Thermal Roof Survey in Forty Hill
Thermal imaging to find moisture and heat loss patterns in a roof around Forty Hill, with a written report you can act on. Weekday and weekend visits available.
- Moisture around outlets and upstands
- Cold areas below the roof
- Areas losing heat at the eaves and junctions
How the survey changes by roof type
Felt and asphalt flat roofs
Built-up felt and asphalt roofs can hide trapped water for a long time. The camera can give clues to where it’s sitting, given suitable conditions on the day.
Loft insulation
Insulation frequently gets moved during work in the loft. The camera can show where it no longer covers the ceiling.
Thermal roof surveys for homes and businesses in Forty Hill
Thermal imaging can also show where a roof is losing heat. Gaps in loft insulation and poorly insulated areas can stand out on the images. The difference shows most clearly when it is warm inside and cold outside. Our report points out what the images suggest and where to look more closely. We do not give energy ratings or heat loss calculations. Typical surveys look at stains that keep coming back and gaps in loft insulation, on loft conversions, pitched roof slopes and ceilings below the roof.
In London’s terraces and conversions, roofs are packed close together, so privacy and neighbours matter as much as the view. Images are taken to show the roof we are surveying, with care for neighbours’ privacy. Mention access, height and anything unusual about the building as you book. Steep slopes, tall chimneys and rear additions are where the extra view helps most.
Findings are set out part by part, from the coverings down to the gutters. It records what’s sound as well as what isn’t.

Common questions in Forty Hill
Is parking a problem for a survey in Forty Hill?
Usually it’s manageable with a little notice. Tell us what parking is available nearby, and the visit is planned around it.
How do I find out if my home in Forty Hill is listed?
Start with Historic England’s list for listing and your council for conservation areas. It is worth checking before planning roof work, as both can affect what’s allowed.
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, if whoever owns or manages the building agrees access. On a shared roof we can only inspect the parts we’re allowed to reach, and the report makes that clear.
Do you cover Forty Hill for thermal roof surveys?
Yes. Our area covers London and South East England, and that includes Forty Hill.
What’s in the report?
A photo-illustrated written report, covering the condition of the roof, the defects we found and what we recommend. The Standard Survey adds moisture detection and a structural check, and the Premium Survey adds thermal imaging, drone inspection where it applies and structural analysis.
What happens next?
You will receive the report by email, and you decide the next step: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
Useful tips for Forty Hill property owners
A survey works best with a little help from you, before and after. Some tips:
- Clear leaves from outlets and gutters each autumn
- Take photos of stains as they appear, so we can compare
- Talk to us about the weather when booking
- Move stored items away from the loft hatch
After the visit, we put the thermal images, photos and moisture readings into one report. Each image is explained in plain words, alongside what we recommend. With a Premium Survey, you get the report the same day.
Watch for new damp patches on ceilings beneath the roof. Catching a leak early stops insulation getting soaked.

Airspace, weather and Forty Hill roofs
Outer London has plenty of Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, often with hipped roofs in clay or concrete tiles. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. Steep or complicated roofs are often hard to see from the ground, which is where close-up aerial shots and thermal images help. About 0.3 miles north lies Forty Hall, a reminder of how long the area around Forty Hill has been built on. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and the council can say whether a home is in a conservation area.
If you run a business near Edmonton Green Shopping Centre, large commercial roofs are often easiest to see by drone or thermal camera. Controlled parking zones are common in London, so mention any permit rules for Forty Hill, along with any off-street space.

What affects the cost of thermal roof surveys
Survey packages start from £150, inc. VAT. The price for your roof depends on:
- Commercial roofs and larger buildings
- Extra roofs, like extensions, dormers or garages

- If the survey needs thermal imaging or a drone
The Premium Survey includes thermal imaging and drone inspection where applicable, from £400 with VAT included. We can help you choose the package that fits what you want to find out.
Booking your survey
The more you let us know, the easier it is to price the survey. When you contact us, tell us:
- Why you want a survey: buying, a leak, a storm or new work
- The kind of building and roof involved
- Pictures of the roof from a safe spot, if you have them
- The address and postcode of the property
You can call us seven days a week, including Saturdays and Sundays. For a price or to book, call 07833 053749 or send us an email.
What happens if roof problems are left?
The longer moisture sits in a roof, the more it can affect timbers and finishes below. Looking now, while the damage may still be limited, keeps more options open. Any roof job in Forty Hill means planning around parking, neighbours and access. Knowing what’s needed early gives you time to plan it calmly, rather than in a rush after a leak.
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. You will know the figure before booking.

What happens on the day
The aim of the visit is simple: to look at the roof as closely as is safe and record what we find. Notes and photographs go into the written report. The visit typically takes between one and two hours at most homes, while a commercial roof takes nearer three to four hours. In converted houses and mansion blocks, the loft hatch is frequently on a shared landing. If that applies to your building, it’s useful to agree access with the neighbours or the managing agent first. Otherwise, the visit in Forty Hill runs like any other.
- First we discuss the roof, any damp and the forecast for the visit.
- We look over the roof from wherever it is safe.
- Thermal images are taken across the roof and, where there’s safe access, in the loft.
- We take moisture readings where the images suggest a problem.
- Each image is set beside a normal photo and explained in the report.
Getting ready for the survey
- Let us know about parking before the day
- Show us where any leaks or stains appear
- For a flat or shared roof, check access with the building owner or managing agent
Arrange a survey
Booking is simple: just call 07833 053749 or use the contact form and give us a few details about the property and we’ll suggest the right survey. We confirm the price before anything is booked.
