Common roof problems in Twickenham
A flat roof lies open to sun, rain and frost, and water drains off it slowly. Over the years, coverings harden, crack and start to come away at the edges. People typically call us when a leak appears, before a purchase, or when the roof may be near the end of its life.
A survey can pick up problems such as:
- Failed upstands where the roof meets a wall
- Splits, cracks and crazing
- Pools of water lying on the roof
- Loose or cracked edge trims
Shop and office owners around Treaty Centre may find that outlets and upstands on commercial flat roofs are the places to check before trouble starts.
Questions to ask before you book

- What insurance they carry

Flat roof surveys for homes and businesses in Twickenham
A Basic Survey, from £150, covers a visual inspection, a condition report, photos and written recommendations. The Standard Survey, from £250, adds moisture detection and a structural check. Moisture readings are useful on flat roofs, where water can spread under the covering before it shows inside. Larger commercial roofs are quoted for their size. We survey single-ply membranes, GRP fibreglass and mastic asphalt, and the problems we’re asked to look at most are gaps at upstands and abutments and a sagging deck under the covering.
Commercial and residential blocks across London often have big flat roofs with plant, rooflights and access walkways. Each pipe, upstand and fixing through the covering is a possible weak point. In Twickenham, roof access is agreed with the building manager or owner beforehand. Plant bases, rooflights and cable entries are all places where water can get in.
Nothing in the report is left vague: where something needs attention, it says so plainly, along with how urgent it is.

How it works
On the day, we start by asking what you’ve noticed and what you need to know. After that, we look at everything we can see safely, using the ground, windows, the loft and a drone where it applies. Most surveys take an hour or two for most houses, and longer for a large or complex roof. Surveys in Twickenham can be booked for any day of the week. It helps if you can point us to a visitor permit or a nearby bay, and to clear a path to the loft hatch. Upstairs rooms at the back are useful too, as they frequently give the best view of a rear addition.
- We agree the roof to be surveyed, its use and any leaks you know about.
- We look at the roof from the ground, windows and the roof where it is safe.
- The covering is checked for wear, splits, blisters and standing water.
- We photograph and record the outlets, upstands, trims and rooflights.
- A written report with photos and recommendations is emailed to you.
Before the survey
- Let us know where we can park nearby
- Buyers: confirm access with the estate agent or seller
- Have any questions written down, so nothing gets missed

Advice
Tips from our surveys
These tips come from what we see on roofs every week:
- Note the date and type of any roof work
- Note where water lies after a downpour
- Check the outlets after the leaves fall
- Ask whoever fits equipment on the roof to make good the covering
If anything in the report is not clear, just ask us. The Standard Survey includes a follow-up consultation and the Premium Survey an in-person consultation, giving you a chance to go through what we found.
Book a survey every few years, and again after new fixings, units or rooflights go in. You’ll spot changes early and have a record to look back on.
When you need someone else
Every survey has limits, and it is better to know them up front. Bear these in mind:
- Hidden layers beneath the covering
- Parts of the roof that are not safe to walk on or view
- A structural engineer’s assessment of the deck
Not sure which survey suits your roof? You can ring 07833 053749 or drop us an email and we’ll tell you before you book. What our survey covers.

Flat roofs in Twickenham
About 0.5 miles east lies Richmond House, a reminder of how long the area around Twickenham has been built on. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, 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. If your home in Twickenham is one of them, bay roofs, hips and later dormers each have their own details. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
Take a building like St Richard Reynolds Catholic Primary School: a large flat roof with lots of outlets and rooflights has many places where a membrane can fail. If you let a flat or house near Twickenham station, the flat roof over a let home is worth a look before it becomes a tenant complaint.

Why get it checked now?
A survey can show whether a whole new roof is needed or whether the problems are in a few places. Sometimes some details are to blame, and sometimes the covering has simply had its day. Our report gives you the evidence to discuss with a roofer. Work on a London roof is rarely simple to arrange, with parking, neighbours and access all to think about. That is a good reason to find problems early, while there’s time to plan, rather than in a rush after a leak.
Prices start from £150, including VAT. What you pay depends on the size and height of the roof, access and the package you choose.

Different roofs, different checks
EPDM rubber
EPDM often lasts 30 to 50 years, but it relies on its seams, trims and upstands being well finished. Those details are where we focus.
GRP fibreglass
Movement in the deck or a thin layer of resin can lead to cracks in GRP. Our report notes cracks and any sign that the deck is flexing.
FAQs for Twickenham
Will parking be an issue for a roof survey in Twickenham?
It can be, so it helps to tell us about permits, visitor bays or off-street space when booking. That way the visit can be planned around it.
Is my home in Twickenham listed or in a conservation area?
Your council is the best source, with Historic England’s list for listed buildings. A change of roofing material may need consent in either case.
What happens after the survey?
You will get the report by email. The Standard Survey includes a follow-up consultation, and the Premium Survey an in-person consultation.
Will I get photos?
Yes. Photographs are part of every report, so you can see each point for yourself.
Do you check flat roofs for asbestos?
Asbestos testing is not part of our survey. If we see materials that could contain it, like cement sheets on a building from before 2000, we flag them so a specialist asbestos surveyor can check them.
Should I worry about standing water on my flat roof?
Ponding is worth looking into. It can point to blocked outlets, poor falls or a deck that is sagging, and water that sits wears the covering sooner. Our survey notes the ponding and what seems to be causing it.
Do I need to be at home?
Not necessarily. If we only need the outside, we can agree that beforehand, but the loft and any rooms with damp need someone to let us in.
