Flat roof survey in Mugswell: what you get
Flat roofs deal with rain in a very different way from pitched ones. Because rain sits on it for longer, a small split, an open seam or a blocked outlet matters more. The surface, the falls, the upstands and the trims are all looked at closely, and we look for signs that water has reached the deck. The aim is to find problems before they show up as a stain on a ceiling. We survey EPDM rubber, GRP fibreglass and upstands and outlets, and common reasons people get in touch are splits and cracks in the covering and dips that suggest the deck is deflecting.
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 Mugswell, as anywhere in London, the right approach depends on what the roof is made of. Older flat roofs are frequently felt or asphalt, newer ones rubber or GRP.
We write the report in plain English, so you do not need to be a roofer to follow it. Each point is backed by a photo where possible.

What this survey cannot tell you
Our survey is not a RICS Level 2 or Level 3 survey, a structural engineer’s report or an asbestos survey. Other limits to bear in mind:
- Whether the deck or joists are strong enough
- Areas we can’t see or reach safely, including fragile rooflights and sheeting
- A fixed date for when the roof will need replacing
If you are not sure which survey you need, call 07833 053749 or send us an email and we will give you a straight answer before you book. The full list of what we check.
What we look at
- Felt flat roofs
- Single-ply membranes
- EPDM rubber
- Mastic asphalt

What a survey costs
Every roof is different, so prices are confirmed before booking. This is what makes a difference:
- Building height and the viewpoints available
- How big the roof is
- Whether thermal imaging or a drone is needed
- The number of roofs, including extensions and garages
Prices start from £150, inc. VAT, for a Basic Survey. Standard is from £250 and Premium from £400. You’ll know the price for the job before booking.
Helping us price your survey
There is no need for technical words. It is enough to tell us:
- Your postcode, so we can check access and travel
- What’s prompted the survey
- Any photos you have, taken from ground level or a window
- Access details, such as a loft hatch or a shared roof

How the survey works
Where it’s relevant and can be reached safely, the roof space is checked as well as the outside. In the loft, the signs we look for are staining, damp, daylight and sagging. The whole visit usually takes roughly 1–2 hours for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. For a visit in Mugswell, parking and access are the things to plan: let us know about permits, visitor bays or off-street space, which floor the property is on and how to get into the loft. We then look at everything that’s safely in view from ground level, windows, the loft and, where it’s safe, the roof itself.
- You tell us about the roof, its covering if you know it, and any leaks.
- We check the roof from wherever it can safely be seen.
- The covering, falls, upstands, outlets, edge trims and rooflights are checked and photographed.
- Inside, we look for damp and staining under the roof where there’s access.
- The findings are written up with photos and recommendations and emailed to you.
Getting ready for the survey
- Point out any leaks or damp patches
- Gather any invoices or paperwork from past roof work
- Keep pets out of the way during the survey

Related advice
Can I check my roof myself?
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. Don’t go up yourself.
The one thing to avoid is getting up close. Roofs are fragile and slippery, and a fall can be serious. That is where a survey comes in.
Flat and commercial roofs around Mugswell
In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. If your home in Mugswell is one of them, bay roofs, hips and later dormers each have their own details. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. England has around 10,000 conservation areas and about 500,000 listed buildings. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material, so check with the council.
If you look after a shop, office or commercial unit, for instance near The Belfry, the flat roofs over shops and commercial units are worth checking before a leak, not after. For a London address like Mugswell, it helps to know about controlled parking before the day, along with any off-street space. For site and facilities teams at buildings like Kingswood Primary School, a large flat roof with plenty of outlets and rooflights has many places where a membrane can fail.

Your questions about flat roof surveys in Mugswell
Will parking be an issue for a roof survey in Mugswell?
Typically it is manageable with a little notice. Tell us what parking is available nearby, and the visit is planned around it.
How do I find out if my home in Mugswell is listed?
For listing, use Historic England’s list; for conservation areas, ask the council. The answer matters most when a change of material is on the cards.
What will the report tell me?
It sets out what we found, why it matters and what we recommend, with photographs throughout. It also says if any part of the roof couldn’t be seen safely, so you know exactly what was covered.
Can you give me structural calculations?
No. We point out what can be seen, such as sagging or deflection, but we don’t carry out calculations or give an engineer’s opinion. If we think you need an engineer, the report says so.
Will you walk on the flat roof?
Where it’s safe, the roof is inspected from the roof itself. If not, we use safe viewpoints and look inside, and we note any area we couldn’t see. Fragile surfaces are never walked on.
Can you inspect my roof with a drone?
Where it helps and the rules allow, yes. We hold a CAA Flyer ID and Operator ID and fly a drone under 250g, and every flight depends on the airspace and the weather.
How soon will I get the report?
Basic reports arrive within 48 hours, Standard reports in 24–48 hours and Premium reports on the same day. All of them come by email.
