About our roof leak investigation in St John's
On older houses, leaks often start at lead work and hidden gutters. Lead flashings crack or lift, valley linings wear and parapet gutters overflow when outlets block. If your home has a butterfly roof, the central valley gutter is a common culprit in heavy rain. Parapet walls and their gutters are looked at from wherever it’s safe. Our report shows what we found, with photos. We survey lead flashings, valleys and parapet gutters and chimney stacks, and common reasons people get in touch are leaks at a dormer or roof window and water dripping from rafters or underlay.
In a smaller place like St John's, some roofs face open ground, so wind and driving rain find any weakness in ridges, verges and flashings. If a leak shows only when the wind is in a certain direction, that’s a useful clue. Tell us when it happens when you contact us. Gutters and downpipes on the exposed side are worth a look as well.
Nothing in the report is left vague: if work is needed, the report says so clearly, and where it can wait, that’s said too.

Rented homes, blocks and businesses
Letting agents often book on a landlord’s behalf, and the report can go to both. We agree a time with the tenant beforehand.
We survey roofs for landlords and letting agents as well as householders. A written report with photos gives you a clear record of the leaking roof, useful for planning maintenance.
Roof leak investigations in St John's: local notes
Listing and conservation areas can both shape what roof work is allowed on an older home. The council is the place to check, along with Historic England’s list. In Surrey, older roofs are often handmade clay tile, with tile-hanging on many upper walls. A few of Surrey’s oldest buildings have heavy Horsham stone slab roofs. The covering and its details give the first clues when tracing where water is coming from.
If you run a business near The Peacocks, finding where water is getting in quickly keeps disruption down. Take an older house close to St John's Church: old mortar, worn lead and slipped slates are the usual suspects when water gets in.

Why act early in St John's
A leak that returns after a repair typically means the real source wasn’t found. We look past the obvious spot and check each likely route. That’s frequently what breaks the cycle. Tradespeople may need to travel further to a smaller place like St John's, so it’s useful to plan roof work rather than call someone out in a hurry. Knowing early gives you time to get the right people in.

Common roof problems in St John's
Flashings are one of the commonest sources of roof leaks. Where a roof meets a chimney, a wall or a dormer, lead or mortar seals the joint. When lead lifts or splits, or a mortar fillet cracks, rain runs straight in.
These are some of the problems a survey can pick up:
- Staining where a gutter or parapet meets the wall
- Damp ceilings under a flat roof
- A leak that comes and goes with the weather
- Damp patches next to the stack
If you look after a building such as The Winston Churchill School A Specialist Sports College, on a building that size, finding the source of a drip means looking well beyond the stain.
Before booking anyone

- Whether the roof space is looked at, where there is one
- What happens after the report arrives
- Their report turnaround times
What happens on the day
The visit has one job: to look at the leaking roof as closely as is safe and record what we find. Notes and photographs go into the written report. It usually takes about one to two hours at a typical home, though large, tall or awkward roofs take more time. Some parts of a survey depend on the weather, so a visit to St John's is booked with the forecast in mind: the parts that need calm, dry weather are planned around it.
- We start with your notes and photos of the leak.
- Inside, we check the stain and the ceiling around it.
- From the loft space, we trace the water’s route where there’s safe access.
- Outside, we check flashings, valleys, chimneys, gutters and flat roof details from every safe vantage point.
- You receive a report with the likely source, photos and recommendations.
Preparing for the visit
- For a flat or shared roof, check access with the freeholder or managing agent
- Keep pets in another room
- Have any questions written down, so nothing gets missed

Common questions in St John's
Will you come out to St John's?
Yes, we do. We cover the whole of London and South East England, and smaller places are part of that. Longer journeys are simply planned beforehand.
Do you cover St John's?
Yes, St John's is one of the places we work. The survey and report are the same in St John's as anywhere else, and visits run on weekdays and weekends.
How do you tell a leak from condensation?
Many apparent leaks turn out to be condensation. Leaks tend to follow wet weather and show in one place, while condensation is often widespread and worst on cold days. The report explains which it looks like and what to do.
Can you inspect my roof with a drone?
Yes, where it applies and safe. We’re a CAA-registered drone operator (Flyer ID and Operator ID), flying a sub-250g drone. It’s included in the Drone Roof Survey and, where it applies, the Premium Survey.
Is this an asbestos survey?
No. We don’t 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.
What should I do before you arrive?
Keep a note of when it leaks, and take photos. Move stored items away from the loft hatch. If water is near any fittings, have an electrician check them.
Do you climb onto every roof?
Only where it is safe to do so. We inspect everything that’s safely in view: from the ground, from windows, from inside the loft space, from the roof where it is safe and by drone where applicable. The report says if anything couldn’t be seen.
Prices for roof leak investigations in St John's
Several things affect the price of a survey:

Useful tips for St John's property owners
Most of what helps is simple and safe from ground level. Our suggestions:
- Do not climb onto the roof to look
- Keep a photo record of the damp patch
- Tell us about any past repairs to the roof
- Mention any plumbing above the damp area
Where we find more than one possible route, we say which is most likely and why. We say which items need prompt attention, so you know what to deal with first.
Look at the roof from the ground after strong winds. Pieces of slate or tile in the garden mean something has moved. Small faults dealt with quickly rarely become leaks.
