About our flat roof survey in Dartmouth Park
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 frequently last longer. Our report records the covering, how it’s holding up and any defects we can see, with photos of each. You then have something specific to put to the seller or agent. Common reasons to book are raised blisters across the surface and upstands pulling away from walls, on felt flat roofs, upstands and outlets and GRP fibreglass.
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, and each fails in its own way. Which one is on a roof in Dartmouth Park shapes how it’s checked. Many older flat roofs are felt or asphalt, and many newer ones EPDM rubber or GRP.
The report does not just list problems. It explains what we found, why it matters and what we recommend, so you can plan your next steps.

Can I check my roof myself?
It helps to keep a record: dates of leaks, photos from the ground and any work done on the roof. Share it with us when booking and it will help the survey.
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it, as it helps a surveyor trace the cause.

Flat roof surveys around Dartmouth Park
With Witanhurst about 0.8 miles north-west, Dartmouth Park sits in an area with a long building history. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and any change of roofing material on a listed home needs checking with the council first. Many homes in inner London are Victorian and Edwardian terraces, often with Welsh slate roofs. A butterfly roof with a central valley gutter, tucked behind a parapet wall, is common on these houses. Shared chimney stacks, party-wall upstands and lead work come with this kind of house. Next to the main roofs there’s usually a flat roof somewhere, whether on an extension, a garage or a commercial unit.
If you live in an older home near Church of St Mary Brookfield, flat-roofed rear additions and dormers added over the years are worth checking. For businesses in and around places such as O2 Centre, flat roofs over shops and units are easy to forget until water comes through a ceiling.

What happens if roof problems are left?
Standing water on a flat roof rarely sorts itself out. It typically points to an outlet, the falls or a sagging deck, and every wet spell adds to the wear. Knowing the cause early gives you more choice over what to do. Any roof job in Dartmouth Park means planning around parking, neighbours and access. Knowing what’s needed early gives you time to plan it calmly, rather than in a rush after a leak.
A Basic Survey starts from £150, inc. VAT. The Standard Survey starts from £250 and the Premium Survey from £400. We confirm the price for your roof before you book.

FAQs for Dartmouth Park
Do you carry out roof surveys in Dartmouth Park?
Yes, Dartmouth Park is within the area we cover. We cover the whole of London and South East England. You can phone 07833 053749 or email us with the address and a few details.
Is my home in Dartmouth Park listed or in a conservation area?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it’s in a conservation area. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
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 are not right, we’ll talk to you about another date.
What will the report tell me?
It explains what we saw, what it means and what we’d suggest, with photos throughout. It also says if any part of the roof couldn’t be seen safely.
I live in a flat. Can you survey the roof?
Yes, if whoever owns or manages the building agrees access. On a shared roof we can only inspect the parts we are allowed to reach.
How experienced are you?
We have more than 20 years’ experience and have completed over 5,000 surveys across London and South East England.
How do I arrange a flat roof survey in Dartmouth Park?
It is easiest to phone 07833 053749 or email us. Tell us the address and a little about the roof, and we’ll point you to the right survey. Surveys run on any day of the week.
What this survey can’t tell you
This is not a RICS building survey, a structural engineer’s report or an asbestos survey. It also has these limits:
- A promise that the roof won’t leak in future
- Asbestos testing, which needs a specialist asbestos surveyor
- Whether the deck or joists are strong enough
If in doubt, ring 07833 053749 or send us an email and we will suggest the right survey. The full list of what we check.
Roofs we survey in Dartmouth Park
- Felt flat roofs
- Mastic asphalt
- Single-ply membranes
- EPDM rubber
- GRP fibreglass
- Upstands and outlets
How the survey works
There isn’t much for you to do on the day. Show us any stains, drips or problem areas you know about, and we’ll get on with the inspection. The survey itself takes between one and two hours at a typical home, while a commercial roof takes nearer three to four hours. Many London properties are flats or terraces with no 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 booking.
- First we go through the roof, what’s beneath it and any problems so far.
- We look at the roof from the ground, windows and the roof where it’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 photographs and recommendations, comes to you by email.
Before the survey
- Keep pets out of the way during the survey
- Dig out any old roof reports or invoices
- Move anything stored under the loft hatch
How to book
A quick phone call is typically the easiest start: phone 07833 053749 or drop us an email and we will ask a few questions about the roof. The price is agreed before a date is set.
Advice
When to book a survey in Dartmouth Park
A buyer’s general survey frequently recommends a closer look at a flat roof. Owners and managing agents use a survey to plan upkeep, or ahead of a sale or a new lease. In each case, the report gives a written, photographed record of the roof’s condition.
We’re often asked to look at:
- Blocked or damaged outlets
- Raised blisters across the surface
- Signs of deflection in the roof deck
- Upstands pulling away from walls
For site and facilities teams at buildings like Acland Burghley School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.
Before you book anyone
- Whether VAT is in the quoted price
- What insurance they carry
- How they’ll see the roof: from the ground, the loft, the roof or by drone
- What’s outside the scope of the survey
