Why Coat Instead of Strip
Why waterproof rather than strip a Liverpool commercial building asbestos roof?
Asbestos cement is at its most dangerous when it is disturbed — and at its most expensive when it is removed. The Gaco cold-applied silicone system takes the opposite route: non-abrasive preparation, priming, fibre-reinforced over-banding of every lap and fixing, then a seamless silicone topcoat — all applied from above the roof, outside the building.
One team specifies, supplies and supervises the whole job: Duratite issue the specification, the system is installed by manufacturer-trained approved contractors covering every Liverpool postcode, and the finished roof is backed by a 20-year manufacturer-backed product warranty — with completion records for your asbestos management plan. We regularly survey and coat roofs around Speke, Aintree, Bootle.
- ✓No strip-and-recover, no licensed removal, no hazardous waste stream
- ✓No fibre disturbance — cold-applied from above, no cutting or drilling
- ✓Works phased around trading hours and customer footfall — the building stays occupied
- ✓Often eligible for Land Remediation Relief on qualifying expenditure
Seal or Strip?
Does your Liverpool asbestos roof need stripping — or just sealing?
Strip-and-recover is the right call for structurally failed sheets — and only then. For the far more common case of weathered-but-intact asbestos cement, cold-applied silicone stops the leaks, locks the fibres in and costs a fraction of the strip route. The free Liverpool survey assesses sheet condition honestly and puts the answer in writing.
Tick two or more and coating is very likely your route — the free Liverpool survey confirms it either way, in writing.

Budget & Pricing
How much does asbestos roof waterproofing cost in Liverpool?
The complete Gaco cold-applied silicone system on a Liverpool commercial building roof typically costs £20 to £40 per m² fully installed — one figure covering materials and professional application. Sheet condition, access and detail density set where you land in the range.
| Route | Typical price | What it involves |
|---|---|---|
| Gaco silicone system — fully installed | £20–£40 / m² installed | Sheets sealed from above: preparation, priming, over-banding, silicone topcoat, warranty |
| Strip-and-recover (for comparison) | £80–£150 / m² | Licensed removal, sheeting drops, waste disposal, then an entire new roof covering |
| Typical approach with coating | Coated in place, no tear-off | Plus zero downtimetrading hours and customer footfall continue underneath throughout |
Every coating figure above is a fully installed price — materials, professional application by Gaco-approved contractors and the manufacturer-backed warranty option are all in the number. There is nothing to add for labour, and the expenditure is often LRR-eligible. A free Liverpool survey turns the range into one fixed written figure the same week.
What the installed price includes
One system, one price. Every component below is part of the installed figure — none of them is ever priced separately.
✓Non-abrasive surface preparation (no fibre disturbance)
✓Repairs and priming to survey findings
✓Fibre-reinforced over-banding of laps, fixings & ridge details
✓Silicone topcoat to the warranted film build
✓Edge and penetration detailing
✓Completion records for the asbestos register + 20-year warranty issue
The Bottom Line
Coating a Liverpool asbestos roof costs a fraction of stripping it
70%maximum saving vs strip-and-recover
No licensed removalNo waste streamNo closure days
Where the saving actually comes from
A strip-and-recover pays three times: licensed asbestos works with notification and controls, disposal of a hazardous waste stream, and then an entire new roof covering over an exposed frame. Coating skips all three — the existing sheets stay put and become the substrate for the new weather-tight surface.
The unpriced saving matters just as much: trading hours and customer footfall continue underneath throughout, so there is no lost output, no decant and no temporary space to pay for.
✓Free site survey and written quotation — no obligation
✓Installed by Duratite-approved, manufacturer-trained applicators
✓One point of contact from survey through to sign-off
Head to Head
Coating vs strip-and-recover for a Liverpool commercial building roof
The same roof, two very different routes. This is the comparison every Liverpool dutyholder should see before signing a strip-and-recover order.
| What it means for you | Gaco silicone system | Strip-and-recover |
|---|---|---|
| Typical cost | £20–£40 / m² fully installed | £80–£150 / m² |
| Fibre risk during works | None — sheets sealed, not disturbed | Managed but real — full licensed controls needed |
| Regulatory burden | CAR 2012 in-situ management, records supplied | Notification, licensed contractor, waste consignment |
| Time on site | Days — sections weather-tight same day | Weeks — strip, dispose, rebuild |
| Impact on trading hours and customer footfall | None — the building stays live | Decant or shutdown for the programme |
| Warranty | 20-year manufacturer-backed product warranty | Varies by system and installer |
The honest caveat: coating cannot rescue structurally failed sheets. That’s exactly what the free Liverpool survey establishes before any money changes hands — and if strip-and-recover is genuinely the right answer, the report says so.

Your Questions Answered
Liverpool Commercial Building Asbestos Roof Waterproofing FAQ
Straight answers to the questions Liverpool commercial building operators and dutyholders ask us most.
Can you waterproof a Liverpool commercial building asbestos roof without removing it?
Yes — that is exactly what the Gaco cold-applied silicone system is for. The whole installation happens from above the roof and outside the building: non-abrasive preparation, priming, fibre-reinforced over-banding of laps and fixings, then the seamless silicone topcoat. No strip-and-recover, no licensed removal, no fibre disturbance — and trading hours and customer footfall continue underneath throughout.
How much does commercial building asbestos roof waterproofing cost in Liverpool?
The complete Gaco silicone system on a Liverpool commercial building asbestos roof typically costs £20–£40 per m² fully installed — materials and professional application in one figure. A strip-and-recover of the same roof typically runs £80–£150 per m² once licensed removal, waste and the new covering are counted. A free survey turns the range into one fixed written figure.
Is it safe to coat over asbestos cement — and is it CAR 2012 compliant?
Yes. The system is applied from the safe side of the roof with no cutting, drilling or abrasion, so fibres are not disturbed and no HSE notification is required for the coating works themselves. Sealing and managing asbestos cement in place is an accepted in-situ management route under the Control of Asbestos Regulations 2012 — we supply the records your asbestos management plan and register need.
Will the works disrupt our trading hours and customer footfall?
No. There is no flame, no hot air and no internal scaffolding — the coating is cold-applied externally. Works are phased around trading hours and customer footfall, with weekend and out-of-hours slots routine across Liverpool. Each roof section is weather-tight the same day it is coated.
When in the year can the system be installed in Liverpool?
Most of it. The primer flashes off in around 1–2 hours and the silicone topcoat cures in 4–8 hours, so installs run in dry weather windows across spring, summer and autumn — and in settled winter spells. The programme is sequenced section by section so the roof is never left exposed overnight.
How long will the coated roof last — and what warranty backs it?
The finished roof carries a 20-year manufacturer-backed product warranty from Gaco (Amrize) when installed by a Duratite-approved applicator. Silicone is UV-stable and rated for ponding water — and at end of term a thin maintenance coat extends the life again, still without ever disturbing the sheets.
Can the work qualify for Land Remediation Relief?
Often, yes. Dealing with asbestos on a commercial building is frequently eligible for Land Remediation Relief — typically a 150% deduction from corporation tax for qualifying remediation expenditure. We provide the project documentation your accountant needs; your tax adviser confirms eligibility for your circumstances.
Do you cover the wider Merseyside region as well as Liverpool?
Yes. The approved contractor network that covers Liverpool works across the whole of Merseyside. One survey team, one specification, one 20-year manufacturer-backed product warranty — wherever the commercial building building is.
Who installs the system in Liverpool — and who backs the warranty?
Installation is carried out by Gaco-approved contractors with manufacturer training, asbestos awareness training, full public liability insurance and CSCS-qualified operatives. The products are supplied by Duratite Building Products Limited, and the 20-year product warranty is manufacturer-backed by Gaco (Amrize) — only valid when an approved applicator completes the install, which is exactly how every Duratite-managed project runs.
