Old Coulsdon Roof Leak Investigation
Roof leak investigations around Old Coulsdon, with a written report you can act on. Book a weekday or weekend visit.
- Damp underlay across a wide area
- A leak that comes and goes with the weather
- Damp walls below an overflowing gutter
What happens on the day
Photos are taken throughout the visit, so the report shows exactly what we saw. Close-ups come from the safest viewpoint available. Most surveys take between one and two hours at a typical home, though large, tall or awkward roofs take more time. In converted houses and mansion blocks, the loft hatch is often on a shared landing. Where that’s the case, access needs agreeing with whoever controls that landing. Otherwise, the visit in Old Coulsdon runs like any other.
- We start with what you’ve seen: where the stain is and when it gets worse.
- The visit starts indoors, at the stain and in the loft.
- We check the likely entry points outside, such as flashings, valleys, chimneys and gutters.
- Moisture readings and thermal imaging are used where they help.
- Your report sets out where the water is most likely getting in, with photos and recommendations.
Preparing for the visit
- Make sure the loft hatch can be reached
- If you’re buying, check with the agent that we can get in
- Make a note of anything you’d like us to look at

Roof leak investigations for homes and businesses in Old Coulsdon
Our job is to find the likely source and tell you. The report shows, with photos, where we believe the water gets in and how it travels, and recommends what should be done. Whoever does the work then has a clear starting point. The investigation finds and explains the cause, and the repair itself is a separate job. If you are worried about damp walls below an overflowing gutter and leaks that appear only in driving rain, we can find out what’s behind it, on valleys and parapet gutters, lead flashings and slate and tile slopes alike.
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. For a leak or storm damage in Old Coulsdon, those hidden details are where the inspection begins. Water from a hidden gutter can run along joists and show up a room or two away.
Report times depend on the survey you book: Basic within 48 hours, Standard in 24–48 hours and Premium the same day.

Before and after the survey
Over many surveys, some simple habits stand out as worth the effort:
- Stay off ladders and the roof
- Let us know if there are tanks or pipes in the loft
- Write down the wind direction and rain when it leaks
- Take dated photos of the leak
The report gives whoever carries out the work a clear starting point. They’ll see exactly where the problem is, 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. Small faults dealt with quickly rarely become leaks.
Wind, rain and roofs in Old Coulsdon
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. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Each of these roof types has its own typical places for water to get in. About 5 miles north-east lies Addington Palace, a reminder of how long the area around Old Coulsdon has been built on. If you own one of the older houses, expect a mix of original materials and later repairs on the roof.
Trees in and around Dollypers Hill shed leaves that can end up in nearby gutters. Take a building like Keston Primary School: water through a big roof can travel a long way before it drips, so the search covers more than the obvious spot. If you own a rental within reach of Coulsdon South station, a clear finding on where water gets in helps you brief a roofer straight away.

Should I look at the roof myself first?
A DIY look is useful, but it is not a survey. You won’t see flashings, valleys or the backs of chimneys properly from ground level.
It helps to keep a record: dates of leaks, photos from the ground and any work done on the roof. Send it with your enquiry and it will help the survey.
What affects the cost of roof leak investigations
Prices vary from roof to roof, for these reasons:
- How big the roof is
- The number of roofs, including extensions and garages
- House, block, shop or office
- Basic, Standard or Premium
The cost of a survey depends on the roof: its size, its height, how many sections it has and how it can be reached and seen safely. Our price is from £150, including VAT.
Getting in touch
A little information up front helps. Please include:
- The kind of building and roof involved
- Dates you’re working to, like exchange
- The property’s address and postcode
- What made you get in touch
We confirm the price for the job before booking, so you know where you stand. Roof leak investigation starts from £150, including VAT. To book, ring 07833 053749 or drop us an email.
Old Coulsdon: your questions answered
Do you cover Old Coulsdon?
Yes, Old Coulsdon is within the area we cover. We cover the whole of London and South East England. You can ring 07833 053749 or send us an email with the address and some details.
Does a conservation area affect roof work in Old Coulsdon?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it’s in a conservation area. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
What should I do before you arrive?
Make sure the loft can be reached. Gather any photos and notes about when it leaks, plus details of past repairs. Keep catching drips and keep water away from electrics.
Can you find a leak when it isn’t raining?
In most cases, yes. Moisture detection shows where materials are damp even on a dry day. For leaks that only happen in certain storms, we report the most likely routes.
What do I do with the report?
You’ll get the report by email, with photographs and clear recommendations. The Standard Survey includes a follow-up consultation, and the Premium Survey an in-person consultation.
How long have you been surveying roofs?
Over 20 years and more than 5,000 surveys, across London and South East England.
Can you inspect my roof with a drone?
Where it helps and the rules allow, yes. Our sub-250g drone is flown by a CAA-registered operator with a Flyer ID and Operator ID, and the airspace and weather are checked before every flight.
Landlord and commercial surveys in Old Coulsdon
Freeholders and residents’ companies use a roof report to plan and budget.
We survey roofs for landlords and agents as well as householders. The report gives you a dated record of the leaking roof, with photographs.
Why it’s worth a survey now in Old Coulsdon
If a leak has been ‘fixed’ before and has come back, the cause was probably missed. We look past the obvious spot and check each likely route. It gives the next repair a far better chance. Any roof job in Old Coulsdon means planning around parking, neighbours and access. That is a good reason to find problems early, while there’s time to plan, rather than in a rush after a leak.
One thing that affects the price is the package: Basic from £150, Standard from £250 or Premium from £400, all including VAT. The roof’s size, height and access matter as well.
