Flat Roof Survey in Merton Park
A careful look at the flat roof at your property in Merton Park, and put it all in a report with photographs.
- Outlets that hold water back
- Upstands pulling away from walls
- Pools of water lying on the roof
For landlords and managing agents
If the property is let, the agent or a tenant can let us in. Surveys run on any day of the week, which helps when tenants work during the week.
Letting agents frequently book on a landlord’s behalf, with the report sent to whoever needs it. Access is agreed with the tenant in advance.
Flat roof survey in Merton Park: what you get
Offices, shops, industrial units and blocks of flats frequently sit under large flat roofs. On a roof like this, a survey shows where the covering is wearing, where water is ponding and which outlets need attention. The photographed record helps you plan and budget for work. We quote commercial roofs on their size and how they’re reached, so it helps if you phone 07833 053749 or drop us an email with the address and a rough idea of the roof area. We survey GRP fibreglass, single-ply membranes and felt flat roofs, and people most frequently book us about loose or cracked edge trims and blisters and bubbles in the covering.
On a London roof terrace or a flat roof over a back addition, water often runs under the covering before it shows. Upstands against parapets, outlets and the edge where flat meets pitched are common entry points. In a block or conversion in Merton Park, the flat roof is often a shared part of the building.
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 it applies, structural analysis and an in-person consultation.

Can I check my roof myself?
It is useful to keep a record: dates of leaks, photos from the ground and any work done on the roof. Share it with us when you book, as it helps us focus the survey.
What you can’t do safely is get up close. Slates, tiles, flat roofs and rooflights can give way, and a fall can be serious. That part is for a survey.
Honest limits
It is useful to know what a survey will not do before booking:
- A structural engineer’s assessment of the deck
- A fixed date for when the roof will need replacing
- Areas we can’t see or reach safely, including fragile rooflights and sheeting
Not sure which survey suits your roof? You can call 07833 053749 or send us an email and we will tell you. What our survey covers.
What this survey covers
- GRP fibreglass
- Upstands and outlets
- Single-ply membranes
- Felt flat roofs
- Mastic asphalt
- EPDM rubber
Before and after the survey
Some practical points come up on survey after survey. They apply to most roofs:
- Keep outlets clear of leaves and moss
- Keep records of when the roof was laid and what work has been done
- Book a survey every few years
- Note any new marks on ceilings beneath the roof
After the visit, we write up the report with photos of what we found. It covers the type of covering, its condition and each defect, with our recommendations. Turnaround is within 48 hours for a Basic Survey, 24 to 48 hours for a Standard Survey and the same day for a Premium Survey.
Get splits, lifted seams and loose trims seen to while they’re small. Prompt repairs tend to add years to a flat roof.
Common questions in Merton Park
Does a conservation area affect roof work in Merton Park?
Start with Historic England’s list for listing and your council for conservation areas. It is worth checking before planning roof work, as both can affect what’s allowed.
Do you cover Merton Park?
Yes, Merton Park is one of the places we work. The survey and report are the same in Merton Park as anywhere else.
Do you cover flat roofs on blocks of flats?
Yes. Commercial and residential flat roofs are both covered. Expect about 3 to 4 hours on site for most commercial roofs, with larger roofs quoted on their size.
How long is the visit?
That depends on the size and shape of the roof, but most surveys take about one to two hours for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. The written report follows by email.
What do I do with the report?
You receive the written report by email, with photographs and recommendations. You can use it to talk to a seller, an insurer, a roofer or a managing agent, whichever applies.
Does the weather affect the survey?
Light rain doesn’t usually stop a survey, and it can even help show where water is getting in. Strong wind or heavy rain can stop drone flights and make roof access unsafe, so we will agree a new date if the weather is not suitable.
Can you give me structural calculations?
No. We’re experienced roof surveyors, and visible signs such as sagging are noted, but calculations and an engineer’s opinion are outside what we do. The report will say if you need an engineer.

What we do, step by step
The visit has one job: to look at the flat roof as closely as is safe and record what we find. Notes and photos go into the written report. It normally takes about 1–2 hours at most homes; commercial roofs usually need 3–4 hours. In a London area like Merton Park, the main things to sort out are parking and access: let us know about parking, the floor the property is on, any shared entrance and loft access. We then look at what can safely be seen from ground level, windows, the loft and, where it’s safe, the roof itself.
- You tell us about the roof, its covering if you know it, and any leaks.
- We look at the roof from wherever it can be seen safely.
- Every part of the roof we can see is checked: covering, falls, upstands, outlets, trims and rooflights.
- Inside, we look for damp and staining under the roof where there is access.
- The findings are written up with photographs and recommendations and emailed to you.
Before the survey
- Leave side gates unlocked
- Gather any invoices or paperwork from past roof work
- Let us know about parking near the property
Booking a survey
Prices start from £150, including VAT. What you pay depends on the roof’s size, access and the package, so ring 07833 053749 or send us an email with the details.

Flat roof surveys around Merton Park
Outer London has lots of Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, often with hipped roofs in clay or concrete tiles. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. With Southside House about 1.4 miles west, Merton Park sits in an area with a long building history. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and any change of roofing material on a listed home needs checking with the council first.
If you own a rental within reach of South Merton station, the flat roof over a let home is worth a look before it becomes a tenant complaint. Merton Park is in London, so parking needs planning: a visitor permit or a nearby bay makes the day easier, as a space near the door can’t be promised. Take an older house close to St Mary's Church: any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.
