About our roof leak investigation in Deptford
We use moisture detection and thermal imaging where they help. Moisture readings show which materials are wet. Thermal imaging shows temperature differences that can point to wet areas, not water itself, so its findings are checked with moisture readings. Moisture detection is included in the Standard Survey, and thermal imaging in Premium. Thermal imaging works best after a sunny day, on a dry roof with little wind. We survey the roof space, chimney stacks and flat roof details, and common reasons people get in touch are wet patches high on an inside wall 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. Insurers typically exclude wear and tear, so it’s useful to know whether damage is old or new. A careful look in Deptford tells the two apart where the evidence allows. Photographs and a written account give you something specific to show an insurer, a landlord or a roofer.
You can share the report with anyone who needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent.

The survey, step by step
Where it is relevant and can be reached safely, the roof space is checked as well as the outside. In the loft, the signs we look for are staining, damp, daylight and sagging. The whole visit normally takes between one and two hours for most homes, though a hard-to-trace leak can take longer. From the street, a London terrace typically shows only its front slope or parapet, so a visit in Deptford moves between viewpoints: the pavement, upstairs windows, the loft and any safe spot at the back. If other people live in the building, let us know who can let us into the shared parts.
- You tell us where the water appears, when, and what the weather was doing.
- Inside, we check the stain and the ceiling around it.
- From the loft space, we trace the water’s route where there’s safe access.
- We inspect the likely entry points outside, from the ground, windows and the roof where safe.
- We email a written report showing where the water most likely gets in.
Getting ready for the survey
- Have any paperwork from past roof work to hand
- Tell us where we can park nearby
- Unlock side gates and any roof access doors

How we price roof leak investigations
Survey packages start from £150, with VAT included. What you pay for your roof depends on:
- How complicated the roof is, with its valleys, chimneys and parapets
- Building height and the viewpoints available
- The package you choose: Basic, Standard or Premium
- If the survey needs thermal imaging or a drone
Every price we give includes VAT, and the report isn’t charged as an extra. Prices start from £150, including VAT. Where your roof sits in the range depends on its size, height and access.
Booking your survey
Getting the details right at the start saves time. It helps to include:
- The style of property, from a terrace to a block
- Where any leaks, stains or damp patches show inside
- Whether there’s a loft hatch, a shared roof or tricky access
- What made you get in touch
We survey roofs on any day of the week. To find a date that works for you, call 07833 053749 or use the contact form with the address and the days you’d prefer.
For landlords and managing agents

We survey roofs for letting agents and landlords as well as homeowners. The report gives you a dated record of the leaking roof, with photographs, which helps you plan work between tenancies.
When to book a survey in Deptford
Slipped or missing slates and tiles let rain reach the underlay. Ageing felt underlay eventually tears and lets water through, and very old roofs may have no underlay at all. Corroded nails, known as ‘nail fatigue’, are a frequent cause on slate roofs.
Here are some of the things we see often:
- Leaks that appear only in driving rain
- Leaks at a dormer or roof window
- Wet patches high on an inside wall
- Brown rings on upstairs ceilings
For businesses in and around places such as Lewisham Shopping Centre, water through a ceiling can damage stock and close a sales floor, so the source needs finding fast.
Choosing a roof surveyor
- Their insurance cover
- Whether the inside of the roof is included
- Whether any drone flown is registered with the CAA
- What the report includes, and whether it has photos
FAQs for Deptford
How do I find out if my home in Deptford is listed?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it’s worth checking before planning any.
Can parking be tricky for a visit in Deptford?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly.
Will you definitely find the leak?
We can’t promise to find every leak on one visit. Many leave clear signs, but some only appear in certain weather. The report sets out what we found and the most likely routes.
What’s the best way to book?
Just phone 07833 053749 or email us. We will ask a few questions, confirm the price and agree a date, weekday or weekend.
Do you test for asbestos?
No. We do not carry out asbestos surveys or testing. We flag materials that could contain asbestos, such as cement sheets or soffits on pre-2000 buildings, and recommend a specialist asbestos surveyor checks them before they’re disturbed.
Can thermal imaging help find my roof leak?
Where conditions suit, it can. It works best after a sunny day, with a dry roof surface and little wind. Wet insulation holds heat longer than dry, which can show up on the image. Its findings are confirmed with a moisture check.
What does a roof survey cost?
Prices start from £150, including VAT. You will know the exact price before booking. To get a price, call 07833 053749 or drop us an email.
Can I check my roof myself?
A DIY look is useful, but it isn’t a survey. You won’t see flashings, valleys or the backs of chimneys properly from the ground, and those are details a survey looks at closely.
After strong wind, take a look from the pavement or garden: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Do not go up yourself.

Other services in Deptford
Different roofs, different checks
Flat roof upstands and outlets
Upstands seal the edge of a flat roof where it meets a wall. If it is too low, cracked or poorly dressed, water gets behind it.
Lead flashings
Mortar fillets are sometimes used instead of lead. They crack as the roof and wall move, and water runs down behind them.
Roof leak investigations around Deptford
Historic houses such as Queen's House, about 1 mile east, show how far back building in the area around Deptford goes. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead. Welsh slate on Victorian and Edwardian terraces is a familiar sight across inner London. Behind many of their parapets sit butterfly roofs and valley gutters that cannot be seen from the pavement. 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 is detailed.
For landlords with property near Deptford station, tracing a leak quickly matters when a tenant is living with it. Trees in and around Sue Godfrey Nature Park shed leaves that can end up in nearby gutters.
