Crondall Roof Leak Investigation
We carry out roof leak investigations in Crondall and the rest of Surrey. Surveys run seven days a week.
- Damp ceilings under a flat roof
- Damp on a chimney breast
- Wet patches on loft insulation
What you can safely check yourself
A lot can be seen from the ground. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Please don’t climb up for a closer look.
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it.
Roof leak investigations for homes and businesses in Crondall
Flat roofs leak in their own ways. Common causes are splits and blisters, tired upstands and outlets that do not drain. Standing water puts extra pressure on every weak point. We check both the covering and the room underneath to narrow it down. Flat roofs over extensions, garages and dormers are frequent sources of leaks. Felt often lasts around 15 to 20 years, so age is part of the picture. We survey chimney stacks, slate and tile slopes and flat roof details, and people most often book us about drips in the loft during heavy rain and leaks below a flat extension roof.
Somewhere as small as Crondall, older roofs have frequently 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. Older walls and timbers hold water for a long time, so it’s worth finding the cause soon.
The report is yours to share with whoever needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent.

Your questions about roof leak investigations in Crondall
Does a conservation area affect roof work in Crondall?
Your council is the best source, with Historic England’s list for listed buildings. A change of roofing material may need consent in either case, and councils can also use Article 4 directions.
Do you cover smaller places like Crondall?
We do. A small place gets exactly the same survey as a big one.
Why is the stain in a different place from the leak?
Rain that gets in will run along whatever it lands on. On a flat roof it can travel under the covering before it shows. Tracing that path is the heart of a leak investigation.
What happens next?
The report arrives by email, with photographs and clear recommendations. The Standard Survey includes a follow-up consultation, and the Premium Survey an in-person consultation.
Can you find a leak when it isn’t raining?
Normally, yes. Moisture detection shows where materials are damp even on a dry day. For leaks that only happen in certain storms, we report the most likely routes.
Does the investigation include the repair?
This service finds and reports the cause, and the repair is separate. The report gives any roofer a clear brief.
How much does a roof leak investigation cost in Crondall?
Our price is from £150, including VAT. Our three packages are Basic from £150, Standard from £250 and Premium from £400, with VAT included.
When you need someone else
No survey can tell you everything, and it’s better to know them up front. Bear these in mind:
- Defects hidden under coverings or inside walls without opening up
- Leaks from plumbing, tanks or pipework rather than the roof
- A promise to find every leak on a single visit

Roof leak investigations around Crondall
Handmade clay tiles and tile-hung walls are typical of Surrey’s older houses. Some old buildings in Surrey and Sussex have Horsham stone slab roofs. Knowing the roof type helps narrow down where water may be getting in. The wider area around Crondall has a long history of building, with Farnham Castle about 2.7 miles east. Older homes in the wider area frequently have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years, and any change of roofing material on a listed home needs checking with the council first.
Landlords with a home close to Farnham station may find that a tenant living with a leak needs the cause found, not just the stain painted over. For businesses in and around places such as Hart Shopping Centre, a quick answer on where water is coming in keeps a business running.
Crondall is about 3 miles south of Fleet, in Surrey. Surveys in Crondall work the same way as everywhere we cover: a careful inspection, photographs and a written report. We cover towns and villages across Surrey. You can also see our page for Guildford.
All of GU10 is covered for roof leak investigations. If you need a roof leak investigation at a property on Church Street, The Borough and Glebe Road or a nearby road, we can help. We also cover the places around Crondall: Redlands (1 mile north-east), Bowling Alley (1 mile north), Dora's Green (1 mile east), Warren Corner (1 mile east) and Mill Lane (1 mile north).

Local landmarks in Crondall
Typical jobs here are in homes near The Plume Of Feathers Public House and St Nicholas' School and the streets around them.

For landlords and managing agents
Roof problems in a rented home affect tenants as well as the building. A survey helps you spot issues early and plan the work around your tenants.
Letting agents can arrange access with tenants, at a time agreed ahead of time. We survey on weekdays and at weekends, which helps when tenants work during the week.

Signs you need a roof leak investigation in Crondall
Condensation is often mistaken for a leak. Moist air from bathrooms and kitchens condenses on the cold underside of the roof, particularly in lofts with blocked eaves. Drips from nails and damp underlay are typical signs.
A survey makes sense if you’ve noticed:
- A leak that comes and goes with the weather
- Damp underlay across a wide area
- Wet patches high on an inside wall
- Staining around the chimney inside
For site and facilities teams at buildings such as Crondall Primary School, tracing a leak on a big roof starts with where the water appears and works back.

What happens on the day
Safety comes first on every visit. Everything that can safely be seen is inspected, and anything we cannot see is noted in the report. The survey typically takes about 1–2 hours, more where the leak is intermittent or the roof is large. In a hamlet or village like Crondall, a postcode does not always lead to the right gate, so a few directions are welcome. After that, the survey runs as it would anywhere.
- You let us know where the water shows and when it appears.
- We look at the stain, the ceiling and the loft above it.
- We check the likely entry points outside, such as flashings, valleys, chimneys and gutters.
- Moisture readings and thermal imaging are used where they help.
- You receive a written report with photos showing the likely source and what needs attention.
Preparing for the visit
- Move anything stored under the loft hatch
- Gather any invoices or paperwork from past roof work
- Buyers: confirm access with the estate agent or seller

Advice
Practical tips
These tips come from what we see on roofs every week:
- Record whether it leaks in every downpour or only some
- Mention any plumbing above the damp area
- Tell us about any past repairs to the roof
- Keep water away from lights and sockets
If the leak turns out to be condensation, the report says so, with recommendations on ventilation. It saves chasing a leak that isn’t there.
Plan a roof survey every few years. They’re where most leaks start, and catching wear early keeps water out.
