Buying a house, issues with the roof highlighted, need estimate!

After a homebuyers report, the following was highlighted .. is anyone able to provide a free quote/estimate so i can see if i should proceed with buying the house? “The chimney breast requires making good, and there was in the loft area Wet rot to the purlins and pointing required to the outside gable which requires scaffold, some over hauling of the gutter joints a rotted section to the bay area. Including making good to the pebbledash and spalling of brickwork.”
