Roof survey in Harrow: what you get
We inspect everything that’s safely in view: from ground level, from windows, from the roof space and from the roof where conditions allow. The Premium Survey adds thermal imaging and, where it applies, a drone, for roofs that are hard to see well. You do not need to do anything except give us access. Everything we see is photographed for the report. We are often asked to look into worn lead at chimneys and abutments and torn or sagging underlay, on natural slate, lead flashings and flat roofs.
London has a great many flats in converted houses and purpose-built blocks, so roofs are often shared between several households. Whoever looks after the building needs a clear picture of the roof, chimneys and gutters. Leaks from a shared roof rarely affect just one home. A report gives everyone the same picture to plan from, with photos.
We keep jargon out of it: where something needs attention, it says so plainly, and where it can wait, that’s said too.

Why it is worth a survey now in Harrow
Leaving it means relying on what you can see from ground level. You might pay for work that does not fix the real problem, or to a real problem being missed. A survey tells you what actually needs attention. London’s older roofs frequently have bitumen felt underlay or none at all, so once the slates or flashings let water past, little stops it reaching ceilings. Left unchecked, water soaks into timber and plaster and the damage spreads.
Roof survey starts from £150, including VAT. Basic starts from £150, Standard from £250 and Premium from £400, VAT included.

For landlords and managing agents
For a freeholder or residents’ company, a roof report is a sound basis for a maintenance plan, putting the urgent items at the top.
Shared roofs need a little more planning: we need access agreed with the freeholder or managing agent. Mention it when you get in touch and we’ll plan the visit with that in mind.
How the survey works
We don’t take risks to get a closer look. Everything that can safely be seen is inspected, and if part of the roof cannot be seen, the report says so. Most visits take an hour or two for most homes, depending on how many separate roofs there are. In converted houses and mansion blocks, the loft hatch is often on a shared landing. If that applies to your building, it helps to agree access with the neighbours or the managing agent first. Otherwise, the visit in Harrow runs like any other.
- We help you choose a Basic, Standard or Premium Survey.
- We arrive at the agreed time and talk through any concerns.
- We inspect and photograph every part of the roof we can safely see.
- Extra checks are carried out where your package includes them.
- The report is emailed with findings and recommendations.
How to prepare
- Dig out any old roof reports or invoices
- If you’re buying, check with the agent that we can get in
- Make sure we can get to the back of the property

What affects the cost of roof surveys
When we price a survey, we consider:
- The package you choose: Basic, Standard or Premium
- How tall the building is and how easy the roof is to see
- Extra roofs, like extensions, dormers or garages
- Features like valleys, chimneys, dormers and parapets
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how safely it can be seen. Roof survey starts from £150, including VAT.
Booking your survey
Before you get in touch, it’s useful to have:
- When you need the report by
- The property’s address and postcode
- Where any leaks, stains or damp patches show inside
- What made you get in touch
Photos help, if you have them. Take them safely from the ground or a window; never climb up to get a better view. To get started, phone 07833 053749 or send us an email.
Harrow questions
Can a landlord with a rental near Harrow-on-the-Hill station book a roof survey?
Of course. We just need to know who will give access, and the report can go straight to you or your agent.
How do I find out if my home in Harrow is listed?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it is worth checking before planning any.
How experienced are you?
We have been surveying roofs for over 20 years and have carried out more than 5,000 surveys across London and the South East.
How do I arrange a roof survey in Harrow?
Just ring 07833 053749 or use the contact form with the address. We’ll ask a few questions, confirm the price and agree a date.
Is your survey a structural engineer’s report?
No. We report on the roof’s condition, and the Standard and Premium packages include a structural check. It is not a structural engineer’s report and does not include calculations.
I live in a flat. Can you survey the roof?
Yes, once whoever controls the roof agrees access. We check the parts we are given access to, and the report makes that clear.
Does this replace a RICS home survey?
No. Our survey is a roof survey, not a RICS Level 2 or Level 3 survey of the whole building. It focuses on the roof, so it sits alongside a building survey rather than replacing it.

Roof surveys around Harrow
If your survey includes the drone, we check the Drone Safety Map for restrictions before flying. About 1.4 miles north lies Headstone Manor, a reminder of how long the area around Harrow has been built on. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and the council can say whether a home is in a conservation area.
For an older house near a landmark such as Church of St Peter, old fixings, lead flashings and tall chimneys are typical of older roofs. Trees in and around Northwick Park shed leaves that can end up in nearby gutters, and an overflowing gutter soon means a wet wall. If you look after a building such as Whitmore High School, long gutter runs and wide roofs on a building that size are worth checking on a regular cycle.

Roof by roof
Clay plain and peg tiles
Clay tiles are common on older South East homes, and some have Kent peg tiles held by pegs. When pegs or battens rot, tiles slip, leaving gaps along the courses.
Flat roof coverings
Repeated coatings can hide what’s underneath. If the covering would need opening up to know more, we say so.
