    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.

    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.

    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

    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.

    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.

  • @tom-dn8md
    @tom-dn8md 2 роки тому +2

    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.

    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.

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?

  • @RoofingFacts
    @RoofingFacts 8 місяців тому

    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.

      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

    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.

    Can this take daily foot traffic? I have a terrace house on a steep hill, our back doors are accessed via a concrete balcony that's always leaking 😤
