About our flat roof survey in Oakleigh Park
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. Common reasons to book are splits, cracks and crazing and blocked or damaged outlets, on GRP fibreglass, upstands and outlets and felt flat roofs.
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 Oakleigh Park, 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.
The Standard Survey adds moisture detection, a structural check and a follow-up consultation. The Premium Survey goes further, with thermal imaging, drone inspection where it applies, structural analysis and an in-person consultation.

Different roofs, different checks
Rooflights and upstands
Rooflights, lanterns and upstands are where many flat roof leaks begin. We check the seals and the covering around each one.
Single-ply membranes
Many offices, units and newer flats have a single-ply PVC or TPO roof. We check the welded laps, the edges, the fixings and any punctures.
Flat roof surveys around Oakleigh Park
Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of clay or concrete tiles. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. Heath Hall, about 3.5 miles south, is one of the historic houses in the wider area around Oakleigh Park. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and any change of roofing material on a listed home needs checking with the council first.
Controlled parking zones are common in London, so mention any permit rules for Oakleigh Park, along with any off-street space. For landlords with property near Oakleigh Park station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.

Oakleigh Park questions
Will parking be an issue for a roof survey in Oakleigh Park?
Parking in Oakleigh Park, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly.
How do I find out if my home in Oakleigh Park is listed?
We can’t confirm that for you, but Historic England’s list and your council can. Both listing and conservation areas can limit changes of roofing material, and councils can also use Article 4 directions.
Can you survey a flat roof on an office or unit?
Yes. We survey flat roofs on commercial buildings as well as homes. A commercial roof usually takes about 3 to 4 hours on site, longer if it is large or complex, with larger roofs quoted on their size.
Are you insured?
Every survey is covered by professional indemnity and public liability insurance, and we can provide details if a managing agent needs them.
How much is a survey?
Flat roof survey starts from £150, including VAT. We confirm the price for your survey before booking. To get a price, phone 07833 053749 or drop us an email.
Do you survey roofs on blocks of flats?
Yes, as long as access is agreed. The roof of a block or converted house is often shared, so we need permission from the building owner or managing agent. We inspect only the parts we’re allowed to reach.
How long will you be at the property?
It typically takes about one to two hours for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. The report follows by email.
Landlords, agents and block managers in Oakleigh Park
Surveys can also be booked by buyers’ agents acting for a client. Reports are emailed, so they’re easy to pass on.
For a freeholder or residents’ company, a roof report is a sound basis for a maintenance plan.
How the survey works
The visit normally starts outside and finishes in the loft: outside views come first, then the loft space if there’s safe access. In total, it takes roughly 1–2 hours for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. Surveys in Oakleigh Park can be booked for any day of the week. London parking is frequently by permit or pay-and-display, so it helps to know what’s near you. Upstairs rooms at the back are useful too, as they often give the best view of a rear addition.
- First you give us the address, what the roof covers and any leaks you’ve noticed.
- The roof is inspected from safe viewpoints, and from the roof itself where that’s safe.
- 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.
- The findings are written up with photographs and recommendations and emailed to you.
Before the survey
- Find any records of previous roof work
- For a flat or shared roof, check access with the building owner or managing agent
- Let us know about parking near the property

Advice
Useful tips for Oakleigh Park property owners
A little preparation and a few simple habits help. Some pointers:
- Clear roof outlets and gutters each autumn
- Keep clear of rooflights and fragile roof sheets
- Check from a window for ponding after heavy rain
- Note any new marks on ceilings beneath the roof
You can use the report to ask roofers to quote for the same work. With each roofer working from the same list, comparing quotes is simpler. It is your choice who carries out the work and when.
Keep foot traffic on a flat roof to a minimum. Where someone does need access, ask them to use boards or a protected route, and to keep well clear of rooflights and fragile sheeting.
What affects the price in Oakleigh Park
Several things affect the price of a survey:
- The number of roofs, including extensions and garages
- Any need for thermal images or a drone flight
- How tall the building is and how easy the roof is to see
- The size of the roof
The Premium Survey includes thermal imaging and drone inspection where it applies, which starts from £400, inc. VAT. We will tell you which package suits the questions you have.
Helping us price your survey
You do not need to know any roofing terms. It is enough to let us know:
- Photos of the roof, taken safely from ground level or a window
- Where the property is, with the postcode
- The kind of building and roof involved
- Your timetable, such as an exchange date
Flat roof survey starts from £150, including VAT. What you pay depends on the roof’s size, access and the package, and you can ring 07833 053749 or use the contact form to find out.
Signs you need a flat roof survey in Oakleigh Park
A flat roof lies open to sun, rain and frost, and water drains off it slowly. In time, the covering dries out, cracks and loosens at its edges and laps. Most people book a survey after a leak, before buying, or when they think the roof is getting old.
These are some of the problems a survey can pick up:
- Edge trims that have lifted or split
- Dips that suggest the deck is deflecting
- Pools of water lying on the roof
- Failed seals around rooflight kerbs
If you run a business near Grand Arcade, the flat roofs over shops and commercial units are worth checking before a leak, not after.
Before you book anyone
- When you’ll get the report
- Are they insured for the work?
- Whether the loft is part of the inspection
- Their track record with similar roofs
