Seal a leaking industrial roof for a fraction of replacement cost. Complete GacoFlex silicone system from £15.50/m² fully installed — surveyed, coated and warranted by one team, without closing the building.
Industrial sheds in Staffordshire tend to fail at the details first: laps, fixings, cut edges, gutters. Gaco S42 silicone seals all of them into one membrane over the roof you already have, with SF42 fibre-reinforced where water lies.
One team specifies, supplies and supervises the whole job: Duratite issue the specification, the coating is installed by manufacturer-trained approved contractors covering every Cannock postcode, and the finished roof is backed by a 20-year manufacturer-backed product warranty.
A Cannock survey covers every Cannock postcode, with the balance of Staffordshire on the same rota. The same team covers Walsall and Wolverhampton on the same visit schedule.
Real completed GacoFlex silicone installs by the Duratite approved-installer network — the same system we specify in Cannock.
A tired profiled metal roof coated in place with Gaco S42 — no tear-off, no closure days, every seam, lap and fixing sealed under one continuous membrane. Real drone photography of a completed UK install.
The surface fails long before the structure does. If the deck under your Cannock roof is sound, the waterproofing can be renewed on top of it with no tear-off, and the building stays in use throughout. Where replacement really is the better call, the survey report says so.
Leaks at laps, fixings or rooflights — but the deck still feels solid underfoot
Corroding or chalking metal sheets, or weathered asbestos cement
Ponding water that sits for days after rain
Replacement quotes that blow the maintenance budget
Production lines underneath that cannot stop for a strip-and-re-sheet programme
A complete GacoFlex silicone roof coating system in Cannock typically costs £15.50 to £35 per m² fully installed — one figure covering materials and professional application. Roof condition, access and warranty length set where you land in the range.
| Complete system, fully installed | Typical installed price | Best suited to |
|---|---|---|
| GacoFlex system — 10-year specification | £15.50–£20 / m² installed | Sound roofs needing renewed waterproofing on a tighter budget |
| GacoFlex system — 20-year specification | £20–£25 / m² installed | Full film build for the 20-year manufacturer-backed warranty |
| GacoFlex system — complex roofs | £25–£35 / m² installed | Heavy preparation, chronic ponding, extensive seam & detail work |
| Full roof replacement (for comparison) | £80–£150+ / m² | End-of-life decks only — coating avoids this cost in most cases |
One system, one price. Every component below is part of the installed figure — none of them is ever priced separately.
You pay for the old roof twice in a replacement: once to remove and tip it, once to build its successor. Overcoating keeps the existing build-up as the base, so the bill covers the new membrane and the application, and nothing else.
That is also why the programme is measured in days rather than weeks, with no weather-exposed deck at any point.
The same cold-applied silicone sits on 1,000+ UK commercial projects — industrial units, estates, asbestos cement, corroding metal and ponding flat roofs — all done without tear-off.
The same roof, two very different routes. This is the comparison every Cannock building owner should see before signing a re-roof order.
| What it means for you | GacoFlex coating system | Full roof replacement |
|---|---|---|
| Typical cost | £15.50–£35 / m² fully installed | £80–£150+ / m² |
| Time on site | Days — weekend phasing routine | Weeks of strip-off and rebuild |
| Disruption below the roof | None — the building stays live | Weeks of strip-off over live production areas |
| Waste to landfill | None — the existing roof stays put | The entire old roof, skipped and tipped |
| Weather exposure during works | Rain-resistant within hours | Open deck between strip and re-sheet |
| Warranty | 20-year manufacturer-backed product warranty | Varies by system and installer |
| When it’s the right call | Sound deck, worn-out surface — most roofs we survey | Genuinely end-of-life decks and structures |
Restore industrial roofs across Cannock without overcladding or operational downtime. Gaco S42 single-coat silicone (and SF42 fibre-reinforced for ponding-prone areas) seal failing profiled metal, asbestos cement and bitumen — backed by a 20-year manufacturer-backed product warranty.
Days on site, not weeks. The coating is applied cold straight over the existing covering, so there are no skips in the yard, no closure days and no decant.
Backed directly by Gaco / Amrize on every approved-applicator install, and transferable if the building is sold.
Class A fire rating, solar reflectance up to 0.91, independently lab-tested for adhesion, elongation and UV stability.
Manufacturer-trained installers covering every Cannock postcode. One team specs, supplies and supervises — a single point of contact end-to-end.
Four steps from first call to 20-year warranty. Most Cannock roofs are surveyed within 2–5 working days and coated in days, not weeks.
A measured walk-over of your Cannock roof with photographic condition record — core moisture checks where needed.
Same-week quotation with measured areas, system build-up (S42 or SF42), warranty term and programme.
Preparation first — clean, repair, prime — then a cold application by spray, brush or roller. Nothing is heated, and the coating shrugs off rain within hours.
Final inspection, then the 20-year manufacturer-backed product warranty is issued on completion.
The same stages every GacoFlex install goes through — real UK roofs, no renders and no stock photography.
Failed asphalt, ponding water and leaking details — the classic candidate roof. If the deck is sound, this is exactly the roof a coating rescues.
Cleaned, repaired and detailed first — seams, laps and fixings banded in silicone before any field coat goes on. This is the detail work the 20-year warranty depends on.
The finished S42 membrane — one seamless, ponding-water-rated surface, self-terminating around lanterns and upstands, with the manufacturer-backed warranty issued on completion.
Duratite specifies all three Gaco coating chemistries. Use this side-by-side to shortlist — the free Cannock survey confirms the right build-up.

Gaco S42 carries a 20-year manufacturer-backed product warranty when installed by a Duratite-approved applicator in Cannock. The warranty is transferable on sale of the building, and remains valid for the full term provided routine inspections are carried out.
Gaco SF42 is the fibre-reinforced silicone — choose it for Cannock roofs with chronic ponding water, dished gutters or substrates needing extra crack-bridging.
