Roof Leak Investigation in Southwark
Tracing where water is getting into your roof across Southwark, with drones and thermal imaging where they help. Call or email for a price.
- Damp underlay across a wide area
- Staining where a gutter or parapet meets the wall
- A leak that comes and goes with the weather
Southwark roofs and the weather
Historic houses such as Mansion House, about 0.9 miles north, show how far back building in the area around Southwark goes. 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. Lead flashings, party-wall upstands and shared chimney stacks are typical of these houses, if yours is one of them. The covering and its details give the first clues when tracing where water is coming from.
Take a building like Charles Dickens Primary School: a leak through a large roof is frequently found some distance from where the water shows inside. Landlords with a home close to Elephant & Castle station may find that tracing a leak quickly matters when a tenant is living with it.
Southwark is about 0 miles north-west of London, in Greater London. In Southwark, as across Greater London, every roof gets the same careful survey. Southwark is one of the places in Greater London we cover for roof leak investigations.

About our roof leak investigation in Southwark
The aim is to find where the water is getting in and explain it. The report shows, with photos, where we believe the water gets in and how it travels, and recommends what should be done. It gives any roofer a clear brief. We find and report the source, while the repair is a separate matter. We survey lead flashings, chimney stacks and slate and tile slopes, and common reasons people get in touch are stains around a skylight and damp underlay across a wide area.
Many London homes are well over a century old and their roofs have been patched more than once. Telling wear from a one-off event matters, because insurers usually exclude wear and tear. That’s as true in Southwark as anywhere in London. Photographs and a written account give you something specific to show an insurer, a landlord or a roofer.
We keep jargon out of it: where something needs attention, it says so plainly, along with how urgent it is.

Surveys for landlords and agents in Southwark
Roof problems in a rented home affect tenants as well as the building. A survey helps you spot issues early and plan the work around your tenants.
For blocks of flats, a roof survey helps managing agents and residents’ management companies plan ahead. Recommendations are set out by urgency where it matters.
How the survey works
On the day, we begin with a quick chat about the roof and anything that’s worrying you. After that, we check everything we can see safely, using the ground, windows, the loft and a drone where applicable. The survey typically takes about one to two hours on an ordinary house, and about three to four hours for a commercial roof. Many London properties are flats or terraces with no 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. If the building has a managing agent or access rules, let us know as you book.
- We help you choose the package that suits the leak.
- A visit is booked for a weekday, Saturday or Sunday.
- The investigation works from the stain back to the roof.
- Where it’s useful and included, we take moisture readings and use thermal imaging.
- You get photos, the likely cause and clear recommendations.
Before the survey
- Let us know about parking near the property
- If the roof is shared, arrange access with whoever manages the building
- Have any paperwork from past roof work to hand
Arrange a survey
Buyers should book once an offer has been accepted, so there’s time to use the report before exchange. Otherwise, simply ring 07833 053749 or drop us an email whenever suits you.

Signs you need a roof leak investigation in Southwark
A chimney stack has a good many places for rain to get in. Water can enter through crumbling mortar, cracked flaunching, worn flashings or uncapped pots. It can show up on the chimney breast, nearby ceilings or in the loft space.
Here are some of the things we see often:
- Ceiling stains that grow after rain
- Damp walls below an overflowing gutter
- Damp ceilings under a flat roof
- Condensation that looks like a leak
For businesses in and around places such as Gabriel's Wharf, a quick answer on where water is coming in keeps a business running.
Before you book any roof surveyor
- Their insurance cover
- Whether any drone flown is registered with the CAA
- Will they check the loft as well as the outside?
- What the report includes, and whether it has photographs
Southwark questions
Is Southwark in the area you cover?
Yes, Southwark is within the area we cover. We survey roofs across London and the South East. You can phone 07833 053749 or email us with the address and some details, and we will talk through which survey suits.
Will parking be an issue for a roof survey in Southwark?
Sometimes, yes. If Southwark has controlled parking where you are, a visitor permit is the easiest answer.
Which days do you carry out surveys?
We survey seven days a week: Monday to Friday, Saturdays and Sundays. Just let us know the days that suit you.
Why doesn’t the damp patch line up with the hole?
Rain that gets in will run along whatever it lands on. On a flat roof it can travel under the covering before it finds a way through the ceiling. Tracing that path is the heart of a leak investigation.
How long have you been surveying roofs?
More than 5,000 surveys over 20+ years.
Does the report include photos?
Yes. Photos are part of every report, so you can see each point for yourself.
Is it the same as a RICS Level 2 or Level 3 survey?
No. Our survey looks at the roof, not the whole building. If you need a full building survey, you will need a RICS survey as well.
What a survey costs
Not every roof costs the same to survey, and it comes down to:
- How complicated the roof is, with its valleys, chimneys and parapets
- The number of roofs, including extensions and garages
- How big the roof is
- House, block, shop or office
To find out what your survey will cost, ring 07833 053749 or use the contact form and let us know about the roof. The price is agreed before a date is set.
Booking your survey
A few details help us point you to the right survey and price. When you contact us, it helps to mention:
- Pictures from the garden or a window, if you have them
- The address and postcode of the property
- How the loft is reached, if there is one
- The reason for the survey, like buying, a leak or storm damage
We confirm the price for the job before booking, so you know the cost up front. Roof leak investigation starts from £150, including VAT. To book, phone 07833 053749 or email us.
Useful tips for Southwark property owners
A little preparation and a few simple habits help. Our tips:
- Photograph the stain each time it appears
- Put a bucket under the drip and move valuables
- Mention earlier attempts to fix the leak
- Tell us if there are tanks or pipes in the loft
Standard includes a follow-up consultation to talk the findings through, while Premium includes one in person. You can ask us about anything that is not clear.
Keep the roof space ventilated. Good airflow reduces condensation, and condensation is a common false alarm. Check insulation does not block airflow at the eaves.
Why get it checked now?
Patching the spot above the stain frequently doesn’t work. The real way in may be a metre or more away. We find the probable source before anyone starts work. Blocked gutters and hoppers on London houses overflow and soak brickwork. A small blockage left for a few winters becomes a damp problem.
All our prices include VAT. Our price is from £150, including VAT. You’ll know the price for your survey before you book.
