About our roof leak investigation in Sudbury
We investigate roof leaks in Sudbury and across London and the South East. Surveys are carried out on weekdays and at weekends. We look inside and out, at flashings, valleys, chimneys, gutters and flat roof details. The findings come in a written report with photos. If it is leaking right now, contain the water and keep it clear of electrics, and then call 07833 053749 or email us. If you are worried about leaks that appear only in driving rain and damp ceilings under a flat roof, a survey will tell you what’s going on, whatever the roof.
In London, leaks often start somewhere hidden: a butterfly roof’s central valley gutter, a parapet gutter, a chimney flashing or a flat roof over a back addition. For a leak or storm damage in Sudbury, those hidden details are where the inspection begins. A hidden gutter that overflows can send water a long way before it shows.
Where we cannot see part of the leaking roof, the report says so. That way, it is clear what was covered and what wasn’t, and what we’d suggest next.

Why act early in Sudbury
Damp in a ceiling or loft can lead to mould. Once mould takes hold, it’s harder to clear. Finding the leak comes first. Work on a London roof is rarely simple to arrange, with parking, neighbours and access all to think about. Knowing what’s needed early gives you time to plan it calmly, rather than in a rush after a leak.
Prices start from £150, including VAT. Packages run from Basic at £150 through Standard at £250 to Premium at £400, with VAT included, and we’ll tell you which fits.

What we cannot see
In fairness, there are limits to any roof survey:
- Plumbing leaks that look like roof leaks
- What’s under the covering or behind the plaster
- Carrying out the fix
If in doubt, call 07833 053749 or drop us an email and we will suggest the right survey before booking. What a survey covers and doesn’t.
Roof types and parts we check
- Flat roof details
- Slate and tile slopes
- Chimney stacks
- Lead flashings
- Rooflights and dormers
- Valleys and parapet gutters
- The roof space
Different roofs, different checks
Slate and tile slopes
‘Nail fatigue’ is a common cause of slipped slates. One slipped slate can be enough to cause a leak.
Flat roof upstands and outlets
Flat roof water can travel under the covering before it shows. Moisture readings and thermal imaging can help narrow it down where conditions suit.
When to book a survey in Sudbury
Chimneys can let water in by several routes. Eroded pointing, cracked flaunching, failed flashings and open pots can all be responsible. It can show up on the chimney breast, nearby ceilings or in the roof space.
Common reasons to book include:
- Damp ceilings under a flat roof
- Damp underlay across a wide area
- Water dripping from rafters or underlay
- Leaks that appear only in driving rain
Shop and office owners around London Designer Outlet may find that water through a ceiling can damage stock and close a sales floor, so the source needs finding fast.
Choosing a roof surveyor
- How they’ll see the roof: from the ground, the loft, the roof or by drone
- Whether the loft is part of the inspection
- What the report includes, and whether it has photos
- What’s outside the scope of the survey
What happens on the day
The visit has one job: to look at the leaking roof as closely as is safe and record what we find. Everything we note and photograph goes into the written report. It normally takes between one and two hours for most homes, though a hard-to-trace leak can take longer. Many London properties are flats or terraces with no side access, so the back of the roof is often seen from upstairs windows, from inside or, where a flight is allowed, from the air. If the building has a managing agent or access rules, let us know when you book.
- We help you choose the package that suits the leak.
- We agree a date, including weekends.
- The investigation works from the stain back to the roof.
- Where it is useful and included, we take moisture readings and use thermal imaging.
- You get photos, the likely cause and clear recommendations.
Before we arrive
- Keep pets in another room
- If the roof is shared, arrange access with whoever manages the building
- Have any questions written down, so nothing gets missed
Arrange a survey
A quick phone call is usually the easiest start: call 07833 053749 or send us an email and we’ll ask a few questions about the roof. The price is agreed before a date is set.

Leaks and storm damage in Sudbury
The wider area around Sudbury has a long history of building, with Northolt Manor about 2.2 miles west. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and a listed home or one in a conservation area may need consent for changes of material. Further from the centre, London’s housing takes in interwar semis with hipped roofs in clay or concrete tiles as well as slate-roofed terraces. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. Knowing the roof type helps narrow down where water may be getting in.
Anyone responsible for a site like Sudbury Primary School will know that tracing a leak on a big roof starts with where the water appears and works back. Homes near green spaces such as Preston Park can get more leaves in their gutters in autumn, and an overflowing gutter soon means a wet wall.

Your questions about roof leak investigations in Sudbury
Is parking a problem for a survey in Sudbury?
It rarely stops a survey, but it is worth planning. Let us know the parking rules on your street and we’ll work around them.
Is Sudbury in the area you cover?
We do. The survey and report are the same in Sudbury as anywhere else.
Can you tell me if my roof has asbestos?
No. We can flag materials that might contain asbestos, but confirming it is a job for a specialist asbestos surveyor. Buildings built or refurbished before 2000 may contain it.
How soon will I get the report?
Each package has its own report time. Basic is within 48 hours, Standard is 24–48 hours and Premium is the same day. If you have a deadline, such as an exchange date, tell us as you book.
Will you walk on the roof?
Only where it is safe to do so. We look at 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 it applies. The report says if anything couldn’t be seen.
How long does a roof leak investigation take?
It normally takes about 1–2 hours for most homes, though a hard-to-trace leak can take longer. Report times depend on the package.
Is the repair included in the leak investigation?
The investigation is about finding the cause. The repair is not part of it. You get a report with photos showing where the water is getting in and what needs attention.
