Asbestos Roof Waterproofing In Reading — Gaco Cold-Applied Coating System

Yes. Duratite covers all of Reading and the wider the Thames Valley area for commercial asbestos roof waterproofing. Our manufacturer-trained applicators install the Gaco cold-applied silicone coating system across commercial, industrial and agricultural asbestos cement roofs.

For most Reading postcodes we attend within 2-5 working days of enquiry. Urgent surveys can be arranged within 48-72 hours. Each visit includes a roof walk-over, photographic record of failure points, drainage assessment and same-week written quote with no obligation.

For commercial work in Reading, the Gaco cold-applied system typically ranges from £20 to £40 per square metre supplied and installed depending on the build-up. The acrylic-only route (U-series + S42 / SF42) is at the lower end; a heavier build-up over damaged or uneven sheets sits at the upper end. Final pricing depends on roof condition, access and area. Free site survey provides an exact figure with no obligation.

Properly specified and installed, a Gaco S42 / SF42 silicone topcoat over the right primer extends the useful life of an asbestos cement roof by 20+ years and is backed by a 20-year manufacturer-backed product warranty. The system stays UV-stable, remains highly reflective, and can be re-coated at end of life rather than stripped.

Cold-applied Gaco silicone needs a dry substrate above approximately 4°C with no rain forecast in the curing window — broadly March to November in Reading. We monitor the Met Office forecast for your postcode and will only break in once the window is reliable. The acrylic primer flashes off in 1-2 hours, the silicone topcoat cures in 4-8 hours, and the system tolerates light moisture once cured.

Strip-and-recover means full asbestos removal under HSE-licensed conditions, scaffolding, weather sheeting and a brand-new roof — typically £80-£150/m² and weeks of disruption. Coating means leaving the asbestos in place, sealing it from above with the Gaco system at £20-£40/m² in days, with no disturbance and no waste-stream cost. Coating is right when the asbestos is sound but the roof is leaking or weathering. Free site survey to confirm the right route.

Yes. Gaco S42 / SF42 silicone is fully recoatable at end of life — typically 20+ years from installation — by spec'ing a thin maintenance coat over the existing one. No strip, no waste, no scaffolding penalty. We document the build-up so any future contractor can pick up the system.

Yes. The 20-year warranty is a manufacturer-backed product warranty issued by Amrize on the Gaco system, valid only when the installation is completed by Duratite-approved manufacturer-trained applicators. The full compliance dossier — datasheets, installer accreditation, photographic record and warranty certificate — is handed over at project completion.

We regularly work across Green Park, Thames Valley Park, Reading International, Worton Grange — and every other commercial estate in and around Reading. If your building sits outside these areas we still cover all of the Thames Valley; call 01208 832 602 to confirm your postcode.

Yes. The same approved contractor network that covers Reading works across the whole of the Thames Valley, including Basingstoke, High Wycombe, Slough. One survey team, one specification, one 20-year manufacturer-backed product warranty — wherever the building is.

The coating is applied by approved contractors trained on the Gaco system, with full public liability insurance, CSCS-qualified operatives and safe roof-access protocols — all cold-applied, so no hot works permit is needed. The products are supplied by Duratite Building Products Limited and manufactured by Amrize, and the 20-year product warranty is manufacturer-backed and valid only when an approved applicator completes the install, which is exactly how every Duratite-managed project runs.
