I'm a first time buyer anxious to complete on my house. Survey highlighted a problem with pointing? At roof edge. I have good pictures but can't get access for a roofer to look for 3weeks and I'm really anxious not to add further delays to the sale. Would anyone have experience of this sort of issue, I'd love a heads up on how significant/expensive it's likely to be? Time really is important as it's important to close sale asap. Thanks for any advice.
