How a roof leak investigation works in Broad Colney
Some leaks only appear in certain weather. Driving rain from one direction, melting snow or a gutter that overflows in a downpour can all set it off. 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. If you are worried about wet patches on loft insulation and damp on a chimney breast, we can find out what’s behind it, on the roof space, flat roof details and rooflights and dormers alike.
Somewhere as small as Broad Colney, older roofs have frequently been repaired many times. A new leak may be fresh damage or the latest sign of long-term wear, which matters if you’re thinking of an insurance claim. We check 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.
It is not only a list of defects. For each finding, it explains what it is, why it matters and what we’d recommend, so you can plan your next steps.

Broad Colney roofs and the weather
High Elms Manor, about 4.1 miles west, is one of the historic houses in the wider area around Broad Colney. If yours is one of the older homes, expect a mix of original materials and later repairs on the roof, and any change of roofing material on a listed home needs checking with the council first. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. The covering and its details give the first clues when tracing where water is coming from.
For landlords with property near Park Street station, tracing a leak quickly matters when a tenant is living with it. Shop and office owners around The Maltings may find that a quick answer on where water is coming in keeps a business running. For an older house near a landmark such as Church of St Peter, lead flashings, valleys and old chimneys are typical places for water to get in.
Broad Colney is about 3 miles south-east of St Albans, in Hertfordshire. We survey roofs in Broad Colney and the rest of Hertfordshire, as part of our work across London and South East England. Our Hertfordshire coverage includes Broad Colney and the places around it. London is in our area too.
Roof leak investigations in AL2 are booked the same way as anywhere else. Nearby, we also carry out roof leak investigations in London Colney (1 mile north), Shenleybury (1 mile south-east), Tyttenhanger (2 miles north), Sleapshyde (3 miles north-east) and Colney Heath (3 miles north-east).

Tips that help
These tips come from what we see on roofs every week:
- Do not touch fittings that water is reaching
- Check whether pipes or tanks run near the stain
- Let us know about any past repairs to the roof
- Do not climb onto the roof to look
Once the work is done, hold on to the report. If water appears again, it shows what was found before.
Have flashings and flat roofs looked at every few years. They’re where most leaks start, and wear is easier to deal with before water gets in.
How the survey works
We look at the roof from outside and, where it’s relevant and there’s safe access, from inside the roof space too. Inside, we look for staining, damp, gaps and signs of movement. The whole visit normally takes about one to two hours at most homes, and longer for a large or complex roof. Somewhere as small as Broad Colney, access is often the only tricky part. Mention any outbuildings, barns or garages you want included, and anything about the roof you already know. Weekday and weekend visits are available.
- We help you choose the package that suits the leak.
- A visit is booked for a weekday, Saturday or Sunday.
- We inspect inside and out, starting from the stain.
- Moisture detection and thermal imaging are used where your package includes them and they help.
- You get photos, the likely cause and clear recommendations.
Before the survey
- Tell us where we can park nearby
- If it isn’t your property yet, arrange access through the agent
- Keep pets inside or away from the areas we are looking at
Getting a price

Advice
Questions from Broad Colney
Will you come out to Broad Colney?
Yes, smaller places are covered as well as towns. We survey roofs across London and the South East. Just mention lanes, gates or anything else about the route as you book.
Do you cover Broad Colney?
Yes, Broad Colney is within the area we cover. Our area covers London and South East England. Just call 07833 053749 or use the contact form and let us know about the property.
Is it a leak or condensation?
Condensation can look very like a leak. Drips from nail tips, damp underlay over a wide area and poor loft ventilation point towards condensation. We check the pattern, take moisture readings and tell you which is more likely.
When does the report arrive?
Basic reports arrive within 48 hours, Standard reports in 24–48 hours and Premium reports on the same day. All of them come by email.
What’s in the survey report?
A written report with photos, covering the condition of the leaking roof, the defects we found and what we recommend. Standard adds moisture detection and a structural check; Premium adds thermal imaging, drone inspection where applicable and structural analysis.
Do you test for asbestos?
No. Our report may flag materials that could contain asbestos, but only a specialist asbestos surveyor can confirm it. Buildings built or refurbished before 2000 may contain it.
What insurance do you have?
We hold professional indemnity and public liability insurance.
What we look for on each type of roof
Parapet and box gutters
A butterfly roof drains to a central valley gutter. Problems there frequently show in the rooms on the top floor.
Valleys
Stains from a valley leak frequently show some distance off. We trace the route from the loft where there is safe access.

Why get it checked now?
Damp in a ceiling or loft can lead to mould. It’s unpleasant, and it is harder to deal with once established. Finding the leak comes first. Where a roof is exposed, as many are in small places like Broad Colney, driving rain gets into any weakness, and damp in older walls is slow to dry out.
A small, low roof with good viewpoints takes less time than a tall, complicated one, and the package you pick makes a difference too. The price is always agreed first.
What you get with us
- Insured for professional indemnity and public liability
- Thermal imaging and drones used where they help
- CAA-registered drone operator (Flyer ID and Operator ID)
- Clear package prices, with VAT included

What affects the cost of roof leak investigations
What a survey costs depends on the time and equipment it needs. The main factors are:

- Whether thermal imaging or a drone is needed
- Chimneys, valleys, parapets and other details
The Premium Survey includes thermal imaging and drone inspection where applicable, from £400 inc. VAT. We’ll tell you which package suits the questions you have.
