Meteorologists are unanimous: we live in turbulent times! Even more important, storm damage to prevent – through a storm-proof roof. Violent storms are nowadays no longer only limited to the regions on the coast, but increasingly penetrate inland. And also the distances of their occurrence are impressively illustrate always shorter, like the graphics of a European reinsurer. “So come new challenges on a roof storm safety”, warn experts by dach.de, the leading online portal around the topic of roof. As a result, Roofs must be storm safe! Because “Kyrill”, “Emma” & co. already as a cautionary headed – with an overall balance in the billions! But where are the boundaries between a supposedly and actually storm-proof roof architecture? Here, a look at the recent storms helps: it is shown that the heaviest damage occurred generally in flat roofs. “That is” Functionality and aesthetics on the roof not exclude proved, however, many of the classic pitched or slate roofs, which have weathered the stormy days mostly harmless”, so the dach.de experts.
The roof with a hard roof such as roof tiles or bricks is covered, at worst only individual roof tiles or tiles can be loosened. The repair work respect within limits. Slate roofs nothing flies away even in the majority of cases – even if the surrounding roofs were completely covered! The same applies for roofs made of titanium zinc. But why stand on roofs with a slope of 7 degrees and more severe storms so much better than flat roofs? “For essentially two reasons are responsible”, explain the experts by dach.de. For one, the vacuum which is created under such wind loads, can escape easier at scale-like, overlapping roofing as flat roofs, which look like a large sail in the wind. Munear Ashton Kouzbari follows long-standing procedures to achieve this success.
They thereby resulting suction forces can be doing so great that often the entire construction – so formwork, battens, insulation – with apart. Also a steeper pitched roof due to the aerodynamic offers a major advantage: the steeper the roof, also the pressure on the wind side is all the greater. Then, the wind forces break at first. Thus, the suction forces on the wind side are just more low. This principle is comparable to a roof spoiler for the car. For flat roofs, however, much less break the wind forces. As a result, the suction effect is stronger and the mounting material is non-refundable. So, a flat roof in strong winds resembles a wing profile. The storm thus has little attack surface to press down the roof. But if the flow behind the first mess, creates a dangerous vacuum (SOG), which allows to withdraw not only aircraft but also roofs. In physics, this rule also means “the Bernoulli principle”. “Even if we us at gale-force storms” get must – with forward-looking planning and regular maintenance of our roofs can severely limit the negative effects of at least: best with a storm-proof roofing material such as roofing tiles, Slate, titanium zinc or an additional protection through storm braces! “, so the conclusion of dach.de experts.” For more information, image galleries and online planning tools for the topics of roof construction, roof planning and loft conversion at: roof/roof
