Roof leak investigations for homes and businesses in Sandridge
Water is good at hiding where it gets in. It can run along a rafter, a batten or the underlay before it drips, so the stain on your ceiling is seldom right under the hole. Our leak investigation traces it back, one likely route at a time. A repair aimed only at the stain can miss the cause entirely. Finding the route first lets the repair go where it’s needed. Common reasons to book are a leak that comes and goes with the weather and water coming in around a roof light or dormer, across flat roof details, valleys and parapet gutters and the roof space.
Somewhere as small as Sandridge, older roofs have often been repaired many times. A new leak may be fresh damage or the latest sign of long-term wear, and the difference matters, especially to an insurer. The report says what was seen and what it points to. Damp in old walls and timbers is slow to dry, so the sooner the cause is found the better.
Where we cannot see part of the leaking roof, the report says so. That way, it’s clear what was covered and what wasn’t.

What we look for on each type of roof
Valleys
Debris in a valley slows the water and pushes it sideways. In heavy rain, it can spill under the edges of the slates or tiles.
Chimney stacks
Our chimney check is a visual inspection of the stack, not a flue, gas or sweep inspection.
Surveys for landlords and agents in Sandridge
A roof problem in a let property affects your tenants as well as the building. A survey helps you spot issues early and plan the work.
We also survey roofs for businesses and commercial landlords, from shops and offices to industrial units. Bigger roofs take more time.
Signs you need a roof leak investigation in Sandridge
Flashings are one of the commonest sources of roof leaks. Lead or mortar closes the gap wherever a roof meets a wall, chimney or dormer. Once that seal cracks or lifts, water gets behind it, often well away from where it shows.
Things that often lead to a survey include:
- Water coming in around a roof light or dormer
- Brown rings on upstairs ceilings
- Wet patches on loft insulation
- Wet patches high on an inside wall
For businesses in and around places such as The Maltings, water through a ceiling can damage stock and close a sales floor, so the source needs finding fast.
Choosing a roof surveyor
- What follow-up you get after the report
- Will they check the loft as well as the outside?
- Whether VAT is added on top
- How long they’ve been surveying roofs
What a survey costs
A few things affect what a survey costs:
- The height of the building and how the roof can safely be seen
- How many separate roofs there are, such as extensions, dormers and garages
- The roof’s overall size
- The shape of the roof and its details
Our price is from £150, including VAT. Basic starts from £150, Standard from £250 and Premium from £400, VAT included, and we will tell you which fits.
What to let us know when you contact us
There is no need for technical words. It’s enough to let us know:
- The kind of building and roof involved
- Anything about access we should know
- Pictures of the roof from a safe spot, if you have them
- Your timetable, such as an exchange date
Once you know what you need, ring 07833 053749 or drop us an email. From there it’s a case of choosing a package, agreeing the price and fixing a day.
What happens on the day
When we arrive, we start by asking what you’ve noticed and what you want to find out. After that, we look at everything we can see safely. Most surveys take an hour or two at a typical home, with bigger or more complicated roofs taking longer. Older roofs in small places like Sandridge can have low, tight loft spaces, so let us know about the loft hatch and any ladder. We only go where it is safe.
- You pick a Basic, Standard or Premium Survey.
- A visit is booked for a weekday, Saturday or Sunday.
- The investigation works from the stain back to the roof.
- Moisture detection and thermal imaging are used where your package includes them and they help.
- You get photos, the likely cause and clear recommendations.
Before we arrive
- Jot down any questions you want answered
- If it isn’t your property yet, arrange access through the agent
- Find any records of previous roof work
Booking a survey

Sandridge questions
Do you cover smaller places like Sandridge?
Yes, Sandridge is on our map. A small place gets exactly the same survey as a big one.
Do you cover Sandridge?
Yes, Sandridge is within the area we cover. We work right across London and South East England. Just ring 07833 053749 or send us an email and let us know about the property.
Does the investigation include the repair?
The investigation is about finding the cause. The repair isn’t part of it. You get a report with photos showing where the water is getting in and what needs attention.
Is this an asbestos survey?
No. We do not sample or test for asbestos. Where a material might contain it, such as old cement sheets on a building from before 2000, the report flags it, with a recommendation to have a specialist asbestos surveyor check before it is disturbed.
Do you take photos of the roof?
Yes. Photos are taken throughout the survey, and they go into the written report.
Are you insured?
Professional indemnity and public liability insurance cover our surveys. If you need details for a managing agent or a building owner, just ask.
What do I do with the report?
The report arrives by email, with photos and clear recommendations. With Standard there is a follow-up consultation; with Premium, an in-person consultation.
Leaks and storm damage in Sandridge
Historic houses like Childwickbury Manor, about 2 miles west, show how far back building in the area around Sandridge goes. If your house is among 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. 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.
If you let a flat or house near St Albans station, tracing a leak quickly matters when a tenant is living with it. Take an older house close to St Leonard's Church: the leak may come from a chimney, a valley or tired lead rather than the covering itself.
