About thermal roof surveys in Portsmouth
Thermal imaging is often most useful on flat roofs, from small extensions to large commercial roofs. Patterns can suggest where water is trapped under the covering. On pitched roofs, slates and tiles over a ventilated space can hide what’s below, so we combine the camera with an inspection from the loft where there’s safe access. We survey flat roofs, loft conversions and insulated roof spaces, and the problems we’re asked to look at most are leaks far from where the stain appears and damp around chimneys and parapets.
Where it’s relevant and can be reached safely, the loft space is checked as well as the outside. Inside, we look for staining, damp, gaps and signs of movement. All in, the survey typically takes about one to two hours at a typical home, while a commercial roof takes nearer three to four hours.
- We talk through the roof, any damp or leaks, and the weather expected on the day.
- The roof is inspected visually from safe viewpoints.
- Thermal images are taken to show differences in surface temperature.
- We check the patterns that stand out with moisture readings where there’s safe access.
- The report sets out the images, what they suggest and what we recommend.

Airspace, weather and roofs across Portsmouth
Across Portsmouth, from Southsea, Milton and Landport outwards, lots of roofs can’t be seen properly from the street. A drone or thermal camera adds a view you cannot get from ground level.
We work right across London and the South East, from the Isle of Wight to Hertfordshire, and Portsmouth is well within that. Visits run on weekdays and at weekends. Parts of Portsmouth are coastal, so the weather on the day matters more for drone flights and roof access. If conditions are not right, the visit moves to a calmer day.
Portsmouth: Take a building like Manor Infant School: thermal images can show where wet insulation sits under a big flat roof. The streets around a church like St Wilfrid are frequently among the oldest in a place, and if your house is among the older ones nearby, older roofs can be steep and hard to see from the street, which is where photos from the air and thermal images help.
Common roof problems in Portsmouth
Not every roof problem shows on the surface. Trapped moisture, missing insulation and hidden heat loss are three examples. Thermal imaging gives us another way to look for them.
Common reasons to book include:
- Leaks that are hard to trace
- Patches of heat loss across the roof
- Damp around roof outlets and upstands
- Damp patches with no obvious cause
Prices for thermal roof surveys in Portsmouth
The price reflects the time and kit the roof needs. The main factors are:
- Which survey package you book
- Whether thermal imaging or a drone is needed
- Whether it’s a home or a commercial building
- Features like valleys, chimneys, dormers and parapets
Prices start from £150, inc. VAT, for a Basic Survey. The Standard Survey starts from £250 and the Premium Survey from £400, both including VAT. You will know the exact price before booking.
Helping us price your survey
To price your survey accurately, we’ll ask about:
- Photos of the roof, taken safely from ground level or a window
- Whether there’s a loft hatch, a shared roof or tricky access
- Your postcode, so we can check access and travel
- Why you want a survey: buying, a leak, a storm or new work
Photos help, if you have them. Take them safely from ground level or a window; never climb up to get a better view. To send them or to book, phone 07833 053749 or email us.
Why get it checked now?
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.
Before you book any surveyor

- Which limits apply to the survey
- How they plan to inspect the roof safely
- Whether VAT is in the quoted price
Useful tips for Portsmouth property owners
A survey works best with a little help from you, before and after. Some tips:
- Keep outlets and gutters clear to stop water sitting
- Remember the conditions on the day affect the results
- Use the report as a baseline for later checks
- Take photos of stains as they appear, so we can compare
Many people send the report to roofers, who can then quote for the areas shown. Each thermal image is matched to a normal photo, so the areas are easy to locate.
Have small defects in the covering fixed early. Water that gets under a covering can spread a long way before it shows.
Should I look at the roof myself first?
Watch the gutters in a downpour, from a window or the ground. Overflowing water can be a sign of a blockage or a gutter that has dropped.
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Share it with us as you book and it will help the survey.
Your questions about thermal roof surveys in Portsmouth
I live in a flat. Can you survey the roof?
Yes. A shared roof needs access agreed first. Tell us about it as you book and we will explain what’s needed.
Which days do you carry out surveys?
Surveys can be booked for any day of the week: weekdays, Saturdays and Sundays. Just let us know the days that suit you.
Are you structural engineers?
No. We’re experienced roof surveyors, and visible signs such as sagging are noted, but we don’t provide calculations or an engineer’s opinion. If one is needed, the report says so.
Do I need to be at home?
Not always. An outside-only look can be arranged beforehand, but anything inside needs someone there to give access.
What conditions are best for thermal imaging?
The results depend on the weather. A dry surface, little wind and a sunny spell beforehand help most. We record the conditions in the report, so you know how much weight to give the images.
Which survey includes thermal imaging?
It is part of the Premium Survey, from £400. An in-person consultation and a follow-up 12 months later are included too. Larger commercial roofs are quoted for their size.
What does a thermal roof survey show?
It records surface temperature across the roof. Unusual patterns can point to trapped water, gaps in insulation or heat escaping, which we then check with moisture readings.
