Wind, rain and roofs in Cooper's Green
Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates, with flat-roofed extensions, dormers and garages common everywhere. Where water gets in depends a good deal on what the roof is made of and how it is detailed. Cooper's Green is part of Hatfield, one of the post-war new towns. Homes from the post-war decades are common in the new towns, many with low-pitched roofs in concrete tiles and flat-roofed garages or porches. Leaks on homes like these frequently come from flat-roofed additions or from rain driven up under low-pitched tiles.
Shop and office owners around The Maltings may find that a quick answer on where water is coming in keeps a business running. For site and facilities teams at buildings such as Howe Dell Primary School, tracing a leak on a big roof starts with where the water appears and works back. Historic houses like Hatfield House, about 2.7 miles east, show how far back building around Cooper's Green goes. Older roofs around here can leak at old repairs as readily as at original details.

Roof leak investigations for homes and businesses in Cooper's Green
Our job is to find the likely source and tell you. The report shows, with photos, where we believe the water gets in and how it travels, and recommends what should be done. It gives any roofer a clear brief. The investigation finds and explains the cause, while the repair is a separate matter. We survey the roof space, lead flashings and rooflights and dormers, and common reasons people get in touch are leaks at a dormer or roof window and a leak that comes and goes with the weather.
Somewhere as small as Cooper's Green, older roofs have often been repaired many times. A new leak may be fresh damage or the latest sign of long-term 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.
The report doesn’t just list problems. For each finding, it explains what it is, why it matters and what we’d recommend, so you can decide what to do next.

How the survey changes by roof type
Valleys
A valley leak can appear well away from the valley inside. We trace the route from the loft where there’s safe access.
Slate and tile slopes
A gap in the coverings exposes the underlay. Ageing felt eventually lets water through.
Cooper's Green: your questions answered
Is Cooper's Green within the area you cover?
Yes, we do. We work right across London and South East England, and smaller places are part of that. Longer journeys are simply planned beforehand.
Does a conservation area affect roof work in Cooper's Green?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it is worth checking before planning any.
Will you walk on the roof?
Only if it is safe. We check everything that can be seen safely: from the ground, from windows, from inside the roof space, from the roof where it is safe and by drone where applicable. Anything we cannot see is noted in the report.
Can you trace a leak in dry weather?
Often, yes. Leaks leave clues, such as staining, damp timber and moisture in materials. Intermittent leaks can be harder, so photos and notes from when it leaks help a lot.
Will you definitely find the leak?
We cannot promise to find every leak on one visit. Many leave clear signs, but some only appear in certain weather. The report sets out what we found and the most likely routes.
Which days do you carry out surveys?
Surveys run on any day of the week. To find a day that suits you, call 07833 053749 or email us.
Does this replace a RICS home survey?
No. It is a specialist roof survey, not a RICS Level 2 or Level 3 building survey. It focuses on the roof, so it sits alongside a building survey rather than replacing it.
How the survey works
You don’t need to do much on the day. Show us any stains, drips or problem areas you know about, and we will take it from there. A typical survey takes roughly 1–2 hours for most houses, while a commercial roof takes nearer three to four hours. In a small place like Cooper's Green, access is typically the main thing to plan. Mention any outbuildings, barns or garages you want included, and anything about the roof you already know. Visits can be on weekdays, Saturdays or Sundays.
- We start with your notes and photos of the leak.
- Inside, we check the stain and the ceiling around it.
- In the loft, we follow any signs of water back towards the roof.
- We inspect the likely entry points outside, from the ground, windows and the roof where safe.
- You receive a report with the likely source, photos and recommendations.
Before we arrive
- Find any records of previous roof work
- Keep pets in another room
- For a flat or shared roof, check access with the building owner or managing agent
How to book
Surveys can be booked for weekdays, Saturdays or Sundays. To arrange a day that suits you, ring 07833 053749 or send us an email.

Tips from our surveys
There’s plenty you can do without going near the roof. What helps most:
- Have an electrician check any wet fittings
- Let us know what has already been tried
- Move stored items away from the hatch
- Put a bucket under the drip and move valuables
If the leak turns out to be condensation, the report says so, with recommendations on ventilation. It saves chasing a leak that is not there.
Keep the loft space ventilated. Good airflow reduces condensation, which is often mistaken for a leak. Check insulation doesn’t block airflow at the eaves.
What happens if roof problems are left?
Damp in a ceiling or loft can lead to mould. It’s unpleasant, and it is harder to deal with once established. Stopping the water is the first step. In a small place like Cooper's Green, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Our price is from £150, including VAT. What you pay depends on the size and height of the roof, access and the package you choose.
What you get with us
- Insured for professional indemnity and public liability
- Thermal imaging and drones used where they help
- Clear package prices, including VAT
- Independent findings on the roof’s condition

Rented homes, blocks and businesses
If the property is let, the agent or a tenant can let us in. We survey on weekdays and at weekends, which helps when tenants work during the week.
Landlords and letting agents in Cooper's Green book surveys as well as householders. A report with photographs gives you a clear record of the leaking roof.
Checking the roof from the ground
During heavy rain, look at the gutters from ground level or a window. Overflowing water can be a sign of a blockage or a gutter that has dropped.
A lot can be seen from the ground. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Please don’t climb up for a closer look.
