Flat roof survey in Sanderstead
Every flat roof covering tends to fail in its own way. Felt can blister and crack, asphalt can craze and split, EPDM seams and laps can lift, and GRP can crack where boards meet or at the 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. If you’ve noticed blocked or damaged outlets and damaged trims at the roof edge, we can find out what’s behind it, whatever the roof.
Across London, flat roofs are everywhere, from back additions and dormers to roof terraces, blocks of flats and offices. They’re covered in felt, asphalt, EPDM rubber, GRP fibreglass or single-ply membranes, and each fails in its own way. In Sanderstead, as anywhere in London, the right approach depends on what the roof is made of. Older flat roofs are frequently felt or asphalt, newer ones rubber or GRP.
Where we cannot see part of the flat roof, the report says so. You’ll know exactly what was inspected and what wasn’t, and what we’d suggest next.

Sanderstead: your questions answered
How do I find out if my home in Sanderstead is listed?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Can parking be tricky for a visit in Sanderstead?
Typically it’s manageable with a little notice. Let us know the parking rules on your street and we’ll work around them.
Will the survey show why my flat roof is leaking?
The survey covers the covering and all the details where leaks normally begin, and photograph anything that could be letting water in. If the source is hidden, we may suggest a leak investigation or electronic leak detection.
Does the survey cover asbestos?
Asbestos testing is not part of our survey. Where a roof has materials that might contain asbestos, such as old cement sheeting, the report flags them so a specialist asbestos surveyor can check them.
Does the report include photographs?
Yes. Photos are part of every report, so you can see exactly what each finding refers to.
Can you survey a flat roof on an office or unit?
Yes. Offices, units, shops and blocks of flats are all part of our work. We quote bigger roofs on their size and how they’re reached, so ring 07833 053749 or drop us an email with the address.
Do you survey on Saturdays and Sundays?
Surveys run on any day of the week. To find a day that suits you, phone 07833 053749 or email us.
Can I check my roof myself?
During heavy rain, look at the gutters from the ground or a window. Overflowing water can be a sign of a blockage or a gutter that has dropped.
Inside, the loft is a good place to look, with care. Take a torch and only step on boards or joists, checking for stains, damp wood or chinks of daylight.
How the survey works
Every visit follows the same pattern: we hear what you’ve seen, inspect the roof from each safe vantage point, photograph what we find and record our findings for the written report. It typically takes an hour or two for a small flat roof at home, and longer for a large commercial one. In Sanderstead, as in much of London, plenty of properties are flats or terraces without side access, so rear slopes are viewed from windows, the loft or, where a flight is allowed, by drone. If the building has a managing agent or access rules, let us know when you book.
- 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.
- The covering is checked for wear, splits, blisters and standing water.
- Upstands, outlets, edge trims and rooflights are checked and photographed.
- The report, with photos and recommendations, comes to you by email.
Before the survey
- Move anything stored under the loft hatch
- Check pets are kept safely away
- If you are buying, check with the agent that we can get in

Useful tips for Sanderstead property owners
Some practical points come up on survey after survey. They apply to most roofs:
- Ask whoever fits equipment on the roof to make good the covering
- Watch the ceilings below the flat roof for stains
- Note where water lies after a downpour
- Keep people off the roof unless they need to be there
Buyers can take the findings back to the seller or the agent. It can support a request for work before completion or a conversation about price, depending on the findings.
Get splits, lifted seams and loose trims seen to while they’re small. Prompt repairs tend to add years to a flat roof.
What affects the cost of flat roof surveys
To price your survey, we look at:
- The type of building, from a house to a block or an office
- How big the roof is
- Whether thermal imaging or a drone is needed
- How tall the building is and how easy the roof is to see
The Premium Survey includes thermal imaging and drone inspection where it applies, which starts from £400, including VAT. We can help you choose the package that fits what you need to know.
What to tell us when you get in touch
You don’t need to know any roofing terms. Just let us know:
- Access details, such as a loft hatch or a shared roof
- Pictures from the garden or a window, if you have them
- Where water is showing inside, if it is
- Where the property is, with the postcode
Photos help, if you have them. Pictures from ground level or a window are fine, and please don’t climb up for a closer look. To send them or to book, phone 07833 053749 or email us.

What happens if roof problems are left?
Standing water on a flat roof rarely sorts itself out. It usually points to an outlet, the falls or a sagging deck, and every wet spell adds to the wear. Finding the cause now keeps more options open. In Sanderstead, as across London, an overflowing gutter soaks the wall below. A blocked outlet ignored for a winter or two can mean damp walls inside.
What a survey costs comes down to the roof itself: how big it is, how high it is, the number of separate roofs and how it can be reached and seen safely. Flat roof survey starts from £150, including VAT.
