What we can’t see
This isn’t a RICS building survey, a structural engineer’s report or an asbestos survey. It also has these limits:
- An intermittent leak that shows no trace on the day
- Structural calculations (that’s a structural engineer’s job)
- Defects hidden under coverings or inside walls without opening up

How a roof leak investigation works in Dancers Hill
Older homes have more places for water to get in. Worn lead, tired valley linings and blocked parapet outlets are frequent causes. A central valley gutter on a butterfly roof frequently turns out to be the source in heavy rain. Parapet walls and their gutters are checked from wherever it is safe. The findings are recorded with photos. Common reasons to book are water dripping from rafters or underlay and water through the ceiling under a flat roof, across lead flashings, chimney stacks and valleys and parapet gutters.
Water getting into a London home frequently comes from a detail you cannot 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 Dancers Hill, 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.
You can share the report with anyone who needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent, whichever applies.

What we need to know
A little information up front helps. It is useful to include:
- Why you want a survey: buying, a leak, a storm or new work
- Whether there is a loft hatch, a shared roof or tricky access
- The address and postcode of the property
- The type of building and roof, such as pitched or flat
To book a survey, ring 07833 053749 or use the contact form and tell us the address and what’s prompted the survey. We’ll confirm the price before booking.
Checking the roof from the ground
If you have a loft with safe access, take a look inside. Take a torch and only step on boards or joists, and look for staining, damp timber or daylight coming through.
The one thing to avoid is getting up close. Slates, tiles, flat roofs and rooflights can give way. That part is for a survey.
Surveys for landlords and agents in Dancers Hill
For blocks of flats, a roof survey helps managing agents and residents’ management companies plan ahead. Recommendations are set out in order of urgency where relevant, which helps with budgets and planning.
If you own several properties, you can book surveys for several addresses. To discuss a number of properties, call 07833 053749 or send us an email with the addresses.
Roof by roof
Lead flashings
A leak at a flashing often shows some way from the joint. We check every flashing that could feed the stain.
Chimney stacks
Our chimney check is a visual inspection of the stack, and it isn’t a flue or gas safety check.
Common questions in Dancers Hill
Will parking be an issue for a roof survey in Dancers Hill?
Usually it’s manageable with a little notice. Tell us what parking is available nearby, and the visit is planned around it.
Is my home in Dancers Hill listed or in a conservation area?
We cannot confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case.
How long will you be at the property?
It typically takes about one to two hours, more where the leak is intermittent or the roof is large. Report times depend on the package.
Is there anything I need to do ahead of the visit?
Keep a note of when it leaks. Clear access to the loft. If water is near any fittings, have an electrician check them.
What happens next?
The report arrives by email. The Standard Survey includes a follow-up consultation, and the Premium Survey an in-person consultation, so you can talk the findings through.
Can you survey at the weekend?
We survey seven days a week: weekdays, Saturdays and Sundays. Tell us which days suit you when you book.
Can you survey a shared roof?
Yes, once access has been agreed. Roofs over flats are often shared, so we need permission from the building owner or managing agent. We can only inspect what we’re given access to.
What we do, step by step
You do not need to do much on the day. Show us any stains, drips or problem areas you know about, and we will get on with the inspection. The survey itself takes roughly 1–2 hours, more where the leak is intermittent or the roof is large. For a visit in Dancers Hill, parking and access are the things to plan: let us know about permits, visitor bays or off-street space, which floor the property is on and how to get into the loft. On the day, the roof is looked at from the ground, from windows, from inside the loft space and from the roof where it’s safe.
- We start with what you’ve seen: where the stain is and when it gets worse.
- We look at the stain, the ceiling and the loft above it.
- We check the likely entry points outside, like flashings, valleys, chimneys and gutters.
- Where it helps, we take moisture readings and use thermal imaging.
- Your report sets out where the water is most likely getting in, with photos and recommendations.
Before the survey
- Show us where any leaks or stains appear
- Mention any parking restrictions on your street
- Keep pets in another room

Roof leak investigations in Dancers Hill: local notes
Outer London has plenty of Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, frequently with hipped roofs in clay or concrete tiles. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. Each of these roof types has its own typical places for water to get in. Historic houses such as Wyllyotts Manor, about 1.5 miles north-east, show how far back building in the area around Dancers Hill goes. Older homes in the wider area often have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years, and the council can say whether a home is in a conservation area.
Parking in Dancers Hill, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day easier. Landlords with a home close to Potters Bar station may find that a tenant living with a leak needs the cause found, not just the stain painted over. Shop and office owners around Spires Shopping Centre may find that a leak can close part of a shop or office, so finding the cause quickly matters.
