About our flat roof survey in Single Street
Many commercial buildings and blocks of flats have big flat roofs. On a roof like this, a survey shows where the covering is wearing, where water is ponding and which outlets 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 call 07833 053749 or send us an email with the address and a rough idea of the roof area. We are often asked to look into raised blisters across the surface and loose or cracked edge trims, across upstands and outlets, felt flat roofs and EPDM rubber.
On a London roof terrace or a flat roof over a back addition, water frequently 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 Single Street, the roof above may belong to the building rather than one flat.
Findings are set out part by part, from the coverings down to the gutters, with a note and a photo for each point. You will see the good as well as the bad.

Questions from Single Street
Is parking a problem for a survey in Single Street?
London parking needs a little planning, so let us know about permits, bays or a driveway as you book. The visit is then planned around what’s available.
Is my home in Single Street listed or in a conservation area?
Your council is the best source, with Historic England’s list for listed buildings. Both listing and conservation areas can limit changes of roofing material.
Is Single Street in your area?
Yes. We cover Single Street and the rest of Greater London, as part of our work across London and the South East. To book, phone 07833 053749 or send us an email.
What happens after the survey?
We email you the written report with photos and recommendations. You can use it to talk to a seller, an insurer, a roofer or a managing agent, whichever applies.
Do you look for flat roof leaks?
Our survey looks across the whole roof, not only above the stain. Splits, open laps, upstands, outlets and rooflights are all checked. If the cause cannot be seen, we will say so and suggest what would help.
Does the weather affect the survey?
Some surveys depend on the weather more than others. Drones cannot fly safely in strong wind or heavy rain, and thermal imaging works best after a sunny day, with a dry roof and little wind. We’ll rearrange with you if the weather isn’t right.
Can you tell me how long my flat roof will last?
There’s no honest way to give an exact number of years. As a guide, felt often lasts around 15 to 20 years, EPDM frequently 30 to 50 and GRP up to about 30, but your report describes the actual condition.
What a flat roof survey doesn’t cover
No survey can tell you everything, and we’d rather be clear about that before you book. Bear these in mind:
- Hidden layers beneath the covering
- Areas we can’t see or reach safely, including fragile rooflights and sheeting
- A promise that the roof won’t leak in future

Useful tips for Single Street property owners
Nothing here needs a ladder. A few suggestions:
- Check from a window for ponding after heavy rain
- File the paperwork for the roof and any repairs
- Check that new brackets or units haven’t damaged the covering
- Check ceilings under the roof for damp patches
Buyers can take the findings back to the seller or the agent. It can support a request for work before completion or a conversation about price, depending on the findings.
Book a survey every few years, and again after new fixings, units or rooflights go in. You will spot changes early and have a record to look back on.
What happens on the day
We look at the roof from outside and, where it is relevant and there is safe access, from inside the roof space too. Inside, we look for staining, damp, gaps and signs of movement, as far as the space allows. All in, the survey normally takes about one to two hours at a typical home, while a commercial roof takes nearer three to four hours. Many London properties are flats or terraces with no 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 when 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.
Getting ready for the survey
- Keep pets out of the way during the survey
- Buyers: confirm access with the estate agent or seller
- For a flat or shared roof, check access with the building owner or managing agent

Common roof problems in Single Street
Water that does not drain sits on the roof and speeds up wear. It usually 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:
- Water getting in at rooflights
- Damaged trims at the roof edge
- Outlets choked with leaves and silt
- Blistering in felt or asphalt
If you own a rental within reach of Chelsfield station, a flat roof over a rented flat is easy to forget until the tenant reports a leak.
Questions to ask before you book
- Whether you get a written report with photos
- Is there a chance to talk the report through?
- How soon the report will arrive
- Whether the inside of the roof is included
Flat roof surveys around Single Street
About 1 mile north-west lies Down House, a reminder of how long the area around Single Street has been built on. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and any change of roofing material on a listed home needs checking with the council first. Outer London has plenty of Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, often with hipped roofs in clay or concrete tiles. If your home in Single Street is one of them, bay roofs, hips and later dormers each have their own details. Mixed in with those pitched roofs are plenty of flat ones, over rear extensions, dormers, garages and shops.
Take a building like Cudham Church of England 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 Church of St Peter and St Paul: flat-roofed rear additions and dormers added over the years are worth checking.

GRP fibreglass
GRP roofs are laid as a resin and glass-fibre layer over boards. We look for cracks at board joints, around trims and at upstands.
Mastic asphalt
With age, asphalt can harden and crack with movement. The report shows where it is cracking and how far it seems to extend.
