It is important that all customers are fully aware of what may happen, this is what happened to us, the foam was removed on the agreed date/s , several tiles were damaged, dislodged, I contacted Mr Sweeney who told me he would deal with it, he did not and I had to pay a roofer to fix the tiles as heavy rain was forecast, Mr Sweeny did agree to cover the (minimal) cost. This was the least of our problems, the foam is attached to the membrane that is located between the tile and roof trusses, this membrane is completely destroyed during the removal process, the only way to replace this correctly is of course to remove all the tiles and refit / replace them. This company does not do that, they replace the membrane by fitting it internally so of course this is not in line with any building code and is completely ineffective, should there be and water ingress through the tiles it is free to run down any edge as the membrane is in the wrong place. Clearly on many occasions this is not spotted by the person representing the mortgage company as they just look to see the foam is gone therefore they will then lend on the property. In our case a surveyor checked the work as a loft extension was planned, he immediately rejected it as the membrane was entirely unfit for purpose. We had to reduce the price of the property by 20,000 pounds to cover the cost of a new roof, all the money paid the Spray Foam Removal was wasted and no refund was offered.
