Monk's Gate Roof Leak Investigation
Need a roof leak investigation in Monk's Gate? We can help, with findings in writing and pictures to back them up. Book a weekday or weekend visit.

- Damp on a chimney breast
- A leak that comes and goes with the weather
DIY checks: what’s safe
A DIY look is useful, but it is not a survey. You will not see flashings, valleys or the backs of chimneys properly from ground level.
The one thing to avoid is getting up close. Slates, tiles, flat roofs and rooflights can give way, and falls from height are serious. That part is for a survey.
How a roof leak investigation works in Monk's Gate
Water is good at hiding where it gets in. It can run along a rafter, a batten or the underlay before it drips, so the stain on your ceiling is seldom right under the hole. We follow it back towards where it starts, one likely route at a time. A repair aimed only at the stain can miss the cause entirely. Tracing the route first means any work can be aimed at the right place. If you’ve noticed staining where a gutter or parapet meets the wall and water dripping from rafters or underlay, we can find out what’s behind it, whatever the roof.
Somewhere as small as Monk's Gate, older roofs have frequently been repaired many times. That makes it hard to tell new damage from old wear, which matters if you’re thinking of an insurance claim. The report says what was seen and what it points to. Damp in old walls and timbers is slow to dry, so the sooner the cause is found the better.
Report times depend on the survey you book: the Basic Survey within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey on the same day.

Leave it or get it looked at?
Leaks tend to get worse, not better. Wind lifts loose slates further and gaps widen. Tracing it now lets you plan the work rather than react to it. In a place like Monk's Gate, a barn or garage roof left to fail puts whatever is inside at risk. A quick look before winter can save a lot.
Roof leak investigation starts from £150, including VAT. The final price depends on the size and height of the roof, how it can be seen safely and which survey you book.

Questions from Monk's Gate
Do you cover smaller places like Monk's Gate?
Yes, Monk's Gate is on our map. A small place gets exactly the same survey as a big one.
Do you cover Monk's Gate?
Yes, Monk's Gate is within the area we cover. We cover the whole of London and South East England. Just phone 07833 053749 or email us and tell us about the property.
Do you climb onto every roof?
Not always. Some roofs are too steep or fragile to walk on safely. We use safe viewpoints, the loft space and a drone where it applies, and the report records anything we couldn’t see.
What happens after the survey?
The report arrives by email, with photos and clear recommendations. With Standard there is a follow-up consultation; with Premium, an in-person consultation, so you can talk the findings through.
Could my leak actually be condensation?
It is a common question. A leak usually shows in one area and follows rain, while condensation is often spread out and worse in cold weather. The report explains which it looks like and what to do.
Is it the same as a RICS Level 2 or Level 3 survey?
No. It’s 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. The report includes photographs of what we found, so you can see each point for yourself.
When you need someone else
A survey is a careful look at the leaking roof, but it cannot do everything. Its limits include:
- Plumbing leaks that look like roof leaks
- The repair itself (the investigation finds and reports the cause)
- Whether rotten timbers meet design loads
If in doubt, ring 07833 053749 or drop us an email and we will suggest the right survey before you book. What a survey covers and does not.

Wind, rain and roofs in Monk's Gate
Handmade clay tiles and tile-hung upper walls are typical of older Sussex houses. Some old buildings in Sussex have Horsham stone slab roofs. Each of these roof types has its own typical places for water to get in. Listing and conservation areas can both shape what roof work is allowed on an older home. Your council and Historic England’s list will tell you where you stand, before anyone quotes for re-roofing.
Anyone responsible for a site like St Andrew's CofE Primary School will know that tracing a leak on a big roof starts with where the water appears and works back. The streets around a church such as Church of the Good Shepherd are often among the oldest in a place, and if your home is one of the older ones nearby, the leak may come from a chimney, a valley or tired lead rather than the covering itself. Living close to Leonardslee is pleasant, but mature trees mean leaves in gutters and valleys each autumn, and blocked gutters overflow and soak walls.

How it works
Before we start, tell us why you’ve booked: a purchase, a leak, a storm, new work or simply peace of mind. It helps us focus on what matters most to you. The visit typically takes between one and two hours, more where the leak is intermittent or the roof is large. Around Monk's Gate, older homes can have small or awkward roof spaces, so it’s useful to know whether there’s a loft hatch and how easy it is to reach. We only go where it is safe.
- We start with your notes and photos of the leak.
- We examine the damp area and the rooms near it.
- From the roof space, we trace the water’s route where there is safe access.
- 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
- Keep pets in another room
- Jot down any questions you want answered
- If the roof is shared, arrange access with whoever manages the building

Related advice
Before and after the survey
These tips come from what we see on roofs every week:
- Don’t touch fittings that water is reaching
- Note the weather when the leak shows
- Tell us if there are tanks or pipes in the loft
- Mention earlier attempts to fix the leak
Once the work is done, hold on to the report. If the leak returns, it is a useful record of what was found, which makes the next step quicker.
Have leaves and moss cleared from gutters, valleys and outlets, ideally once the leaves have fallen. Many leaks start with a blocked outlet. Use a professional rather than climbing up yourself.
