Honest advice
How to Tell You Need Roof Replacement
A re-roof is a big decision, so it is worth being sure the roof genuinely needs replacing rather than repairing.
Tiles lifting by hand or slipping repeatedly across several slopes (nail sickness)
Widespread cracked, delaminating or porous tiles
Sagging roofline or visible dips between rafters
Repeated repairs that no longer hold — money going in with no lasting fix
When it is not the answer: If the covering is sound and only the ridge mortar, a valley or some fixings have failed, replacement is an oversell — targeted repair is the right answer. Read the full guide.
How the detail works — the same principles we check on every Guildford roof.
Guildford homeowners tend to notice these signs earlier because wey Valley humidity around Bellfields and Shalford slows drying times and accelerates moss and mortar decay on the valley floor.
The process
From First Call to Sign-Off
1. Full survey & measure
We assess every slope, the underlay and the timbers, and measure for accurate materials.
2. Written itemised quote
Tile type, membrane, battens, scaffold and labour priced separately, with a stated allowance for any timber found on strip.
3. Scaffold & scheduling
We erect scaffold, arrange permits, and agree a start date and weather contingency.
4. Strip & re-roof
We strip the old covering, renew underlay and battens, and re-lay to BS 5534 with new fixings throughout.
5. Cleanup & guarantee
Full site clear, waste removed, and your written 10-year guarantee plus manufacturer warranties handed over.
In Guildford (GU1, GU2, GU3, GU4, GU5) we factor the local access into the plan from the first survey: guildford's steep town-centre streets and tight Victorian terraces off Stoughton Road mean rear-access scaffold and permit-controlled pavement space; the open-plot detached stock at Merrow scaffolds quickly by comparison.

Re-roofs are weather-dependent — we never leave a roof open overnight and phase the strip so the house stays watertight throughout.
For Guildford jobs we allow for local access around Quarry Street, Chapel Street when we schedule.
Access
Scaffold, Skips & Street Access
A full re-roof always needs scaffold for safe working and materials handling; it is itemised in the quote and we arrange it. Scaffold is specified for: the whole job — full perimeter scaffold with a loading bay - always itemised in your written quote, never a hidden extra, and we arrange it.
Guildford's steep town-centre streets and tight Victorian terraces off Stoughton Road mean rear-access scaffold and permit-controlled pavement space; the open-plot detached stock at Merrow scaffolds quickly by comparison. Pavement scaffold and skip permits go through Guildford Borough Council; allow a few working days on streets like Quarry Street, Chapel Street, The Mount where space is tight.
Guarantee
The Guarantee in Plain Terms
The complete re-roof carries a written 10-year workmanship guarantee, transferable if you sell; tiles and membrane add manufacturer warranties.
Covered: workmanship for 10 years, in writing, transferable if you sell.
On top: manufacturer warranties on materials (terms vary by product).
Not covered: storm or impact damage - that is an insurance matter, and we will document it for your claim.
If a fault appears in covered work, we come back and put it right. No quibbling, no re-charge.
Whether you are in the heart of Guildford or its edges, the guarantee and the standard are identical — in writing, transferable if you sell.
Good to know
What It Is Like While We Work
Scaffold goes up for the duration and there is skip and delivery activity; you do not need to be home, and we protect drives, borders and access daily. You do not need to stay home for external work - we just need power and access agreed in advance.
We strip in sections and sheet up each night; sustained rain or high wind can extend the programme, which we flag early. Wey Valley humidity around Bellfields and Shalford slows drying times and accelerates moss and mortar decay on the valley floor.

Guildford's housing splits cleanly by era. The post-war concrete-tile estates at Park Barn, Stoughton, Bellfields and Westborough take like-for-like concrete tile at the lower end of these ranges. The Victorian and Edwardian stock through the town centre fringes and Merrow was built in clay and, outside conservation constraints, is usually re-roofed in clay. The 1930s semis across Rydes Hill and Onslow Village fringe carry plain clay peg tile as the original covering.
Concrete tiles have a typical service life of around 40–50 years and natural slate and clay 60 years or more, so replacement timing should be judged against the covering's expected lifespan, not just its appearance.— NFRC technical guidance / BS 5534 roofing standard
Cost Drivers
What Pushes a Guildford Re-Roof Price Up or Down
Four variables move the price within these ranges more than any others in Guildford:
Conservation-area premium (+20–40%)
Properties in Shalford, Onslow Village, Artington, Compton, Bramley and the town-centre conservation areas must be re-roofed in matching materials to a standard the conservation officer will accept. Matching clay tile or natural slate, lime mortar bedding and like-for-like detailing add 20–40% over a standard concrete re-roof. This is a genuine cost, not an upsell — it is a planning requirement.
Access and scaffold
The narrow terraced streets off Stoughton Road and around the town centre restrict scaffold access and sometimes require a Guildford Borough Council pavement licence for the scaffold footprint. Detached properties on open plots at Merrow and Worplesdon are quicker to scaffold and price lower for access.
Structural findings on strip
Pre-1970 Guildford roofs frequently reveal deteriorated battens or the occasional rafter-end rot once the covering is off — particularly in the humid Wey Valley suburbs. A responsible quote carries a provisional allowance for this rather than adding it as a surprise mid-job.
Tile choice
Clay costs £1,500–£2,000 more than concrete on a standard semi but lasts 40–60% longer. On a conservation property the choice is made for you; elsewhere it is a genuine trade-off between upfront cost and lifespan.
To make the numbers concrete, here is a fully worked example for a typical property type in Guildford. A three-bedroom 1960s semi-detached on the Park Barn estate, concrete interlocking tile, showing nail sickness across two slopes and a failed ridge line.
Item
Cost
Scaffold (semi, both elevations)
£700–£900
Strip and dispose existing covering
£600–£800
New treated battens + breathable membrane
£700–£1,000
Concrete interlocking tiles (like-for-like)
£1,800–£2,400
Ridge — dry-fix system, mechanically fixed
£500–£800
Labour
£2,000–£3,000
New leadwork to abutments
£300–£600
Total
£6,600–£8,900
The same property specified in clay tile would run £8,000–£11,000. A comparable 1930s semi in a conservation part of Onslow Village, requiring matching clay peg tile and lime mortar, would sit at £10,000–£13,000 once the conservation premium is applied.
How We Price
What a Full Guildford Re-Roof Quote Should Contain
A quote you can trust itemises every element rather than presenting a single figure. On a Guildford re-roof, that means scaffold priced separately, the specific tile grade and manufacturer named, batten and counter-batten specification, breathable membrane, ridge system and mortar grade, valley and lead detailing, waste disposal, and labour. A lump-sum quote with none of this detail is the type that grows once the covering is off and "unexpected" costs appear.
We also carry a stated provisional allowance for batten or rafter replacement on pre-1970 properties, because Guildford's older stock frequently reveals deteriorated timber on strip — particularly in the damp Wey Valley suburbs. Flagging this in the quote as a defined allowance, rather than discovering it mid-job, is the difference between a price that holds and one that escalates. When you compare Guildford re-roof quotes, compare the specification first and the headline figure second: a cheaper quote that specifies concrete tile and cement mortar on a period clay property is not comparable to a correct one, and will cost you far more over the roof's life.
Timing & Value
When to Re-Roof and How It Protects a Guildford Sale
Timing a re-roof well saves money and protects value. The signs that replacement has overtaken repair are clear: nail sickness across more than one slope, repeated leaks from different points, sagging between rafters, and a covering past its material life — roughly 40–50 years for concrete tile, 60+ for clay. Left too long, a failing roof lets water reach battens, rafters and ceilings, turning a straightforward re-roof into a structural repair. Acting at the right point keeps the job to the covering alone. For anyone planning to sell in Guildford's competitive market, a new roof with a transferable written guarantee removes the single biggest deduction a surveyor can flag, and typically returns close to its full cost in the sale price.

FAQ
Frequently Asked Questions
A 3-bed semi costs £6,500–£9,000 in concrete tile, £8,000–£11,000 in clay tile, or £10,000–£14,000 in Welsh slate. Detached properties run £9,000–£20,000 depending on size and material. Conservation areas add 20–40%. Every quote is free and itemised.
The biggest single factor is usually the conservation-area premium — Shalford, Onslow Village and the town-centre areas require matching materials and lime mortar. Tile choice, roof pitch, access and structural findings on strip also move the price. A like-for-like scope comparison is the only fair way to compare quotes.
Yes — on a property with an end-of-life roof, a re-roof typically adds close to its full cost in value, because buyers and surveyors otherwise price in the replacement as a deduction. A RICS survey flags an aged roof as a liability; a new roof with a written guarantee removes that note.
Our quotes always list scaffold as a separate line — typically £700–£900 for a standard Guildford semi. Always check whether a quote includes scaffold, as it is frequently omitted from headline prices and added once work begins.
A standard 3-bed semi takes 3–5 working days including scaffold. Larger or conservation properties take longer. We keep the property watertight at the end of every working day regardless of progress.
Like-for-like replacement outside conservation areas needs no permission. Material changes, or any work in a conservation area, may require prior approval — and concrete substitution for clay is rarely approved in Guildford's conservation areas. We confirm the planning position during the survey.
All our re-roofs carry a written 10-year workmanship guarantee, transferable if you sell. Tile and membrane manufacturers provide their own product guarantees on top. Both are provided on completion.
Yes — we re-roof year round. Mortar-dependent work such as ridge bedding avoids sustained frost, but dry-fix ridge systems and membrane work continue through cold weather with the property kept watertight throughout.
