What a survey costs
Not every roof costs the same to survey, and it comes down to:
- Roof area
- Extensions, dormers and garages with roofs of their own
- House, block, shop or office
- Height and safe access
Simple, low roofs take less time to survey than tall or complicated ones, and the package matters as well. We will give you the figure before anything is booked.

Roof leak investigations for homes and businesses in Longcross
The aim is to find where the water is getting in and explain it. 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. The investigation finds and explains the cause, and the repair itself is a separate job. We survey valleys and parapet gutters, chimney stacks and slate and tile slopes, and people most often book us about staining around the chimney inside and brown rings on upstairs ceilings.
Somewhere as small as Longcross, older roofs have often been repaired many times. That makes it hard to tell new damage from old wear, which matters if you are thinking of an insurance claim. 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.
You receive the findings by email, easy to pass on to a roofer, an agent or an insurer. Turnaround is within 48 hours for Basic, 24–48 hours for Standard and same day for Premium.

Leaks and storm damage in Longcross
Many older homes in Surrey have handmade clay tiles and tile-hung upper walls. 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. Botleys Mansion, about 2.3 miles east, is one of the historic houses in the wider area around Longcross. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and any change of roofing material on a listed home needs checking with the council first.
If you own a rental within reach of Longcross station, a tenant living with a leak needs the cause found, not just the stain painted over. Living close to Gracious Pond is pleasant, but mature trees mean leaves in gutters and valleys each autumn. The streets around a church like Longcross Church are often among the oldest in a place, and if your house is among the older ones nearby, old mortar, worn lead and slipped slates are the usual suspects when water gets in.
Longcross is about 4 miles south-west of Egham, in Surrey. Longcross is part of the area we cover and the surrounding area as part of our work across London and the South East. Longcross is one of the towns and villages in Surrey we cover for roof leak investigations. There is also a page for Guildford.

Tips from our surveys
Nothing here needs a ladder. A few suggestions:
- Keep water away from lights and sockets
- Tell us if there are tanks or pipes in the loft
- Take dated photos of the leak
- Protect furniture and flooring under the leak
Any roofer you ask to quote can work from the report. They’ll see exactly where the problem is, so the repair is aimed at the cause.
Have leaves and moss cleared from gutters, valleys and outlets, especially in autumn. Blocked outlets on parapet and flat roofs cause many leaks. Use a professional rather than climbing up yourself.
Checking the roof from ground level
Fresh stains on ceilings or walls after rain are worth noting. Photograph them and note the date, as it helps a surveyor trace the cause.
You can learn a lot from the ground. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Never climb onto the roof to look.
Leave it or get it looked at?
Patching the spot above the stain often does not work. The real way in may be a metre or more away. We find the probable source before anyone starts work. Older cottages and farmhouses around Longcross can have roof timbers that have been there a very long time, where water from a failed roof can cause rot if it is left.
There are three survey packages: Basic from £150, Standard from £250 and Premium from £400, with VAT included. The price for your roof depends on its size, access and what you need to know.

Different roofs, different checks
Chimney stacks
Damp on a chimney breast inside frequently starts at the top of the stack. Open, unused pots let rain fall down the flue.
Valleys
A valley takes the rain from both sides of the roof. Worn or split linings and slipped valley tiles let it under the coverings.
The survey, step by step
Photos are taken throughout the visit, so the report shows exactly what we saw. We take close-ups from wherever is safe, including by drone where it is applicable and the weather allows. A typical visit takes about one to two hours, more where the leak is intermittent or the roof is large. Around Longcross, older homes can have small or awkward roof spaces, so let us know about the loft hatch and any ladder. Only areas that can be reached safely are inspected.
- You pick a Basic, Standard or Premium Survey.
- We agree a date, including weekends.
- We inspect inside and out, starting from the stain.
- Where it is useful and included, we take moisture readings and use thermal imaging.
- You get photos, the likely cause and clear recommendations.
Getting ready for the survey
- Show us where any leaks or stains appear
- Tell us about parking before the day
- Have any questions written down, so nothing gets missed

Longcross questions
Is my home in Longcross listed or in a conservation area?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you are planning to re-roof in a different material.
Do you cover smaller places like Longcross?
We do. Villages and rural addresses get the same survey as a town house.
Do you climb onto every roof?
Not always. Some roofs are too steep or fragile to walk on safely. Safe viewpoints, the loft and a drone where it applies let us see the rest.
Is this an asbestos survey?
No. Asbestos surveys and testing are not part of what we do. We flag materials that could contain asbestos, such as cement sheets or soffits on pre-2000 buildings, and recommend a specialist asbestos surveyor checks them before they’re disturbed.
Do you need to get into the loft?
If the survey needs it and the loft space can be reached safely, yes. A clear path to the hatch helps, and if the loft cannot be reached safely, the report says so.
Why is the stain in a different place from the leak?
Water follows the easiest path, not the shortest. On a flat roof it can travel under the covering before it finds a way through the ceiling. Tracing that path is the heart of a leak investigation.
Is it a leak or condensation?
Many apparent leaks turn out to be condensation. A leak typically shows in one area and follows rain, while condensation is often widespread and worst on cold days. We tell you which it is most likely to be.
