South Tottenham Flat Roof Survey
Not sure what state the flat roof is in? We carry out flat roof surveys in South Tottenham and across Greater London.
- Outlets choked with leaves and silt
- A sagging deck under the covering
- Gaps at upstands and abutments
What we look for on each type of roof
Felt and built-up roofs
The edges and upstands of a felt roof are usually where trouble starts. We check each one and photograph any that have split or pulled away.
Mastic asphalt
Asphalt roofs are common on older flats, walkways and commercial buildings. The survey checks for crazing, cracking, blistering and splits where the asphalt turns up the walls.
About our flat roof survey in South Tottenham
A flat roof leak often travels before it shows on the ceiling. It may start at a split, a lifted seam or a failed upstand well away from the damp patch. That is why we check every detail across the roof, not only the area above the stain, and photograph anything that could let water in. A roofer can then start from a clear picture of the problem. We are often asked to look into a sagging deck under the covering and blistering in felt or asphalt, across EPDM rubber, GRP fibreglass and felt flat roofs.
Commercial and residential blocks across London often have big flat roofs with plant, rooflights and access walkways. Every penetration and upstand is a place where a membrane can fail. For a building in South Tottenham, access is agreed with whoever manages the roof ahead of the visit. Rooflights, plant supports and pipe entries are common places for a membrane to fail.
Where we can’t see part of the flat roof, the report says so. That way, it’s clear what was covered and what wasn’t.

Flat roofs in South Tottenham
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. In a house like that, shared stacks, party-wall upstands and lead flashings all need looking at as far as they can be seen. Mixed in with those pitched roofs are lots of flat ones, over rear extensions, dormers, garages and shops. Bruce Castle, about 1.1 miles north, is one of the historic houses in the wider area around South Tottenham. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and the council can say whether a home is in a conservation area.
If you let a flat or house near Seven Sisters station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies. If you look after a shop, office or commercial unit, for example near The Mall Wood Green, the flat roofs over shops and commercial units are worth checking before a leak, not after.
South Tottenham is about 2 miles west of Walthamstow, in Greater London. From houses to flats and shops in South Tottenham, the roof can be surveyed on a weekday or at the weekend. Across Greater London, we cover South Tottenham. London is in our area too.
All of N15, N17 and N16 is within our area for flat roof surveys. We cover properties on Ida Road, Elmar Road and Grove Road. We also cover Seven Sisters (1 mile south), Tottenham Green (1 mile north), St Ann's (1 mile west), Tottenham Hale (1 mile north-east) and West Green (1 mile west). Larger places within reach include London (6 miles south), City of Westminster (6 miles south-west), Marylebone (6 miles south-west), Kensington (8 miles south-west), St Pancras (4 miles south-west) and Shoreditch (4 miles south).

Landlords, agents and block managers in South Tottenham
Roof problems in a rented home affect tenants as well as the building. A survey shows what needs attention, so you can plan the work around your tenants.
An agent can book and manage the survey for a landlord, and the report can go to both. Access is agreed with the tenant beforehand.
The survey, step by step
You do not need to do much on the day. Show us any stains, drips or problem areas you know about, and we will get on with the inspection. A typical survey takes roughly 1–2 hours at a typical home; commercial roofs usually need 3–4 hours. In a London conversion, the way into the loft space is often from a communal landing or the top flat. If that applies to your building, it helps to agree access with the neighbours or the managing agent first. Everything else is planned around the building, not the postcode.
- We agree the roof to be surveyed, its use and any leaks you know about.
- We check the roof from ground level, windows and the roof where it’s safe.
- We check the covering for splits, blisters, ponding and wear.
- Upstands, outlets, edge trims and rooflights are checked and photographed.
- The report, with photographs and recommendations, comes to you by email.
Before the survey
- Jot down any questions you want answered
- Mention any parking restrictions on your street
- Clear the way to the loft hatch
How to book
Surveys can be booked for weekdays, Saturdays or Sundays. To find a date that works for you, ring 07833 053749 or send us an email with the address and the days you’d prefer.
Advice
When to book a survey in South Tottenham
A buyer’s general survey often 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. Either way, you get a clear record of the roof, with photographs.
Typical things we are asked to look at include:
- Splits and cracks in the covering
- Water getting in at rooflights
- A sagging deck under the covering
- Ponding water that does not drain away
Anyone responsible for a site like Earlsmead Primary School will know that ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.
Choosing a roof surveyor
- How long they’ve been surveying roofs
- Their insurance cover
- Their drone registration, if they fly one
- How they plan to inspect the roof safely
Your questions about flat roof surveys in South Tottenham
How do I find out if my home in South Tottenham is listed?
Start with Historic England’s list for listing and your council for conservation areas. It’s worth checking before planning roof work, as both can affect what’s allowed.
Can parking be tricky for a visit in South Tottenham?
Usually it’s manageable with a little notice. Tell us what parking is available nearby, and the visit is planned around it.
Can you survey a shared roof?
Yes, as long as access is agreed. Roofs over flats are often shared, so we need permission from the freeholder or managing agent. We can only inspect what we’re given access to.
Will the survey show why my flat roof is leaking?
The survey covers the covering and all the details where leaks normally begin, and photograph anything that could be letting water in. Where the source isn’t obvious, a roof leak investigation or electronic leak detection may be the next step.
How much is a survey?
Our price is from £150, including VAT. The final figure depends on the roof and the package you choose.
Does the report include photos?
Yes, every report has them. Each finding is shown in a picture where possible, so you can see what we mean.
Can you give me structural calculations?
No. We point out what can be seen, like sagging or deflection, but we are not structural engineers and don’t carry out calculations. Where an engineer is needed, we say so in the report.

When you need someone else
In fairness, a roof survey has limits:
- Whether the deck or joists are strong enough
- A fixed date for when the roof will need replacing
- Whether old sheeting or boards contain asbestos
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 before you book. The full list of what we check.

Tips that help
A few practical points come up again and again on our surveys. They’re worth knowing whatever the roof:
- Keep records of when the roof was laid and what work has been done
- Check from a window for ponding after heavy rain
- Check the outlets after the leaves fall
- Limit foot traffic on the covering
If you are buying, the report gives you something specific to take back to the seller or agent. You might ask for work to be done before completion, or discuss the price, depending on the findings.
Keep foot traffic on a flat roof to a minimum. Where someone does need access, ask them to use boards or a protected route, and to keep well clear of rooflights and fragile sheeting.
