Ask three firms what a roof survey costs and you may hear three very different numbers, because they are often describing three different jobs. One is a roofer on a ladder with a camera and a short written note. Another is a drone flight with stills. A third is a thermal imaging survey with a full report. The word survey covers all of them, and the price follows the method, the time on site and the paperwork that comes back.
This guide prices paid surveys using published national ranges, then looks at what changes the figure on a Stroud roof: height, access, roof shape and the report you want. Every figure below comes from a published national cost guide and describes the market, not a Supreme Roofing price. Whether a free visit is worth having is a different question, which we weigh in our answer on free roof inspections. For the wider service, start at roof inspections and surveys.
Three kinds of survey, three typical price bands
MyBuilder's roof inspection cost guide, updated in August 2026, gives an overall range of £150 to £500 and splits it by method. A standard survey, where a roofer looks over the roof and writes up what they find, sits at £150 to £250. A drone survey is quoted at £200 to £400. A thermal survey, which uses an infrared camera to pick up temperature differences, is quoted at £300 to £500.
| Survey type | Typical UK range | What you mainly pay for |
|---|---|---|
| Standard | £150 to £250 | Roofer's time, close visual check, short report |
| Drone | £200 to £400 | Flight, image processing, annotated stills |
| Thermal | £300 to £500 | Infrared equipment, conditions, interpretation |
These are national figures from one guide, dated 2026, and they describe the typical fee for the survey alone. They do not include any repair, and they do not include scaffold, which comes up further down.
Why the bands overlap
A large drone job on a complicated roof can cost more than a quick thermal check on a small flat roof. The bands are a guide to the middle of each market, not fences. Two firms offering the same method can still differ, because one includes a written report with photographs and the other hands over a verbal summary.
What the survey fee is actually paying for
Strip a survey back and the fee covers four things: travel and time on site, the method, the interpretation, and the write-up.
Time and travel
A roofer has to get to the property, walk round it, look at every slope, then go into the loft. On a modest terrace that is quick. On a rambling house with several roofs, an extension and a chimney stack, it is longer. Time on site is one of the quieter drivers of price, and our answer on how long a roof inspection takes goes into it.
Method
A ladder, a pole camera, a drone and a thermal camera each have a cost to own and to use. Drones and thermal cameras need training, a suitable day and processing afterwards, and the price reflects that. The cheaper methods are not worse; they answer different questions. Our guide to drone roof surveys covers what the flight does and does not show.
Interpretation
Images are only as useful as the person reading them. A slipped tile, a lifted lead flashing and a stained patch of ceiling mean different things, and a roofer who can tell the difference is the main thing you are buying.
The write-up
A report with dated photographs of your own roof, numbered defects and a note of what to do about each costs more to produce than a text message. It is also the part you can use afterwards, whether that is to get repair quotes, to talk to a seller or to support an insurance claim.
Why two Stroud surveys can differ in price
Several factors push a survey toward the top or bottom of its band. Most of them are about the building rather than the method.
Size and shape
More slopes, more valleys, more chimneys and more dormers mean more to check. A detached house with a cross-wing and a rear extension will cost more to survey than a mid-terrace with one pitch each side.
Height and access
A three-storey house has a bigger gap between the ground and the eaves than a bungalow. Where the roof can be reached safely from a ladder, the survey is simple. Where it cannot, the surveyor needs another way to see it, such as a pole camera or a drone, or a platform. Stroud's terraced hillsides and steep lanes matter here: a house with no space for a ladder at the front, or a back slope that faces a retaining wall, changes how the visit is done. Access like that is priced into the quote before the visit and does not surface as a surprise on the day.
Roof covering
Natural slate and stone slate are walked on with care, or not at all, because they break. A stone-slate roof is surveyed slowly and often from below or from a ladder, which takes longer than a concrete tile roof that can be inspected at close quarters.
Flat roofs and lofts
A flat roof is usually a single short visit, but it may need a closer look at upstands, outlets and joints. A loft that is boarded, full of storage or has no easy hatch adds time.
The report you ask for
A short written note and a full photographic report are priced differently. Say at the start which you need.
Scaffold, towers and access equipment
Most surveys do not need scaffold, and most survey fees do not include it. Where a survey does call for access equipment, it is usually because the roof cannot be seen properly any other way, or because a defect needs hands-on checking at height.
The figures to know are for scaffolding on a re-roof or major repair rather than a survey. MyBuilder's new roof guide, updated in August 2026, puts scaffold at about £1,125 for a typical house, and Checkatrade's roof replacement guide, updated in October 2026, gives £700 to £1,300 plus VAT. MyBuilder's fascia and soffit guide puts scaffold at £20 to £40 per m². Those numbers show why a surveyor tries to avoid scaffolding for the survey itself: it can cost many times the fee.
The more useful question is whether the survey will lead to a job that needs scaffold. If it will, scaffold belongs in the written quote for that job. It should not be hidden in a survey fee or turn up later as an extra.
If a quote for a survey mentions scaffold, ask why. A visual survey of a house whose roof can be seen from a ladder or a drone should not need one.
Our approach is to say before the visit whether we expect to need anything beyond a ladder and a camera, which puts the cost of getting up to the roof on the table early.
Reading a survey quote
A clear quote for a survey lets you compare like with like. Look for these points.
Which method
Standard, drone or thermal. If a firm says only survey, ask which. A drone flight is a quite different thing from a roofer on a ladder.
What the fee includes
Check whether the figure covers a loft inspection, photographs of the roof, a written report and any follow-up call. Some firms charge separately for each. Our guide to what a roof survey covers lists the parts of the roof a proper survey looks at, so you can check a quote against it.
Whether VAT is shown
National cost guides state their basis differently, and Checkatrade marks many of its figures as plus VAT. Because roofing work is normally standard-rated at 20 per cent, ask whether the number you have been given includes it. Your quote will show VAT, and it should be clear which figure you pay.
What comes after
A survey is a step, not an end. Ask what happens to the findings. Any quote for the work that follows should say clearly what it covers. Put a survey fee next to what its findings could cost to fix, and the fee usually looks small.
What a good report is worth
Dated pictures and a plain list of defects turn a survey from an opinion into a document you can act on, whoever does the repair.
Setting the fee against what a survey can find
A survey fee is easiest to judge against the repairs it might head off. National guides give some reference points, all typical UK ranges for 2026.
MyBuilder's roof repair guide gives £100 to £300 for a minor roof repair and £500 to £1,000 for a moderate one, with major repairs starting around £2,500. Its slate roof guide gives £60 to £120 for a single slate, and £300 to £600 to have ridge tiles re-bedded or replaced. For lead flashing, MyJobQuote gives £150 to £250 for patching around a chimney and about £570 on average for a full replacement. On a full re-roof, MyBuilder gives £5,000 to £12,000 as a typical range.
A £150 to £250 survey that finds a failing ridge before it lets water into the loft sits comfortably against those figures. So does a survey that confirms a roof has years left and saves you a re-roof you were told you needed. The value is in the decision it supports.
When a paid survey is hard to justify
If you already know exactly what is wrong, such as a single slipped tile you can see from the garden, a repair quote may be all you need. A survey earns its fee when you do not know what you are looking at: before buying, before a re-roof, after a storm, or when you suspect a leak you cannot trace. Our guide to drone roof surveys covers the case where the roof is hard to reach.
Every price on this page is a national range from a published guide and says nothing about what any firm charges. We publish typical ranges on our service pages for exactly that reason: you should know the territory before anyone visits.
