Anybody got any recommendations for sealing a flat roof. It's a large area (at a very rough guess about 180m2 but shared with others) and everyone is having the same problem. Builder is not interested as the building is now more than five minutes old so I think it's up to us. Looking for a cold applied waterproofing that can be put on by brush or squeegy. A bit like rubbaroof, polyroof protec or alike. Anybody used anything in TRNC like this or does the weather make this a no no??

Any roofers who would like to quote on it let me know..

John.

Check out the video.



This flat roof used to leak,after they sealed it they blocked off all the drainpipe holes and filled the roof with many tons of water,and left it for 3 days. You can see the membrain that was used to stick to the roof through the water.





Job well done.



No Leaks.

If you want a very experienced roofer who has worked here for 20years call Celal 0533 834 1957 good work and fair price. You will need a turkish speaker though his english is not very good.

Zero, I would be more convinced it they showed the inside of the flat roofed building! They could have a waterfall inside the house and the roof would still look like this....

Looking at the product, I think this is a bitumen based membrane which needs to be sealed with a blowtorch on seams and edges? Not quite what msg 1 is seeking.

If the flat roof is a roof terrace then I suppose the sealed roof could be tiled over once you were sure the seal was good.

Hi Johnatcastle,

Our friend had work done by sheffpants.

No problem since he did the job.

Can't get a better recommendation than that

CDS, message sent via your website.



Thanks Deniz but my Turkish is non existent. I am not in Cyprus at the moment but there is access to the roof anytime. Could I PM you the details for him to have a look and quote it?

I shall be back at end July so could tie up then if price and service is ok.

Thanks.

John.

Although Bitumen based sealants/coverings would be ok,(short Term) I would be concerned about the high Ultra Violet radiation causing damage to the the bonding . I would rather use a product such as "Vandaflex" ,this is a cementatious covering with silicone elasticity,and is guaranteed 15 years..I think Bitumen coverings,at best are 5/6 years,and are only as good as the guy that does the job....."Vandaflex is available in the DIY stores in the South..

Message 9.



The owner of the block done it himself,he was in the same boat as yourself,brand new build and the roof was leaking,so he got on with doing it himself,and up to now no leaks even with the heavy rains we had,under that roof there are 2 apartments,both bone dry.

Thanks Martin, yes I agree about the bitumen based covering which is why I asked about the cold applied stuff like rubbaroof. I Have googled vandaflex but can't find any info at all (which is a bit worrying) so can't compare it. Have you used it on a roofing application? Can you apply it straight onto the current coating or does it have to be applied to concrete. Does it need to be primed 1st? Sorry for the questions but since I can't find any info....

I am sure there are products in TRNC for this application?? Maybe I should think about bringing some. About 1kg per m2 so about 180kg wonder what that is in excess baggage...LOL

msg17 Hi ,Google Vandex Cemelast, it is the more popular of the two.No it does not need primer ,but wet the concrete roof before application,it is most important that you shade the mix to allow it to cure slowly ... good luck



If you need more help just ask...

Hi Martin, very grateful for your info. I am not sure that that will be the right product to be honest. It has to be applied directly to the roof meaning the removal of all the existing crud that is on there. Also not sure how practical it would be to 'shade' all 180m2 of it. Might have been a 'goer' if we could have put it on at initial build stage but the builder has had two attempts to seal the roof so god knows what's on there. What i need is a coating that will go on top of other coatings and seal the lot! Any idea's on a product for that??

What is the existing CRUD, bitumen,felt,mastic, etc.; I need to know because the sealants I have in mind will be governed by the material used in the previous attempts....

Hi Martin, sorry I do not know what he has put on there (all I know is that it doesn't work...!)

I have a couple of companies going to see the roof so I will see if they can advise on existing covering. We can go from there then.. Appreciate your time on this. Thanks.
