How a roof leak investigation works in Horsell
We use moisture detection and thermal imaging where they help. Moisture detection confirms where timbers, plaster or insulation are damp. A thermal camera shows patterns of temperature rather than water, so we confirm what it suggests 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. We survey rooflights and dormers, lead flashings and slate and tile slopes, and the problems we’re asked to look at most are leaks that appear only in driving rain and wet patches on loft insulation.
In a smaller place like Horsell, some roofs face open ground, where driving rain gets into any gap at a ridge, verge or flashing. A leak that only appears in certain weather frequently points to an exposed detail. It helps to know when and where the water appears. The gutters on the most exposed side can overflow too.
After the visit, you get a written report with photographs, sent by email. It explains the condition of the leaking roof, the defects we found and what we recommend.

Practical tips
Nothing here needs a ladder. A few suggestions:
- Have an electrician check any wet fittings
- Clear the loft hatch so we can get in
- Put a bucket under the drip and move valuables
- Let us know if there are tanks or pipes in the loft
Your report arrives by email. It explains the likely entry point, the route the water takes and our recommendations. Basic reports come within 48 hours, Standard within 24 to 48 hours and Premium the same day.
After a storm, check the roof from the garden and the street. Pieces of slate or tile in the garden mean something has moved. Prompt repairs stop gaps turning into leaks.
FAQs for Horsell
Is Horsell within the area you cover?

No. We do not carry out asbestos surveys or testing. We flag materials that could contain asbestos, such as cement sheets or soffits on pre-2000 buildings and suggest a specialist asbestos surveyor checks them before any work.
How should I prepare for the leak investigation?
Note when the leak appears and what the weather was doing. Clear access to the loft. If water is near any fittings, have an electrician check them.
Do you survey roofs on blocks of flats?
Yes, once whoever controls the roof agrees access. We look at the parts we are given access to.
What’s in the report?
It works through the roof part by part, in writing and with photos, and ends with what we recommend. The most urgent items are made clear.
How much does a roof leak investigation cost in Horsell?

Horsell roofs and the weather
Older houses across Surrey frequently have handmade clay tiles, and many have tile-hanging. Some old buildings in Surrey and Sussex have Horsham stone slab roofs. Where water gets in depends a good deal on what the roof is made of and how it’s detailed. The wider area around Horsell has a long history of building, with Botleys Mansion about 3.3 miles north. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and any change of roofing material on a listed home needs checking with the council first.
Anyone responsible for a site like Woking High School will know that on a building that size, finding the source of a drip means looking well beyond the stain. Living close to Milford Green and Coxhill Green is pleasant, but mature trees mean leaves in gutters and valleys each autumn, and an overflowing gutter soon means a wet wall.
Horsell is about 1 mile north-east of Woking, in Surrey. Roofs in Horsell get the same thorough look as anywhere else in Surrey. Horsell is one of the towns and villages in Surrey where we work. We also survey roofs in Guildford.

What you can safely check yourself
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry and it will help the survey.
You can learn a lot from the ground. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Please do not climb up for a closer look.
How it works
The visit normally starts outside and finishes in the loft: outside views come first, then the loft space if there’s safe access. In total, it takes between one and two hours at most homes, rising to roughly 3–4 hours on a commercial building. For a survey in Horsell, we agree the time, the access and parking before the day. Weekday and weekend visits are both possible. If there are outbuildings or garages you want looked at, mention them.
- You let us know where the water shows and when it appears.
- The visit starts indoors, at the stain and in the loft.
- Likely entry points outside are checked, from flashings and valleys to gutters and outlets.
- Where it helps, we take moisture readings and use thermal imaging.
- You receive a written report with photos showing the likely source and what needs attention.
Before the survey
- Clear the way to the loft hatch
- Tell us about parking before the day
- Keep pets inside or away from the areas we are looking at

Why get it checked now?
Guesswork repairs are a common reason leaks keep coming back. Because water travels, the real entry point may be somewhere else. An investigation finds the likely cause first. On a bungalow or cottage around Horsell, the roof sits close to the rooms below, so a small leak can mark a ceiling within a few storms. Catching the cause first saves redecorating as well.

What we are asked to look at in Horsell
A roof valley collects the rain from two slopes. Split linings, slipped valley tiles or debris can send that water under the coverings. Leaks from valleys often show up some distance away inside.
Look out for signs like these:
- Damp patches next to the stack
- Damp walls below an overflowing gutter
- Water that shows only in certain storms
- Water through the ceiling under a flat roof
The streets around a church such as Church of St Mary the Virgin are often among the oldest in a place, and if yours is one of the older homes nearby, lead flashings, valleys and old chimneys are typical places for water to get in.
