Flat roof survey in Dollis Hill
Water through a flat roof does not 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 photos of anything that could be letting water in. A roofer can then start from a clear picture of the problem. If you’ve noticed signs of deflection in the roof deck and upstands pulling away from walls, a survey will tell you what’s going on, whatever the roof.
Offices, shops and blocks of flats across London often have large flat roofs with plant, rooflights and walkways. Each pipe, upstand and fixing through the covering is a possible weak point. For a building in Dollis Hill, access is agreed with whoever manages the roof ahead of the visit. Plant bases, rooflights and cable entries are all places where water can get in.
What you get is a clear record of the flat roof on the day we saw it. That makes it useful now and a handy reference later, like when you want to compare after future work.

How we price flat roof surveys
We confirm the exact price before booking. These are the things that affect it:
- Features like valleys, chimneys, dormers and parapets
- The use of thermal imaging or a drone
- Building height and the viewpoints available
- Commercial roofs and larger buildings
Simple, low roofs take less time to survey than tall or complicated ones, and the package matters as well. We will give you the figure before anything is booked.
Booking your survey
Getting the details right at the start saves time. It is useful to include:
- Whether there’s a loft hatch, a shared roof or tricky access
- Why you want a survey: buying, a leak, a storm or new work
- Your postcode, so we can check access and travel
- The kind of building and roof involved
If you are buying, it is useful to book soon after your offer is accepted, so there is time to use the report before exchange. Otherwise, simply call 07833 053749 or use the contact form whenever suits you.
What happens if roof problems are left?
On a commercial building, a flat roof leak can disrupt tenants, staff and stock. A planned survey lets you budget for work rather than deal with an emergency around the business. Work on a London roof is rarely simple to arrange, with parking, neighbours and access all to think about. Knowing what’s needed early gives you time to plan it calmly.
Flat roof survey starts from £150, including VAT. Basic starts from £150, Standard from £250 and Premium from £400, VAT included, and we can help you choose.

Questions from Dollis Hill
Do you look at commercial flat roofs near Dollis Hill, such as hotels?
Yes, we cover commercial roofs as well as homes. Roof access is agreed with the building manager or owner beforehand.
Will parking be an issue for a roof survey in Dollis Hill?
Sometimes, yes. If Dollis Hill has controlled parking where you are, a visitor permit is the easiest answer, and a driveway is even better.
Does this replace a RICS home survey?
No. It is a specialist roof survey, not a RICS Level 2 or Level 3 building survey. It focuses on the roof and can sit alongside a RICS survey.
Does the report include photographs?
Yes, every report has them. Each finding is shown in a picture where possible, which makes the report easy to follow.
Are you structural engineers?
No. We point out what can be seen, such as sagging or deflection, but we do not carry out calculations or give an engineer’s opinion. Where an engineer is needed, we say so in the report.
Do you climb onto every roof?
Only when it’s safe. Safety comes first, and fragile or steep roofs can’t always be walked on. We use safe viewpoints, the roof space and a drone where it applies, and the report records anything we couldn’t see.
How long is the visit?
It typically takes an hour or two for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. The report follows by email.
Flat roof surveys around Dollis Hill
In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. There are several hotels within about a mile and a half of Dollis Hill. For hotels and other commercial buildings, finding the cause of a flat roof leak quickly keeps rooms in use.
A roof leak in a hotel or guest house around Dollis Hill means lost rooms as well as repairs, so it pays to find faults before guests do. Historic houses such as Heath House, about 2.3 miles east, show how far back building around Dollis Hill goes. On a period home nearby, any flat roof is likely to be a later addition with its own lifespan.

When to book a survey in Dollis Hill
Ponding keeps the covering wet and wears it faster. Blocked outlets, poor falls and a sagging deck are the usual causes. Where trees are close by, leaves and silt can block an outlet within a single autumn.
People normally book a survey when they’ve noticed something like this:
- Splits, cracks and crazing
- Blistering in felt or asphalt
- Damaged trims at the roof edge
- Outlets choked with leaves and silt
Take a building like Our Lady of Grace Catholic Junior School: large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.
Before you book any roof surveyor
- How they’ll see the roof: from the ground, the loft, the roof or by drone
- How soon the report will arrive
- Whether you can ask questions once you have the report
- What’s outside the scope of the survey
How it works
Every roof is different; as a rough guide, the survey takes about one to two hours for a small flat roof at home, and longer for a large commercial one. You’re welcome to ask questions while we’re there. In Dollis Hill, visits are available on weekdays and at weekends. London parking is often by permit or pay-and-display, so it helps to know what’s near you. Upstairs rooms at the back are useful too, as they frequently give the best view of a rear addition.
- We start with the details: the address, the roof’s use and any leaks or stains.
- We view the roof from the ground, from windows and from the roof where it’s safe to do so.
- We check and photograph the covering, the falls, the upstands, the outlets, the trims and any rooflights.
- We check the rooms or spaces under the roof for staining where we can reach them.
- You get a report with photographs and our recommendations.
Getting ready for the survey
- If you are buying, check with the agent that we can get in
- Have any questions written down, so nothing gets missed
- Find any records of previous roof work

Tips that help
A few practical points come up again and again on our surveys. They’re worth knowing whatever the roof:
- Check that new brackets or units haven’t damaged the covering
- Have the roof looked at again after a severe storm
- Never stand on rooflights or fragile sheeting
- Keep records of when the roof was laid and what work has been done
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.
Keep outlets, gutters and hoppers clear, especially after the leaves fall. Water that can drain away does far less harm than water that sits.
Should I look at the roof myself first?
After strong wind, take a look from the pavement or garden: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Leave anything above ground level to a survey.
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it.
