About our roof leak investigation in Hamsey Green
Flat roofs leak in their own ways. Common causes are splits and blisters, tired upstands and outlets that do not drain. Ponding water makes any weakness worse. We check both the covering and the room underneath. Flat roofs over extensions, garages and dormers are frequent sources of leaks. An ageing felt roof is a frequent culprit. We survey chimney stacks, rooflights and dormers and valleys and parapet gutters, and people most often book us about damp patches next to the stack and leaks that appear only in driving rain.
In a village or hamlet like Hamsey Green, 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.
The Standard Survey adds moisture detection, a structural check and a follow-up consultation. The Premium Survey adds thermal imaging, drone inspection where applicable, structural analysis and an in-person consultation.

Your questions about roof leak investigations in Hamsey Green
Do you carry out roof surveys in Hamsey Green?
Yes, Hamsey Green is within the area we cover. Our area covers London and South East England. You can ring 07833 053749 or use the contact form with the address and a few details, and we will talk through which survey suits.
Does a conservation area affect roof work in Hamsey Green?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. The answer matters most when a change of material is on the cards.
Is thermal imaging part of a leak investigation?
It can, when the conditions are right. The best results come after a sunny day, on a dry roof with little wind. Damp areas can hold heat differently from dry ones. We always check what it shows with moisture readings.
Is it a structural engineer’s report?
No. Visible signs such as deflection or sagging are recorded, but we do not provide calculations or an engineer’s opinion. If one is needed, the report says so.
Is this a RICS survey?
No. We are experienced roof surveyors, and our survey covers the roof rather than the whole building. If you need a full building survey, you will need a RICS survey as well.

Useful tips for Hamsey Green property owners
Some practical points come up on survey after survey. They’re worth knowing whatever the roof:
- Take dated photos of the leak
- Don’t touch fittings that water is reaching
- Move stored items away from the hatch
- Tell us if there are tanks or pipes in the loft
Your report arrives by email. It explains the likely entry point, the route the water takes and our recommendations. Turnaround is within 48 hours for Basic, 24 to 48 hours for Standard and the same day for Premium.
After a downpour, look in the roof space with a torch, keeping to boarded areas. Look for drips, damp patches and stains on timbers. Photograph anything new.
Do you need a roof leak investigation in Hamsey Green?
A gutter that overflows can soak a wall and mark the ceiling inside. Hidden gutters behind parapets cause the most trouble, because when they block, water backs up and runs inside.
Look out for signs like these:
- Brown rings on upstairs ceilings
- Damp on a chimney breast
- Wet patches high on an inside wall
- Wet patches on loft insulation
For an older house near a landmark such as St Antony, water on an older roof tends to find its way in at the lead, the valleys or the chimney.
Questions to ask before you book
- Are they insured for the work?
- Will the report include photos?
- Whether the price includes VAT
- Whether the roof space is looked at, where there is one
Roof leak investigations in Hamsey Green: local notes
About 2.8 miles north lies Addington Palace, a reminder of how long the area around Hamsey Green has been built on. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years. In Surrey, older roofs are frequently handmade clay tile, with tile-hanging on many upper walls. A few of Surrey’s oldest buildings have heavy Horsham stone slab roofs. The covering and its details give the first clues when tracing where water is coming from.
Homes near green spaces such as Blanchman's Farm can get more leaves in their gutters in autumn, and an overflowing gutter soon means a wet wall. If you let a flat or house near Upper Warlingham station, a clear finding on where water gets in helps you brief a roofer straight away.

How the survey changes by roof type
Flat roof upstands and outlets
Each flat roof relies on its outlets to drain. When one blocks, water ponds and finds any weak spot. We check outlets and the covering around them.
Chimney stacks
A stack has several possible ways in for rain. Each is checked from every safe viewpoint, and look for damp on the breast inside.

Roof problems in a rented home affect tenants as well as the building. A survey shows what needs attention, so you can plan the work with less disruption.
If you own several properties, surveys can be booked for more than one address. To discuss a number of properties, ring 07833 053749 or send us an email with the addresses.
The survey, step by step
On the day, we start by asking what you’ve noticed and what you need to know. We then inspect everything that can safely be seen, using the ground, windows, the loft and a drone where applicable. Most surveys take about one to two hours for most homes, though a hard-to-trace leak can take longer. In a small place like Hamsey 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.
- You pick a Basic, Standard or Premium Survey.
- We agree a date, including weekends.
- We inspect inside and out, starting from the stain.
- Moisture detection and thermal imaging are used where your package includes them and they help.
- The report explains the likely entry point and what needs attention.
How to prepare
- Keep pets out of the way during the survey
- Point out any leaks or damp patches
- Move anything stored under the loft hatch
How to book
Most bookings start with a short call: ring 07833 053749 or drop us an email, and we’ll ask about the building and what you need. You will have a price before anything is arranged.
