About our flat roof survey in Cold Harbour
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 photo-illustrated written report and our recommendations. Typical surveys look at raised blisters across the surface and splits, cracks and crazing, on felt flat roofs, EPDM rubber and single-ply membranes.
In a small place like Cold Harbour, a flat roof can stand in the open, so edges, upstands and laps take a beating. Felt roofs, which often last around 15–20 years, normally show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. Exposed edges are normally the first part of a flat roof to go.
It isn’t only a list of defects. It explains what we found, why it matters and what we recommend, so you can plan your next steps.

Flat roof surveys in Cold Harbour: local notes
Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. The wider area around Cold Harbour has a long history of building, with Harleyford Manor about 3.3 miles north. Older homes in the wider area frequently have features worth a closer look, like 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.
Take an older house close to Saint Peter: the joins between later flat roofs and the old walls are where problems usually start. For site and facilities teams at buildings like Knowl Hill Church of England Primary Academy, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.

What we look for on each type of roof
Mastic asphalt
Older asphalt can become brittle and crack as the roof moves. We note where this is happening and how widespread it looks.
Rooflights and upstands
Rooflights, lanterns and upstands are where many flat roof leaks begin. We check the seals and the covering around each one.
Surveys for landlords and agents in Cold Harbour
For a freeholder or residents’ company, a roof report is a sound basis for a maintenance plan.
Businesses and commercial landlords can book us too, including offices, shops and units. Bigger roofs take more time.
Why get it checked now?
A small split in a flat roof is typically a modest job when it is found early. Leave it, and water can get into the insulation and deck, which can turn a patch into a replacement. Surveying it now tells you where you stand. For an older or listed building in a place like Cold Harbour, repairs may need matching materials and consent, so a defect found early gives time to plan the work properly.
The Premium Survey includes thermal imaging and drone inspection where it applies, which starts from £400, inc. VAT. We can help you choose the package that fits what you need to know.

What happens on the day
We work from the outside in: outside views come first, then the roof space if there is safe access. All told, expect between one and two hours for a small flat roof at home, and longer for a large commercial one. Cottages and farmhouses around Cold Harbour frequently have roofs at several levels, with lean-tos and outbuildings attached. We work round each section in turn, from the safest viewpoints.
- First we go through the roof, what’s beneath it and any problems so far.
- The roof is viewed from safe positions, including the roof itself where that 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.
Getting ready for the survey
- Leave side gates unlocked
- Jot down any questions you want answered
- Gather any invoices or paperwork from past roof work
Getting a price
Prices start from £150, including VAT. The exact figure depends on the roof and the package, so ring 07833 053749 or use the contact form with the details.

What else we do in Cold Harbour
Do you need a flat roof survey in Cold Harbour?
Every flat roof covering has a working life. Around 15 to 20 years is common for felt, while EPDM often lasts 30 to 50 years and GRP up to about 30, although how well it was laid and looked after matters a great deal. A survey shows how yours is holding up, whatever its age.
Common reasons to book include:
- Blistering in felt or asphalt
- Water getting in at rooflights
- A sagging deck under the covering
- Loose or cracked edge trims
Landlords with a home close to Wargrave station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round.
Before booking any roof surveyor
- Whether they hold professional indemnity and public liability insurance
- Their drone registration, if they fly one
- Is there a chance to talk the report through?
- Which parts of the roof they’ll actually see
Tips that help
Here are a few things we’d tell any owner, before and after a survey:
- Clear roof outlets and gutters each autumn
- Check new fixings through the roof are properly sealed
- Note the date and type of any roof work
- Limit foot traffic on the covering
The report is emailed to you, ready to share with a roofer, the seller or a managing agent. It’s written in plain English, with a photograph of each defect, so anyone reading it can see what we saw.
Keep outlets, gutters and hoppers clear, especially after the leaves fall. A flat roof that drains well wears much more slowly.
FAQs for Cold Harbour
Does a conservation area affect roof work in Cold Harbour?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. It matters most if you’re planning to re-roof in a different material.

How many years has my flat roof got left?
There’s no honest way to give an exact number of years. Typical ranges are around 15 to 20 years for felt, 30 to 50 for EPDM and up to about 30 for GRP, but the report tells you how your roof is really doing.

It sets out what we found, why it matters and what we recommend, backed by photos. Anything we couldn’t see safely is noted too, so you know exactly what was covered.
