Flat roof survey in Hamsey Green, Surrey
Get a clear view of the flat roof at a property in Hamsey Green. Visits run on weekdays and weekends, in the daytime.
- Gaps at upstands and abutments
- Splits and cracks in the covering
- Outlets choked with leaves and silt
How the survey changes by roof type
Single-ply membranes
Single-ply relies on its welded laps staying sound. We check seams, corners and the joints around outlets and upstands.
Rooflights and upstands
Where a flat roof meets a wall, the upstand has to stay sealed as the building moves. We check for splits, gaps and loose flashings above the upstand.
Flat roof surveys for homes and businesses in Hamsey Green
Water through a flat roof does not always come in where the stain is. It may start at a split, a lifted seam or a failed upstand well away from the damp patch. That’s why we check every detail across the roof, not only the area above the stain, and photograph anything that could let water in. Whoever carries out the work then has a clear starting point. We survey GRP fibreglass, upstands and outlets and single-ply membranes, and people most often book us about raised blisters across the surface and failed seals around rooflight kerbs.
Flat roofs on exposed homes in small places like Hamsey Green take more wind and rain, so edges, upstands and laps take a beating. Felt roofs, which often last around 15–20 years, typically show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. Exposed edges are usually the first part of a flat roof to go.
Where we can’t see part of the flat roof, the report says so. You will know exactly what was inspected and what wasn’t.

How the survey works
The aim of the visit is simple: to look at the flat roof as closely as is safe and record what we find. Notes and photographs go into the written report. It usually takes about 1–2 hours for a small flat roof at home, and longer for a large commercial one. Cottages and farmhouses around Hamsey Green often have roofs at several levels, with lean-tos and outbuildings attached. We work round each section in turn, from the safest viewpoints, and anything we can’t see is noted.
- 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’s safe.
- We check the covering for splits, blisters, ponding and wear.
- We photograph and record the outlets, upstands, trims and rooflights.
- The report, with photos and recommendations, comes to you by email.
Before we arrive
- If you’re buying, check with the agent that we can get in
- Dig out any old roof reports or invoices
- Keep pets in another room

Flat and commercial roofs around Hamsey Green
Historic houses like Addington Palace, about 2.8 miles north, show how far back building in the area around Hamsey Green goes. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and the council can say whether a home is in a conservation area. Many older homes in Surrey have handmade clay tiles and tile-hung upper walls. A few of Surrey’s oldest buildings have heavy Horsham stone slab roofs. Next to the main roofs there’s usually a flat roof somewhere, whether on an extension, a garage or a commercial unit.
If yours is one of the older homes in the streets near St Antony, the joins between later flat roofs and the old walls are where problems normally start. For landlords with property near Upper Warlingham station, the flat roof over a let home is worth a look before it becomes a tenant complaint.

What we are asked to look at in Hamsey Green
A buyer’s general survey often recommends a closer look at a flat roof. Owners and managing agents use a survey to plan upkeep, or ahead of a sale or a new lease. In each case, the report gives a written, photographed record of the roof’s condition.
Look out for signs like these:
- Dips that suggest the deck is deflecting
- Damaged trims at the roof edge
- Splits, cracks and crazing
- Ponding water that does not drain away
Take a building like Hamsey Green Primary: ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.

Tips from our surveys
A few practical points come up again and again on our surveys. They apply to most roofs:
- Look for standing water a day after rain
- Note the date and type of any roof work
- Watch the ceilings below the flat roof for stains
- Keep clear of rooflights and fragile roof sheets
The report is emailed to you, ready to share with a roofer, the seller or a managing agent. It is written in plain English, with a photo of each defect, so others can follow it without going up to look.
Get splits, lifted seams and loose trims seen to while they’re small. Prompt repairs tend to add years to a flat roof.
What this survey can’t tell you
This isn’t a RICS building survey, a structural engineer’s report or an asbestos survey. It also has these limits:
- Hidden layers beneath the covering
- Asbestos testing, which needs a specialist asbestos surveyor
- A fixed date for when the roof will need replacing
If you are not sure which survey you need, phone 07833 053749 or drop us an email and we will give you a straight answer. What a survey covers and does not.
What we look at
- Upstands and outlets
- Felt flat roofs
- Mastic asphalt
- GRP fibreglass
- EPDM rubber
- Single-ply membranes

Checking the roof from ground level
A DIY look is useful, but it isn’t a survey. You won’t see flashings, valleys or the backs of chimneys properly from ground level.
A lot can be seen from the ground. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Never climb onto the roof to look.
Hamsey Green: your questions answered
Do you cover Hamsey Green?
Yes, Hamsey Green is within the area we cover. We work right across London and South East England. You can phone 07833 053749 or send us an email with the address and a few details, and we will talk through which survey suits.
Does a conservation area affect roof work in Hamsey Green?
For listing, use Historic England’s list; for conservation areas, ask the council. The answer matters most when a change of material is on the cards.
What insurance do you have?
We are covered by professional indemnity and public liability insurance, for every survey we carry out.
Will you check the loft?
If it is needed and safe to reach, yes. We look for staining, damp, daylight and signs of movement, as far as the space allows.
Can you test old roof sheets for asbestos?
Asbestos testing is not part of our survey. Where a roof has materials that might contain asbestos, like old cement sheeting, the report flags them so a specialist asbestos surveyor can check them.
What does ponding on a flat roof mean?
Standing water a day or two after rain normally needs attention. It could be the outlets, the falls or a deflecting deck. We check each of these and record what we find.
Does a flat roof survey replace a RICS survey?
No. It is a closer look at the flat roof, not a survey of the whole property. It works alongside a RICS home survey, not instead of one, and it is not a structural engineer’s report.
