About our flat roof survey in Seven Sisters
We inspect a flat roof from wherever it can be seen safely: from the roof itself where that’s safe, from windows and nearby vantage points, and from inside where there is access. Fragile rooflights and fragile sheets are never walked on. If part of the roof can’t be seen or reached safely, the report says so, so the limits of the survey are clear. Common reasons to book are failed upstands where the roof meets a wall and water getting in at rooflights, across GRP fibreglass, mastic asphalt and felt flat roofs.
On a London roof terrace or a flat roof over a back addition, water frequently runs under the covering before it shows. Upstands against parapets, outlets and the edge where flat meets pitched are common entry points. In a converted house in Seven Sisters, the roof above may belong to the building rather than one flat.
If any part of the flat roof couldn’t be seen safely, we say so in the report. You’ll know exactly what was inspected and what wasn’t, and what we’d suggest next.

Flat and commercial roofs around Seven Sisters
Inner London’s Victorian and Edwardian terraces often have Welsh slate roofs. Behind many of their parapets sit butterfly roofs and valley gutters that can’t be seen from the pavement. 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. Bruce Castle, about 1.2 miles north, is one of the historic houses in the wider area around Seven Sisters. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years.
If you own a rental within reach of Seven Sisters station, flat roofs on let property tend to be checked only when they fail, which is the costly way round. Take a building like Earlsmead Primary School: large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

How it works
We look at the roof from outside and, where it’s relevant and there’s safe access, from inside the roof space too. In the loft, the signs we look for are staining, damp, daylight and sagging, as far as the space allows. The whole visit usually takes an hour or two on an ordinary house, with bigger or more complicated roofs taking longer. Surveys in Seven Sisters can be booked for any day of the week. London parking is frequently by permit or pay-and-display, so it is useful to know what’s near you, and to clear a path to the loft hatch. Upstairs rooms at the back are useful too, as they frequently give the best view of a rear addition.
- First you give us the address, what the roof covers and any leaks you’ve noticed.
- The roof is inspected from safe viewpoints, and from the roof itself where that’s safe.
- The covering, falls, upstands, outlets, edge trims and rooflights are checked and photographed.
- We check the rooms or spaces under the roof for staining where we can reach them.
- You get a written report with photos and our recommendations.
Preparing for the visit
- Find any records of previous roof work
- For a flat or shared roof, check access with whoever owns or manages the building
- Leave side gates unlocked

Different roofs, different checks
EPDM rubber
EPDM frequently lasts 30 to 50 years, but it relies on its seams, trims and upstands being well finished. Those details are where we focus.
Mastic asphalt
With age, asphalt can harden and crack with movement. The report shows where it is cracking and how far it seems to extend.
Common roof problems in Seven Sisters
Every flat roof covering has a working life. Around 15 to 20 years is common for felt, while EPDM often lasts 30 to 50 years and GRP up to about 30, though workmanship and upkeep make a big difference. We can tell you how your roof is doing, whatever its age.
People typically book a survey when they’ve noticed something like this:
- Pools of water lying on the roof
- Dips that suggest the deck is deflecting
- Edge trims that have lifted or split
- Splits, cracks and crazing
If you live in an older home near Church of Holy Trinity, flat-roofed rear additions and dormers added over the years are worth checking.
Choosing a roof surveyor
- Whether VAT is added on top
- What follow-up you get after the report
- Whether any drone flown is registered with the CAA

FAQs for Seven Sisters
Does a conservation area affect roof work in Seven Sisters?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it’s worth checking before planning any.
Is parking a problem for a survey in Seven Sisters?
Normally it is manageable with a little notice. Let us know what parking is available nearby, and the visit is planned around it.

The quickest way is to phone 07833 053749 or send us an email. Let us know the address and a little about the roof. We survey on weekdays, Saturdays and Sundays.
Can you survey a shared roof?
Yes. A shared roof needs access agreed first. Mention it when you get in touch and we’ll explain what’s needed.
Will the survey show why my flat roof is leaking?
The survey covers the covering and all the details where leaks usually begin, recording anything that could let water through. If the source is hidden, we may suggest a leak investigation or electronic leak detection.
What’s in the survey report?
It works through the roof part by part, in writing and with photos. The most urgent items are made clear.
Can you give me structural calculations?
No. Visible signs like deflection or sagging are recorded, but calculations and an engineer’s opinion are outside what we do. If one is needed, the report says so.
