Recognise Any Of These? We Can Fix Them.

Large flat roofs on garages, extensions and outbuildings are particularly vulnerable. A failing membrane lets water track into the structure before you notice it inside. By the time damp appears on the ceiling, the deck below may already be compromised.

Persistent leak

If water is tracking into rooms or staining ceilings after rain. We help by diagnosing the actual source of the leak, not just patching where it is wet, and carrying out a lasting repair.

Damp Patches on Ceiling

If damp patches are appearing on ceilings below the flat roof without visible rain. We help by tracing moisture ingress that has been tracking through the roof structure before showing itself inside.

Blistering or Cracking

If the existing covering is lifting, bubbling or splitting across the surface. We help by assessing whether a repair or full replacement is the right solution and carrying out the correct fix.

Standing Water On Roof

If water is sitting on the roof and not draining away after rain. We help by identifying the cause and correcting it properly, whether that is failed falls, a blocked outlet or a sunken area.

Failed repairs

If patches keep coming back and the same areas are leaking repeatedly. We help by identifying whether the problem can be repaired properly or whether the covering has reached end-of-life.

Storm or Impact Damage

If the roof has been damaged by a fallen branch, debris or severe weather. We help by assessing the full extent of the damage and providing documentation for any insurance claim.

Flat Roof Repairs: Finding The Source, Fixing It Properly

Most flat roof leaks are misdiagnosed. Water travels along roof timbers and battens before it drips, which means the visible wet patch on your ceiling is rarely directly below the point of entry. We trace the actual source before we touch anything.

Once we have identified the source, we give you a written quote before any work starts. We carry out a lasting repair using materials appropriate to your roof type, whether that is GRP fibreglass, EPDM rubber or torch-on felt. We also check the full roof envelope while we are there, so secondary issues are flagged before they become leaks.

As Icopal-approved contractors, every repair is carried out to the same standard as a full installation. Photo records are taken before, during and after every job, and every repair comes with a written guarantee.
