Complete Roof Replacement

Stripped to the timbers and rebuilt to last the next fifty years and more.

A complete roof replacement strips everything back to the rafters and rebuilds the roof as a system: timber repairs where needed, a modern breathable membrane, fresh treated battens, the new covering, and correctly detailed ridges, verges, valleys, flashings and ventilation. It's the most thorough thing you can do to a roof — and done once, done properly, it's a fifty-year-plus decision for tile and longer for slate.

Replacement is the right call when the covering has failed as a whole: tiles shedding their surface across every slope, underfelt that has gone brittle and torn, fixings failing en masse, or a repair history that reads like a subscription. It's emphatically the wrong call when a roof has one local fault — which is why we inspect and will happily tell you a repair is all you need, when it is.

Because the scaffold is up and the roof is open, replacement is also the economical moment for everything else up there: chimney repointing and flashings, fascias and gutters, insulation top-ups and proper loft ventilation. We'll flag what's worth adding and what isn't.

Typical lifespan

50+ years

Concrete tile: 40–50 years. Clay tile: 60+. Natural slate: comfortably beyond 80 when well fixed. The membrane, battens and fixings we use are specified to match — the goal is a roof whose parts age together rather than one component failing decades early.

Repair options

Repair or replace

The honest test: add up what you've spent and are likely to keep spending on repairs, and set it against replacement once. One leak doesn't justify a new roof; a covering failing everywhere doesn't justify another patch. Our guide to repair versus replacement covers the judgement in detail, and our inspection gives you the specific answer for your roof — either way.

Our process

How we do it

Inspection and measured survey first, then an itemised quotation. On the job: scaffold up, roof stripped in sections and felted weathertight each day, timbers checked and repaired, membrane and battens on, covering laid, details finished, site cleared. A typical house takes one to two weeks. You'll get photographs at each stage — most of this work you'd otherwise never see.

Common questions

Frequently asked

How much does a new roof cost? +

For a typical UK semi, replacement generally runs from several thousand pounds to five figures depending on covering, roof complexity and access — slate at the upper end, concrete tile at the lower. Rather than a number plucked from the air, see our cost guide in the Advice Centre and get an itemised quotation for your actual roof; anything else is guesswork.

Will you find extra costs once the roof is off? +

The honest answer: sometimes — hidden rot only shows once stripped. We minimise surprises by inspecting thoroughly first, pricing foreseeable timber work in the quotation, and agreeing any genuinely unforeseeable work with you at cost before doing it. No silent extras on the final bill.

Can I live in the house during the work? +

Yes — replacement happens entirely outside the living space. Expect scaffold, some noise, and dust in the loft (cover stored items). The roof is never left open overnight.
