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.

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.

Customer Reviews
Re-Roof Reviews from Guildford Homeowners
★★★★★
“Full re-roof on our Victorian property on Josephs Road — conservation area, clay tile replacement required. They sourced a genuine match, got it approved and completed the work in six days. Meticulous job, excellent cleanup.”
Patricia H. · Josephs Road, Guildford
★★★★★
“Our 1960s Park Barn house needed a complete strip and re-tile — the concrete tiles had reached end of life. Clear quote, no surprises, done in five days. The new Marley Modern tiles look excellent.”
Graham F. · Park Barn, Guildford
★★★★★
“Obtained four quotes for our Merrow detached property re-roof. Guildford Roofing were third on price but the most thorough in their survey — they found sarking problems the others missed. Glad we went with them.”
Nail sickness: corroded fixings let sound slates slip
FAQ
Roof Replacement Questions
A standard 3-bed semi in Guildford costs between £6,500–£10,000 for a full re-roof, depending on size, pitch and materials. Properties requiring conservation-grade clay tiles can add 15–25% to material costs. Larger detached houses typically run £10,000–£15,000. We provide a free full survey and itemised quote before any commitment.
Yes. We specialise in this. Guildford's historic centre has strict requirements for maintaining original clay tile profiles. We source matching tiles from specialist manufacturers and can use reclaimed stock for listed buildings. The match process starts with identifying your original tile — bring us a sample and we'll advise.
A 3-bed semi typically takes 4–6 days. Larger detached properties with complex hips, valleys and dormers can take 8–12 days. We give you a realistic programme in the quote and keep you updated throughout. Conservation area work occasionally has longer lead times due to tile sourcing.
Generally no — like-for-like replacement is permitted development. However, if your property is in a conservation area or is listed, you'll need approval to change materials. We know Guildford's conservation area boundaries well and will flag this during the survey if it applies to your property.
For like-for-like replacement in the same material, planning permission is not typically required. Conservation area properties and listed buildings may need prior approval or Listed Building Consent. We advise on planning position during the survey visit.
A re-roof creates noise and requires scaffold but does not require you to vacate. We clear all debris at the end of each working day and maintain access throughout. Most Guildford re-roofs are completed in 3-5 working days.
Major manufacturers such as Marley and Sandtoft offer 30-year product guarantees on clay and concrete tiles, in addition to our 10-year workmanship guarantee. These transfer with the property if you sell.

Re-Roofing Guildford Properties — What the Process Involves
A complete re-roof on a standard Guildford semi-detached property takes 3–5 working days and follows a defined sequence. Day 1: scaffold erected to full height on all elevations requiring tile removal. Day 1–2: existing tile covering stripped from all slopes simultaneously to reveal the batten, underlay and rafter structure beneath. Battens and underlay replaced as standard; rafter condition inspected and any deteriorated sections replaced before new covering begins. Day 2–4: new breathable membrane counter-batted, new tile batten installed to correct gauge, and new tile covering laid from eaves to ridge on all slopes. Day 4–5: ridge bedded and mechanically fixed, any lead work completed, gutters reconnected and scaffold cleared. The property is kept fully watertight at the end of every working day throughout this sequence — we do not leave exposed underlay overnight if any rainfall is forecast.
The material decisions in a Guildford re-roof — tile type, ridge profile, mortar specification — are determined by the property age, location and planning position, not by material availability. For pre-1950 Guildford properties, clay tile in the original profile is the correct specification in most cases, subject to conservation area requirements where applicable. For post-war concrete tile properties, like-for-like concrete tile replacement is typically appropriate and more economical. We do not sell the more expensive option where the less expensive option is the correct specification — and we confirm the planning position for every property before the material recommendation is made.
What the Survey Establishes Before We Quote
Our re-roof surveys always include a loft inspection as well as ridge-level access. The loft inspection establishes: the condition of the existing underlay (which may affect whether the new installation can proceed without full strip in all areas or whether some areas can be over-battened); rafter and purlin condition and any structural concerns; the presence and condition of any existing insulation and its effect on ventilation requirements; and any evidence of past water ingress that might indicate areas requiring additional attention. The survey report includes a risk assessment of findings that might affect the job scope — presented before the quote is agreed rather than discovered during the job.
