Flat roof survey in Blackwater: what you get
Water through a flat roof doesn’t always come in where the stain is. It can run along the deck from a split, an open lap or a failed upstand some distance away. Our survey covers the whole roof, not just the part above the mark, with photographs of anything that could be letting water in. Whoever carries out the work then has a clear starting point. We survey felt flat roofs, mastic asphalt and upstands and outlets, and the problems we’re asked to look at most are upstands pulling away from walls and blocked or damaged outlets.
Around a smaller place like Blackwater, flat roofs usually cover extensions, garages and dormers. They’re small, but a leak over a kitchen extension can do a lot of harm. What it is covered in, and how well it was laid, decides what it needs, from felt and asphalt to EPDM rubber and GRP. Ponding, splits and lifting edges are the signs to look for from a window.
What you get is a clear record of the flat roof on the day we saw it. It’s useful right away, and a good reference for later.

Local flat roofs in Blackwater
Some Hampshire villages still have thatched roofs. Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles. Next to the main roofs there’s normally a flat roof somewhere, whether on an extension, a garage or a commercial unit. An older home may be listed, or stand in a conservation area. Historic England’s list shows listed buildings, and the council can say whether a street is in a conservation area. Re-roofing in different materials may need permission there.
For landlords with property near Blackwater station, flat roofs on let property tend to be checked only when they fail, which is the costly way round. Take a building like Frogmore Infant School: schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.
Blackwater is about 1 mile south of Sandhurst, in Hampshire. We visit Blackwater as part of our work across Hampshire, for homes and businesses alike. Blackwater is one of the towns and villages in Hampshire we cover for flat roof surveys. For surveys nearby, see our Reading page.

Questions from Blackwater
Does a conservation area affect roof work in Blackwater?
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.
Do you cover Blackwater?
We do. The survey and report are the same in Blackwater as anywhere else.
How long will you be at the property?
That depends on the size and shape of the roof, but most surveys take about 1–2 hours for a small flat roof at home, and longer for a large commercial one. The report is sent afterwards by email.
Will you photograph what you find?
Yes, every report has them. Pictures sit next to the findings they show.
Do you cover flat roofs on blocks of flats?
Yes. Offices, units, shops and blocks of flats are all part of our work. Larger commercial roofs are quoted for their size and access, so please phone 07833 053749 or drop us an email with the details.
How do you inspect a flat roof?
Where it is safe, the roof is inspected from the roof itself. Otherwise we use windows, vantage points and the spaces below, and the report says if any part couldn’t be seen. Fragile surfaces are never walked on.
Can you survey at the weekend?
Visits run seven days a week in the daytime. Just say which days work for you.
What affects the price in Blackwater
Every roof is different, so prices are confirmed before booking. This is what makes a difference:
- The package you choose: Basic, Standard or Premium
- Extensions, dormers and garages with roofs of their own
- The height of the building and how the roof can safely be seen
- The shape of the roof and its details
The Premium Survey includes thermal imaging and drone inspection where it applies, which starts from £400, including VAT. We can help you choose the package that fits what you need to know.
Helping us price your survey
When you call or email, these details help:
- The style of property, from a terrace to a block
- Dates you’re working to, such as exchange
- Where water is showing inside, if it is
- Any photos you have, taken from the ground or a window
Not sure which survey you need? It’s easiest to phone 07833 053749 or send us an email and describe the roof and why you want it surveyed. We will talk you through the options and what they cost.
Common roof problems in Blackwater
The surface of a flat roof heats up and cools down far more than the rooms below. That movement pulls at seams, laps and the joints between boards, and in time it can open up splits and cracks. Coverings that have hardened with age tend to suffer most.
A survey can pick up problems such as:
- Leaks around rooflights
- Splits and cracks in the covering
- Dips that suggest the deck is deflecting
- Pools of water lying on the roof
Take an older house close to St Barnabas Church: the joins between later flat roofs and the old walls are where problems usually start.
Questions to ask before you book
- Whether the loft is part of the inspection
- How soon the report will arrive
- Whether you can ask questions once you have the report
- Whether the price includes VAT
Landlord and commercial surveys in Blackwater
We also survey roofs for businesses and commercial landlords, including offices, shops and units. Bigger roofs take more time, so they’re priced to suit.
We survey roofs for letting agents and landlords as well as homeowners. A written report with photos gives you a clear record of the flat roof, which helps you plan work between tenancies.
What a flat roof survey doesn’t cover
We only report everything that’s safely in view on the day, so there are some things a survey cannot cover:
- Parts of the roof that aren’t safe to walk on or view
- The condition of the deck or insulation hidden under the covering
- A structural engineer’s assessment of the deck
If you are not sure which survey you need, call 07833 053749 or use the contact form and we’ll give you a straight answer before booking. What a survey covers and does not.
Roof types and parts we check
- Upstands and outlets
- Mastic asphalt
- Felt flat roofs
- EPDM rubber
- GRP fibreglass
- Single-ply membranes
Roof by roof
GRP fibreglass
Movement in the deck or a thin layer of resin can lead to cracks in GRP. We record any cracking and any signs of the deck moving.
Mastic asphalt
Asphalt has no laps, so its weak points are cracks and the skirtings at walls and upstands. Our report notes crazing, cracks and any likely entry points.

What happens on the day
After the inspection, everything we found is written up as a report with photographs, sent to you by email. As for time on site, most surveys take roughly 1–2 hours for most houses; commercial roofs usually need 3–4 hours. In a smaller place like Blackwater, as anywhere, the forecast plays a part: the parts that need calm, dry weather are planned around it.
- You send us the address and, for commercial roofs, an idea of the roof’s size.
- We check the rooms or spaces under the roof for staining where there’s access.
- The roof is inspected from every safe viewpoint, without walking on fragile surfaces.
- Each defect is photographed and its likely cause noted.
- The report explains the condition and recommends what to do first.
Preparing for the visit
- Jot down any questions you want answered
- Keep pets in another room
- Move anything stored under the loft hatch
