Sorry to hear this. We got the lead stolen off our kitchen roof in August of this year. The scumbags damaged the brickwork tearing it off. I heard stories at the time about 2 men going round in a big white van asking for scrap metal and last Monday, (24th October 2011), I actually SAW them.
It was around 10:20am - 10:30am, I'd just finished viewing a house in Rice Hey Road, Wallasey and these 2 blokes in a white van pulled up and were eyeballing the property, (it's empty due to repossession), and they asked the estate agent if he had any scrap metal. The estate agent laughed and said "Sorry, it's not my house!" and the van sped off, unfortunately too quickly for me to get their licence plate.
Be on the lookout for this van and these men. It's just too much of a coincidence that they're floating around asking even PEDESTRIANS for scrap metal in an area where lots of metal is currently being stolen.
