Thermal Roof Survey in Dollis Hill
We take a careful look at the roof at your property in Dollis Hill, with photographs and a written report.
- Stains that keep coming back
- Missing or slipped insulation
- Wet insulation beneath the membrane
What you can safely check yourself
Look up at the roof after a storm, from the ground: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Do not go up yourself.
If you have a loft with safe access, take a look inside. Take a torch and only step on boards or joists, and look for staining, damp timber or daylight coming through.
Thermal roof surveys for homes and businesses in Dollis Hill
On a flat roof, wet insulation holds heat longer than dry insulation. 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, something you cannot normally tell from the surface. We then check those areas with moisture readings. If you’ve noticed heat escaping through the roof and damp around roof outlets and upstands, we can find out what’s behind it.
London airspace is busy and tightly controlled: restriction zones surround Heathrow, London City Airport and London Heliport, and Hyde Park, the City of London and the Isle of Dogs have restricted areas of their own. Every address in Dollis Hill is checked before any drone flight, and where permission is needed, the flight waits for it.
Pictures do a lot of the work in our reports, because a photo of a cracked flashing says more than a paragraph. If something couldn’t be seen safely, the report is clear about it.

Tips from our surveys
A little preparation and a few simple habits help. Some pointers:
- Keep outlets and gutters clear to stop water sitting
- Don’t climb onto the roof to look for leaks yourself
- Use the report as a baseline for later checks
- Note where damp appears and after what weather
Buyers can use the findings when talking to the seller or agent. It is your decision how to use it, whether that is asking for work or discussing the price.
Keep an eye on ceilings under the roof for new stains. Early action keeps insulation from staying wet.
When you need someone else
Some things cannot be seen without opening up the roof, so a survey has limits:
- The condition of timbers we can’t see
- Clear results when the conditions on the day are poor
- Insulation values or heat loss calculations
If in doubt, phone 07833 053749 or send us an email and we will suggest the right survey. What a survey covers and does not.

Prices for thermal roof surveys in Dollis Hill
The price reflects the time and kit the roof needs. That comes down to:
- Chimneys, valleys, parapets and other details
- Building height and the viewpoints available
- Commercial roofs and larger buildings
- The number of roofs, including extensions and garages
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. The price is confirmed before you book.
Booking your survey
To price your survey accurately, we will ask about:
- Any photos you have, taken from the ground or a window
- Your timetable, such as an exchange date
- The property’s address and postcode
- Why you want a survey: buying, a leak, a storm or new work
You can call us seven days a week, including Saturdays and Sundays. For a price or to book, call 07833 053749 or use the contact form.

Flying and imaging in Dollis Hill
Where the drone is part of the survey, the flight is checked against the Drone Safety Map first. Further from the centre, London’s housing takes in interwar semis with hipped roofs in clay or concrete tiles as well as slate-roofed terraces. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. A drone or thermal camera adds most on the steep, tall and hidden parts of roofs like these.
For hotels and guest houses around Dollis Hill, a roof problem found early is far less disruptive than one found by a guest, so it is worth knowing the roof’s condition. For site and facilities teams at buildings such as Our Lady of Grace Catholic Junior School, a view from above covers a wide roof far faster than walking it.

The survey, step by step
A survey visit follows a simple order: we listen to what’s been worrying you, look at the roof from every safe viewpoint, take photographs as we go and make notes for the report. Most visits take between one and two hours at a typical home; commercial roofs usually need 3–4 hours. In a London conversion, the way into the loft space is frequently from a communal landing or the top flat. Where that’s the case, access needs agreeing with whoever controls that landing. Everything else is planned around the building, not the postcode.
- You let us know about the roof and any damp, leaks or cold rooms.
- The weather and surface conditions are recorded.
- We inspect the roof and take thermal images during the same visit.
- Moisture readings are used to check what the camera shows.
- The Premium report reaches you the same day, and we go through it with you in person.
Preparing for the visit
- If the roof is shared, arrange access with whoever manages the building
- Have any paperwork from past roof work to hand
- Let us know about parking near the property
Arrange a survey
Getting a price is simple: just phone 07833 053749 or use the contact form, let us know about the property and we will point you to the right survey. The price is agreed up front.
Advice
Common questions in Dollis Hill
Is parking a problem for a survey in Dollis Hill?
Sometimes, yes. Where there are permit zones, a visitor permit or nearby pay-and-display bay works well.
How do I find out if my home in Dollis Hill is listed?
We cannot confirm that for you, but Historic England’s list and your council can. Both listing and conservation areas can limit changes of roofing material, and councils can also use Article 4 directions.
When does the report arrive?
It depends on the package: the Basic Survey report arrives within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey the same day. Reports are sent by email.
Do you take photos of the roof?
Yes. The report includes photographs of what we found.
Do you survey roofs on blocks of flats?
Yes. Shared roofs just need a little more planning. Tell us about it when booking and we’ll plan the survey around it.
What will the report tell me?
It sets out what we found, why it matters and what we recommend, with photos throughout. It also says if any part of the roof couldn’t be seen safely.
What conditions are best for thermal imaging?
The results depend on the weather. Dry, calm weather after some sun gives the best chance of clear images. Our report notes the conditions and how they affected the findings.
Signs you need a thermal roof survey in Dollis Hill
After a long-running leak, insulation under a flat roof can stay wet. Knowing how much of the roof is affected helps decide between a local repair and more. A thermal survey, checked with moisture readings, can give a much clearer picture.
Things that often lead to a survey include:
- Leaks that are hard to trace
- Damp around roof outlets and upstands
- Gaps in loft insulation
- Damp that repairs haven’t cured
Controlled parking zones are common in London, so mention any permit rules for Dollis Hill.
Before you book anyone
