Arkley Flat Roof Survey
Not sure what state the flat roof is in? We carry out flat roof surveys in Arkley and across Greater London.
- Cracked or split membrane
- Gaps at upstands and abutments
- Leaks around rooflights
How the survey works
Photographs are taken throughout the visit, so you can see in the report what we found and where. Close-ups come from the safest viewpoint available, including by drone where it is applicable and the weather allows. Most surveys take about one to two hours for a small flat roof at home, and longer for a large commercial one. In a London conversion, the way into the loft space is frequently from a communal landing or the top flat. Where that’s the case, access needs agreeing with whoever controls that landing. Everything else is planned around the building, not the postcode.
- You send us the address and, for commercial roofs, an idea of the roof’s size.
- Inside, we look for signs of water under the roof where we can reach.
- The roof is inspected from every safe viewpoint, without walking on fragile surfaces.
- Each defect is photographed and its likely cause noted.
- The report explains the condition and recommends what to do first.
Getting ready for the survey
- If it isn’t your property yet, arrange access through the agent
- Tell us about any leaks, stains or damp patches you know of
- Make a note of anything you’d like us to look at
Book a survey
Most bookings start with a short call: call 07833 053749 or email us and we’ll ask a few questions about the roof. The price is agreed before a date is set.
Advice
Flat roof survey in Arkley: what you get
A flat roof does not shed water the way a pitched roof does. Because rain sits on it for longer, a small split, an open seam or a blocked outlet matters more. We check the surface, the falls, the upstands and the edge trims, and we note any sign that the deck below has got wet. The aim is to find problems before they show up as a stain on a ceiling. Common reasons to book are water getting in at rooflights and blistering in felt or asphalt, across mastic asphalt, GRP fibreglass and upstands and outlets.
Across London, flat roofs are everywhere, from back additions and dormers to roof terraces, blocks of flats and offices. Coverings range from felt and asphalt to EPDM rubber, GRP fibreglass and single-ply membranes, and each fails in its own way. In Arkley, as anywhere in London, the right approach depends on what the roof is made of. Many older flat roofs are felt or asphalt, and many newer ones EPDM rubber or GRP.
The report does not just list problems. For each finding, it explains what it is, why it matters and what we’d recommend.

Signs you need a flat roof survey in Arkley
Water that does not drain sits on the roof and speeds up wear. Blocked outlets, poor falls and a sagging deck are the usual causes. Where trees are close by, leaves and silt can block an outlet within a single autumn.
Typical things we are asked to look at include:
- Pools of water lying on the roof
- Signs of deflection in the roof deck
- Loose or cracked edge trims
- Blistering in felt or asphalt
Anyone responsible for a site like Whitings Hill Primary School will know that large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.
What to check before booking
- Are they insured for the work?
- Whether VAT is added on top
- Will they check the loft as well as the outside?
- What follow-up you get after the report
Tips from our surveys
Small things make a difference, both for the survey and for the roof itself. Some pointers:
- Check ceilings under the roof for damp patches
- Note where water lies after a downpour
- Limit foot traffic on the covering
- Keep records of when the roof was laid and what work has been done
If anything in the report is not clear, just ask us. Standard Surveys come with a follow-up consultation, and Premium Surveys with an in-person one, giving you a chance to go through what we found.
Clear leaves and silt from outlets and gutters, above all in autumn. A flat roof that drains well wears much more slowly.

Your questions about flat roof surveys in Arkley
How do I find out if my home in Arkley is listed?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. It matters most if you are planning to re-roof in a different material.
Will parking be an issue for a roof survey in Arkley?
It depends on the street. Where there are permit zones, a visitor permit or nearby pay-and-display bay works well.
How do you inspect a flat roof?
Only where it is safe to do so. Otherwise we use windows, vantage points and the spaces below, and the report says if any part couldn’t be seen. We don’t walk on fragile rooflights or sheeting.
Does the weather affect the survey?
Some surveys depend on the weather more than others. Drone flights need calm, dry weather, and thermal imaging works best after a sunny day, with a dry roof and little wind. We will rearrange with you if the weather is not right.
Do you need to get into the loft?
Yes, where the survey calls for it and there’s safe access. We look for staining, damp, daylight and signs of movement, as far as the space allows.
How long is the visit?
It usually takes about 1–2 hours for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. The written report follows by email.
Do you use drones?
Yes, where it is applicable. Flights depend on the weather on the day and airspace rules, and we check for restrictions near airports before flying. We are a CAA-registered drone operator.
Leave it or get it looked at?
On a commercial building, a flat roof leak can disrupt tenants, staff and stock. A planned survey lets you budget for work rather than deal with an emergency around the people who use the building. In a London terrace or conversion, a roof defect rarely stays your problem alone: failed flashings and blocked valley gutters can send water into more than one home. Finding it early keeps the work smaller.
Prices start from £150, including VAT, for a Basic Survey. Standard is from £250 and Premium from £400, both with VAT included. We confirm the exact price before you book.

What you can safely check yourself
You can learn a lot from the ground. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Please do not climb up for a closer look.
During heavy rain, look at the gutters from the ground or a window. Overflowing water can point to a blockage or a sagging run.
What affects the cost of flat roof surveys
Survey packages start from £150, inc. VAT. What you pay for your roof depends on:
- The package you choose: Basic, Standard or Premium
- If the survey needs thermal imaging or a drone
- Height and safe access
- The number of roofs, including extensions and garages
For a price for your roof in Arkley, phone 07833 053749 or send us an email and tell us about the roof. We will confirm the figure before booking.
Getting in touch
A little information up front helps. It helps to include:
- The kind of building and roof involved
- When you need the report by
- The reason for the survey, such as buying, a leak or storm damage
- Where water is showing inside, if it is
Prices start from £150, including VAT. What you pay depends on the roof’s size, access and the package, and you can ring 07833 053749 or email us to find out.
What a flat roof survey looks like in Arkley
The wider area around Arkley has a long history of building, with Wyllyotts Manor about 3.7 miles north-east. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and the council can say whether a home is in a conservation area. In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
If you own a rental within reach of Elstree & Borehamwood station, a flat roof over a rented flat is easy to forget until the tenant reports a leak. If you look after a shop, office or commercial unit, for example near Spires Shopping Centre, flat roofs over shops and units are easy to forget until water comes through a ceiling.
