The short answer
National guides give typical ranges by roof shape, from about £5,000 to £8,000 for a gable-roofed semi-detached house to £8,000 to £12,000 for a hipped one. Roof size, covering and access shift the figure, and the survey is what settles the price in writing.
Upper Stratton is not in a conservation area, so choosing a covering is a question of taste, budget and the roof structure, and not of permission. That makes the cost the practical issue.
Q3.1What are the typical national ranges?
MyBuilder's roof replacement guide, updated on 21 August 2026, gives ranges for a semi-detached house of 50 to 80 square metres: £5,000 to £8,000 with a gable roof, £8,000 to £12,000 hipped, £2,500 to £6,000 flat and £3,000 to £5,500 for a lean-to. These are typical UK figures, not our prices.
Q3.2What moves the price?
A handful of things push a quote up or down, and it helps to know them before the survey. The roof's area and shape matter most, because hips and valleys add cutting and labour. The covering comes second, with clay and natural slate above concrete. The condition of the battens and timbers underneath can add repair work once the old tiles come off. Access and scaffold complete the list. Our roof replacement page explains the process.
Q3.3Do permission or weight rules apply?
No conservation area applies here, so a replacement covering does not need design approval. Building Regulations come into play once the work reaches 25 per cent of the building envelope or 50 per cent of the roof, or if the new covering adds 15 per cent or more to the weight. Swindon Borough Council runs its own building control, and the notification is something we deal with when it applies.
Whoever you choose, make sure every price you are offered allows for scaffold, stripping, underlay, battens, tiles, clearance and VAT. Only then are two prices honestly comparable.
