Thermal Roof Survey in Portswood
Thermal imaging to find moisture and heat loss patterns in a roof in Portswood, carried out by an experienced roof surveyor. You get a clear written report with photos.
- Water getting in at parapets and stacks
- Damp around roof outlets and upstands
- Heat escaping through the roof
How the survey changes by roof type
GRP fibreglass roofs
GRP surfaces can be shiny, which affects thermal readings. We allow for reflections and confirm findings with moisture readings.
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.
Thermal roof surveys for homes and businesses in Portswood
Your report sets out the thermal images alongside ordinary photos, making it clear where on the roof each pattern is. Each one comes with an explanation, the moisture readings and our recommendation. Premium reports are sent the same day. If you have questions, the in-person consultation gives you time to go through them. There’s a 12-month follow-up as well. We survey loft conversions, pitched roof slopes and commercial roofs, and common reasons people get in touch are stains that keep coming back and thin or uneven insulation in the roof.
Around Portswood, plenty of roofs are low enough to see partly from the garden or the street. The parts you cannot see, such as rear slopes, valleys and chimney tops, are where a drone or thermal camera adds detail. Both depend on the weather on the day. Close-up images often show wear on ridges, verges and flashings that cannot be judged properly from ground level.
How fast the report arrives depends on the package: the Basic Survey within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey on the same day.

What happens if roof problems are left?
Thermal images can suggest the extent of wet areas without cutting into the roof. It helps when deciding whether to patch an area or replace the roof. With lower homes, common in places like Portswood, there’s little between a roof defect and the ceiling, so water can show inside quickly once it gets past the covering. Catching the cause first saves redecorating as well.

Useful tips for Portswood property owners
A little preparation and a few simple habits help, both for the survey and for the roof itself. Our tips:
- Tell us where and when you’ve seen damp or stains
- Check from ground level or a window, never by climbing
- Photograph damp patches with the date
- Remember the conditions on the day affect the results
You can pass the report to a roofer so they can see where the problem areas seem to be. Each thermal image is matched to a normal photo, so the areas are easy to locate.
Watch for new damp patches on ceilings beneath the roof. Early action keeps insulation from staying wet.
Flying and imaging in Portswood
The coast is about 3 miles or less from Portswood, and wind off the sea can be strong. Thermal imaging works best after a sunny day, with a dry roof surface and little wind, so the date is chosen with the forecast in mind. Within a mile and a half or so of Portswood there are several hotels, and hotels, like offices and blocks of flats, often have flat roofs. For hotels and other commercial buildings, large roofs are where aerial photos and thermal images show the most at once.
For businesses in and around places like Marlands Shopping Centre, thermal images can show trapped moisture across a wide commercial roof. Take a building like St Denys Primary School: thermal images can show where wet insulation sits under a big flat roof. If you run a hotel or guest house in or near Portswood, a roof problem can mean rooms out of use.

What else we do in Portswood
What a survey costs
Not every roof costs the same to survey, and it comes down to:
- Whether you choose the Basic, Standard or Premium Survey
- Extra roofs, like extensions, dormers or garages
- The roof’s overall size
- Commercial roofs and larger buildings
One thing that affects the price is the package: Basic from £150, Standard from £250 or Premium from £400, all including VAT. Size, height and access can affect the price too.
Booking your survey
When you call or email, these details help:
- The reason for the survey, like buying, a leak or storm damage
- Any stains, drips or damp patches you’ve seen indoors
- Where the property is, with the postcode
- Any deadline, like an exchange date
Photos help, if you have them. Pictures from the ground or a window are fine; never climb up to get a better view. To get started, call 07833 053749 or email us.
How the survey works
After the inspection, everything we found is written up in a report with photos, sent to you by email. As for time on site, it typically takes about 1–2 hours for most homes, plus time to check any thermal findings with moisture readings. A visit to a smaller place like Portswood is no different on the day: we look from the ground, from windows, from the loft and from the roof where it’s safe. Point out any stains, cracks or loose pieces you’ve spotted.
- 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.
- Moisture readings are used to check what the camera shows.
- You get the report the same day, with an in-person consultation to follow.
How to prepare
- Unlock side gates and any roof access doors
- Have any questions written down, so nothing gets missed
- Check the loft hatch can be reached

Related advice
Your questions about thermal roof surveys in Portswood
Are there drone restrictions around Portswood?
The answer turns on the exact location and the conditions on the day. Portswood is inside, or right on the edge of, the flight restriction zone around Southampton Airport. We ask the airport for permission before flying there, and only fly if it is given. A small drone can’t fly safely in high wind or heavy rain.
Is Portswood within the area you cover?
We do. A small place gets exactly the same survey as a big one.
What can thermal imaging tell me about my roof?
The images show how warm or cool each part of the surface is. Unusual patterns can point to trapped water, gaps in insulation or heat escaping, which we then check with moisture readings.
Will you walk on the roof?
Only if it is safe. We inspect what can be seen safely: from the ground, from windows and vantage points, from the loft space, from the roof itself where safe and by drone where applicable. The report says if anything couldn’t be seen.
Does someone need to be in?
Not necessarily. If we only need the outside, we can agree that in advance, but anything inside needs someone there to give access.
Can you survey a shared roof?
Yes. A shared roof needs access agreed first. Tell us about it when booking and we’ll explain what’s needed.
What conditions are best for thermal imaging?
Conditions on the day affect the results. It works best after a sunny day, with a dry roof surface and little wind. Rain, wind and heavy cloud can weaken the patterns, so we talk through the forecast when booking.
