Thomson Slate Roofing

Here, a galvnized slate hook is installed. Some installers will use a stainless steel hook. We find that the stainless will remain shiny and catch the sun, resulting in an easily visible slate repair. The galvanized hooks will actually turn a dull gray and blend into the roof while at the same time, lasting for many years. Copper hooks have also been available, but they can be too soft to nail into old sheathing.
