Roof leak investigations for homes and businesses in South Ruislip
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. We check each likely route and follow the evidence. Chimneys, dormers and roof lights each add joints of their own. Each one is looked at from wherever it’s safe to see it. We survey flat roof details, chimney stacks and the roof space, and people most frequently book us about drips from nail tips in a cold loft and damp on a chimney breast.
London’s Victorian and Edwardian roofs have frequently been repaired many times, so a new leak can be the latest sign of wear rather than a single event. Insurers normally exclude wear and tear, so it helps to know whether damage is old or new. That is as true in South Ruislip as anywhere in London. A written record with photographs helps you explain what was found to whoever deals with it next.
The report is yours to share with whoever needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent, whichever applies.

Tips from our surveys
Some practical points come up on survey after survey. They’re worth knowing whatever the roof:
- Write down the wind direction and rain when it leaks
- Keep a photo record of the damp patch
- Check the loft is accessible
- Leave roof access to professionals
Keep the report after the work is done. If water appears again, it shows what was found before, which makes the next step quicker.
Look at the roof from ground level after strong winds. Pieces of slate or tile in the garden mean something has moved. Prompt repairs stop gaps turning into leaks.

Questions from South Ruislip
Do you cover South Ruislip?
Yes. We work right across London and the South East, and South Ruislip is part of that. Just ring 07833 053749 or drop us an email and let us know about the property.
Does a conservation area affect roof work in South Ruislip?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. The answer matters most when a change of material is on the cards.
How long does the visit take?
On site, it usually takes about one to two hours for most homes, though a hard-to-trace leak can take longer. The report follows within 48 hours for Basic, 24 to 48 hours for Standard and the same day for Premium.
Do you use thermal imaging to find leaks?
Thermal imaging is used where it’s useful, and it’s included in our Premium Survey. It shows temperature differences, not water itself, so anything it suggests is checked with moisture readings.
Can every leak be traced?
Not every leak can be pinned down in a single visit. Most leave clues we can follow, but some only appear in certain weather. The report sets out what we found and the most likely routes.
Is the repair included in the leak investigation?
The investigation is about finding the cause. The repair itself is a separate job. You get a report with photos showing where the water is getting in and what needs attention, which whoever carries out the work can follow.
Is it the same as a RICS Level 2 or Level 3 survey?
No. Our survey is a roof survey, not a RICS Level 2 or Level 3 survey of the whole building. It focuses on the roof, so it sits alongside a building survey rather than replacing it.
What a survey costs
Prices always include VAT. What changes the price is:
- House, block, shop or office
- Any need for thermal images or a drone flight
- Extensions, dormers and garages with roofs of their own
- Chimneys, valleys, parapets and other details
Our price is from £150, including VAT. Packages run from Basic at £150 through Standard at £250 to Premium at £400, inc. VAT.
What we need to know
There’s no need for technical words. It is enough to let us know:
- How the loft is reached, if there is one
- Pictures from the garden or a window, if you have them
- What kind of property and roof it is
- The reason for the survey, such as buying, a leak or storm damage
Our phone lines are open seven days a week. To book or ask a question, phone 07833 053749 or use the contact form.
What we are asked to look at in South Ruislip
A gutter that overflows can soak a wall and mark the ceiling inside. Parapet and box gutters are the worst for this, because when they block, water backs up and runs inside.
A survey can pick up problems such as:
- Leaks at a dormer or roof window
- Wet patches on loft insulation
- Drips from nail tips in a cold loft
- Leaks below a flat extension roof
If you run a business near St. George's Shopping Centre, water through a ceiling can damage stock and close a sales floor, so the source needs finding fast.
Before you book anyone
- What’s outside the scope of the survey
- Whether any drone flown is registered with the CAA
- What insurance they carry
- How much experience they have with roofs like yours

Roof leak investigations in South Ruislip: local notes
Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, frequently with hipped roofs of clay or concrete tiles. 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 South Ruislip has a long history of building, with Northolt Manor about 1.4 miles south-east. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and any change of roofing material on a listed home needs checking with the council first.
For landlords with property near South Ruislip station, finding the cause of a leak fast keeps a tenant’s home dry and the work focused. If you live near a park such as Northala Fields, or anywhere with mature trees, autumn leaves can block gutters and valleys, so outlets and downpipes are worth watching.

How the survey works
Safety comes first on every visit. We inspect everything that’s safely in view, and anything we can’t see is noted in the report. The survey typically takes roughly 1–2 hours, more where the leak is intermittent or the roof is large. Many London properties are flats or terraces with no side access, so the back of the roof is often seen from upstairs windows, from inside or, where a flight is allowed, from the air. If the building has a managing agent or access rules, let us know when you book.
- You get in touch with details of the leak and any photos.
- The visit starts indoors, at the stain and in the loft.
- We check the likely entry points outside, like flashings, valleys, chimneys and gutters.
- Moisture readings and thermal imaging are used where they help.
- You receive a written report with photos showing the likely source and what needs attention.
Before we arrive
