Flat Roof Survey in Westhumble
Not sure what state the flat roof is in? We carry out flat roof surveys in Westhumble and across Surrey, with plain-English findings.
- Leaks around rooflights
- Blistering in felt or asphalt
- Edge trims that have lifted or split
When you need someone else
Our findings are based on what we can see safely on the day, so there are some things a survey can’t cover:
- A promise that the roof will not leak in future
- Asbestos testing, which needs a specialist asbestos surveyor
- Hidden layers beneath the covering
If you’re not sure which survey you need, call 07833 053749 or send us an email and we’ll give you a straight answer before booking. The full list of what we check.
What we look at

Flat roof surveys for homes and businesses in Westhumble
If the house you are buying has a flat roof on an extension, dormer or garage, it is worth knowing its condition before exchange. Many felt roofs need renewing after around 15 to 20 years, and EPDM and GRP often go on for longer. Our report records the covering, how it’s holding up and any defects we can see, with a photo of every defect. That gives you facts to raise with the seller or agent. We survey felt flat roofs, upstands and outlets and single-ply membranes, and people most frequently book us about pools of water lying on the roof and water getting in at rooflights.
Flat roofs on exposed homes in small places like Westhumble take more wind and rain, which is hard on edges, upstands and joins in the covering. Older felt roofs, often around 15–20 years in life, show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. On an exposed roof, the edges tend to go first.
It isn’t only a list of defects. For each finding, it explains what it is, why it matters and what we’d recommend.

How the survey changes by roof type
Mastic asphalt
Without seams, asphalt tends to fail through cracking and at its skirtings. We record any crazing or splits and where water may be getting in.
GRP fibreglass
GRP can crack if the deck beneath flexes or if the resin was laid too thin. Our report notes cracks and any sign that the deck is flexing.
Landlords, agents and block managers in Westhumble
Letting agents and landlords in Westhumble book surveys as well as householders. The report gives you a dated record of the flat roof, with photos, which helps you plan work between tenancies.
If you own several properties, surveys can be booked for more than one address. To discuss a number of properties, ring 07833 053749 or drop us an email.
What we do, step by step
The visit normally starts outside and finishes in the loft: first the slopes, edges and gutters from every safe viewpoint, then the loft space where it can be reached. In total, it takes about 1–2 hours at a typical home, while a commercial roof takes nearer three to four hours. Rural addresses near Westhumble can be hard to find from a postcode alone, so a few directions, or a note of a nearby landmark, help us arrive on time. After that, the survey runs as it would anywhere.
- We start with the address and, on larger roofs, the roof area and access.
- Inside, we look for signs of water under the roof where we can reach.
- The roof is inspected from every safe viewpoint, without walking on fragile surfaces.
- We record every defect with a photo and its likely cause.
- The report explains the condition and recommends what to do first.
Getting ready for the survey
- Have keys ready for side gates, garages or roof access doors
- Leave a clear route to the loft
- If it is not your property yet, arrange access through the agent

What affects the cost of flat roof surveys

Tips from our surveys
Small things make a difference, both for the survey and for the roof itself. Some pointers:
- Ask whoever fits equipment on the roof to make good the covering
- Clear roof outlets and gutters each autumn
- Watch the ceilings below the flat roof for stains
- Treat rooflights and old sheeting as fragile
After the visit, we write up the report with photographs of what we found. It explains the covering, its condition and every defect, and what we recommend. Turnaround is within 48 hours for a Basic Survey, 24 to 48 hours for a Standard Survey and the same day for a Premium Survey.
Clear leaves and silt from outlets and gutters, above all in autumn. Water that can drain away does far less harm than water that sits.
