Introduction. Due to global climate change, which has been particularly noticeable in recent years, emergency situations in the form of earthquakes, hurricanes, tornadoes, as well as manmade impacts, such as drone strikes, are increasingly occurring. In this case, the most negative impact is absorbed by the building's roofing, its upper part, including the cornice and parapet. All this is accompanied by serious destruction and material damage. In addition, a situation is possible when one destructive impact follows another. Scenarios for such situations are mainly considered for large energy facilities, including nuclear power plants. There are currently no specific recommendations for mass civil construction projects. In this regard, there is a need to search for solutions of complex protection that could be used these types of impacts.

Aim. Investigating the use of a "flexible upper floor" to protect building roofs from earthquakes, hurricanes, tornadoes, and drone strikes.

Materials and methods. To evaluate options for protecting the building's roof from natural and manmade impacts, technical literature, recommendations, and design standards were studied and analyzed.

Results. The proposed solution for the comprehensive protection of the building's roof involves a known design: a flexible upper floor that functions as a dynamic damper during earthquakes. This article examines known design solutions of dynamic dampers, highlighting their potential use in protecting buildings from extreme loads.

Discussion. Further research is required to justify the possibility of using a modified dynamic vibration damper in the form of a flexible upper floor as a comprehensive protection for the building roof.
