St Stephens Thermal Roof Survey
Thermal roof surveys around St Stephens, with findings in writing and pictures to back them up. Weekday and weekend visits available.
- Water that travels before it shows
- Heat escaping through the roof
- Missing or slipped insulation
Tips from our surveys
There’s plenty you can do without going near the roof. Here’s what helps most:
- File the images with your roof records
- Keep dated photos of any marks on ceilings
- Tell us where and when you’ve seen damp or stains
- Remember the conditions on the day affect the results
After the visit, we put the thermal images, photos and moisture readings into one report. Each image is explained in plain words, with our recommendations. Premium reports are sent the same day.
Deal with small splits and lifted seams promptly. Once water gets under a membrane, it can travel far before it appears inside.
Thermal roof surveys for homes and businesses in St Stephens
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 can’t typically tell from the surface. We then check those areas with moisture readings. We survey insulated roof spaces, loft conversions and commercial roofs, and people most often book us about cold areas below the roof and gaps in loft insulation.
In smaller places like St Stephens, many homes are bungalows and houses with roofs you can partly see from ground level. Chimney tops, valleys and rear slopes are where close-up or thermal images help most. The forecast decides the day, as calm, dry conditions suit both. Even so, a close-up image frequently shows wear on ridges and flashings that a view from ground level misses.
Findings are set out part by part, from the coverings down to the gutters, each with a short note and a photograph. You will see the good as well as the bad.

Common questions in St Stephens
Does a conservation area affect roof work in St Stephens?
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.
Is St Stephens within the area you cover?
Yes, St Stephens is on our map. Villages and rural addresses get the same survey as a town house.
Do you survey roofs on blocks of flats?
Yes, once access has been agreed. Roofs over flats are often shared, so we need permission from the building owner or managing agent. We inspect only the parts we’re allowed to reach.
Do you test for asbestos?
No. We can flag materials that might contain asbestos, but confirming it is a job for a specialist asbestos surveyor. Buildings built or refurbished before 2000 may contain it.
What happens next?
You’ll get the report by email, with photographs and clear recommendations. The Standard Survey includes a follow-up consultation, and the Premium Survey an in-person consultation, so you can talk the findings through.
How experienced are you?
We have been surveying roofs for over 20 years and have completed over 5,000 surveys across London and South East England.
What will the report tell me?
It explains what we saw, what it means and what we’d suggest, with photos throughout. Anything we couldn’t see safely is noted too, so you know exactly what was covered.
How the survey changes by roof type
Single-ply and EPDM roofs
Many single-ply and EPDM roofs sit on insulation boards. If water gets under them, thermal imaging can suggest which boards are wet.
Parapets, valleys and junctions
Water often gets in where roofs meet walls, parapets or valley gutters. The camera can help show damp around these junctions.
Prices for thermal roof surveys in St Stephens
A few things affect what a survey costs:
- How tall the building is and how easy the roof is to see
- Features like valleys, chimneys, dormers and parapets
- Extra roofs, like extensions, dormers or garages
- Basic, Standard or Premium
Prices start from £400, including VAT. What you pay depends on how big and how high the roof is, how it can safely be seen and which survey you book.
Getting in touch
Before you get in touch, it helps to have:
- Anything about access we should know
- Photos of the roof, taken safely from the ground or a window
- The style of property, from a terrace to a block
- The property’s address and postcode
Most bookings start with a short call: ring 07833 053749 or use the contact form, and we’ll ask about the building and what you need. You will have a price before anything is arranged.

Common roof problems in St Stephens
Cold rooms under a roof, or high heating bills, lead some people to ask about heat loss. Missing or slipped insulation can stand out as temperature differences, particularly when there’s a clear difference between inside and outside.
People normally book a survey when they’ve noticed something like this:
- Water getting in at parapets and stacks
- Water that travels before it shows
- Wet areas near outlets and upstands
- Areas of a flat roof that may hold water
For hotels and guest houses around St Stephens, a roof problem found early is far less disruptive than one found by a guest, so it is worth knowing the roof’s condition.
Questions to ask before you book
- Their drone registration, if they fly one
- Whether the loft is part of the inspection
- What happens after the report arrives
- How long the report takes to arrive
Airspace, weather and St Stephens roofs
Historic houses such as Batchwood Hall, about 1.7 miles north, show how far back building in the area around St Stephens goes. If your house is among the older ones, expect a mix of original materials and later repairs on the roof, and a listed home or one in a conservation area may need consent for changes of material. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates, and flat-roofed additions turn up almost everywhere. Many roofs like these can’t be judged properly from the pavement, and that’s where a view from above or a thermal image earns its place.
If you live in an older home near St. Stephen's Church, thin or patchy insulation under an old roof often shows up clearly on a thermal image. For site and facilities teams at buildings such as Marlborough Science Academy, a drone or thermal camera can show a large roof in a single visit.

What happens on the day
The visit usually starts outside and finishes in the loft: first the slopes, edges and gutters from every safe viewpoint, then the roof space where it can be reached. All told, expect about one to two hours at a typical home, with bigger or more complicated roofs taking longer. Parking around St Stephens is usually easier than in a town centre, but mention lanes, gates or long drives. Low roofs on bungalows can often be seen well from ground level, and the loft shows the rest.
- We start with the roof, its history and any signs of damp or heat loss.
- The weather and surface conditions are recorded.
- We inspect the roof and take thermal images during the same visit.
- We back up the thermal patterns with moisture readings.
- You get the report the same day, with an in-person consultation to follow.
Before the survey
- Gather any invoices or paperwork from past roof work
- Note where any stains or damp appear
- Agree roof access with the managing agent if it’s shared
