Questions from Bell Green
Does a conservation area affect roof work in Bell Green?
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.
Can you fly a drone over a roof in Bell Green?
Typically it comes down to two things: the airspace at the address and the weather. London’s airspace includes flight restriction zones around Heathrow, London City Airport and London Heliport, and restricted areas over Hyde Park, the City of London and the Isle of Dogs. Each address is checked against all of them before the drone goes up. Before any flight, we check the Drone Safety Map for airspace restrictions. High wind or heavy rain also stops a small drone flying, and the rest of the survey does not depend on the drone.
Will the survey show heat loss through my roof?
The camera can point to heat loss and gaps in insulation. We don’t give energy ratings or heat loss calculations, but the images show where improvements may help.
Does this replace a RICS home survey?
No. Our survey is a roof survey, not a RICS Level 2 or Level 3 survey of the whole building. It focuses on the roof and can sit alongside a RICS survey.
Do I have to be there for the survey?
It depends on what we need to see. For inside areas and the roof space, someone has to give us access.
Which days do you carry out surveys?
We survey on any day from Monday to Sunday, during the day. Let us know your preferred days as you book.
Do you test for asbestos?
No. We do not sample or test for asbestos. The report may flag materials that could contain asbestos on buildings built or refurbished before 2000.
Thermal roof surveys for homes and businesses in Bell Green
A thermal camera can help when the cause of damp is not obvious. Water can travel some distance under a roof covering before it shows inside, and temperature patterns can help us trace where it may have come from. The images are used alongside a visual inspection and moisture readings, so the findings don’t rely on the camera alone. Common reasons to book are wet insulation beneath the membrane and water getting in at parapets and stacks, across loft conversions, pitched roof slopes and flat roofs.
London’s roofs are frequently hard to see from the street: butterfly roofs behind parapets, dormer tops and flat roofs over back additions. That’s where a view from the air or a thermal camera helps, by showing what can’t be reached safely. The weather decides the day: both drones and thermal cameras need the right conditions. Thermal images show surface temperature, not water itself, so findings are checked with moisture readings.
The Standard Survey adds moisture detection, a structural check and a follow-up consultation. The Premium Survey goes further, with thermal imaging, drone inspection where applicable, structural analysis and an in-person consultation.

Roof by roof
GRP fibreglass roofs
GRP roofs are laid over timber boards, so trapped moisture can affect the deck. The camera can help show where to look.
Pitched slate and tile roofs
Slate and tile roofs are frequently harder to read with a thermal camera, because of the air space beneath. We back up what the camera shows with a look in the loft where we can.
How it works
Photos are taken throughout the visit, so you can see in the report what we found and where. Close-ups come from the safest viewpoint available, including by drone where it is applicable and the weather allows. Most surveys take roughly 1–2 hours at a typical home; commercial roofs usually need 3–4 hours. In converted houses and mansion blocks, the loft hatch is frequently on a shared landing. 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 go through the roof, the problem and the weather expected on the day.
- The roof is inspected visually from safe positions.
- We take thermal images of the roof and of the loft where we can reach it.
- We take moisture readings where the images suggest a problem.
- Each image is set beside a normal photo and explained in the report.
How to prepare
- Buyers: confirm access with the estate agent or seller
- If the roof is shared, arrange access with whoever manages the building
- Leave side gates unlocked
Book a survey
Getting a price is simple: just phone 07833 053749 or send us an email, let us know about the property and we will explain which survey suits. We confirm the price before anything is booked.
Advice
What affects the price in Bell Green
What a survey costs depends on the time and equipment it needs. The main factors are:
- The package you choose: Basic, Standard or Premium
- If the survey needs thermal imaging or a drone
- Extensions, dormers and garages with roofs of their own
- The roof’s overall size
Price depends partly on the package: Basic from £150, Standard from £250 or Premium from £400, all including VAT. The roof’s size, height and access matter as well.
Booking your survey
There’s no need for technical words. Just let us know:
- What’s prompted the survey
- Any photos you have, taken from the ground or a window
- Your timetable, like an exchange date
- The address and postcode of the property
We confirm the price for your survey before booking, so you know the cost up front. Prices start from £400, including VAT. For a price for your roof, call 07833 053749 or email us.

Rented homes, blocks and businesses
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 with less disruption.
For blocks of flats, a roof survey helps managing agents and residents’ management companies plan ahead. Recommendations are set out with the most urgent first where relevant, which helps with budgets and planning.
When to book a survey in Bell Green
On big commercial and residential flat roofs, thermal imaging helps owners plan. It can suggest which areas may be wet and which seem dry, so we know where to take moisture readings.
Common reasons to book include:
- Ceilings that feel colder in places
- Leaks far from where the stain appears
- Areas of a flat roof that may hold water
- Damp around chimneys and parapets
With Kingswood House about 2.1 miles west, the area around Bell Green has a long history. Aerial photos and thermal images let an old roof be checked without anyone disturbing it.
Before booking anyone
- Are they insured for the work?
- How much experience they have with roofs like yours
- Will they check the loft as well as the outside?
- Their drone registration, if they fly one
Tips from our surveys
A little preparation and a few simple habits help, both for the survey and for the roof itself. Some pointers:
- File the images with your roof records
- Make sure the loft can be reached safely
- Don’t climb onto the roof to look for leaks yourself
- Take photos of stains as they appear, so we can compare
Once we’ve been, the thermal images, photos and readings go into a single report. We explain what each image may mean, alongside what we recommend. With a Premium Survey, you get the report the same day.
Check that loft insulation is laid evenly and hasn’t been pushed aside. Insulation is often moved when people work in the roof space.
Airspace, weather and Bell Green roofs
If the drone is used for your survey, the flight is checked against the Drone Safety Map first. Welsh slate on Victorian and Edwardian terraces is a familiar sight across inner London. A butterfly roof with a central valley gutter, tucked behind a parapet wall, is common on these houses. Shared chimney stacks, party-wall upstands and lead work come with this kind of house. Many roofs like these cannot be judged properly from the pavement, and that is where a view from above or a thermal image earns its place.
If your home is one of the older ones in the streets near St Michael's and All Angels, older roofs can be steep and hard to see from the street, which is where close-up aerial shots and thermal images help. For site and facilities teams at buildings such as Haseltine Primary School, thermal images can show where wet insulation sits under a big flat roof.
