Roof leak investigation in Bishopsgate: what you get
Older homes have more places for water to get in. 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. We check parapets, valleys and flashings from every safe viewpoint. Our report shows what we found, with photos. We survey chimney stacks, rooflights and dormers and slate and tile slopes, and the problems we are asked to look at most are water through the ceiling under a flat roof and staining where a gutter or parapet meets the wall.
Water getting into a London home often 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. Whether you’re tracing a leak or recording storm damage in Bishopsgate, those are among the first places to look. A hidden gutter that overflows can send water a long way before it shows.
Report times depend on the survey you book: the Basic Survey within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey on the same day.

Before and after the survey
A survey works best with a little help from you, before and after. Tips:
- Protect furniture and flooring under the leak
- Take dated photos of the leak
- Note the weather when the leak shows
- Stay off ladders and the roof
Standard includes a follow-up consultation to talk the findings through, while Premium includes one in person. You can ask us about anything that isn’t clear.
Keep the roof space ventilated. Air movement keeps condensation down, and condensation is a common false alarm. Keep insulation clear of the eaves.
Wind, rain and roofs in Bishopsgate
The wider area around Bishopsgate has a long history of building, with Mansion House about 0.4 miles south-west. 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 the council can say whether a home is in a conservation area. Welsh slate on Victorian and Edwardian terraces is a familiar sight across inner London. Many have butterfly roofs draining to a central valley gutter, with parapet walls and gutters hidden behind them. In a house like that, shared stacks, party-wall upstands and lead flashings all need looking at as far as they can be seen. Where water gets in depends a good deal on what the roof is made of and how it’s detailed.
If you own a rental within reach of London Liverpool Street 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 The London School of Barbering, water through a big roof can travel a long way before it drips, so the search covers more than the obvious spot. Homes near green spaces such as Finsbury Circus can get more leaves in their gutters in autumn, so outlets and downpipes are worth watching.
Bishopsgate is about 1 mile north-east of London, in Greater London. Houses, flats, blocks and commercial buildings in Bishopsgate can all book roof leak investigations, with a written report and photographs every time. Our Greater London coverage includes Bishopsgate and the places around it.

Different roofs, different checks
Parapet and box gutters
Hidden gutters run behind parapets or between roofs. When their outlets block, water rises over the lining and runs indoors.
Flat roof upstands and outlets
Upstands seal the edge of a flat roof where it meets a wall. A low or cracked upstand is a common way in.
Honest limits
Our findings are based on what we can see safely on the day, so some things are outside what a survey can do:
- Plumbing leaks that look like roof leaks
- Structural calculations (that’s a structural engineer’s job)
- An intermittent leak that shows no trace on the day

Yes, Bishopsgate is one of the places we work. Every survey there gets the same written report with photos, and visits run on weekdays and weekends.
Will parking be an issue for a roof survey in Bishopsgate?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available as you book.
How long does a roof leak investigation take?
Allow about one to two hours for most homes, though a hard-to-trace leak can take longer. We’ll give you an idea of timing as you book.
What’s the best way to book?
The quickest way is to call 07833 053749 or use the contact form. Give us the address and a few details about the roof. Surveys run on weekdays, Saturdays and Sundays.
Do you take photos of the roof?
Yes, every report has them. Pictures sit next to the findings they show, so you can see what we mean.
When does the report arrive?
Each package has its own report time. Basic is within 48 hours, Standard is 24–48 hours and Premium is the same day. Mention any deadline as you book.
Will you fly a drone over my roof?
Where it’s applicable and safe, yes. We are a CAA-registered drone operator (Flyer ID and Operator ID), flying a sub-250g drone. Drone inspection is part of the Drone Roof Survey and the Premium Survey, where applicable.

What affects the price in Bishopsgate

Our price is from £150, including VAT. What you pay depends on how big and how high the roof is, how it can be seen safely and the package you choose.

DIY checks: what’s safe
Inside, the loft is a good place to look, with care. Use a torch and stay on the joists or boards, checking for stains, damp wood or chinks of daylight.
Look up at the roof after a storm, from the ground: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Do not go up yourself.
How the survey works
The visit has one job: to see as much of the leaking roof as can be seen safely and record it clearly. Notes and photos go into the written report. The visit normally takes an hour or two, more where the leak is intermittent or the roof is large. In converted houses and mansion blocks, the loft hatch is often on a shared landing. If that applies to your building, it helps to agree access with the neighbours or the managing agent first. Everything else is planned around the building, not the postcode.
- You tell us where the water shows and when it appears.
- Inside, we check the damp area and the roof space above it.
- Outside, we look at every likely route in.
- Where it helps, we take moisture readings and use thermal imaging.
- You receive a written report with photos showing the likely source and what needs attention.
Before the survey
- Mention any parking restrictions on your street
- Leave side gates unlocked
- If you are buying, check with the agent that we can get in
