Harrow Weald Roof Survey
We take a careful look at the roof at your property in Harrow Weald, with photographs and a written report.
- Cracked mortar along the ridge
- Worn lead at chimneys and abutments
- Leaking gutter joints and downpipes
Leave it or get it looked at?
If you’re planning to sell, a roof survey can help you prepare. You’ll know what a buyer’s survey might pick up. Many older London roofs have only old felt under the slates, or no underlay at all, so a slipped slate can soon mean water inside. Left alone, that means wet timbers and plaster, which is a far bigger job than the roof fault itself.
One thing that affects the price is the package: from £150 for Basic, £250 for Standard and £400 for Premium, including VAT. The roof’s size, height and access matter as well.

Roof surveys for homes and businesses in Harrow Weald
There are three levels of survey: Basic from £150, Standard from £250 and Premium from £400, including VAT. Basic is a visual inspection with photos and written recommendations. Standard and Premium go further, like moisture detection, a structural check, thermal imaging and a drone where it applies. Every package includes a written report. If you’ve noticed debris building up in roof valleys and ponding, splits or blisters on flat roofs, a survey will tell you what’s going on, whatever the roof.
A London butterfly roof slopes down to a central valley gutter that drains to the back of the house. Hidden behind the parapet, that gutter can block or split without anyone seeing it. If your home in Harrow Weald has one, it needs checking from somewhere that can actually see it.
The report records the roof as we found it on the day. It is useful right away, and a good reference for later, for instance when you want to check whether anything has changed.

What a roof survey doesn’t cover
A survey is a careful look at the roof, but it can’t do everything. Its limits include:
- Structural calculations (that is a structural engineer’s job)
- How the roof will behave in every kind of weather
- The condition of the rest of the building (that is a RICS home survey)
If in doubt, phone 07833 053749 or send us an email and we will point you to the right survey. What a survey covers and doesn’t.
What we check
- Ridges, hips and valleys
- The roof space
- Lead flashings
- Flat roofs
- Natural slate
- Clay and concrete tiles
- Chimney stacks

Signs you need a roof survey in Harrow Weald
The coverings are rarely the first thing to fail. ‘Nail fatigue’ is common on slate roofs: the nails rust and the slates slide. On tiled roofs, battens and pegs can rot.
Common reasons to book include:
- Slates or tiles that have slipped or broken
- Loose ridge or hip tiles
- Worn or blocked valleys
- Water stains on rafters and ceiling joists
If you look after a shop, office or commercial unit, for example near St. George's Shopping Centre, a roof report helps plan work around trading rather than after a leak.
What to check before booking
- Will they check the loft as well as the outside?
- Whether you can ask questions once you have the report
- Is VAT included in the price?
- Do they have a CAA Flyer ID and Operator ID for drone work?
Tips from our surveys
Nothing here needs a ladder. Our suggestions:
- Mention any flat roofs as well as the main roof
- Check the roof from ground level after storms
- Don’t climb onto the roof yourself
- Clear the loft hatch area before we arrive
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.
Have the roof surveyed every few years, and after major storms. Regular checks catch problems while they’re small. Compare each report with the last.
Common questions in Harrow Weald
Will parking be an issue for a roof survey in Harrow Weald?
Normally it is manageable with a little notice. Let us know the parking rules on your street and we will work around them.
Is my home in Harrow Weald listed or in a conservation area?
We can’t confirm that for you, but Historic England’s list and your council can. Both listing and conservation areas can limit changes of roofing material.
Do you need to get into the loft?
Where it is relevant to the survey and there is safe access, yes. Please clear anything stored under the hatch, and if the loft cannot be reached safely, the report says so.
How do I book a survey in Harrow Weald?
It’s easiest to call 07833 053749 or send us an email. Let us know the address and a little about the roof. We survey on weekdays and at weekends.
How many surveys have you done?
We have more than 20 years’ experience and have completed over 5,000 surveys.
What does a roof survey include?
Slates or tiles, ridges, hips, valleys, flashings, chimneys and gutters are all checked, along with the loft where it is safe. You get a written report with photographs and recommendations.
Is a roof survey the same as a structural survey?
No. If we see signs that need an engineer, such as serious sagging, we will say so. We don’t provide structural calculations.
How the survey works
Before we start, tell us why you’ve booked: a purchase, a leak, a storm, new work or simply peace of mind. It helps us focus on what matters most to you. Most visits take about one to two hours on an ordinary house, rising to roughly 3–4 hours on a commercial building. In converted houses and mansion blocks, the loft hatch is often on a shared landing. Where that is the case, access needs agreeing with whoever controls that landing. Everything else is planned around the building, not the postcode.
- You get in touch with the address and anything you’ve noticed.
- We agree a date, on a weekday, Saturday or Sunday.
- The roof is inspected from ground level, windows, the loft and the roof itself where it’s safe.
- Slates or tiles, ridges, hips, valleys, flashings, chimneys and gutters are all examined and photographed.
- We email a report with photos and recommendations.
How to prepare
- Clear the way to the loft hatch
- Mention any parking restrictions on your street
- Jot down any questions you want answered

Our price is from £150, including VAT. The exact figure depends on the roof and the package, so ring 07833 053749 or drop us an email with the details.

Roofs, chimneys and gutters in Harrow Weald
About 0.9 miles south-west lies Headstone Manor, a reminder of how long the area around Harrow Weald has been built on. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and the council can say whether a home is in a conservation area. In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. If your home in Harrow Weald is one of them, bay roofs, hips and later dormers each have their own details. Knowing the covering helps explain which parts of a roof are likely to need work first.
Landlords with a home close to Headstone Lane station may find that the gap between tenancies is a good time to have the roof looked at. Take a building like Salvatorian Roman Catholic College: large buildings have long gutter runs and big roofs that need checking like any other.

Can I check my roof myself?
Inside, the loft is a good place to look, with care. Take a torch and only step on boards or joists, and look for staining, damp timber or daylight coming through.
Look up at the roof after a storm, from the ground: 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.
