About our flat roof survey in St Margarets
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. Common reasons to book are water getting in at rooflights and damaged trims at the roof edge, across EPDM rubber, felt flat roofs and GRP fibreglass.
Water getting through a flat roof in London can travel under the covering and appear some way from the hole. Outlets, upstands against parapet walls and joins with the main roof are frequent culprits. In a block or conversion in St Margarets, the flat roof is often a shared part of the building.
The report does not just list problems. It explains what we found, why it matters and what we recommend, so you can decide what to do next.

How the survey works
We will ask a few questions first, about the roof’s history, any leaks and past repairs. The inspection then takes between one and two hours for a small flat roof at home, and longer for a large commercial one. In St Margarets, as in much of London, lots 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, tell us when booking.
- 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.
Getting ready for the survey
- Jot down any questions you want answered
- Agree roof access with the managing agent if it’s shared
- Make sure the loft hatch can be reached

Prices for flat roof surveys in St Margarets
What a survey costs depends on the time and equipment it needs. That comes down to:
- The roof’s overall size
- Chimneys, valleys, parapets and other details
- How many separate roofs there are, such as extensions, dormers and garages
- How tall the building is and how easy the roof is to see
The cost of a survey depends on the roof: its size, its height, how many sections it has and how it can be reached and seen safely. Prices start from £150, including VAT.
What we need to know
These details help when you contact us:
- Your postcode, so we can check access and travel
- Access details, such as a loft hatch or a shared roof
- Pictures of the roof from a safe spot, if you have them
- Any deadline, like an exchange date
If you have photos of the roof, send them over. Take them safely from ground level or a window. To get started, ring 07833 053749 or drop us an email.
How the survey changes by roof type
Single-ply membranes
Many offices, units and newer flats have a single-ply PVC or TPO roof. We check the welded laps, the edges, the fixings and any punctures.
Mastic asphalt
Mastic asphalt is a heavy, seamless covering frequently found on older blocks, balconies and commercial roofs. We look for crazing, cracks, blisters and splits at the skirtings.
Why act early in St Margarets
If you are buying, find out about the flat roof before you exchange. After that, the cost of any work is yours. A report gives you facts to put to the seller or agent. London’s older roofs often have bitumen felt underlay or none at all, so a slipped slate can soon mean water inside. Left alone, that means wet timbers and plaster, which is a far bigger job than the roof fault itself.
A Basic Survey starts from £150, inc. VAT. Standard is from £250 and Premium from £400, both inc. VAT. We confirm the exact price before booking.

Every survey has limits, and it is better to know them up front. Keep these in mind:
- Testing older roof sheets for asbestos
- Areas we can’t see or reach safely, including fragile rooflights and sheeting

If in doubt, ring 07833 053749 or send us an email and we’ll recommend the right survey. The full list of what we check.

Flat roof surveys around St Margarets
There are several hotels within about a mile and a half of St Margarets, and like offices and blocks, hotels often sit under flat roofs. For hotels and other commercial buildings, finding the cause of a flat roof leak quickly keeps rooms in use. Historic houses like Richmond House, about 1 mile south, show how far back building in the area around St Margarets goes. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs.
Hotels and guest houses near St Margarets can’t easily close rooms for a leak, so it’s worth knowing the roof’s condition. Controlled parking zones are common in London, so mention any permit rules for St Margarets, along with any off-street space. Anyone responsible for a site like Worple Primary School will know that a large flat roof with lots of outlets and rooflights has many places where a membrane can fail.

St Margarets questions
Can parking be tricky for a visit in St Margarets?
London parking needs a little planning, so let us know about permits, bays or a driveway when booking. The visit is then planned around what’s available.
Is my home in St Margarets listed or in a conservation area?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you’re planning to re-roof in a different material.
Do you give a life expectancy for the roof?
There’s no honest way to give an exact number of years. As a guide, felt frequently lasts around 15 to 20 years, EPDM frequently 30 to 50 and GRP up to about 30, but the report tells you how your roof is really doing.
Does the report include photos?
Yes, plenty. Pictures sit next to the findings they show, which makes the report easy to follow.
Which days do you carry out surveys?
We survey seven days a week: Monday to Friday, Saturdays and Sundays. Tell us which days suit you when you book.
How quickly is the report sent?
Basic reports arrive within 48 hours, Standard reports in 24–48 hours and Premium reports on the same day. All of them come by email.
Does the survey cover asbestos?
We don’t carry out asbestos surveys. Buildings built or refurbished before 2000 may contain asbestos, for instance in cement roof sheets. We note anything that could contain it, and a specialist asbestos surveyor should check it before it is disturbed.

Should I look at the roof myself first?
Look up at the roof after a storm, from ground level: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Don’t go up yourself.
The one thing to avoid is getting up close. Roofs are fragile and slippery, and falls from height are serious. That part is for a survey, using safe viewpoints and a drone where applicable.
