Services/Repairs and leaks/

The stain is not where the hole is.

Water gets in at a flashing or a slipped slate, runs down the back of a rafter and drops off somewhere else entirely. Chasing the damp patch is how people end up paying to fix three things that were never wrong.

No call-out charge, and the phone is answered 24 hours.

Leaking roof repair.

A leak has two ends and they are rarely in the same place. Water finds its way under the covering, then travels — along the top of a rafter, down the side of a purlin, along a nail, sometimes several metres across a loft — before it finds a gap in the plasterboard and announces itself. So looking only at the ceiling below the stain tells you where the water gave up, not where it got in.

That is why we go into the loft first on any leak that is not obvious from the ground. In daylight, with the lights off, a hole in the covering usually shows itself. Tide marks and dark staining on the timbers show the run. Wet insulation in one spot and dry either side tells you where it is landing. Ten minutes up there saves an afternoon of guessing on the roof.

It is also worth ruling out the things that are not the roof. Condensation in a poorly ventilated loft soaks insulation and drips without a drop of rain involved. A leaking waste pipe or a failed shower tray in a bathroom below a flat roof does a convincing impression of a roof leak. We would rather tell you it is a plumber's job than sell you a repair that changes nothing.

How we find it

  • The loft checked first, in daylight with the lights off
  • Timbers read for tide marks and the run of the water
  • Insulation checked for where it is actually landing
  • Flashings, valleys, abutments and chimney fillets inspected
  • Slates lifted where a suspect fixing needs checking
  • A hose test where the source is genuinely not obvious
  • Condensation and plumbing ruled in or out honestly
  • Photographs of the cause, with the repair priced in writing

Worth knowing.

Leak or condensation?
A leak follows the weather. Condensation turns up on cold still mornings and soaks the insulation evenly. Different problem, different fix, and one of them is in the loft.
Chimneys first
If there is a stack anywhere near the stain, that is where we look first. Cracked cement fillets and tired flashings are the most common single cause we find.
It stopped by itself
Leaks that come and go are usually wind-driven — it only gets in when the rain arrives from one particular direction. That is a real fault, not a fluke.
Insurance
Gradual wear is not usually covered, storm damage usually is. We photograph what we find either way so you have something to send them.

The other things we do.

Most jobs turn out to be more than one of these at once. If you're not sure which you need, describe what you can see and we'll work it out.
