How to repair verge on Monier tiled roof?

Hello,

I have an older 1968 house here in Canberra which is your "standard" Brick Veneer house. It has Monier Tiles on the roof. It has cement verges with barge capping or flashing/aluminium angle etc covering it. Towards the bottom on the valley or near guttering I can peek under the flashing and see that the mortar has crumbled etc. I would like to attempt a DIY repair but honestly from reading on the web people are saying the whole lot needs to be replaced at once (the mortar) but this is, or would be, difficult as the nice capping/flashing would have to be removed also. Not sure of the condition of he rest of it as its covered. Pouring rain and almost 11pm here so no photos but will take some tomorrow.

Is this worth putting some mortar/cement mix of some sort (like what do I use on the verges?) Or will this require a bigger than Ben Hur job as it goes up quite high to the gable end.

Thanks - Geoff

Hello @geoff_70

Thank you for sharing your question about your Monier tiled roofing. I have a similar tile on my roof and am lucky to have spares under the house which the former owner kept. If we were to do a bit of math 1968 to this year is 57 years. Let's say conservatively that the roof and its pointing and mortar seals were renewed once back 25 years ago. It would in theory be 32 years since the roof has been serviced. Unless you are aware of a time the roof was properly serviced then that would be the date we would need to count from.

If you have a very steep roof, I propose engaging the services of a professional as they will have the safety gear, experience and knowledge to repair and restore your roof. Small repairs will not be effective to the whole as only that small section you've patched will have any form of integrity. I suggest getting several quotes to see what the going rate is for your area. As much as I would like to suggest doing it as a D.I.Y I'm afraid that it is very involved and if you don't have the proper safety equipment and experience it could be dangerous as well.

In the meantime, if the roof tiles are still holding on, I can only suggest leaving them as is until the trades come back after the new year.

Let me call on our experienced members @Dave-1 and @Nailbag for their recommendations.

If you need further assistance, please let us know.

Hi @geoff_70

I would agree with @EricL on this and unless you're having an immediate water ingress issue, I would leave this job to a roof restoration professional as its quite a skilled job, especially in the location of concern. Booking one in asap will put you in the queue to have the repairs done as soon as possible after the Xmas break.

Good Morning @geoff_70

I would agree with @EricL and @Nailbag about getting it done professionaly, I had to look up "cement verge" in relation to roofing 🙂 But as soon as I knew what it was it made sense that the whole line should be done in one go. Which lead me towards getting it done professionaly.

No water ingress = lower priority
Water issues = bumped up my list

Having the roof look good = mmmm maybe 🙂

Hello all,

Thanks for the replies. I had the "roof-done" 3-4 years ago prior to solar-install but whilst he cleaned and sprayed/coloured the tiles (and yes I also have spares, also easy to find here in Canberra) I am not sure he did a wonderful job as other tradies have commented on cracked tiles etc which occasionally I come across and swap-out. I don't think (100% didn't) he looked at the areas in question. I'll speak to a roofer and get some quotes.

Cheers,

Geoff
