Expert Roof Replacement That Lasts a Generation
A roof replacement is the complete renewal of a roof's covering: stripping off the old slates or tiles, renewing the underlay and battens beneath, and recovering the whole roof so it's watertight for decades. A re-roof is the same job by another name. If you're considering a new roof in Cornwall, the real question isn't the slates on the surface, it's whether the structure beneath is sound and worth recovering, and getting that judgement right is where genuine expertise earns its place.
That's exactly where we start. Steve surveys the whole roof and structure properly and gives you an expert assessment of whether you genuinely need a full replacement now, or whether your roof has good years left in it. When a re-roof is the right investment, it's carried out to BS 5534 with the leadwork done by a specialist, built to last a generation, not just the season.

The Re-Roofs We Carry Out
From a straightforward house re-slate to a new-build roof from scratch, it is all covered:
Full re-slating & re-tiling
Stripping the old covering and recovering with natural slate, fibre-cement slate or tile, matched to your property and laid to BS 5534.
Re-felt & re-batten
A proper re-roof renews the underlay and battens beneath, not just the visible slates, so the whole system is sound from the structure up.
Flat-roof replacement
Stripping old felt and recovering in fibreglass (GRP) or EPDM rubber for a far longer-lasting, lower-maintenance result.
New-build & extension roofs
Roofing new houses, extensions and outbuildings from the rafters up, with all the lead detailing carried out by a specialist.
Period & listed re-roofs
Sympathetic recovering of traditional Cornish properties, with reclaimed or heritage slate where the building calls for it.

Decades of a dry, sound roof.A correctly laid slate roof lasts generations: do it once, do it right, and the roof looks after itself for a very long time.
No more chasing leaks.A re-roof renews the whole system, underlay, battens, flashings and covering, so the cycle of repeat repairs ends for good.
A warmer, drier home.A sound, properly felted roof keeps the weather out and the heat in, which makes a real difference through an exposed Cornish winter.
Real value in the property.A new roof is one of the few things a buyer or surveyor genuinely cares about: a sound, guaranteed roof removes a big question mark from the house, and ours is backed for 10 years.

Why choose us
Why Choose Us for Your Re-Roof
A re-roof is only as good as the detailing that goes with it, and that's where Steve's leadwork specialism pays off most. He's NVQ-qualified specifically in leadwork as well as roofing, so the valleys, chimney flashings and abutments on your new roof, the parts most roofs eventually leak at, are fitted to the highest standard as part of the build. All work follows BS 5534, the British Standard for slating and tiling, which sets out how slates, fixings and flashings must be specified to withstand the wind loads on Cornwall's exposed coastal roofs.
You're also in fully insured hands (public liability, employers' liability and hot-works cover) with over 10 years' experience across domestic, heritage and commercial roofs, proper scaffolding for safe access, a clean site with all waste removed, and a 10-year workmanship guarantee on the whole roof. The biggest job your roof will ever have, in genuinely expert hands.

About the Roofer, Steve Biggs
Roof replacements are carried out by Steve Biggs, owner of West Cornwall Roofing & Leadwork. Steve has over 10 years' roofing experience across Penzance and West Cornwall, and is NVQ-qualified in roofing and leadwork, holds a flat-roofing certificate and a CSCS card, and is certified in working at height and asbestos awareness. The leadwork NVQ, a separate qualification from general roofing, is what makes the detailing on his re-roofs stand the test of time.
“A re-roof is a big investment, so people deserve a straight, expert answer on whether they actually need one. When they do, it's done properly from the structure up: new felt, new battens, lead detailing to code, and the site left clean. That's the roof that lasts thirty or forty years and you forget about.”Steve Biggs, owner and lead roofer

How Our Re-Roofing Quotes Work
A roof replacement is too big a job to guess at, so an accurate price starts with a proper survey. What shapes a re-roofing quote is the size and pitch of the roof, the material you choose (natural slate, fibre-cement slate or tile), how accessible the roof is and what scaffolding it needs, the condition of the structure once the old covering is off, and how much lead detailing the roof calls for.
What you can always count on: a free survey, a clear written quote that sets out the materials and the scaffolding, and an expert recommendation on whether a full re-roof is genuinely the right answer for your roof right now. The scaffolding, the strip-out and full clearance of the old materials are all part of the job, set out in the quote, never sprung on you later.
Frequently asked questions
How do I know if I really need a new roof, or just repairs?+
The tell-tale signs are slates slipping, cracking or going missing across the whole roof, flaking or powdery slate, a sagging roofline, or leaks that keep returning. Once roughly a fifth or more of the covering is failing, a re-roof is usually better value than ongoing repairs. Steve surveys the roof free of charge and gives you a straight, expert recommendation either way.
How long does a re-roof take?+
Most re-roofs run from a few days to a couple of weeks, depending on the size and pitch of the roof, the weather, and how complex the detailing is. Steve gives you a realistic timescale with your written quote, so you know exactly what to expect before any work starts.
How much does a new roof cost?+
Every roof is different, so the accurate answer comes from a survey. The size, pitch, material, access, scaffolding and the condition of the structure underneath all shape the price. Steve surveys the roof free and gives you an exact written quote with everything set out and no hidden extras.
Do I need scaffolding for a re-roof?+
Yes, for almost all re-roofs. Scaffolding is the safe, code-correct way to strip and recover a whole roof. It is set out and included in your quote from the start, not added on partway through.
Will you clear away the old roof and leave the site tidy?+
Yes. Full clearance and waste removal of the old slates, felt and battens is part of the job, and the site is left clean and tidy at the end. You are not left with a skip of debris to sort out yourself.
Can you roof a new-build or extension?+
Yes. New-build and extension roofing is part of what we do, from the rafters up, including all the lead detailing around valleys, chimneys and abutments by an NVQ-qualified leadwork roofer. See our slate & tile roofing page for the coverings we fit.
