Flat Roof Survey in Petersham
Not sure what state the flat roof is in? You can book a flat roof survey in Petersham and across Greater London.
- Blocked or damaged outlets
- Pools of water lying on the roof
- Gaps at upstands and abutments
Useful tips for Petersham property owners
These tips come from what we see on roofs every week, before and after a survey:
- Watch the ceilings below the flat roof for stains
- Look for standing water a day after rain
- Treat rooflights and old sheeting as fragile
- Have the roof looked at again after a severe storm
Once we’ve been, the findings are written up with photos. It covers the type of covering, its condition and each defect, with our recommendations. Basic reports arrive within 48 hours, Standard reports in 24 to 48 hours and Premium reports the same day.
Check the roof from a window after a downpour. Water still lying a day or two later is worth getting looked at.
Flat roof survey in Petersham: what you get
Ponding is often the first sign that something on a flat roof is not right. It can mean the falls were never right, an outlet is blocked or the deck has started to sag. We record where water sits, check the outlets and look for dips that suggest deflection. Where the deck may be a structural issue, our report says a structural engineer should look at it. We’re often asked to look into failed upstands where the roof meets a wall and standing water left after rain, on GRP fibreglass, felt flat roofs and single-ply membranes.
London has a lot of flat roofs: rear additions, dormers, roof terraces and the roofs of blocks and offices. Coverings range from felt and asphalt to EPDM rubber, GRP fibreglass and single-ply membranes, each with its own weak points. Which one is on a roof in Petersham shapes how it’s checked. Many older flat roofs are felt or asphalt, and many newer ones EPDM rubber or GRP.
Every survey ends with a written report, with photos, emailed to you. It sets out the condition of the flat roof, any defects and our written recommendations.

What we cannot see
We only report everything that’s safely in view on the day, so some things are outside what a survey can do:
- Areas we can’t see or reach safely, including fragile rooflights and sheeting
- A promise that the roof won’t leak in future
- A structural engineer’s assessment of the deck

How the survey works
It’s useful to start with what’s prompted the survey: buying, a leak, storm damage, new work or just wanting to know where things stand. That way we can focus on what matters to you. The visit normally takes about one to two hours for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. In Petersham, visits are available on weekdays and at weekends. It helps if you can point us to a visitor permit or a nearby bay. A back bedroom window can be the best vantage point for a rear addition, so we may ask to use one.
- You tell us about the roof, its covering if you know it, and any leaks.
- We view the roof from the ground, from windows and from the roof where it’s safe to do so.
- We check and photograph the covering, the falls, the upstands, the outlets, the trims and any rooflights.
- We check the rooms or spaces under the roof for staining where we can reach them.
- You get a written report with photos and our recommendations.
Before we arrive
- Let us know about parking near the property
- For flats, check roof access has been agreed
- Unlock side gates and any roof access doors

Advice
Flat roofs in Petersham
Further from the centre, London’s housing takes in interwar semis with hipped roofs in clay or concrete tiles as well as slate-roofed terraces. If your home in Petersham 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. About 0.5 miles south-east lies Pembroke Lodge, a reminder of how long the area around Petersham has been built on. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead.
Landlords with a home close to St Margarets (London) station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round. For hotels and guest houses around Petersham, a roof problem found early is far less disruptive than one found by a guest, so it is worth knowing the roof’s condition.

Do you need a flat roof survey in Petersham?
Many flat roof problems start at the details rather than the main surface. Upstands, trims, outlets and rooflight kerbs each move and weather in their own way. If they were rushed when the roof was laid, they’re frequently the first things to fail.
People usually book a survey after spotting something like this:
- A sagging deck under the covering
- Outlets that hold water back
- Ponding water that doesn’t drain away
- Gaps at upstands and abutments
Take an older house close to St Peter's Church: any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.

Leave it or get it looked at?
Standing water on a flat roof rarely sorts itself out. Most often it means blocked outlets, poor falls or a deck that is dipping, and each wet season wears the covering further. Knowing the cause early gives you more choice over what to do. A hidden valley or parapet gutter on a London house can hold water for weeks before anyone notices. By the time a ceiling stains, the timbers underneath may have been wet for a while.
Our price is from £150, including VAT. What you pay depends on how big and how high the roof is, access and the package you choose.
What you get with us

Your questions about flat roof surveys in Petersham
How do I find out if my home in Petersham is listed?
Start with Historic England’s list for listing and your council for conservation areas. It’s worth checking before planning roof work, as both can affect what’s allowed.
Can you look at the flat roof of a hotel or office near Petersham?
Yes, we cover commercial roofs as well as homes. Roof access is agreed with the building manager or owner beforehand.
How long have you been surveying roofs?
We’ve completed more than 5,000 surveys, over more than 20 years, and 98% of clients are satisfied.
Is this an asbestos survey?
No. Our report may flag materials that could contain asbestos, but confirming it is a job for a specialist asbestos surveyor. Buildings built or refurbished before 2000 may contain it.
Do I have to be there for the survey?
Not always. 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.
How much is a survey?
Prices start from £150, including VAT. We confirm the price for your roof before you book. For a price, ring 07833 053749 or send us an email.
What will the report tell me?
A photo-illustrated written report, explaining the condition of the flat roof, any defects and our recommendations. Standard adds moisture detection and a structural check; Premium adds thermal imaging, drone inspection where it applies and structural analysis.
