A flat roof with standing water pooling near a drainage outlet

Flat roofs leak fast once the covering fails, because there's no slope to slow the water down, so a small split can mean a wet ceiling within an hour of heavy rain. If that's happening now, call us. We handle emergency repairs separately from our general flat roof work, with the first job being to stop water getting in rather than completing a full repair on the spot.

What does emergency flat roof repair involve?

A temporary, watertight fix to a split, puncture or lifted edge, usually with a bonded patch or temporary sealant suitable for wet conditions, followed by a proper repair once the roof's dry enough to do the job properly. We'll check the whole roof while we're there, not just the obvious leak, since flat roofs often have a second weak point building up that hasn't let water through yet.

What are the signs a flat roof needs emergency repair?

Water visibly coming through a ceiling below the roof, a section of the covering that's torn, lifted or blistered and come away from the deck, or standing water that isn't draining at all are all reasons to call rather than wait for a routine appointment. A flat roof that's just ponding slightly after rain but draining within a day or two is normal and not an emergency on its own, though it's worth a mention when you book routine maintenance.

How long does emergency flat roof repair take?

The temporary fix to stop water getting in is usually done within the same visit, often under an hour for a single, accessible problem. The permanent repair depends on what's needed: a straightforward patch can often be finished the same visit once conditions allow, while anything needing scaffolding, a wider recover, or time for materials to cure properly takes longer and is scheduled separately.

Questions people ask

What should I ask before hiring someone for an emergency flat roof repair?

Ask what the call-out charge covers, whether it includes making the roof watertight or just an inspection, and whether there's a separate cost for the permanent repair. It's also worth asking directly whether they work with your specific roof covering, EPDM, felt or GRP, since a repair done with the wrong material or method doesn't last. If you're not sure what's on your roof, call us for support and advice before you decide who to book.

Do I need to be home for an emergency flat roof repair?

For the first visit, it helps if you're there to point out where the leak's showing and answer questions, but it isn't essential if access to the roof doesn't require going through the house. Let us know in advance if nobody will be home so we can plan access.

How much does emergency flat roof repair cost?

A same-day call-out typically costs in the region of £150 to £300, which covers making the roof safe and watertight. A patch repair to the flat roof covering itself is usually a few hundred pounds on top for straightforward, accessible damage; a repair needing scaffolding or touching a larger area costs more, and we'll confirm that once we've seen it. Keeping outlets and gutters clear afterwards, as part of ordinary maintenance, is the cheapest way to avoid the same problem coming back.
