What a flat roof survey looks like in Winchmore Hill
Outer London has plenty of Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, often with hipped roofs in clay or concrete tiles. If your home in Winchmore Hill 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. With Bruce Castle about 2.6 miles south-east, Winchmore Hill sits in an area with a long building history. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and a listed home or one in a conservation area may need consent for changes of material.
Landlords with a home close to Winchmore Hill station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round. Anyone responsible for a site like St. Paul's School will know that ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.

Flat roof surveys for homes and businesses in Winchmore Hill
Our flat roof survey checks the waterproof covering and every detail around it, from edges and upstands to outlets and rooflights. We cover felt, mastic asphalt, EPDM rubber, GRP fibreglass and single-ply roofs. We survey extension, garage and dormer roofs as well as bigger roofs on flats, offices and units. You get a report with photographs and our recommendations. We’re frequently asked to look into failed upstands where the roof meets a wall and dips that suggest the deck is deflecting, across GRP fibreglass, felt flat roofs and upstands and outlets.
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 Winchmore Hill shapes how it’s checked. Many older flat roofs are felt or asphalt, and many newer ones EPDM rubber or GRP.
If any part of the flat roof couldn’t be seen safely, we say so in the report. That way, it is clear what was covered and what wasn’t.

What we’re asked to look at in Winchmore Hill
Every flat roof covering has a working life. Around 15 to 20 years is common for felt, while EPDM frequently lasts 30 to 50 years and GRP up to about 30, although how well it was laid and looked after matters a great deal. We can tell you how your roof is doing, whatever its age.
People normally book a survey when they’ve noticed something like this:
- Edge trims that have lifted or split
- Blocked or damaged outlets
- Standing water left after rain
- Failed seals around rooflight kerbs
For a London address like Winchmore Hill, it helps to know about controlled parking before the day.
What to check before booking
- What happens after the report arrives
- Their track record with similar roofs
- Whether any drone flown is registered with the CAA
- Whether the inside of the roof is included
How it works
Every roof is different; as a rough guide, the survey takes an hour or two for most houses, though large, tall or awkward roofs take more time. You’re welcome to ask questions while we’re there. In converted houses and mansion blocks, the loft hatch is frequently on a shared landing. Where that is the case, access needs agreeing with whoever controls that landing. Otherwise, the visit in Winchmore Hill runs like any other.
- You tell us about the roof, its covering if you know it, and any leaks.
- We view the roof from ground level, 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.
- Where there is safe access, we look at the ceilings and spaces below for signs of water.
- We send a written report with photos, the defects we found and what we recommend.
Getting ready for the survey
- Tell us where we can park nearby
- Jot down any questions you want answered
- Move anything stored under the loft hatch

Winchmore Hill: your questions answered
Is my home in Winchmore Hill listed or in a conservation area?
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.
Do you carry out roof surveys in Winchmore Hill?
Yes, Winchmore Hill is within the area we cover. We work right across London and South East England. You can ring 07833 053749 or send us an email with the address and a few details, and we will talk through which survey suits.
Do you need to get into the loft?
Where it’s relevant to the survey and there’s safe access, yes. Please clear anything stored under the hatch, and if the loft can’t be reached safely, the report says so.
What does a roof survey cost?
Flat roof survey starts from £150, including VAT. The final figure depends on the roof and the package you choose, confirmed before anything is booked.
Will I get photos?
Yes. Photographs are taken throughout the survey, and they go into the written report.
What happens next?
You’ll get the report by email. The Standard Survey includes a follow-up consultation, and the Premium Survey an in-person consultation, so you can talk the findings through.
Can you test old roof sheets for asbestos?
We do not carry out asbestos surveys. Buildings built or refurbished before 2000 may contain asbestos, for example in cement roof sheets. We note anything that could contain it, and a specialist asbestos surveyor should check it before it’s disturbed.
For landlords and managing agents
For blocks of flats, a roof survey helps managing agents and residents’ management companies plan ahead. The report sets out what needs attention now and what can wait, which helps when budgeting.
Letting agents often book on a landlord’s behalf, and the report can go to both. We agree a time with the tenant beforehand.
Tips that help
Most of what helps is simple and safe from the ground. A few suggestions:
- Check ceilings under the roof for damp patches
- Book a survey every few years
- Check the outlets after the leaves fall
- File the paperwork for the roof and any repairs
If you’re buying, the report gives you something specific to take back to the seller or agent. You might ask for work to be done before completion, or discuss the price, depending on what we found.
Check the roof from a window after a downpour. Water still lying a day or two later is worth getting looked at.
Roof by roof
Single-ply membranes
Single-ply PVC and TPO membranes are common on commercial roofs and newer buildings. The survey looks at welded seams, edges, fixings and signs of damage.
EPDM rubber
EPDM frequently lasts 30 to 50 years, but it relies on its seams, trims and upstands being well finished. Those details are where we focus.
