Flat roof survey in Nash
If the house you’re buying has a flat roof on an extension, dormer or garage, it’s worth knowing its condition before exchange. Felt roofs often last around 15 to 20 years, while EPDM and GRP often last longer. We set out the type of covering, its condition and the defects we found, with a photo of every defect. That gives you facts to raise with the seller or agent. We survey mastic asphalt, upstands and outlets and EPDM rubber, and the problems we are asked to look at most are edge trims that have lifted or split and splits, cracks and crazing.
Across London, flat roofs are everywhere, from back additions and dormers to roof terraces, blocks of flats and offices. Coverings range from felt and asphalt to EPDM rubber, GRP fibreglass and single-ply membranes, and each fails in its own way. Which one is on a roof in Nash shapes how it is checked. Older flat roofs are often felt or asphalt, newer ones rubber or GRP.
It isn’t only a list of defects. It explains what we found, why it matters and what we recommend, so you can decide what to do next.

How we price flat roof surveys
Every roof is different, so prices are confirmed before you book. This is what makes a difference:
- Building height and the viewpoints available
- Features like valleys, chimneys, dormers and parapets
- How big the roof is
- Commercial roofs and larger buildings
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. Our price is from £150, including VAT.
What to tell us when you get in touch
A few details help us recommend the right survey and price. When you contact us, let us know:
- The address and postcode of the property
- When you need the report by
- What made you get in touch
- Any stains, drips or damp patches you’ve seen indoors
To book a survey, ring 07833 053749 or drop us an email with the address and what you’d like to know about the roof. You will know the price before anything is booked.
What we can’t see
It helps to know what a survey won’t do before you book:
- Hidden layers beneath the covering
- A promise that the roof won’t leak in future
- Structural calculations, which need a structural engineer
If you are not sure which survey you need, phone 07833 053749 or drop us an email and we’ll give you a straight answer. The full list of what we check.

What a flat roof survey looks like in Nash
Historic houses such as Down House, about 2.4 miles south-east, show how far back building in the area around Nash goes. If yours is one of the older homes, expect a mix of original materials and later repairs on the roof. In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
For landlords with property near Hayes (Kent) station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies. If you run a business near The Mall, flat roofs over shops and units are easy to forget until water comes through a ceiling.
Nash is about 3 miles south of Bromley, in Greater London. In Nash, as across Greater London, every roof gets the same careful survey. Across Greater London, we cover Nash. Our London page covers surveys nearby.

Why get it checked now?
Standing water on a flat roof rarely sorts itself out. Most often it means blocked outlets, poor falls or a deck that is dipping, and each wet season wears the covering further. Finding the cause now keeps more options open. Work on a London roof is rarely simple to arrange, with parking, neighbours and access all to think about. Knowing what’s needed early gives you time to plan it calmly, rather than in a rush after a leak.
Thermal imaging and drone inspection (where it applies) come with the Premium Survey, from £400 with VAT included. We can help you choose the package that fits what you need to know.

Before and after the survey
Small things make a difference, both for the survey and for the roof itself. Our tips:
- Clear roof outlets and gutters each autumn
- Watch the ceilings below the flat roof for stains
- Ask whoever fits equipment on the roof to make good the covering
- Never stand on rooflights or fragile sheeting
Buyers can take the findings back to the seller or the agent. You might ask for work to be done before completion, or discuss the price, depending on what we found.
Have the roof surveyed every few years, and after any work that goes through it. That catches changes early and builds up a record of the roof.
How it works
The aim of the visit is simple: to see as much of the flat roof as can safely be seen and record it clearly. Notes and photos go into the written report. The visit typically takes roughly 1–2 hours for a small flat roof at home, and longer for a large commercial one. From the street, a London terrace typically shows only its front slope or parapet, so a visit in Nash moves between viewpoints: the pavement, upstairs windows, the loft and any safe spot at the back. If other people live in the building, let us know who can let us into the shared parts.
- You let us know about the roof, its covering if you know it, and any leaks.
- The roof is inspected from safe viewpoints, and from the roof itself where that is safe.
- The covering, falls, upstands, outlets, edge trims and rooflights are checked and photographed.
- Inside, we look for damp and staining under the roof where there’s access.
- We send a written report with photos, the defects we found and what we recommend.
Preparing for the visit
- Let us know where we can park nearby
- For flats, make sure roof access has been agreed
- Keep pets out of the way during the survey
Getting a price
Buyers should book once an offer has been accepted, so there is time to use the report before exchange. Otherwise, simply ring 07833 053749 or email us whenever suits you.

When to book a survey in Nash
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.
These are some of the problems a survey can pick up:
- Water getting in at rooflights
- Blistering in felt or asphalt
- Blocked or damaged outlets
- Signs of deflection in the roof deck
The streets around a church such as Keston Parish Church are often among the oldest in a place, and if yours is one of the older homes nearby, the flat roofs on later extensions tend to wear out long before the main roof.

What else we do in Nash
Nash: your questions answered
Will parking be an issue for a roof survey in Nash?
It rarely stops a survey, but it is worth planning. Tell us what parking is available nearby, and the visit is planned around it.
Does a conservation area affect roof work in Nash?
Your council is the best source, with Historic England’s list for listed buildings. Both listing and conservation areas can limit changes of roofing material.
How do you inspect a flat roof?
Only where it is safe to do so. If not, we use safe viewpoints and look inside, and the report says if any part couldn’t be seen. Fragile surfaces are never walked on.
Do you carry professional indemnity insurance?
Our cover is professional indemnity plus public liability.
How many surveys have you done?
More than 5,000 surveys over 20+ years, across London and South East England.
Does someone need to be in?
Not always. If we only need the outside, we can agree that ahead of time, but anything inside needs someone there to give access.
Do you survey commercial flat roofs?
Yes. We survey flat roofs on offices, shops, industrial units and blocks of flats. Larger commercial roofs are quoted for their size and access, so phone 07833 053749 or use the contact form with the address.
