- Roof area

Prices quoted always include VAT, and the written report is part of the package. Roof leak investigation starts from £150, including VAT. Size, height and access decide where your roof falls.
Booking your survey
A little information up front helps. Please include:
- Anything about access we should know
- Where water is showing inside, if it is
- Pictures from the garden or a window, if you have them
- Where the property is, with the postcode
Buyers should book once an offer has been accepted, so you have the findings in time to act on them before you exchange. Otherwise, simply phone 07833 053749 or drop us an email whenever suits you.
About our roof leak investigation in Hanwell
On older houses, leaks often start at lead work and hidden gutters. Lead flashings crack or lift, valley linings wear and parapet gutters overflow when outlets block. A central valley gutter on a butterfly roof frequently turns out to be the source in heavy rain. We check parapets, valleys and flashings from each safe vantage point. Our report shows what we found, with photos. We survey flat roof details, chimney stacks and slate and tile slopes, and the problems we’re asked to look at most are ceiling stains that grow after rain and wet patches on loft insulation.
In a London flat, water can travel some way before it shows. That makes the source hard to pin down, and finding it matters for whoever has to deal with it. We look at what we’re given access to in Hanwell, inside and out. Tell us when the water shows, and in what kind of weather.
Most points in the report come with a picture, so you can see each defect rather than just read about it. If something couldn’t be seen safely, the report is clear about it.

Hanwell roofs and the weather
Historic houses such as Pitzhanger Manor, about 1.3 miles east, show how far back building in the area around Hanwell goes. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead. 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. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Each of these roof types has its own typical places for water to get in.
Shop and office owners around Treaty Centre may find that finding where water is getting in quickly keeps disruption down. If you own a rental within reach of Hanwell station, tracing a leak quickly matters when a tenant is living with it.
Hanwell is about 1 mile west of Ealing, in Greater London. We survey roofs in Hanwell and the surrounding area across London and South East England. We cover towns and villages across Greater London. London is in our area too.

Near you in Hanwell
Locally, jobs take us to homes and businesses close to Drayton Manor High School, Cuckoo Schools and Drayton Green, among other places. There is a railway station in Hanwell itself: Hanwell station. Well-known places in the area include Ealing Hospital (within half a mile west) and Gunnersbury Park House - Large Mansion (2.3 miles east). For a walk, there’s Middle Lake and Castlebar Hill.
Can I check my roof myself?
After heavy rain, check ceilings and the tops of walls for new stains. Photograph them and note the date, which helps when we check the roof.
The one thing to avoid is getting up close. Roofs are fragile and slippery, and falls from height are serious. That’s where a survey comes in.

What happens on the day
We do not take risks to get a closer look. Everything that can be seen safely is inspected, and if part of the roof cannot be seen, the report says so. Most visits take between one and two hours for most homes, though a hard-to-trace leak can take longer. In a London area like Hanwell, the main things to sort out are parking and access: let us know about parking, the floor the property is on, any shared entrance and loft access. On the day, the roof is looked at from ground level, from windows, from inside the loft space and from the roof where it’s safe.
- You let us know where the water appears, when, and what the weather was doing.
- Inside, we check the stain and the ceiling around it.
- In the loft, we follow any signs of water back towards the roof.
- We inspect the likely entry points outside, from the ground, windows and the roof where safe.
- You receive a report with the likely source, photos and recommendations.
Getting ready for the survey
- Point out any leaks or damp patches
- Mention any parking restrictions on your street
- Leave side gates unlocked

Signs you need a roof leak investigation in Hanwell
Blocked gutters can look like a roof leak. Parapet and box gutters are the worst for this, since a blocked outlet sends water over the lining and into the building.
Signs worth acting on include:
- A leak that comes and goes with the weather
- Water through the ceiling under a flat roof
- Wet patches high on an inside wall
- Drips from nail tips in a cold loft
Homes near green spaces like Drayton Green can get more leaves in their gutters in autumn.
Questions to ask before you book
- Whether you can ask questions once you have the report
- Their report turnaround times
- What experience they bring
- Whether VAT is added on top
Before and after the survey
Small things make a difference, both for the survey and for the roof itself. Our tips:
- Photograph the stain each time it appears
- Record whether it leaks in every downpour or only some
- Do not climb onto the roof to look
- Catch drips in a bucket and protect the floor
Your report arrives by email, with photos of what we found. It explains the likely entry point, the route the water takes and our recommendations. Turnaround is within 48 hours for Basic, 24 to 48 hours for Standard and the same day for Premium.
Check the loft after heavy rain, with care and a good torch. Watch for water marks, wet underlay and damp wood. Photograph anything new.
Landlords, agents and block managers in Hanwell
Shared roofs need a little more planning: access has to be agreed with whoever owns or manages the building. Mention it when you get in touch and we will plan the visit with that in mind.
If you own several properties, you can book surveys for several addresses. To arrange surveys for several addresses, phone 07833 053749 or email us with the addresses.
Hanwell: your questions answered
Do you cover Hanwell?
We do. Every survey there gets the same written report with photos, and visits run on weekdays and weekends.
Will parking be an issue for a roof survey in Hanwell?
It rarely stops a survey, but it is worth planning. Let us know the parking rules on your street and we’ll work around them.
Is there anything I need to do ahead of the visit?
Keep a note of when it leaks, and take photos. Move stored items away from the loft hatch. If water is near any fittings, have an electrician check them.
Is it a structural engineer’s report?
No. Our survey is not a structural engineer’s report, and it does not include calculations. If we see signs that need an engineer’s opinion, we will recommend one.
How much is a survey?
Prices start from £150, including VAT. Our three packages are Basic from £150, Standard from £250 and Premium from £400, including VAT.
Is it the same as a RICS Level 2 or Level 3 survey?
No. It’s a specialist roof survey, not a RICS Level 2 or Level 3 building survey. It focuses on the roof, so it sits alongside a building survey rather than replacing it.
How long have you been surveying roofs?
We’ve completed more than 5,000 surveys, across 20+ years of surveying roofs, and 98% of clients are satisfied.
