Repairing a Rainwater Outlet at St George's School

The challenge

You're repairing metal, not roofing. An outlet is a metal component set into a roof covering, and the two behave differently. Resin won't bond reliably to bare metal without the surface being prepared and primed first — skip that and the repair lifts within a season, usually somewhere you can't see.

Cracks needed sealing, not bridging. The damage had to be reinforced structurally rather than simply covered. A cosmetic seal over a cracked outlet is a repair that fails the first time it's genuinely tested.

It's a school. Water coming into a building used by children isn't a maintenance ticket to be worked through in due course. It needed assessing and sorting.

What we did

• Assessed the damaged outlet thoroughly before touching it, so the repair addressed what had actually failed rather than what it looked like from a distance.
• Applied a specialist primer to the metal surface — the step that makes everything after it stick, and the one most commonly skipped.
• Applied Lloyd's approved resin to reinforce the structure and seal the cracks, bonding across the damage rather than sitting on top of it.
• Finished with a Lloyd's approved topcoat as a protective layer against weather and UV.

The result

The outlet is repaired and sealed against water intrusion, and the roofing system around it is fortified against future leaks and water damage.

We're proud to support local schools. Buildings like this take a lot of use, budgets are always tight, and the work tends to be unglamorous — outlets, flashings, gutters, the things nobody notices until they fail. Getting those right is what keeps the roof over everyone's head doing its job.
