About our flat roof survey in Addlestone
Offices, shops, industrial units and blocks of flats often sit under large flat roofs. A survey of a roof this size picks out worn covering, standing water and outlets that need attention. We record the condition with photographs so work can be planned and budgeted. Commercial roofs are quoted for their size and access, so please ring 07833 053749 or drop us an email with the address and an idea of the roof’s size. We’re frequently asked to look into blisters and bubbles in the covering and water getting in at rooflights, on felt flat roofs, GRP fibreglass and EPDM rubber.
Around Addlestone, many homes have a garden room, garage or outbuilding with a flat roof. They’re easy to forget, but water through a garage roof can spoil whatever is stored inside. It’s worth mentioning them as you book, so the visit can include them. Felt, rubber and GRP coverings on garages and outbuildings age in just the same way as the main roof’s.
Most points in the report come with a picture, so you can see each defect rather than just read about it. Anything out of sight on the day is listed as such.

Why act early in Addlestone
By the time a flat roof leak shows indoors, water has already passed through the roof build-up. A survey can find worn areas and failing details before that point, so you can plan the work rather than react to it. On a bungalow or cottage around Addlestone, the roof sits close to the rooms below, so water can show inside quickly once it gets past the covering. Finding the cause first saves a second job inside.
Every price we give includes VAT, and the report isn’t charged as an extra. Flat roof survey starts from £150, including VAT. Size, height and access decide where your roof falls.

This is not a RICS building survey, a structural engineer’s report or an asbestos survey. Other limits to bear in mind:
- An exact number of years the roof has left
- Testing older roof sheets for asbestos

Addlestone questions
Is my home in Addlestone listed or in a conservation area?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you are planning to re-roof in a different material.
Is Addlestone in the area you cover?
Yes. Our area covers London and the South East, and Addlestone is part of that. Just call 07833 053749 or drop us an email and let us know about the property, and we will talk through which survey suits.
Can you give me structural calculations?
No. Visible signs like deflection or sagging are recorded, but calculations and an engineer’s opinion are outside what we do. If one is needed, the report says so.
Are you insured?
Professional indemnity and public liability insurance cover our surveys. Ask if you need details for a managing agent or building owner.
Will the survey show why my flat roof is leaking?
Our survey looks across the whole roof, not only above the stain. Splits, open laps, upstands, outlets and rooflights are all checked. If the cause can’t be seen, we’ll say so and suggest what would help.
Which flat roof coverings do you cover?
Felt, asphalt, EPDM, GRP and single-ply roofs are all covered. Not sure what yours is? We will tell you in the report.
Can you survey a shared roof?
Yes. Shared roofs just need a little more planning, with whoever owns or manages the building. Mention it when you get in touch and we will plan the survey around it.
What a survey costs
To price your survey, we check:
- Whether you choose the Basic, Standard or Premium Survey
- The shape of the roof and its details
- How tall the building is and how easy the roof is to see
- Roof area
Price depends partly on the package: from £150 for Basic, £250 for Standard and £400 for Premium, inc. VAT. The roof’s size, height and access matter as well.
What to let us know when you get in touch
Getting the details right at the start saves time. Please include:
- The kind of building and roof involved
- How the loft is reached, if there is one
- Any photos you have, taken from the ground or a window
- The property’s address and postcode
Prices start from £150, including VAT. The exact figure depends on the roof and the package, so phone 07833 053749 or drop us an email with the details.
How the survey changes by roof type
Single-ply membranes
Single-ply relies on its welded laps staying sound. Seams, corners and the details around outlets and upstands get a careful look.
Rooflights and upstands
Where a flat roof meets a wall, the upstand has to stay sealed as the building moves. We look for splits, gaps and failed flashings over the top.

How it works
The aim of the visit is simple: to look at the flat roof as closely as is safe and record what we find. Notes and photos go into the written report. The visit usually takes roughly 1–2 hours at a typical home, rising to roughly 3–4 hours on a commercial building. Being in a smaller place like Addlestone doesn’t change how the visit works: outside, inside and from any safe vantage point, in that order. Point out any stains, cracks or loose pieces you’ve spotted.
- 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.
- Each defect is photographed and its likely cause noted.
- You get a report setting out the condition and our recommendations, in order of urgency.
Before we arrive
- Point out any leaks or damp patches
- If you’re buying, check with the agent that we can get in
