Roof leak investigations for homes and businesses in Hillingdon
Flat roofs leak in their own ways. Common causes are splits and blisters, tired upstands and outlets that do not drain. Standing water puts extra pressure on every weak point. We look at the roof surface and the ceiling below to narrow it down. Flat roofs over extensions, garages and dormers are frequent sources of leaks. An ageing felt roof is a frequent culprit. If you’ve noticed damp underlay across a wide area and leaks below a flat extension roof, we can find out what’s behind it.
Water getting into a London home frequently comes from a detail you cannot see from the street: 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 Hillingdon, those hidden details are where the inspection begins. Water from a hidden gutter can run along joists and show up a room or two away.
You can share the report with anyone who needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent, whichever applies.

Why get it checked now?
Damp loft insulation loses much of its value. Insulation can soak up water quietly before anything shows below. Catching it early limits what has to be replaced. Blocked gutters and hoppers on London houses overflow and soak brickwork. A small blockage left for a few winters becomes a damp problem.
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. You will know the figure before booking.

We only report whatever is safely visible on the day, so some things are outside what a survey can do:
- A structural engineer’s report
- Leaks from plumbing, tanks or pipework rather than the roof

What to let us know when you get in touch
The more you let us know, the easier it is to price the survey. When you get in touch, it helps to mention:
- The kind of building and roof involved
- Dates you’re working to, like exchange
- What made you get in touch
- Pictures of the roof from a safe spot, if you have them
Photos help, if you have them. Take them safely from the ground or a window; never climb up to get a better view. To send them or to book, call 07833 053749 or send us an email.
Different roofs, different checks
Flat roof upstands and outlets
On a flat roof, a leak can show some distance from the split. Moisture readings and thermal imaging can help narrow it down where conditions suit.
Slate and tile slopes
On slate roofs, corroded nails let slates slip. One slipped slate can be enough to cause a leak.
Hillingdon questions
Can parking be tricky for a visit in Hillingdon?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
Do you carry out roof surveys in Hillingdon?
We do. Every survey there gets the same written report with photographs.
What do I do with the report?
The report arrives by email, with photos and clear recommendations. The Standard Survey includes a follow-up consultation, and the Premium Survey an in-person consultation.
Will you go up on the roof?
Only where it’s safe to do so. We check everything that can be seen safely: from ground level, from windows, from inside the roof space, from the roof where it is safe and by drone where it applies. The report says if anything couldn’t be seen.
Are you insured?
We’re covered by professional indemnity and public liability insurance, for every survey we carry out.
Could my leak actually be condensation?
It’s a common question. Leaks tend to follow wet weather and show in one place, while condensation is often widespread and worst on cold days. We tell you which it is most likely to be.
Will you fix the leak as part of this?
Our job here is to trace the leak and explain it, and the repair is separate. The report gives any roofer a clear brief.
Should I look at the roof myself first?
Fresh stains on ceilings or walls after rain are worth noting. Take a photo and write down when you saw it, which helps when we check the roof.
You can learn a lot from the ground. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Never climb onto the roof to look.
What we do, step by step
Every visit follows the same pattern: we hear what you’ve seen, inspect the roof from every safe vantage point, take photographs as we go and record our findings for the written report. It usually takes about 1–2 hours on an ordinary house, and about three to four hours for a commercial roof. London terraces rarely offer a view of the whole roof from one spot, so in Hillingdon we work round the house, using the street, the windows, the loft and any safe vantage point behind it. If other people live in the building, tell us who can let us into the shared parts.
- We start with what you’ve seen: where the stain is and when it gets worse.
- We check the stain, the ceiling and the loft above it.
- Likely entry points outside are checked, from flashings and valleys to gutters and outlets.
- We use moisture detection, and thermal imaging where it is useful.
- We email a report with photographs, the likely entry point and recommendations.
Before we arrive
- Make sure the loft hatch can be reached
- If it isn’t your property yet, arrange access through the agent
- For flats, check roof access has been agreed

Roof leak investigations around Hillingdon
Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of clay or concrete tiles. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Different coverings let water in at different points, which shapes where the search starts. Historic houses such as Ickenham Hall, about 1.8 miles north, show how far back building in the area around Hillingdon goes. If yours is one of the older homes, expect a mix of original materials and later repairs on the roof, and a listed home or one in a conservation area may need consent for changes of material.
For businesses in and around places such as The Chimes, water through a ceiling can damage stock and close a sales floor, so the source needs finding fast. Living close to Norman Leddy Memorial Gardens is pleasant, but mature trees mean leaves in gutters and valleys each autumn, and blocked gutters overflow and soak walls. Take a building like Abbotsfield School for Boys: a leak through a large roof is often found some distance from where the water shows inside.
