About our roof survey in Harrow on the Hill
A roof survey tells you what condition your roof is in, before small faults become big ones. We look at the coverings, the ridges and hips, the valleys and flashings, the chimneys and the gutters, along with the loft where it is safe to get in. You get a report with photographs and recommendations. Where it’s relevant, the recommendations are prioritised by urgency. We are frequently asked to look into loose ridge or hip tiles and gaps in the roof where coverings have gone, on natural slate, ridges, hips and valleys and clay and concrete tiles.
Many London terraces have a butterfly roof, with two slopes meeting in a central valley gutter that drains to the rear. From the street you see only a parapet wall, so blocked outlets and split linings go unnoticed until water comes through a ceiling. If your home in Harrow on the Hill has one, it needs checking from somewhere that can actually see it.
What you get is a clear record of the roof on the day we saw it. That makes it useful now and a handy reference later, for instance when you want to check whether anything has changed.

How it works
Safety comes first on every visit. Everything that can safely be seen is inspected, and anything we cannot see is noted in the report. Most visits take about 1–2 hours at most homes, rising to roughly 3–4 hours on a commercial building. London terraces rarely offer a view of the whole roof from one spot, so in Harrow on the Hill we work round the house, using the street, the windows, the loft and any safe vantage point behind it. If other people live in the building, let us know who can let us into the shared parts.
- You get in touch with the address and anything you’ve noticed.
- We agree a date, on a weekday, Saturday or Sunday.
- We inspect from ground level, from windows, from the roof space and from the roof where safe.
- We check the coverings, ridges, hips, valleys, flashings, chimneys and gutters, and photograph what we find.
- You receive a written report with photos and recommendations.
Before the survey
- Find any records of previous roof work
- Clear the way to the loft hatch
- Keep pets inside or away from the areas we’re looking at
How to book
If you are buying, it helps to book soon after your offer is accepted, so there’s time to use the report before exchange. Otherwise, simply phone 07833 053749 or use the contact form whenever suits you.
Advice
How we price roof surveys
Prices vary from roof to roof, for these reasons:
- House, block, shop or office
- How complicated the roof is, with its valleys, chimneys and parapets
- How many separate roofs there are, such as extensions, dormers and garages
- The use of thermal imaging or a drone
Simple, low roofs take less time to survey than tall or complicated ones, and the package you pick makes a difference too. We’ll give you the figure before anything is booked.
What we need to know
Some details help us point you to the right survey and price. When you contact us, tell us:
- Anything about access we should know
- Where the property is, with the postcode
- Any marks or damp showing indoors
- The type of building and roof, such as pitched or flat
We confirm the exact price before booking, so you know the cost up front. Roof survey starts from £150, including VAT. For a price for your roof, call 07833 053749 or use the contact form.
When you need someone else
Some things cannot be seen without opening up the roof, so a survey has limits:
- A full building survey of the property
- Whether materials contain asbestos (that needs a specialist asbestos surveyor)
- A promise that the roof will not leak in future
If you’re not sure which survey you need, ring 07833 053749 or send us an email and we will give you a straight answer. What a survey covers and does not.

Roof surveys in Harrow on the Hill: local notes
With Northolt Manor about 2.1 miles south-west, Harrow on the Hill sits in an area with a long building history. If your house is among the older ones, expect a mix of original materials and later repairs on the roof. If the drone is used for your survey, the flight is checked against the Drone Safety Map first.
For landlords with property near Sudbury Hill Harrow station, a roof report between tenancies helps plan work before a small defect becomes a tenant’s leak. Take an older house close to Christ Church: its roof may have old fixings, lead flashings and chimneys that need a closer look.

Useful tips for Harrow on the Hill property owners
Here are a few things we’d tell any owner:
- Watch for slipped slates after bad weather
- Make sure we can open the loft hatch
- Leave roof access to professionals
- Keep the report with your property records
The Premium Survey includes a 12-month follow-up. It shows how the roof has fared over the year, and whether work has done its job.
Keep gutters, valleys and outlets clear of leaves and moss, particularly after autumn. Leave the clearing to a professional. Most overflow damage starts with a blocked gutter.
When to book a survey in Harrow on the Hill
Wherever a roof meets a wall, a chimney or another roof, a flashing keeps water out. Lead can crack, lift or slip with age, and mortar fillets crack. Lead is also a target for theft.
A survey can pick up problems like:
- Water stains on rafters and ceiling joists
- Leaking gutter joints and downpipes
- Cracked mortar along the ridge
- Loose chimney pots
If you live near a park such as Northwick Park, or anywhere with mature trees, autumn leaves can block gutters and valleys, and an overflowing gutter soon means a wet wall.

Questions from Harrow on the Hill
How do I find out if my home in Harrow on the Hill is listed?
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.
Can parking be tricky for a visit in Harrow on the Hill?
It rarely stops a survey, but it’s worth planning. Let us know the parking rules on your street and we will work around them.
How much is a survey?
Prices start from £150, including VAT. Our Basic Survey starts from £150, the Standard Survey from £250 and the Premium Survey from £400, all including VAT.
Can you tell me how long my roof will last?
Not as a figure. The report explains the condition of each part and the signs of wear, with recommendations ranked by urgency.
Is it the same as a RICS Level 2 or Level 3 survey?
No. We check the roof, not the whole building, and it is not a RICS Level 2 or Level 3 survey. Many buyers have both.
How long does the visit take?
The visit usually takes about 1–2 hours for an ordinary house roof, and longer if there are extensions, dormers or several chimneys. We’ll give you an idea of timing as you book.
How quickly will I get the report?
It depends on the package: within 48 hours for Basic, 24 to 48 hours for Standard and the same day for Premium. It is emailed to you.
Why get it checked now?
Planned work is less stressful than an emergency. A survey lets you deal with things in order of urgency, rather than waiting for something to fail. A hidden valley or parapet gutter on a London house can hold water for weeks before anyone notices. By the time a ceiling stains, the timbers underneath may have been wet for a while.
Every price we give includes VAT. Our price is from £150, including VAT. You’ll know the price for the job before you book.
