How a roof leak investigation works in Crayford
Older homes have more places for water to get in. Worn lead, tired valley linings and blocked parapet outlets are frequent causes. A central valley gutter on a butterfly roof frequently turns out to be the source. Parapet walls and their gutters are looked at from wherever it is safe. The findings are recorded with photos. If you’re worried about damp underlay across a wide area and wet patches high on an inside wall, a survey will tell you what’s going on, whatever the roof.
In a smaller place like Crayford, some roofs face open ground, so wind and driving rain find any weakness in ridges, verges and flashings. A leak that only appears in certain weather often points to an exposed detail. Tell us when it happens when you contact us. The gutters on the most exposed side can overflow too.
Where we can’t see part of the leaking roof, the report says so. You will know exactly what was inspected and what wasn’t.

How the survey changes by roof type
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.
Chimney stacks
A stack has several possible ways in for rain. Each is checked from every safe vantage point.
Crayford questions
Do you cover smaller places like Crayford?
Yes, we do. We survey roofs across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you carry out roof surveys in Crayford?
Yes, Crayford is within the area we cover. We work right across London and South East England. You can call 07833 053749 or send us an email with the address and a few details.
Will you definitely find the leak?
We cannot promise it. 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.
Do you use thermal imaging to find leaks?
Thermal imaging is used where it’s useful, and it is included in our Premium Survey. It picks up temperature patterns rather than water, so anything it suggests is checked with moisture readings.
Can a leak be traced on a dry day?
Frequently, yes. Stains, tide marks, damp timbers and moisture readings typically point the way. Some leaks only show in particular weather, so your photos and notes from wet days are very useful.
What’s the best way to book?
Just call 07833 053749 or send us an email. After a few questions, we confirm the price and fix a day, weekday or weekend.
Is this an asbestos survey?
No. We do not carry out asbestos surveys or testing. We flag materials that could contain asbestos, like cement sheets or soffits on pre-2000 buildings.
Useful tips for Crayford property owners
A few practical points come up again and again on our surveys. They’re worth knowing whatever the roof:
- Let us know about any past repairs to the roof
- Do not climb onto the roof to look
- Check whether pipes or tanks run near the stain
- Keep water away from lights and sockets
Any roofer you ask to quote can work from the report. The photos show the defects and where they are, so the repair is aimed at the cause.
Plan a roof survey every few years. They’re where most leaks start, and catching wear early keeps water out.

Crayford roofs and the weather
Older houses across Kent often have handmade clay or peg tiles, and many have tile-hung walls. The county’s older buildings also include oast houses and timber-framed Wealden hall houses. Knowing the roof type helps narrow down where water may be getting in. Hall Place and Gardens, about 0.9 miles west, is one of the historic houses in the wider area around Crayford. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and any change of roofing material on a listed home needs checking with the council first.
If you own one of the older houses in the streets near Church of St Paulinus, leaks on older roofs often start at lead flashings, valleys or around old chimney stacks. Anyone responsible for a site like Wentworth Primary School will know that a leak through a large roof is often found some distance from where the water shows inside. If you live near a park such as Braeburn Park, or anywhere with mature trees, autumn leaves can block gutters and valleys, and an overflowing gutter soon means a wet wall.
Crayford is about 2 miles west of Dartford, in Kent. Houses, flats, blocks and commercial buildings in Crayford can all book roof leak investigations. We cover towns and villages across Kent, from the larger towns to small villages. London is in our area too.

How the survey works
Time on site depends on the size and shape of the roof, but as a rough guide the survey takes about 1–2 hours for most homes, though a hard-to-trace leak can take longer. You’re welcome to ask questions while we’re there. With a bit of garden around a house, as there often is around Crayford, the roof can be viewed from several angles. Mention any side of the property we cannot get to. The loft, where there is safe access, completes the picture.
- You pick a Basic, Standard or Premium Survey.
- We agree a date, including weekends.
- The investigation works from the stain back to the roof.
- Moisture detection and thermal imaging are used where your package includes them and they help.
- You get photos, the likely cause and clear recommendations.
How to prepare
- Unlock side gates and any roof access doors
- Keep pets in another room
- For flats, make sure roof access has been agreed

Advice
DIY checks: what’s safe
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it.
If you have a loft with safe access, take a look inside. Take a torch and only step on boards or joists, checking for stains, damp wood or chinks of daylight.
Honest limits
No survey can tell you everything, and it’s better to know them up front. Bear these in mind:
- What’s under the covering or behind the plaster
- Leaks from plumbing, tanks or pipework rather than the roof
- The repair itself (the investigation finds and reports the cause)
If you’re not sure which survey you need, ring 07833 053749 or send us an email and we will give you a straight answer. What a survey covers and does not.

What happens if roof problems are left?
A small drip today can be a bigger leak after the next storm. Each storm can open a gap a little more. Tracing it now lets you plan the work rather than react to it. Arranging work in a smaller place like Crayford is easier with notice than in an emergency. Knowing early gives you time to get the right people in.
