Flat roof survey in Horsell, Surrey
Surveys of flat roofs on homes, extensions and commercial buildings for Horsell, from an experienced roof surveyor. Every survey comes with a written report and photographs.

- Edge trims that have lifted or split
- Pools of water lying on the roof
How a flat roof survey works in Horsell
Each type of flat roof has its own weak points. Built-up felt tends to blister and crack, asphalt crazes and splits, EPDM can lift at its laps, and GRP can crack at board joints and edge trims. Single-ply PVC and TPO roofs are checked at their welds, edges and fixings. Knowing what you have and how it’s doing helps you plan what comes next. Typical surveys look at cracked or split membrane and damaged trims at the roof edge, on GRP fibreglass, felt flat roofs and EPDM rubber.
Around a smaller place like Horsell, flat roofs usually cover extensions, garages and dormers. Even a small flat roof can let lots of water into the room below. Knowing the covering and how it was laid tells you what to expect from it. From an upstairs window, look for standing water, splits and edges coming away.
Every survey ends with a written report, with photos, sent by email. It explains the condition of the flat roof, the defects we found and what we recommend.

Roof by roof
Mastic asphalt
Asphalt roofs are common on older flats, walkways and commercial buildings. We look for crazing, cracks, blisters and splits at the skirtings.
Felt and built-up roofs
Felt roofs frequently last around 15 to 20 years, depending on how they were laid and looked after. Our report sets out its condition and the areas most at risk.
Common questions in Horsell
Do you carry out roof surveys in Horsell?
Yes. We work right across London and South East England, and Horsell is part of that. Just ring 07833 053749 or drop us an email and let us know about the property.
How do I find out if my home in Horsell is listed?
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.
Do I have to be there for the survey?
If the survey includes the loft or the inside of the building, someone needs to let us in. Access is agreed with you when booking.
What types of flat roof do you survey?
We cover the main flat roof coverings: felt, asphalt, EPDM, GRP and single-ply. The report names the covering and explains its condition.
Is it a structural engineer’s report?
No. We’re experienced roof surveyors, and visible signs such as sagging are noted, but calculations and an engineer’s opinion are outside what we do. If one is needed, the report says so.
How do I arrange a flat roof survey in Horsell?
To arrange a survey, ring 07833 053749 or use the contact form with the address, the type of property and what’s prompted the survey. We’ll confirm the price and agree a day with you.
How long will you be at the property?
It usually takes about 1–2 hours for a small flat roof at home, and longer for a large commercial one. You will then get the report by email, on the timescale of your package.
What you can safely check yourself
You can learn a lot 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.
A DIY look is useful, but it is not a survey. You will not see flashings, valleys or the backs of chimneys properly from ground level, and those are details a survey looks at closely.
What a survey costs
Survey packages start from £150, including VAT. The price for your roof depends on:
- Height and safe access
- Features like valleys, chimneys, dormers and parapets
- Whether thermal imaging or a drone is needed
- The size of the roof
Prices start from £150, including VAT. What you pay depends on how big and how high the roof is, how it can be seen safely and the package you choose.
Booking your survey
We’ll typically ask about:
- Pictures from the garden or a window, if you have them
- The kind of building and roof involved
- When you need the report by
- The reason for the survey, like buying, a leak or storm damage
Once you know what you need, ring 07833 053749 or send us an email. We’ll suggest a package, agree the price and find a date, weekday or weekend.
Flat roof surveys in Horsell: local notes
Historic houses such as Botleys Mansion, about 3.3 miles north, show how far back building in the area around Horsell goes. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and a listed home or one in a conservation area may need consent for changes of material. In Surrey, older roofs are often handmade clay tile, with tile-hanging on many upper walls. Some old buildings in Surrey and Sussex have Horsham stone slab roofs. Next to the main roofs there is typically a flat roof somewhere, whether on an extension, a garage or a commercial unit.
Take an older house close to Church of St Mary the Virgin: the joins between later flat roofs and the old walls are where problems typically start. Landlords with a home close to Woking station may find that a flat roof over a rented flat is easy to forget until the tenant reports a leak. Take a building like Woking High School: ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.

How it works
Expect us to ask a few questions before we start, such as when any problem began and what work has been done before. Then the inspection itself takes roughly 1–2 hours on an ordinary house, with bigger or more complicated roofs taking longer. Homes around Horsell often have gardens on more than one side, which gives us room to step back and see the roof. Let us know if any side is fenced off or hard to reach. The loft, where there’s safe access, completes the picture.
- We start with the address and, on larger roofs, the roof area and access.
- 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.
- Each defect is photographed and its likely cause noted.
- The report explains the condition and recommends what to do first.
How to prepare
- Have any questions written down, so nothing gets missed
- Tell us about parking before the day
- Keep pets in another room
