Flat roof survey in Lissenden Gardens, Greater London
Surveys of flat roofs on homes, extensions and commercial buildings for Lissenden Gardens, from an experienced roof surveyor. Every survey comes with a written report and photographs.
- Splits, cracks and crazing
- Signs of deflection in the roof deck
- Water getting in at rooflights
Useful tips for Lissenden Gardens property owners
A few practical points come up again and again on our surveys. They apply to most roofs:
- Ask whoever fits equipment on the roof to make good the covering
- Look for standing water a day after rain
- Note any new marks on ceilings beneath the roof
- Keep outlets clear of leaves and moss
If you are buying, the report gives you something specific to take back to the seller or agent. It can support a request for work before completion or a conversation about price, depending on what we found.
Have the roof surveyed every few years, and after any work that goes through it. That catches changes early and builds up a record of the roof.
About our flat roof survey in Lissenden Gardens
Offices, shops, industrial units and blocks of flats often sit under large flat roofs. A survey of a roof this size picks out worn covering, standing water and outlets that need attention. The photographed record helps you plan and budget for work. We quote commercial roofs on their size and how they’re reached, so it helps if you phone 07833 053749 or email us with the address and a rough idea of the roof area. We survey upstands and outlets, EPDM rubber and single-ply membranes, and common reasons people get in touch are outlets choked with leaves and silt and raised blisters across the surface.
Across London, flat roofs are everywhere, from back additions and dormers to roof terraces, blocks of flats and offices. They’re covered in felt, asphalt, EPDM rubber, GRP fibreglass or single-ply membranes, each with its own weak points. In Lissenden Gardens, as anywhere in London, the right approach depends on what the roof is made of. Many older flat roofs are felt or asphalt, and many newer ones EPDM rubber or GRP.
With the Standard Survey, you also get moisture detection, a structural check and a follow-up consultation. The Premium Survey goes further, with thermal imaging, drone inspection where applicable, structural analysis and an in-person consultation.

Flat roof surveys around Lissenden Gardens
Many homes in inner London are Victorian and Edwardian terraces, often with 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. If your home in Lissenden Gardens is one of them, lead flashings, party-wall upstands and shared chimney stacks are part of the picture too. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. Keats House, about 0.8 miles west, is one of the historic houses in the wider area around Lissenden Gardens. If your home is one of the older ones, expect a mix of original materials and later repairs on the roof.
Shop and office owners around O2 Centre may find that outlets and upstands on commercial flat roofs are the places to check before trouble starts. For a London address like Lissenden Gardens, it is useful to know about controlled parking before the day.

Questions from Lissenden Gardens
How do I find out if my home in Lissenden Gardens is listed?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Is parking a problem for a survey in Lissenden Gardens?
It depends on the street. Where there are permit zones, a visitor permit or nearby pay-and-display bay works well.
Is Lissenden Gardens in your area?
Yes. We survey roofs in Lissenden Gardens and the rest of Greater London, as part of our work across London and the South East. To book, phone 07833 053749 or use the contact form.
Does the weather affect the survey?
It can, depending on the survey. Drones can’t fly safely in strong wind or a downpour, and thermal imaging works best with a dry roof, little wind and a sunny day beforehand. If the conditions are not right, we will talk to you about another date.
Do I need to be at home?
Someone needs to let us in if we are looking inside or in the loft. Access is agreed with you when booking.
How much is a survey?
Our price is from £150, including VAT. Our three packages are Basic from £150, Standard from £250 and Premium from £400, including VAT.
Do you use drones?
Yes, where it’s applicable. Whether we can fly on the day depends on the weather and the airspace rules, including flight restriction zones near airports. We are a CAA-registered drone operator.
How the survey changes by roof type
Mastic asphalt
Older asphalt can become brittle and crack as the roof moves. The report shows where it’s cracking and how far it seems to extend.
EPDM rubber
Lifting at the edges and loose areas of membrane are common EPDM problems. We record any we can see, with photos.
What we are asked to look at in Lissenden Gardens
Ponding keeps the covering wet and wears it faster. It typically comes from poor falls, a blocked outlet or a deck that has dipped. Leaves and silt from nearby trees can soon choke an outlet.
Signs worth acting on include:
- Leaks around rooflights
- Splits and cracks in the covering
- Standing water left after rain
- Signs of deflection in the roof deck
If you own one of the older houses in the streets near Highgate Road Chapel, the joins between later flat roofs and the old walls are where problems typically start.
What to check before booking
- Whether the loft space is looked at, where there is one
- Whether you get a written report with photos
- What’s outside the scope of the survey
- Which viewpoints they use to see the roof
How the survey works
The visit usually starts outside and finishes in the loft: outside views come first, then the loft space if there is safe access. All told, expect about 1–2 hours for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. In Lissenden Gardens, as in much of London, lots of properties are flats or terraces without side access, so rear slopes are viewed from windows, the loft or, where a flight is allowed, by drone. Mention any building rules, key holders or managing agents as you book.
- You send us the address and, for commercial roofs, an idea of the roof’s size.
- We check the rooms or spaces under the roof for staining where there’s access.
- We view the roof from safe positions and never walk on fragile surfaces.
- We record every defect with a photo and its likely cause.
- You get a report setting out the condition and our recommendations, in order of urgency.
Before the survey
- Note where any stains or damp appear
- Find any records of previous roof work
- For flats, check roof access has been agreed
Getting a price
A quick phone call is usually the easiest start: ring 07833 053749 or drop us an email. The price is agreed before a date is set.

Should I look at the roof myself first?
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it, as it helps a surveyor trace the cause.
What you can’t do safely is get up close. Slates, tiles, flat roofs and rooflights can give way, and a fall can be serious. That is where a survey comes in.
