Flashings, Valleys and Gutters on Slate Roofs in Hobart

Where roof slopes meet other slopes or vertical elements (such as parapets and chimneys) flashings, gutters and cappings are required. The most critical areas of a roof are box gutters, because their failure will allow large volumes of water inside the building. Lead was traditionally used for flashings to both slate and tiled roofs. Check that flashings and cappings are firmly in position and are not cracked, corroded or perished.

Who may do the work

This site does not say who may fit flashings or gutters in Tasmania, because the pages read for it do not say. Ask whoever quotes what qualifies them for the work and what the quote covers.

Ask the provider what the quote assumes about the existing valleys and box gutters, and what the flashings are made of.
