Why act early in Dagnall
Trapped water can harm decks, timbers and ceilings the longer it stays. Looking now, while the damage may still be limited, keeps more options open. Older and listed buildings around Dagnall may need consent and matching materials for repairs, so leaving a defect until it’s urgent leaves less time to plan.
The cost of a survey depends on the roof: its size, its height, how many sections it has and how safely it can be seen. Our price is from £400, including VAT.

About our thermal roof survey in Dagnall
A thermal survey is not a quick fix for every roof problem. Sun, shade, reflective surfaces and wind can all change what the camera shows. We back up the images with moisture readings and a careful look at the roof. Our report says plainly what the camera picked up and how sure we can be. If a finding cannot be confirmed, the report suggests a next step. Common reasons to book are missing or slipped insulation and water getting in at parapets and stacks, on loft conversions, pitched roof slopes and flat roofs.
In a village or hamlet like Dagnall, roofs can be steep, old and hard to see from the lane. Close-up drone photos and thermal images help show what can’t be reached safely. Weather and airspace are checked ahead of the visit. Steep slopes and tall chimney stacks are where a close-up view adds the most.
The report doesn’t just list problems. It explains what we found, why it matters and what we recommend, so you can decide what to do next.

Flying and imaging in Dagnall
England has around 10,000 conservation areas and about 500,000 listed buildings. If your home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission, so the council is the place to ask. If your survey includes the drone, the flight is checked against the Drone Safety Map first.
If your house is among the older ones in the streets near Church of All Saints, tall stacks and steep slopes are easier to judge with close-up aerial photos than from the pavement.

Common roof problems in Dagnall
Flat roofs that have leaked for a while can have wet insulation under the covering. Owners want to know how far it has spread before deciding what to do. A thermal survey, checked with moisture readings, can give a much clearer picture.
Signs worth acting on include:
- Ceilings that feel colder in places
- Areas losing heat at the eaves and junctions
- Possible trapped moisture under a flat roof covering
- Stains that keep coming back
If you look after a building like Dagnall VA Church of England School, a view from above covers a wide roof far faster than walking it.
Questions to ask before you book
- Which limits apply to the survey
- Which parts of the roof they’ll actually see
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- Whether the inside of the roof is included
For landlords and managing agents
We also survey roofs for businesses and commercial landlords. Bigger roofs take more time.
A roof problem in a let property affects your tenants as well as the building. A survey helps you spot issues early and plan the work with less disruption.
How the survey works
After the inspection, everything we found is written up as a written report with photos, emailed to you. On timing, most surveys take roughly 1–2 hours for most houses, while a commercial roof takes nearer three to four hours. In a small place like Dagnall, access is usually the main thing to plan. Mention any outbuildings, barns or garages you want included, and anything about the roof you already know. Weekday and weekend visits are available.
- You let us know about the roof and any damp, leaks or cold rooms.
- We check the conditions and note how they may affect the images.
- A full inspection and thermal imaging are carried out together.
- Moisture readings are used to check what the camera shows.
- The Premium report reaches you the same day, and we go through it with you in person.
Before we arrive
- Let us know where we can park nearby
- Check we can get to the back of the property
- Point out any leaks or damp patches
Getting a price
A quick phone call is normally the easiest start: call 07833 053749 or drop us an email, and we will ask about the building and what you need. You will have a price before anything is arranged.
Related advice
Before and after the survey
A few practical points come up again and again on our surveys. They’re worth knowing whatever the roof:
- Clear leaves from outlets and gutters each autumn
- Keep dated photos of any marks on ceilings
- Keep the heating on as usual before a heat loss survey
- Ask us about the forecast if rain is expected
Premium Surveys include an in-person consultation, so you can go through the images with us. There’s a 12-month follow-up too.
Check that loft insulation is laid evenly and hasn’t been pushed aside. Gaps often appear after work in the loft.
Questions from Dagnall
How do I find out if my home in Dagnall is listed?
We can’t 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.
Do you cover smaller places like Dagnall?
Yes, Dagnall is covered. Our area covers London and South East England, from towns to the smallest villages. The journey is planned ahead, so it helps to know about access.
Do you take photos of the roof?
Yes. We photograph the roof as we go, and the report uses them to show each finding alongside our recommendations.
Is this an asbestos survey?
No. Asbestos surveys and sampling aren’t something we do. The report may flag materials that could contain asbestos on buildings built or refurbished before 2000, with a recommendation to have a specialist asbestos surveyor check before it is disturbed.
Will the survey show heat loss through my roof?
Thermal images can suggest where heat is escaping and where insulation may be missing. We do not give energy ratings or heat loss calculations, but the images show where improvements may help.
How long will you be at the property?
It typically takes about 1–2 hours for most homes, plus time to check any thermal findings with moisture readings. We will confirm the timing when you book.
Is thermal imaging useful on pitched roofs?
It can show heat loss and some damp, but it has more limits there. We explain what the images can and can’t tell you, and we check them with a visual inspection and moisture readings.
DIY checks: what’s safe
During heavy rain, look at the gutters from ground level or a window. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.
You can learn a lot from ground level. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Please do not climb up for a closer look.
