Roof leak investigation in Old Malden
On a flat roof, water can travel a long way under the covering. Common causes are splits and blisters, tired upstands and outlets that do not drain. Standing water puts extra pressure on every weak point. We check both the covering and the room underneath to narrow it down. Leaks under flat extension, garage and dormer roofs are common. Felt often lasts around 15 to 20 years, so age is part of the picture. Typical surveys look at water marks that spread in wet weather and leaks that appear only in driving rain, across lead flashings, rooflights and dormers and slate and tile slopes.
Houses in smaller places like Old Malden can stand more in the open, where driving rain gets into any gap at a ridge, verge or flashing. A leak that only appears in certain weather frequently points to an exposed detail. It is useful to know when and where the water appears. Gutters and downpipes on the exposed side are worth a look as well.
Pictures do a lot of the work in our reports, so you can see each defect rather than just read about it. If something couldn’t be seen safely, the report is clear about it.

Useful tips for Old Malden property owners
Some practical points come up on survey after survey. They apply to most roofs:
- Do not climb onto the roof to look
- Keep a photo record of the damp patch
- Write down the wind direction and rain when it leaks
- Tell us about any past repairs to the roof
If there are several possible sources, we list them in order of likelihood. We say which items need prompt attention, so you know what to deal with first.
Plan a roof survey every few years. Flashings, valleys and flat roof details are frequent weak points, and catching wear early keeps water out.
What this survey cannot tell you
It’s a careful look at the leaking roof, not the whole story. Its limits include:
- What’s under the covering or behind the plaster
- Carrying out the fix
- Structural calculations (that’s a structural engineer’s job)
If you’re not sure which survey you need, ring 07833 053749 or email us and we will give you a straight answer before booking. What a survey covers and does not.

Wind, rain and roofs in Old Malden
Older houses across Surrey often have handmade clay tiles, and many have tile-hanging. Horsham stone slab roofs survive on some old buildings in Surrey. The covering and its details give the first clues when tracing where water is coming from. About 1.8 miles south-east lies Fitznells Manor, a reminder of how long the area around Old Malden has been built on. If yours is one of the older homes, expect a mix of original materials and later repairs on the roof, and any change of roofing material on a listed home needs checking with the council first.
Trees in and around Hogsmill LNR shed leaves that can end up in nearby gutters, and an overflowing gutter soon means a wet wall. Landlords with a home close to Tolworth station may find that finding the cause of a leak fast keeps a tenant’s home dry and the work focused.
Old Malden is about 2 miles north-west of Ewell, in Surrey. If you’re in Old Malden, booking works exactly as it does anywhere else: a call or an email, a price, then a date. Across Surrey, we cover Old Malden. For surveys nearby, see our London page.

What we do, step by step
Before we start, tell us why you’ve booked: a purchase, a leak, a storm, new work or simply peace of mind. That way we can focus on what matters to you. The visit normally takes roughly 1–2 hours for most houses; commercial roofs usually need 3–4 hours. With a bit of garden around a house, as there often is around Old Malden, the roof can be viewed from several angles. Mention any side of the property we cannot get to. The loft, where there’s safe access, completes the picture.
- You get in touch with details of the leak and any photos.
- Inside, we check the damp area and the loft space above it.
- Likely entry points outside are checked, from flashings and valleys to gutters and outlets.
- Moisture readings and thermal imaging are used where they help.
- We email a report with photos, the likely entry point and recommendations.
Before the survey
- Let us know about parking near the property
- Gather any invoices or paperwork from past roof work
- Keep pets in another room
Booking a survey
Photos help, if you have them. Take them safely from the ground or a window, and please don’t climb up for a closer look. To get started, ring 07833 053749 or drop us an email.
Advice
DIY checks: what’s safe
Keep a simple record: dates of leaks, photos from ground level and any work done on the roof. Send it with your enquiry.
You can learn a lot from ground level. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Never climb onto the roof to look.
Signs you need a roof leak investigation in Old Malden
Slipped or missing slates and tiles let rain reach the underlay. Ageing felt underlay eventually tears and lets water through, and very old roofs may have no underlay at all. Corroded nails, known as ‘nail fatigue’, are a frequent cause on slate roofs.
Signs worth acting on include:
- Brown rings on upstairs ceilings
- Damp patches next to the stack
- Damp ceilings under a flat roof
- Water that shows only in certain storms
Shop and office owners around Bentall Centre may find that a quick answer on where water is coming in keeps a business running.

What we look for on each type of roof
Chimney stacks
Damp on a chimney breast inside frequently starts at the top of the stack. Open, unused pots let rain fall down the flue.
Slate and tile slopes
On slate roofs, corroded nails let slates slip. Even a single gap can let water in, especially in driving rain.

Old Malden questions
Do you carry out roof surveys in Old Malden?
Yes, Old Malden is one of the places we work. Every survey there gets the same written report with photos, and visits run on weekdays and weekends.
Will you come out to Old Malden?
We do. A small place gets exactly the same survey as a big one, with the route planned beforehand.
Do I need to be at home?
Not always. If we only need the outside, we can agree that ahead of time, but anything inside needs someone there to give access.
Is it the same as a RICS Level 2 or Level 3 survey?
No. Our survey is a roof survey, not a RICS Level 2 or Level 3 survey of the whole building. It focuses on the roof and can sit alongside a RICS survey.
What do I do with the report?
The report arrives by email. The Standard Survey includes a follow-up consultation, and the Premium Survey an in-person consultation.
Do you need to get into the loft?
If it is needed and safe to reach, yes. We look for staining, damp, daylight and signs of movement, as far as the space allows.
How much does a roof leak investigation cost in Old Malden?
Our price is from £150, including VAT. What you pay for your roof depends on its size, height, access and the package.
