How we price roof leak investigations
Our packages start from £150, inc. VAT. The price for your roof depends on:
- How tall the building is and how easy the roof is to see
- Commercial roofs and larger buildings
- How complicated the roof is, with its valleys, chimneys and parapets
- Roof area
A small, low roof with good viewpoints takes less time than a tall, complicated one, and the package matters as well. We will give you the figure before anything is booked.

Roof leak investigations for homes and businesses in North Cray
We use moisture detection and thermal imaging where they help. Moisture readings show which materials are wet. A thermal camera shows patterns of temperature rather than water, so we confirm what it suggests with moisture readings. Thermal imaging is part of the Premium Survey, and moisture detection comes with Standard. Thermal imaging works best after a sunny day, on a dry roof with little wind. Common reasons to book are water dripping from rafters or underlay and water through the ceiling under a flat roof, on flat roof details, lead flashings and chimney stacks.
Many London homes are well over a century old and their roofs have been patched more than once, so a new leak can be the latest sign of wear rather than a single event. Insurers usually exclude wear and tear, so it helps to know whether damage is old or new. A careful look in North Cray 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.
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.

Leaks and storm damage in North Cray
Further from the centre, London’s housing takes in interwar semis with hipped roofs in clay or concrete tiles as well as slate-roofed terraces. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Where water gets in depends a good deal on what the roof is made of and how it is detailed. The wider area around North Cray has a long history of building, with Hall Place and Gardens about 1.4 miles north-east. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and a listed home or one in a conservation area may need consent for changes of material.
Landlords with a home close to Albany Park station may find that tracing a leak quickly matters when a tenant is living with it. If you live in an older home near Parish Church of St James, leaks on older roofs often start at lead flashings, valleys or around old chimney stacks. For businesses in and around places such as Broadway Shopping Centre, water through a ceiling can damage stock and close a sales floor, so the source needs finding fast.
North Cray is about 2 miles east of Sidcup, in Greater London. Anywhere in North Cray, we can carry out roof leak investigations at your property, on a weekday, Saturday or Sunday. Our area takes in places right across Greater London, large and small. You can also see our page for London.

Tips that help
Some practical points come up on survey after survey. They apply to most roofs:
- Do not climb onto the roof to look
- Protect furniture and flooring under the leak
- Let us know if there are tanks or pipes in the loft
- Photograph the stain each time it appears
Keep the report after the work is done. If water appears again, it shows what was found before.
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.
Should I look at the roof myself first?
Your own check is a good start, but it is not 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.
You can learn a lot from ground level. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Please do not climb up for a closer look.
What this survey can’t tell you
To be straight with you, a roof survey has limits:
- An intermittent leak that shows no trace on the day
- What’s under the covering or behind the plaster
- Carrying out the fix

Questions from North Cray
Does a conservation area affect roof work in North Cray?
We can’t confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case, and councils can also use Article 4 directions.
Can parking be tricky for a visit in North Cray?
Sometimes, yes. Where there are permit zones, a visitor permit or nearby pay-and-display bay works well.
How fast do I get the report?
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.
Are you structural engineers?
No. We point out what can be seen, like sagging or deflection, but we don’t carry out calculations or give an engineer’s opinion. If we think you need an engineer, the report says so.
Why isn’t the leak directly above the stain?
Because water travels. It runs along rafters, battens or underlay before it drips, so the entry point is frequently well away from the mark. That is why we trace the route rather than patching above the stain.
Does the investigation include the repair?
The investigation is about finding the cause. The repair is not part of it. You get a report with photos showing where the water is getting in and what needs attention.
What happens next?
We email you the written report with photos and recommendations. You can use it to talk to a seller, an insurer, a roofer or a managing agent, whichever applies.
How the survey works
You do not need to do much on the day. Show us any stains, drips or problem areas you know about, and we’ll get on with the inspection. A typical survey takes between one and two hours for most homes, though a hard-to-trace leak can take longer. In North Cray, as in much of London, a good many properties are flats or terraces without side access, so rear slopes are viewed from windows, the loft or, where a flight is allowed, by drone. Mention any building rules, key holders or managing agents as you book.
- You let us know where the water appears, when, and what the weather was doing.
- We examine the damp area and the rooms near it.
- From the roof space, we trace the water’s route where there is safe access.
- We inspect the likely entry points outside, from ground level, windows and the roof where safe.
- You receive a report with the likely source, photos and recommendations.
Before we arrive
- Clear the way to the loft hatch
- Let us know about parking near the property
- Have keys ready for side gates, garages or roof access doors
