If a slate has slipped or shifted from its position then it is probably due to corrosion of
the supporting fixing nails.A slate ripper is a flat tool with cutting barbs at the end.
Slip a slate ripper under the centre of the slate. This will enable you to locate the
hooked end over the fixing nail. The steel blade slips under the slate until one of the
barbs of the arrow shaped tip hooks round the nail that is driven into the roof batten.
Once
engaged, pull out the nail by pulling down on the tool or giving a hammer blow on the curved
handle. If the nail is proving difficult, the tool will cut through the nail. Repeat the
procedure with the second fixing nail and remove.
It may be necessary to remove both fixing
nails before slipping the slate back into position. Slate rippers can be hired, check out
the prices before purchasing the tool see Hire Shops for more details.
