I would not recommend this company at all. I had the foam spray onto my garage roof in June and two months later I now find I have got a leaky roof. The so-called surveyor i.e. a good salesman promised me a 10 year guarantee and my roof would be fine guaranteed for 10 years. I called the company down and the guys did a patch up. While they were here for office phoned and said I had to pay another £265 otherwise they would call the workmen away. This roof has now cost me almost £2000 and I am never back to square one with no guarantee and have to get the roof redone again.
