How to Repair a Roof

When it comes to the roof, it’s common to find defects flagged up in Home Buyer reports and building surveys, which have a unique capacity to evoke dread. Even straightforward repairs that involve working at height can induce bouts of financial vertigo, brought about largely by the substantial sums to pay for scaffold hire.

Fortunately, the need for complete re-roofing is comparatively rare. There are, however, potentially serious issues that routinely crop up in surveys, most of which require urgent attention to prevent leakage causing deterioration to the structure. Here, we explain what to look out for, the repairs required, and the potential costs* involved.
