About our roof leak investigation in Greenhill
Leaks tend to begin where one part of a roof meets another. Flashings at chimneys and walls, valleys, gutters, parapets and flat roof upstands and outlets are the usual suspects. Each of these is checked in turn and we follow where the evidence leads. Every chimney, dormer and roof light adds more joints to check. We look at all of them, from each safe vantage point. We are often asked to look into water through the ceiling under a flat roof and water dripping from rafters or underlay, across rooflights and dormers, lead flashings and slate and tile slopes.
In a London flat, water can travel some way before it shows. That makes the source hard to pin down, and finding it matters for whoever has to deal with it. In Greenhill, we inspect what we can reach safely and are given access to. Tell us when the water shows, and in what kind of weather.
Pictures do a lot of the work in our reports, because a photo of a cracked flashing says more than a paragraph. If something couldn’t be seen safely, the report is clear about it.

How the survey changes by roof type
Slate and tile slopes
On slate roofs, corroded nails let slates slip. One slipped slate can be enough to cause a leak, particularly in driving rain.
Flat roof upstands and outlets
Upstands seal the edge of a flat roof where it meets a wall. A low or cracked upstand is a common way in.
What a roof leak investigation looks like in Greenhill
Close to the centre of London, a great many houses are Victorian or Edwardian terraces, many of them roofed in Welsh slate. From the street you may see only a parapet, with a butterfly roof and a valley gutter behind it draining to the back. If your home in Greenhill is one of them, lead flashings, party-wall upstands and shared chimney stacks are part of the picture too. Knowing the roof type helps narrow down where water may be getting in. 2 Willow Road, about 0.3 miles north-east, is one of the historic houses in the wider area around Greenhill. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and a listed home or one in a conservation area may need consent for changes of material.
Anyone responsible for a site like The Royal School will know that tracing a leak on a big roof starts with where the water appears and works back. For businesses in and around places such as O2 Centre, a leak can close part of a shop or office, so finding the cause quickly matters. If you live in an older home near Rosslyn Hill Unitarian Chapel, old mortar, worn lead and slipped slates are the usual suspects when water gets in.
Greenhill is about 1 mile north-east of Hampstead, in Greater London. We survey roofs in Greenhill as part of our work across London and the South East. Greenhill is one of the places in Greater London we cover for roof leak investigations.
Roof leak investigations in NW3 and NW6 work the same way as everywhere else we cover. Local streets include Back Lane, Well Road and Ornan Road, and we cover them all. Close by, we survey roofs in Hampstead (1 mile south-west), Vale of Health (1 mile north), West Hampstead (1 mile west), Fortune Green (1 mile west) and Haverstock (1 mile south-east).

Local landmarks in Greenhill
Typical jobs here are in homes near Cecil Sharp House, Fitzjohn's Primary School and King William IV Public House and the streets around them. You’ll also find South Hampstead High School (0.6 miles south) and Hampstead Heath (0.7 miles north-east). Greenhill has its own railway station: Hampstead Heath station. Well-known places in the area include New End Hospital (less than half a mile north-west) and Montfichet's Tower (4.3 miles south-east). For a walk, there’s Belsize Wood and Parliament Hill.
DIY checks: what’s safe
The one thing to avoid is getting up close. Roofs are fragile and slippery, and a fall can be serious. That part is for a survey, using safe viewpoints and a drone where applicable.
Inside, the loft is a good place to look, with care. Take a torch and only step on boards or joists, and look for staining, damp timber or daylight coming through.
Honest limits
Our survey isn’t a RICS Level 2 or Level 3 survey, a structural engineer’s report or an asbestos survey. It also has these limits:
- Leaks from plumbing, tanks or pipework rather than the roof
- The repair itself (the investigation finds and reports the cause)
- Faults hidden behind ceilings or boarding

What happens on the day
After the inspection, everything we found is written up as a written report with photos. As for time on site, it typically takes about 1–2 hours for most houses; commercial roofs usually need 3–4 hours. In converted houses and mansion blocks, the loft hatch is frequently on a shared landing. Where that is the case, access needs agreeing with whoever controls that landing. Otherwise, the visit in Greenhill runs like any other.
- You let us know where the water appears, when, and what the weather was doing.
- Inside, we check the stain and the ceiling around it.
- In the loft, we follow any signs of water back towards the roof.
- We inspect the likely entry points outside, from the ground, windows and the roof where safe.
- You receive a report with the likely source, photos and recommendations.
Getting ready for the survey
- Point out any leaks or damp patches
- Clear the way to the loft hatch
- Have any questions written down, so nothing gets missed

Your questions about roof leak investigations in Greenhill
Is my home in Greenhill 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.
Do you carry out roof surveys in Greenhill?
Yes, Greenhill is one of the places we work. The survey and report are the same in Greenhill as anywhere else, and visits run on weekdays and weekends.
When does the report arrive?
The Premium Survey report comes the same day, the Standard within 24–48 hours and the Basic within 48 hours. Each one is emailed, ready to forward.
How do I arrange a roof leak investigation in Greenhill?
The quickest way is to ring 07833 053749 or email us. Give us the address and a few details about the roof, and we’ll take it from there. We survey seven days a week.
Can every leak be traced?
We can’t promise it. Water can travel a long way, and some leaks only show in particular storms. Where the source isn’t certain, we list the likely routes in order.
Do you test for asbestos?
No. We don’t sample or test for asbestos. The report may flag materials that could contain asbestos on buildings built or refurbished before 2000, with a recommendation to have a specialist asbestos surveyor check before it is disturbed.
Does the report include photos?
Yes. We photograph the roof as we go, and the report uses them to show each finding alongside our recommendations.
Useful tips for Greenhill property owners
Some practical points come up on survey after survey. They apply to most roofs:
- Take dated photos of the leak
- Mention any plumbing above the damp area
- Catch drips in a bucket and protect the floor
- Don’t touch fittings that water is reaching
We email the report to you, with photos of what we found. It explains the likely entry point, the route the water takes and our recommendations. Basic reports come within 48 hours, Standard within 24 to 48 hours and Premium the same day.
Look at the roof from the ground after strong winds. Slipped slates, lifted ridge tiles and debris on the ground are signs to act on. Small faults dealt with quickly rarely become leaks.
