Booking your survey
These details help when you contact us:
- How the loft is reached, if there is one
- What’s prompted the survey
- The property’s address and postcode
- Any stains, drips or damp patches you’ve seen indoors

How a roof leak investigation works in Redbourn
Moisture readings and thermal imaging are used where they’re useful. Moisture readings show which materials are wet. A thermal camera shows patterns of temperature rather than water, so its findings are checked with moisture readings. Moisture detection is included in the Standard Survey, and thermal imaging in Premium. Thermal imaging works best after a sunny day, on a dry roof with little wind. If you’ve noticed wet patches on loft insulation and staining where a gutter or parapet meets the wall, we can find out what’s behind it.
In a smaller place like Redbourn, some roofs face open ground, so wind and driving rain find any weakness in ridges, verges and flashings. If a leak shows only when the wind is in a certain direction, that’s a useful clue. Tell us when it happens when you contact us. Gutters and downpipes on the exposed side are worth a look as well.
If any part of the leaking roof couldn’t be seen safely, we say so in the report. That way, it is clear what was covered and what wasn’t.

FAQs for Redbourn
How do I find out if my home in Redbourn is listed?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it’s in a conservation area. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Is Redbourn within the area you cover?
We do. A small place gets exactly the same survey as a big one.
Is thermal imaging part of a leak investigation?
Where conditions suit, it can. It works best after a sunny day, with a dry roof surface and little wind. Damp areas can hold heat differently from dry ones. We always check what it shows with moisture readings.
Do you test for asbestos?
No. Our report may flag materials that could contain asbestos, but confirming it is a job for a specialist asbestos surveyor. It may be present in buildings built or refurbished before 2000.
How many surveys have you done?
We have more than 20 years’ experience and have completed over 5,000 surveys.
How should I prepare for the leak investigation?
Note when the leak appears and what the weather was doing, and take photos. Move stored items away from the loft hatch. Keep away from any light or socket that water is reaching.
Could my leak actually be condensation?
It is a common question. A leak normally shows in one area and follows rain, while condensation is often spread out and worse in cold weather. We tell you which it is most likely to be.
What we do, step by step
The aim of the visit is simple: to look at the leaking roof as closely as is safe and record what we find. Everything we note and photograph goes into the written report. The visit usually takes between one and two hours for most houses, and about three to four hours for a commercial roof. A visit to a smaller place like Redbourn is no different on the day: outside, inside and from any safe vantage point, in that order. It’s useful to show us anything you’ve already noticed.
- We start with what you’ve seen: where the stain is and when it gets worse.
- The visit starts indoors, at the stain and in the loft.
- Likely entry points outside are looked at, from flashings and valleys to gutters and outlets.
- We use moisture detection, and thermal imaging where it is useful.
- We email a report with photographs, the likely entry point and recommendations.
How to prepare
- Make sure we can get to the back of the property
- Have any questions written down, so nothing gets missed
- If the roof is shared, arrange access with whoever manages the building
Booking a survey
Prices start from £150, including VAT. What you pay depends on the roof’s size, access and the package, so ring 07833 053749 or email us with the details.
Related advice
Checking the roof from the ground
Look up at the roof after a storm, from the ground: 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.
Inside, the loft is a good place to look, with care. Take a torch and only step on boards or joists, checking for stains, damp wood or chinks of daylight.
Honest limits
In fairness, a roof survey has limits:
- Defects hidden under coverings or inside walls without opening up
- Leaks from plumbing, tanks or pipework rather than the roof
- A structural engineer’s report
If in doubt, call 07833 053749 or email us and we will suggest the right survey. What a survey covers and doesn’t.

Roof leak investigations in Redbourn: local notes
Historic houses such as Childwickbury Manor, about 2.6 miles south-east, show how far back building in the area around Redbourn goes. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and the council can say whether a home is in a conservation area. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles, with flat-roofed extensions, dormers and garages common everywhere. The covering and its details give the first clues when tracing where water is coming from.
Trees in and around Rothamsted Park shed leaves that can end up in nearby gutters, and an overflowing gutter soon means a wet wall. Landlords with a home close to Harpenden station may find that a tenant living with a leak needs the cause found, not just the stain painted over.
Redbourn is about 2 miles south-west of Harpenden, in Hertfordshire. Surveys in Redbourn work the same way as everywhere we cover: a careful inspection, photos and a written report. Across Hertfordshire, we cover Redbourn and the places around it. Milton Keynes is in our area too.

Leave it or get it looked at?
Leaks tend to get worse, not better. Wind lifts loose slates further and gaps widen. An investigation now gives you time to plan the work. In a smaller place like Redbourn, wherever a roof is exposed, a loose ridge or flashing does not stay loose for long. Each storm lifts it a little further, and water follows.
We offer three survey packages: the Basic Survey from £150, the Standard Survey from £250 and the Premium Survey from £400, all including VAT. What your roof costs depends on its size, access and what you want to find out.

Signs you need a roof leak investigation in Redbourn
Blocked gutters can look like a roof leak. Hidden gutters behind parapets cause the most trouble, because when they block, water backs up and runs inside.
A survey can pick up problems like:
- Water coming in around a roof light or dormer
- Wet patches on loft insulation
- Staining where a gutter or parapet meets the wall
- Damp ceilings under a flat roof
If you look after a building such as Redbourn Primary School, water through a big roof can travel a long way before it drips, so the search covers more than the obvious spot.
