About our roof leak investigation in West Drayton
A leak that comes and goes can be the hardest to pin down. Wind-driven rain, an overflowing gutter or snow melt may be what triggers it. Notes on when it leaks, and what the weather was doing, help us and so do photos. We look for the clues it leaves behind, such as tide marks, stained timbers and damp underlay. Moisture readings show where materials are still wet. We survey the roof space, lead flashings and valleys and parapet gutters, and the problems we are asked to look at most are water marks that spread in wet weather and leaks at a dormer or roof window.
In a London flat, water can travel some way before it shows. Tracing it back matters, both for dealing with the cause and for any insurance claim. We look at what we’re given access to in West Drayton, inside and out. It helps to know when the water appears and in what weather.
You receive the findings by email, easy to pass on to a roofer, an agent or an insurer. Turnaround is within 48 hours for Basic, 24–48 hours for Standard and same day for Premium.

Should I look at the roof myself first?
Your own check is a good start, but it isn’t a survey. From the ground, valleys, flashings and the backs of chimneys are often out of sight, and those are details a survey looks at closely.
It helps to keep a record: dates of leaks, photos from ground level and any work done on the roof. Send it with your enquiry, as it helps us focus the survey.
Before and after the survey
From years of surveys, a few habits stand out:
- Take dated photos of the leak
- Move stored items away from the hatch
- Have an electrician check any wet fittings
- Record whether it leaks in every downpour or only some
Standard includes a follow-up consultation to talk the findings through, while Premium includes one in person. It is a chance to ask about anything in the report.
Keep the roof space ventilated. Air movement keeps condensation down, which is often mistaken for a leak. Check insulation doesn’t block airflow at the eaves.
Signs you need a roof leak investigation in West Drayton
Flashings are one of the commonest sources of roof leaks. Where a roof meets a chimney, a wall or a dormer, lead or mortar seals the joint. When lead lifts or splits, or a mortar fillet cracks, rain runs straight in.
Here are some of the things we see often:
- Water dripping from rafters or underlay
- A leak that comes and goes with the weather
- Damp patches next to the stack
- Water through the ceiling under a flat roof
Anyone responsible for a site like West Drayton Academy will know that water through a big roof can travel a long way before it drips, so the search covers more than the obvious spot.

Leaks and storm damage in West Drayton
Further from the centre, London’s housing takes in interwar semis with hipped roofs in clay or concrete tiles as well as slate-roofed terraces. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Knowing the roof type helps narrow down where water may be getting in. Ickenham Hall, about 4.2 miles north, is one of the historic houses in the wider area around West Drayton. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and a listed home or one in a conservation area may need consent for changes of material.
If you let a flat or house near West Drayton station, finding the cause of a leak fast keeps a tenant’s home dry and the work focused. Take an older house close to Church of St Martin: old mortar, worn lead and slipped slates are the usual suspects when water gets in.
West Drayton is about 2 miles west of Hayes, in Greater London. If you are in West Drayton, booking works exactly as it does anywhere else: a call or an email, a price, then a date. Our Greater London coverage includes West Drayton. London is in our area too.

When you need someone else
This isn’t a RICS building survey, a structural engineer’s report or an asbestos survey. It also has these limits:
- What’s under the covering or behind the plaster
- Leaks from plumbing, tanks or pipework rather than the roof
- An intermittent leak that shows no trace on the day

What else we do in West Drayton
What we do, step by step
We look at the roof from outside and, where it’s relevant and there is safe access, from inside the loft space too. Inside, we look for staining, damp, gaps and signs of movement. All in, the survey normally takes roughly 1–2 hours for a house, though large, tall or awkward roofs take more time. In West Drayton, visits are available on weekdays and at weekends. London parking is often by permit or pay-and-display, so it’s useful to know what’s near you. A back bedroom window can be the best vantage point for a rear addition, so we may ask to use one.
- We start with your notes and photos of the leak.
- We examine the damp area and the rooms near it.
- In the loft, we follow any signs of water back towards the roof.
- Outside, we check flashings, valleys, chimneys, gutters and flat roof details from every safe vantage point.
- You receive a report with the likely source, photos and recommendations.
Getting ready for the survey
- Check the loft hatch can be reached
- If you are buying, let the agent know when we’re coming
- Leave side gates unlocked
Booking a survey
A quick phone call is normally the easiest start: call 07833 053749 or use the contact form. You will have a price before anything is arranged.

West Drayton: your questions answered
Is parking a problem for a survey in West Drayton?
It rarely stops a survey, but it’s worth planning. Tell us what parking is available nearby, and the visit is planned around it.
Do you cover West Drayton?
We do. Every survey there gets the same written report with photographs, and visits run on weekdays and weekends.
Does the report include photographs?
Yes. We photograph the roof as we go, and the report uses them to show each finding alongside our recommendations.
How should I prepare for the leak investigation?
Note when the leak appears and what the weather was doing. Clear access to the loft. Keep away from any light or socket that water is reaching.
What happens after the survey?
You’ll get the report by email. With Standard there’s a follow-up consultation; with Premium, an in-person consultation, so you can talk the findings through.
How many surveys have you done?
Over 5,000 surveys so far, across 20+ years of surveying roofs, with 98% customer satisfaction.
Do you need to get into the loft?
Where it is relevant to the survey and there is safe access, yes. A clear path to the hatch helps, and if the loft cannot be reached safely, the report says so.
