Roof leak investigation in Moor Park: what you get

We use moisture detection and thermal imaging where they help. Moisture readings show which materials are wet. A thermal camera shows patterns of temperature rather than water, so we confirm what it suggests with moisture readings. Thermal imaging is part of the Premium Survey, and moisture detection comes with Standard. The best thermal results come after a sunny day, with a dry roof and little wind. If you’ve noticed water coming in around a roof light or dormer and brown rings on upstairs ceilings, we can find out what’s behind it, whatever the roof.

In London, leaks often start somewhere hidden: the valley gutter in a butterfly roof, a parapet gutter, a chimney flashing or the flat roof over a rear extension. Whether you are tracing a leak or recording storm damage in Moor Park, those are among the first places to look. Water from a hidden gutter can run along joists and show up a room or two away.

Report times depend on the survey you book: Basic within 48 hours, Standard in 24–48 hours and Premium the same day.

Should I look at the roof myself first?

A lot can be seen from ground level. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Never climb onto the roof to look.

After strong wind, take a look from the pavement or garden: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Do not go up yourself.

How the survey works

We don’t take risks to get a closer look. Everything that can safely be seen is inspected, and if part of the roof cannot be seen, the report says so. Most visits take about 1–2 hours for most homes, though a hard-to-trace leak can take longer. London terraces rarely offer a view of the whole roof from one spot, so a visit in Moor Park moves between viewpoints: the pavement, upstairs windows, the loft and any safe spot at the back. Shared stairs or a basement flat? Let us know who holds the keys.

  1. We start with your notes and photos of the leak.
  2. Inside, we look at the stain and the ceiling around it.
  3. From the loft space, we trace the water’s route where there’s safe access.
  4. We inspect the likely entry points outside, from ground level, windows and the roof where safe.
  5. You receive a report with the likely source, photos and recommendations.

Preparing for the visit

  • Make sure the loft hatch can be reached
  • Keep pets inside or away from the areas we are looking at
  • Unlock side gates and any roof access doors

Booking a survey

Moor Park: your questions answered

How do I find out if my home in Moor Park is listed?

We cannot confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case.

Do you cover Moor Park?

Yes. We cover the whole of London and South East England, and Moor Park is part of that. You can phone 07833 053749 or email us with the address and a few details, and we will talk through which survey suits.

Can you inspect my roof with a drone?

Yes, where it’s applicable. Our sub-250g drone is flown by a CAA-registered operator with a Flyer ID and Operator ID, and every flight depends on the airspace and the weather.

Can you always find the source?

We cannot promise it. Some leaks hide well, especially those that need wind-driven rain. If we can’t be sure, the report ranks the possible sources.

Is it a structural engineer’s report?

No. Visible signs such as deflection or sagging are recorded, but calculations and an engineer’s opinion are outside what we do. The report will say if you need an engineer.

Do you carry out surveys on Saturdays and Sundays?

Visits run seven days a week in the daytime, which suits people who work during the week. Just say which days work for you.

Does this replace a RICS home survey?

No. This is a survey of the roof only, and it is not a RICS Level 2 or Level 3 survey. Many buyers have both.

Rented homes, blocks and businesses

Landlords and letting agents in Moor Park book surveys as well as homeowners. The report gives you a dated record of the leaking roof, with photographs, which helps you plan work between tenancies.

Landlords, agents and building managers in Moor Park and across Greater London can book any of our surveys. To discuss a property or a block, call 07833 053749 or drop us an email.

What a roof leak investigation looks like in Moor Park

About 3.9 miles south-east lies Headstone Manor, a reminder of how long the area around Moor Park has been built on. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs. Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of clay or concrete tiles. If your home in Moor Park is one of them, bay roofs, hips and later dormers each have their own details. The covering and its details give the first clues when tracing where water is coming from.

For an older house near a landmark such as Holy Trinity Church, leaks on older roofs often start at lead flashings, valleys or around old chimney stacks. For site and facilities teams at buildings such as St Martins School Northwood, a leak through a large roof is frequently found some distance from where the water shows inside.

Moor Park is about 2 miles south-east of Rickmansworth, in Greater London.

Our area takes in places right across Greater London, large and small. Our London page covers surveys nearby.

Honest limits

It is a careful look at the leaking roof, not the whole story. Its limits include:

  • Carrying out the fix
  • Water from pipes, tanks or heating systems
  • A structural engineer’s report

If in doubt, ring 07833 053749 or email us and we will recommend the right survey. What our survey covers.

What we check

  • Rooflights and dormers
  • Chimney stacks
  • Lead flashings
  • The roof space
  • Valleys and parapet gutters
  • Slate and tile slopes
  • Flat roof details

What we are asked to look at in Moor Park

When a slate slips or a tile cracks, the underlay takes the water. Ageing felt underlay eventually tears and lets water through, while some very old roofs have nothing under the coverings. Corroded nails, known as ‘nail fatigue’, are a frequent cause on slate roofs.

It is worth booking a survey if you’ve seen:

  • Damp walls below an overflowing gutter
  • Damp ceilings under a flat roof
  • Damp patches next to the stack
  • Water dripping from rafters or underlay

If you live near a park such as King George V Playing Fields, or anywhere with mature trees, autumn leaves can block gutters and valleys, and blocked gutters overflow and soak walls.

Before booking any roof surveyor

  • What the report includes, and whether it has photographs
  • If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
  • Whether you can ask questions once you have the report
  • What the survey won’t cover

What a good roof survey covers

Tips from our surveys

Most of what helps is simple and safe from the ground. A few suggestions:

  • Put a bucket under the drip and move valuables
  • Keep water away from lights and sockets
  • Check whether pipes or tanks run near the stain
  • Move stored items away from the hatch

If there are several possible sources, we list them in order of likelihood. Recommendations are prioritised by urgency where relevant, so you know what to deal with first.

Plan a roof survey every few years. Flashings, valleys and flat roof details are frequent weak points, and catching wear early keeps water out.
