- Carrying out the fix
- Faults hidden behind ceilings or boarding
- Leaks from plumbing, tanks or pipework rather than the roof

About our roof leak investigation in Pimlico
Some ‘leaks’ are not leaks at all. In a badly ventilated roof space, condensation can form under the roof and drip, and the stains look much like a leak. Knowing which it is means the right fix can be done, because they need very different work. We look at the pattern of damp, the weather and the ventilation before reaching a view. Common reasons to book are water marks that spread in wet weather and condensation that looks like a leak, on valleys and parapet gutters, slate and tile slopes and flat roof details.
In London, leaks frequently start somewhere hidden: a butterfly roof’s central valley gutter, a parapet gutter, a chimney flashing or a flat roof over a back addition. For a leak or storm damage in Pimlico, those hidden details are where the inspection begins. A hidden gutter that overflows can send water a long way before it shows.
If any part of the leaking roof couldn’t be seen safely, we say so in the report. You’ll know exactly what was inspected and what wasn’t, and what we’d suggest next.

Common roof problems in Pimlico
A roof valley collects the rain from two slopes. Split linings, slipped valley tiles or debris can send that water under the coverings. Leaks from valleys often show up some distance away inside.
We are frequently asked to look at:
- Ceiling stains that grow after rain
- Damp walls below an overflowing gutter
- Damp on a chimney breast
- Water through the ceiling under a flat roof
For businesses in and around places such as Harrods, water through a ceiling can damage stock and close a sales floor, so the source needs finding fast.
Before you book any roof surveyor
- Which limits apply to the survey
- Whether you can ask questions once you have the report
- Whether the loft space is looked at, where there is one
- What insurance they carry
How the survey works
Photos are taken throughout the visit, so the report shows exactly what we saw. We take close-ups from wherever is safe. Most surveys take roughly 1–2 hours on an ordinary house, though large, tall or awkward roofs take more time. London terraces rarely offer a view of the whole roof from one spot, so a visit in Pimlico moves between viewpoints: the pavement, upstairs windows, the loft and any safe spot at the back. Shared stairs or a basement flat? Let us know who holds the keys.
- We help you choose the package that suits the leak.
- A visit is booked for a weekday, Saturday or Sunday.
- We inspect inside and out, starting from the stain.
- Where it’s useful and included, we take moisture readings and use thermal imaging.
- The report explains the likely entry point and what needs attention.
How to prepare
- Dig out any old roof reports or invoices
- Let us know about parking before the day
- Keep pets in another room

Advice
Questions from Pimlico
Can parking be tricky for a visit in Pimlico?
Sometimes, yes. If Pimlico has controlled parking where you are, a visitor permit is the easiest answer.
Is Pimlico in the area you cover?
Yes, Pimlico is one of the places we work. Every survey there gets the same written report with photos.
How experienced are you?
We’ve completed more than 5,000 surveys, over more than 20 years.
Can every leak be traced?
Not every leak can be pinned down in a single visit. Many leave clear signs, but intermittent leaks that need particular weather can be harder. We report what we found and the likeliest sources.
Can you give me structural calculations?
No. Visible signs such as deflection or sagging are recorded, but we don’t provide calculations or an engineer’s opinion. The report will say if you need an engineer.
Does someone need to be in?
Not necessarily. If we only need the outside, we can agree that beforehand, but the loft and any rooms with damp need someone to let us in.
Is thermal imaging part of a leak investigation?
We use thermal imaging where it helps, and it’s part of the Premium Survey. It picks up temperature patterns rather than water, so we confirm its findings with moisture readings.
Why get it checked now?
Damp in a ceiling or loft can lead to mould. It’s unpleasant, and it is harder to deal with once established. Stopping the water is the first step. In a London terrace or conversion, a roof defect rarely stays your problem alone: failed flashings and blocked valley gutters can send water into more than one home. Dealing with it early is far less disruptive.
The Premium Survey includes thermal imaging and drone inspection where it applies, from £400 with VAT included. We will tell you which package suits the questions you have.

Useful tips for Pimlico property owners
There is plenty you can do without going near the roof. What helps most:
- Check whether pipes or tanks run near the stain
- Take dated photos of the leak
- Write down the wind direction and rain when it leaks
- Catch drips in a bucket and protect the floor
Keep the report after the work is done. If water appears again, it shows what was found before.
Keep the loft space ventilated. Good airflow reduces condensation, which is often mistaken for a leak. Make sure insulation does not block airflow at the eaves.
Leaks and storm damage in Pimlico
Close to the centre of London, a great many houses are Victorian or Edwardian terraces, many of them roofed in Welsh slate. Many have butterfly roofs draining to a central valley gutter, with parapet walls and gutters hidden behind them. If your home in Pimlico is one of them, lead flashings, party-wall upstands and shared chimney stacks are part of the picture too. Different coverings let water in at different points, which shapes where the search starts. The wider area around Pimlico has a long history of building, with Buckingham Palace about 0.9 miles north. If yours is one of the older homes, expect a mix of original materials and later repairs on the roof, and the council can say whether a home is in a conservation area.
Homes near green spaces such as Pimlico Gardens can get more leaves in their gutters in autumn. If you let a flat or house near London Victoria station, a tenant living with a leak needs the cause found, not just the stain painted over.

Roof by roof
Valleys
Valleys collect water from two roof slopes. Split lead, cracked linings or slipped tiles let water in.
Chimney stacks
Damp on a chimney breast inside often starts at the top of the stack. Unused flues with open pots can let rain straight in.
