About our roof leak investigation in Colney Street
We investigate roof leaks in Colney Street and across London and South East England. We visit on any day of the week. The investigation covers inside and out, from the stain to the likely entry points. You get a photo-illustrated written report and recommendations. If it is leaking right now, contain the water and keep it clear of electrics, and then phone 07833 053749 or email us. If you are worried about leaks at a dormer or roof window and damp walls below an overflowing gutter, a survey will tell you what’s going on, on lead flashings, chimney stacks and valleys and parapet gutters alike.
In a village or hamlet like Colney Street, older cottages and farmhouses often have roofs that have been patched over many years. A new leak may be fresh damage or the latest sign of long-term wear, and the difference matters, particularly to an insurer. We look at what can safely be seen and set out what we find. Older walls and timbers hold water for a long time, so it is worth finding the cause soon.
With the Standard Survey, you also get moisture detection, a structural check and a follow-up consultation. The Premium Survey adds thermal imaging, drone inspection where it applies, structural analysis and an in-person consultation.

Honest limits
Our findings are based on what we can see safely on the day, so some things are outside what a survey can do:
- Water from pipes, tanks or heating systems
- Faults hidden behind ceilings or boarding
- The repair itself (the investigation finds and reports the cause)
If in doubt, phone 07833 053749 or send us an email and we’ll suggest the right survey before you book. The full list of what we check.

Different roofs, different checks
Chimney stacks
Our chimney check is a visual inspection of the stack, and it is not a flue or gas safety check.
Flat roof upstands and outlets
Outlets drain a flat roof. When one blocks, water ponds and finds any weak spot. Outlets and the area around them are checked.
Surveys for landlords and agents in Colney Street
A roof problem in a let property affects your tenants as well as the building. A survey shows what needs attention, so you can plan the work with less disruption.
Managing agents and residents’ management companies use roof surveys to plan maintenance. Recommendations are set out in order of urgency where relevant.
Colney Street: your questions answered
Will you come out to Colney Street?
Yes, Colney Street is covered. Our area covers London and South East England, from towns to the smallest villages. The journey is planned ahead, so it is useful to know about access.
Is Colney Street in the area you cover?
Yes, Colney Street is within the area we cover. We work right across London and South East England. Just phone 07833 053749 or drop us an email and let us know about the property.
Do you test for asbestos?
No. Asbestos surveys and testing are not part of what we do. We flag materials that could contain asbestos, like cement sheets or soffits on pre-2000 buildings.
Can you give me structural calculations?
No. Visible signs such as deflection or sagging are recorded, but we don’t provide calculations or an engineer’s opinion. If one is needed, the report says so.
What’s in the survey report?
Written findings with photographs, covering the condition of the leaking roof, the defects we found and what we recommend, with the most urgent first where relevant. Standard adds moisture detection and a structural check; Premium adds thermal imaging, drone inspection where it applies and structural analysis.
When does the report arrive?
That depends on the survey you book: the Basic Survey report arrives within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey the same day. Reports are sent by email.
What should I do before you arrive?
Make sure the loft can be reached. Have any photos of the leak ready, and tell us about past repairs. In the meantime, catch the water and keep it clear of lights and sockets.
Leaks and storm damage in Colney Street
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. Each of these roof types has its own typical places for water to get in. The wider area around Colney Street has a long history of building, with High Elms Manor about 2.9 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.
If you let a flat or house near How Wood station, a clear finding on where water gets in helps you brief a roofer straight away. Take an older house close to Church of the Holy Trinity: water on an older roof tends to find its way in at the lead, the valleys or the chimney. Anyone responsible for a site like Park Street Church of England Voluntary Aided Primary School will know that on a building that size, finding the source of a drip means looking well beyond the stain.

Leave it or get it looked at?
A leak near lights or wiring needs attention quickly. If water is reaching a light fitting or switch, keep clear of it and have an electrician check it. Finding where the water is getting in should follow right away. Matching old materials, such as handmade tiles or stone slates, can take time to source. That’s one more reason to find defects before they become urgent.
The Premium Survey includes thermal imaging and drone inspection where applicable, which starts from £400, with VAT included. We can help you choose the package that fits what you want to find out.

Tips from our surveys
There is plenty you can do without going near the roof. Here’s what helps most:
- Take dated photos of the leak
- Protect furniture and flooring under the leak
- Move stored items away from the hatch
- Stay off ladders and the roof
If condensation is the cause, we explain it, with recommendations on ventilation. It saves chasing a leak that isn’t there.
Have leaves and moss cleared from gutters, valleys and outlets, especially in autumn. Blocked outlets on parapet and flat roofs cause many leaks. Use a professional rather than climbing up yourself.

What we do, step by step
A survey visit follows a simple order: we hear what you’ve seen, look at the roof from every safe viewpoint, take photos as we go and make notes for the report. It normally takes about one to two hours at most homes, and more on a big or complicated roof. Rural addresses near Colney Street can be hard to find from a postcode alone, so a few directions, or a note of a nearby landmark, help us arrive on time. After that, the survey runs as it would anywhere.
- We start with what you’ve seen: where the stain is and when it gets worse.
- The visit starts indoors, at the stain and in the loft.
- Likely entry points outside are checked, from flashings and valleys to gutters and outlets.
- Moisture readings and thermal imaging are used where they help.
- We email a report with photos, the likely entry point and recommendations.
Getting ready for the survey
- Check we can get to the back of the property
- Tell us where we can park nearby
- Have any paperwork from past roof work to hand
