When you need someone else
A survey is a proper look at the leaking roof, but it cannot do everything. The main limits are:
- Leaks that only appear in weather we can’t recreate
- A structural engineer’s report
- Defects hidden under coverings or inside walls without opening up
If in doubt, ring 07833 053749 or email us and we’ll suggest the right survey. What our survey covers.
Roof types and parts we check
- Valleys and parapet gutters
- Chimney stacks
- Slate and tile slopes
- Flat roof details
- Lead flashings
- The roof space
- Rooflights and dormers
Roof leak investigation in Cricklewood
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 its findings are checked with moisture readings. Moisture detection is included in the Standard Survey, and thermal imaging in Premium. The best thermal results come after a sunny day, with a dry roof and little wind. Common reasons to book are damp ceilings under a flat roof and water coming in around a roof light or dormer, across slate and tile slopes, flat roof details and the roof space.
In converted houses and blocks across London, water from a roof can run a long way before it shows on a ceiling, sometimes in a different flat from the one below the defect. That makes the source hard to pin down, and finding it matters for whoever has to deal with it. In Cricklewood, we inspect what we can reach safely and are given access to. Let us know when the water shows, and in what kind of weather.
The Standard Survey adds moisture detection, a structural check and a follow-up consultation. The Premium Survey adds thermal imaging, drone inspection where it applies, structural analysis and an in-person consultation.

What we look for on each type of roof
Lead flashings
Some roofs have mortar where you’d expect lead. Fillets crack and pull away over time, and water runs down behind them.
Slate and tile slopes
‘Nail fatigue’ is a common cause of slipped slates. Even a single gap can let water in.
Why act early in Cricklewood
Damp in a ceiling or loft can lead to mould. Once mould takes hold, it is harder to clear. Stopping the water is the first step. 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.

Your questions about roof leak investigations in Cricklewood
Do you cover Cricklewood?
Yes. Our area covers London and the South East, and Cricklewood is part of that. You can call 07833 053749 or use the contact form with the address and some details.
Will parking be an issue for a roof survey in Cricklewood?
It depends on the street. If Cricklewood has controlled parking where you are, a visitor permit is the easiest answer, and a driveway is even better.
Will you go up on the roof?
Only if it is safe. We check 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. Anything we can’t see is noted in the report.
What’s in the report?
You get our findings in writing, part by part, with photos, and ends with what we recommend. Points are put with the most urgent first where relevant.
How do I arrange a roof leak investigation in Cricklewood?
Just ring 07833 053749 or email us with the address. We will ask a few questions, confirm the price and agree a date, weekday or weekend.
How experienced are you?
We have more than 20 years’ experience and have completed over 5,000 surveys.
Can every leak be traced?
Not every leak can be pinned down in a single visit. Most leave clues we can follow, but intermittent leaks that need particular weather can be harder. We report what we found and the likeliest sources.
DIY checks: what’s safe
After heavy rain, check ceilings and the tops of walls for new stains. Photograph them and note the date.
Watch the gutters in a downpour, from a window or the ground. Overflowing water can be a sign of a blockage or a gutter that has dropped.
How the survey works
Time on site depends on the size and shape of the roof, but as a rough guide the survey takes about one to two hours for a house, and longer for a large or complex roof. You are welcome to ask questions while we’re there. Surveys in Cricklewood can be booked for any day of the week. London parking is frequently by permit or pay-and-display, so it helps to know what’s near you, and to clear a path to the loft hatch. A back bedroom window can be the best vantage point for a rear addition, so we may ask to use one.
- You let us know where the water appears, when, and what the weather was doing.
- We examine the damp area and the rooms near it.
- In the loft, we follow any signs of water back towards the roof.
- We inspect the likely entry points outside, from the ground, windows and the roof where safe.
- You receive a report with the likely source, photos and recommendations.
Preparing for the visit
- If the roof is shared, arrange access with whoever manages the building
- Show us where any leaks or stains appear
- Clear the way to the loft hatch

Wind, rain and roofs in Cricklewood
Fenton House, about 1.7 miles east, is one of the historic houses in the wider area around Cricklewood. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs. Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of clay or concrete tiles. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Each of these roof types has its own typical places for water to get in.
If you look after a building like Anson Primary School, water through a big roof can travel a long way before it drips, so the search covers more than the obvious spot. If you live in an older home near St Gabriel's Church, leaks on older roofs often start at lead flashings, valleys or around old chimney stacks. For businesses in and around places such as Brent Cross Shopping Centre, a quick answer on where water is coming in keeps a business running.
