Dover Heights is a prestigious and dramatically positioned suburb perched on the clifftops above Sydney’s eastern coastline, and its exposed headland setting combined with established residential streets and native coastal vegetation creates some of the most demanding gutter maintenance conditions of any suburb in the eastern suburbs. The suburb is fully exposed to powerful southerly and onshore winds that hammer rooftops with salt-laden air, sand, and coastal debris from multiple directions, accelerating corrosion on guttering materials at a rate that is particularly pronounced on this exposed clifftop location. Heavy ocean storms hit Dover Heights with full force given its dramatic headland position, and with water sheeting off roof lines at pace during intense rainfall events, blocked gutters on these clifftop properties can cause serious and costly water damage that regular professional maintenance can entirely prevent.
