Heavy walls and a long-lived roof make people nervous about touching either, and a roof that has stood since before anyone in the household can remember feels like something to leave alone. That caution is sensible, but it should not become a reason to leave a leak running.
Q2.1How is a leak reached from above?
Most leaks have a small cause: a cracked tile, a split slate, a flashing pulled out of its joint or a valley that has silted up. Most can be reached by lifting a handful of the courses above, replacing what is damaged, and laying the rest back as it was. The roof underneath stays undisturbed, and so does the timber work that carries it, which is often the most valuable part of an old roof.
Q2.2How are new tiles matched to the old?
A mismatched tile on a plain roof stands out for years. We match by size, colour and surface texture, using reclaimed material where the original is no longer made. On a listed house, matching is not just a courtesy; changing the covering without consent is a problem for the owner, not the roofer.
Q2.3Can old timbers take a heavier covering?
An old rafter has carried the same load for decades. Swapping to a heavier covering changes that. Building Regulations treat a covering that is 15 per cent or more heavier, in the Planning Portal's wording, as a matter for approval, so we check the timbers and talk to building control before any such change.
When a repair is not enough, our pitched roofing page sets out how a complete re-cover is worked out, and our roof repairs page covers the smaller jobs that are far more common.
Once the fault is found, the quote is a single written figure after the survey, and our contractors do the work with the guarantee in writing for ten years on the workmanship.
