Roof leak investigation in Sevenoaks: what you get
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 and so do photos. Even on a dry day, a leak usually leaves clues: stained timbers, tide marks and damp underlay. Moisture detection shows which materials are still damp. Typical surveys look at drips in the loft during heavy rain and damp underlay across a wide area, across rooflights and dormers, lead flashings and chimney stacks.
Many homes around Sevenoaks have been extended, often with flat roofs or dormers, and the joint between new and old is a classic place for water to get in. The flashings and upstands at those joints get a close look. Water can run along the top of a wall or a joist before it shows, so the stain is not always the place to look.
With the Standard Survey, you also get moisture detection, a structural check and a follow-up consultation. The Premium Survey goes further, with thermal imaging, drone inspection where it applies, structural analysis and an in-person consultation.

Leaks and storm damage in Sevenoaks
Handmade clay tiles, including Kent peg tiles hung on pegs through two holes, are typical of older Kent buildings. Oast houses and timber-framed Wealden hall houses are part of the county’s older buildings too. Each of these roof types has its own typical places for water to get in. With Knole House about 1.3 miles south-east, Sevenoaks sits in an area with a long building history. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and a listed home or one in a conservation area may need consent for changes of material.
If you live in an older home near St John the Baptist, the leak may come from a chimney, a valley or tired lead rather than the covering itself. If you own a rental within reach of Sevenoaks station, a clear finding on where water gets in helps you brief a roofer straight away.

Different roofs, different checks
Parapet and box gutters
Parapet and box gutters sit behind walls or inside the roof. A blocked outlet sends water over the lining and into the building.
Lead flashings
Wherever a roof meets a wall or stack, a flashing keeps rain out. We check for lead that has lifted, split or slipped, and for flashings that have been patched with bitumen.
Common questions in Sevenoaks
Does a conservation area affect roof work in Sevenoaks?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it’s in a conservation area. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Do you cover Sevenoaks?
Yes. We cover the whole of London and South East England, and Sevenoaks is part of that. Just call 07833 053749 or use the contact form and tell us about the property.
How long have you been surveying roofs?
More than 5,000 surveys over 20+ years.
Can you trace a leak in dry weather?
Typically, yes. Moisture detection shows where materials are damp even on a dry day. If a leak only appears in driving rain from one direction, we’ll tell you what we found and what’s most likely.
When does the report arrive?
Report times are set by the package. Basic: within 48 hours. Standard: 24 to 48 hours. Premium: the same day. If you have a deadline, such as an exchange date, tell us when booking.
Does the investigation include the repair?
The investigation is about finding the cause. The repair itself is a separate job. The report shows where the water gets in and what should be done, which whoever carries out the work can follow.
Do you carry professional indemnity insurance?
Our surveys are covered by professional indemnity and public liability insurance. Ask if you need details for a managing agent or building owner.
Useful tips for Sevenoaks property owners
From years of surveys, a few habits stand out as worth the effort:
- Move stored items away from the hatch
- Put a bucket under the drip and move valuables
- Tell us if there are tanks or pipes in the loft
- Let us know about any past repairs to the roof
Keep the report after the work is done. If the leak returns, it’s a useful record of what was found.
Keep gutters, valleys and outlets clear, ideally once the leaves have fallen. Blocked outlets on parapet and flat roofs cause many leaks. Leave the clearing to someone with the right equipment.
What we do, step by step
After the inspection, everything we found is written up as a report with photographs. As for time on site, most surveys take roughly 1–2 hours for most houses, with bigger or more complicated roofs taking longer. In Sevenoaks, parking is rarely complicated, though it is useful to know about driveways or restrictions. The inspection covers what can safely be seen from outside, from windows and from the loft space.
- You let us know where the water appears, when, and what the weather was doing.
- We examine the damp area and the rooms near it.
- From the loft space, we trace the water’s route where there is safe access.
- Outside, we check flashings, valleys, chimneys, gutters and flat roof details from every safe viewpoint.
- You receive a report with the likely source, photos and recommendations.
Before the survey
- Buyers: confirm access with the estate agent or seller
- Mention any parking restrictions on your street
- Let us know about any leaks, stains or damp patches you know of
How to book
Prices start from £150, including VAT. What you pay depends on the roof’s size, access and the package, and you can ring 07833 053749 or send us an email to find out.

DIY checks: what’s safe
After heavy rain, check ceilings and the tops of walls for new stains. Photograph them and note the date, as it helps a surveyor trace the cause.
The one thing to avoid is getting up close. Slates, tiles, flat roofs and rooflights can give way. That’s where a survey comes in, using safe viewpoints and a drone where it applies.
Common roof problems in Sevenoaks
A gutter that overflows can soak a wall and mark the ceiling inside. Parapet and box gutters are the worst for this, since a blocked outlet sends water over the lining and into the building.
Things that often lead to a survey include:
- Drips from nail tips in a cold loft
- Leaks below a flat extension roof
- Damp patches next to the stack
- Drips in the loft during heavy rain
If you look after a building such as Sevenoaks Primary School, water through a big roof can travel a long way before it drips, so the search covers more than the obvious spot.
Questions to ask before booking
- Their drone registration, if they fly one
- When you will get the report
- Will they check the loft as well as the outside?
- Their insurance cover
