Flat roof survey in Roundshaw: what you get
Buying a home with a flat-roofed extension, dormer or garage? It helps to know that roof’s condition before you 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 photos of each. You then have something specific to put to the seller or agent. We survey single-ply membranes, GRP fibreglass and EPDM rubber, and common reasons people get in touch are splits and cracks in the covering and dips that suggest the deck is deflecting.
London has a lot of flat roofs: rear additions, dormers, roof terraces and the roofs of blocks and offices. Coverings range from felt and asphalt to EPDM rubber, GRP fibreglass and single-ply membranes, each with its own weak points. Which one is on a roof in Roundshaw shapes how it’s checked. Older flat roofs are often felt or asphalt, newer ones rubber or GRP.
With the Standard Survey, you also get moisture detection, a structural check and a follow-up consultation. The Premium Survey goes further, with thermal imaging, drone inspection where applicable, structural analysis and an in-person consultation.

What affects the cost of flat roof surveys
A few things affect what a survey costs:
- The type of building, from a house to a block or an office
- Which survey package you book
- The roof’s overall size
- Chimneys, valleys, parapets and other details
Prices start from £150, including VAT. What you pay depends on the size and height of the roof, access and the package you choose.
What to let us know when you contact us
You don’t need to know any roofing terms. It’s enough to let us know:
- The address and postcode of the property
- What kind of property and roof it is
- What’s prompted the survey
- Any deadline, such as an exchange date
Photos help, if you have them. Take them safely from the ground or a window, and please don’t climb up for a closer look. To send them or to book, ring 07833 053749 or send us an email.
How the survey changes by roof type
Mastic asphalt
With age, asphalt can harden and crack with movement. We note where this is happening and how widespread it looks.
Felt and built-up roofs
On felt, the upstands and edge details frequently fail before the main surface. Every upstand and edge is looked at, with photos of any that have lifted or cracked.

The survey, step by step
On the day, we start by asking what you’ve noticed and what you’d like to know. After that, we look at everything we can see safely. Most surveys take roughly 1–2 hours for a house, and longer for a large or complex roof. In Roundshaw, as in much of London, a good many 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. Mention any building rules, key holders or managing agents when you book.
- You send us the address and, for commercial roofs, an idea of the roof’s size.
- We check the rooms or spaces under the roof for staining where there is access.
- The roof is inspected from every safe viewpoint, without walking on fragile surfaces.
- We record every defect with a photo and its likely cause.
- You get a report setting out the condition and our recommendations, in order of urgency.
Before we arrive
- Make sure the loft hatch can be reached
- Note where any stains or damp appear
- Have keys ready for side gates, garages or roof access doors

Advice
Rented homes, blocks and businesses
If the property is let, the agent or a tenant can let us in, at a time agreed beforehand. We survey on weekdays and at weekends, which can make access easier.
Surveys can also be booked by buyers’ agents acting for a client. Reports are emailed, so they’re easy to pass on.
Your questions about flat roof surveys in Roundshaw
Does a conservation area affect roof work in Roundshaw?
We can’t confirm that for you, but Historic England’s list and your council can. Both listing and conservation areas can limit changes of roofing material.
Can parking be tricky for a visit in Roundshaw?
It can be, so it is useful to let us know about permits, visitor bays or off-street space when booking. The visit is then planned around what’s available.
What happens after the survey?
You’ll receive the report by email, and you decide the next step: use it with a seller, an insurer, a roofer or a managing agent.
Will you check the loft?
Normally, if there is one and it can be reached safely. The loft space can show things the outside cannot, such as damp timbers, staining or daylight.
Does someone need to be in?
That depends on the survey. For inside areas and the roof space, someone has to give us access, while outside access can be discussed when booking.
Can you tell me how long my flat roof will last?
We don’t give a fixed number of years, because it depends on upkeep, weather and how the roof was laid. Our report describes the condition and what needs doing, and when.
Is a flat roof survey the same as a building survey?
No. It is a survey of the flat roof. It is not a RICS Level 2 or 3 survey of the whole building, and it isn’t a structural engineer’s report. It frequently sits alongside a buyer’s building survey.
Do you need a flat roof survey in Roundshaw?
A buyer’s general survey frequently recommends a closer look at a flat roof. Building owners and managing agents book to plan maintenance, or before a sale or a new lease. In each case, the report gives a written, photographed record of the roof’s condition.
People typically book a survey when they’ve noticed one of these:
- Edge trims that have lifted or split
- Leaks around rooflights
- Raised blisters across the surface
- Standing water left after rain
For businesses in and around places such as St George's Walk, outlets and upstands on commercial flat roofs are the places to check before trouble starts.
Before booking any roof surveyor
- How long they’ve been surveying roofs
- Whether the loft is part of the inspection
- Which parts of the roof they’ll actually see
- Whether VAT is in the quoted price
Flat roof surveys around Roundshaw
About 3.9 miles east lies Addington Palace, a reminder of how long the area around Roundshaw has been built on. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead. Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of clay or concrete tiles. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Mixed in with those pitched roofs are plenty of flat ones, over rear extensions, dormers, garages and shops.
If you run a hotel or guest house in or near Roundshaw, a roof problem can mean rooms out of use, so it’s worth knowing the roof’s condition. For an older house near a landmark such as St. Paul's, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.

Leave it or get it looked at?
Before replacing a flat roof, it’s useful to know if you really need to. At times the trouble is a handful of failed details, and at times the whole covering is worn. The report sets out what we found, so you can make that decision with a roofer. London’s older roofs often have bitumen felt underlay or none at all, so a slipped slate can soon mean water inside. Left unchecked, water soaks into timber and plaster and the damage spreads.
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how safely it can be seen. Prices start from £150, including VAT.
