What This Guide Covers
New roof costs vary hugely depending on the size, pitch, material and condition of your existing roof - there's no single number that applies to every home. This guide breaks down the main factors that affect price, gives realistic UK-average cost ranges by roof type, and explains how to get an accurate, no-obligation quote.
The figures below are general guide prices to help you budget and compare - not a quote for your specific home. Every roof is different, which is why every job we price is based on a free, in-person survey.
If you’d rather skip straight to a proper price for your own roof, get in touch and we’ll arrange a free survey and written, itemised quote.
What Affects the Cost of a New Roof
The main factors that push a quote up or down.
Roof Size
The single biggest factor - a larger roof area means more materials and more labour.
Roof Pitch & Access
Steep roofs, tricky access and the need for scaffolding all add to the cost.
Material Choice
Concrete tile, natural slate, clay tile and flat roofing systems all sit at different price points.
Condition of the Structure
Rotten timbers or damaged decking found during the strip-off add to the job.
Scaffolding Requirements
Scaffold cost depends on roof height, access and how long it's needed on site.
Removal & Waste Disposal
Stripping off and disposing of the old roof covering is priced into every quote.
Number of Roof Features
Chimneys, valleys, dormers and skylights all add time and materials.
Time of Year
Demand and weather can affect pricing and availability at busy times of year.
