Questions & Answers


Would this stick membrane from dry ridge system to a GRP flat roof on a loft conversion.


Good Morning Amarjit

No, this wouldn't work and could damage the GRP. There isn't a product that I could recommend, unfortunately. 


Please could you tell me if Ubiflex high tack sealant is suitable for sealing the flashing to polycarbonate sheets? If not what should I use? Thanks.


The suplpiers cannot guarantee it would work with Polycarbonate I am afraid, it may be better to select a Lead Alternative with self adhesive backing like the below options.



Some silicones react with lead flashings. If I apply high tack to lead will it have an affect?


Hi Tack is for use with Ubiflex so may not work, we would advise to use something like the sealant linked below.



Will this stick to asbestos garage roof?


Yes this would be suitable for Sealing Ubiflex to Asbestos Sheets.


Will this stick to cedar shingles?


Yes this wills stick to Cedar Shingles.

This was recommended to me for the through roof vent. As it was the first time I fit such vent I was really putting too much sealant, then shortly I came to the conclusion that at this rate I won't have enough sealant to go around the flange, so I passed how much sealant I put. At the end the tube was enough to cover the whole flange, but I would have liked to have another tube to add a bit more and just in case!

This product could does its job. Its viscosity could with being able to flow easier to run a bead. It was also not easy to put blobs where required because of pressure required from hand gun.
