Monken Hadley: your questions answered
Will parking be an issue for a roof survey in Monken Hadley?
It depends on the street. If Monken Hadley has controlled parking where you are, a visitor permit is the easiest answer.
Does a conservation area affect roof work in Monken Hadley?
Start with Historic England’s list for listing and your council for conservation areas. It is worth checking before planning roof work, as both can affect what’s allowed.
Can you find where water is getting through my flat roof?
Our survey looks across the whole roof, not only above the stain. Splits, open laps, upstands, outlets and rooflights are all checked. If the cause can’t be seen, we’ll say so and suggest what would help.
How experienced are you?
More than 5,000 surveys over 20+ years.
Will I get photos?
Yes. Photographs are taken throughout the survey, and the report uses them to show each finding.
Will you check the loft?
Where it is relevant to the survey and there’s safe access, yes. Please clear anything stored under the hatch, and if the loft can’t be reached safely, the report says so.
How long does the survey take?
Most surveys take about 1–2 hours for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. We will confirm the timing as you book.
Flat roof survey in Monken Hadley
Each type of flat roof has its own weak points. Built-up felt tends to blister and crack, asphalt crazes and splits, EPDM can lift at its laps, and GRP can crack at board joints and edge trims. Single-ply PVC and TPO roofs are checked at their welds, edges and fixings. Knowing what you have and how it is doing helps you plan what comes next. We are frequently asked to look into pools of water lying on the roof and damaged trims at the roof edge, on GRP fibreglass, single-ply membranes and EPDM rubber.
Water getting through a flat roof in London can travel under the covering and appear some way from the hole. Upstands against parapets, outlets and the edge where flat meets pitched are common entry points. In a block or conversion in Monken Hadley, the flat roof is often a shared part of the building.
What you get is a clear record of the flat roof on the day we saw it. That makes it useful now and a handy reference later, for example when you want to check whether anything has changed.

What happens if roof problems are left?
Before replacing a flat roof, it is useful to know if you really need to. Sometimes a few details are to blame, and sometimes the covering has simply had its day. Our report gives you the evidence to discuss with a roofer. Blocked gutters and hoppers on London houses overflow and soak brickwork, which can lead to damp inside. A blocked outlet ignored for a winter or two can mean damp walls inside.
All our prices include VAT. Our price is from £150, including VAT. We confirm the exact price before booking.

Common roof problems in Monken Hadley
Ponding keeps the covering wet and wears it faster. It normally comes from poor falls, a blocked outlet or a deck that has dipped. Where trees are close by, leaves and silt can block an outlet within a single autumn.
People usually book a survey when they’ve noticed something like this:
- Upstands pulling away from walls
- Failed seals around rooflight kerbs
- A sagging deck under the covering
- Splits, cracks and crazing
If your home is one of the older ones in the streets near Parish Church of St Mary the Virgin, the flat roofs on later extensions tend to wear out long before the main roof.
Questions to ask before you book
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- Are they insured for the work?
- Which viewpoints they use to see the roof
- Their track record with similar roofs

Flat roof surveys around Monken Hadley
Outer London has a good many Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, often with hipped roofs in clay or concrete tiles. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Mixed in with those pitched roofs are plenty of flat ones, over rear extensions, dormers, garages and shops. With Wyllyotts Manor about 2.4 miles north, Monken Hadley 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.
If you look after a building such as Monken Hadley CofE Primary School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season. For a London address like Monken Hadley, it is useful to know about controlled parking before the day, along with any off-street space.

The survey, step by step
After the inspection, everything we found is written up as a photo-illustrated written report. On timing, most surveys take roughly 1–2 hours for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. In Monken Hadley, as in much of London, a good many properties are flats or terraces without side access, so rear slopes are viewed from windows, the loft or, where a flight is allowed, by drone. If the building has a managing agent or access rules, let us know when you book.
- We agree the roof to be surveyed, its use and any leaks you know about.
- The roof is viewed from safe positions, including the roof itself where that is safe.
- The covering is checked for wear, splits, blisters and standing water.
- Upstands, outlets, edge trims and rooflights are checked and photographed.
- The report, with photographs and recommendations, comes to you by email.
How to prepare
- Check the loft hatch can be reached
- Let us know where we can park nearby
- Agree roof access with the managing agent if it’s shared
Arrange a survey
Buyers should book once an offer has been accepted, so there is time to use the report before exchange. For any other survey, just phone 07833 053749 or drop us an email when you’re ready.
