Flat roof leak

[Gooner100]

Hi we have a flat roof that has developed a leak. The surface is bitumen with a metallic coating underneath. Is there a product recommended to fill small holes in the surface?
Thanks in advance.

Hi, It depends on the thickness of the bitumen, if it is pure bitumen you could get a blowlanp on it to re-melt it around the holes so it flows in to seal it.
Other than that you'll need to replace the area covering. a liquid rubber roof is ideal for this so speak to your suppliers in France. I use rubber4roofs in the UK.
