Why act early in Thorpe Green
If a leak has been ‘fixed’ before and has come back, the cause was probably missed. We look past the obvious spot and check each likely route. That’s often what breaks the cycle. Where a roof is exposed, as many are in small places like Thorpe Green, driving rain gets into any weakness, and damp in older walls is slow to dry out.
Prices quoted always include VAT, and the written report is part of the package. Our price is from £150, including VAT. Size, height and access decide where your roof falls.

How a roof leak investigation works in Thorpe Green
Flat roofs leak in their own ways. Splits, blisters, failed laps, worn upstands and blocked outlets are common causes. Standing water puts extra pressure on every weak point. We check the roof surface and the ceiling below to narrow it down. Flat roofs over extensions, garages and dormers are frequent sources of leaks. Felt often lasts around 15 to 20 years, so age is part of the picture. We survey the roof space, slate and tile slopes and lead flashings, and the problems we’re asked to look at most are leaks at a dormer or roof window and water through the ceiling under a flat roof.
For a small place like Thorpe Green, the inspection is the same as anywhere: the journey and access are just planned in advance. It helps to know where the water appears, in what weather, and what you’ve seen outside, along with any repairs done before. If you have photographs of the water coming in, they help as well.
The report works through the roof section by section, from the coverings down to the gutters. You will see the good as well as the bad.

What a roof leak investigation looks like in Thorpe Green
Botleys Mansion, about 2.1 miles south, is one of the historic houses in the wider area around Thorpe Green. If your house is among the older ones, expect a mix of original materials and later repairs on the roof, and the council can say whether a home is in a conservation area. Many older homes in Surrey have handmade clay tiles and tile-hung upper walls. A few of Surrey’s oldest buildings have heavy Horsham stone slab roofs. Each of these roof types has its own typical places for water to get in.
Anyone responsible for a site like Thorpe CofE Aided Primary School will know that a leak through a large roof is often found some distance from where the water shows inside. If you own one of the older houses in the streets near Church of St Mary, water on an older roof tends to find its way in at the lead, the valleys or the chimney. Living close to Riverside Walk is pleasant, but mature trees mean leaves in gutters and valleys each autumn.

Tips from our surveys
There’s plenty you can do without going near the roof. What helps most:
- Don’t climb onto the roof to look
- Keep a photo record of the damp patch
- Check whether pipes or tanks run near the stain
- Record whether it leaks in every downpour or only some
With the Standard Survey you get a follow-up consultation, while Premium includes one in person. It’s a chance to ask about anything in the report.
Have leaves and moss cleared from gutters, valleys and outlets, ideally once the leaves have fallen. Blocked outlets on parapet and flat roofs cause many leaks. Use a professional rather than climbing up yourself.
Roof by roof
Lead flashings
Some roofs have mortar where you’d expect lead. They crack as the roof and wall move, letting rain run behind the joint.
Parapet and box gutters
Linings, joints and outlets are inspected wherever it’s safe.
Landlord and commercial surveys in Thorpe Green
Letting agents can arrange access with tenants, at a time agreed beforehand. Surveys run seven days a week, which can make access easier.
Buyers’ agents can book surveys on behalf of their clients. The report is emailed, so it can go straight to your client.
What we do, step by step
You don’t need to do much on the day. Point out anything you’ve noticed, such as stains, drips or loose pieces, and we’ll get on with the inspection. The survey itself takes about 1–2 hours at most homes, though large, tall or awkward roofs take more time. Older rural homes like those around Thorpe Green can have a main roof, lower lean-to roofs and outbuildings all joined together. Each part is looked at from wherever it can safely be seen.
- You tell us where the water shows and when it appears.
- We check the stain, the ceiling and the loft above it.
- Outside, we check every likely route in.
- We use moisture detection, and thermal imaging where it is useful.
- We email a report with photographs, the likely entry point and recommendations.
Preparing for the visit
- Point out any leaks or damp patches
- Unlock side gates and any roof access doors
- Agree roof access with the managing agent if it’s shared

FAQs for Thorpe Green
How do I find out if my home in Thorpe Green is listed?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Do you cover Thorpe Green?
We do. The survey and report are the same in Thorpe Green as anywhere else.
Is it a structural engineer’s report?
No. We’re experienced roof surveyors, and visible signs like sagging are noted, but calculations and an engineer’s opinion are outside what we do. The report will say if you need an engineer.
Is it the same as a RICS Level 2 or Level 3 survey?
No. It is a specialist roof survey, not a RICS Level 2 or Level 3 building survey. It focuses on the roof and can sit alongside a RICS survey.
Will you go up on the roof?
Only when it’s safe. Safe viewpoints, the roof space and a drone where it applies cover most of what’s needed.
I live in a flat. Can you survey the roof?
Yes, once access has been agreed. Roofs over flats are often shared, so whoever owns or manages the building needs to agree access. We inspect only the parts we are allowed to reach.
Why is not the leak directly above the stain?
Because water travels. It can follow a timber or the underlay a long way first, so the stain may be some distance from where it gets in. That is why we trace the route rather than patching above the stain.
What this survey can’t tell you
A survey is a proper look at the leaking roof, but it cannot do everything. The main limits are:
- Carrying out the fix
- Water from pipes, tanks or heating systems
- What’s under the covering or behind the plaster
