About our roof leak investigation in St Pancras
Most roof leaks start at a joint rather than the middle of a slope. 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 we follow where the evidence leads. Chimneys, dormers and roof lights each add joints of their own. We look at all of them, from every safe vantage point. Common reasons to book are water dripping from rafters or underlay and damp patches next to the stack, across valleys and parapet gutters, the roof space and slate and tile slopes.
In London, leaks often start somewhere hidden: the valley gutter in a butterfly roof, a parapet gutter, a chimney flashing or the flat roof over a rear extension. Whether you are tracing a leak or recording storm damage in St Pancras, 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.
You can share the report with anyone who needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent.

Common roof problems in St Pancras
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. Once that seal cracks or lifts, water gets behind it, often well away from where it shows.
We’re often asked to look at:
- A leak that comes and goes with the weather
- Leaks below a flat extension roof
- Wet patches high on an inside wall
- Leaks at a dormer or roof window
If you run a business near Brunswick Centre, water through a ceiling can damage stock and close a sales floor, so the source needs finding fast.
Choosing a roof surveyor
- What experience they bring
- Is VAT included in the price?
- Their drone registration, if they fly one
- What’s outside the scope of the survey
How the survey works
The aim of the visit is simple: to look at the leaking roof as closely as is safe and record what we find. Notes and photos go into the written report. It normally takes roughly 1–2 hours at a typical home, with bigger or more complicated roofs taking longer. Surveys in St Pancras can be booked for any day of the week. It helps if you can point us to a visitor permit or a nearby bay, and to clear a path to the loft hatch. Upstairs rooms at the back are useful too, as they often give the best view of a rear addition.
- We start with your notes and photos of the leak.
- Inside, we look at 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.
- You receive a report with the likely source, photos and recommendations.
Getting ready for the survey
- Tell us about parking before the day
- Find any records of previous roof work
- Make sure we can get to the back of the property
Booking a survey
If you have photos of the roof, send them over. Pictures from the ground or a window are fine. To send them or to book, ring 07833 053749 or drop us an email.

What affects the price in St Pancras
The price reflects the time and kit the roof needs. That comes down to:
- Commercial roofs and larger buildings
- How complicated the roof is, with its valleys, chimneys and parapets
- Extra roofs, like extensions, dormers or garages
- The package you choose: Basic, Standard or Premium
Roof leak investigation starts from £150, including VAT. The final price depends on how big and how high the roof is, access and the package you choose.
What to tell us when you contact us
You do not need to know any roofing terms. Just tell us:
- Whether there’s a loft hatch, a shared roof or tricky access
- What made you get in touch
- When you need the report by
- The address and postcode of the property
Most bookings start with a short call: ring 07833 053749 or use the contact form, and we will ask about the building and what you need. You’ll have a price before anything is arranged.
Surveys for landlords and agents in St Pancras
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.
We survey roofs for letting agents and landlords as well as householders. A written report with photos gives you a clear record of the leaking roof, useful for planning maintenance.
Common questions in St Pancras
Do you cover St Pancras?
Yes, St Pancras is one of the places we work. The survey and report are the same in St Pancras as anywhere else, and visits run on weekdays and weekends.
Will parking be an issue for a roof survey in St Pancras?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
How soon will I get the report?
Basic reports arrive within 48 hours, Standard reports in 24–48 hours and Premium reports on the same day. All of them come by email.
Can you tell me if my roof has asbestos?
No. We don’t sample or test for asbestos. Where a material might contain it, like old cement sheets on a building from before 2000, the report flags it.
Will I get photos?
Yes, every report has them. Each finding is shown in a picture where possible.
I live in a flat. Can you survey the roof?
Yes. Shared roofs just need a little more planning. Tell us about it when you book and we’ll explain what’s needed.
Can you find a leak when it is not raining?
In most cases, yes. Moisture detection shows where materials are damp even on a dry day. If a leak only appears in driving rain from one direction, we will tell you what we found and what’s most likely.
Leaks and storm damage in St Pancras
The wider area around St Pancras has a long history of building, with Dr Johnson's House about 0.9 miles south-east. Older homes in the wider area frequently have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years, and any change of roofing material on a listed home needs checking with the council first. Inner London’s Victorian and Edwardian terraces frequently have Welsh slate roofs. 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. The covering and its details give the first clues when tracing where water is coming from.
If you let a flat or house near London Kings Cross station, a tenant living with a leak needs the cause found, not just the stain painted over. If you live near a park such as Lincoln's Inn Fields, or anywhere with mature trees, autumn leaves can block gutters and valleys, and blocked gutters overflow and soak walls.

Tips that help
Nothing here needs a ladder. A few suggestions:
- Let us know what has already been tried
- Do not touch fittings that water is reaching
- Keep a photo record of the damp patch
- Write down the wind direction and rain when it leaks
Any roofer you ask to quote can work from the report. The photos show the defects and where they are, rather than at the stain.
After a storm, check the roof from the garden and the street. Slipped slates, lifted ridge tiles and debris on the ground are signs to act on. Prompt repairs stop gaps turning into leaks.
Leave it or get it looked at?
A leak near lights or wiring needs attention quickly. Keep away from any fitting that water is reaching and have an electrician check it. Finding where the water is getting in should follow straight away. Behind a London parapet, a blocked gutter can sit full of water without anyone seeing it. By the time a ceiling stains, the timbers underneath may have been wet for a while.
We offer three survey packages: Basic from £150, Standard from £250 and Premium from £400, with VAT included. What your roof costs depends on its size, access and what you want to find out.
