About our roof leak investigation in Westmill
Some ‘leaks’ are not leaks at all. Condensation in a cold, poorly ventilated loft can drip from nails and timbers, and the stains look much like a leak. Telling the two apart matters, because they need very different work. The pattern of the damp, the ventilation and the timing all help us decide. If you’ve noticed ceiling stains that grow after rain and damp on a chimney breast, we can find out what’s behind it.
Chimney stacks on older houses around places like Westmill can let water in, at the flashings, the pointing or the mortar round the pots. Damp on a chimney breast is not always rain from above, which is why it’s worth tracing properly. The stack, its flashings and the loft space beside it are all worth checking.
Report times depend on the survey you book: Basic within 48 hours, Standard in 24–48 hours and Premium the same day.

Why act early in Westmill
Wet insulation doesn’t insulate well. A slow leak can soak it for months before a stain appears. Catching it early limits what has to be replaced. On a bungalow or cottage around Westmill, the roof sits close to the rooms below, so water can show inside quickly once it gets past the covering. Catching the cause first saves redecorating as well.
Every price we give includes VAT. Prices start from £150, including VAT. You’ll know the price for your roof before booking.

Common questions in Westmill
Is my home in Westmill listed or in a conservation area?
Start with Historic England’s list for listing and your council for conservation areas. Either can affect what roof work is allowed, so it is worth checking before planning any.
Will you come out to Westmill?
Yes, Westmill is covered. We cover the whole of London and South East England, from towns to the smallest villages. The journey is planned ahead, so it is useful to know about access.
Will you go up on the roof?
Only when it is safe. Some roofs are too steep or fragile to walk on safely. Safe viewpoints, the loft and a drone where it applies let us see the rest.
Why is not the leak directly above the stain?
Water rarely drops straight down. It can follow a timber or the underlay a long way first, so the entry point is frequently well away from the mark. That is why we trace the route rather than patching above the stain.
Does someone need to be in?
Someone needs to let us in if we’re looking inside or in the loft. Access is agreed with you when booking.
How long does the visit take?
The visit typically takes about one to two hours for most homes, though a hard-to-trace leak can take longer. We’ll give you an idea of timing when booking.
Are you insured?
Our cover is professional indemnity plus public liability.
Wind, rain and roofs in Westmill
In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile, and flat-roofed additions turn up almost everywhere. Knowing the roof type helps narrow down where water may be getting in. An older home may be listed, or stand in a conservation area. To find out, check Historic England’s list and ask the council about conservation areas. In either case, a change of roofing material may need consent.
Trees in and around Butts Close shed leaves that can end up in nearby gutters, and an overflowing gutter soon means a wet wall. If you own a rental within reach of Hitchin station, finding the cause of a leak fast keeps a tenant’s home dry and the work focused.

What we are asked to look at in Westmill
Flat roofs fail with age and wear. A felt roof frequently lasts around 15 to 20 years, and as it ages it splits, blisters and opens at the laps. Leaks often start at the edges, upstands and outlets.
These are some of the problems a survey can pick up:
- Stains around a skylight
- A leak that comes and goes with the weather
- Water marks that spread in wet weather
- Damp walls below an overflowing gutter
For an older house near a landmark such as St Mark's, the leak may come from a chimney, a valley or tired lead rather than the covering itself.
