Flat roof survey in Box Hill
Our Basic Survey, from £150, gives you a visual inspection with photos and written recommendations. For moisture detection and a structural check, the Standard Survey starts from £250. Moisture readings are useful on flat roofs, where water can spread under the covering before it shows inside. Bigger commercial roofs are priced on their size and access. If you are worried about a sagging deck under the covering and outlets choked with leaves and silt, a survey will tell you what’s going on, whatever the roof.
In a village or hamlet like Box Hill, flat roofs are normally on extensions, garages, outbuildings or barn conversions. The checks are the same as anywhere: the covering, the edges, the upstands and where water drains away. The journey and access are planned beforehand. If there are outbuildings or garages with flat roofs, mention them when booking.
The report records the flat roof as we found it on the day. That makes it useful now and a handy reference later, like when you want to compare after future work.

Useful tips for Box Hill property owners
Most of what helps is simple and safe from ground level. Our suggestions:
- File the paperwork for the roof and any repairs
- Check ceilings under the roof for damp patches
- Plan a survey before the covering reaches the end of its usual life
- Limit foot traffic on the covering
Landlords, owners and managing agents can keep the report as a dated record of the roof. It is useful when planning upkeep and setting budgets, and it makes changes easy to spot at the next survey.
Get splits, lifted seams and loose trims seen to while they’re small. A flat roof that’s looked after between surveys typically lasts longer.
How the survey works
Photographs are taken throughout the visit, so the report shows exactly what we saw. We take close-ups from wherever is safe. Most surveys take an hour or two for a house, and longer for a large or complex roof. Somewhere as small as Box Hill, access is often the only tricky part. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Visits can be on weekdays, Saturdays or Sundays.
- We agree the roof to be surveyed, its use and any leaks you know about.
- We check the roof from ground level, windows and the roof where it is safe.
- The covering is checked for wear, splits, blisters and standing water.
- We photograph and record the outlets, upstands, trims and rooflights.
- A written report with photos and recommendations is emailed to you.
Preparing for the visit
- Tell us where we can park nearby
- For a flat or shared roof, check access with whoever owns or manages the building
- Leave a clear route to the loft

How the survey changes by roof type
Mastic asphalt
Without seams, asphalt tends to fail through cracking and at its skirtings. Our report notes crazing, cracks and any likely entry points.
Felt and built-up roofs
Many extensions, garages and dormers have a felt roof laid in layers. We look for blistering, cracking, split laps and worn mineral surfacing.
FAQs for Box Hill
Is Box Hill in the area you cover?
Yes. We cover the whole of London and South East England, and Box Hill is part of that. Just ring 07833 053749 or drop us an email and let us know about the property, and we’ll talk through which survey suits.
Is Box Hill within the area you cover?
Yes, we do. We cover the whole of London and South East England, from towns to the smallest villages. The journey is planned ahead, so it’s useful to know about access.
What types of flat roof do you survey?
Felt, asphalt, EPDM, GRP and single-ply roofs are all covered. Not sure what yours is? We’ll tell you in the report.
What if it rains on the day?
It can, depending on the survey. Drone flights need calm, dry weather, and thermal imaging works best after a sunny day, with a dry roof and little wind. If the conditions aren’t right, we will talk to you about another date.
Can you survey at the weekend?
Visits run seven days a week in the daytime. Let us know your preferred days when you book.
Do you go up onto the roof?
It depends on what’s safe: the roof itself where that’s safe, plus windows, vantage points and the rooms below. Fragile rooflights and fragile sheets are never walked on.
I live in a flat. Can you survey the roof?
Yes. Shared roofs just need a little more planning. Mention it when you get in touch and we will plan the survey around it.
Local flat roofs in Box Hill
The wider area around Box Hill has a long history of building, with Polesden Lacey about 3.9 miles west. 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. 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. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
For site and facilities teams at buildings such as The Ashcombe School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season. Take an older house close to St. Andrew's Church: any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.
Box Hill is about 2 miles north-east of Dorking, in Surrey. Whether the building in Box Hill is a house, a flat or a commercial unit, we can survey the roof. Box Hill is one of the places in Surrey we cover. There is also a page for Crawley.
Flat roof surveys in KT20 work the same way as everywhere else we cover. We offer flat roof surveys to properties on Boxhill Road, Usherwood Close and Fort Road. We also cover Betchworth (1 mile south-east), Brockham (1 mile south), Buckland (1 mile south-east), Strood Green (2 miles south) and Headley (2 miles north).

Local landmarks in Box Hill
Locally, jobs take us to homes and businesses close to Brockham Limeworks. For rail, the closest station is Betchworth station, roughly 0.8 miles east. A little further out are Headley Court (2.8 miles north) and Reigate Priory Museum (3.6 miles east). Green spaces nearby include Colley Hill and Reigate Heath.
Checking the roof from the ground
Fresh stains on ceilings or walls after rain are worth noting. Photograph them and note the date, which helps when we check the roof.
A DIY look is useful, but it isn’t a survey. You will not see flashings, valleys or the backs of chimneys properly from the ground, and those are details a survey looks at closely.
Do you need a flat roof survey in Box Hill?
The details are often where a flat roof lets go first. Upstands, edge trims, outlets and the kerbs around rooflights move and weather differently from the rest of the roof. If they were rushed when the roof was laid, they’re often the first things to fail.
Typical things we are asked to look at include:
- Raised blisters across the surface
- Outlets choked with leaves and silt
- Dips that suggest the deck is deflecting
- Upstands pulling away from walls
Landlords with a home close to Betchworth station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round.
