developed to withstand the most extreme weather conditions and this has been proven worldwide over many years. Decra® is one of the safest roofing solutions on the market today.
Light weight Decra® tiles can be placed right on top of your current asphalt shingle or fiber cement roof. Only a professional assessment is needed and new battens to fasten Decra® tiles onto.
Decra® is remarkably resistant to damage from hailstones of up to 30 mm. Even a massive hailstone as large as 90 mm cannot penetrate through stone-coated steel. You will not need to be afraid of leakages or of replacing your tiles after a hailstorm if you have a Decra® roof!
It definitely will not. All Decra® products are made of a tried and tested material called ZM250; i.e zinc-magnesium protection with 250g of coating per sqm. ZM250 is a special steel coated with an alloy of 93.5 % zinc, 3.5 % aluminium and 3 % magnesium. The excellent corrosion resistance of ZM250 is attributable to the properties of the three components: on the surface of the cladding, aluminium and magnesium function as a barrier against corrosive substances and the zinc protects the steel via the “sacrificial effect”. Thanks to its 3% magnesium content, ZM250 steel offers self-healing on cut edges.
Decra’s basecoat bonds the stone granules to the surface of the tile for the lifetime of the tile. However, a small loss of chips at the edge of the tile during the installation process is normal, as these are not meant to stay on the tile.
Decra’s customers report a reduction in energy costs. Because a metal roof can reflect much of the solar radiation. Furthermore, metal roofs re-emit most of the solar radiation absorbed.
Yes. Weight should be placed directly over the batten when walking on the roof. However, we do not recommend walking on Decra® painted roof tiles, unless it is absolutely necessary and only for professionals equipped with the required safety kits, as the high gloss surface is slippery, especially when wet.
Decra® roof is no more susceptible to a lightning strike than any other roofing material. It only depends on the height and location of the building.
Their long lifespan means that you will not have to replace Decra® products for decades to come, which results in a lower burden on the environment as no new roofing work is needed. The products are also made of steel that can be recycled in the same way as steel cans or vehicle parts. Thanks to the lightweight, compact dimensions and safe packaging, the transportation of Decra® costs up to eight times less than clay or concrete tiles.
Yes. Decra® roofs have been independently tested and the ’run-off’ meets World Health Organisation guidelines for drinking water. Why is this relevant for? If your house is located in a remote area without a water supply, you will be able to collect the water that drains off the roof and use it for drinking water.
