Common questions in Seven Sisters
Will parking be an issue for a roof survey in Seven Sisters?
Normally it’s manageable with a little notice. Let us know the parking rules on your street and we will work around them.
Can you fly a drone over a roof in Seven Sisters?
It depends on the exact address and the weather on the day. Across London there are restriction zones around Heathrow, London City and London Heliport, plus restricted areas over Hyde Park, the City of London and the Isle of Dogs. Every London address is checked against them before a flight. Every flight is checked against the Drone Safety Map first, including zones around airports and prisons. The flight also waits for calm, dry weather, and the rest of the survey doesn’t depend on the drone.
What does a thermal roof survey show?
The images show how warm or cool each part of the surface is. Unusual patterns can point to trapped water, gaps in insulation or heat escaping, which we then check with moisture readings.
How long will you be at the property?
Expect it to take between one and two hours for most homes, plus time to check any thermal findings with moisture readings. You will then get the report by email, on the timescale of your package.
What happens after the survey?
You’ll get the report by email, with photographs and clear recommendations. The Standard Survey includes a follow-up consultation, and the Premium Survey an in-person consultation.
Can thermal imaging show missing insulation?
It can show temperature patterns that point to missing or thin insulation. It shows most clearly when it is warm inside and cold outside. We look from the loft as well, where there is safe access.
Which days do you carry out surveys?
Surveys can be booked for any day of the week: Monday to Friday, Saturdays and Sundays. Just let us know the days that suit you.
About our thermal roof survey in Seven Sisters
Wet insulation under a flat roof covering holds heat for longer than dry. That means a wet area can show up as a different temperature from the rest of the roof. It helps us see how far water may have spread under the covering, which is hard to judge by eye. We then check those areas with moisture readings. We survey ceilings below the roof, commercial roofs and pitched roof slopes, and people most frequently book us about damp patches with no obvious cause and water that travels before it shows.
Flying in London takes more checking than most places: there are flight restriction zones around Heathrow, London City and London Heliport, and restricted areas over Hyde Park, the City of London and the Isle of Dogs. Before a drone goes up in Seven Sisters, the address is checked against all of them, and where permission is needed, the flight waits for it.
We write the report in plain English, so it makes sense without any roofing background. Photographs show what each point refers to, with the urgent items made clear.

Why act early in Seven Sisters
For buyers, a thermal survey adds detail that a visual inspection cannot give. Finding hidden moisture before exchange gives you facts to raise with the seller. 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.
Prices start from £150, including VAT, for a Basic Survey. Standard is from £250 and Premium from £400. You will know the price for your survey before booking.

Checking the roof from the ground
Watch the gutters in a downpour, from a window or the ground. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry.
How it works
We will ask a few questions first, about the roof’s history, any leaks and past repairs. Then the inspection itself takes roughly 1–2 hours at a typical home, and about three to four hours for a commercial roof. Many London properties are flats or terraces with no side access, so the back of the roof is often seen from upstairs windows, from inside or, where a flight is allowed, from the air. Mention any building rules, key holders or managing agents when you book.
- First we go over the roof, the problem you’ve noticed and the conditions forecast for the visit.
- We carry out a visual inspection of the roof from wherever it can safely be seen.
- Thermal images are taken to show differences in surface temperature.
- We check the patterns that stand out with moisture readings where there’s safe access.
- The report sets out the images, what they suggest and what we recommend.
How to prepare
- If the roof is shared, arrange access with whoever manages the building
- Mention any parking restrictions on your street
- If it isn’t your property yet, arrange access through the agent

Advice
Different roofs, different checks
Pitched slate and tile roofs
Even on pitched roofs, the camera can point to heat loss and some damp. We explain what can and cannot be read from them.
Loft insulation
Insulation often gets moved during work in the loft. The camera can show where it no longer covers the ceiling.
What a survey costs
We confirm the price for your survey before booking. These are the things that affect it:
- Whether it is a home or a commercial building
- How many separate roofs there are, such as extensions, dormers and garages
- The shape of the roof and its details
- Height and safe access
Simple, low roofs take less time to survey than tall or complicated ones, and the package matters as well. We will give you the figure before anything is booked.
Getting in touch
You do not need to know any roofing terms. Just let us know:
- The type of building and roof, such as pitched or flat
- Where any leaks, stains or damp patches show inside
- Whether there is a loft hatch, a shared roof or tricky access
- When you need the report by
Booking is simple: just call 07833 053749 or send us an email, let us know about the property and we’ll suggest the right survey. We confirm the price before anything is booked.
What a thermal roof survey looks like in Seven Sisters
Historic houses like Bruce Castle, about 1.2 miles north, show how far back building in the area around Seven Sisters goes. If your home is one of the older ones, expect a mix of original materials and later repairs on the roof. 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. Older coverings on steep or tall roofs are hard to judge from below, so close-up close-up aerial shots and thermal images help.
Anyone responsible for a site like Earlsmead Primary School will know that a view from above covers a wide roof far faster than walking it. Parking in Seven Sisters, as in most of London, takes a little planning: let us know about permits, visitor bays or off-street space when you book. For businesses in and around places like The Mall Wood Green, large commercial roofs are frequently easiest to see from the air or with a thermal camera.
