What we are asked to look at in Willesden Green
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. On slate roofs, slipping is often caused by corroded nails.
Look out for signs like these:
- Leaks below a flat extension roof
- Water marks that spread in wet weather
- Damp walls below an overflowing gutter
- Damp underlay across a wide area
For site and facilities teams at buildings such as Donnington Primary School, water through a big roof can travel a long way before it drips, so the search covers more than the obvious spot.
Before you book any roof surveyor
- Their drone registration, if they fly one
- Which parts of the roof they’ll actually see
- Will the report include photos?
- Whether VAT is added on top
Roof leak investigation in Willesden Green
On a flat roof, water can travel a long way under the covering. Splits, blisters, failed laps, worn upstands and blocked outlets are common causes. Standing water puts extra pressure on every weak point. We check both the covering and the room underneath. Leaks under flat extension, garage and dormer roofs are common. An ageing felt roof is a frequent culprit. We’re often asked to look into staining where a gutter or parapet meets the wall and leaks at a dormer or roof window, on chimney stacks, rooflights and dormers and lead flashings.
London’s Victorian and Edwardian roofs have often been repaired many times, so a new leak can be the latest sign of wear rather than a single event. Telling wear from a one-off event matters, because insurers typically exclude wear and tear. That’s as true in Willesden Green as anywhere in London. Photographs and a written account give you something specific to show an insurer, a landlord or a roofer.
We keep jargon out of it: if work is needed, the report says so clearly, and where it can wait, that is said too.

What we do, step by step
We photograph the roof as we go, so you can see in the report what we found and where. We take close-ups from wherever is safe, including by drone where it’s applicable and the weather allows. A typical visit takes about one to two hours at a typical home, while a commercial roof takes nearer three to four hours. In a London area like Willesden Green, the main things to sort out are parking and access: let us know about permits, visitor bays or off-street space, which floor the property is on and how to get into the loft. On the day, the roof is looked at from ground level, from windows, from inside the roof space and from the roof where it’s safe.
- You tell us where the water appears, when, and what the weather was doing.
- Inside, we check the stain and the ceiling around it.
- In the loft, we follow any signs of water back towards the roof.
- We inspect the likely entry points outside, from ground level, windows and the roof where safe.
- We email a written report showing where the water most likely gets in.
Getting ready for the survey
- Jot down any questions you want answered
- Have any paperwork from past roof work to hand
- Clear the way to the loft hatch

Willesden Green questions
Can parking be tricky for a visit in Willesden Green?
Normally it is manageable with a little notice. Let us know what parking is available nearby, and the visit is planned around it.
Do you carry out roof surveys in Willesden Green?
Yes. We survey roofs across London and the South East, and Willesden Green is part of that. Just call 07833 053749 or drop us an email and let us know about the property, and we will talk through which survey suits.
Does the report include photographs?
Yes. Photos are part of every report, so you can see each point for yourself.
What’s the best way to book?
It is easiest to call 07833 053749 or send us an email. Give us the address and some details about the roof. We survey on weekdays, Saturdays and Sundays.
Is this an asbestos survey?
No. We can flag materials that might contain asbestos, but only a specialist asbestos surveyor can confirm it. Buildings built or refurbished before 2000 may contain it.
Will you fix the leak as part of this?
The investigation is about finding the cause. The repair is not part of it. The report shows where the water gets in and what should be done.
How long does the visit take?
The visit normally takes roughly 1–2 hours at a typical home, and about three to four hours for a commercial roof. We’ll confirm what to expect when we arrange the visit.
Tips from our surveys
You do not need to be a roofer to help. Here’s what helps most:
- Take dated photos of the leak
- Stay off ladders and the roof
- Mention any plumbing above the damp area
- Note the weather when the leak shows
If condensation is the cause, we explain it, with recommendations on ventilation. That avoids roof work that wouldn’t help.
Have flashings and flat roofs looked at every few years. They’re where most leaks start, and catching wear early keeps water out.

What else we do in Willesden Green
Should I look at the roof myself first?
Your own check is a good start, but it is not a survey. You will not see flashings, valleys or the backs of chimneys properly from the ground.
During heavy rain, look at the gutters from ground level or a window. Overflowing water can be a sign of a blockage or a gutter that has dropped.
Willesden Green roofs and the weather
About 2.5 miles north-east lies Fenton House, a reminder of how long the area around Willesden Green has been built on. Older roofs in the wider area can hide decades of patch repairs, so the detail matters. In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. If your home in Willesden Green is one of them, bay roofs, hips and later dormers each have their own details. Knowing the roof type helps narrow down where water may be getting in.
If you live in an older home near Church of St Andrew, the leak may come from a chimney, a valley or tired lead rather than the covering itself. If you live near a park such as Roundwood Park, or anywhere with mature trees, autumn leaves can block gutters and valleys, so outlets and downpipes are worth watching.

- Whether rotten timbers meet design loads
- Leaks from plumbing, tanks or pipework rather than the roof
- Faults hidden behind ceilings or boarding
