Need an emergency roofer?

If your flat roof is doing any of these, call now

When you search for an emergency roofer near me, you need someone who picks up and acts, not a quote that lands in your inbox next week. Every downpour pushes more water into the deck, the plaster and the rooms below. If you recognise any of these, the fastest fix is to pick up the phone.

Water coming in right now

The right approach

We stop the leak today, and fix it properly

When you call, the first job is to make your roof watertight and stop the damage spreading. Then we trace the real source, because water travels along the timbers before it drips, so the wet patch is rarely where it’s getting in.

Our van carries everything to make a flat roof watertight on the first visit, patches, sealant, felt and lead. Most emergency repairs are sorted in one go. Where the covering has reached the end of its life, we’ll tell you honestly and give you a written quote before any bigger work starts.

As Icopal-approved contractors, every emergency repair is carried out to the same standard as a full installation. Photo records are taken before, during and after, ideal if you need to make an insurance claim.

  • Roof made watertight on the first visit wherever possible
  • Real source traced, not just the visible wet patch
  • Photo records for your insurance claim
  • Water-tested and guaranteed in writing
