Welcome to Plytech UK Ltd. - the sole importer and main distributor for Rubberall® EPDM flat roofing rubber and the designers and manufacturers of Quicktrim.®
It seems that the primer is a thin adhesive. why is the tape (additional layer of rubber and two extra layers of adhesive) needed? Everyone does it this way, but i dont understand why. the cost difference is very large, so there must be a reason why adhesive alone does not work for EPDM membranes.
Hi Stuart, Sorry about that but we would have been in the way of the camera if we were on the roof. It's actually easier to do from in front of the detail if you are not filming. Hopefully you would have scaffolding to help anyway. 😀
Hi, when adding fascia/trim detail to cover the area below the coping and above the roof, would it be a terrible idea to screw into the EPRM on the inside edge in order to secure the fascia? E.g., would that cause a rip in the EPDM down the road? I'd rather use butyl caulk, but I don't think it will hold-up long term. I would of course tuck it under the coping and use self sealing screws. And, is screwing through this type of flashing tape at the edge even worse or no different? Thanks much.
I have a question. Is there supposed to be any pockets where the rubber roof meets the side of a shingled barn side? Isn't supposed to be tightly secured?
Hi Fiona, Thank you for your question. If you coudl send across some pictures this might give us a better idea of what is required with your specific roof details. Please feel free to use our email sales@plytech.co.uk
As a building envelope consultant of 35 years I can't take this video seriously because attaching a membrane to OSB is just about the dumbest thing in the world. You have to use Quality Base materials that when they get wet will not turn into oatmeal
Hello Deputy, can you tell us what "should" be used instead of OSB3? If a waterproofing layer has failed, nothing cost effective is going to mitigate water ingress except a second waterproofing layer...
Hi, Yes the rubber can be adhered to brick or concrete using solvent adhesive. The flashing tapes can be adhered to most other materials also using the butyl primer for flashing tapes. I hope that this helps. Regards Marc
Having call backs on ply techs corner tape, their primer is too thin, the tape isn't flexible enough and doesn't bond properly. Never had this problem with firestone corner tape and primer but stockist switched to ply tech, guessing cos it's cheaper. It's annoying cos it's costing me money and makes my work look bad
Hi Dave, Sorry to hear that you have been having issues with the tape / primer combo. We have not had any other reports of this and our tape works very well in most other scenarios. Could I ask where you bought the tape / primer as there is a shelf life on these products (after 12 months the tapes can become harder to stretch as they cure over time). If we know where this was purchased we can make sure that the stockist has products that are in date. Kind Regards Marc
Hi fudgewaa, You could cut the rubber in the internal corners but any extra cut is a potential for a leak. My preference would always be to have fewer cuts if possible. As the EPDM is very flexible it is quite easy to fold into the internal corners, however I would advise checking that no factory welds fall into the internal corner as the rubber can become thicker in these sections. Hope this helps.

Been welding fibertite for 9 years looks like a good weld but I would suggest to keep that roller flat at all times . Bad habit to break for some aka stitch welding .
Rediculous ive been installing epdm 17 years can u make it take longer i would fire that jackwagon and throw his tools in the dumpster its painfull to watch this
Next time use more rubber, and cover the top of the wall and curb. Leak disaster if you think the cap metal will keep water from penetrating, or disallow condensation.
Sarnafil welded on corners with hot air and rollers gives me more peace of mind than using bonding materials. However, your job looks and has been made well.
Hi Ivan, we are glad that you like the look of the external corner. If we can help you with any EPDM enquiries please let us know. Our supplier also has a puncture & chemical Resistant hot air weld system (FiberTite) that may be of interest. Best Regards RubberFlatRoof Ltd 01392 927729
Hi Rob, Yes, EPDM is extensively used for Green Roof applications and is a very durable product that can often be installed in a single sheet which further reduces any water ingress possibility.
As an installer for Firestone. We got told on 1.16mm Fire rated blankets (Marked FR) as you show here getting installed, instead of the pond liner type ones at 1.0mm. The writing has to be facing up as the underside is coated only. 🤔 This was installed upside down - luckily no fire 😊
Dear Steve, This is an LSFR sheet for the EU (it's just that the fold in the rubber did not allow the LS to be seen). With the LSFR sheet there is no specific side which needs to be installed pointing up as the fire retardent chemicals are distributed throughout the sheet. This may be different with the US sheet? Regards Marc
Plytech UK Ltd I’m based in East Yorkshire also. We had to turn our Epdm rolls over as the manufacture of the rolls was rolling them outside in, so we fitting them as the manufacture was producing them. To be told by an authorised Firestone inspector. He will not issue the 30yrs warranty until We installed correctly. So the rest of the rools we had in stock for jobs, we had to make sure the writing was facing up (FR SHOWING) Different rules / different guidelines. Guess we also have the strict firestone verified checker then for the warranties.
Hi Steve, Apologies this comment has been overlooked. The EPDM performs the same whichever side you put down. Some prefer the serial number up in case there are any warranty issues, then it is easier to prove which supplier the rubber has come from. My preference would be to install with the serial number down and make a note of the serial number against the warranty info - that way the customer does not potentially have to look at a print across their roof. Hope this helps.
The only problem I have with these videos that are always made in warehouses is these are not real conditions. Installers do not have time to handle the rubber 3 or 4 times before glueing and setting it when the sheet is 130 to 150 degrees and burns you every time you touch it. The sheet will be set up to wall as close as possible and glued 100% and none of those cuts will be made till it’s actually being put in.
Hi Peaky_Blinder The roof edge is finished with either a mechanically fixed trim edge or with a tape system. Please let us know if you require any further assistance by emailing sales@plytech.co.uk or calling +44 1392 454810
@@plytechukltd3475 hi, not the edge, you can use spread trim for that, I'm talki g about the external corners in the middle of the roof, How do you deal the rubber flashing after you cut the EPDM, Being as it's impossible to vulcanise when you glue the flashing on how do you protect the glue that is vulnerable and will break down under water. How do you protect the glued rubber.
As long as you clean the roof well then you should be able to adhere down with contact adhesive. Any further questions just call us on 01392 454810 - Thanks
