Roof leak investigation in Gadebridge
We use moisture detection and thermal imaging where they help. Moisture readings show which materials are wet. A thermal camera shows patterns of temperature rather than water, so we confirm what it suggests 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. We survey rooflights and dormers, lead flashings and valleys and parapet gutters, and common reasons people get in touch are drips in the loft during heavy rain and damp walls below an overflowing gutter.
Around Gadebridge, chimneys on older homes are a common source of leaks, through worn flaunching, failed pointing or lifted flashings. Damp in a chimney breast can have more than one cause, so it isn’t always obvious where it starts. It is worth looking at the stack from outside and at the timbers beside it in the loft.
Most points in the report come with a picture, so you can see each defect rather than just read about it. If something couldn’t be seen safely, the report is clear about it.

Your questions about roof leak investigations in Gadebridge
Will you come out to Gadebridge?
Yes, Gadebridge is covered. We survey roofs across London and South East England, from towns to the smallest villages. Longer journeys are simply planned ahead of time.
Are flat-roofed garages and porches in Gadebridge worth including?
Yes, if you’d like it included, mention it as you book. Cement sheet roofs on buildings from before 2000 may contain asbestos, so a specialist asbestos surveyor should check before they’re disturbed.
Do you use drones?
Yes, where it is applicable. We hold a CAA Flyer ID and Operator ID and fly a drone under 250g, and every flight depends on the airspace and the weather.
How long does the visit take?
Allow about one to two hours, more where the leak is intermittent or the roof is large. We’ll give you an idea of timing as you book.
How should I prepare for the leak investigation?
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 you carry professional indemnity insurance?
We hold professional indemnity and public liability insurance.
Can you find a leak when it isn’t raining?
In many cases, yes. Leaks leave clues, such as staining, damp timber and moisture in materials. Some leaks only show in particular weather, so photos and notes from when it leaks help a lot.

Practical tips
Some practical points come up on survey after survey. They’re worth knowing whatever the roof:
- Do not climb onto the roof to look
- Mention any plumbing above the damp area
- Keep water away from lights and sockets
- Move stored items away from the hatch
If condensation is the cause, we explain it, and suggest how the roof space could be better ventilated. It saves chasing a leak that isn’t there.
Keep gutters, valleys and outlets clear, ideally once the leaves have fallen. Blocked outlets on parapet and flat roofs cause many leaks. Use a professional rather than climbing up yourself.
How we price roof leak investigations
What a survey costs depends on the time and equipment it needs. The main factors are:
- Whether you choose the Basic, Standard or Premium Survey
- Commercial roofs and larger buildings
- Features like valleys, chimneys, dormers and parapets
- Whether thermal imaging or a drone is needed
A Basic Survey starts from £150, including VAT. The Standard Survey starts from £250 and the Premium Survey from £400. You will know the price for your roof before booking.
Booking your survey
If you can, have these to hand when you get in touch:
- Your postcode, so we can check access and travel
- Any photos you have, taken from the ground or a window
- When you need the report by
- Where water is showing inside, if it is
Most bookings start with a short call: call 07833 053749 or email us and we’ll ask a few questions about the roof. You’ll have a price before anything is arranged.
Roof by roof
Flat roof upstands and outlets
The upturned edge of a flat roof covering keeps water out at walls. A low or cracked upstand is a common way in.
Chimney stacks
We check the outside of the stack and the breast inside, not a flue, gas or sweep inspection.
The survey, step by step
We look at the roof from outside and, where it’s relevant and there is safe access, from inside the roof space too. In the loft, the signs we look for are staining, damp, daylight and sagging. The whole visit typically takes about one to two hours for most homes, though a hard-to-trace leak can take longer. Some parts of a survey depend on the weather, so a visit to Gadebridge is booked with the forecast in mind: the parts that need calm, dry weather are planned around it.
- We start with your notes and photos of the leak.
- Inside, we look at 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 the ground, windows and the roof where safe.
- You receive a report with the likely source, photos and recommendations.
Preparing for the visit
- Gather any invoices or paperwork from past roof work
- Leave side gates unlocked
- For flats, make sure roof access has been agreed

Advice
What a roof leak investigation looks like in Gadebridge
Listing and conservation areas can both shape what roof work is allowed on an older home. Your council and Historic England’s list will tell you where you stand, ideally before any re-roofing is planned. Hemel Hempstead, which Gadebridge is part of, is one of England’s post-war new towns. Many homes in the new towns date from the post-war decades, with concrete interlocking tiles, low-pitched roofs and flat-roofed garages and porches. Low pitches let wind-driven rain reach further under the tiles, and flat-roofed garages and porches are common leak points.
If you live near a park such as Gadebridge Park, or anywhere with mature trees, autumn leaves can block gutters and valleys, and blocked gutters overflow and soak walls. The streets around a church such as St Alban's Church are frequently among the oldest in a place, and if your house is among the older ones nearby, the leak may come from a chimney, a valley or tired lead rather than the covering itself. If you let a flat or house near Hemel Hempstead station, a tenant living with a leak needs the cause found, not just the stain painted over.

Surveys for landlords and agents in Gadebridge
Freeholders and residents’ companies use a roof report to plan and budget.
Letting agents can arrange access with tenants. Surveys run seven days a week, which can make access easier.
Should I look at the roof myself first?
Fresh stains on ceilings or walls after rain are worth noting. Take a photo and write down when you saw it, which helps when we check the roof.
After strong wind, take a look from the pavement or garden: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Leave anything above ground level to a survey.
