Flat roof survey in Lessness Heath: what you get
A flat roof doesn’t shed water the way a pitched roof does. Water lies on the surface for longer, so a small split or a blocked outlet can soon lead to a leak. The surface, the falls, the upstands and the trims are all looked at closely, and we note any sign that the deck below has got wet. The aim is to find problems before they show up as a stain on a ceiling. If you are worried about a sagging deck under the covering and outlets choked with leaves and silt, a survey will tell you what’s going on, whatever the roof.
On a London roof terrace or a flat roof over a back addition, water often runs under the covering before it shows. Outlets, upstands against parapet walls and joins with the main roof are frequent culprits. In a converted house in Lessness Heath, the roof above may belong to the building rather than one flat.
You receive the findings by email, easy to pass on to a roofer, an agent or an insurer. Turnaround is within 48 hours for Basic, 24–48 hours for Standard and same day for Premium.

DIY checks: what’s safe
What you can’t do safely is get up close. Slates, tiles, flat roofs and rooflights can give way, and falls from height are serious. That’s where a survey comes in.
Watch the gutters in a downpour, from a window or the ground. Overflowing water can be a sign of a blockage or a gutter that has dropped.
Practical tips
You don’t need to be a roofer to help. What helps most:
- Never stand on rooflights or fragile sheeting
- Book a survey every few years
- Check that new brackets or units haven’t damaged the covering
- Note the date and type of any roof work
Landlords, owners and managing agents can keep the report as a dated record of the roof. It helps when planning maintenance budgets, and it makes changes easy to spot at the next survey.
Keep foot traffic on a flat roof to a minimum. Where someone does need access, ask them to use boards or a protected route, and remind them never to step on rooflights or fragile sheets.
How we price flat roof surveys
Survey packages start from £150, inc. VAT. The price for your roof depends on:
- How many separate roofs there are, such as extensions, dormers and garages
- Commercial roofs and larger buildings
- The roof’s overall size
- How complicated the roof is, with its valleys, chimneys and parapets
Price depends partly on the package: Basic from £150, Standard from £250 or Premium from £400, all inc. VAT. The roof’s size, height and access matter as well.
Getting in touch
What helps most when you contact us:
- The kind of building and roof involved
- The property’s address and postcode
- What’s prompted the survey
- Pictures of the roof from a safe spot, if you have them
When you are ready to go ahead, ring 07833 053749 or drop us an email. We will suggest a package, agree the price and find a date, weekday or weekend.
FAQs for Lessness Heath
Does a conservation area affect roof work in Lessness Heath?
We cannot confirm that for you, but Historic England’s list and your council can. Both listing and conservation areas can limit changes of roofing material, and councils can also use Article 4 directions.
Do you carry out roof surveys in Lessness Heath?
We do. The survey and report are the same in Lessness Heath as anywhere else, and visits run on weekdays and weekends.
How soon will I get the report?
The Premium Survey report comes the same day, the Standard within 24–48 hours and the Basic within 48 hours. Each one is emailed.
Is a flat roof survey the same as a building survey?
No. It’s a closer look at the flat roof, not a survey of the whole property. It complements a RICS home survey rather than replacing it, and structural calculations need a structural engineer.
Will I get photos?
Yes. We photograph the roof as we go, and they go into the written report alongside our recommendations.
Do you cover flat roofs on blocks of flats?
Yes. We survey flat roofs on commercial buildings as well as homes. Expect about 3 to 4 hours on site for most commercial roofs, and larger roofs are quoted for their size.
What does ponding on a flat roof mean?
Ponding is worth looking into. It often means a blocked outlet, poor falls or a dipping deck, and it wears the covering faster. Our survey notes the ponding and what seems to be causing it.
What happens if roof problems are left?
Flat roofs can’t typically be seen from the street, so they’re frequently overlooked. Owners often learn the roof is at the end of its life only when it leaks. Regular surveys mean it won’t come as a surprise. 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.
Prices start from £150, inc. VAT, for a Basic Survey. The Standard Survey starts from £250 and the Premium Survey from £400. We confirm the price for your survey before booking.

Flat roof surveys in Lessness Heath: local notes
Further from the centre, London’s housing takes in interwar semis with hipped roofs in clay or concrete tiles as well as slate-roofed terraces. If your home in Lessness Heath is one of them, bay roofs, hips and later dormers each have their own details. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. With Red House about 2.3 miles south-west, Lessness Heath sits in an area with a long building history. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs.
If you let a flat or house near Belvedere station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies. If you look after a building like Lessness Heath Primary School, schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks. Take an older house close to Parish Church of All Saints: the joins between later flat roofs and the old walls are where problems normally start.

How it works
Every visit follows the same pattern: we hear what you’ve seen, look at the roof from every safe viewpoint, photograph what we find and make notes for the report. It normally takes about one to two hours for a house, though large, tall or awkward roofs take more time. In a London conversion, the way into the roof space is often from a communal landing or the top flat. Where that is the case, access needs agreeing with whoever controls that landing. Everything else is planned around the building, not the postcode.
- We agree the roof to be surveyed, its use and any leaks you know about.
- We look at the roof from the ground, windows and the roof where it is safe.
- We check the covering for splits, blisters, ponding and wear.
- We photograph and record the outlets, upstands, trims and rooflights.
- The report, with photographs and recommendations, comes to you by email.
