Abstract

Due to various reasons, problematic spots where leakage may occur manifest on the surface of the eave and gutter components of roofs and on the joints between the components. Depending on their characteristics, wind and sunlight are climatic parameters that have a gradual impact in rendering various types of damage at these points. In this article, an observation-based investigation and evaluation was made of the wooden fiberboard-covered eaves of the roofs of a 28-building mass residential settlement in the district of Maslak, Istanbul, and constructed in 2007, to assess the effect of prevailing wind and solar radiation related various damages that had occurred over the 12-year life cycle of the residential complex. The impact ratios according to direction were assessed taking into consideration prevailing wind frequency and solar radiation amount. The results of the evaluation showed that the rupture and divergence defined as destructive damage in the veneer of the wooden fiberboard roof eaves changed in parallel with the forcefulness of the prevailing wind. In the directions where the effect of solar radiation was low, it was seen that due to delayed drying, the planks of wooden fiberboard displayed swelling, mossing, and cracked joints, and also damage in the form of deformations and ruptures.
