FAQs for Heron Quays
How do I find out if my home in Heron Quays is listed?
For listing, use Historic England’s list; for conservation areas, ask the council. The answer matters most when a change of material is on the cards.
Is Heron Quays in the area you cover?
Yes, Heron Quays is one of the places we work. The survey and report are the same in Heron Quays as anywhere else.
Will you definitely find the leak?
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.
How many surveys have you done?
More than 5,000 surveys over 20+ years.
What happens after the survey?
The report comes by email, and you decide the next step: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
Does this replace a RICS home survey?
No. We check the roof, not the whole building, so it is not a RICS Level 2 or Level 3 survey. It can sit alongside a RICS survey if you want both.
Is thermal imaging part of a leak investigation?
Thermal imaging is used where it’s useful, and it is included in our Premium Survey. It shows temperature differences, not water itself, so we confirm its findings with moisture readings.
About our roof leak investigation in Heron Quays
Roof leaks rarely show up where you’d expect. Water frequently travels along timbers or underlay before it finds a way down, so the stain on your ceiling is seldom right under the hole. Our leak investigation traces it back. A repair aimed only at the stain can miss the cause entirely. Tracing the route first means any work can be aimed at the right place. We’re frequently asked to look into water coming in around a roof light or dormer and wet patches high on an inside wall, on flat roof details, lead flashings and slate and tile slopes.
In London, leaks often start somewhere hidden: a butterfly roof’s central valley gutter, a parapet gutter, a chimney flashing or a flat roof over a back addition. For a leak or storm damage in Heron Quays, 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.
Most points in the report come with a picture, because a photo of a cracked flashing says more than a paragraph. Anything out of sight on the day is listed as such.

How the survey changes by roof type
Valleys
Stains from a valley leak often show some distance off. We trace the route from the loft where there’s safe access.
Slate and tile slopes
Cracked mortar lets ridge and hip tiles move. Water then gets in along the top of the roof.
How it works
Once we’ve finished looking, we write up our findings as a written report with photos, sent to you by email. On timing, it normally takes roughly 1–2 hours, more where the leak is intermittent or the roof is large. In Heron Quays, visits are available on weekdays and at weekends. It helps if you can point us to a visitor permit or a nearby bay, and to clear a path to the loft hatch. A back bedroom window can be the best vantage point for a rear addition, so we may ask to use one.
- You pick a Basic, Standard or Premium Survey.
- A visit is booked for a weekday, Saturday or Sunday.
- The investigation works from the stain back to the roof.
- Where it is useful and included, we take moisture readings and use thermal imaging.
- The report explains the likely entry point and what needs attention.
Before we arrive
- Mention any parking restrictions on your street

Leave it or get it looked at?
If a leak has been ‘fixed’ before and has come back, the cause was probably missed. A careful investigation looks at every likely route, not just the obvious one. It gives the next repair a far better chance. London’s older roofs often have bitumen felt underlay or none at all, so a slipped slate can soon mean water inside. Left unchecked, water soaks into timber and plaster and the damage spreads.
Our price is from £150, including VAT. Basic starts from £150, Standard from £250 and Premium from £400, VAT included, and we can help you choose.

How we price roof leak investigations
Prices vary from roof to roof, and it comes down to:
- Whether thermal imaging or a drone is needed
- House, block, shop or office
- The roof’s overall size
- How complicated the roof is, with its valleys, chimneys and parapets
Roof leak investigation starts from £150, including VAT. The final price depends on how big and how high the roof is, access and the package you choose.
What we need to know
What helps most when you contact us:
- The reason for the survey, such as buying, a leak or storm damage
- Pictures from the garden or a window, if you have them

- Any deadline, such as an exchange date
We survey roofs seven days a week. To find a date that works for you, ring 07833 053749 or drop us an email.
What we can’t see

- Whether rotten timbers meet design loads
- Carrying out the fix
- An intermittent leak that shows no trace on the day

What a roof leak investigation looks like in Heron Quays
Many homes in inner London are Victorian and Edwardian terraces, often with Welsh slate roofs. Many have butterfly roofs draining to a central valley gutter, with parapet walls and gutters hidden behind them. In a house like that, shared stacks, party-wall upstands and lead flashings all need looking at as far as they can be seen. Knowing the roof type helps narrow down where water may be getting in. With Queen's House about 1.7 miles south-east, Heron Quays sits in an area with a long building history. 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.
Anyone responsible for a site like Seven Mills Primary School will know that on a building that size, finding the source of a drip means looking well beyond the stain. Living close to Sir John McDougall Gardens is pleasant, but mature trees mean leaves in gutters and valleys each autumn, and blocked gutters overflow and soak walls. If you look after a shop, office or commercial unit, for instance near Surrey Quays Shopping Centre, a leak can close part of a shop or office, so finding the cause quickly matters.

Checking the roof from the ground
After strong wind, take a look from the pavement or garden: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Leave anything above ground level to a survey.
Inside, the loft is a good place to look, with care. Use a torch and stay on the joists or boards, checking for stains, damp wood or chinks of daylight.
