Common roof problems in Hertford
After a long-running leak, insulation under a flat roof can stay wet. Knowing how much of the roof is affected helps decide between a local repair and more. Thermal images and moisture readings together can show the likely extent.
Most people get in touch when they’ve noticed one of these:
- Missing or slipped insulation
- Cold areas below the roof
- Wet areas near outlets and upstands
- Stains that keep coming back
A roof leak in a hotel or guest house around Hertford means lost rooms as well as repairs, so it pays to find faults before guests do.
What to check before booking
- Whether the roof space is looked at, where there is one
- Are they insured for the work?
- Which parts of the roof they’ll actually see
- When you will get the report
Thermal roof surveys for homes and businesses in Hertford
Thermal imaging works best in the right conditions. A sunny day before the survey, a dry roof surface and little wind all help. Rain, wind and cloud can all make the patterns weaker. We talk through the forecast as you book, and the report explains how the conditions on the day affected the results. We survey ceilings below the roof, commercial roofs and flat roofs, and people most often book us about thin or uneven insulation in the roof and possible trapped moisture under a flat roof covering.
Older homes in a town like Hertford may lose heat through roofs with little or no insulation. A thermal camera shows those cold and warm patches, and some of them can point to moisture. What it shows is surface temperature, not water itself, so findings are checked with moisture readings. Results depend on the conditions, which is why the date is chosen with care.
We write the report in plain English, so you do not need to be a roofer to follow it. Photographs show what each point refers to.

What a thermal roof survey does not cover
Some things cannot be seen without opening up the roof, so a survey has limits:
- Structural calculations, which need a structural engineer
- Hidden layers that need to be opened up to check
- Proving moisture from the images alone
Not sure which survey suits your roof? You can phone 07833 053749 or drop us an email and we will tell you. What a survey covers and doesn’t.
What this survey covers
- Commercial roofs
- Loft conversions
- Ceilings below the roof
- Insulated roof spaces
- Flat roofs
- Pitched roof slopes
How the survey works
Every roof is different; as a rough guide, the survey takes between one and two hours for most homes, plus time to check any thermal findings with moisture readings. If you have questions on the day, just ask. For a visit in Hertford, we need access to the loft, any rooms with leaks or stains, and the outside of the building. If there’s a side gate or a rear garden, let us know how to reach it. Weekday and weekend visits are available.
- First we discuss the roof, any damp and the forecast for the visit.
- The roof is inspected visually from safe positions.
- 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.
Before we arrive
- Check we can get to the back of the property
- Note where any stains or damp appear
- If it is not your property yet, arrange access through the agent

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. Around Hertford, gutters that overflow soak the wall below, and damp follows inside. A slipped tile or worn flashing does the same higher up. Left alone, both only get worse.
Prices quoted always include VAT, and the written report is part of the package. Thermal roof survey starts from £400, including VAT. Size, height and access decide where your roof falls.
What you get with us
- CAA-registered drone operator (Flyer ID and Operator ID)
- An independent view of the roof
- PI and public liability insurance
- Surveys seven days a week
Thermal roof surveys in Hertford: local notes
Hertford has a number of hotels within about a mile and a half, and like offices and blocks, hotels frequently sit under flat roofs. For hotels and other commercial buildings, large roofs are where aerial photos and thermal images show the most at once. If your survey includes the drone, the flight is checked against the Drone Safety Map first.
The streets around a church like Hertford United Reform Church are frequently among the oldest in a place, and if yours is one of the older homes nearby, steep roofs, tall chimneys and hidden valleys can be hard to see from the ground, and that is where a view from above or with a thermal imager helps. Anyone responsible for a site like Mill Mead Primary School will know that thermal images can show where wet insulation sits under a big flat roof.

Roof by roof
Parapets, valleys and junctions
When valley or parapet gutters overflow, water can get into walls and ceilings. Thermal images, checked with moisture readings, can help trace it.
Loft insulation
From inside the loft, thermal imaging can show gaps in insulation and cold spots. We look where there is safe access.
Your questions about thermal roof surveys in Hertford
Do you carry out roof surveys in Hertford?
Yes, Hertford is one of the places we work. The survey and report are the same in Hertford as anywhere else, and visits run on weekdays and weekends.
Is my home in Hertford listed or in a conservation area?
We cannot 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.
Is it a structural engineer’s report?
No. We note visible signs such as sagging or deflection, but we do not carry out calculations or give an engineer’s opinion. If we think you need an engineer, the report says so.
I live in a flat. Can you survey the roof?
Yes. Shared roofs just need a little more planning. Let us know about it when booking and we will explain what’s needed.
Does the report include photographs?
Yes, plenty. Each finding is shown in a picture where possible.
Does someone need to be in?
If the survey includes the loft or the inside of the building, someone needs to let us in. Access is agreed with you when booking.
