Can GRP Roofing be applied over felt?

From Malcolm Fisher


I have a felt roof on the top of my garage and wanted to know if I can apply your Fibrelast GRP roofing materials directly over the top?



Hi Malcolm,

While it can be done, it’s really not recommended and could cause you all kinds of problems in the future. Always better to be safe than sorry and put that extra bit of cash into stripping the existing surface, laying some fresh boards and applying from scratch.

If you want to over-coat your existing surface, I would recommend you check out either Overkote or Fibrecoat.

Hope this helps, if you have any more questions please give us a call.
