Chapter 1: Is a full re-roof worth it on a 1970s Brighton Hill house, or can it be repaired?
What we find
The estate was built over a few short years around 1970 to the mid-1970s, so many Brighton Hill roofs reach the same decision point at the same time. Concrete interlocking tiles last a long time, and the tiles themselves are rarely what fails. The things that wear out are the felt underlay beneath them, the timber battens they hang on, and the ridge and verge bedding. A roof can look weathered and still be sound; it can also look tidy from the road and be leaking inside.
The signs that point toward repair are scattered problems: a few cracked or slipped tiles, a stained ceiling in one room, a ridge that has opened. The signs that point toward replacement are everywhere at once: tiles crumbling at the edges, sagging in the line of the roof, daylight through the underlay across the whole slope, or battens that crumble when tested.
What we fix
The loft tells us more than the road does. We look at the underlay and battens from inside, lift a few tiles to see what is beneath, and photograph what we find. If the fault is local, we repair it and the roof carries on. If the underlay and battens have gone throughout, then stripping and re-covering is the sensible option, usually with new breathable underlay and battens and the existing tiles relaid where they are sound.
A full re-roof of a three-bedroom semi in concrete tile has a typical UK range of £6,500 to £10,500, so treat that as a guide: your fixed quote follows the survey. A job of that size is notifiable, so we deal with building control, including the insulation requirements. If you are tempted to switch to a heavier tile, the structure may need checking first, because a covering 15% or more heavier needs approval.
