Clothall Flat Roof Survey
Surveys of flat roofs on homes, extensions and commercial buildings in Clothall. More than 5,000 surveys completed across London and South East England.
- Failed upstands where the roof meets a wall
- Ponding water that doesn’t drain away
- Splits, cracks and crazing
How the survey works
After the inspection, everything we found is written up as a report with photographs. On timing, it usually takes about one to two hours at most homes, or half a day or so for a commercial building. Around Clothall, older homes can have small or awkward roof spaces, so it helps to know whether there is a loft hatch and how easy it is to reach. We only go where it’s safe.
- We start with the details: the address, the roof’s use and any leaks or stains.
- The roof is inspected from safe viewpoints, and from the roof itself where that is safe.
- The covering, falls, upstands, outlets, edge trims and rooflights are checked and photographed.
- Where there’s safe access, we look at the ceilings and spaces below for signs of water.
- We send a written report with photos, the defects we found and what we recommend.
Before the survey
- Let us know where we can park nearby
- Make a note of anything you’d like us to look at
- Find any records of previous roof work

Flat roof survey in Clothall
A flat roof leak often travels before it shows on the ceiling. It can run along the deck from a split, an open lap or a failed upstand some distance away. That’s why we check every detail across the roof, not only the area above the stain, with photos of anything that could be letting water in. Whoever carries out the work then has a clear starting point. If you’re worried about splits, cracks and crazing and failed upstands where the roof meets a wall, we can find out what’s behind it, whatever the roof.
Somewhere as small as Clothall, flat roofs tend to be on extensions, garages and converted outbuildings. The checks are the same as anywhere: the covering, the edges, the upstands and where water drains away. We simply plan the journey and access in advance. Garages and outbuildings are easy to forget, so mention any you want included when booking.
The report is written in plain words, so it makes sense without any roofing background. Each point is backed by a photograph where possible, and recommendations are put by urgency where it matters.

Questions from Clothall
Do you carry out roof surveys in Clothall?
We do. Every survey there gets the same written report with photos, and visits run on weekdays and weekends.
Does a conservation area affect roof work in Clothall?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you’re planning to re-roof in a different material.
How long does the survey take?
It typically takes between one and two hours on an ordinary house, and longer for a large or complex roof. We will confirm the timing when you book.
I live in a flat. Can you survey the roof?
Yes, once whoever controls the roof agrees access. We check the parts we’re given access to.
Do you go up onto the roof?
Where it’s safe, the roof is inspected from the roof itself. If not, we use safe viewpoints and look inside, and the report says if any part couldn’t be seen. We don’t walk on fragile rooflights or sheeting.
Should I worry about standing water on my flat roof?
Water that lies on a flat roof for days is a sign that something needs attention. The cause may be the outlets, the falls or the deck. We check each of these and record what we find.
Does the weather affect the survey?
A survey can usually go ahead in light rain, and it can even help show where water is getting in. Strong wind or heavy rain can stop drone flights and make roof access unsafe, so we’ll agree a new date if the weather isn’t suitable.
Flat and commercial roofs around Clothall
Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. Listing and conservation areas can both shape what roof work is allowed on an older home. Your council and Historic England’s list will tell you where you stand, before anyone quotes for re-roofing.
Landlords with a home close to Baldock station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round. If you own one of the older houses in the streets near Church of St Mary, the flat roofs on later extensions tend to wear out long before the main roof.

Near you in Clothall
We work in homes and buildings around The Knights Templar School. The nearest railway station is Baldock station, about 2.2 miles north-west. Other landmarks nearby include First Garden City Heritage Museum (3.1 miles west) and Clothall Castle (under half a mile south-east). Green spaces nearby include Pryor's Wood.
Can I check my roof myself?
The one thing to avoid is getting up close. Slates, tiles, flat roofs and rooflights can give way. That part is for a survey, using safe viewpoints and a drone where applicable.
Your own check is a good start, but it isn’t a survey. You will not see flashings, valleys or the backs of chimneys properly from the ground.
When to book a survey in Clothall
Buyers frequently book after their home survey suggests a closer look at a flat roof. Owners and managing agents use a survey to plan upkeep, or ahead of a sale or a new lease. In each case, the report gives a written, photographed record of the roof’s condition.
Look out for signs like these:
- Splits and cracks in the covering
- Failed upstands where the roof meets a wall
- Raised blisters across the surface
- Loose or cracked edge trims
If you look after a building such as Weston Primary School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.
Questions to ask before booking
- What happens after the report arrives
- Which limits apply to the survey
- Which parts of the roof they’ll actually see
- Whether you get a written report with photos

Why get it checked now?
Before replacing a flat roof, it helps to know if you really need to. At times the trouble is a handful of failed details, and at times the whole covering is worn. The report sets out what we found, so you can make that decision with a roofer. Outbuildings and barns around Clothall are easy to forget, but a failed roof there can spoil what’s stored inside. A quick look before winter can save a lot.
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how it can be reached and seen safely. Prices start from £150, including VAT.
Why us?
- An independent look at the roof
- Clear package prices, with VAT included
- Two decades and more of roof surveys
- Surveys seven days a week

Tips that help
A few practical points come up again and again on our surveys. They apply to most roofs:
- Note where water lies after a downpour
- Book a survey every few years
- Check new fixings through the roof are properly sealed
- Ask contractors to protect the roof if they work on it
Questions about the findings are always welcome. The Standard Survey includes a follow-up consultation and the Premium Survey an in-person consultation, so you can talk the findings through.
Check the roof from a window after a downpour. If water is still there a day or two later, have it checked.
