What drives roofing prices in Wales

Labour is the largest part of a re-roof, so local pay matters: Wales ranks 9th of 12 regions and nations on median full-time weekly pay.

For any single house, size and shape matter more: every extra square of roof adds materials and labour, hips and valleys add cutting and waste, and steep pitches need staging and fall protection. Tearing off more than one old layer, replacing rotten decking, and difficult access all add to the quote.

Why do roofing prices in Wales differ from other regions and nations?

Labour is roughly 60% of a re-roof, so local pay drives most of the difference. Wales ranks 9th of 12 regions and nations for median full-time weekly pay (£719/week). Roof size, pitch, tear-off, access and material choice still matter more than location for any single job.

Does roof pitch change the cost?

Yes, in two ways. A steeper roof has more surface area for the same footprint (a 6/12 roof is 11.8% larger than its footprint, a 12/12 roof 41.4% larger), and roofs steeper than about 7/12 need staging and fall protection, which most contractors price as a steep-slope surcharge.

How these estimates work

Estimates start from published United Kingdom installed-price ranges, which describe the UK overall. Labour is about 60% of a re-roof, so each region's range is multiplied by 0.4 + 0.6 × (local median full-time weekly pay ÷ the United Kingdom figure). Totals are rounded to the nearest 100. Prices are GBP. They are estimates for budgeting, not quotes: tear-off layers, decking repairs, access, permits and roof complexity can move a real quote well outside the range.
