Liquid rubber flat roofing system for new flat roofs or roof repairs

We have been using liquid flat roofing systems for some years now. The old style GRP or Glassfiber flat roofs are becoming a thing of the past because of the difficulties on laying them and their rigidity. Liquid rubber and flexible polymer roofing systems have taken over a large part of the flat roofing market. The ability to flex over the duration of its lifespan is necessary for a flat roofing system. The application known as wet on wet has taken over thus allowing a new flat roof to be finished in a day. Also, the newer liquid roofing systems are able to be laid at 0c and rising and the flat roof can even be slightly wet as this helps the activation of the product. Other benefits of the new roofing system are that they are virtually odour free and can be used next to air-conditioning units on existing roofs, so perfect for overlaying old flat roofs that still have working plant on them. Unlike the old mineral felt roofing or asphalt roofing systems these new products don't need to use an open flame and thus the worry of fire is not an issue.

    Hi Steve, great video. Highly informative. I’m a chippie/all rounder based in the Channel Islands and have used the system you are demonstrating as its a quality product. For the past 10 years I’ve used Dacfill HZ and before that I used Decothane. Have you ever used those products? And do you know of any better (or cheaper)? Cheers mate. Craig Stewart

    Great clip thanks, I need to coat my felted garage roof, I’ve had a couple of minor leaks lately, but i cant complain, its lasted for 20 years.
    This product looks ideal, my only concern is, if it peels off a plastic bucket that east, will it peel from the surface of the roof, which is felt with a coating over it?

    I’ve a corrugated garage roof that seems to have lost it’s waterproofing , there isn’t any leaks as sure but the roof seems to absorb the rain then it drips inside garage . If the roof was cleaned , would painting this stuff onto the roof cure this problem? I’m not sure if the roof is concrete or asbestos, it’s 28 yrs old & built by Marley.

      @Steve Roofer Thanks – it’s for my own place so I can take the time. What I was wondering about is the area where you have the membrane hanging down loose into the gutter with no timber behind it; did you do that in situ and if so did you have a backing behind that you peeled off? I’m assuming you didn’t just make it ‘in the air’ as it were…?

      Hard to describe how but its made a lot easier when you have time on a job to do the buildup I was on this job for about 8 days so did the timberwork first then overlaid it with the Hydrostop AH-25+ roofing system leaving a small drip detail overhanging

    Great video steve. I have used the desmapol/Permaroof system on a few jobs. Tbh i fjnd them very awkward to use. Especially vertically. I forever got pin holes just as the material was about to cure. It has its uses but i find rubber or grp to be better. I am going to do the restec flexitec course. Have you used this?

    1. Steve Roofer

      The system above is AH25 and is really good on verticals it’s also good as there is no mixing and no small so its very user-friendly I haven’t used the Restec Flexite system so report back when you have used it will be interesting to know what you think

    Steve – I have a square bay with a flat roof and now have a leak where the roof joins the rest of the house. Can I use Isoflex on this. I think the flashing is damaged so can I paint this stuff straight on top of it or does it need a primer first? Should I send you photos?
