Roof leak investigation in Park Royal: what you get
We investigate roof leaks in Park Royal 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 ring 07833 053749 or email us. If you’ve noticed damp underlay across a wide area and a leak that comes and goes with the weather, a survey will tell you what’s going on, whatever the roof.
Many London homes are well over a century old and their roofs have been patched more than once, so a new leak can be the latest sign of wear rather than a single event. Insurers typically exclude wear and tear, so it’s useful to know whether damage is old or new. That is as true in Park Royal as anywhere in London. Photos and a written account give you something specific to show an insurer, a landlord or a roofer.
How fast the report arrives depends on the package: the Basic Survey within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey on the same day.

Roof leak investigations around Park Royal
About 2 miles south-west lies Pitzhanger Manor, a reminder of how long the area around Park Royal has been built on. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and any change of roofing material on a listed home needs checking with the council first. Outer London has plenty of Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, often with hipped roofs in clay or concrete tiles. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Different coverings let water in at different points, which shapes where the search starts.
Shop and office owners around London Designer Outlet may find that a leak can close part of a shop or office, so finding the cause quickly matters. Take a building like West Twyford 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, lead flashings, valleys and old chimneys are typical places for water to get in.
Park Royal is about 1 mile south-west of Harlesden, in Greater London. If you are in Park Royal, booking works exactly as it does anywhere else: a call or an email, a price, then a date.

Park Royal questions
Does a conservation area affect roof work in Park Royal?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you’re planning to re-roof in a different material.
Do you carry out roof surveys in Park Royal?
We do. Every survey there gets the same written report with photographs, and visits run on weekdays and weekends.
Do you use thermal imaging to find leaks?
Thermal imaging is used where it’s useful, and it is part of the Premium Survey. It picks up temperature patterns rather than water, so anything it suggests is checked with moisture readings.
Will you fly a drone over my roof?
Where it helps and the rules allow, yes. Our sub-250g drone is flown by a CAA-registered operator with a Flyer ID and Operator ID, and the airspace and weather are checked before every flight.
Do you carry professional indemnity insurance?
Our cover is professional indemnity plus public liability, and we can provide details if a managing agent needs them.
What’s the best way to book?
Simply call 07833 053749 or send us an email with the address. After a few questions, we confirm the price and fix a day, weekday or weekend.
How do you tell a leak from condensation?
Condensation can look very like a leak. Widespread damp on the underside of the roof in cold weather, with blocked vents, suggests condensation. We check the pattern of damp and the ventilation, then say which is most likely.
Leave it or get it looked at?
Water damage grows the longer it’s left. Wet timbers start to decay, plaster softens and insulation stops working. Finding the source early keeps the damage down. In a London terrace or conversion, a roof defect rarely stays your problem alone: failed flashings and blocked valley gutters can send water into more than one home. Dealing with it early is far less disruptive.
One thing that affects the price is the package: from £150 for Basic, £250 for Standard and £400 for Premium, inc. VAT. The roof’s size, height and access matter as well.

Checking the roof from ground level
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Share it with us when booking and it will help the survey.
A DIY look is useful, but it isn’t a survey. You won’t see flashings, valleys or the backs of chimneys properly from the ground.
Honest limits
It’s a careful look at the leaking roof, not the whole story. Its limits include:
- Whether rotten timbers meet design loads
- Leaks that only appear in weather we cannot recreate
- Defects hidden under coverings or inside walls without opening up
Not sure which survey suits your roof? You can phone 07833 053749 or send us an email and we will tell you before booking. What our survey covers.

Landlord and commercial surveys in Park Royal
Landlords, agents and building managers in Park Royal and across Greater London can book any of our surveys. To discuss a property or a block, ring 07833 053749 or send us an email.
A roof problem in a let property affects your tenants as well as the building. A survey shows what needs attention, so you can plan the work.
The survey, step by step
Every roof is different, but as a rough guide the survey takes an hour or two, more where the leak is intermittent or the roof is large. If you have questions on the day, just ask. In converted houses and mansion blocks, the loft hatch is often on a shared landing. If that applies to your building, it is useful to agree access with the neighbours or the managing agent first. Everything else is planned around the building, not the postcode.
- We start with your notes and photos of the leak.
- We examine the damp area and the rooms near it.
- From the roof space, we trace the water’s route where there is safe access.
- 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.
Getting ready for the survey
- Keep pets out of the way during the survey
- Dig out any old roof reports or invoices
- Move anything stored under the loft hatch

Tips from our surveys
Here are a few things we’d tell any owner:
- Check the loft is accessible
- Leave roof access to professionals
- Do not touch fittings that water is reaching
- Catch drips in a bucket and protect the floor
Once the work is done, hold on to the report. If the leak returns, it’s a useful record of what was found, which makes the next step quicker.
Look at the roof from the ground after strong winds. Pieces of slate or tile in the garden mean something has moved. Small faults dealt with quickly rarely become leaks.
