Roof leak investigation in Wealdstone, Greater London
Wondering about the leaking roof at a property in Wealdstone? We carry out roof leak investigations in Wealdstone and across Greater London.
- Leaks that appear only in driving rain
- Water coming in around a roof light or dormer
- Water through the ceiling under a flat roof
How it works
The visit usually starts outside and finishes in the loft: outside views come first, then the loft space if there’s safe access. All told, expect an hour or two for most homes, though a hard-to-trace leak can take longer. In Wealdstone, as in much of London, plenty of properties are flats or terraces without side access, so rear slopes are viewed from windows, the loft or, where a flight is allowed, by drone. If the building has a managing agent or access rules, let us know when booking.
- 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.
- Moisture detection and thermal imaging are used where your package includes them and they help.
- You get photos, the likely cause and clear recommendations.
Preparing for the visit
- Leave side gates unlocked
- Move anything stored under the loft hatch
- Have any paperwork from past roof work to hand

Prices start from £150, including VAT. The exact figure depends on the roof and the package, and you can call 07833 053749 or drop us an email to find out.
Advice
About our roof leak investigation in Wealdstone
We investigate roof leaks in Wealdstone and across London and the South East. We visit seven days a week. We look inside and out, at flashings, valleys, chimneys, gutters and flat roof details. The findings come in a written report with photos. If it is leaking right now, contain the water and keep it clear of electrics, and then call 07833 053749 or send us an email to arrange a visit. Common reasons to book are staining where a gutter or parapet meets the wall and leaks that appear only in driving rain, across slate and tile slopes, the roof space and rooflights and dormers.
Water getting into a London home frequently comes from a detail you can’t see from the street: the valley gutter in a butterfly roof, a parapet gutter, a chimney flashing or the flat roof over a rear extension. For a leak or storm damage in Wealdstone, those hidden details are where the inspection begins. A hidden gutter that overflows can send water a long way before it shows.
Report times depend on the survey you book: Basic within 48 hours, Standard in 24–48 hours and Premium the same day.

Landlord and commercial surveys in Wealdstone
Shared roofs need a little more planning: we need access agreed with whoever owns or manages the building. Mention it when you contact us and we will plan the survey around it.
With a portfolio of properties, you can book surveys for several addresses. To arrange surveys for several addresses, call 07833 053749 or send us an email with the addresses.
What a survey costs
All our prices include VAT. What changes the price is:
- How big the roof is
- The shape of the roof and its details
- How many separate roofs there are, like extensions, dormers and garages
- Any need for thermal images or a drone flight
Thermal imaging and drone inspection (where it applies) come with the Premium Survey, from £400 including VAT. We can help you choose the package that fits what you’d like to know.
Getting in touch
To price your survey accurately, we will ask about:
- How the loft is reached, if there is one
- Where any leaks, stains or damp patches show inside
- Where the property is, with the postcode
- Any deadline, such as an exchange date
Unsure which package suits your roof? It is easiest to ring 07833 053749 or email us and describe the roof and what’s worrying you. We’ll talk you through the options and what they cost.
Before and after the survey
Some practical points come up on survey after survey. They apply to most roofs:
- Tell us if there are tanks or pipes in the loft
- Let us know about any past repairs to the roof
- Don’t touch fittings that water is reaching
- Clear the loft hatch so we can get in
Keep the report after the work is done. If water appears again, it shows what was found before.
Keep gutters, valleys and outlets clear, especially in autumn. Many leaks start with a blocked outlet. Use a professional rather than climbing up yourself.
FAQs for Wealdstone
Can parking be tricky for a visit in Wealdstone?
It can be, so it’s useful to tell us about permits, visitor bays or off-street space as you book. The visit is then planned around what’s available.
Is Wealdstone in the area you cover?
We do. Every survey there gets the same written report with photos.
How experienced are you?
We have more than 20 years’ experience and have completed over 5,000 surveys.
Does the report include photos?
Yes. We photograph the roof as we go, and the report uses them to show each finding alongside our recommendations.
I live in a flat. Can you survey the roof?
Yes. Shared roofs just need a little more planning. Mention it when you get in touch and we will plan the survey around it.
What’s the best way to book?
The quickest way is to call 07833 053749 or drop us an email. Give us the address and some details about the roof, and we will suggest the right survey. We survey on weekdays and at weekends.
Will you fix the leak as part of this?
The investigation is about finding the cause. The repair itself is a separate job. You get a report with photos showing where the water is getting in and what needs attention, which whoever carries out the work can follow.
What you can safely check yourself
What you can’t do safely is get up close. Roofs are fragile and slippery, and falls from height are serious. That is where a survey comes in.
You can learn a lot from the ground. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Please do not climb up for a closer look.

Roof leak investigations around Wealdstone
Historic houses such as Headstone Manor, about 0.9 miles west, show how far back building in the area around Wealdstone goes. Older roofs in the wider area can hide decades of patch repairs, so the detail matters. 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. Each of these roof types has its own typical places for water to get in.
The streets around a church such as Holy Trinity Church are frequently among the oldest in a place, and if your home is one of the older ones nearby, lead flashings, valleys and old chimneys are typical places for water to get in. For landlords with property near Harrow & Wealdstone station, a tenant living with a leak needs the cause found, not just the stain painted over. For site and facilities teams at buildings such as Marlborough Primary School, tracing a leak on a big roof starts with where the water appears and works back.

What we look for on each type of roof
Slate and tile slopes
On slate roofs, corroded nails let slates slip. One slipped slate can be enough to cause a leak.
Valleys
Valleys collect water from two roof slopes. Worn or split linings and slipped valley tiles let it under the coverings.
