Roof leak investigations for homes and businesses in Colney Heath
A leak that comes and goes can be the hardest to pin down. 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. We look for the clues it leaves behind, such as tide marks, stained timbers and damp underlay. Moisture readings show where materials are still wet. Common reasons to book are drips from nail tips in a cold loft and damp walls below an overflowing gutter, across slate and tile slopes, lead flashings and flat roof details.
Being in a small place like Colney Heath makes no difference to how a leak or storm damage is looked at: we simply plan the journey and access ahead. It helps to know where the water appears, in what weather, and what you’ve seen 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: your solicitor, the seller, your insurer, a roofer or the building’s managing agent.

Do you need a roof leak investigation in Colney Heath?
Chimneys can let water in by several routes. Water can enter through crumbling mortar, cracked flaunching, worn flashings or uncapped pots. The damp may appear on a chimney breast, a ceiling or in the loft.
People typically book a survey after spotting one of these:
- Damp on a chimney breast
- Water dripping from rafters or underlay
- Wet patches high on an inside wall
- A leak that comes and goes with the weather
Living close to North Mimms Park is pleasant, but mature trees mean leaves in gutters and valleys each autumn.
Before booking anyone
- Which viewpoints they use to see the roof
- Whether the loft space is looked at, where there is one
- Do they have a CAA Flyer ID and Operator ID for drone work?
- Whether VAT is added on top
Colney Heath: your questions answered
Will you come out to Colney Heath?
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.
Is my home in Colney Heath listed or in a conservation area?
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.
Is the repair included in the leak investigation?
A leak investigation finds and reports the likely source. The repair is not part of it. The report shows where the water gets in and what should be done, which whoever carries out the work can follow.
Is there anything I need to do ahead of the visit?
Note when the leak appears and what the weather was doing, and take photos. Clear access to the loft. If water is near any fittings, have an electrician check them.
Is it the same as a RICS Level 2 or Level 3 survey?
No. We check the roof, not the whole building, and it isn’t a RICS Level 2 or Level 3 survey. Many buyers have both.
How do I book a survey in Colney Heath?
To arrange a survey, call 07833 053749 or send us an email with the address, the type of property and what’s prompted the survey. We’ll confirm the price and agree a day with you.
Why doesn’t the damp patch line up with the hole?
Because water travels. It runs along rafters, battens or underlay before it drips, so the entry point is frequently well away from the mark. That is why we trace the route rather than patching above the stain.
Should I look at the roof myself first?
It helps to keep a record: when leaks happen, ground-level photos and any past roof work. Share it with us when booking and it will help the survey.
A DIY look is useful, but it is not a survey. From the ground, valleys, flashings and the backs of chimneys are often out of sight.
Surveys for landlords and agents in Colney Heath
Any of our surveys can be booked by landlords, agents and building managers in Colney Heath. For a price for a let property or a block, ring 07833 053749 or use the contact form.
For a freeholder or residents’ company, a roof report is a sound basis for a maintenance plan.
How it works
The visit normally starts outside and finishes in the loft: first the slopes, edges and gutters from every safe viewpoint, then the roof space where it can be reached. In total, it takes about 1–2 hours at most homes, and more on a big or complicated roof. In a hamlet or village like Colney Heath, a postcode does not always lead to the right gate, so a few directions are welcome. After that, the survey runs as it would anywhere.
- You pick a Basic, Standard or Premium Survey.
- A visit is booked for a weekday, Saturday or Sunday.
- 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
- Find any records of previous roof work
- Let us know where we can park nearby
- Make sure pets are kept safely away
How to book
We confirm the price for your survey before booking, so you know the cost up front. Roof leak investigation starts from £150, including VAT. For a price for your roof, phone 07833 053749 or email us.

What a roof leak investigation looks like in Colney Heath
With Hatfield House about 2.3 miles north-east, Colney Heath 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 any change of roofing material on a listed home needs checking with the council first. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. Each of these roof types has its own typical places for water to get in.
If you live in an older home near Church of St Mark, the leak may come from a chimney, a valley or tired lead rather than the covering itself. If you run a business near The Maltings, finding where water is getting in quickly keeps disruption down.
