Kemprow Roof Leak Investigation
Tracing where water is getting into your roof in Kemprow, carried out by an experienced roof surveyor. You get a clear written report with photos.
- Damp patches next to the stack
- Damp underlay across a wide area
- Damp walls below an overflowing gutter
What we look for on each type of roof
Slate and tile slopes
Cracked mortar lets ridge and hip tiles move. Rain can then run in at the ridge.
Flat roof upstands and outlets
Flat roof water can travel under the covering before it shows. Moisture readings and thermal imaging can help narrow it down where conditions suit.
Roof leak investigation in Kemprow: what you get
Our job is to find the likely source and tell you. The report shows, with photos, where we believe the water gets in and how it travels, 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. If you’re worried about leaks at a dormer or roof window and brown rings on upstairs ceilings, a survey will tell you what’s going on, on lead flashings, flat roof details and chimney stacks alike.
Being in a small place like Kemprow makes no difference to how a leak or storm damage is looked at: we simply plan the journey and access ahead. Let us know where the water shows, when it appears and anything you’ve noticed outside, along with any repairs done before. Photos of the stain and of the roof from outside are helpful too.
The report is yours to share with whoever needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent.

What happens on the day
Every visit follows the same pattern: we listen to what’s been worrying you, look at the roof from every safe viewpoint, take photos as we go and record our findings for the written report. It typically takes roughly 1–2 hours for a house; commercial roofs usually need 3–4 hours. Somewhere as small as Kemprow, access is frequently the only tricky part. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Visits can be on weekdays, Saturdays or Sundays.
- 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.
- The report explains the likely entry point and what needs attention.
Getting ready for the survey

Kemprow: your questions answered
Is my home in Kemprow listed or in a conservation area?
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. 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 Kemprow?
Yes. Kemprow is within the area we cover, which takes in towns, villages and rural addresses. We cover the whole of London and South East England. Let us know about access, parking and anything unusual about getting there when booking.
Can every leak be traced?
Not always, and we will be honest about that. Water can travel a long way, and some leaks only show in particular storms. If we can’t be sure, the report ranks the possible sources.
Will I get photos?
Yes. Photos are part of every report, so you can see exactly what each finding refers to.
How much is a survey?
Prices start from £150, including VAT. What you pay for your roof depends on its size, height, access and the package.
Is the repair included in the leak investigation?
The investigation is about finding the cause. The repair is not part of it. You get a report with photos showing where the water is getting in and what needs attention.
Do you use thermal imaging to find leaks?
Thermal imaging is used where it’s useful, and it’s included in our Premium Survey. It shows temperature differences, not water itself, so we confirm its findings with moisture readings.
Rented homes, blocks and businesses
Buyers’ agents can book surveys on behalf of their clients. Reports are emailed, so they’re easy to pass on, photos included.
Managing agents and residents’ management companies use roof surveys to plan maintenance. Recommendations are set out with the most urgent first where relevant, which helps with budgets and planning.
Roof leak investigations around Kemprow
Historic houses such as High Elms Manor, about 2.7 miles north-west, show how far back building in the area around Kemprow goes. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and the council can say whether a home is in a conservation area. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates, with flat-roofed extensions, dormers and garages common everywhere. Each of these roof types has its own typical places for water to get in.
Anyone responsible for a site like Fair Field Junior School will know that on a building that size, finding the source of a drip means looking well beyond the stain. For an older house near a landmark such as St John, old mortar, worn lead and slipped slates are the usual suspects when water gets in.

Can I check my roof myself?
After strong wind, take a look from the pavement or garden: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Leave anything above ground level to a survey.
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.

What else we do in Kemprow
Common roof problems in Kemprow
Valleys carry a lot of water. Worn lead, cracked linings or a build-up of leaves and moss can push water under the slates or tiles. The stain may appear well away from the valley itself.
A survey makes sense if you’ve noticed:
- Stains around a skylight
- Ceiling stains that grow after rain
- Damp ceilings under a flat roof
- A leak that comes and goes with the weather
If you run a business near Harlequin Centre, a quick answer on where water is coming in keeps a business running.
What to check before booking
- Whether any drone flown is registered with the CAA
- What happens after the report arrives
- How soon the report will arrive
- What’s outside the scope of the survey
Tips from our surveys
A few practical points come up again and again on our surveys. They apply to most roofs:
- Note the weather when the leak shows
- Keep water away from lights and sockets
- Keep a photo record of the damp patch
- Move stored items away from the hatch
Standard includes a follow-up consultation to talk the findings through, while Premium includes one in person. You can ask us about anything that is not clear.
Do not block the vents at the eaves. Good airflow reduces condensation, which is frequently mistaken for a leak. Keep insulation clear of the eaves.
