Scott has spent more than 36 years on Surrey roofs, and on a new roof replacement that length of time shows up in the parts you never see: whether the battens were graded, whether the fixings suit the exposure, whether the loft still breathes once the tiles are back on.
Key Takeaways
- Full strip and rebuild fixed to BS 5534, with ventilation set out to BS 5250 so the new roof does not rot from inside.
- Free survey, drone view where it helps, then one honest fixed price in writing with no obligation and no charge.
- If a repair will do instead of a replacement, we say so and quote the repair.
- A 25-year written workmanship guarantee, handed over before the team leaves.
Family-run, fully insured with Public Liability Insurance, and staffed by our own experienced local roofers rather than subcontracted strangers, which is the same standard behind all our roofer services Knaphill homeowners call us for.
Call 07428 300474 any hour, day, night or weekend, and a real person answers.
A new roof replacement in Knaphill means stripping the covering back, checking what the tiles have been hiding, and rebuilding the roof so it works as a whole system rather than a patched surface.

Full Roof Replacement
The awkward part of a full replacement is that nobody knows the true state of the roof until the coverings come off. Battens rot quietly. Rafter ends soften where old flashing has been leaking for years. Anyone quoting a full strip and recover without saying what happens if the timber underneath is poor is guessing, and the guess ends up on your bill later.
We say it up front. The survey looks at the roof from the ground, from the loft and, where the pitch or the height makes it sensible, from a drone. What we find goes into a fixed price in writing. If timber needs replacing we tell you before the scaffold goes up, not after.
Fixing is the part that decides whether a roof lasts. Every tile and slate is fixed to BS 5534, which sets out mechanical fixing and wind uplift resistance, so nothing is relying on gravity and mortar alone. Dry ridge and dry verge replace bedded mortar where mortar is the weak point. Ventilation is set out to BS 5250 so the new roof does not trap moisture in the loft and rot the timbers you have just paid for.
Scott has spent more than 36 years on Surrey roofs. He still answers the phone. That is the whole arrangement.

Re-Roofing and Refurbishment in Knaphill
Not every tired roof needs stripping. Some do. The honest answer depends on the age of the covering, the condition of the battens and how much of the roof is actually failing, and that answer is worth having before you commit to five figures of work.
Plenty of Knaphill roofs are sound tile on failed detail. Slipped tiles over a broken batten. Cracked flaunching on a chimney throwing water down one slope. Perished flashing at an abutment. If a repair will hold for years, we say so and quote the repair. We would rather do the small job properly than sell a roof nobody needs.
Where a re-roof is the right call, refurbishment usually takes in more than the tiles:
- New treated battens, breather membrane and mechanical fixings throughout
- Chimney repointing, flaunching and new lead flashing to Lead Sheet Association guidance
- Fascias, soffits and cladding renewed while the scaffold is standing
- Guttering replaced and sized to BS EN 12056 so the outlets cope with real rainfall
- Loft insulation upgraded where Approved Document L's 25% rule applies
That last point catches people out. Once you replace more than a quarter of a roof surface, the energy efficiency requirement comes into play, and it is cheaper and simpler to handle it as part of the job than to be told about it halfway through. We build it into the quote from the start.
No hard sell on coatings. We do not offer them as a substitute for a roof.
The same team covers new roof replacement services.

Emergency Roof Replacement in Knaphill
The problem with storm damage is that it does not wait for office hours, and the first job is not a new roof at all. It is stopping the water. A roof that has lost a section of covering in a gale needs making safe and watertight the same day, then replacing properly once the weather allows and the scaffold is up.
Call any hour and a real person answers. Not a call centre, not an answering service, not a callback tomorrow. Emergencies go to the front of the queue and the work is done by our own roofers, the same people who do the planned new roof replacement services, so the temporary fix is done by someone who understands what the permanent one needs to be.
Whether you are sat in Knaphill or over towards a new roof replacement in Woking, we cover the whole area, new roof replacement included.
Make safe first. Then rebuild it once.

Service Area and Response Times
Wide coverage claims are easy to type and harder to honour. Ours is deliberately local: Knaphill sits inside a Surrey patch that runs through Woking, Guildford, Cranleigh and the towns and villages across Surrey and the Wey Valley. That is close enough that a roofer can be on site quickly and come back without it being a production.
Coming back matters more than turning up. The 25-year written workmanship guarantee is handed over in writing before the team leaves, and it covers all roof work and repairs, not only new roofs. If something is not right inside those 25 years we return and put it right. A firm that intends to disappear does not put that on paper.
We are fully insured and hold Public Liability Insurance. The roofers on your roof are our own, never subcontracted strangers.

New Roof Installation
Most complaints about roof installation are about the run of the job, not the roof: the skip in the wrong place, nobody explaining what day the tiles land, mess left in the borders. Sequence fixes that. Here is how ours runs.
Call and first conversation
You ring, day, night or weekend, and speak to someone who works on roofs. We ask what you are seeing, how long it has been going on and what the property is. Sometimes that conversation alone tells you whether you are looking at a repair or a replacement.
Free survey
The roof is inspected properly: externally, from the loft where there is access, and by drone where a drone shows something a ladder cannot. No charge and no obligation. From Knaphill to a new roof replacement in Guildford, the same team covers the patch, new roof replacement included.
Fixed price in writing
One written price covering strip, disposal, battens, membrane, fixings, all the detail work and the leadwork. Not a day rate, not an estimate that grows. If a smaller repair will do, that is what we quote.
Installation and handover
Scaffold, strip, rebuild, detail, clear. The site is left tidy each day and swept properly at the end. The written guarantee is handed to you before the team leaves.

Roof Types and Systems
Roofs go wrong in different ways, so they get replaced in different ways. A pitched roof fails at the fixings, the battens and the details around chimneys and valleys. A flat roof fails at the laps, the upstands and the falls, and the usual culprit is water sitting where it was never meant to sit.
What we replace:
- Pitched roofing, tile and slate, stripped and rebuilt with mechanical fixing throughout
- Flat roofing in EPDM rubber, GRP fibreglass and felt or torch-on, designed to BS 6229 with falls that actually drain, including warm-roof upgrades
- Garage roofing, including asbestos-cement sheet roofs, which we assess and then advise on the safe compliant route under the Control of Asbestos Regulations 2012. We assess and advise. We do not carry out licensed removal
- Metal roofing, standing seam zinc and aluminium, box profile and metal tile sheet
- Chimney work, repointing, flaunching, flashing, partial and full rebuilds, pots and cowls
Cold flat roofs that were never ventilated are a common find on Knaphill extensions and garages. The condensation gets blamed on a leak. Rebuilding it as a warm roof solves the actual fault.

Materials and Finishes
Cheap materials are where a quote gets shaved without anyone noticing. Thin battens, short nails, plastic trims that go brittle in five summers. The saving is real and so is the second re-roof.
We specify to last. Graded treated battens. Fixings sized for the exposure of the site rather than whatever is in the van. Lead formed and dressed to Lead Sheet Association guidance instead of the mastic and flashing tape that gets used to hide a bad detail. Breather membranes chosen to suit the ventilation strategy, not just to fill the gap.
On finishes, the aim is a roof that looks like it belongs on the house. Tile and slate matched to the existing where you are replacing part of a terrace or a semi. Dry verge and ridge in a colour that does not shout. Seamless aluminium guttering where a long run would otherwise need joints, and joints are where gutters leak.
Roof cleaning, where it is wanted, is low-pressure soft wash and moss removal by hand. We do not pressure wash roofs. Pressure drives water under tiles and strips the surface off them, which turns a cleaning job into a re-roof.
Do it once. Do it properly. That is the offer.
