It used to be "Tarmac yer drive soor" [Touch forelock] I've got a bit left over". In Worcester every other day I find a pikey standing on the front patio gazing thoughtfully at the roof and its "Clean and treat yer roof Soor." "Wont cost much." When did the change over occur? Is it the recession, and is this epidemic of roof treatments reflected in the rest of the country? :?
