Frost damage to verge

[wadihalfa]

Hi Folks,

First winter in my new house and every morning I find lumps of mortar on the patio that have come from the roof verge. (see photo). The mortar is soft and crumbly and like an OXO cube (for the cooks among us). Very little if any cement content.

I'm happy to go up a ladder or get a scaffold tower and re-point it myself (when the weather warms up a bit) but don't want it to be an annual event.

What's the best way to tackle this with regards to preparation, materials to use and aftercare.

Thanking you in anticipation ...

SK

Is this house new build or just new to you?
If new build (low odds with that verge) then get the builder back in.
If new to you then tower not ladders, rake out all that pathetic sandy muck, redo with 4:1 or 5:1 sand/cement, should get 20 years out of it

Oldbunotdead,
For my own interest as I also need to do this at some point,

When you say sand, do you recommend
- Sharp Sand?
or
- Builders Sand?

Thanks, SFK

Thanks, oldbutnotdead.
Yes the house is a new build. It's a one-off built by a local builder and then put on the market once complete.
The local council specified that no facia boards were to be used.
Having seen the quality of the work since moving in, the last thing I want to do is get him back to do more
shoddy work.

Nightmare. If you want the verge to look weatherbeaten and rough from day 1 (and make it more difficult to wodge enough muck in the gap) use sharp. Soft will be easier to work & give a smoother finish. Whichever, try and get 75mm or so under the tiles.

You actually need that to be re done completely and not just repointed - pointing will fall out this time next year.

I'm not sure that is going on with that angled piece of mortar below the verge, but that's just wrong and will allow water to just run down the wall not drip off away from it
