How a roof leak investigation works in Cranbrook
Leaks tend to begin where one part of a roof meets another. Flashings at chimneys and walls, valleys, gutters, parapets and flat roof upstands and outlets are the usual suspects. Each of these is checked in turn and we follow where the evidence leads. Every chimney, dormer and roof light adds more joints to check. Each one is checked from wherever it is safe to see it. If you’re worried about drips in the loft during heavy rain and water that shows only in certain storms, a survey will tell you what’s going on, whatever the roof.
In a London flat, water can travel some way before it shows. Tracing it back matters, both for dealing with the cause and for any insurance claim. We look at what we are given access to in Cranbrook, inside and out. Tell us when the water shows, and in what kind of weather.
It is not only a list of defects. For each finding, it explains what it is, why it matters and what we’d recommend, so you can decide what to do next.

When to book a survey in Cranbrook
Flat roofs fail with age and wear. A felt roof often lasts around 15 to 20 years, and splits, blisters and lifting laps let water in. Leaks frequently start at the edges, upstands and outlets.
Things that often lead to a survey include:
- Water marks that spread in wet weather
- Staining around the chimney inside
- Drips from nail tips in a cold loft
- Wet patches high on an inside wall
Homes near green spaces such as Valentines Park can get more leaves in their gutters in autumn, and blocked gutters overflow and soak walls.
Before you book anyone
- How long they’ve been surveying roofs
- Whether the loft is part of the inspection
- Whether the price includes VAT
- Do they have a CAA Flyer ID and Operator ID for drone work?
Surveys for landlords and agents in Cranbrook
We survey roofs for landlords and letting agents as well as householders. A written report with photos gives you a clear record of the leaking roof.
Shared roofs need a little more planning: access has to be agreed with whoever owns or manages the building. Let us know about it as you book and we’ll plan the survey around it.
Practical tips
Some practical points come up on survey after survey. They apply to most roofs:
- Mention earlier attempts to fix the leak
- Catch drips in a bucket and protect the floor
- Keep a photo record of the damp patch
- Stay off ladders and the roof
With the Standard Survey you get a follow-up consultation, while Premium includes one in person. It is a chance to ask about anything in the report.
Have flashings and flat roofs looked at every few years. Flashings, valleys and flat roof details are frequent weak points, and catching wear early keeps water out.
How we price roof leak investigations
We confirm the exact price before booking. These are the things that affect it:
- How big the roof is
- The use of thermal imaging or a drone
- The type of building, from a house to a block or an office
- Extensions, dormers and garages with roofs of their own
All our prices include VAT. Our price is from £150, including VAT. You will know the price for your roof before you book.
Booking your survey
To price your survey accurately, we’ll ask about:
- Where water is showing inside, if it is
- Why you want a survey: buying, a leak, a storm or new work
- The address and postcode of the property
- How the loft is reached, if there is one
A quick phone call is typically the easiest start: phone 07833 053749 or drop us an email, and we will ask about the building and what you need. The price is agreed before a date is set.
Common questions in Cranbrook
Is parking a problem for a survey in Cranbrook?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly.
Does a conservation area affect roof work in Cranbrook?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
How experienced are you?
We have more than 20 years’ experience and have completed over 5,000 surveys.
Can a leak be traced on a dry day?
In many cases, yes. Stains, tide marks, damp timbers and moisture readings typically point the way. Some leaks only show in particular weather, so photos and notes from when it leaks help a lot.
Do you use thermal imaging to find leaks?
We use thermal imaging where it helps, and it’s part of the Premium Survey. It shows temperature differences, not water itself, so anything it suggests is checked with moisture readings.
Do you look in the roof space?
If the survey needs it and the roof space can be reached safely, yes. Please clear anything stored under the hatch, and if the loft cannot be reached safely, the report says so.
How much is a survey?
Our price is from £150, including VAT. We confirm the price for your roof before you book. To get a price, ring 07833 053749 or email us.

Roof leak investigations in Cranbrook: local notes
Historic houses such as Valentines Mansion, about 0.5 miles north, show how far back building in the area around Cranbrook goes. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and the council can say whether a home is in a conservation area. Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, frequently with hipped roofs of 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.
Anyone responsible for a site like The Ursuline Academy Ilford will know that a leak through a large roof is often found some distance from where the water shows inside. For landlords with property near Ilford station, finding the cause of a leak fast keeps a tenant’s home dry and the work focused.

- Plumbing leaks that look like roof leaks
- Putting the leak right
Not sure which survey suits your roof? You can call 07833 053749 or email us and we’ll tell you. The full list of what we check.
What we check
- Chimney stacks
- Lead flashings
- The roof space
- Slate and tile slopes
- Rooflights and dormers
- Flat roof details
- Valleys and parapet gutters
What we do, step by step
After the inspection, everything we found is written up as a written report with photographs, emailed to you. On timing, it normally takes between one and two hours for most homes, though a hard-to-trace leak can take longer. In converted houses and mansion blocks, the loft hatch is often on a shared landing. If that applies to your building, it’s useful to agree access with the neighbours or the managing agent first. Otherwise, the visit in Cranbrook runs like any other.
- You pick a Basic, Standard or Premium Survey.
- We agree a date, including weekends.
- The investigation works from the stain back to the roof.
- Where it’s useful and included, we take moisture readings and use thermal imaging.
- The report explains the likely entry point and what needs attention.
Before we arrive
- Keep pets out of the way during the survey
- Let us know about parking before the day
- Show us where any leaks or stains appear
