Progressing climate change contributes to the occurrence of dangerous weather phenomena – strong winds or hurricanes – in our country. In today’s article, we consider the choice of a wind-resistant roof structure. Read on and find out more!
The probability of occurrence of dangerous phenomena related to gusty wind depends on the geographical location. In our country, the EN 1991-1-4: 2008 standard is used to evaluate the location in this respect, which divides Poland into 3 areas:
However, weather anomalies occur more and more frequently. Strong gusts of wind, typical of zone III, may occur practically all over Poland. That is why it is worth knowing how to strengthen the roof structure and what kind of roof structure will be wind resistant.
At the outset, we mention when the wind can break the roof off. Professionally designed and installed roof surface should survive blasts of min. 70 km/h. The wind blows the roofs off depends mainly on the solidity of the workmanship. The most dangerous for the roof structure are hurricane gusts of wind with a speed exceeding 120 km/h.
First of all, be aware that the most important aspects of resistance will be: the weight of the structure and solid assembly.
The heavy roof covering resists strong gusts of wind. However, it can not be forgotten that the assembly and maintenance of the roof also play a big role. Without a well-installed roofing material and its subsequent maintenance, even heavy roofing can not cope with storms.It is also worth remembering to secure and firmly attach the sensitive elements of the roof. It will be important to fasten the edge parts as well as the central part of the roof. An experienced roofer will surely pay attention to the necessity of firmly fastening the draft-sensitive elements in the area of the ridge, baskets, backs, corners, eaves, chimneys or windows.
Investors and homeowners often wonder about how to strengthen the roof structure. One of the ways is to solidify the roof by firmly fastening the wall plate. The roofer should use durable anchors made of galvanized steel – not susceptible to corrosion. It is also necessary to connect the trusses to each other, which will protect the ridge against strong winds.
