If you’ve started asking around about a new roof in Hertfordshire, you’ve probably noticed the quotes vary a lot. That’s normal, since a re-roof isn’t a single product with one price tag. Instead, it’s a job made up of scaffolding, stripping the old covering, replacing timber where needed, and fitting new materials. Each of those steps changes cost, depending on your roof.
This guide sets out what typically drives the price. That way, you’ll know what a fair quote should cover before you compare like with like.
What actually drives the cost
Three things move the price more than anything else: the size of the roof, the material you choose, and what’s found underneath once the old covering comes off.
Roof size is usually measured in square metres of covered area. Most trade cost guides price a straightforward re-roof per square metre. The total is then adjusted for pitch, access, and the number of chimneys, valleys and dormers that need extra detailing. Because of this, a simple, low-pitched roof on a semi-detached house is quicker and cheaper to strip and re-cover than a steep Victorian roof with several valleys, even if the two roofs cover a similar floor area.
Material is the next big factor. Concrete interlocking tiles sit at the affordable end. Clay tiles and natural slate cost more to buy and are slower to lay, and each has different labour needs. If slate is what you’re weighing up, our guide on how long a slate roof lasts explains why it commands a premium over concrete or clay.
Finally, what’s underneath matters. Roofs built before the 1990s often have timber that’s undersized by today’s building regulations, or battens that have rotted where felt has failed. However, a responsible roofer prices for likely repairs, but confirms the final figure once the old covering is off and the timber is visible. That’s one reason a written quote should always say what happens if extra work is found, rather than leaving it as a surprise on the invoice.
Typical price ranges
As a rough guide, UK trade cost guides commonly put a full re-roof on an average three-bedroom semi somewhere in the low-to-mid five figures for concrete tiles. This rises well beyond that for natural slate, or for a large detached property with a complex roofline. These figures move with material costs and labour rates, so treat them as a starting point for a chat, not a fixed price. The only true number is the one in a written quote for your actual roof.
Smaller jobs cost less overall, but rarely scale down in a straight line. That’s because scaffolding, skip hire and site set-up are largely fixed costs, whatever the roof size. As a result, two roofs of quite different sizes can end up closer in price than you’d expect.
Repair vs full replacement
Not every roof problem needs a full re-roof. If you’re seeing slipped tiles, a handful of leaks, or general wear rather than widespread failure, it’s worth reading our guide on whether to repair or replace before committing to the bigger job. In some cases, a partial repair or a re-cover of just the worst-affected slopes is the more sensible route. Our new roofs service page covers the full-replacement end of that decision.
Getting an accurate quote
A useful quote should set out the material specified, the area to be covered, what happens to existing flashing and guttering, and whether scaffolding and waste disposal are included. If a figure looks unusually low compared to others, ask exactly what’s left out. It’s often labour warranty, like-for-like flashing, or full scaffold access rather than a tower for spot repairs.
