Roof leak investigations around Essendon
Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles, and flat-roofed additions turn up almost everywhere. Knowing the roof type helps narrow down where water may be getting in. The wider area around Essendon has a long history of building, with Hatfield House about 2.4 miles west. If you own one of the older houses, expect a mix of original materials and later repairs on the roof, and a listed home or one in a conservation area may need consent for changes of material.
If you look after a shop, office or commercial unit, for instance near Howard Centre, finding where water is getting in quickly keeps disruption down. If you look after a building such as Essendon CofE (VC) Primary School, tracing a leak on a big roof starts with where the water appears and works back. If you let a flat or house near Bayford station, tracing a leak quickly matters when a tenant is living with it.
Essendon is about 3 miles south-east of Welwyn Garden City, in Hertfordshire. We survey roofs in Essendon and the rest of Hertfordshire, as part of our work across London and South East England.

Roof leak investigation in Essendon
We use moisture detection and thermal imaging where they help. 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. We survey valleys and parapet gutters, lead flashings and chimney stacks, and common reasons people get in touch are leaks that appear only in driving rain and damp ceilings under a flat roof.
Being in a small place like Essendon makes no difference to how a leak or storm damage is looked at: the journey and access are just planned beforehand. Tell us where the water shows, when it appears and anything you’ve noticed outside, plus any earlier repairs. Photos of the stain and of the roof from outside are helpful too.
You can share the report with anyone who needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent, whichever applies.

For landlords and managing agents
If the property is let, the agent or a tenant can let us in, at a time agreed ahead of time. Surveys run on weekdays and at weekends, which can make access easier.
Shared roofs need a little more planning: access has to be agreed with whoever owns or manages the building. Let us know about it when booking and we will plan the visit with that in mind.
What this survey cannot tell you
No survey can tell you everything, and we’d rather be clear about that before you book. Keep these in mind:
- A structural engineer’s report
- Putting the leak right
- Water from pipes, tanks or heating systems

Different roofs, different checks
Parapet and box gutters
Parapet and box gutters sit behind walls or inside the roof. A blocked outlet sends water over the lining and into the building.
Flat roof upstands and outlets
Upstands seal the edge of a flat roof where it meets a wall. A low or cracked upstand is a common way in.
How we price roof leak investigations
Our packages start from £150, with VAT included. The price for your roof depends on:
- Extensions, dormers and garages with roofs of their own
- Roof area
- Whether thermal imaging or a drone is needed
- The height of the building and how the roof can safely be seen
A small, low roof with good viewpoints takes less time than a tall, complicated one, and the package you pick makes a difference too. The price is always agreed first.
Getting in touch
A little information up front helps. Please include:
- Any photos you have, taken from the ground or a window
- Any stains, drips or damp patches you’ve seen indoors
- Any deadline, like an exchange date
- The kind of building and roof involved
Prices start from £150, including VAT. What you pay depends on the roof’s size, access and the package, and you can ring 07833 053749 or use the contact form to find out.
Leave it or get it looked at?
Water and electrics don’t mix. If water is reaching a light fitting or switch, keep clear of it. Then the source needs tracing. For older village homes like those around Essendon, the right replacement materials are not always easy to find quickly. Spotting a problem early leaves room to find them.
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. The price is confirmed before you book.

Your questions about roof leak investigations in Essendon
Will you come out to Essendon?
Yes, we do. We survey roofs across London and the South East, from towns to the smallest villages. The journey is planned ahead, so it helps to know about access.
Do you carry out roof surveys in Essendon?
Yes. We survey roofs across London and the South East, and Essendon is part of that. You can call 07833 053749 or email us with the address and a few details, and we will talk through which survey suits.
Can you tell me if my roof has asbestos?
No. We can flag materials that might contain asbestos, but only a specialist asbestos surveyor can confirm it. It may be present in buildings built or refurbished before 2000.
Is thermal imaging part of a leak investigation?
It can, when the conditions are right. It works best after a sunny day, with a dry roof surface and little wind. Wet insulation holds heat longer than dry, which can show up on the image. We always check what it shows with moisture readings.
What does the report include?
Written findings with photos, explaining the condition of the leaking roof, any defects and our recommendations. Standard adds moisture detection and a structural check; Premium adds thermal imaging, drone inspection where applicable and structural analysis.
Will I get photos?
Yes. Photographs are taken throughout the survey, and the report uses them to show each finding.
Will you definitely find the leak?
We can’t promise to find every leak on one 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.
The survey, step by step
Where it is relevant and can be reached safely, the roof space is checked as well as the outside. In the loft, the signs we look for are staining, damp, daylight and sagging, as far as the space allows. All in, the survey usually takes between one and two hours for a house, and longer for a large or complex roof. Somewhere like Essendon needs a little journey planning: let us know about lanes, gates and parking. The roof is looked at from ground level, from windows, from the loft where there’s safe access and from the roof where it is safe.
- You get in touch with details of the leak and any photos.
- We check the stain, the ceiling and the loft above it.
- We check the likely entry points outside, like flashings, valleys, chimneys and gutters.
- We use moisture detection, and thermal imaging where it is useful.
- We email a report with photographs, the likely entry point and recommendations.
Before we arrive
- For flats, check roof access has been agreed
- Make sure the loft hatch can be reached
- If you’re buying, check with the agent that we can get in
