Roof leak investigations for homes and businesses in Bow
Leaks tend to begin where one part of a roof meets another. Flashings at chimneys and walls, valleys, gutters, parapets and flat roof upstands and outlets are the usual suspects. Each of these is checked in turn and follow the evidence. Every chimney, dormer and roof light adds more joints to check. We check all of them, from every safe vantage point. We survey chimney stacks, flat roof details and valleys and parapet gutters, and common reasons people get in touch are water that shows only in certain storms and damp patches next to the stack.
Water getting into a London home often comes from a detail you cannot see from the street: a butterfly roof’s central valley gutter, a parapet gutter, a chimney flashing or a flat roof over a back addition. Whether you’re tracing a leak or recording storm damage in Bow, those are among the first places to look. Water from a hidden gutter can run along joists and show up a room or two away.
The report works through the roof section by section, from the main slopes down to the gutters and outlets, each with a short note and a photo. You’ll see the good as well as the bad.

Roof leak investigations in Bow: local notes
Sutton House, about 1.6 miles north-west, is one of the historic houses in the wider area around Bow. If your house is among the older ones, expect a mix of original materials and later repairs on the roof. Many homes in inner London are Victorian and Edwardian terraces, often with Welsh slate roofs. From the street you may see only a parapet, with a butterfly roof and a valley gutter behind it draining to the back. In a house like that, shared stacks, party-wall upstands and lead flashings all need looking at as far as they can be seen. Different coverings let water in at different points, which shapes where the search starts.
For site and facilities teams at buildings like Old Ford Primary - A Paradigm Academy, on a building that size, finding the source of a drip means looking well beyond the stain. If you look after a shop, office or commercial unit, for example near Westfield Stratford City, a quick answer on where water is coming in keeps a business running. If your home is one of the older ones in the streets near St Paul Old Ford, leaks on older roofs often start at lead flashings, valleys or around old chimney stacks.

Bow questions
Is Bow in the area you cover?
We do. Every survey there gets the same written report with photos, and visits run on weekdays and weekends.
Is parking a problem for a survey in Bow?
It depends on the street. If Bow has controlled parking where you are, a visitor permit is the easiest answer.
Are you structural engineers?
No. Our survey isn’t a structural engineer’s report. We will recommend an engineer if we see signs that call for one.
Is it a leak or condensation?
Many apparent leaks turn out to be condensation. A leak usually shows in one area and follows rain, while condensation is often spread out and worse in cold weather. We tell you which it is most likely to be.
How long will you be at the property?
It usually takes roughly 1–2 hours, more where the leak is intermittent or the roof is large. The report follows within 48 hours for Basic, 24 to 48 hours for Standard and the same day for Premium.
What happens next?
You will get the report by email, with photos and clear recommendations. With Standard there is a follow-up consultation; with Premium, an in-person consultation, so you can talk the findings through.
Can you always find the source?
Not every leak can be pinned down in a single visit. Most leave clues we can follow, but some only appear in certain weather. The report sets out what we found and the most likely routes.
Landlord and commercial surveys in Bow
Buyers’ agents can book surveys on behalf of their clients. The report is emailed, so it can go straight to your client.
If you own several properties, you can book surveys for several addresses. To discuss a number of properties, phone 07833 053749 or email us.
Why act early in Bow
Wet insulation does not insulate well. Insulation can soak up water quietly before anything shows below. Catching it early limits what has to be replaced. Blocked gutters and hoppers on London houses overflow and soak brickwork. A small blockage left for a few winters becomes a damp problem.
Simple, low roofs take less time to survey than tall or complicated ones, and the package matters as well. The price is always agreed first.

What affects the cost of roof leak investigations
Every roof is different, so prices are confirmed before booking. This is what makes a difference:
- Height and safe access
- If the survey needs thermal imaging or a drone
- The shape of the roof and its details
- The package you choose: Basic, Standard or Premium
Our price is from £150, including VAT. What you pay depends on how big and how high the roof is, access and the package you choose.
Booking your survey
Getting the details right at the start saves time. It’s useful to include:
- Photos of the roof, taken safely from the ground or a window
- Dates you are working to, such as exchange
- Where the property is, with the postcode
- The reason for the survey, such as buying, a leak or storm damage
To book a survey, call 07833 053749 or use the contact form and tell us the address and what’s prompted the survey. You will know the price before anything is booked.
How the survey changes by roof type
Slate and tile slopes
On slate roofs, corroded nails let slates slip. One slipped slate can be enough to cause a leak.
Lead flashings
Wherever a roof meets a wall or stack, a flashing keeps rain out. We check for lead that has lifted, split or slipped, and for flashings that have been patched with bitumen.
What happens on the day
Once we have finished looking, we write up our findings in a report with photos. As for time on site, most surveys take about one to two hours for most homes, though a hard-to-trace leak can take longer. London terraces rarely offer a view of the whole roof from one spot, so in Bow we work round the house, using the street, the windows, the loft and any safe vantage point behind it. Shared stairs or a basement flat? Let us know who holds the keys.
- 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 is 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
- Have any paperwork from past roof work to hand
- If you’re buying, check with the agent that we can get in
- Clear the way to the loft hatch
Booking a survey
We survey roofs seven days a week. To find a date that works for you, call 07833 053749 or use the contact form.
Related advice
Before and after the survey
A little preparation and a few simple habits help, both for the survey and for the roof itself. Our tips:
- Keep a photo record of the damp patch
- Stay off ladders and the roof
- Let us know if there are tanks or pipes in the loft
- Note the weather when the leak shows
Where we find more than one possible route, we say which is most likely and why. We say which items need prompt attention, so you know what to deal with first.
Keep gutters, valleys and outlets clear, particularly in autumn. Many leaks start with a blocked outlet. Leave the clearing to someone with the right equipment.
