How to remove roof slates without breaking them.
The tile is discontinued so it was worth the time.
Screw a harness anchor onto the rafters and tie the rope to it.
If you don t have a chimney or sturdy object on your roof slide 2 3 tiles on your roof up so you can access the rafters underneath.
Broken slates worn flashings rotted sheathing boards or any element of the roof can be removed and replaced without the need to replace the entire roof.
Pull the ripper down the line of the slates in an attempt to break the nail.
Working with roof tiles is a lot easier when you know a couple of basic tricks.
The broken one i superglued back together just one break and installed where it will be under a couch but you cant see the crack unless you know it is there.
Because of this unusual maintenance characteristic slate roofs can be made to last as long as the slate itself will last which could be hundreds of years.
This short guide covers how to use a slate ripper a useful tool designed for replacing slate roof tiles.
While you don t need a safety harness for a roof with a gentle slope you can still wear one if you want to reduce the risk of falling down.
Sometimes also called a slate slasher the ripper has a thin flat blade about two feet long with a square chiseled tip for and a pair of hooks cut into the side of the blade.
If just pulling the ripper doesn t break the nail hold the lower end of the ripper away from the surface of the slates and hit down the roof with a hammer onto the front of the handle the front of the handle normally has a flat face for this purpose.
And the only sure but slow way to remove them without breaking many is a slate rip which rip the nail out from under the slate then you have to wriggle the bent nail out of the hole.
