- Condensation that looks like a leak
How the survey works
Where it is relevant and can be reached safely, the loft space is checked as well as the outside. In the loft, the signs we look for are staining, damp, daylight and sagging. All in, the survey usually takes roughly 1–2 hours for most houses, and more on a big or complicated roof. In Holloway Down, as in much of London, plenty of properties are flats or terraces without side access, so the back of the roof is often 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.
- We help you choose the package that suits the leak.
- We agree a date, including weekends.
- The investigation works from the stain back to the roof.
- Where it’s useful and included, we take moisture readings and use thermal imaging.
- The report explains the likely entry point and what needs attention.
Before the survey
- Jot down any questions you want answered
- If it is not your property yet, arrange access through the agent
- Move anything stored under the loft hatch
Arrange a survey
Buyers should book once an offer has been accepted, so you have the findings in time to act on them before you exchange. For any other survey, just ring 07833 053749 or drop us an email when you are ready.

Roof leak investigations for homes and businesses in Holloway Down
Water is good at hiding where it gets in. Water often travels along timbers or underlay before it finds a way down, so the stain on your ceiling is seldom right under the hole. Our leak investigation traces it back, one likely route at a time. Patching the spot above the stain often misses the real cause. Finding the route first lets the repair go where it is needed. We survey slate and tile slopes, rooflights and dormers and flat roof details, and people most frequently book us about damp underlay across a wide area and damp patches next to the stack.
London’s Victorian and Edwardian roofs have often been repaired many times, 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 typically exclude wear and tear. A careful look in Holloway Down tells the two apart where the evidence allows. A written record with photos helps you explain what was found to whoever deals with it next.
With the Standard Survey, you also get moisture detection, a structural check and a follow-up consultation. The Premium Survey adds thermal imaging, drone inspection where applicable, structural analysis and an in-person consultation.

Tips that help
Small things make a difference, both for the survey and for the roof itself. Our tips:
- Record whether it leaks in every downpour or only some
- Check the loft is accessible
- Keep water away from lights and sockets
- Check whether pipes or tanks run near the stain
Once the work is done, hold on to the report. If the leak returns, it’s a useful record of what was found.
After a downpour, look in the roof space with a torch, keeping to boarded areas. Watch for water marks, wet underlay and damp wood. Take photos of anything that changes.
Roof leak investigations around Holloway Down
Welsh slate on Victorian and Edwardian terraces is a familiar sight across inner London. A butterfly roof with a central valley gutter, tucked behind a parapet wall, is common on these houses. If your home in Holloway Down is one of them, lead flashings, party-wall upstands and shared chimney stacks are part of the picture too. The covering and its details give the first clues when tracing where water is coming from. The wider area around Holloway Down has a long history of building, with Sutton House about 2.4 miles west. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and a listed home or one in a conservation area may need consent for changes of material.
Take a building like The Jenny Hammond Primary School: water through a big roof can travel a long way before it drips, so the search covers more than the obvious spot. For businesses in and around places such as Westfield Stratford City, water through a ceiling can damage stock and close a sales floor, so the source needs finding fast.
Holloway Down is about 1 mile north of Stratford, in Greater London.

Common questions in Holloway Down
Is my home in Holloway Down listed or in a conservation area?
Your council is the best source, with Historic England’s list for listed buildings. Both listing and conservation areas can limit changes of roofing material.
Do you carry out roof surveys in Holloway Down?
We do. Every survey there gets the same written report with photos, and visits run on weekdays and weekends.
What should I do before you arrive?
Note when the leak appears and what the weather was doing. Move stored items away from the loft hatch. If water is near any fittings, have an electrician check them.
Why doesn’t the damp patch line up with the hole?
Water follows the easiest path, not the shortest. On a pitched roof it often runs down a rafter before it shows. Tracing that path is the heart of a leak investigation.
What do I do with the report?
You will get the report by email. With Standard there’s a follow-up consultation; with Premium, an in-person consultation.
Can you always find the source?
Not every leak can be pinned down in a single visit. Many leave clear signs, but some only appear in certain weather. The report sets out what we found and the most likely routes.
Are you structural engineers?
No. We note visible signs such as sagging or deflection, but we do not carry out calculations or give an engineer’s opinion. Where an engineer is needed, we say so in the report.
Why act early in Holloway Down
Wet insulation does not insulate well. A slow leak can soak it for months before a stain appears. Catching it early limits what has to be replaced. Behind a London parapet, a blocked gutter can sit full of water without anyone seeing it. When the stain finally shows, the damage underneath is frequently older than it looks.
Prices start from £150, including VAT, for a Basic Survey. Standard is from £250 and Premium from £400, both inc. VAT. We confirm the exact price before you book.

Different roofs, different checks
Lead flashings
A leak at a flashing frequently shows some way from the joint. That is why we check the flashings near a stain, not just the one directly above.
Chimney stacks
We check the outside of the stack and the breast inside, and it isn’t a flue or gas safety check.
When you need someone else
Before you book, it is worth knowing what a survey won’t do:
- Leaks from plumbing, tanks or pipework rather than the roof
- A promise to find every leak on a single visit
- What’s under the covering or behind the plaster
Not sure which survey suits your roof? You can ring 07833 053749 or email us and we’ll tell you before you book. What a survey covers and doesn’t.

Common roof problems in Holloway Down
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.
Things that often lead to a survey include:
- Water marks that spread in wet weather
- Wet patches on loft insulation
- Leaks at a dormer or roof window
- Damp underlay across a wide area
Landlords with a home close to Maryland station may find that a clear finding on where water gets in helps you brief a roofer straight away.
Choosing a roof surveyor
- How they plan to inspect the roof safely
- What experience they bring
- Whether the loft is part of the inspection
- Is there a chance to talk the report through?
