Roof tile cement

Andrea B.

Hi. I need to replace a few ridge caps on my own roof that has black roadstone roof tiles. Relating to the cement, what exactly is it? Is it just dyed cement or is there a specialist name?
Thank you.

Its regular mortar with a black die added into the mix you can buy it in most hardwares or the tile supplier will provide it!

Better to use Flexim, linseed oil and EPS beads in a matrix, won't crack and fall out like cement/mortar.
Sticks the ridge tiles down and when they expand/contract in the heat and cold it moves with them.

Thanks Jollyman. CJHaughey, could you elaborate for an amateur. Many thanks.

Most if not all builders suppliers will have Flexim in stock, it comes in red and black and is a type of sealant that air hardens.
It still remains flexible unlike mortar which is rigid, during the summer the tiles heat up and expand and on cold days they contract. This movement is allowed for in the joints between overlapping tiles but when you use mortar to fill the gaps on the ridge tiles it does not move instead it cracks and falls out over time.
So my recommendation is to use flexim.

Very good. Found their site too.

Nice one!
Just a tip, when working with flexim use a pair of disposable gloves it is sticky stuff and while it cleans up easy its nice to be able to ditch the gloves after using it.

Cannot get stuff in Galway (found one place with some red stuff left, but they haven't heard from an agent in years. I need black).

Flexim Holland have not replied to my emails and their listed agent for Ireland in Limerick, has not dealt with them in years. May have to revert to cement.

It's a pit as I was looking forward to trying it:rolleyes:.

If there's any building materials sales agents reading, at least there's a possible "live-one" here, as all the places I inquired, had had previous inquiries.

I wonder if you could add a latax addition to the mix. I have used A latex additive when using flooring compond. It makes the compond flexible when dry to prevent cracking.

I have a tub of it in the van .

I might do an experament to see if it would work for pointing ridges.

Cracking morter on ridges is very common and is a problem.

I have seen it in Cork Builders Providers, maybe you could get them to post it up?
Not sure how much you need but it is not very heavy.

At last I did find it, but at €78 a box it's a tad too expensive for me as original job has got bigger and there's a now a valley to do.I'm going the mortar route.
Thanks to everyone.
