Replacing Lost Roofing Slates - How to Secure the New Slate

Lost slate replacement, re-using a slate salvaged from elsewhere - note the exposed nail hole which would have been covered by the next course in the original placement of this slate
Red slate roof, generally excellent but with broken damaged slates at eaves, possibly during ice damming or installation of heat tapes. Heat tapes at a roof edge are themselves evidence that the building has experienced a problem with ice dams and leaks at the eaves.

Examples of Poor Repair Work on Slate Roofs - Temporary "Fixes" to Slates

Slate roof coated with roof cement, mostly washed-off. While roof cement or mastic is not a long-term durable repair nor even a proper one for slate roofs, we'd prefer this stopgap measure to seeing someone abandon and destroy a salvageable slate roof. The complete coating of a slate roof with roof cement or other sealants is an extreme measure and unlikely to have a long life however.
