Roof leak investigation in Norwood Green, Greater London
Roof leak investigations in Norwood Green and the rest of Greater London. We survey seven days a week.
- Drips from nail tips in a cold loft
- Water coming in around a roof light or dormer
- Water dripping from rafters or underlay
Different roofs, different checks
Slate and tile slopes
Cracked mortar lets ridge and hip tiles move. Water then gets in along the top of the roof.
Lead flashings
Water from a failed flashing can travel down the wall or along a rafter. That is why we check the flashings near a stain, not just the one directly above.
Roof leak investigations for homes and businesses in Norwood Green
Moisture readings and thermal imaging are used where they’re useful. Moisture readings show which materials are wet. Thermal imaging shows temperature differences that can point to wet areas, not water itself, so we confirm what it suggests with moisture readings. Thermal imaging is part of the Premium Survey, and moisture detection comes with Standard. Thermal imaging works best after a sunny day, on a dry roof with little wind. If you’ve noticed damp patches next to the stack and stains around a skylight, a survey will tell you what’s going on, on slate and tile slopes, the roof space and rooflights and dormers alike.
London’s Victorian and Edwardian roofs have frequently been repaired many times, so a new leak can be the latest sign of wear rather than a single event. Insurers typically exclude wear and tear, so it is useful to know whether damage is old or new. A careful look in Norwood Green tells the two apart where the evidence allows. A written record with photographs helps you explain what was found to whoever deals with it next.
Every survey ends with a written report, with photographs, emailed to you. It explains the condition of the leaking roof, the defects we found and what we recommend.

Common roof problems in Norwood Green
Every flat roof covering has a working life. A felt roof often lasts around 15 to 20 years, and as it ages it splits, blisters and opens at the laps. Upstands and outlets are common weak points.
We are often asked to look at:
- Damp underlay across a wide area
- Stains around a skylight
- Ceiling stains that grow after rain
- A leak that comes and goes with the weather
Shop and office owners around Treaty Centre may find that a leak can close part of a shop or office, so finding the cause quickly matters.
What to check before booking
- Whether you get a written report with photos
- What follow-up you get after the report
- Will they check the loft as well as the outside?
- What experience they bring
Before and after the survey
Getting the most from a roof leak investigation starts before we arrive and carries on afterwards. Tips:
- Write down the wind direction and rain when it leaks
- Clear the loft hatch so we can get in
- Keep a photo record of the damp patch
- Have an electrician check any wet fittings
Keep the report after the work is done. If the leak returns, it’s a useful record of what was found.
Check the loft after heavy rain, with care and a good torch. Watch for water marks, wet underlay and damp wood. Take photos of anything that changes.

Roof leak investigations in Norwood Green: local notes
The wider area around Norwood Green has a long history of building, with Osterley House about 0.6 miles south-east. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs. In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Knowing the roof type helps narrow down where water may be getting in.
If you live near a park such as Inwood Park, or anywhere with mature trees, autumn leaves can block gutters and valleys, and an overflowing gutter soon means a wet wall. If you live in an older home near Church of St Mary, leaks on older roofs frequently start at lead flashings, valleys or around old chimney stacks.
Norwood Green is about 1 mile south-east of Southall, in Greater London. We survey roofs in Norwood Green and the rest of Greater London. Norwood Green is one of the towns and villages in Greater London we cover for roof leak investigations. We also survey roofs in London.
We survey roofs across the UB2, TW5 and TW7 postcode area for roof leak investigations and the streets around it.

Why it’s worth a survey now in Norwood Green
A small drip today can be a bigger leak after the next storm. Wind lifts loose slates further and gaps widen. An investigation now gives you time to plan the work. In Norwood Green, as across London, an overflowing gutter soaks the wall below. A blocked outlet ignored for a winter or two can mean damp walls inside.
Every price we give includes VAT, and the report isn’t charged as an extra. Our price is from £150, including VAT. Where your roof sits in the range depends on its size, height and access.
Why us?
- Over 20 years’ experience
- A photo-illustrated written report

FAQs for Norwood Green
Is my home in Norwood Green listed or in a conservation area?
The council and Historic England’s list are the places to check. It is worth checking before planning roof work, as both can affect what’s allowed.
Is Norwood Green in the area you cover?
Yes. We cover the whole of London and South East England, and Norwood Green is part of that. You can ring 07833 053749 or send us an email with the address and a few details, and we’ll talk through which survey suits.
Can every leak be traced?
We can’t promise it. Water can travel a long way, and some leaks only show in particular storms. If we cannot be sure, the report ranks the possible sources.
Does the investigation include the repair?
This service finds and reports the cause, and the repair is separate. The report gives any roofer a clear brief.
What happens next?
The report comes by email, and what you do next is up to you: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
What should I do before you arrive?
Make sure the loft can be reached. Gather any photos and notes about when it leaks, plus details of past repairs. Keep catching drips and keep water away from electrics.
Do I need to be at home?
Not necessarily. An outside-only look can be arranged beforehand, but the loft and any rooms with damp need someone to let us in.
What happens on the day
When we arrive, we start by asking what you’ve noticed and what you need to know. After that, we look at everything we can see safely, from ground level, from windows, in the loft space and by drone where it applies. The survey usually takes about 1–2 hours for most homes, though a hard-to-trace leak can take longer. For a visit in Norwood Green, parking and access are the things to plan: let us know about parking, the floor the property is on, any shared entrance and loft access. On the day, the roof is looked at from the ground, from windows, from inside the loft space and from the roof where it is safe.
- We start with what you’ve seen: where the stain is and when it gets worse.
- The visit starts indoors, at the stain and in the loft.
- Likely entry points outside are checked, from flashings and valleys to gutters and outlets.
- Moisture readings and thermal imaging are used where they help.
- You receive a written report with photos showing the likely source and what needs attention.
Before the survey
- If it is not your property yet, arrange access through the agent
- Move anything stored under the loft hatch
- Point out any leaks or damp patches
