How a flat roof survey works in Long Ditton
Flat roofs deal with rain in a very different way from pitched ones. Water lies on the surface for longer, so a small split or a blocked outlet can soon lead to a leak. We check the surface, the falls, the upstands and the edge trims, and we look for signs that water has reached the deck. That way, defects are found before they reach the room below. We survey mastic asphalt, GRP fibreglass and single-ply membranes, and people most often book us about dips that suggest the deck is deflecting and pools of water lying on the roof.
On a London roof terrace or a flat roof over a back addition, water often runs under the covering before it shows. Upstands against parapets, outlets and the edge where flat meets pitched are common entry points. In a converted house in Long Ditton, the roof above may belong to the building rather than one flat.
You can share the report with anyone who needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent, whichever applies.

Common questions in Long Ditton
How do I find out if my home in Long Ditton is listed?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it’s in a conservation area. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Is Long Ditton in the area you cover?
Yes, Long Ditton is within the area we cover. We work right across London and South East England. Just phone 07833 053749 or send us an email and let us know about the property.
Do I have to be there for the survey?
Not always. An outside-only look can be arranged beforehand, but the loft and any rooms with damp need someone to let us in.
How do I arrange a flat roof survey in Long Ditton?
It’s easiest to call 07833 053749 or send us an email. Let us know the address and a little about the roof, and we’ll recommend the right survey. We survey on weekdays, Saturdays and Sundays.
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. Where nothing visible explains the leak, the report says what to try next.
Which flat roof coverings do you cover?
Felt, asphalt, EPDM, GRP and single-ply roofs are all covered. If you don’t know what your roof is, we’ll identify it on the day.
Is ponding on a flat roof a problem?
Ponding is worth looking into. It often means a blocked outlet, poor falls or a dipping deck, and water that sits wears the covering sooner. We record where it sits and the likely cause.

Do you need a flat roof survey in Long Ditton?
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.
Things that frequently lead to a survey include:
- Edge trims that have lifted or split
- Outlets choked with leaves and silt
- Raised blisters across the surface
- Failed seals around rooflight kerbs
Landlords with a home close to Surbiton station may find that flat roofs over rear additions and dormers in rented property are worth checking between tenancies.
Choosing a roof surveyor
- Will they check the loft as well as the outside?
- What exactly goes into their report
- Whether VAT is in the quoted price
- Their report turnaround times
Why act early in Long Ditton
Before replacing a flat roof, it’s useful to know if you really need to. Sometimes a few details are to blame, and sometimes the covering has simply had its day. Our report gives you the evidence to discuss with a roofer. London’s older roofs frequently have bitumen felt underlay or none at all, so once the slates or flashings let water past, little stops it reaching ceilings. Left unchecked, water soaks into timber and plaster and the damage spreads.
Simple, low roofs take less time to survey than tall or complicated ones, and the package matters as well. The price is always agreed first.
Why book us in Long Ditton
- Surveys seven days a week
- Every finding written up with photos
- 5,000+ roofs surveyed
- An independent look at the roof

Can I check my roof myself?
Your own check is a good start, but it isn’t a survey. You won’t see flashings, valleys or the backs of chimneys properly from ground level.
Keep a simple record: dates of leaks, photos from the ground and any work done on the roof. Send it with your enquiry.
Local flat roofs in Long Ditton
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 Long Ditton 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. Hampton Court Palace, about 1.5 miles north-west, is one of the historic houses in the wider area around Long Ditton. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and a listed home or one in a conservation area may need consent for changes of material.
If you look after a building such as Long Ditton Infant and Nursery School, schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks. If your house is among the older ones in the streets near Church of St Mary, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear.

How it works
It helps to start with what’s prompted the survey: a purchase, a leak, a storm, new work or simply peace of mind. That way we can focus on what matters to you. Most visits take roughly 1–2 hours at a typical home, while a commercial roof takes nearer three to four hours. For a visit in Long Ditton, parking and access are the things to plan: let us know about permits, visitor bays or off-street space, which floor the property is on and how to get into the loft. On the day, the roof is looked at from the ground, from windows, from inside the roof space and from the roof where it’s safe.
- First we go through the roof, what’s beneath it and any problems so far.
- The roof is viewed from safe positions, including the roof itself where that is safe.
- We check the covering for splits, blisters, ponding and wear.
- Upstands, outlets, edge trims and rooflights are checked and photographed.
- The report, with photos and recommendations, comes to you by email.
Before the survey
- For a flat or shared roof, check access with the building owner or managing agent
- If it isn’t your property yet, arrange access through the agent
- Note where any stains or damp appear
Book a survey
Buyers should book once an offer has been accepted, so you have the findings in time to act on them before you exchange. Otherwise, simply phone 07833 053749 or send us an email whenever suits you.

Landlord and commercial surveys in Long Ditton
For blocks of flats, a roof survey helps managing agents and residents’ management companies plan ahead. Recommendations are set out by urgency where it matters, which helps when budgeting.
If the property is let, the agent or a tenant can let us in, at a time agreed in advance. Surveys run on any day of the week, which helps when tenants work during the week.
Different roofs, different checks
GRP fibreglass
GRP can crack if the deck beneath flexes or if the resin was laid too thin. Our report notes cracks and any sign that the deck is flexing.
Felt and built-up roofs
Built-up felt is one of the most common flat roof coverings on extensions, garages and dormers. We look for blistering, cracking, split laps and worn mineral surfacing.
