The survey, step by step
A survey visit follows a simple order: 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. Most visits take an hour or two for most homes, though a hard-to-trace leak can take longer. Somewhere as small as South Harefield, access is often 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 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 each safe vantage point.
- You receive a report with the likely source, photos and recommendations.
Before we arrive
- Make sure pets are kept safely away
- Have keys ready for side gates, garages or roof access doors
- Mention any parking restrictions on your street
How to book
Most bookings start with a short call: ring 07833 053749 or drop us an email, and we’ll ask about the building and what you need. The price is agreed before a date is set.

About our roof leak investigation in South Harefield
Our roof leak investigations cover South Harefield and the wider South East. We visit on any day of the week. The investigation covers inside and out, from the stain to the likely entry points. The findings come in a written report with photos. If water is coming in now, catch it in a bucket and keep it away from lights and sockets, and then phone 07833 053749 or drop us an email to arrange a visit. If you’ve noticed water that shows only in certain storms and water through the ceiling under a flat roof, we can find out what’s behind it, on chimney stacks, the roof space and flat roof details alike.
Somewhere as small as South Harefield, older roofs have often been repaired many times. A new leak may be fresh damage or the latest sign of long-term wear, and the difference matters, especially to an insurer. We look at what can safely be seen and set out what we find. Damp in old walls and timbers is slow to dry, so the sooner the cause is found the better.
The report records the leaking roof as we found it on the day. It is useful straight away, and a good reference for later.

Signs you need a roof leak investigation in South Harefield
Blocked gutters can look like a roof leak. Parapet and box gutters are the worst for this, because when they block, water backs up and runs inside.
These are some of the problems a survey can pick up:
- Staining where a gutter or parapet meets the wall
- Drips in the loft during heavy rain
- Leaks that appear only in driving rain
- Water through the ceiling under a flat roof
If you live in an older home near Church of St Mary the Virgin, lead flashings, valleys and old chimneys are typical places for water to get in.

Wind, rain and roofs in South Harefield
A number of Buckinghamshire villages keep thatched roofs on their older buildings. Older houses in the South East frequently have slate or clay tile roofs, while many later estates have concrete tiles. Where water gets in depends a good deal on what the roof is made of and how it’s detailed. Ickenham Hall, about 2.7 miles south-east, is one of the historic houses in the wider area around South Harefield. Older homes in the wider area often have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years, and a listed home or one in a conservation area may need consent for changes of material.
Take a building like Harefield Infant School: tracing a leak on a big roof starts with where the water appears and works back. If you let a flat or house near Denham station, tracing a leak quickly matters when a tenant is living with it.

South Harefield questions
Do you carry out roof surveys in South Harefield?
Yes. We work right across London and the South East, and South Harefield is part of that. Just ring 07833 053749 or send us an email and let us know about the property.
How do I find out if my home in South Harefield is listed?
Your council is the best source, with Historic England’s list for listed buildings. A change of roofing material may need consent in either case, and councils can also use Article 4 directions.
Can you survey a shared roof?
Yes, once whoever controls the roof agrees access. On a shared roof we can only inspect the parts we’re allowed to reach, and the report makes that clear.
Can you survey at the weekend?
Surveys run on weekdays and at weekends. To find a day that suits you, phone 07833 053749 or use the contact form.
Is it the same as a RICS Level 2 or Level 3 survey?
No. It is a specialist roof survey, not a RICS Level 2 or Level 3 building survey. It focuses on the roof, so it sits alongside a building survey rather than replacing it.
Will you photograph what you find?
Yes. Photos are taken throughout the survey, and they go into the written report alongside our recommendations.
Is thermal imaging part of a leak investigation?
It can, when the conditions are right. The best results come after a sunny day, on a dry roof with little wind. Wet insulation holds heat longer than dry, which can show up on the image. We always check what it shows with moisture readings.
Tips from our surveys
Here are a few things we’d tell any owner, before and after a survey:
- Keep water away from lights and sockets
- Check the loft is accessible
- Keep a photo record of the damp patch
- Don’t climb onto the roof to look
If the leak turns out to be condensation, the report says so, and suggest how the loft space could be better ventilated. That avoids roof work that wouldn’t help.
Have flashings and flat roofs looked at every few years. Flashings, valleys and flat roof details are frequent weak points, and wear is easier to deal with before water gets in.

What you can safely check yourself
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. Don’t go up yourself.
What you cannot do safely is get up close. Slates, tiles, flat roofs and rooflights can give way, and a fall can be serious. That part is for a survey.
What a roof leak investigation does not cover
To be straight with you, a roof survey has limits:
- Defects hidden under coverings or inside walls without opening up
- Putting the leak right
- Leaks that only appear in weather we can’t recreate
