Dollis Hill Roof Leak Investigation
Tracing where water is getting into your roof for Dollis Hill, from an experienced roof surveyor. Every survey comes with a written report and photographs.
- Damp on a chimney breast
- Leaks that appear only in driving rain
- Damp underlay across a wide area
What we do, step by step
Expect us to ask a few questions before we start, such as when any problem began and what work has been done before. Then the inspection itself takes roughly 1–2 hours for most homes, though a hard-to-trace leak can take longer. In Dollis Hill, as in much of London, plenty of properties are flats or terraces without side access, so the back of the roof is frequently seen from upstairs windows, from inside or, where a flight is allowed, from the air. Mention any building rules, key holders or managing agents as you book.
- 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.
- Outside, we check flashings, valleys, chimneys, gutters and flat roof details from each safe vantage point.
- We email a written report showing where the water most likely gets in.
Before we arrive
- Mention any parking restrictions on your street
- Leave a clear route to the loft
- Dig out any old roof reports or invoices
Arrange a survey
A quick phone call is typically the easiest start: phone 07833 053749 or send us an email, and we’ll ask about the building and what you need. The price is agreed before a date is set.
Advice
Roof leak investigations for homes and businesses in Dollis Hill
A leak that comes and goes can be the hardest to pin down. Driving rain from one direction, melting snow or a gutter that overflows in a downpour can all set it off. Notes on when it leaks, and what the weather was doing, help us, along with any photos you’ve taken. Even on a dry day, a leak normally leaves clues: stained timbers, tide marks and damp underlay. Moisture detection shows which materials are still damp. We survey chimney stacks, lead flashings and slate and tile slopes, and people most often book us about drips in the loft during heavy rain and water marks that spread in wet weather.
In converted houses and blocks across London, water from a roof can run a long way before it shows on a ceiling. That makes the source hard to pin down, and finding it matters for whoever has to deal with it. In Dollis Hill, we inspect what we can reach safely and are given access to. It’s useful to know when the water appears and in what weather.
What you get is a clear record of the leaking roof on the day we saw it. That makes it useful now and a handy reference later, such as when you want to compare after future work.

FAQs for Dollis Hill
Do you carry out roof surveys in Dollis Hill?
We do. Every survey there gets the same written report with photographs.
Will parking be an issue for a roof survey in Dollis Hill?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
Do I need to be at home?
Not necessarily. If we only need the outside, we can agree that in advance, but anything inside needs someone there to give access.
What insurance do you have?
Our cover is professional indemnity plus public liability.
What happens next?
We email you the written report with photos and recommendations. It’s yours to share with a seller, insurer, roofer or managing agent, whichever applies.
Can thermal imaging help find my roof leak?
Thermal imaging is used where it’s useful, and it’s included in our Premium Survey. It picks up temperature patterns rather than water, so anything it suggests is checked with moisture readings.
Does this replace a RICS home survey?
No. We are experienced roof surveyors, and our survey covers the roof rather than the whole building. If you need a full building survey, you will need a RICS survey as well.
When to book a survey in Dollis Hill
Blocked gutters can look like a roof leak. Hidden gutters behind parapets cause the most trouble, because when they block, water backs up and runs inside.
A survey can pick up problems such as:
- Brown rings on upstairs ceilings
- Water coming in around a roof light or dormer
- Damp patches next to the stack
- A leak that comes and goes with the weather
For businesses in and around places like Brent Cross Shopping Centre, finding where water is getting in quickly keeps disruption down.
Choosing a roof surveyor
- What the report includes, and whether it has photographs
- Which limits apply to the survey
- Which viewpoints they use to see the roof

Prices for roof leak investigations in Dollis Hill

Getting in touch
What helps most when you contact us:
- Any stains, drips or damp patches you’ve seen indoors
- The address and postcode of the property
- When you need the report by
- Photos of the roof, taken safely from the ground or a window
You can call us seven days a week, including Saturdays and Sundays. To book or ask a question, call 07833 053749 or use the contact form.
Before and after the survey
From years of surveys, a few habits stand out:
- Tell us if there are tanks or pipes in the loft
- Record whether it leaks in every downpour or only some
- Clear the loft hatch so we can get in
- Do not touch fittings that water is reaching
Any roofer you ask to quote can work from the report. The photos show the defects and where they are, rather than at the stain.
After a downpour, look in the loft space with a torch, keeping to boarded areas. Watch for water marks, wet underlay and damp wood. Take photos of anything that changes.
Checking the roof from ground level
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it, which helps when we check the roof.
Inside, the loft is a good place to look, with care. Take a torch and only step on boards or joists, and look for staining, damp timber or daylight coming through.
Why get it checked now?
Wet insulation does not insulate well. A slow leak can soak it for months before a stain appears. The sooner the cause is found, the less needs replacing. A hidden valley or parapet gutter on a London house can hold water for weeks before anyone notices. By the time a ceiling stains, the timbers underneath may have been wet for a while.
Thermal imaging and drone inspection (where it applies) come with the Premium Survey, from £400 inc. VAT. We’ll tell you which package suits the questions you have.
What you get with us
- Independent findings on the roof’s condition
- Over 5,000 surveys carried out
- Thermal imaging and drone inspection where they help

Leaks and storm damage in Dollis Hill
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. The covering and its details give the first clues when tracing where water is coming from. The wider area around Dollis Hill has a long history of building, with Heath House about 2.3 miles east. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and a listed home or one in a conservation area may need consent for changes of material.
Take a building like Our Lady of Grace Catholic Junior School: tracing a leak on a big roof starts with where the water appears and works back. Landlords with a home close to Brent Cross West station may find that finding the cause of a leak fast keeps a tenant’s home dry and the work focused.
