Your questions about flat roof surveys in Alverstoke
Is Alverstoke within the area you cover?
Yes. Alverstoke is within the area we cover, which takes in towns, villages and rural addresses. We cover the whole of London and South East England. Let us know about access, parking and anything unusual about getting there when booking.
Does a conservation area affect roof work in Alverstoke?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. It matters most if you are planning to re-roof in a different material.
What happens next?
The report comes by email, and what you do next is up to you: use it with a seller, an insurer, a roofer or a managing agent.
Can you find where water is getting through my flat roof?
We check the whole roof, since water can travel before it shows inside. Splits, open laps, upstands, outlets and rooflights are all checked. If the cause cannot be seen, we will say so and suggest what would help.
Is a flat roof survey the same as a building survey?
No. It is a closer look at the flat roof, not a survey of the whole property. It works alongside a RICS home survey, not instead of one, and structural calculations need a structural engineer.
How much does a flat roof survey cost in Alverstoke?
Prices start from £150, including VAT. Our three packages are Basic from £150, Standard from £250 and Premium from £400, inc. VAT.
Can you test old roof sheets for asbestos?
We do not test for asbestos. If we see materials that could contain it, such as cement sheets on a building from before 2000, we flag them so a specialist asbestos surveyor can check them.
About our flat roof survey in Alverstoke
Flat roofs deal with rain in a very different way from pitched ones. Because rain sits on it for longer, a small split, an open seam or a blocked outlet matters more. We check the surface, the falls, the upstands and the edge trims, and we note any sign that the deck below has got wet. The aim is to find problems before they show up as a stain on a ceiling. We survey GRP fibreglass, upstands and outlets and mastic asphalt, and common reasons people get in touch are loose or cracked edge trims and a sagging deck under the covering.
Somewhere as small as Alverstoke, flat roofs tend to be on extensions, garages and converted outbuildings. The checks are the same as anywhere: outlets, upstands, edges and the covering itself. We simply plan the journey and access ahead of time. If there are outbuildings or garages with flat roofs, mention them as you book.
Most points in the report come with a picture, because a photo of a cracked flashing says more than a paragraph. If something couldn’t be seen safely, the report is clear about it.

What you can safely check yourself
A lot can be seen from ground level. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Never climb onto the roof to look.
Fresh stains on ceilings or walls after rain are worth noting. Photograph them and note the date.
What this survey can’t tell you
It’s useful to know what a survey won’t do before booking:
- A promise that the roof will not leak in future
- Whether old sheeting or boards contain asbestos
- Areas we can’t see or reach safely, including fragile rooflights and sheeting
If in doubt, call 07833 053749 or use the contact form and we’ll recommend the right survey before you book. What our survey covers.
What we check
- Felt flat roofs
- EPDM rubber
- Mastic asphalt
- Upstands and outlets
- Single-ply membranes
- GRP fibreglass
What we do, step by step
There is not much for you to do on the day. Show us any stains, drips or problem areas you know about, and we will get on with the inspection. The survey itself takes roughly 1–2 hours for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. Around Alverstoke, older homes can have small or awkward roof spaces, so let us know about the loft hatch and any ladder. We only go where it is safe.
- 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.
- We view the roof from safe positions and never walk 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.
How to prepare
- If you are buying, check with the agent that we can get in
- Let us know about parking before the day
- Point out any leaks or damp patches
How to book
We survey roofs seven days a week. To arrange a day that suits you, ring 07833 053749 or drop us an email with the address and the days you’d prefer.

Tips that help
From years of surveys, a few habits stand out as worth the effort:
- Keep outlets clear of leaves and moss
- Note where water lies after a downpour
- Limit foot traffic on the covering
- Note any new marks on ceilings beneath the roof
You can use the report to ask roofers to quote for the same work. With each roofer working from the same list, comparing quotes is simpler. You stay in control of who does the work and when.
Try not to let a flat roof become a walkway. If access is needed, boards or walkways help protect the covering, and remind them never to step on rooflights or fragile sheets.
When to book a survey in Alverstoke
A buyer’s general survey often recommends a closer look at a flat roof. Building owners and managing agents book to plan maintenance, or before a sale or a new lease. In each case, the report gives a written, photographed record of the roof’s condition.
It is worth booking a survey if you’ve seen:
- Gaps at upstands and abutments
- Water getting in at rooflights
- Damaged trims at the roof edge
- Outlets that hold water back
Anyone responsible for a site like Alverstoke Community Infant School will know that a large flat roof with plenty of outlets and rooflights has many places where a membrane can fail.
Before booking anyone
- Is VAT included in the price?
- Which limits apply to the survey
- What the report includes, and whether it has photos
- Is there a chance to talk the report through?
Why get it checked now?
Flat roofs can’t normally be seen from the street, so they’re often overlooked. Owners often learn the roof is at the end of its life only when it leaks. A survey every few years stops that from catching you out. Around Alverstoke, older homes frequently have old roof timbers, and water through a failed covering can rot timber if it is left.
Flat roof survey starts from £150, including VAT. What you pay depends on the size and height of the roof, how it can be seen safely and the package you choose.

What a flat roof survey looks like in Alverstoke
Alverstoke is within about 1 mile of the coast, so there is more wind and more salt in the air than further inland. Salt in the air is hard on metal flashings and fixings, and wind catches any loose edge on a flat roof. Before planning roof work on an older home, find out whether it’s listed or in a conservation area. Listed building consent covers changes to a listed building’s special interest, and an Article 4 direction can bring extra controls in a conservation area.
If you run a business near Tricorn Centre, a flat roof over a business is out of sight and out of mind until it leaks. Landlords with a home close to Portsmouth Harbour station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round.
