Thermal roof survey in Hay Street
We present each thermal image next to a normal photo of the same area, making it clear where on the roof each pattern is. Each one comes with an explanation, the moisture readings and our recommendation. With a Premium Survey, the report reaches you the same day. You can talk the findings through with us at the in-person consultation. There is a 12-month follow-up as well. We survey pitched roof slopes, insulated roof spaces and flat roofs, and common reasons people get in touch are cold spots on ceilings under the roof and patches of heat loss across the roof.
Villages like Hay Street often stand in open country, where wind can be strong. A small drone cannot fly safely in strong wind or heavy rain, and thermal imaging works best with little wind. We plan the journey, access and timing around the weather. If the day turns windy or wet, the visit can be moved.
Nothing in the report is left vague: if work is needed, the report says so clearly.

How we price thermal roof surveys
Every roof is different, so prices are confirmed before booking. These are the things that affect it:
- The type of building, from a house to a block or an office
- The package you choose: Basic, Standard or Premium
- The height of the building and how the roof can be seen safely
- Extra roofs, like extensions, dormers or garages
Our price is from £400, including VAT. What you pay depends on the size and height of the roof, access and which survey you book.
What we need to know
Here’s what helps us most when you get in touch:
- Dates you’re working to, such as exchange
- How the loft is reached, if there is one
- The property’s address and postcode
- The kind of building and roof involved
Once you know what you need, phone 07833 053749 or email us. We will suggest a package, agree the price and find a date, weekday or weekend.

What happens on the day
Safety comes first on every visit. Everything that can be seen safely is inspected, and anything we can’t see is noted in the report. The survey normally takes about one to two hours at a house, including the thermal images, and around 3–4 hours for a commercial roof. Somewhere as small as Hay Street, access is often the only tricky part. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Weekday and weekend visits are available.
- We start with the roof, its history and any signs of damp or heat loss.
- We check the conditions and note how they may affect the images.
- We inspect the roof and take thermal images during the same visit.
- Moisture readings are used to check what the camera shows.
- You get the report the same day, with an in-person consultation to follow.
Preparing for the visit
- Mention any parking restrictions on your street
- For flats, make sure roof access has been agreed
- Leave a clear route to the loft
Booking a survey
You can call us seven days a week. To book or ask a question, phone 07833 053749 or send us an email.
Advice
Tips from our surveys
Getting the most from a thermal roof survey starts before we arrive and carries on afterwards. Tips:
- Tell us where and when you’ve seen damp or stains
- Check from the ground or a window, never by climbing
- Remember the conditions on the day affect the results
- Keep dated photos of any marks on ceilings
After the visit, we put the thermal images, photos and moisture readings into one report. We explain what each image may mean, alongside what we recommend. Premium reports are sent the same day.
Deal with small splits and lifted seams promptly. Water that gets under a covering can spread a long way before it shows.
When to book a survey in Hay Street
People frequently book a thermal survey when a damp patch has no obvious cause. A leak may start well away from where the stain appears. The camera helps narrow the search.
Look out for signs like these:
- Wet areas near outlets and upstands
- Leaks far from where the stain appears
- Areas losing heat at the eaves and junctions
- Damp around chimneys and parapets
If you look after a building such as Jenyns First School and Nursery, thermal images can show where wet insulation sits under a big flat roof.
What to check before booking
- Their track record with similar roofs
- Will they check the loft as well as the outside?
- Whether VAT is in the quoted price
- How they plan to inspect the roof safely
Rented homes, blocks and businesses
Freeholders and residents’ companies use a roof report to plan and budget, putting the urgent items at the top.
If the property is let, the agent or a tenant can let us in. Surveys run seven days a week, which can make access easier.
Honest limits
Every survey has limits, and it’s better to know them up front. Keep these in mind:
- Insulation values or heat loss calculations
- Readings unaffected by sun, shade or reflections
- The condition of timbers we cannot see

Your questions about thermal roof surveys in Hay Street
How do I find out if my home in Hay Street is listed?
We can’t confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case, and councils can also use Article 4 directions.
Do you cover smaller places like Hay Street?
Yes, Hay Street is on our map. Villages and rural addresses get the same survey as a town house, with the route planned beforehand.
Do I have to be there for the survey?
If the survey includes the loft or the inside of the building, someone needs to let us in. We will talk about access as you book.
What happens next?
You receive the written report by email, with photographs and recommendations. It is yours to share with a seller, insurer, roofer or managing agent, whichever applies.
Do you carry professional indemnity insurance?
We are covered by professional indemnity and public liability insurance, for every survey we carry out.
Is it the same as a RICS Level 2 or Level 3 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, so it sits alongside a building survey rather than replacing it.
Does the report include photos?
Yes. We photograph the roof as we go, and they go into the written report.
Airspace, weather and Hay Street roofs
Much Hadham Palace, about 4.7 miles south-east, is one of the historic houses in the wider area around Hay Street. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and a listed home or one in a conservation area may need consent for changes of material. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile, and flat-roofed additions turn up almost everywhere. Steep or complicated roofs are frequently hard to see from ground level, which is where aerial photos and thermal images help.
If you live in an older home near Parish Church of St Mary the Virgin, thin or patchy insulation under an old roof frequently shows up clearly on a thermal image.
