Wind, rain and roofs in Clothall
There are about 500,000 buildings on England’s list of listed buildings, and around 10,000 conservation areas. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material, so the council is the place to ask. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile, with flat-roofed extensions, dormers and garages common everywhere. Each of these roof types has its own typical places for water to get in.
For landlords with property near Baldock station, a tenant living with a leak needs the cause found, not just the stain painted over. If you live in an older home near Church of St Mary, old mortar, worn lead and slipped slates are the usual suspects when water gets in. Take a building like Weston Primary School: a leak through a large roof is often found some distance from where the water shows inside.
Clothall is about 3 miles east of Letchworth, in Hertfordshire. In Clothall, as across Hertfordshire, every roof gets the same careful survey. Our area takes in places right across Hertfordshire, large and small. Milton Keynes is in our area too.

How a roof leak investigation works in Clothall
Some leaks only appear in certain weather. Wind-driven rain, an overflowing gutter or snow melt may be what triggers it. Telling us when it happens helps a lot and so do photos. Even on a dry day, a leak typically leaves clues: stained timbers, tide marks and damp underlay. Moisture detection shows which materials are still damp. If you’ve noticed brown rings on upstairs ceilings and staining around the chimney inside, we can find out what’s behind it, whatever the roof.
In a village or hamlet like Clothall, older cottages and farmhouses often have roofs that have been patched over many years. That makes it hard to tell new damage from old wear, which matters if you are thinking of an insurance claim. The report says what was seen and what it points to. Older walls and timbers hold water for a long time, so it’s worth finding the cause soon.
Pictures do a lot of the work in our reports, because a photo of a cracked flashing says more than a paragraph. If something couldn’t be seen safely, the report is clear about it.

Your questions about roof leak investigations in Clothall
Do you cover Clothall?
Yes, Clothall is one of the places we work. Every survey there gets the same written report with photos.
Is my home in Clothall listed or in a conservation area?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Could my leak actually be condensation?
The two can look alike. Drips from nail tips, damp underlay over a wide area and poor loft ventilation point towards condensation. We check the pattern of damp and the ventilation, then say which is most likely.
Do you survey on Saturdays and Sundays?
Visits run seven days a week in the daytime, which suits people who work during the week. Let us know your preferred days as you book.
Can you inspect my roof with a drone?
Where it helps and it’s safe, yes. Flights depend on the weather on the day and airspace rules. We hold a CAA Flyer ID and Operator ID.
What’s in the report?
Written findings with photographs, covering the condition of the leaking roof, the defects we found and what we recommend. The Standard Survey adds moisture detection and a structural check, and the Premium Survey adds thermal imaging, drone inspection where it applies and structural analysis.
Can you trace a leak in dry weather?
Often, yes. Stains, tide marks, damp timbers and moisture readings normally point the way. Intermittent leaks can be harder, so your photos and notes from wet days are very useful.

Tips from our surveys
A survey works best with a little help from you, before and after. Some tips:
- Do not climb onto the roof to look
- Check the loft is accessible
- Keep water away from lights and sockets
- Check whether pipes or tanks run near the stain
If the leak turns out to be condensation, the report says so, and suggest how the roof space could be better ventilated. That avoids roof work that wouldn’t help.
Check the loft after heavy rain, with care and a good torch. Look for drips, damp patches and stains on timbers. Take photos of anything that changes.
DIY checks: what’s safe
If you have a loft with safe access, take a look inside. Use a torch and stay on the joists or boards, and look for staining, damp timber or daylight coming through.
A DIY look is useful, but it isn’t a survey. From ground level, valleys, flashings and the backs of chimneys are frequently out of sight, and those are details a survey looks at closely.
What we do, step by step
Photos are taken throughout the visit, so the report shows exactly what we saw. We take close-ups from wherever is safe, including by drone where it’s applicable and the weather allows. A typical visit takes roughly 1–2 hours, more where the leak is intermittent or the roof is large. In a hamlet or village like Clothall, a postcode doesn’t always lead to the right gate, so a few directions are welcome. The visit itself is the same as anywhere else.
- We start with your notes and photos of the leak.
- We examine the damp area and the rooms near it.
- From the loft space, we trace the water’s route where there’s safe access.
- Outside, we check flashings, valleys, chimneys, gutters and flat roof details from every safe viewpoint.
- You receive a report with the likely source, photos and recommendations.
Before the survey
- Find any records of previous roof work
- For a flat or shared roof, check access with the freeholder or managing agent
- Show us where any leaks or stains appear

Different roofs, different checks
Flat roof upstands and outlets
Outlets drain a flat roof. When one blocks, water ponds and finds any weak spot. We check outlets and the covering around them.
Chimney stacks
Chimneys let water in through pointing, flaunching, flashings and open pots. Each is checked from every safe vantage point.

There is no need for technical words. Just let us know:
- Dates you are working to, such as exchange
- How the loft is reached, if there is one
- Pictures of the roof from a safe spot, if you have them

To book a survey, ring 07833 053749 or drop us an email and tell us the address and what’s prompted the survey. You’ll know the price before anything is booked.
Why get it checked now?
Lingering damp encourages mould on ceilings and walls. It’s unpleasant, and it’s harder to deal with once established. Finding the leak comes first. For an older or listed building in a place like Clothall, repairs may need matching materials and consent, so a defect found early gives time to plan the work properly.
Every price we give includes VAT. Our price is from £150, including VAT. You’ll know the exact price before you book.
