Find out what’s going on with the roof before you decide what to do next. We carry out thermal roof surveys in Monkswood.
- Water getting in at parapets and stacks
- Damp patches with no obvious cause

FAQs for Monkswood
Do you cover smaller places like Monkswood?
Yes, we do. We work right across London and South East England, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is my home in Monkswood listed or in a conservation area?
For listing, use Historic England’s list; for conservation areas, ask the council. The answer matters most when a change of material is on the cards.
How long have you been surveying roofs?
More than 5,000 surveys over 20+ years, across London and South East England.
How long is the visit?
Time on site depends on the roof; most visits take about 1–2 hours at most homes, and more on a big or complicated roof. The written report follows by email.
Is thermal imaging useful on pitched roofs?
On pitched roofs, the camera can point to heat loss and some damp patterns. We explain what the images can and cannot tell you, and back them up with a visual inspection and moisture readings.
Do you climb onto every roof?
Only if it’s safe. We check everything that can safely be seen: from ground level, from windows and vantage points, from the loft space, from the roof itself where safe and by drone where it applies. Anything we cannot see is noted in the report.
Can you give me structural calculations?
No. We’re experienced roof surveyors, and visible signs such as sagging are noted, but calculations and an engineer’s opinion are outside what we do. The report will say if you need an engineer.
Thermal roof survey in Monkswood: what you get
Our thermal survey records how the surface temperature varies across your roof. The patterns can suggest wet insulation, gaps in insulation or places where heat is getting out. The camera doesn’t see water itself, so findings are checked with moisture readings. It comes as part of our Premium Survey, from £400. Conditions on the day affect the results, and the report explains how. If you are worried about patches of heat loss across the roof and missing or slipped insulation, we can find out what’s behind it, whatever the roof.
Some older homes in villages like Monkswood are listed or in a conservation area. A look from the air or with a thermal camera doesn’t touch the roof, which suits a building where any change needs care. Check with the council before planning any work on a listed building or one in a conservation area.
Where we cannot see part of the roof, the report says so. You will know exactly what was inspected and what wasn’t, and what we’d suggest next.

Before and after the survey
You do not need to be a roofer to help. Here’s what helps most:
- Keep a record of when stains appear
- Do not climb onto the roof to look for leaks yourself
- Check outlets after heavy rain
- Use the report as a baseline for later checks
Where a pattern can’t be confirmed, the report says what could help, for instance electronic leak detection or a roofer opening up a small section.
Watch for new damp patches on ceilings beneath the roof. Early action keeps insulation from staying wet.
What a thermal roof survey looks like in Monkswood
Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles. Where a roof is steep, tall or hard to see from the ground, drone photos and thermal images add detail. Where the drone is part of the survey, we check the Drone Safety Map for restrictions before flying.
Anyone responsible for a site like Homerswood Primary and Nursery School will know that big roofs are where close-up aerial shots and thermal images show the most at once. Digswell House lies about 0.1 miles south-west, so building around Monkswood goes back a long way. Older roofs nearby can be steep and hard to see from ground level, and a survey from above or with a thermal imager doesn’t touch the roof itself. The streets around a church such as The Parish Church of St John are often among the oldest in a place, and if your home is one of the older ones nearby, tall stacks and steep slopes are easier to judge with close-up aerial photos than from the pavement.

How the survey works
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 typically takes about one to two hours for most houses; commercial roofs usually need 3–4 hours. In a hamlet or village like Monkswood, a postcode does not always lead to the right gate, so a few directions are welcome. After that, the survey runs as it would anywhere.
- We start by discussing the roof, any signs of damp and how the weather may affect the images.
- We carry out a visual inspection of the roof from wherever it can be seen safely.
- Thermal images are taken to show differences in surface temperature.
- Any patterns of interest are checked with moisture readings where we can reach them.
- We write up the thermal images alongside ordinary photos and recommendations.
Before we arrive
- Leave a clear route to the loft
- If the roof is shared, arrange access with whoever manages the building
- Point out any leaks or damp patches

When you need someone else
Before booking, it’s worth knowing what a survey will not do:
- A formal energy assessment
- What’s inside walls or under coverings, without opening up
- Whether the deck or roof structure is strong enough

Roofs we survey in Monkswood
- Ceilings below the roof
- Insulated roof spaces
- Commercial roofs
- Loft conversions
- Flat roofs
- Pitched roof slopes
Why get it checked now?
Once insulation under a membrane is wet, it tends to stay wet. Over time, it insulates less well and can harm the deck. Finding them early can mean a smaller job. In a place like Monkswood, a barn or garage roof left to fail puts whatever is inside at risk. It is worth including them in a survey before a winter does the damage.
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how it can be reached and seen safely. Thermal roof survey starts from £400, including VAT.

Checking the roof from the ground
A DIY look is useful, but it isn’t a survey. You won’t see flashings, valleys or the backs of chimneys properly from the ground.
Look up at the roof after a storm, from the ground: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Leave anything above ground level to a survey.

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 around your tenants.
