Seal crack roof tile

Toolstation do a cheapo angle grinder for

JoeJoe,

Not sure where you get your silicone from, but I get mine from local suppliers (not the likes of B&Q etc) for between of £1.50 to £4 - depending on what I want it for!

Jethro,

Replacement is better, but you can smear some silicone mastic on the edges of the tile, push the two bits together and leave to dry and cure - that should last for quite some time as a temporary stop-gap.

To make a more permanent job, remove the tile and nail a lead 'tingle' [1] under the tile to the batten, let it hang down about two inches or so past the bottom of the tile, replace the tile, apply mastic as before, push the bits together and bend the lead up over the bottom of the tile.

"not far off" was my point. £4 or so for a tube is what I had in mind compared with low teens for a grinder that should last beyond this job.

And don't forget to drill a small as possible stop hole at the end, or beyond the end of the crack to stop it propagating if you fill/seal the crack.

Or that new FT101 stuff

I temporarily repaired a roof tile (was up for over 4 years....before I got round to replacing) by PVA'ing the two edges of the tile, gluing using standard clear silicone (happened to have around) but also glued a spare peice of lead flashing on the underneath of tile using no-nails.

Was very surprised when removed 4 years later was still intact and even had great difficulty removing the flashing to be used in any future bdogings....
