Roof leak investigation in Monken Hadley
Our job is to find the likely source and tell you. The report shows, with photos, where we believe the water gets in and how it travels, and recommends what should be done. Whoever does the work then has a clear starting point. We find and report the source, and the repair itself is a separate job. Common reasons to book are wet patches high on an inside wall and a leak that comes and goes with the weather, on the roof space, valleys and parapet gutters and flat roof details.
In a London flat, water can travel some way before it shows, sometimes in a different flat from the one below the defect. Tracing it back matters, both for dealing with the cause and for any insurance claim. We check what we’re given access to in Monken Hadley, inside and out. Let us know when the water shows, and in what kind of weather.
The report records the leaking roof as we found it on the day. That makes it useful now and a handy reference later, for example when you want to check whether anything has changed.

Monken Hadley questions
Do you carry out roof surveys in Monken Hadley?
Yes, Monken Hadley is one of the places we work. Every survey there gets the same written report with photographs, and visits run on weekdays and weekends.
Does a conservation area affect roof work in Monken Hadley?
We can’t confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case, and councils can also use Article 4 directions.
Do you need to get into the loft?
If it is needed and safe to reach, yes. We look for staining, damp, daylight and signs of movement, as far as the space allows.
How soon will I get the report?
The Premium Survey report comes the same day, the Standard within 24–48 hours and the Basic within 48 hours. All of them come by email, ready to forward.
How do I book a survey in Monken Hadley?
It’s easiest to phone 07833 053749 or drop us an email. Give us the address and some details about the roof, and we’ll take it from there. Surveys run on weekdays and at weekends.
Will you fix the leak as part of this?
The investigation is about finding the cause. The repair isn’t part of it. You get a report with photos showing where the water is getting in and what needs attention.
What does the report include?
A written report with photos, explaining the condition of the leaking roof, any defects and our recommendations. The Standard Survey adds moisture detection and a structural check, and the Premium Survey adds thermal imaging, drone inspection where applicable and structural analysis.
Signs you need a roof leak investigation in Monken Hadley
Flashings are one of the commonest sources of roof leaks. Where a roof meets a chimney, a wall or a dormer, lead or mortar seals the joint. Once that seal cracks or lifts, water gets behind it.
Here are some of the things we see often:
- Water that shows only in certain storms
- Water dripping from rafters or underlay
- Leaks below a flat extension roof
- Damp underlay across a wide area
For businesses in and around places such as Spires Shopping Centre, a quick answer on where water is coming in keeps a business running.
Before you book any roof surveyor
- What’s outside the scope of the survey
- Which parts of the roof they’ll actually see
- Whether VAT is in the quoted price
- Is there a chance to talk the report through?
What affects the price in Monken Hadley
Prices vary from roof to roof, for these reasons:
- Extensions, dormers and garages with roofs of their own

Every price we give includes VAT. Roof leak investigation starts from £150, including VAT. You will know the price for your roof before you book.
Booking your survey
When you call or email, these details help:
- Whether there is a loft hatch, a shared roof or tricky access
- Your timetable, like an exchange date
- What made you get in touch
- The type of building and roof, such as pitched or flat
Surveys can be booked for weekdays, Saturdays or Sundays. To arrange a day that suits you, call 07833 053749 or drop us an email with the address and the days you’d prefer.
The survey, step by step
On the day, we start by asking what you’ve noticed and what you want to find out. After that, we check everything we can see safely. The survey typically takes about one to two hours, more where the leak is intermittent or the roof is large. In a London area like Monken Hadley, the main things to sort out are parking and access: let us know about parking, the floor the property is on, any shared entrance and loft access. On the day, the roof is looked at from the ground, from windows, from inside the loft space and from the roof where it’s safe.
- We start with your notes and photos of the leak.
- Inside, we look at the stain and the ceiling around it.
- In the loft, we follow any signs of water back towards the roof.
- We inspect the likely entry points outside, from the ground, windows and the roof where safe.
- We email a written report showing where the water most likely gets in.
How to prepare
- Make a note of anything you’d like us to look at
- Check pets are kept safely away
- Make sure we can get to the back of the property
Arrange a survey
Getting a price is simple: just ring 07833 053749 or use the contact form and give us some details about the property and we will explain which survey suits. The price is agreed up front.

Roof leak investigations in Monken Hadley: local notes
Historic houses such as Wyllyotts Manor, about 2.4 miles north, show how far back building in the area around Monken Hadley goes. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead. Further from the centre, London’s housing takes in interwar semis with hipped roofs in clay or concrete tiles as well as slate-roofed terraces. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Knowing the roof type helps narrow down where water may be getting in.
Homes near green spaces such as King George's Fields (Monken Hadley) can get more leaves in their gutters in autumn. If you live in an older home near Parish Church of St Mary the Virgin, leaks on older roofs often start at lead flashings, valleys or around old chimney stacks.

Different roofs, different checks
Chimney stacks
Water that gets in at the top can show up lower down. Open, unused pots let rain fall down the flue.
Flat roof upstands and outlets
Upstands seal the edge of a flat roof where it meets a wall. If it is too low, cracked or poorly dressed, water gets behind it.
Before and after the survey
Most of what helps is simple and safe from ground level. A few suggestions:
- Write down the wind direction and rain when it leaks
- Put a bucket under the drip and move valuables
- Clear the loft hatch so we can get in
- Mention any plumbing above the damp area
If condensation is the cause, we explain it, with recommendations on ventilation. It saves chasing a leak that isn’t there.
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.
