Roof repair in Croatia applying modern technologies

Extensive repair works on collective housing buildings need to be undertaken in Croatia, a Central European transition country. The adjustment of national building codes to the market economic management of residential buildings is being speeded up. The results of the cost analysis show that the largest share of the investments can be expected for the repair of roofs (flat and mildly pitched), since their quality currently does not meet the ISO and EN standars requirements. It is concluded that the scientific knowledge and available state-of-the-art technologies and materials are not sufficient guarantee for the establishment of an integral quality management and control system in the repair project without the dedicated involvement of all relevant factors. Furthermore, the paper discussed the personal expirience of the authors, as designers, supervisors and contractors, acquired on roof repair works in Croatia.
