Roof leak investigations for homes and businesses in Lissenden Gardens
The aim is to find where the water is getting in and explain it. You get a written report with photos showing the likely entry point and the route the water is taking, plus recommendations on what needs attention. It gives any roofer a clear brief. The investigation finds and explains the cause, while the repair is a separate matter. If you’ve noticed stains around a skylight and damp on a chimney breast, a survey will tell you what’s going on, on valleys and parapet gutters, chimney stacks and rooflights and dormers alike.
Water getting into a London home often comes from a detail you can’t see from the street: a butterfly roof’s central valley gutter, a parapet gutter, a chimney flashing or a flat roof over a back addition. Whether you are tracing a leak or recording storm damage in Lissenden Gardens, those are among the first places to look. Water from a hidden gutter can run along joists and show up a room or two away.
The report is yours to share with whoever needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent, whichever applies.

How we price roof leak investigations
Every roof is different, so prices are confirmed before you book. These are the things that affect it:
- House, block, shop or office
- Extensions, dormers and garages with roofs of their own
- The roof’s overall size
- If the survey needs thermal imaging or a drone
For a price for your roof in Lissenden Gardens, call 07833 053749 or send us an email and let us know about the roof. We’ll confirm the figure before booking.
What to tell us when you contact us
These details help when you get in touch:
- How the loft is reached, if there is one
- Dates you’re working to, like exchange
- Any marks or damp showing indoors
- Where the property is, with the postcode
Our phone lines are open seven days a week. For a price or to book, ring 07833 053749 or drop us an email.
What we look for on each type of roof
Slate and tile slopes
Ridge and hip tiles can loosen as their mortar cracks. Rain can then run in at the ridge.
Flat roof upstands and outlets
On a flat roof, a leak can show some distance from the split. Where conditions allow, moisture readings and thermal imaging help narrow it down.
Checking the roof from ground level
Your own check is a good start, but it is not a survey. You won’t see flashings, valleys or the backs of chimneys properly from the ground.
A lot can be seen from ground level. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Please don’t climb up for a closer look.

Lissenden Gardens questions
Do you cover Lissenden Gardens?
Yes, Lissenden Gardens is within the area we cover. We cover the whole of London and South East England. Just ring 07833 053749 or use the contact form and let us know about the property, and we’ll talk through which survey suits.
Can parking be tricky for a visit in Lissenden Gardens?
Parking in Lissenden Gardens, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
How fast do I get the report?
That depends on the survey you book: the Basic Survey report arrives within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey the same day. Reports are sent by email.
Do I have to be there for the survey?
It depends on what we need to see. Inside the building and in the loft, we need someone to let us in.
Can you survey a shared roof?
Yes, once whoever controls the roof agrees access. On a shared roof we can only inspect the parts we’re allowed to reach, and the report makes that clear.
Is it the same as a RICS Level 2 or Level 3 survey?
No. This is a survey of the roof only, so it is not a RICS Level 2 or Level 3 survey. Many buyers have both.
Can you always find the source?
We cannot promise to find every leak on one visit. Many leave clear signs, but some only appear in certain weather. The report sets out what we found and the most likely routes.
Tips from our surveys
From years of surveys, a few habits stand out:
- Clear the loft hatch so we can get in
- Let us know what has already been tried
- Leave roof access to professionals
- Catch drips in a bucket and protect the floor
Keep the report after the work is done. If water appears again, it shows what was found before.
Plan a roof survey every few years. Flashings, valleys and flat roof details are frequent weak points, and catching wear early keeps water out.
Honest limits
No survey can tell you everything, and it’s better to know them up front. Keep these in mind:
- Putting the leak right
- A structural engineer’s report
- Defects hidden under coverings or inside walls without opening up
If you are not sure which survey you need, call 07833 053749 or email us and we’ll give you a straight answer. What our survey covers.

Leaks and storm damage in Lissenden Gardens
The wider area around Lissenden Gardens has a long history of building, with Keats House about 0.8 miles west. If your house is among the older ones, expect a mix of original materials and later repairs on the roof, and a listed home or one in a conservation area may need consent for changes of material. Inner London’s Victorian and Edwardian terraces often have Welsh slate roofs. From the street you may see only a parapet, with a butterfly roof and a valley gutter behind it draining to the back. Shared chimney stacks, party-wall upstands and lead work come with this kind of house. The covering and its details give the first clues when tracing where water is coming from.
Anyone responsible for a site like Parliament Hill School will know that water through a big roof can travel a long way before it drips, so the search covers more than the obvious spot. 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. For landlords with property near Gospel Oak station, a clear finding on where water gets in helps you brief a roofer right away.

How it works
On the day, we start by asking what you’ve noticed and what you’d like to know. We then inspect everything that can safely be seen, using the ground, windows, the loft and a drone where applicable. The survey normally takes about 1–2 hours on an ordinary house, rising to roughly 3–4 hours on a commercial building. In Lissenden Gardens, visits are available on weekdays and at weekends. London parking is frequently by permit or pay-and-display, so it helps to know what’s near you, and to clear a path to the loft hatch. Upstairs rooms at the back are useful too, as they often give the best view of a rear addition.
- We help you choose the package that suits the leak.
- We agree a date, including weekends.
- The investigation works from the stain back to the roof.
- Where it is useful and included, we take moisture readings and use thermal imaging.
- You get photos, the likely cause and clear recommendations.
