How a flat roof survey works in Barnes Cray
Standing water is one of the first things we look for on a flat roof. It can point to poor falls, a blocked outlet or a deck that is deflecting. The survey notes any ponding, the state of each outlet and any dips that hint at a sagging deck. If the deck itself looks like a structural concern, we’ll recommend a structural engineer. If you are worried about water getting in at rooflights and dips that suggest the deck is deflecting, a survey will tell you what’s going on.
Flat roofs in smaller places like Barnes Cray can be more exposed, especially where nothing shelters them, where wind can catch loose edges and trims. Sun on a flat roof also ages felt and bitumen. Splits, blisters and lifting edges are what to look out for. Standing water that lingers for days after rain is another sign worth watching for.
Most points in the report come with a picture, because a photo of a cracked flashing says more than a paragraph. If something couldn’t be seen safely, the report is clear about it.

What a flat roof survey looks like in Barnes Cray
The wider area around Barnes Cray has a long history of building, with Hall Place and Gardens about 1.7 miles south-west. 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. Handmade clay tiles, including Kent peg tiles hung on pegs through two holes, are typical of older Kent buildings. Kent’s older buildings take in oast houses and timber-framed Wealden hall houses as well. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
If you let a flat or house near Slade Green station, flat roofs on let property tend to be checked only when they fail, which is the costly way round. For site and facilities teams at buildings like Haberdashers' Aske's Crayford Academy, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. For businesses in and around places such as Broadway Shopping Centre, a flat roof over a business is out of sight and out of mind until it leaks.

Questions from Barnes Cray
Does a conservation area affect roof work in Barnes Cray?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it is in a conservation area. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Will you come out to Barnes Cray?
Yes, smaller places are covered as well as towns. We cover the whole of London and South East England. Just mention lanes, gates or anything else about the route when you book.
How long have you been surveying roofs?
More than 5,000 surveys over 20+ years.
Which flat roof coverings do you cover?
Felt, asphalt, EPDM, GRP and single-ply roofs are all covered. Not sure what yours is? We’ll tell you in the report.
How much is a survey?
Prices start from £150, including VAT. What you pay for your roof depends on its size, height, access and the package, and it is agreed before booking.
Will I get photos?
Yes. Photos are part of every report.
Will you check the loft?
Typically, if there is one and it can be reached safely. From inside, the underside of the roof often shows damp, staining or daylight that cannot be seen from outside.

How the survey works
We work from the outside in: first the slopes, edges and gutters from every safe viewpoint, then the loft space where it can be reached. All told, expect between one and two hours on an ordinary house, while a commercial roof takes nearer three to four hours. Some parts of a survey depend on the weather, so a visit to Barnes Cray is booked with the forecast in mind: drone flights and thermal imaging need the right conditions, while a look from ground level and the loft can go ahead in most weather.
- You send us the address and, for commercial roofs, an idea of the roof’s size.
- Inside, we look for signs of water under the roof where we can reach.
- The roof is inspected from every safe viewpoint, without walking 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
- If you are buying, let the agent know when we are coming
- Dig out any old roof reports or invoices
- Check the loft hatch can be reached
Booking a survey
We survey roofs seven days a week. To arrange a day that suits you, phone 07833 053749 or use the contact form.
Advice
What this survey can’t tell you
Without opening up the roof, some things stay hidden, so a survey has limits:
- The condition of the deck or insulation hidden under the covering
- Testing older roof sheets for asbestos
- An exact number of years the roof has left
If you are not sure which survey you need, phone 07833 053749 or email us and we will give you a straight answer. What a survey covers and does not.
What this survey covers
- Mastic asphalt
- Upstands and outlets
- Single-ply membranes
- Felt flat roofs
- EPDM rubber
- GRP fibreglass
Different roofs, different checks
Felt and built-up roofs
The edges and upstands of a felt roof are usually where trouble starts. Every upstand and edge is checked, with photos of any that have lifted or cracked.
Single-ply membranes
Single-ply PVC and TPO membranes are common on commercial roofs and newer buildings. The survey looks at welded seams, edges, fixings and signs of damage.
What you can safely check yourself
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, and those are details a survey looks at closely.
What you can’t do safely is get up close. Roofs are fragile and slippery, and a fall can be serious. That is where a survey comes in.
Useful tips for Barnes Cray property owners
From years of surveys, a few habits stand out as worth the effort:
- Watch the ceilings below the flat roof for stains
- Look for standing water a day after rain
- Plan a survey before the covering reaches the end of its usual life
- Keep records of when the roof was laid and what work has been done
Once we have been, the findings are written up with photos. It explains the covering, its condition and every defect, and what we recommend. Turnaround is within 48 hours for a Basic Survey, 24 to 48 hours for a Standard Survey and the same day for a Premium 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 to keep well clear of rooflights and fragile sheeting.
