Product reviewsRonseal Thompsons 4L Roof Seal - Black (30146)

seals the problem!

I was cautious and sceptical about this product doing what I required. It is remarkably easy to apply, so much so I doubted it sealing the problem. A few months down the road and the small flat roof section has remained watertight.
As for the ten year guarantee, who can say? I would, and have, recommended this Thompson's Roof Seal.Read full review...
