How a roof leak investigation works in Chandler's Cross
Some leaks only appear in certain weather. Wind-driven rain, an overflowing gutter or snow melt may be what triggers it. Notes on when it leaks, and what the weather was doing, help us, along with any photos you’ve taken. We look for the clues it leaves behind, like tide marks, stained timbers and damp underlay. Moisture detection shows which materials are still damp. Common reasons to book are water dripping from rafters or underlay and drips from nail tips in a cold loft, on valleys and parapet gutters, lead flashings and slate and tile slopes.
Somewhere as small as Chandler's Cross, older roofs have frequently been repaired many times. That makes it hard to tell new damage from old wear, and the difference matters, particularly 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.
After the visit, you get a written report with photos, emailed to you. It explains the condition of the leaking roof, the defects we found and what we recommend.

What we do, step by step
You don’t need to do much on the day. Point out anything you’ve noticed, like stains, drips or loose pieces, and we will get on with the inspection. The survey itself takes roughly 1–2 hours, more where the leak is intermittent or the roof is large. Cottages and farmhouses around Chandler's Cross frequently have roofs at several levels, with lean-tos and outbuildings attached. We work round each section in turn, from the safest viewpoints, and anything we cannot see is noted.
- You get in touch with details of the leak and any photos.
- The visit starts indoors, at the stain and in the loft.
- Likely entry points outside are looked at, from flashings and valleys to gutters and outlets.
- Where it helps, we take moisture readings and use thermal imaging.
- Your report sets out where the water is most likely getting in, with photos and recommendations.
Before the survey

Some things can’t be seen without opening up the roof, and that sets some limits:
- The repair itself (the investigation finds and reports the cause)
- An intermittent leak that shows no trace on the day

Roof by roof
Flat roof upstands and outlets
On a flat roof, a leak can show some distance from the split. Where conditions allow, moisture readings and thermal imaging help narrow it down.
Slate and tile slopes
Cracked mortar lets ridge and hip tiles move. Rain can then run in at the ridge.
Leaks and storm damage in Chandler's Cross
Older houses in the South East frequently have slate or clay tile roofs, while many later estates have concrete tiles, and flat-roofed additions turn up almost everywhere. Where water gets in depends a good deal on what the roof is made of and how it’s detailed. The wider area around Chandler's Cross has a long history of building, with Chenies Manor House about 3.2 miles west. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and the council can say whether a home is in a conservation area.

Chandler's Cross: your questions answered
Does a conservation area affect roof work in Chandler's Cross?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it is in a conservation area. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Will you come out to Chandler's Cross?
Yes, we do. Our area covers London and South East England, and smaller places are part of that. Longer journeys are simply planned ahead of time.
Will I get photos?
Yes, plenty. Pictures sit next to the findings they show.
Are you insured?
Our cover is professional indemnity plus public liability, and we can provide details if a managing agent needs them.
Do you look in the roof space?
If the survey needs it and the loft space can be reached safely, yes. Please clear anything stored under the hatch, and if the loft can’t be reached safely, the report says so.
Do you survey roofs on blocks of flats?
Yes, once access has been agreed. The roof of a block or converted house is often shared, so we need permission from whoever owns or manages the building. We can only inspect what we’re given access to.
