Do you need a roof leak investigation in Radwell?
Flat roofs fail with age and wear. Felt frequently lasts around 15 to 20 years, and splits, blisters and lifting laps let water in. Upstands and outlets are common weak points.
People usually book a survey when they’ve noticed one of these:
- Water marks that spread in wet weather
- Leaks that appear only in driving rain
- Drips from nail tips in a cold loft
- Water coming in around a roof light or dormer
If you let a flat or house near Baldock station, a tenant living with a leak needs the cause found, not just the stain painted over.
What to check before booking
- What exactly goes into their report
- Do they have a CAA Flyer ID and Operator ID for drone work?
- Which viewpoints they use to see the roof
- Their track record with similar roofs
Roof leak investigation in Radwell
Our job is to find the likely source and tell you. You get a written report with photos showing the likely entry point and the route the water is taking, plus recommendations on what needs attention. It gives any roofer a clear brief. We find and report the source, and the repair itself is a separate job. We survey flat roof details, lead flashings and chimney stacks, and the problems we’re asked to look at most are leaks at a dormer or roof window and wet patches on loft insulation.
In a village or hamlet like Radwell, older cottages and farmhouses frequently have roofs that have been patched over many years. That makes it hard to tell new damage from old wear, and the difference matters, especially to an insurer. We look at what can safely be seen and set out what we find. Older walls and timbers hold water for a long time, so it’s worth finding the cause soon.
The written findings come by email, ready to forward to whoever needs them. Turnaround is within 48 hours for Basic, 24–48 hours for Standard and same day for Premium.

Your questions about roof leak investigations in Radwell
How do I find out if my home in Radwell is listed?
For listing, use Historic England’s list; for conservation areas, ask the council. The answer matters most when a change of material is on the cards.
Do you carry out roof surveys in Radwell?
We do. Every survey there gets the same written report with photos.
Do I have to be there for the survey?
It depends on what we need to see. For inside areas and the roof space, someone has to give us access, while outside access can be discussed as you book.
How much is a survey?
Prices start from £150, including VAT. The final figure depends on the roof and the package you choose, and it’s agreed before booking.
What should I do before you arrive?
Keep a note of when it leaks, and take photos. Clear access to the loft. If water is near any fittings, have an electrician check them.
Can a leak be traced on a dry day?
In most cases, yes. Damp materials can be found without rain. For leaks that only happen in certain storms, we report the most likely routes.
How experienced are you?
Over 20 years and more than 5,000 surveys, across London and South East England.
How the survey changes by roof type
Parapet and box gutters
Parapet and box gutters sit behind walls or inside the roof. When their outlets block, water rises over the lining and runs indoors.
Lead flashings
Water from a failed flashing can travel down the wall or along a rafter. That’s why we check the flashings near a stain, not just the one directly above.
The survey, step by step
Photos are taken throughout the visit, so you can see in the report what we found and where. We take close-ups from wherever is safe. A typical visit takes between one and two hours for most homes, though a hard-to-trace leak can take longer. Somewhere like Radwell needs a little journey planning: let us know about lanes, gates and parking. The roof is looked at from the ground, from windows, from the loft where there is safe access and from the roof where it is safe.
- We help you choose the package that suits the leak.
- We agree a date, including weekends.
- The investigation works from the stain back to the roof.
- Where it is useful and included, we take moisture readings and use thermal imaging.
- You get photos, the likely cause and clear recommendations.
Before the survey
- If the roof is shared, arrange access with whoever manages the building
- Keep pets out of the way during the survey
- Let us know about parking near the property

Surveys for landlords and agents in Radwell
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 you book and we’ll plan the survey around it.
An agent can book and manage the survey for a landlord, and the report can go to both. We agree a time with the tenant beforehand.
Radwell roofs and the weather
The wider area around Radwell has a long history of building, with Hinxworth Place about 2.4 miles north. If your home is one of the older ones, expect a mix of original materials and later repairs on the roof, and any change of roofing material on a listed home needs checking with the council first. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates, and flat-roofed additions turn up almost everywhere. Different coverings let water in at different points, which shapes where the search starts.
If you look after a building like Norton St Nicholas CofE (VA) Primary School, a leak through a large roof is often found some distance from where the water shows inside. For an older house near a landmark such as Church of All Saints, leaks on older roofs frequently start at lead flashings, valleys or around old chimney stacks.

Why act early in Radwell
Lingering damp encourages mould on ceilings and walls. Once mould takes hold, it’s harder to clear. Finding the leak comes first. For an older or listed building in a place like Radwell, repairs may need matching materials and consent, so leaving a defect until it’s urgent leaves less time to plan.
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how it can be reached and seen safely. Prices start from £150, including VAT.
