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.
Most Gateshead industrial roofs that leak do not need replacing. Profiled metal, asbestos cement and built-up felt can all be overcoated in situ with Gaco S42 single-coat silicone (or SF42 fibre-reinforced where ponding water sits), sealing every lap, fixing and cut edge in one seamless membrane.
The specification comes from Duratite, the material is supplied by Duratite, and the application is carried out by manufacturer-trained approved contractors working in Gateshead - finished under a 20-year manufacturer-backed product warranty. Expect industrial units and factory sheds, distribution and warehouse space and offices, retail and mixed-use stock on a Gateshead round, and a single cold-applied system across all of them. Surveys come back most often from Team Valley, Felling and Gateshead International Business Centre and the wider Gateshead estate network.
We survey the NE8–NE11 postcodes, and the rest of Tyne and Wear is covered by the same contractors. The same team covers Newcastle upon Tyne, South Shields and Tynemouth on the same visit schedule.
Real completed GacoFlex silicone installs by the Duratite approved-installer network — the same system we specify in Gateshead.
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.
Most “failed” commercial roofs have a sound deck under a worn-out surface. Replacement is only the right call when the structure itself has gone. If the deck is solid, a coating renews the waterproofing with no tear-off — and the building never closes. Where the two routes genuinely compete, we say so in the survey report.
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 Gateshead 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.
Strip-out, disposal, then a rebuild over an open deck — that is where replacement money goes, and none of it buys waterproofing. A coating leaves the existing roof in place and puts the budget into the membrane that keeps water out.
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 Gateshead 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 Gateshead 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.
S42 goes on cold and over the top, so the roof is done in days. Phase it across weekends and the building never loses a trading day — nothing stripped, nothing skipped out.
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 Gateshead 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 Gateshead roofs are surveyed within 2–5 working days and coated in days, not weeks.
A measured walk-over of your Gateshead 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.
