New roofs and re-roofing are the biggest job we take on, and across Chesterfield and north Derbyshire they're usually the right answer when a roof has simply reached the end of its life. A tiled roof does 40 to 60 years; a slate roof can do a century. When that time is up, no amount of patching puts it right for long.
When a Re-Roof Beats Repeated Repairs
There's a tipping point where a roof stops being worth repairing. If you're calling someone out every few months for a new leak, the problem isn't the individual tiles — it's the whole covering, the felt underneath, or the nails holding the slate on. Patching a roof in that state is money down the drain, because the next failure is never far away.
The Victorian terraces across Chesterfield's centre and the post-war semis through Clay Cross, Hasland and Newbold are now well into the age where the original covering and the bitumen felt beneath it have had their day. On slate roofs of that age the nails rust through and slates start sliding — what roofers call nail fatigue. On concrete tiles, the surface breaks down and begins to absorb water. On older felt, it's perished and split long before you see it from inside.
If you're seeing leaks in more than one place, if the felt in the loft is hanging in shreds, or if the roofline is starting to dip between the rafters, a full re-roof is almost always cheaper in the long run than another round of repairs. We'll tell you honestly either way — we don't sell re-roofs that aren't needed, and we don't pretend a repair will hold when it won't.
The covering you choose depends on the property, the pitch and the budget. Concrete interlocking tiles are the sensible default for most post-war homes — durable, affordable and quick to lay. Clay plain tiles suit period property and look right on the older terraces, whether new or reclaimed to match what's there.
Natural slate — Welsh or Spanish — is the long-life choice for pitched roofs and looks at home on Victorian and Edwardian stock. Fibre cement slate is the budget alternative that gives a slate look at a lower cost, with a shorter lifespan. On older Peak-fringe property, stone slate is what the building was built with and what it should be re-laid with.
Underneath it all, we use a breathable membrane rather than the old bitumen felt. Felt perishes, tears and traps moisture; a breathable membrane lets the roof breathe, cuts condensation in the loft and sheds wind-driven rain. It's one of the reasons a modern re-roof outlasts the one it replaces. We also re-bed ridges in mortar and dress code lead flashings at every chimney and abutment rather than relying on mortar fillets.
A full re-roof is notifiable work under Building Regulations, and we make sure the job meets Part L on insulation where the roof structure allows. We'll talk you through what that means in plain English before we start.
Every re-roof is priced on what's actually there — the size and pitch, the covering you choose, the condition of the timbers once we strip it, and whether scaffolding is straightforward or awkward. As a rough guide across north Derbyshire, a typical three-bedroom semi re-roof in concrete interlocking tile runs from around £5,000 to £7,500. Move to clay plain tile and you're closer to £7,000 to £10,000. Natural slate pushes higher again because the material and the labour both cost more.
Scaffolding is a real part of that price and we include it in the written quote — we don't quote a number then add the scaffold on after. Timber replacement, if the rafters are rotten, is the one thing that can only be confirmed once the old covering is off, and we show you what we've found before we replace it. The honest version is this: the covering sets the floor of the price, the condition of what's underneath sets the ceiling, and you get the full picture in writing before any work starts.
