Flat roof survey in Dorking: what you get
Ponding is frequently the first sign that something on a flat roof is not right. It can mean the falls were never right, an outlet is blocked or the deck has started to sag. The survey notes any ponding, the state of each outlet and any dips that hint at a sagging deck. Where the deck may be a structural issue, our report says a structural engineer should look at it. If you’ve noticed edge trims that have lifted or split and outlets that hold water back, we can find out what’s behind it, whatever the roof.
In a town like Dorking, flat roofs are common on rear extensions, garages, porches and dormers. Older ones are often felt, which frequently lasts around 15–20 years, while newer ones may be EPDM rubber or GRP fibreglass. The usual warning signs are standing water, splits and edges coming away. Water that sits for days after rain is often the first sign a flat roof needs attention.
The Standard Survey adds moisture detection, a structural check and a follow-up consultation. The Premium Survey goes further, with thermal imaging, drone inspection where it applies, structural analysis and an in-person consultation.

What a flat roof survey does not cover
No survey can tell you everything, and we’d rather be clear about that before booking. Bear these in mind:
- Fragile surfaces, which we do not walk on
- Structural calculations, which need a structural engineer
- Testing older roof sheets for asbestos

What else we do in Dorking
For landlords and managing agents
Letting agents often book on a landlord’s behalf, and the report can go to both. Access is agreed with the tenant ahead of time.
If the property is let, the agent or a tenant can let us in. Surveys run on weekdays, Saturdays and Sundays, which helps when tenants work during the week.
Flat and commercial roofs around Dorking
There are several hotels within about a mile and a half of Dorking, and hotels, like offices and blocks of flats, frequently have flat roofs. For hotels and other commercial buildings, finding the cause of a flat roof leak quickly keeps rooms in use. Polesden Lacey, about 2.7 miles north-west, is one of the historic houses in the wider area around Dorking. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead.
Anyone responsible for a site like St Paul's CofE (Aided) Primary School will know that a large flat roof with plenty of outlets and rooflights has many places where a membrane can fail. If you run a hotel or guest house in or near Dorking, a roof problem can mean rooms out of use.

Different roofs, different checks
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.
Rooflights and upstands
Upstands at walls and parapets need to stay watertight as the building moves. We look for splits, gaps and failed flashings over the top.
How the survey works
We look at the roof from outside and, where it’s relevant and there is safe access, from inside the loft space too. In the loft, the signs we look for are staining, damp, daylight and sagging, as far as the space allows. The whole visit typically takes about 1–2 hours on an ordinary house, with bigger or more complicated roofs taking longer. For a visit in Dorking, we need access to the loft, any rooms with leaks or stains, and the outside of the building. Mention gates, side passages and anything at the back. Visits can be on weekdays, Saturdays or Sundays.
- First we go through the roof, what’s beneath it and any problems so far.
- We check the roof from the ground, windows and the roof where it’s safe.
- We check the covering for splits, blisters, ponding and wear.
- Upstands, outlets, edge trims and rooflights are checked and photographed.
- A written report with photos and recommendations is emailed to you.
Preparing for the visit
- Check the loft hatch can be reached
- For flats, make sure roof access has been agreed
- Dig out any old roof reports or invoices

Signs you need a flat roof survey in Dorking
People go onto flat roofs for all sorts of reasons: cleaning windows, fitting aerials or air conditioning, or clearing gutters. Each visit can damage a covering not made for regular foot traffic. New brackets and fixings through the roof are another common source of leaks.
Typical things we are asked to look at include:
- Upstands pulling away from walls
- Standing water left after rain
- Splits and cracks in the covering
- Outlets that hold water back
If you own a rental within reach of Dorking Deepdene station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.

Your questions about flat roof surveys in Dorking
Can you look at the flat roof of a hotel or office near Dorking?
Yes, we cover commercial roofs as well as homes. Access to the roof is sorted out with whoever manages the building before the day.
Do you cover Dorking?
Yes. Our area covers London and South East England, and Dorking is part of that. You can phone 07833 053749 or email us with the address and some details.
How experienced are you?
More than 5,000 surveys over 20+ years, across London and South East England.
How fast do I get the report?
Basic reports arrive within 48 hours, Standard reports in 24–48 hours and Premium reports on the same day. Each one is emailed, ready to forward.
Is this a RICS survey?
No. Our survey is a roof survey, not a RICS Level 2 or Level 3 survey of the whole building. It focuses on the roof, so it sits alongside a building survey rather than replacing it.
What happens after the survey?
The report arrives by email. With Standard there’s a follow-up consultation; with Premium, an in-person consultation, so you can talk the findings through.
Will you walk on the roof?
Not unless it’s safe. Most of what we need can be seen from safe viewpoints, the loft and, where it applies, a drone.
