Keyhaven Flat Roof Survey
Surveys of flat roofs on homes, extensions and commercial buildings across Keyhaven, with drones and thermal imaging where they help. Call or email for a price.
- Failed seals around rooflight kerbs
- Upstands pulling away from walls
- Dips that suggest the deck is deflecting
Tips that help
You do not need to be a roofer to help. Here’s what helps most:
- Never stand on rooflights or fragile sheeting
- Note the date and type of any roof work
- Keep outlets clear of leaves and moss
- Ask whoever fits equipment on the roof to make good the covering
Landlords, owners and managing agents can keep the report as a dated record of the roof. It is useful when planning upkeep and setting budgets, and it gives a baseline to compare against next time.
Small defects are simpler to deal with while they’re still small. Prompt repairs tend to add years to a flat roof.
Flat roof surveys for homes and businesses in Keyhaven
Each type of flat roof has its own weak points. Built-up felt tends to blister and crack, asphalt crazes and splits, EPDM can lift at its laps, and GRP can crack at board joints and edge trims. Single-ply PVC and TPO roofs are checked at their welds, edges and fixings. Knowing what you have and how it’s doing helps you plan what comes next. Common reasons to book are failed upstands where the roof meets a wall and water getting in at rooflights, on mastic asphalt, EPDM rubber and felt flat roofs.
Flat roofs on exposed homes in small places like Keyhaven 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.
Report times depend on the survey you book: the Basic Survey within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey on the same day.

What we do, step by step
We’ll ask a few questions first, like when any problem began and what work has been done before. Then the inspection itself takes an hour or two for a house, and about three to four hours for a commercial roof. Rural addresses near Keyhaven can be hard to find from a postcode alone, so a few directions are welcome. The visit itself is the same as anywhere else.
- 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.
How to prepare
- Check pets are kept safely away
- Gather any invoices or paperwork from past roof work
- Have any questions written down, so nothing gets missed
How to book
A quick phone call is typically the easiest start: phone 07833 053749 or send us an email. The price is agreed before a date is set.
Related advice
Keyhaven: your questions answered
Does a conservation area affect roof work in Keyhaven?
Your council is the best source, with Historic England’s list for listed buildings. Both listing and conservation areas can limit changes of roofing material, and councils can also use Article 4 directions.
Is the coastal weather around Keyhaven hard on roofs?
Places near the sea get more wind and more salt in the air than inland, and both are hard on roofs. Salt is hard on nails, clips and metal flashings, while strong wind lifts anything already loose.
What does ponding on a flat roof mean?
Water that lies on a flat roof for days is a sign that something needs attention. The cause may be the outlets, the falls or the deck. The survey looks at each and records the likely cause.
Do you work in Keyhaven?
Yes. Our area covers London and South East England, Keyhaven included.
How long is the visit?
Time on site depends on the roof, but most surveys take about one to two hours for a small flat roof at home, and longer for a large commercial one. The report is sent afterwards by email.
Do you survey roofs on blocks of flats?
Yes, as long as access is agreed. The roof of a block or converted house is often shared, so whoever owns or manages the building needs to agree access. We can only inspect what we’re given access to.
Is it a structural engineer’s report?
No. We are roof surveyors, not structural engineers. If we see signs that need an engineer’s opinion, we’ll recommend one.
Checking the roof from ground level
Watch the gutters in a downpour, from a window or the ground. Water spilling over the edge can point to a blockage or a sagging run.
Look up at the roof after a storm, from ground level: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Leave anything above ground level to a survey.
How the survey changes by roof type
Rooflights and upstands
Where a flat roof meets a wall, the upstand has to stay sealed as the building moves. We check for splits, gaps and loose flashings above the upstand.
Single-ply membranes
Plant, fixings and foot traffic can all damage a single-ply roof. Any tears, punctures or loose membrane are recorded with photos.
Flat and commercial roofs around Keyhaven
Keyhaven is within about 1 mile of the coast, so there is more wind and more salt in the air than further inland. Coastal wind works at the edges of flat roofs, and salt air wears metal trims and fixings. A number of Hampshire villages keep thatched roofs on their older buildings. Older houses in the South East frequently 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.
Landlords with a home close to Lymington Town station may find that a flat roof over a rented flat is easy to forget until the tenant reports a leak. Take an older house close to Church of All Saints: flat-roofed rear additions and dormers added over the years are worth checking. For site and facilities teams at buildings like Milford-on-Sea Church of England Primary School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

How we price flat roof surveys
Not every roof costs the same to survey, for these reasons:
- Height and safe access
- How many separate roofs there are, such as extensions, dormers and garages
- The shape of the roof and its details
- Commercial roofs and larger buildings
Every price we give includes VAT, and the written report is part of the package. Our price is from £150, including VAT. Size, height and access decide where your roof falls.
Helping us price your survey
You do not need to know any roofing terms. Just let us know:
- Where the property is, with the postcode
- Where any leaks, stains or damp patches show inside
- The kind of building and roof involved
- Pictures of the roof from a safe spot, if you have them
Not sure which survey you need? The easiest way is to call 07833 053749 or use the contact form and describe the roof and what’s worrying you. We’ll talk you through the options and what they cost.
What we cannot see
A survey is a proper look at the flat roof, but it cannot do everything. Its limits include:
- Areas we cannot see or reach safely, including fragile rooflights and sheeting
- Whether the deck or joists are strong enough
- An exact number of years the roof has left
If in doubt, ring 07833 053749 or drop us an email and we’ll recommend the right survey. What our survey covers.
