Signs you need flat roof junction and flashing repairs

  • Leak near the lantern but not from the frame
  • Splits, blisters or lifted edges in the roof covering by the kerb

Unbonded membrane

EPDM or single-ply that has come away from the kerb lets water run behind it.

Missing trims

Without a trim or flashing to protect the top edge, water gets in behind the membrane.

Can you repair a lantern someone else installed in Wrexham?

Yes. We repair lanterns whoever fitted them. If yours is still under the installer's warranty, contact them first so you don't affect it.

Do you repair the whole flat roof?

We repair the area around the lantern. If the wider roof is failing we'll tell you and can quote, but we won't push a new roof if a local repair will do.

Can you repair a GRP roof without it showing?

Repairs are colour-matched as closely as possible, but new topcoat next to weathered topcoat can look slightly different at first.
