Roof leak investigations for homes and businesses in Dormers Wells
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. The best thermal results come after a sunny day, with a dry roof and little wind. Typical surveys look at damp underlay across a wide area and damp ceilings under a flat roof, on lead flashings, slate and tile slopes and the roof space.
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 Dormers Wells, those hidden details are where the inspection begins. A hidden gutter that overflows can send water a long way before it shows.
The written findings come by email, easy to pass on to a roofer, an agent or an insurer. Basic reports come within 48 hours, Standard within 24–48 hours and Premium on the day.

What a roof leak investigation looks like in Dormers Wells
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. The wider area around Dormers Wells has a long history of building, with Osterley House about 1.9 miles south. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and any change of roofing material on a listed home needs checking with the council first.
For site and facilities teams at buildings such as Dormers Wells Junior School, a leak through a large roof is frequently found some distance from where the water shows inside. Trees in and around Castle Bar Park shed leaves that can end up in nearby gutters, so outlets and downpipes are worth watching.

What happens on the day
We’ll ask a few questions first, about the roof’s history, any leaks and past repairs. The inspection then takes about 1–2 hours at a typical home, and more on a big or complicated roof. Many London properties are flats or terraces with no 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 when you book.
- We start with your notes and photos of the leak.
- Inside, we check the stain and the ceiling around it.
- From the loft space, we trace the water’s route where there is 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
- Leave side gates unlocked
- Make a note of anything you’d like us to look at
- Point out any leaks or damp patches
How to book
If you’re buying, it is useful to book soon after your offer is accepted, so you have the findings in time to act on them before you exchange. For any other survey, just call 07833 053749 or drop us an email when you are ready.
Advice
Your questions about roof leak investigations in Dormers Wells
Will parking be an issue for a roof survey in Dormers Wells?
Typically it is manageable with a little notice. Let us know the parking rules on your street and we will work around them.
Is my home in Dormers Wells listed or in a conservation area?
The council and Historic England’s list are the places to check. It is worth checking before planning roof work, as both can affect what’s allowed.
Do you carry out surveys on Saturdays and Sundays?
Surveys can be booked for any day of the week: Monday to Friday, Saturdays and Sundays. Tell us which days suit you as you book.
Can you find a leak when it is not raining?
In many cases, yes. Stains, tide marks, damp timbers and moisture readings usually point the way. Some leaks only show in particular weather, so your photos and notes from wet days are very useful.
Is there anything I need to do ahead of the visit?
Make sure the loft can be reached. Gather any photos and notes about when it leaks, and let us know about past repairs. In the meantime, catch the water and keep it clear of lights and sockets.
What insurance do you have?
Every survey is covered by professional indemnity and public liability insurance, and details are available on request.
How long does a roof leak investigation take?
The visit typically takes about one to two hours, more where the leak is intermittent or the roof is large. We’ll confirm what to expect when we arrange the visit.
Rented homes, blocks and businesses
We survey roofs for letting agents and landlords as well as householders. A report with photos gives you a clear record of the leaking roof, which helps you plan work between tenancies.
Managing agents and residents’ management companies use roof surveys to plan maintenance. Recommendations are set out with the most urgent first where relevant, which helps with budgets and planning.
What happens if roof problems are left?
A leak rarely stays small. Wet timbers start to decay, plaster softens and insulation stops working. Finding the source early keeps the damage down. Blocked gutters and hoppers on London houses overflow and soak brickwork. A small blockage left for a few winters becomes a damp problem.
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. The price is confirmed before booking.
Why us?
- Photographs and a written report every time
- Insured for professional indemnity and public liability
- Independent findings on the roof’s condition
- Customer satisfaction of 98%
Honest limits
Some things can’t be seen without opening up the roof, so a survey has limits:
- An intermittent leak that shows no trace on the day
- Defects hidden under coverings or inside walls without opening up
- The repair itself (the investigation finds and reports the cause)

Common roof problems in Dormers Wells
A roof valley collects the rain from two slopes. Worn lead, cracked linings or a build-up of leaves and moss can push water under the slates or tiles. The stain may appear well away from the valley itself.
A survey can pick up problems such as:
- Leaks that appear only in driving rain
- Condensation that looks like a leak
- Damp walls below an overflowing gutter
- Damp on a chimney breast
The streets around a church such as Emmanuel Church are often among the oldest in a place, and if you own one of the older houses nearby, lead flashings, valleys and old chimneys are typical places for water to get in.
Choosing a roof surveyor
- Whether they hold professional indemnity and public liability insurance
- Do they have a CAA Flyer ID and Operator ID for drone work?
- Whether you can ask questions once you have the report
- Will they check the loft as well as the outside?
