Roof Leak Detection in Lincolnshire, Cambs & Norfolk

Where the water drips is rarely where it gets in. We trace roof leaks back to their source before anything is replaced, show you photos of what we find, and fix the cause rather than the symptom.

The problem

Why leaks keep coming back

Water travels. It can get in at a cracked flashing, run down a rafter or along the felt, and drip through a ceiling several feet away. Fix the spot above the stain and the leak simply carries on.

That's why so many of our customers come to us after one, two or three repairs that didn't work. Often there's more than one entry point, or the real culprit is hidden — torn felt under sound-looking tiles, a perished flashing, or a blocked valley.

Signs to look out for

  1. 01A stain that reappears after every heavy rain
  2. 02Leaks only in wind-driven rain from one direction
  3. 03Drips near a chimney, skylight or vent pipe
  4. 04Water marks on rafters or the underside of the felt
  5. 05Damp insulation with no obvious hole above
  6. 06A leak that a previous repair didn't stop

How we fix it

Trace it, photograph it, fix it

We start inside, in the loft where we can, following water marks on timbers and felt back towards where they start. Then we go up and check every likely entry point in that area: tiles, ridges, valleys, flashings, vent pipes, chimneys and skylights.

When we find it, we photograph it and show you. If we need to lift tiles to see what's underneath, we do, so we're not guessing — and you'll see exactly what we saw.

The repair is then targeted at the actual cause, whether that's lapping in new membrane, renewing a lead flashing, clearing and relining a valley or replacing damaged tiles. You only pay for the fix that's needed.

What we check

Felt & membrane
Torn or perished underlay is one of the most common hidden causes of leaks.
Flashings & valleys
Lead and mortar around chimneys, walls and valleys, where water concentrates.
Penetrations
Vent pipes, skylights, aerial brackets and solar fixings — anywhere the roof is pierced.
Tiles, ridges & verges
Cracks, slips and failed mortar letting wind-driven rain underneath.

Good to know

What you can check before we arrive

If it's safe, have a look in the loft with a torch during or just after rain. Note where you see drips, wet timber or damp insulation, and take a photo. It doesn't need to be perfect — it gives us a head start on where to look.

Make a note of when the leak happens. Is it every time it rains, only in heavy downpours, or only when the wind is blowing from one direction? Does it appear straight away or hours later? Those details help narrow down the cause.

Finally, if someone has worked on the roof before, tell us what they did. It's often the area around a previous repair that turns out to be the problem.

Don't worry if you can't get into the loft or don't want to go up there. We can do all of this ourselves — it just helps to know anything you've already noticed. And if water is coming in right now, call us rather than waiting; we offer 24/7 emergency call-outs to make the roof watertight first and trace the cause properly afterwards.

FAQs

Leak detection: your questions

Why does my roof only leak in certain weather?

Leaks that appear only in wind-driven rain usually point to a gap that's normally sheltered — a lifted tile, a gap at the verge or a flashing that's pulled away. We'll check the side of the roof facing the weather.

Do you need access to my loft?

It helps a lot. Water marks on rafters and felt are often the best clue to where a leak starts.

Will you lift tiles to look underneath?

Yes, where it's needed to find the cause. We put them back properly afterwards.

Someone has already tried to fix it — can you help?

Yes. A lot of our leak work is on roofs where earlier repairs didn't solve it. We'll look at what was done and find what was missed.

How quickly can you come out?

Often the same day or the next day. If water is coming in now, call us — we offer 24/7 emergency call-outs.

Can a leak come from somewhere other than the roof?

Sometimes. Condensation in a poorly ventilated loft, a leaking water tank or pipe, or water running in from a blocked gutter can all look like a roof leak. We'll check for these too and tell you honestly if the roof isn't the culprit.
