How to Repair a Flat Roof with Liquid Roof

[@lnostdal]

Great vid. I got to say it amazes me that people build roofs like these in a country where it rains 350 days of the year.

[@azizaelamri]

I know crazy ...I wish I knew before buying my damm place:(

[@dpowers9242]

Super helpful, a nightmare contractor left my roof unbolted for three months and it literally ripped in half and blew into the neighbors yard, This video really helped me get some time to patch it up until i rebild it. Used all of these tips and made it through a really heavy winter. Thank you so much.

I'm loving the white pipework on the building next door going into the soil stack timed at 0.50 into the video

[@KilliKonKarnage]

Brilliant stuff just what I needed. Been almost 10yrs on a felt roof. Might even put this on top of those sheds!

[@gregoryclark7566]

I like how seriously you do your work. I would feel confident if you repaired my roof.

[@brianwood5220]

Lovely job Roger, be nice to revisit in 5 years time, just to see how it's doing and is the client happy with it?

[@Qcmbr]

Just done my flat roof in it. Wear clothes you can throw away (bin bag at foot of ladder!), wear kneepads so that if you have to kneel in wont seep through and glue your trousers to your knees(!), 1mm coverage per coat really is enough if you aren't laying fabric down - if you are putting fabric down you'll need much more or the fabric will struggle to soak enough in to adhere. Fabric is a nightmare as it puckers and will stick to your roller - paintbrush for fiddly, hard to reach areas. Buy one extra small tin for after it is all 'finished' and set to fill in any gaps between fabric and missed places. Cut any fabric to size before you start - after you start the liquid roof is getting on your hands and then onto any tools you use - it is not removable during the job. To open the tin I had to use a large flathead screwdriver and then pliers to peel the tin lid up. Wellies were better than boots for me. Pour straight from the tin onto the roof - it is very thick and you'll waste a lot of you are decanting. Wear proper gloves. Potentially warn the neighbours - this stuff will stink up the street and people may need to close windows. Take a drink up with you as once you are plastered in it moving up and down is messy. All said too 4 hours to do a flat roof 10 meters by 3 (2 tins 21ltrs - fair bit left over) - would have been easier with an extra pair hands. Really good result though.

Did it work? Any new leaks since the job? Please update in the future too!

Amazing what a good plumber can put his hand to nowadays. Great job as always. Now I know what to do with my flat roof. Thanks 🙏

[@rajivvashm6046]

Roger , great video (again !). Perfect solution for the flat section on my loft Dorma. Yep, the roofers said complete rip and start again; (& yet these materials can't cost more than few hundred pounds) - top man.

[@raymondmontgomery4795]

Thank you for the video. Not sure what the product actually is but i am thinking we would have a hard time closing any quotes with all that is needed...Not a fan of elastomerics but for some roofs that don't really need to extend their service life so many years out i guess it is an OK fix. Our company has used pretty much everything out there over the last 25 years. We use only one products after 8 years of success and not callbacks. There is a Liquid butyl rubber made by epdm coatings. What we like about it is that it does not need a primer for any of the roof types we have applied it over that goes for metal, BUR, epdm, foam but NOT silicone. Also it is a one coat application so we close much more business with this product because we come in as the lowest bid! It is a solvent product so primarily the reason it last all the years. I guess every product has a particular use but as a roofing company we want to use a product that will last and has a history of success. Looking forward to your future videos thank You

Roof repairs don't cost anything, it's on the house. 😎

[@lazylad2336]

Concrete roofs are known for problems. Bitumen won't stick and paint cracks. That blue stuff looks decent👍👍

[@iantarncarpentry4285]

Nicely done Roger. Proper job, that roof shouldn’t leak now!

[@tanja8907]

It will in a few years. Nothing to do with Rogers workmanship, its just these products are rubbish. If you dont believe me come back to this post in a few years and ask skill builder to ask the customer if it's leak free.

[@SteS]

Nice one Roger. I was going to go all out and do a GRP system on OSB to seal a flat roof to prevent rodents gnawing through the OSB. The roof is under another roof and this looks like the perfect product. Saved myself a couple of grand!

[@tanja8907]

Do it at your peril. Trust me, if you do this you will wish you'd done a proper grp roof in the first place.

[@SteS]

@@tanja8907 I didn't see this notification until someone liked it. Can you explain why?

[@teach1913]

@@SteS thsi liquid rubber seems more like a patch repair, i wouldn't trust the longevity. Do it right the first time so either GRP, rubber roof (which is quite easy to lay for a diyer) or get roofers to felt it. Hope that helps

[@KendalSmithy]

Interesting because just today I recoated a concrete garage roof. Last year I did it with one coat of Evercryl Grey but ran out and finished it with Bostik Flexacryl Grey. Since then the Evercryl had cracked in a few places and begun to peel where I had coated it too thinly over the previous layer of bitumen. But the Bostik Flexacryl was still good, so today I put a second coat of Bostik's Flexacryl over the whole roof. I'll be checking it again next year to see how it stands up to another British winter.

[@audio_poetry]

And? One year passed since your comment. How's the roof?

[@alisimbule8333]

😂

[@peterwood3108]

Around three years ago, we tried a product out on flat roofs called Polyurcoat, there were lots of problems. All we did for weeks on end, was to go back and fix each roof, with Rinus shield.

[@walter.bellini]

Roger what a delight you are! I have been watching and enjoying your wonderful informative videos You have a way of delivering information in a way that is easy to understand, and you arrange things so that you build our knowledge Thank you

[@sirbillmumptono.b.e.3946]

Many thanks ... just what I was searching for. Every angle covered ... nicely explained etc.

[@noskills9577]

I’ve used the fibre paint several times for repairs and it’s handy stuff.

[@HeathenGeek]

alright mate. When it was first done, that pipe was supposed to be painted with bituminous primer, then would get a couple of layers of torch-on (2mm, then 4mm) up to 6 inches above the pipe so it forms a collar. So, although they've already paid 8 grand for 'the pros', it doesn't seem like they actually knew what they were doing. Anyone can do nice easy flat bits, but it's the details where it really matters. A roof like that, done properly could literally be used to keep water in a swimming pool without ANY of it getting through at all. Shame really, there used to be some really talented fckrs doing this work back in the day. Love the vids mate, keep em coming 🙂

[@jem8472]

Looks good. We have just found out the issue with our front porch. There was a gap left so the water runs down the outside wall. Just need to figure out how to patch it but can see some of the obs has rotted away. I might be able to patch it with this stuff.

[@tom-dn8md]

Right, fair play for having a go as a hands on fella. Few points. Wet on wet rule of thumb 2kg per m2, fleece, 1kg per m2. Laying the fleece over the first layer of liquid, you must fully embed the fleece (missed in the video) take your roller and dry roll the fleece till you see the liquid coming through it. Then apply the top layer. If you don't do this the roof will debond and come up in winds, likely to happen here unfortunately. Secondly mouse holes in the felt laps. Patch to have 150mm laps onto area. Don't use the fiber as it's for difficult details only. Cut a square of fleece amd do 2 layer wet on wet as above. 3rd rule. Go to a manufacturer such as Bauder and ask them to spec the roof. The guarentee is insurance backed and covers products and workmanship for 20years minimum. Roofing is full of have a goes and pretenders. Go to a commercial contractor that's doing large scale projects, they will do your roof and do it properly. We are such a contractor.

[@edwardmurray8507]

Wow so for 27m2 I need 54kg of the liquid?

[@tom-dn8md]

@@edwardmurray8507 2kg per m2, then fleece followed by 1kg per m2 on 27m2 = 81kg

[@domenicobartoccioni1610]

It is interesting, and I am seeing this video just a couple days after we have recoat a previously waterproofed concrete rooftop with liquid coating and reinforcement of our own

[@boyo57]

Like most trades you get good and bad, a good roofing company would really need to strip this put in roof vents to let out the moisture trapped in the concrete through ingress of water. What youve done looks good now but in two/three years someone will be doing it properly with a professional system. Good "temporary" repair though but not permanent, it will have more cracks than a Jack Whithall gig in a couple of years once the UV have haf its way (despite what it says on the tin) the customer obviously didnt want to spend a lot. Theres an old saying, you cant polish a turd....but you can dip it and roll it in glitter. Good effort for a repair👍

[@richiej5812]

It seems that alot of negative comments on youtube are possibly from "professionals" who might be losing work these days considering the information available these days to your average homeowner

[@yusuihang]

How long does this product last before you would need to reapply? Is there a warranty period? Didn't see this information mentioned on the product website.

[@phillholdd5936]

Acrylic fibre coatings and Polyurethane coatings don't perform as well where there is ponding water or gutters , I would advise to check these areas regularly

[@mickyork41]

Most flat roofs look like bodge jobs to the untrained eye like me. This one finished up looking ok in the end though. Another great video!

[@cuebj]

Very true. Had ours done by a diligent couple of guys who came recommended, it still looks uneven and rough. Sometime after, I and a friend did the Selco all-day course on glass fibre roofing. We, and the rest of the students did decent jobs on our little projects. The teachers did something mindboggingly good. Clearly, you can do a decent job but I know I would not do as good a job on my own without being an assistant to one of the teachers for at least a dozen roofs. A lot of such training is a day - you do OK - then you're on your own and standards slide

[@Rabidavid]

We have pooling water on top of a felted roof covering, which has been put on top of a poured concrete roof, which drains the wrong way. What product / method should be used to level out the liw spots? Presume it would be best to remove the old felt, rayher thancover over with another product?

[@jarpartridge]

Great video thanks, Is there something in the range to deal with pooling/puddles. Im going to recoat my flat roof this summer and would like to build up the areas of pooling so they run off with the rest of the water.

[@grahamm987]

Great video Roger, This looks like a great product but to patch up the liquid roof I have spoken to Sika and they suggest that you may need a "re-activation" product before applying further liquid roof. Does sound like rather simple maintenance for the DIYer like me but must know correct way of adding more layers (or patches) - can you confirm?

[@insquirrel]

You, sir, just saved me about $6k. I can do this myself! THANK YOU!

[@RoofingFacts]

So there's two methods to spread that. We call them "dip and stick" and "slop and mop". Dip and stick is when you dip your roller in the bucket and spread it out, slow, thin, likely uneven, takes way to long bit saves material. Often good for a top coat. Slop and mop is when you pour it onto the roof and use your roller to essentially mop it around until it's covered. Thicker, faster, much better in every way except you use twice as much. Will last longer come out better. Best way to do bottom coat.

What would be an alternative to fleece used in the video?

[@bamsebrumbamsebrumen5403]

Flat roofs are always a bad idea, because they always have or will get tiny depressions where water can stand, which feed fungus and encourages people to walk on them, then leaks are literally guaranteed. I was a little surprised than the roof wasn’t given say like one degree’s angle and the depressions hunted down, but then I'm no roofie.

[@anjimq]

Will this stuff stick to roofing lead? Roofers bodged my fibre roof by trying to lay fibre on top of lead on the edges of the flat roof where it meets a pitched roof. Unfortunately they didn't prime the lead first and the fibre has now lifted away and water is getting in!

[@abbasmawjee5328]

Hi, Thank you for the informative video. I had an extension done some 5 years back and my builder installed a GRP flat roof and used the 'Cure It' prodcut. This is now flaking in places and there Is a small leak somewhere that I cannot locate. I feel that the leakage only happens when we have heavy, windy rain. Do you know which Everbuild product will be suitable to repair the cracked and flaky bits please? Will the Evercryl (with the fibre bits) be suitable? Any help and advice appreciated

[@gwilko6452]

Fleece backed single ply membrane would have been best for that job. We would only use liquid solutions in tight channels or difficult detailing. Hats off to you for persevering with it over a larger area. And reference to having the experts in before. They obviously didn't do a very good job.

[@dmc7324]

Great video, I have a garage with a concrete roof cast in three sections. I have tried everything to seal it but the joints always leak after about a year. Would I need the fleece to span the joints and compensate for the movement?

Personally I would use some fleece because it can do no harm. I think that filling the joints first is also good.
