Coldharbour questions
Will parking be an issue for a roof survey in Coldharbour?
Sometimes, yes. If Coldharbour has controlled parking where you are, a visitor permit is the easiest answer.
Is my home in Coldharbour listed or in a conservation area?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. It matters most if you are planning to re-roof in a different material.
Can you give me structural calculations?
No. Our survey isn’t a structural engineer’s report. If we see signs that need an engineer’s opinion, we will recommend one.
Can thermal imaging show missing insulation?
Gaps and thin areas of insulation can show up on the camera. The difference is clearest when the building is heated and it’s colder outside. Where we can reach the loft safely, we check there too.
What will the report tell me?
A photo-illustrated written report, explaining the condition of the roof, any defects and our recommendations. The Standard Survey adds moisture detection and a structural check, and the Premium Survey adds thermal imaging, drone inspection where applicable and structural analysis.
Will thermal imaging find my leak?
Thermal imaging can help, alongside other checks. What it shows depends on the weather and the roof. Where it can’t be pinned down, the report suggests a next step, like electronic leak detection.
Do I need to be at home?
Not always. If we only need the outside, we can agree that beforehand, but anything inside needs someone there to give access.
Thermal roof surveys for homes and businesses in Coldharbour
A thermal survey can point to places where heat is escaping through the roof. Gaps in loft insulation and poorly insulated areas can stand out on the images. It works best when the building is heated and it is colder outside. Our report points out what the images suggest and where to look more closely. We don’t give energy ratings or heat loss calculations. We are often asked to look into leaks that are hard to trace and stains that keep coming back, on flat roofs, loft conversions and commercial roofs.
London airspace is busy and tightly controlled: 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. Every address in Coldharbour is checked before any drone flight, and where permission is needed, the flight waits for it.
After the visit, you get a written report with photos, emailed to you. It explains the condition of the roof, the defects we found and what we recommend.

Rented homes, blocks and businesses
Shared roofs need a little more planning: access has to be agreed with whoever owns or manages the building. Mention it when you contact us and we will plan the survey around it.
A roof problem in a let property affects your tenants as well as the building. A survey shows what needs attention, so you can plan the work.
Can I check my roof myself?
Watch the gutters in a downpour, from a window or the ground. Water spilling over the edge can point to a blockage or a sagging run.
A lot can be seen from the ground. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Never climb onto the roof to look.
What happens if roof problems are left?
The longer moisture sits in a roof, the more it can affect timbers and finishes below. Surveying sooner gives you more choice about what to do. A hidden valley or parapet gutter on a London house can hold water for weeks before anyone notices. When the stain finally shows, the damage underneath is frequently older than it looks.
Simple, low roofs take less time to survey than tall or complicated ones, and the package you pick makes a difference too. The price is always agreed first.

The survey, step by step
After the inspection, everything we found is written up as a photo-illustrated written report, sent to you by email. As for time on site, it normally takes roughly 1–2 hours at a house, including the thermal images, and around 3–4 hours for a commercial roof. London terraces rarely offer a view of the whole roof from one spot, so in Coldharbour we work round the house, using the street, the windows, the loft and any safe vantage point behind it. Shared stairs or a basement flat? Tell us who holds the keys.
- 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.
- The report pairs each thermal image with a photo and explains what it suggests.
Before we arrive
- Keep pets in another room
- Have any paperwork from past roof work to hand
- Leave side gates unlocked

Controlled parking zones are common in London, so mention any permit rules for Coldharbour. The streets around a church like St Alban are often among the oldest in a place, and if yours is one of the older homes nearby, steep roofs, tall chimneys and hidden valleys can be hard to see from ground level, and that is where a view by drone or thermal camera helps. If you look after a building such as Mottingham Primary School, thermal images can show where wet insulation sits under a big flat roof.

How we price thermal roof surveys
The price reflects the time and kit the roof needs. The main factors are:
- Roof area
- The package you choose: Basic, Standard or Premium
- Chimneys, valleys, parapets and other details
- If the survey needs thermal imaging or a drone
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. You will know the figure before booking.
What we need to know
We’ll normally ask about:
- What’s prompted the survey
- Where any leaks, stains or damp patches show inside
- Whether there’s a loft hatch, a shared roof or tricky access
- When you need the report by
Photos help, if you have them. Take them safely from the ground or a window, and please do not climb up for a closer look. To send them or to book, ring 07833 053749 or email us.
Different roofs, different checks
Pitched slate and tile roofs
On pitched roofs, slates and tiles over a ventilated space can mask what’s happening underneath. We back up what the camera shows with a look in the loft where we can.
Loft insulation
From inside the loft, thermal imaging can show gaps in insulation and cold spots. We look where there is safe access.
