We survey the leak free of charge, then seal the whole roof with a seamless GacoFlex silicone membrane — no tear-off, no closing the building, backed by a 20-year manufacturer-backed product warranty.
Seamless GacoFlex membraneNo tear-off — building stays open
GacoPatch instant-cure silicone gives a targeted emergency repair that can be applied in wet or dry conditions — even during active rainfall. It makes the leak watertight the day it’s applied, while we survey, specify and price the permanent repair.
Almost every commercial roof leak starts at a joint — laps, seams, fixings, sheet ends and details, not the middle of the sheet. Patching one failure point leaves hundreds of identical ones untouched.
Joints, laps and mechanical fixings are exactly the points where commercial roofs leak — water tracks through the same weak spots on every sheet.
Exposed edges of profiled metal sheets lose their factory coating, letting moisture corrode the metal at lap joints and sheet ends. Left untreated it causes persistent leaks and structural damage.
Standing water finds every weakness. Felt and organic coatings soften, crack and delaminate under permanent puddles — silicone is the exception.
GacoFlex liquid waterproofing is cold-applied straight onto your existing roof — rolled, brushed or sprayed — and cures into a seamless, fully-bonded elastomeric membrane with no joints, laps or mechanical fixings. It seals exactly the points where commercial roofs leak, across the entire roof.
The system bonds to metal, felt, single-ply, concrete and asbestos-cement substrates, so there is no tear-off, no re-sheeting and no need to close the building while the repair is done.
Almost every commercial roof leak starts at a joint — laps, seams, fixings and sheet ends, not the middle of the sheet. Patching one failure point leaves hundreds of identical ones untouched, and stripping the roof pays for a whole new roof to solve a surface problem.
A seamless GacoFlex membrane seals every joint on the entire roof in one cold-applied system — priced after a free site survey.
Leaks trace to laps, seams or fixings — the classic commercial-roof failure points
Cut edge corrosion on profiled metal sheets — treated as part of the system
Ponding water over a sound substrate — silicone permanently resists it
Metal, felt, single-ply, concrete or asbestos-cement — the membrane bonds directly
The building can’t close — the coating is applied with the doors open
A GacoFlex repair-and-restore approach costs a fraction of strip-and-re-sheet, priced as a fixed written figure after a free site survey.
GacoFlex coatings are engineered for existing commercial roof stock and adhere directly to most surfaces — including weathered or porous substrates — with minimal preparation in many cases.
Duratite is your single point of contact: we survey and specify the repair, then match you with a vetted contractor from our Ireland-wide approved network to carry out the work.
Tell us the building, the roof and where it leaks — a few photos help.
Substrate, ponding, cut edges, access and drainage assessed on site.
System and reinforcement designed, priced fixed — no surprises.
Cold-applied over the live building — no tear-off, doors stay open.
20-year manufacturer-backed product warranty and documentation.
Failing built-up felt over a 35-year-old metal deck, with ponding across 30% of the roof. GacoFlex S42 single-coat silicone was applied with SF42 fibre-reinforced lap-seam treatment and GacoPatch detailing — completed with zero shutdown, and a 20-year manufacturer-backed warranty issued.
Send the building type, the roof and a few photos and we’ll book your free leak survey. For active leaks, GacoPatch gives an instant-cure repair — even in the wet — while we plan the permanent system.
Speak to a roof coatings specialist about your leak — no obligation, no hard sell.
Tell us about your building and we’ll recommend the right system — foam, waterproofing or both — surveyed, specified and quoted at no cost.
