Roof leak investigations in Westbourne Green: local notes
Close to the centre of London, a great many houses are Victorian or Edwardian terraces, many of them roofed in Welsh slate. A butterfly roof with a central valley gutter, tucked behind a parapet wall, is common on these houses. In a house like that, shared stacks, party-wall upstands and lead flashings all need looking at as far as they can be seen. The covering and its details give the first clues when tracing where water is coming from. With Kensington Palace about 1 mile south, Westbourne Green sits in an area with a long building history. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and a listed home or one in a conservation area may need consent for changes of material.
Anyone responsible for a site like Edward Wilson Primary School 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. If you live near a park like Emslie Horniman's Pleasance, or anywhere with mature trees, autumn leaves can block gutters and valleys, so outlets and downpipes are worth watching.
Westbourne Green is about 2 miles north-east of Kensington, in Greater London. We carry out roof leak investigations in Westbourne Green for houses, flats, blocks and commercial buildings. We cover towns and villages across Greater London, from the larger towns to small villages.

Roof leak investigation in Westbourne Green
On older houses, leaks often start at lead work and hidden gutters. Worn lead, tired valley linings and blocked parapet outlets are frequent causes. A central valley gutter on a butterfly roof often turns out to be the source in heavy rain. Parapet walls and their gutters are checked from wherever it’s safe. Our report shows what we found, with photos. If you’ve noticed wet patches high on an inside wall and damp patches next to the stack, a survey will tell you what’s going on, on slate and tile slopes, valleys and parapet gutters and lead flashings alike.
Many London homes are well over a century old and their roofs have been patched more than once, so a new leak can be the latest sign of wear rather than a single event. Telling wear from a one-off event matters, because insurers usually exclude wear and tear. A careful look in Westbourne Green tells the two apart where the evidence allows. A written record with photographs helps you explain what was found to whoever deals with it next.
What you get is a clear record of the leaking roof on the day we saw it. It is useful right away, and a good reference for later, like when you want to compare after future work.

Roof by roof
Lead flashings
A leak at a flashing often shows some way from the joint. That’s why we check the flashings near a stain, not just the one directly above.
Flat roof upstands and outlets
Outlets drain a flat roof. When one blocks, water ponds and finds any weak spot. We check outlets and the covering around them.
Why it is worth a survey now in Westbourne Green
Water damage grows the longer it is left. Wet timbers start to decay, plaster softens and insulation stops working. Finding the source early keeps the damage down. Blocked gutters and hoppers on London houses overflow and soak brickwork, which can lead to damp inside. A small blockage left for a few winters becomes a damp problem.
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how it can be reached and seen safely. Roof leak investigation starts from £150, including VAT.

What else we do in Westbourne Green
Signs you need a roof leak investigation in Westbourne Green
Flashings are one of the commonest sources of roof leaks. Lead or mortar closes the gap wherever a roof meets a wall, chimney or dormer. When lead lifts or splits, or a mortar fillet cracks, rain runs straight in, often well away from where it shows.
Common reasons to book include:
- Wet patches high on an inside wall
- Water dripping from rafters or underlay
- Leaks below a flat extension roof
- Staining around the chimney inside
For businesses in and around places like Kensington Arcade, finding where water is getting in quickly keeps disruption down.
Before booking anyone
- When you will get the report
- Will they check the loft as well as the outside?
- Whether VAT is added on top
- How long they’ve been surveying roofs
The survey, step by step
The visit normally starts outside and finishes in the loft: first the slopes, edges and gutters from every safe viewpoint, then the roof space where it can be reached. All told, expect between one and two hours, more where the leak is intermittent or the roof is large. In a London conversion, the way into the roof space is frequently from a communal landing or the top flat. If that applies to your building, it’s useful to agree access with the neighbours or the managing agent first. Otherwise, the visit in Westbourne Green runs like any other.
- 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 is useful and included, we take moisture readings and use thermal imaging.
- You get photos, the likely cause and clear recommendations.
Before we arrive
- Have keys ready for side gates, garages or roof access doors
- Keep pets out of the way during the survey
- Make a note of anything you’d like us to look at

Westbourne Green questions
Is Westbourne Green in the area you cover?
Yes. We work right across London and South East England, and Westbourne Green is part of that. Just phone 07833 053749 or send us an email and let us know about the property.
Will parking be an issue for a roof survey in Westbourne Green?
It can be, so it is useful to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
Does the report include photographs?
Yes, every report has them. Pictures sit next to the findings they show, so you can see what we mean.
Can you find a leak when it isn’t raining?
Often, yes. Stains, tide marks, damp timbers and moisture readings typically point the way. Intermittent leaks can be harder, so your photos and notes from wet days are very useful.
What happens next?
You will get the report by email. With Standard there is a follow-up consultation; with Premium, an in-person consultation, so you can talk the findings through.
Is it the same as a RICS Level 2 or Level 3 survey?
No. We’re experienced roof surveyors, and our survey covers the roof rather than the whole building. If you need a full building survey, you’ll need a RICS survey as well.
When does the report arrive?
That depends on the survey you book: the Basic Survey report arrives within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey the same day. Reports are sent by email.
Checking the roof from ground level
A DIY look is useful, but it isn’t a survey. From the ground, valleys, flashings and the backs of chimneys are often out of sight.
Look up at the roof after a storm, from ground level: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Leave anything above ground level to a survey.
When you need someone else
A survey is a proper look at the leaking roof, but it cannot do everything. The main limits are:
- The repair itself (the investigation finds and reports the cause)
- A structural engineer’s report
- Defects hidden under coverings or inside walls without opening up
If you’re not sure which survey you need, phone 07833 053749 or drop us an email and we will give you a straight answer. The full list of what we check.
