I spoke to a local roofer recommended to us by a friend. We thought we may have a leak. He came out a week later. We didn't have a leak and thought it was condensation from the heating boiler. Today we have received an £80 call out fee. There was no mention of a call out fee before or during the visit. If there had of been we would have de lined the visit. Have had other roofers in the past who have not charged this fee. What should we do.
