Tile Roof Question

[D4D]

Any roof tilers on myswag? I have a concrete tile roof that is starting to get/look old and I am thinking about repointing and a reseal. The reseal guys say it is the ducks guts but roof tilers say it is a w@nk.

I'm not a Roof Tiler, but we had ours done a few years back. I was a bit sceptical about a "bit of paint and mortar", however having kept a close eye on it, 7 1/2 years later it still looks great. The paint they used was a rubber compound I believe and added a little bit of extra flexibility in house movement. There's still a few cracks, but the house moves around about 4mm - 8mm each year. I measured it for a few years 3 years ago. So it's not too bad considering how much the house moves.

Not a roof tiler but a licences builder my opinion is you get what you pay for. Cheap price cheap job. It needs to be cleaned properly re bedded and pointed primed and painted with a high quality flexible paint usually $5k plus. I think it is worth it as a reroof would be more than double that usually

Im not a Roof Tiler only  a Roof Plumber ( Metal Roofing)
If its not leaking and your just trying to tidy it up Go for it
If its leaking you won't fix the porous part of the tile that rubs together that lets the water in because they dont lift the tiles up to spray under the lap of every tile

Agree. Ours wasn't cheap. My only complaint was there was water/paint run off stains down the sides of the house, from where they cleaned the roof. Within a week, someone was around to clean all the areas and more.

Well they're both right for the following reasons. Provided your tiles are not broken or cracked they won't leak and you're only painting them for looks. Don't laugh I've got a terra cotta tiled Tudor in Adelaide with nice character moss florettes all over it and a year or so ago some young punk tried to tell me how they could get rid of them and paint it all one colour for me. Go tell it to the Romans kid.

As for pointing ridge and hip capping, again it's a matter of aesthetics as the bedding in cappings always crack with movement in the roof timbers over the seasons(not so steel framing) swelling in winter and shrinking in summer but providing large chunks of bedding haven't fallen out allowing wind driven rain egress, the mechanical overlap works just fine(seen those meditteranean type tiled rooves with no bedding and caps just nailed on?) Indeed when bedding the cappings the pros deliberately poke small drain holes in the bedding at regular intervals for that very reason.

You want pretty you can pressure blast clean and paint yourself with any good quality roofing paint for the purpose (ask at the quality paint suppliers) but recapping properly means stripping the caps and cleaning off all the mortar, then rebedding with soft lime mortar mix and then repointing with the appropriate coloured pointing mix (comes in dry bags) Problem with that is you inevitably bust a few caps and the odd tile and need some spares on hand and most' spray and run' roof painters don't do it but just chuck a bit more bog on and paint over it all and naturally chunks start falling off again, current affairs, tears, yada, yada.

You do it right or you leave it alone if it doesn't leak and if you're paying someone to do it make bloody sure they do it right and check their past work carefully before you engage them and get it all in writing.

Just make sure the guys that do the job don't have Irish accents

We had ours done about 12 yrs ago. What a bloody hassle that was. It seriuosly needed repointing so that was OK, but then the guys that were to do the respray seriously botched it. The cleaning was not done satisfactorily first time so the paint wouldn't take properly. Lots of agro later we had the entire roof redon under warranty.

No this was not a fly by night company. They are still trading and are one of the larger more modern  companies that do roofing.
Now the roof is again in dire need of a repaint. The capping etc is still fine but the paint???

If I had my time over I would get the capping repaired as required, then have the roof cleaned and sealed with a clear coat. No way in the world would I ever entertain the idea of a re-colour again.

[D4D]

Some good food for thought. We have a few broken tiles, just edges, and some of the pointing on the ridge capping is falling out, to the best of my knowledge it is not leaking. Might just get a repoint at this stage...

Today's roof is pointed with a rubberised mud which is flexible comes premixed in drums. Research the steps for the respray  and you will see there is a big difference between the type of paint and the amount of coats applied .Cleaning is cleaning , they either do it properly or not. So personal recommendations are better than big advertising budgets.

Hi,

Make sure the repointing is done with the flexible premix mortar, it last much longer, ours was done a few years back and still not a crack in sight.

Quick question along the same 'roofing' lines. We have a Colourbond (Mountain Blue) roof on both our house and shed that has delaminated.  It is well known in the industry about this problem. Long story short, we have been offered as 'goodwill' from BlueScope Steel, the option of going halves in reroofing the house, (lot's of $$$) or contributing to a repaint, that they assure us very effective and comes with 10 year warranty. Neither option suits us, but can't afford any more solicitors fees over this.  So, we are thinking the repaint, and just being done with it. Concerned though that we will be in bigger mess and disappointed in the future with the repaint, than just leaving it looking really bad and flaked.
So, how effective and long-lasting is a repaint on colourbond? Is this a good option? 

Apologies to the OP, but thought jumping onto this thread was a better option than multiple roofing threads!

I'm not a roof tiler but I've been on more roofs than I can count for emergency repairs.  I can say that the one thing I really dislike is when the owner tells us (or doesnt tell us) that they have been resprayed.  Sure it looks nice but it masks the age of the tiles which is a good indication of how brittle the tiles will be, also they are usually slipperier than new tiles.  I've refused jobs based upon the risk factor that my team is likely to slip or break more tiles.  If they are covered in heaps of moss a good clean will usually do the job.

If it's not leaking go with the repointing as you'll get your best bang for your buck.  I've slide more than the odd ridge capping back into place to resolve a leaking roof (usually when it's bucketing down).  I wouldnt worry about corners missing off tiles unless they no longer overlap properly, then get just those tiles replaced.

I help out a roofing mate of mine on occasions and I cannot remember one roof we have done that has been sealed with one of these mickey mouse roof coatings that has not rusted out under the roof fixings (cyclone fixings up here in the north).  As near as I can guess the following happens:
when the roof is sprayed it is done from peak down to the gutterline, this seems to ensure that there is a build up of paint sealing the bottom of the corrolock but not much at the top due to the angle that the paint is shot (from below).  I postulate that the water seeps in from the top and is locked in and pools under the fixing, because when you pull the screws there is invariably many of them wet under the fixing and the screw hole is rusted out.  The only way I can see to overcome this is either unscrew the whole roof before painting and replace all the fasteners (not a bad idea anyway because the neoprenes are usually stuffed due age) or you would have to shoot the paint from the gutterline backwards up to ensure a proper seal around the top of the fastener with perhaps a chance for the water to drain out the unsealed downside of the fastener.   This is of course just a theory of mine, untried.   I don't know of anyone who has come up with another solution other than replacing the tin.  From what I have observed though, this sealing process cannot save a rusted roof, just delay it's replacement by a few years.

I repainted my corregated gal roof a few yrs ago.I used a corregated wire brush then used a corregated paint roller to apply Dulux roof paint which is water tank friendly.Sold house but last saw it , it looked good after ten yrs.Remember any paint job whether spraying the Porsche or brushing the paling fence preparation is he key.
Just finished night shift so spelling and grammer is prob crap but I donn;t care.

Regards degraded paint on Colorbond (Bluescope/Lysaght drop the u like the Labor Party) you need to understand that their paint system is on top of Zincalume so you have the life of Zincalume sheeting anyway. The top is undercoated grey like the underside and also gets the colour coat on top so the question is are both coats peeling off or is it just a case of the colour coat peeling, degrading or fadind off, bearing in mind dark colours fade quicker than light ones.

I'd assume it's largely degraded top colour coat, with the particular colour you have and given the undercoat and Zincalume base underneath, it would be quite satisfactory to prepare and paint for looks again, rather than any corrosion protection concerns. Bear in mind though the Colorbond finishes are baked and generally hold their colour better than non-baked paint finishes, although in your case that's a bit academic now.

Edit: Here's the good oil on Colorbond-

Thanks MH, replied to your PM, but got an error message, and seem to be unable to resubmit it!

Can you check if you got it?

Thanks for those responses everyone. 

To be clear, the roof isn't corroded or rusting, functionally it's fine, and the words of Bluescope Steel "will continue to provide us with many more years of service". That colour manufactured at that time is faulty, we wouldn't be having this issue if we chose a different colour. The problem with it is purely aesthetics, but who wants a dodgy looking roof that is delaminating, through no fault of there own, rapidly, we believe, devaluing their home?? We expect and accept that colourbond fades. The zincalume is showing through where it has delaminated.


Apparently quite a few people have taken the repaint offer, so we will try and contact some of them to see how happy they are so far, and will go over the process with the contractor should we choose to go with the repaint. The 10 year warranty makes us think it must be an ok system - as long as the original flaking doesn't keep occurring, simply removing the new paint! I guess preventing  this must be part of the proper prep work though, believe me, we're not the only ones with this issue with them.

This could be an example for the other current thread about quality, and what do we accept.


Thanks again guys,

Dee.
